Description

Technical Field

[0001] This invention relates to the field of engineering survey data processing technology, specifically to an adaptive configuration method for charging pile construction parameters based on multi-source survey data. Background Technology

[0002] Charging pile construction typically includes equipment foundation excavation, cable trench laying, grounding facility installation, and related ancillary works. The configuration of construction parameters needs to comprehensively consider the site's surface elevation, the distribution of underground pipelines or obstacles, the soil bearing capacity, soil resistivity, and site construction boundaries. The above data usually comes from topographic surveys, geophysical exploration, geological surveys, and resistivity tests; different survey data vary in coordinate benchmarks, survey depths, spatial coverage, and data sources.

[0003] Current construction designs typically attach survey results from different sources to the site plan or construction model, and verify the foundation location, cable lines, and grounding facilities based on the survey results. When the foundation location conflicts with underground obstacles, the load-bearing capacity of the area where the foundation is located is insufficient, or the cable lines exceed the construction boundary, adjustments to the foundation location, cable routing, or grounding layout are required.

[0004] However, existing methods typically use survey results as a holistic representation of the construction site, failing to establish a correspondence between the survey data and the actual survey location, depth, and effective coverage boundaries. New foundation excavation areas, trench areas, or grounding areas added after adjustments to construction parameters may exceed the effective coverage of the original survey data. The original survey results are then continued to be used to verify the adjusted construction plan, making it difficult to identify data gaps in the newly added construction areas. Re-surveying the entire construction site would further increase the scope of redundant surveys.

[0005] Furthermore, changes in the foundation location will cause changes in the cable equipment side endpoints and grounding down conductor endpoints, and cable line adjustments may also alter the common trench path or clearance area of ​​grounding facilities. Existing parameter adjustment processes typically handle the foundation, cable lines, and grounding facilities separately, lacking a continuous transmission mechanism between changes in construction area, supplementary survey results, and related construction parameters. Summary of the Invention

[0006] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide an adaptive configuration method for charging pile construction parameters based on multi-source survey data to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an adaptive configuration method for charging pile construction parameters based on multi-source survey data, comprising:

[0008] Obtain the site surface elevation, underground obstacles, stratum bearing capacity, soil resistivity, and site construction boundaries, and form survey attribution units with survey category identifiers according to the survey location, depth, and coverage boundary;

[0009] Based on the initial parameters of the charging pile, construct the foundation construction area, cable line construction area and grounding construction area, and configure category labels according to the survey requirements and overlay them with the same type of belonging unit;

[0010] The obstacle protection zone is formed by the underground obstacle attribution unit and the safety clearance, and the bearing zone is formed by the stratum bearing attribution unit. The construction area of ​​the foundation is compared with the obstacle protection zone and the bearing zone, and the construction area of ​​the cable line and grounding is compared with the obstacle protection zone and the site construction boundary to form a construction conflict record.

[0011] For conflicting objects, candidate adjustment parameters are generated within the range of equipment installation dimensions, standard material specifications, and workable locations. Candidate construction territories are reconstructed, and the areas newly added to the candidate construction territories relative to the current construction territories are taken as incremental territories.

[0012] The incremental territory is overlaid with similar ownership units, the survey gap is supplemented and the survey ownership unit is updated, and the obstacle protection area and bearing area are updated according to the updated survey ownership unit.

[0013] Review the candidate construction areas, retain the candidate adjustment parameters that have not formed construction conflict records, and select the one with the smallest incremental area volume;

[0014] Update the associated parameters according to the connection relationship between the foundation location and the cable equipment side end point, the grounding down conductor end point, and the laying relationship between the cable and the grounding facility. Repeat the overlay verification and territory comparison until there are no survey gaps and no construction conflict records.

[0015] The present invention is further configured such that the acquisition of site surface elevation, underground obstacles, stratum bearing capacity, soil resistivity, and site construction boundaries, and the formation of survey attribution units with survey category identifiers according to survey location, depth, and coverage boundaries, includes:

[0016] According to the survey category, the data of measuring points or lines generated by the survey equipment are associated with the survey location, survey depth, effective detection boundary and source record identifier to generate source survey records;

[0017] Based on the correspondence between the control points of the construction site and the control points of the survey equipment, the plane coordinates and elevation benchmarks of the source survey records are unified to generate spatialized survey records;

[0018] Based on the location of the measuring points or the trajectory of the measuring line, a planar coverage boundary is formed according to the effective detection width of the surveying equipment at the surveying location, and a vertical boundary is defined according to the surveying depth end face, forming a surveying cover associated with the spatialized surveying record;

[0019] The survey cover is overlaid according to the survey category. The survey cover is divided at the intersection of the coverage boundary of adjacent survey cover and the end face of the survey depth. The resulting survey spatial segment is associated with the corresponding spatialized survey record. The survey category identifier is configured according to the spatial boundary and vertical range of the survey spatial segment to generate the survey belonging unit.

[0020] The present invention is further configured such that the construction of the foundation construction area, cable line construction area, and grounding construction area based on the initial parameters of the charging pile includes:

[0021] Based on the installation location and direction of the charging pile, the standard outline of the foundation recorded in the foundation construction drawing is converted to the site coordinate system to form the foundation plane positioning boundary;

[0022] According to the excavation operation clearance specified in the construction specifications, the foundation excavation operation boundary is formed by extending outward along the foundation plane positioning boundary. The vertical range is defined by the site surface and the foundation bottom elevation surface, and the vertical space within the foundation excavation operation boundary is closed to form the foundation construction area.

[0023] Connect the line endpoints and turning control points according to the cable laying sequence to form the line reference path. Continuously unfold the trench cross-section along the line reference path, and connect adjacent trench cross-sections at turning positions and line joint positions to form the cable line construction area.

[0024] The grounding path is formed by connecting the grounding electrode positions and the conductor turning positions according to the grounding connection sequence. The grounding trench section is unfolded along the grounding path, and the grounding electrode burial space and the grounding trench space are connected to form the grounding construction area.

[0025] The present invention is further configured such that configuring category identifiers for construction areas according to survey requirements and overlaying them with similar belonging units includes:

[0026] The survey requirement sections are divided along the surface projection boundary, construction depth boundary, and foundation bottom boundary of the construction area. The surface projection range is taken as the elevation requirement section, the construction depth range as the obstacle requirement section, the space between the foundation bottom and the bottom boundary of the foundation design bearing layer as the bearing requirement section, and the grounding construction area as the resistivity requirement section.

[0027] Each elevation requirement section, obstacle requirement section, bearing capacity requirement section, and resistivity requirement section is assigned a survey category identifier for surface elevation, underground obstacle, stratum bearing capacity, and soil resistivity, and the survey requirement section is associated with its corresponding construction area.

[0028] Spatially overlay the survey requirement sections and survey belonging units with the same survey category identifier, and divide the survey requirement sections at the intersection of the coverage boundary and the survey depth end face to form spatial segments to be corresponded.

[0029] The spatial segments to be corresponded within the coverage boundary and depth range of the survey unit are formed into survey coverage sections. The remaining spatial segments to be corresponded are merged according to spatial continuity to form survey gaps, generating spatial correspondence records between the construction area and the survey unit.

[0030] The present invention is further configured such that the formation of the construction conflict record includes:

[0031] Based on the obstacle space boundary and construction safety clearance corresponding to the obstacle category in the underground obstacle survey unit, an underground obstacle protection area is formed by extending outward along the obstacle space boundary, and the outer edge of the underground obstacle protection area is taken as the underground obstacle protection boundary.

[0032] According to the spatial boundaries and bearing levels of the stratigraphic bearing units, spatially continuous stratigraphic bearing units with the same bearing level are merged to form bearing zones;

[0033] The basic construction area is superimposed with the underground obstacle protection area and the load-bearing zone. The cable line construction area and the grounding construction area are superimposed with the underground obstacle protection area and the site construction boundary. The corresponding construction area is divided along the underground obstacle protection boundary, the load-bearing zone boundary and the site construction boundary to form a construction space segment associated with the construction object.

[0034] Construction space sections that enter the underground obstacle protection area, are located outside the site construction boundary, or have a corresponding bearing capacity lower than the foundation design bearing capacity are designated as conflict space sections. These conflict space sections are then associated with the construction object, conflict category, and source of constraint boundary to generate construction conflict records.

[0035] The present invention is further configured such that, for the conflicting object, generating candidate adjustment parameters within the range of equipment installation dimensions, standard material specifications, and workable locations includes:

[0036] The conflict space section, the source of the constraint boundary and the construction object are associated. The parameter adjustment direction is formed according to the direction of moving away from the obstacle protection area, entering the inside of the site construction boundary or entering the load-bearing zone with a load-bearing level not lower than the foundation design load-bearing level. The range of the site that can be constructed is deducted from the obstacle protection area to form the candidate construction area.

[0037] The area located in the qualified bearing zone of the candidate construction area is taken as the candidate layout area of ​​the foundation. The candidate layout area of ​​the foundation is shrunk inward according to the equipment installation size and the foundation excavation operation boundary to form the layout area of ​​the foundation center. The intersection of the foundation adjustment line formed by the original foundation center along the parameter adjustment direction and the layout area of ​​the foundation center is taken as the candidate foundation position.

[0038] The spatially continuous area in the candidate construction area is used as the candidate channel for the line and grounding. The endpoints of the cable line and the connection endpoints of the grounding electrode remain unchanged. The boundary turning positions of the candidate channels are connected in a spatially continuous order to form the candidate laying path. Candidate laying paths that do not meet the laying conditions are excluded based on the minimum bending radius and laying cross-section corresponding to the standard material specifications.

[0039] The candidate foundation location or candidate laying path is associated with the positioning location, line control point, laying path and material specifications of the construction object to generate candidate adjustment parameters.

[0040] The present invention is further configured such that, in the reconstructing of the candidate construction area, the area newly added to the candidate construction area relative to the current construction area is taken as the incremental area, includes:

[0041] Replace the current construction parameters of the corresponding construction object with the candidate foundation location or candidate laying path in the candidate adjustment parameters, and reconstruct the geometric boundary of the corresponding construction object according to the replaced foundation plane positioning boundary, line control point or laying path to generate candidate construction territory.

[0042] The candidate construction area is spatially overlaid with the current construction area, and the candidate construction area and the current construction area are divided at the intersection of their boundaries to form a spatial segment of the construction area.

[0043] The spatial segments located inside the candidate construction area and outside the current construction area are taken as new spatial segments. The new spatial segments that belong to the same construction object and are spatially continuous are merged to form an incremental area.

[0044] The incremental domain is associated with the candidate adjustment parameters, construction objects, candidate construction domains, and the current construction domain to generate an incremental domain record.

[0045] The present invention is further configured such that supplementing the survey gap and updating the survey attribution unit includes:

[0046] Associate the incremental territory with the construction object to which it belongs, configure category identifiers for the incremental territory according to the survey requirements of the construction object, and spatially overlay the incremental territory with the same type of survey unit.

[0047] The incremental territory is divided along the coverage boundary and depth face of the survey unit. Spatial segments within the coverage area of ​​the same type of survey unit are taken as incremental coverage segments, and the remaining spatial segments are merged according to spatial continuity to form survey gaps.

[0048] Using one side boundary of the survey gap as the starting point, survey points or survey lines are laid out sequentially according to the single effective detection range of the survey equipment, so that the effective detection boundaries of adjacent survey points or survey lines are connected to each other, and the supplementary survey depth is not less than the construction depth of the incremental area.

[0049] The supplementary survey points or survey lines are associated with the actual survey range to form a supplementary survey cover. When the supplementary survey cover is spatially continuous with the same type of survey unit, it is merged and the coverage boundary, survey depth and source record association are updated. When the space is not continuous, a new survey unit is generated based on the supplementary survey cover.

[0050] The present invention is further configured such that updating the obstacle protection area and bearing capacity zone according to the updated survey attribution unit and verifying the candidate construction area includes:

[0051] The obstacle space boundary is re-formed based on the updated underground obstacle attribution unit, and the obstacle space boundary is expanded according to the construction safety clearance to form an updated obstacle protection area. The bearing zone is re-divided based on the updated stratum bearing attribution unit.

[0052] The candidate foundation construction area is spatially superimposed with the updated obstacle protection area and load-bearing zone. The candidate foundation construction area is divided along the obstacle protection boundary and the load-bearing zone boundary to form the foundation verification section.

[0053] The candidate cable line construction area and the candidate grounding construction area are spatially superimposed with the updated obstacle protection area and site construction boundary, respectively. The corresponding candidate construction area is divided along the obstacle protection boundary and site construction boundary to form the line verification section and the grounding verification section.

[0054] According to the candidate adjustment parameters, the candidate adjustment parameters of the foundation that have not entered the obstacle protection area and whose bearing capacity is not lower than the foundation design bearing capacity, as well as the candidate adjustment parameters of the line or grounding that have not entered the obstacle protection area and are located inside the site construction boundary, are selected as the candidate adjustment parameters that pass the review. The candidate adjustment parameter with the smallest corresponding incremental area is selected as the candidate adjustment parameter that passes the review.

[0055] The present invention is further configured such that updating the associated parameters according to the connection relationship between the foundation location and the cable equipment side endpoint and the grounding down conductor endpoint, and the laying relationship between the cable and the grounding facility includes:

[0056] When the selected candidate adjustment parameters include the base position, the updated base position is associated with the charging pile wiring position and the grounding down conductor connection position respectively. The charging pile wiring position is taken as the cable equipment side end point, and the grounding down conductor connection position is taken as the grounding down conductor equipment side end point.

[0057] Keeping the cable power supply end point unchanged, connect the cable equipment end point, the candidate line control point and the cable power supply end point to form updated cable line parameters, and unfold the trench cross section along the updated line reference path to form an updated cable line construction area.

[0058] According to the cable and grounding facility laying relationship defined in the construction design, when laying in a common trench, the laying path of the grounding connection conductor is adjusted along the updated line reference path. When laying separately, the construction area of ​​the updated cable line is expanded according to the design clearance. The area enclosed by the site construction boundary is deducted from the expanded area to form a grounding candidate laying area. The grounding down conductor equipment side end point and the grounding electrode connection end point are connected in the grounding candidate laying area to form updated grounding construction parameters.

[0059] Based on the updated basic construction parameters, cable line parameters, and grounding construction parameters, the construction domain is reconstructed and an incremental domain is formed. Supplementary surveys are conducted for survey gaps. When construction conflict records are generated, candidate adjustment parameters are regenerated for the conflict objects. The process of updating associated parameters, verifying coverage, and comparing domains is repeated until there are no survey gaps and no construction conflict records.

[0060] This invention provides an adaptive configuration method for charging pile construction parameters based on multi-source survey data. The method acquires site surface elevation, underground obstacles, stratum bearing capacity, soil resistivity, and site construction boundaries, forming survey attribution units with survey category identifiers according to survey location, depth, and coverage boundaries. Based on the initial parameters of the charging pile, it constructs foundation construction areas, cable line construction areas, and grounding construction areas, configuring category identifiers according to survey requirements and overlaying them with similar attribution units. An obstacle protection zone is formed by the underground obstacle attribution unit and safety clearance, and a bearing capacity zone is formed by the stratum bearing capacity attribution unit. The foundation construction area is compared with the obstacle protection area and bearing capacity zone, and the cable line and grounding construction areas are compared with the obstacle protection area and site construction boundaries to form a construction conflict record. For conflict targets, candidate adjustment parameters are generated within the range of equipment installation dimensions, standard material specifications, and feasible construction locations. Candidate construction territories are reconstructed, and the newly added areas relative to the current construction territories are taken as incremental territories. These incremental territories are overlaid with similar attribution units. Survey gaps are supplemented with additional surveys, and the survey attribution units are updated. The obstacle protection area and load-bearing zone are updated based on the updated survey attribution units. Candidate construction territories are reviewed, retaining candidate adjustment parameters without construction conflict records and selecting the smallest incremental territories. Related parameters are updated according to the connection relationship between the foundation location and the cable equipment side endpoints, grounding down conductor endpoints, and the laying relationship between the cable and grounding facilities. This process of overlay verification and territories comparison is repeated until there are no survey gaps and no construction conflict records. The beneficial effects include:

[0061] 1. Clear spatial attribution of survey data: Survey data is classified into categories based on the survey location, depth, and coverage boundaries, so that the construction area corresponds to the survey data with actual spatial coverage, reducing the use of survey results beyond the effective survey range;

[0062] 2. Incremental area occupancy triggers targeted supplementary survey: Incremental areas are formed by the spatial difference between candidate construction areas and current construction areas. Supplementary surveys are only carried out on survey gaps that are not covered by the same type of survey unit, reducing the scope of repeated surveys after the adjustment of construction parameters.

[0063] 3. Collaborative update of associated construction parameters: Based on the supplementary survey results, the candidate construction area is reviewed, and the associated parameters are updated according to the foundation location, cable endpoints, and grounding laying relationship, so that the adjustment process of foundation, cable line and grounding facilities maintains spatial and construction relationship consistency.

[0070] Example 1:

[0071] An adaptive configuration method for charging pile construction parameters based on multi-source survey data, such as Figure 1 As shown, it includes:

[0072] Obtain the site surface elevation, underground obstacles, stratum bearing capacity, soil resistivity, and site construction boundaries, and form survey attribution units with survey category identifiers according to the survey location, depth, and coverage boundary;

[0073] Based on the initial parameters of the charging pile, construct the foundation construction area, cable line construction area and grounding construction area, and configure category labels according to the survey requirements and overlay them with the same type of belonging unit;

[0074] The obstacle protection zone is formed by the underground obstacle attribution unit and the safety clearance, and the bearing zone is formed by the stratum bearing attribution unit. The construction area of ​​the foundation is compared with the obstacle protection zone and the bearing zone, and the construction area of ​​the cable line and grounding is compared with the obstacle protection zone and the site construction boundary to form a construction conflict record.

[0075] For conflicting objects, candidate adjustment parameters are generated within the range of equipment installation dimensions, standard material specifications, and workable locations. Candidate construction territories are reconstructed, and the areas newly added to the candidate construction territories relative to the current construction territories are taken as incremental territories.

[0076] The incremental territory is overlaid with similar ownership units, the survey gap is supplemented and the survey ownership unit is updated, and the obstacle protection area and bearing area are updated according to the updated survey ownership unit.

[0077] Review the candidate construction areas, retain the candidate adjustment parameters that have not formed construction conflict records, and select the one with the smallest incremental area volume;

[0078] Update the associated parameters according to the connection relationship between the foundation location and the cable equipment side end point, the grounding down conductor end point, and the laying relationship between the cable and the grounding facility. Repeat the overlay verification and territory comparison until there are no survey gaps and no construction conflict records.

[0079] The present invention is further configured such that the acquisition of site surface elevation, underground obstacles, stratum bearing capacity, soil resistivity, and site construction boundaries, and the formation of survey attribution units with survey category identifiers according to survey location, depth, and coverage boundaries, includes:

[0080] According to the survey category, the data of measuring points or lines generated by the surveying equipment are associated with the survey location, survey depth, effective detection boundary, and source record identifier to generate a source survey record. Specifically, four coordinate control points are set up at a construction site that is 30 meters long and 20 meters wide and planned to have 6 DC charging piles. The southwest control point is used as the origin of the site coordinates. RTK surveying equipment is used to collect the ground elevation. The equipment output frequency is selected as 2 Hz within the range of 1 Hz to 5 Hz. The surveying line is moved along a 1-meter interval and measuring points are added at slope inflection points, road edges, and drainage edges. The data is generated through the NMEA interface, including point numbers, Elevation data, including plane coordinates, elevation, positioning status, and acquisition time, was collected using a ground-penetrating radar with a center frequency of 400 MHz. The radar center frequency could be selected within the range of 200 MHz to 600 MHz. The survey line spacing was 80 cm, the track spacing was 5 cm, and the effective detection depth was 3 meters. Survey line data, including survey line number, track number, acquisition location, two-way propagation time, and reflection amplitude, was generated through the radar data interface. Stratigraphic bearing capacity data was collected using drilling and in-situ testing equipment. The exploration point spacing was 5 to 10 meters, the exploration depth was 5 meters, and the data was collected every 20 cm along the depth. A stratigraphic record was created, and the stratigraphic interface depth and foundation bearing capacity were converted into structured data through the survey report interface. Soil resistivity data were collected using the Wenner four-electrode method, with four electrodes arranged at equal intervals. The electrode spacing 'a' was successively set to 1 meter, 2 meters, and 4 meters, and the electrode penetration depth 'h' was no greater than 'a' divided by 20. Each spacing was measured three times along two mutually perpendicular directions. A current 'I' was injected into the outer electrode, and a voltage 'U' was measured at the inner electrode. The soil resistivity 'ρ' was calculated using the formula 'ρ = 2πaU / I'. The median of the three measurements was used as the measured value for the corresponding electrode spacing. The site construction boundary was defined using... The closed boundaries in the overall construction plan are imported through the DXF interface. Then, each measurement point or line data is associated with the survey category, survey location, survey depth, effective detection boundary, and source record identifier. The effective detection boundary is the maximum spatial boundary that the survey equipment can maintain the specified detection resolution after on-site calibration. The source record identifier consists of the survey category code, equipment number, acquisition date, and record sequence number, which is used to maintain the correspondence between the survey results and the original equipment records. The source survey record is generated from the above fields, thereby completing the source constraints and initial spatial range limitation of different survey data.

[0081] Based on the correspondence between control points at the construction site and control points for the deployment of survey equipment, the plane coordinates and elevation datum of the source survey records are unified to generate spatialized survey records. Specifically, the source survey records undergo quality screening, noise processing, and spatial datum unification processing in sequence. Only measurement points with fixed RTK solution states and plane accuracy no greater than 3 cm and vertical accuracy no greater than 5 cm are retained in the surface elevation records. Ground penetrating radar records are first zero-time calibrated according to the starting position of the direct air wave, then baseline drift is eliminated using the median of a single channel, and the background response is formed using the median of the sampling positions at the same time for 20 adjacent channels. The background response is subtracted from the original reflection amplitude to preserve... For reflection zones with a signal-to-noise ratio of not less than 6 dB and consecutive reflections in adjacent radar channels, if the difference between the maximum and minimum values ​​of three soil resistivity measurements at the same electrode spacing exceeds 10% of the median, a new measurement is performed. Records lacking exploration point coordinates, stratigraphic interface depths, or bearing capacity in the stratigraphic bearing record are not included in subsequent spatial processing. A correspondence between survey coordinates and site coordinates is established using four site control points. The six transformation coefficients in x = a1E + a2N + a3 and y = b1E + b2N + b3 are solved using three non-collinear control points, where E and N are survey plane coordinates, and x and y are site plane coordinates. a3, b1, b2, and b3 are affine transformation coefficients for converting survey plane coordinates to site plane coordinates; a1 and a2 are transformation coefficients for survey coordinates E and N to the site x-coordinate; a3 is the translation coefficient in the site x-coordinate direction; b1 and b2 are transformation coefficients for survey coordinates E and N to the site y-coordinate; b3 is the translation coefficient in the site y-coordinate direction. The fourth control point is used to calculate the planar distance error between the transformed position and the measured position of the control point. When the planar distance error exceeds the RTK planar accuracy limit of 3 cm, the control point correspondence and coefficients are recalculated. The elevation is calculated using z = H - H0, where H is the source survey record height. In the process, H0 is the elevation of the origin of the site coordinate system. The obstacle depth of the ground-penetrating radar is converted according to d = vt / 2, where t is the two-way propagation time of the reflected signal, and the propagation speed v is calculated through a known burial depth calibration body. In the example, the burial depth of the calibration pipeline is 80 cm and the two-way propagation time is 16 nanoseconds, resulting in v = 10 cm per nanosecond. When the two-way propagation time of the obstacle reflection is 24 nanoseconds, the converted obstacle depth is 120 cm. Finally, the converted planar position, surface elevation, upper depth boundary, lower depth boundary, survey category, effective detection boundary, and source record identifier are associated to form a spatialized survey record, so that the subsequent coverage boundary calculation adopts a unified coordinate and a unified depth benchmark.

[0082] Based on the location of the measuring points or the trajectory of the measuring lines, a planar coverage boundary is formed according to the effective detection width of the surveying equipment at the survey location, and a vertical boundary is defined according to the end face of the survey depth, forming a survey coverage body associated with the spatialized survey record. Specifically, planar coverage boundaries and vertical boundaries are constructed according to the geometric type of the spatialized survey record. For point-type survey records, a circular planar coverage boundary is formed with the measuring point as the center and according to the effective control radius r obtained from the field calibration. For line-type survey records, a strip-shaped planar coverage boundary is formed by extending half of the effective detection width w to both sides of the measuring line trajectory as the center. For area-type survey records, the closed outer edge of the actual equipment deployment area is used as the planar coverage boundary. The vertical boundary of the surface elevation record is the allowable elevation interval formed by 5 cm above and below the measured surface elevation. The vertical boundary of the underground obstacle record is the boundary from the ground surface to the end face of the radar's effective detection depth. For the stratum bearing capacity record, adjacent exploration points are first connected, and a vertical dividing line is drawn at the midpoint of the connecting line. The space enclosed by the dividing line and located within the site construction boundary is the planar control area of ​​the exploration point. When any point in the control area reaches the corresponding When the distance between exploration points exceeds the upper limit of the designed spacing of 10 meters, the excess portion is retained as uncovered space. The vertical boundary for the record is the upper and lower boundaries of the corresponding stratigraphic interface. The soil resistivity record uses the range between the outermost electrodes of the quadrupole layout line as the vertical boundary, extends to both sides of the layout line with the electrode spacing 'a' to form the lateral boundary, and uses the space from the ground surface to depth 'a' as the vertical range. The planar cover boundary and the vertical boundary are closed to form the survey cover. In the example, the radar survey line length of number GPR001 is 10 meters. The effective detection width is 60 cm, the effective detection depth is 2 m, the horizontal coordinate of the center of the survey line is 5 m, the horizontal coordinate range of the formed survey cover is 470 cm to 530 cm, the longitudinal length is 10 m, the vertical depth is 0 m to 2 m, and the volume of the cover is 12 cubic meters, which is 60 cm multiplied by 10 m and then multiplied by 2 m. The above cover only corresponds to the spatial range that GPR001 can actually support for underground obstacle judgment, thereby converting the equipment detection capability, actual deployment location and survey depth into a physical boundary that can be spatially superimposed.

[0083] Overlay survey covers according to survey categories. Divide the survey covers at the intersection of the cover boundaries of adjacent survey covers and at the survey depth facets. Associate the resulting survey spatial segments with the corresponding spatialized survey records. Configure survey category identifiers based on the spatial boundaries and vertical extent of the survey spatial segments to generate survey attribution units. Specifically, process survey covers separately according to survey categories. First, project all planar cover boundaries corresponding to the same survey category onto the site plane. Insert dividing nodes at the boundary intersections and connect adjacent nodes to form closed planar segments. Then, arrange the upper and lower depth faces of the corresponding survey covers in elevation order, using every two adjacent depth faces for division. Closed planar segments form three-dimensional survey spatial segments. Each survey spatial segment is verified item by item to ensure it is completely within the survey cover. Source record identifiers that completely cover the survey spatial segment are grouped into source association items. Adjacent survey spatial segments with the same survey category, the same source association items, and sharing a complete boundary surface are merged. The outer boundary of the merged spatial segment is used as the cover boundary, and the range between the highest and lowest faces is used as the survey depth. After configuring corresponding survey category identifiers, survey attribution units are generated. A survey attribution unit represents the smallest continuous space where the survey category, effective coverage space, and source record association remain unchanged. Spatial segmentation uses... The boundary tolerance ε is taken as the maximum planar distance error obtained from the control point verification in step two, and is not greater than 3 cm. Boundary fragments with a width not greater than ε are merged into adjacent spatial segments with the same source correlation. Spatial segments that cannot be completely covered by any similar survey cover and have a width greater than ε form survey gaps and trigger supplementary survey tasks containing gap boundaries, survey categories, and required depths. In the example, the horizontal coordinate range of the GPR001 cover is 470 cm to 530 cm, and the parallel survey line covered by the GPR002 cover is 550 cm to 610 cm. Both survey lines are 10 meters long and have a detection depth of 2 meters. The total volume of the two survey covers is 24 cubic meters. Using two survey lines to enclose the boundary will mark the 28 cubic meter space between 470 cm and 610 cm as covered. This step creates a survey gap between 530 cm and 550 cm, with a width of 20 cm, a length of 10 m, a depth of 2 m, and a volume of 4 cubic meters. Then, a supplementary survey line numbered GPR003 is added at the horizontal coordinate of 540 cm to form a supplementary survey cover with a width of 60 cm. After re-executing source record association, spatial segmentation, and attribution unit generation, the 4 cubic meter survey gap is covered by the supplementary survey cover, and the survey gap record is removed. This completes the closed-loop verification of survey data acquisition, spatialization processing, cover construction, gap-triggered supplementary survey, and attribution unit update.

[0084] The present invention is further configured such that the construction of the foundation construction area, cable line construction area, and grounding construction area based on the initial parameters of the charging pile includes:

[0085] Based on the installation location and direction of the charging piles, the standard outline of the foundation recorded in the charging pile foundation construction drawings is converted to the site coordinate system to form the foundation plane positioning boundary. Specifically, a DC charging station construction site with a length of 30m and a width of 20m is selected, with a single charging pile with a rated power of 240kW as the construction object. The charging pile foundation construction drawings, equipment installation drawings, and site general plan are imported in one go through the DXF interface according to the approved version. A rectangular foundation standard outline with a length of 1.6m and a width of 0.9m is obtained from the foundation construction drawings. The foundation standard outline is based on the center of the foundation as the local origin, and the longitudinal and transverse directions of the equipment are used as coordinates. The foundation's outer edge line extends along the boundary direction; drawing dimensions are converted from millimeters to meters, duplicate outlines are deleted, and the foundation's outer edge line is connected according to the line segment endpoints. Endpoint verification is performed on outlines where the distance between the first and last endpoints is greater than 0.02m, with 0.02m taken from the allowable deviation for plane layout specified in the construction survey plan; RTK equipment is used to continuously collect installation position data for 5 seconds at a frequency of 2Hz, retaining only fixed solution records. The last fixed solution record where continuous coordinate changes are no greater than 0.02m is taken as the foundation's center position, yielding a foundation center x-coordinate of 12m and y-coordinate of 8m; the same method is used to obtain... The control point on the front of the equipment has an abscissa of 13m and an ordinate of 8.5m. Dividing the abscissa difference and ordinate difference between the control point and the foundation center by the distance between the two points yields two longitudinal directional components. These longitudinal components are then interchanged, and the sign of one component is changed to obtain the abscissa component perpendicular to the longitudinal direction of the equipment. For each vertex of the foundation's standard contour, its local longitudinal coordinate is multiplied by the longitudinal directional component, and its local abscissa is multiplied by the abscissa component. These results are then added to the coordinates of the foundation center, yielding abscissa and ordinate of 12.514m and 8.5m respectively. Four site vertices with dimensions of 0.760m, 12.917m and 7.955m, 11.486m and 7.240m, and 11.083m and 8.045m are identified. These four site vertices are connected and closed according to the vertex order in the foundation standard outline to form the foundation plane positioning boundary. The distance between adjacent vertices is compared item by item with the dimensions indicated on the foundation construction drawings. If the difference is no greater than 0.02m, the foundation plane positioning boundary is retained; if the difference exceeds 0.02m, the drawing units, installation position, and direction control points are rechecked to maintain the correspondence between foundation dimensions, installation position, installation direction, and drawing version.

[0086] According to the excavation operation clearance specified in the construction specifications, the foundation excavation operation boundary is formed by extending outward from the foundation plane positioning boundary. The vertical range is defined by the site surface and the foundation bottom elevation, and the vertical space within the foundation excavation operation boundary is closed to form the foundation construction area. Specifically, a 0.4m excavation operation clearance is obtained from the approved construction organization design. This clearance represents the space reserved between the outer edge of the foundation entity and the outer edge of the excavation pit for formwork installation, personnel operation, and backfilling and compaction. The allowable range in the construction organization design is 0.3m to 0.8m. Half the foundation length, i.e., 0.8m... Adding m to the clear distance for excavation operations yields a longitudinal half-width of 1.2m for the foundation excavation area. Adding half the foundation width, 0.45m, to the clear distance for excavation operations yields a transverse half-width of 0.85m for the foundation excavation area. Extending outwards by 0.4m along both the longitudinal and transverse sides of the foundation's horizontal positioning boundary, and then extending and intersecting at the intersection of adjacent extended boundaries, a foundation excavation operation boundary is formed, measuring 2.4m in length and 1.7m in width. Using a total station, the elevation of the four corner points of the foundation excavation operation boundary is re-measured; the elevation difference between the measured points is no greater than 0.0m as specified in the construction surveying plan. When the elevation difference exceeds 0.02m, the foundation excavation operation boundary is divided into triangular sections, and the corresponding ground surface is formed by three measured elevation points in each triangular section. The foundation bottom depth relative to the ground surface is obtained from the foundation construction drawings at 1.2m. The foundation excavation operation boundary is used as the horizontal boundary, the ground surface as the upper boundary, and the foundation bottom elevation as the lower boundary. Connecting the horizontal and vertical boundaries forms a closed space. In this embodiment, the elevation difference of the four corner points does not exceed 0.02m, and the foundation excavation plane... The volume is 4.08m² by multiplying 2.4m and 1.7m. The volume of the foundation construction area is 4.896m³ by multiplying 4.08m² and 1.2m. The surface projection of the foundation construction area is overlaid with the site construction boundary. The bottom elevation of the foundation construction area is compared with the elevation on the foundation construction map. If the surface projection is inside the site construction boundary and the bottom elevation difference is not greater than 0.02m, the foundation construction area is retained. Otherwise, the foundation location or elevation benchmark is returned for verification. This unifies the foundation entity, the pit operation space, and the actual construction depth into a spatially continuous construction range.

[0087] The cable laying sequence is followed by connecting the line endpoints and turning control points to form a baseline path. Trench sections are continuously laid along this baseline path, and adjacent trench sections are connected at turning points and line joint locations to form the cable laying construction area. Specifically, the cable power supply side endpoints, turning control points, line joint locations, and charging pile equipment side endpoints are obtained from the approved electrical construction drawings via a DXF interface. Drawing data is re-imported when the approved version changes. Here, line endpoints indicate the locations where the cable connects to the power supply equipment or charging pile terminals, and turning control points indicate the locations where the cable laying direction changes. The line joint location indicates the intermediate connection position of the cable as specified in the construction drawing; the imported points are converted to the site coordinate system used in step 1, and duplicate control points with a coordinate spacing of no more than 0.02m are merged. The remaining points are arranged according to the laying sequence number marked on the construction drawing; in this embodiment, the power supply side endpoints with horizontal and vertical coordinates of 2m and 4m, the first turning control point of 6m and 4m, the second turning control point of 6m and 7m, and the equipment side endpoints of 11m and 7m are obtained in sequence and connected to form the line reference path. The lengths of the three line sections are 4m, 3m, and 5m, respectively, with a total length of 12m; from the cable trench construction The detailed drawings show a trench width of 0.6m and a trench depth of 0.8m. A rectangular trench section, 0.6m wide and 0.8m deep, is continuously translated along each line segment to form three segmented trench spaces. At two turning control points, turning connection areas with sides of 0.6m are formed centered on the control points. These turning connection areas are merged with adjacent segmented trench spaces, with overlapping areas retained only once. When line joints exist, joint spaces are formed according to the length, width, and burial depth recorded in the joint well construction drawings, and these joint spaces are connected to the trench spaces on both sides. This embodiment does not have intermediate joints. The baseline path has no self-intersections or overlapping sections. The planar area occupied by the cable line is 7.2m² by multiplying the 0.6m trench width by the 12m path length. The construction volume of the cable line is 5.76m³ by multiplying the 7.2m² by the 0.8m trench depth. Horizontal and vertical sections are taken at two turning control points. The construction area of ​​the cable line is retained when the sections are continuous, with a width of not less than 0.6m and a depth of not less than 0.8m. If there is a break or the section size is insufficient, the corresponding turning position is reconnected, so that the straight trench, turning trench and joint construction space form a continuous area.

[0088] The grounding path is formed by connecting the grounding electrode positions and the turning positions of the connecting conductors according to the grounding connection sequence. The grounding trench cross-section is then developed along the grounding path, connecting the grounding electrode burial space with the grounding trench space to form the grounding construction area. Specifically, the grounding down conductor endpoints, grounding electrode positions, connecting conductor turning positions, and grounding trench cross-sections are obtained from the approved grounding construction drawings via a DXF interface. The grounding electrode length and burial hole diameter are obtained from the material specifications. The grounding down conductor endpoints indicate the position where the charging pile grounding down conductor enters the underground grounding facility; the grounding electrode position indicates the center position of the vertical grounding electrode; the connecting conductor turning position indicates the position where the underground grounding conductor changes its laying direction; and the grounding electrode burial space indicates the installation area. The vertical construction space occupied by the installation of grounding electrodes and the formation of the surrounding filling layer is determined. The grounding points are uniformly converted to the site coordinate system and arranged according to the connection sequence indicated on the construction drawings. In this embodiment, the grounding down conductor endpoints with horizontal and vertical coordinates of 12m and 8.8m, the first grounding electrode positions of 12m and 11m, and the second grounding electrode positions of 16m and 11m are obtained sequentially. After connection, a grounding layout path with a total length of 6.2m is formed. The trench width of 0.5m and the trench depth of 0.8m are obtained from the grounding construction details. The corresponding rectangular cross-section is continuously translated along the grounding layout path, forming a turning connection area with a side length of 0.5m at the first grounding electrode position. After merging the overlapping spaces, a grounding trench space is formed, the volume of which is 0.5m wide. Multiplying the 0.8m trench depth and 6.2m path length sequentially yields 2.48m³; using a 2.5m long vertical grounding electrode, and following the construction process specification of a 0.15m burial hole diameter, a cylindrical burial space with a radius of 0.075m and extending 2.5m downwards from the bottom of the trench is formed, centered on the grounding electrode location. The volume of each burial space is approximately 0.0442m³, calculated by multiplying the square of the burial hole radius, pi, and burial depth sequentially, totaling approximately 0.0884m³ for both spaces; connecting the upper ends of the two grounding electrode burial spaces to the bottom of the grounding trench, the grounding trench space and the grounding electrode burial space are merged, forming a grounding construction area of ​​approximately 2.568m³; below the ground surface 0. A horizontal cross-section is taken at 5m to verify the continuity of the grounding trench. A horizontal cross-section is taken at 2m below the ground surface to verify the existence of two grounding electrode sections with a diameter of 0.15m. Then, the excavation dimensions, trench width, construction depth, and grounding electrode burial depth are obtained from the reverse vectors of the foundation construction area, cable line construction area, and grounding construction area. The reverse vector values ​​are compared with the corresponding construction drawing data item by item. When the boundary coordinate difference is not greater than 0.02m and there is no spatial break at the connection position, the construction area construction is completed. If the deviation exceeds the allowable deviation or there is a break, the corresponding foundation boundary, line control point, or grounding point is returned to reprocess. This forms a closed-loop process of construction drawing data acquisition, coordinate unification, area construction, dimension verification, and abnormal repair.

[0089] The present invention is further configured such that configuring category identifiers for construction areas according to survey requirements and overlaying them with similar affiliation units includes:

[0090] The survey requirements are divided into sections along the surface projection boundary, construction depth boundary, and foundation bottom boundary of the construction area. The surface projection range is designated as the elevation requirement section, the construction depth range as the obstacle requirement section, the space between the foundation bottom and the bottom boundary of the foundation design bearing layer as the load-bearing requirement section, and the grounding construction area as the resistivity requirement section. Specifically, the aforementioned 30m long and 20m wide DC charging station construction site is selected, and the already constructed foundation construction area, cable line construction area, and grounding construction area are taken as the processing objects. Among them, the foundation construction area has a planar dimension of 2.4m × 1.7m and a construction depth of 1m. The trench width for cable line construction is 0.6m and the construction depth is 0.8m. The grounding construction area includes a grounding trench 0.5m wide and 0.8m deep, as well as a 2.5m long grounding electrode burial space extending from the bottom of the trench. The planar boundary of the construction area is obtained through the DXF interface, the vertical boundary and construction object identification are obtained through the IFC interface, and the top and bottom boundaries of the foundation design bearing layer are obtained through the survey report data interface. Static drawing data is re-imported when the approved version changes. The site elevation data uses the measurement results collected at a frequency of 2Hz and filtered by a fixed solution. The data from different interfaces are used to determine the boundaries of the construction area. The unit of length is standardized to meters, and the elevation is uniformly converted to the site elevation datum. Isolated edges with lengths less than the accuracy of the construction drawings and not connected to the construction object are deleted. Adjacent edges with a connection point spacing of no more than 0.02 meters are formed to create closed surface projection boundaries, construction depth boundaries, and foundation bottom boundaries. The projections of the foundation construction area, cable line construction area, and grounding construction area onto the site surface are respectively designated as elevation requirement sections. Elevation requirement sections represent the planar range within which surface elevation data is needed to control the excavation starting face and trench elevation. The space from the site surface to the bottom of each construction area is designated as the obstacle requirement area. The obstacle requirement section represents the 3D construction space that needs to be covered by underground obstacle survey data. In this embodiment, the geological survey report records the range of 1.4m to 2.3m below the foundation bottom surface as the bearing stratum that meets the design bearing requirements. The foundation design document takes 1.0m below the foundation bottom surface as the bottom boundary of the bearing stratum check. Therefore, the bearing requirement section is formed by extending 1.0m downward along the planar boundary of the foundation entity bottom surface. The grounding trench space and the grounding electrode burial space are combined to form the resistivity requirement section, so that the soil resistivity data requirement range covers both the horizontal grounding conductor and the vertical grounding electrode, completing the geometric division of the four types of survey requirement sections.

[0091] Each elevation requirement section, obstacle requirement section, bearing capacity requirement section, and resistivity requirement section is assigned a survey category identifier for surface elevation, underground obstacle, stratum bearing capacity, and soil resistivity. The survey requirement sections are then associated with their respective construction territories. Specifically, the four survey category codes for surface elevation, underground obstacle, stratum bearing capacity, and soil resistivity are obtained from the survey data management table. These category codes are bound to the survey equipment type and result file type when the survey task is established. The surface elevation category corresponds to RTK or total station elevation results, and the underground obstacle category... Corresponding to ground-penetrating radar or pipeline detection results, the stratum bearing capacity category corresponds to drilling, in-situ testing, and foundation bearing capacity evaluation results; the soil resistivity category corresponds to the four-electrode resistivity test results. Surface elevation category identifiers are assigned to elevation requirement sections, underground obstacle category identifiers to obstacle requirement sections, stratum bearing capacity category identifiers to bearing capacity requirement sections, and soil resistivity category identifiers to resistivity requirement sections. These category identifiers are taken solely from the category codes already established in the survey data management table, without any manual scoring or weighted combinations. Each requirement section is associated with the construction... The system associates object identifiers, construction area identifiers, construction drawing versions, planar boundaries, top elevations, and bottom elevations. The same construction area can be associated with different categories of requirement sections. For example, a foundation construction area can be associated with elevation requirement sections, obstacle requirement sections, and load-bearing requirement sections simultaneously; a grounding construction area can be associated with elevation requirement sections, obstacle requirement sections, and resistivity requirement sections simultaneously. In this embodiment, foundation construction areas generate foundation elevation requirement records, foundation obstacle requirement records, and foundation load-bearing requirement records; cable line construction areas generate line elevation requirement records and line obstacle requirement records; and grounding construction areas generate grounding elevation requirement records, grounding obstacle requirement records, and grounding resistivity requirement records. After association is completed, it checks whether each construction area has a category identifier that matches its construction method. If a foundation construction area lacks a load-bearing category, any underground construction area lacks an obstacle category, or a grounding construction area lacks a resistivity category, the corresponding construction area is added to the category supplementation record. When the categories are complete, spatial overlay processing is performed, thereby maintaining a clear correspondence between construction objects, construction spaces, and survey categories.

[0092] The survey requirement sections and survey attribution units with the same survey category identifier are spatially overlaid. The survey requirement sections are divided at the intersection of the coverage boundaries and the end face of the survey depth to form corresponding spatial segments. Specifically, the survey category identifier, plane coverage boundary, survey start depth, survey end depth, and source record identifier are obtained from the survey attribution unit. Only survey requirement sections with the same category identifier and survey attribution units are combined into overlay objects. In this embodiment, the surface elevation attribution unit covers the entire construction site, the underground obstacle attribution unit covers the surface projection range of the foundation, cable lines, and grounding facilities, with a survey depth of 2m below the surface, the stratum bearing capacity attribution unit covers the projection range of the foundation bottom surface and extends to 1.1m below the foundation bottom surface, and the soil resistivity attribution unit covers the grounding layout area from 11.5m to 15m on the horizontal coordinate, with a survey depth of 3.5m below the surface. Boundary division is performed on each group of overlay objects. First, the plane coverage boundary of the survey attribution unit intersects with the plane boundary of the requirement section to form an intersection point. Then, adjacent intersection points are divided along the original edge. The boundary sequence is connected to form a dividing line. Then, a vertical dividing plane is established along the dividing line, traversing the demand section. The starting and ending depth faces of the survey unit are used as horizontal dividing planes. The demand section is divided into spatial segments with non-crossing boundaries according to the vertical and horizontal dividing planes. Each spatial segment retains its corresponding construction object, demand category, top elevation, bottom elevation, and the identifier of the intersecting survey unit, forming the corresponding spatial segment. Taking the grounding barrier demand section as an example, the grounding trench is located 0 meters below the ground surface. Within 0.8m, it was not cut off by the 2m survey depth end face. The grounding electrode burial space extends from the bottom of the trench to 3.3m below the ground surface. At the survey termination depth end face 2m below the ground surface, it is divided into upper space segment and lower space segment. Taking the grounding resistivity demand section as an example, the resistivity coverage boundary at 15m on the horizontal axis divides the horizontal grounding trench into space segment inside the boundary and space segment outside the boundary. Thus, the insufficient planar coverage and insufficient vertical survey are respectively assigned to the corresponding space segments with clear spatial boundaries.

[0093] The spatial segments to be matched, located within the coverage boundary and depth range of the survey unit, are formed into survey coverage sections. The remaining spatial segments are merged according to spatial continuity to form survey gaps, generating spatial correspondence records between the construction area and the survey unit. Specifically, the category identifier, planar boundary, and vertical range of each spatial segment to be matched are verified sequentially. If the category identifier matches the survey unit, all planar boundaries are within the coverage boundary of the survey unit, and both the top and bottom are within the survey depth range, then the spatial segment to be matched is associated with the survey unit to form a survey coverage section. If any one of these conditions is not met, the spatial segment to be matched is removed from the survey coverage area. The segments are classified as uncovered spatial segments. These uncovered spatial segments are categorized according to the construction object and survey type. Adjacent segments sharing a non-zero area boundary in 3D space are merged, as are adjacent segments sharing a non-zero length boundary in surface space. The merged continuous space forms a survey gap, while spatially separated uncovered spatial segments are retained as independent survey gaps. In this embodiment, the surface elevation unit covers the entire surface projection of the three construction areas, and all elevation requirement sections form survey coverage sections. The coverage boundary and survey depth of the stratigraphic bearing capacity unit include the foundation bearing capacity requirement section. The survey coverage area was formed; the survey depth of the underground obstacle attribution unit only reached 2m below the surface. The lower space segments from 2m to 3.3m below the surface for the two grounding electrodes were not covered, and these two lower space segments were not connected, forming grounding electrode obstacle survey gaps. Based on a borehole radius of 0.075m and a missing depth of 1.3m, the total volume of the two gaps is approximately 0.046m³. The soil resistivity attribution unit terminates at 15m on the horizontal axis. The 1m grounding trench within the range of 15m to 16m on the horizontal axis forms a resistivity survey gap of 0.4m³. The grounding electrode burial space at 16m on the horizontal axis forms approximately 0.044m. The resistivity survey gap is 3; the survey coverage section and the survey gap are associated with the construction object, demand category, spatial boundary, survey depth and source record identifier respectively, to generate a spatial correspondence record between the construction area and the survey belonging unit, and the boundary of the obstacle survey gap and the resistivity survey gap is used as the layout range of subsequent supplementary surveys; when the processing method of only judging the intersection of plane projection is adopted, the above-mentioned deep gap of the grounding electrode will be recorded as covered. After the plane boundary and survey depth are jointly segmented in this embodiment, the deep gap can be retained, thereby completing the closed-loop processing of demand section division, category association, 3D segmentation, coverage determination and supplementary survey triggering.

[0094] The present invention is further configured such that the formation of the construction conflict record includes:

[0095] Based on the obstacle spatial boundary and construction safety clearance corresponding to the obstacle category in the underground obstacle survey and attribution unit, an underground obstacle protection area is formed by expanding outward along the obstacle spatial boundary, and the outer edge of the underground obstacle protection area is taken as the underground obstacle protection boundary. Specifically, the aforementioned 30m long and 20m wide DC charging station construction site is selected, and the underground obstacle survey and attribution unit, obstacle category safety clearance table, and the three types of construction occupancy already constructed are taken as the processing objects. Underground obstacle data is collected using 400MHz ground penetrating radar with a survey line spacing of 0.8m. One detection record is formed every 0.05m along the survey line, and the survey depth reaches 2m below the ground surface. The obstacle interpretation results are imported through the GeoJSON interface, and the construction occupancy and site construction boundary are imported through the IFC and DXF interfaces. Underground obstacle survey and attribution units with complete source record identification, continuous radar profile, and closed spatial boundaries are retained. Duplicate boundary points are deleted, and adjacent boundary points with a spacing of no more than 0.02m are merged into the same boundary node, and the obstacle boundaries are uniformly converted to the site coordinate system. In this embodiment, the horizontal coordinate is 9m to 15m, the vertical coordinate is 9.6m, and the horizontal coordinate is 9m to 15m. A 0.22m outer diameter existing water supply pipeline was identified at a position 0.9m below the radar line. Pipeline cross-sections were fitted along the echo points at the top and sides of the pipeline, and then the corresponding cross-sections were connected along adjacent lines to form a cylindrical obstacle space boundary. A 0.6m construction safety clearance was obtained from the underground pipeline protection table confirmed by the pipeline owner. This table specifies a clearance range of 0.5m to 1.0m for mechanical excavation at this site, with 0.6m corresponding to the current pipeline type and excavation method. Adding half the pipeline's outer diameter (0.11m) to the 0.6m safety clearance yields... With a protection radius of 0.71m, a circular cross-section with a radius of 0.71m is continuously unfolded with the pipeline centerline as the axis, and the two ends of the pipeline are extended by 0.6m along the centerline direction to form an underground obstacle protection zone. The cylindrical side and the closed surfaces at both ends of this protection zone are used as the underground obstacle protection boundary. The same processing rules are used to call the corresponding values ​​in the safety clearance table for other obstacle categories, so that the protection zone retains the actual size of the obstacle, obstacle category, safety clearance, and source record identification at the same time, avoiding the judgment of construction conflict based solely on the pipeline centerline or the outer edge of the entity.

[0096] Based on the spatial boundaries and bearing capacity of the stratigraphic bearing capacity units, spatially continuous stratigraphic bearing capacity units with the same bearing capacity are merged to form bearing capacity zones. Specifically, spatial boundaries, stratigraphic depths, foundation bearing capacity characteristic values, and source record identifiers are obtained from the stratigraphic bearing capacity survey units. The stratigraphic bearing capacity data comes from approved geotechnical engineering investigation reports. Borehole data is imported via an XML interface according to the report version. In-situ test data is recorded at 0.2m depth intervals. The foundation design documents stipulate that the design bearing capacity characteristic value shall not be lower than 160kPa. The plane coordinates and elevations are converted to the site coordinate system. Records exceeding the effective test depth of the boreholes are eliminated. Records that are adjacent vertically within the same stratigraphic layer and have the same bearing capacity characteristic value are connected to form vertical stratigraphic segments. The underground space of the site is then divided by the stratigraphic boundary line between adjacent boreholes to form stratigraphic bearing capacity units with closed planar and vertical boundaries. Units with a bearing characteristic value of not less than 160 kPa are configured as meeting the bearing requirements, while units with a bearing characteristic value less than 160 kPa are configured as insufficient bearing units. In this embodiment, the bearing characteristic values ​​of two adjacent strata bearing units on the west side of the foundation are 170 kPa and 175 kPa, respectively. Both meet the bearing requirements and the two spatial boundaries share a boundary surface with an area. Therefore, the shared boundary is deleted and the outer edges of the two units are connected to form a zone that meets the bearing requirements. The bearing characteristic value of the strata bearing unit on the east side of the foundation is 145 kPa, which is insufficient bearing. It retains an independent boundary with the zone that meets the bearing requirements, forming a zone that is insufficient bearing. Units that only contact each other at points or on edges are not merged. Adjacent units with different bearing levels retain their original interfaces, thereby forming a bearing zone that can be directly traced back to the borehole record, stratum depth, and bearing characteristic value.

[0097] The foundation construction area is superimposed with the underground obstacle protection area and the load-bearing zone. The cable line construction area and the grounding construction area are superimposed with the underground obstacle protection area and the site construction boundary. The corresponding construction areas are divided along the underground obstacle protection boundary, the load-bearing zone boundary and the site construction boundary to form construction space segments associated with the construction object. Specifically, the foundation construction area is placed in the same site coordinate system as the underground obstacle protection area and the load-bearing zone. The cable line construction area and the grounding construction area are placed in the same site coordinate system as the underground obstacle protection area and the site construction boundary. The site construction boundary is taken from the approved overall construction plan. In this embodiment, a localized inward boundary is formed in the area where the grounding facility is located due to fire lane restrictions. This boundary is closed along the horizontal axis from 10.5m to 11.5m in the vertical coordinate range. When overlaying the foundation construction area and the underground obstacle protection area, the intersection point of the foundation construction area boundary and the obstacle protection boundary is determined. A tangent line is formed by connecting the intersection points, and then a vertical tangent plane is established along the tangent line, dividing the foundation construction area into a section within the protection area and a section outside the protection area. When the construction area and the load-bearing zone are overlaid, the boundary of the load-bearing zone is extended from the bottom of the foundation upwards to the ground surface to form a load-bearing dividing surface. This dividing surface is used to divide the foundation construction area, and the divided sections are associated with the load-bearing zones below the foundation bottom. In this embodiment, the boundary of the insufficient load-bearing zone cuts into the projection of the foundation bottom surface. Along the intersection of the boundaries, the cut-in portion is decomposed into triangles and quadrilaterals. The area of ​​the triangle is calculated based on its base and corresponding height, and the area of ​​the quadrilateral is calculated based on its side length. The resulting areas are then added together to obtain the area corresponding to the insufficient load-bearing zone, which is 0.34 m². (Regarding electricity...) The same boundary intersection generation, split line connection, and vertical splitting process are applied to the cable line construction area and the grounding construction area. Specifically, the section of the grounding trench with an abscissa of 15.5m to 16m and the grounding electrode burial space at the abscissa of 16m are split outside the site construction boundary. Each split section is associated with the construction object identifier, section boundary, obstacle protection area ownership status, load-bearing zoning level, site boundary ownership status, and constraint boundary source to form a construction space section, so that each section corresponds only to a continuous construction space that does not cross the constraint boundary.

[0098] Construction space sections that enter the underground obstacle protection zone, are located outside the site construction boundary, or have a corresponding load-bearing capacity lower than the foundation design load-bearing capacity are designated as conflict space sections. These conflict space sections are associated with the construction object, conflict category, and source of constraint boundary to generate construction conflict records. Specifically, the obstacle protection zone ownership status, site boundary ownership status, and load-bearing capacity of the construction space section are verified sequentially. Sections entering the underground obstacle protection zone are designated as underground obstacle conflict space sections, and sections located outside the site construction boundary are designated as site boundary crossing conflict space sections. Sections below the foundation with a bearing capacity characteristic value lower than 160 kPa are designated as insufficient bearing capacity conflict zones. In this embodiment, the minimum horizontal distance between the centerline of the water supply pipeline and the foundation excavation boundary is 0.303 m. After deducting the pipeline's outer radius of 0.11 m, the remaining net distance is 0.193 m, which is lower than the construction safety net distance of 0.6 m, thus forming a foundation underground obstacle conflict record. The foundation bearing capacity characteristic value corresponding to the 0.34 m² area on the foundation bottom surface is 145 kPa, which is lower than the foundation design bearing capacity characteristic value of 160 kPa, thus forming a foundation insufficient bearing capacity conflict record. The grounding trench, located outside the site construction boundary, is 0.5m long. Combined with its 0.5m width and 0.8m depth, this creates a 0.2m³ boundary-crossing trench space. This space is then merged with the grounding electrode burial space located at 16m (horizontal coordinate), with a volume of approximately 0.0442m³, forming a grounding boundary-crossing conflict space segment of approximately 0.2442m³. This conflict space segment is then compared with the following: foundation construction object or grounding construction object; underground obstacle conflict category; insufficient load-bearing capacity conflict category or site boundary-crossing conflict category; pipeline protection boundary source; load-bearing zoning source or site construction boundary. The drawing version is associated, and the following conflict records are generated sequentially: underground obstacle conflict record, insufficient foundation bearing capacity conflict record, and grounding boundary crossing conflict record. Manual verification is performed along the cross section of the water supply pipeline, the bottom surface of the foundation, and the site construction boundary. When the clear distance, bearing capacity characteristic value, and boundary crossing length obtained from the verification are consistent with the conflict record, the construction conflict record is transferred to the candidate adjustment parameter generation step. If there is inconsistency, the process returns to the corresponding obstacle boundary, bearing capacity zone, or site construction boundary for re-division, thus forming a closed-loop process of obstacle protection area construction, bearing capacity zone merging, construction area division, conflict determination, and boundary verification.

[0099] The present invention is further configured such that, for the conflicting object, generating candidate adjustment parameters within the range of equipment installation dimensions, standard material specifications, and workable locations includes:

[0100] The conflict space segment, constraint boundary source, and construction object are associated. Parameter adjustment directions are formed according to whether the construction is located away from the obstacle protection area, inside the site construction boundary, or within a load-bearing zone with a load-bearing capacity not lower than the foundation design load-bearing capacity. The area of ​​the site's constructable location is then reduced by the obstacle protection area to form candidate construction areas. Specifically, the aforementioned underground obstacle conflict records, insufficient foundation load-bearing capacity conflict records, and underground obstacle conflict records are selected as processing objects. The conflict space segment, construction object identifier, constraint boundary source, and current positioning benchmark are obtained from the conflict records. The site construction boundary, fire lane boundary, and design load-bearing capacity are obtained through the DXF interface. For reserved areas, foundation installation dimensions are obtained from equipment installation drawings, and cable outer diameter, minimum bending radius, and trench cross-sectional dimensions are obtained from material specifications. Static drawings and specification data are re-imported when the approved version changes. Construction object positioning data is re-measured for 5 seconds at a frequency of 2Hz using RTK equipment, retaining only fixed solution records with continuous coordinate changes not exceeding 0.02m. Boundaries from different sources are unified to the site coordinate system, and boundary lines with closed endpoint spacing not exceeding 0.02m are deleted. Conflict records without construction object identification or unconstrained boundary sources are deleted. For foundation construction areas entering the obstacle protection zone, the distance from the conflict space section is calculated. The nearest obstacle protection boundary point is used as the reference point, and the adjustment direction extends outward from the protection area, forming a direction away from the obstacle protection area. For foundation construction areas entering insufficient load-bearing zones, the adjustment direction extends from the conflict section at the foundation bottom to the nearest qualified load-bearing zone, forming a direction for entering the qualified load-bearing zone. For construction areas exceeding the site construction boundary, the adjustment direction extends from the boundary-crossing section to the nearest site construction boundary point, and continues inward, forming a direction for entering the site construction boundary. When there are two types of conflicts for the same construction object, the adjustment direction formed by each type of conflict is retained, and the adjustment direction is changed simultaneously along both directions. The direction of the combination adjustment of position coordinates is removed, and the direction that would increase other conflicting spatial sections is deleted. In this embodiment, the water supply pipeline protection area is located on the north side of the foundation, and the insufficient bearing area is located on the east side of the foundation, thus forming the direction of decreasing vertical coordinate, decreasing horizontal coordinate, and decreasing both horizontal and vertical coordinates. The space defined by the site construction boundary is deducted from the fire lane, equipment reserved area, and underground obstacle protection area, and the usable space is cut off according to the construction depth of the foundation, cable trench, and grounding trench, forming the candidate construction area corresponding to the construction object. The candidate construction area represents the site area that has excluded the explicitly prohibited construction space and still maintains spatial continuity.

[0101] The area within the qualified bearing capacity zone of the candidate construction area is designated as the candidate foundation layout area. This area is then narrowed inwards according to equipment installation dimensions and foundation excavation boundaries to form a centrally located area suitable for foundation placement. The intersection of the foundation adjustment line (formed along the parameter adjustment direction) and this centrally located area is designated as the candidate foundation location. Specifically, a space with a bearing capacity characteristic value not less than 160 kPa below the foundation bottom surface is reserved within the candidate construction area. The surface projection of this reserved space is designated as the candidate foundation layout area. The candidate foundation layout area represents the site area capable of accommodating the foundation excavation range where the foundation bottom surface is located within the qualified bearing capacity zone. The deployable area of ​​the foundation center indicates that when the foundation center falls within it, neither the complete foundation plane positioning boundary nor the foundation excavation operation boundary will exceed the center position range of the candidate foundation deployment area. When forming the deployable area of ​​the foundation center, keeping the charging pile installation direction unchanged, calculate the lateral and longitudinal distances from the foundation center to each vertex of the foundation plane positioning boundary and the foundation excavation operation boundary. Then, move the corresponding distance inward along each boundary of the candidate foundation deployment area. Extend the intersection of adjacent inward-moved boundaries to form the deployable area of ​​the foundation center using the connected inward-moved boundaries. In this embodiment, the foundation excavation operation boundary is 2.4m long and 1.7m wide, following the predetermined installation direction. After conversion, the lateral distance from the foundation center to the farthest vertex of the excavation operation boundary is 1.453m, and the longitudinal distance is 1.297m. The farthest distance of the foundation entity boundary relative to the foundation center in the direction of increasing lateral coordinate is 0.917m. The southern boundary of the water supply pipeline protection area is located at a longitudinal coordinate of 8.89m, therefore the longitudinal coordinate of the foundation center must not exceed 7.593m. The boundary between the qualified bearing zone and the insufficient bearing zone is located at a lateral coordinate of 12.4m, therefore the lateral coordinate of the foundation center must not exceed 11.483m. Taking the 0.02m allowable deviation for layout specified in the construction surveying plan as the boundary allowance, 0.02m is subtracted from the above lateral and longitudinal coordinate limits respectively to obtain... The foundation center can be arranged in an area with an abscissa not greater than 11.463m and an ordinate not greater than 7.573m. The foundation adjustment line is extended from the original foundation center with an abscissa of 12m and an ordinate of 8m along three parameter adjustment directions. The adjustment line with the ordinate decreasing direction still overlaps with the area with insufficient bearing capacity, and the adjustment line with the abscissa decreasing direction still overlaps with the obstacle protection area. The adjustment line with both abscissa and ordinate decreasing simultaneously enters the foundation center can be arranged in an area. The abscissa of the first entry position of this line with an abscissa of 11.463m and an ordinate of 7.573m is taken as the candidate foundation position. The candidate position is directly defined by the obstacle protection boundary, the bearing zone boundary, the equipment installation size and the excavation operation size.

[0102] The spatially continuous areas within the candidate construction zone are used as candidate channels for the cable line and grounding. Keeping the cable line endpoints and grounding electrode connection endpoints unchanged, candidate laying paths are formed by connecting the boundary turning points of the candidate channels according to spatial continuity. Candidate laying paths that do not meet the laying conditions are eliminated based on the minimum bending radius and laying cross-section corresponding to standard material specifications. Specifically, for underground obstacle conflicts, the candidate construction zone is divided into continuous areas that do not cross obstacle protection zones or site construction boundaries. Continuous areas that can simultaneously connect two endpoints of the line are used as candidate channels for the line, and areas that can connect the grounding down conductor endpoint and the grounding electrode connection endpoint are also considered. The continuous area is used as a candidate grounding channel, which represents the construction space that allows the trench cross-section to be continuously expanded. Keeping the power supply side endpoint and the equipment side endpoint unchanged, the location where the boundary direction of the candidate channel changes is taken as the boundary turning point. The boundary turning points are arranged in spatial order from the power supply side endpoint to the equipment side endpoint, and the endpoints and boundary turning points are connected sequentially to form the initial candidate laying path. In this embodiment, the horizontal and vertical coordinates of the power supply side endpoint of another cable line are 4m and 9.6m, and the horizontal and vertical coordinates of the equipment side endpoint are 18m and 9.6m. The outer boundary of the water supply pipeline protection area covers an area with a horizontal coordinate of 8.4m to 15.6m and a vertical coordinate of 8.89m to 1... 0.31m; Obtain a trench width of 0.6m from the cable trench construction details. Extend the outer boundary of the obstacle protection area outward by half the trench width, i.e., 0.3m, to obtain an area where the line center cannot enter, with horizontal coordinates from 8.1m to 15.9m and vertical coordinates from 8.59m to 10.61m. Connect the boundary turning points with horizontal and vertical coordinates of 8m and 8.5m, and 16m and 8.5m along the south side of this area to form a candidate laying path on the south side. Connect the boundary turning points with horizontal and vertical coordinates of 8m and 10.7m, and 16m and 10.7m along the north side of this area to form a candidate laying path on the north side. Obtain a minimum of 0.9m from the cable manufacturer's specification sheet. The bending radius is determined by obtaining a 0.6m wide and 0.8m deep laying cross-section from the cable trench construction details. Adjacent straight road segments are connected at the turning points of candidate laying paths with a radius of 0.9m. Paths are deleted when the turning point cannot accommodate a 0.9m connection range, the trench cross-section extends beyond the candidate channel, or the candidate path intersects itself. In this embodiment, both candidate paths can accommodate a 0.9m turning connection range. A 0.09m gap is maintained between the outer edge of the trench and the protection area on the south path, and a 0.09m gap is maintained between the outer edge of the trench and the protection area on the north path. Therefore, two candidate laying paths are retained, ensuring that path selection is based on actual material bending limitations and trench construction dimensions.

[0103] The candidate foundation locations or candidate laying paths are associated with the corresponding positioning locations, line control points, laying paths, and material specifications to the construction object to generate candidate adjustment parameters. Specifically, the candidate foundation locations are associated with the foundation construction object, the original foundation location, the installation direction, the foundation plan dimensions, the excavation operation dimensions, and the corresponding conflict records to form foundation candidate adjustment parameters. The south and north candidate laying paths are associated with the cable line construction object, line endpoints, path control points, cable material specifications, minimum bending radius, trench width, trench depth, and the corresponding conflict records to form line candidate adjustment parameters. Among them, the positioning location represents the coordinates of the candidate foundation center in the site coordinate system, the line control points represent the endpoints, boundary turning points, and turning connection points in the candidate path, the laying path represents the continuous line formed by connecting the line control points according to the laying sequence, and the material specifications represent the material models corresponding to the trench cross-section and bending limits in the construction drawings and manufacturer specification tables. The position of the foundation candidate adjustment parameters is verified by setting the horizontal coordinate to 11.463m and the vertical coordinate to 7.573m. Substituting the candidate foundation positions of m into the foundation boundary transformation process, a 0.02m interval is maintained between the north side of the foundation excavation operation boundary and the water supply pipeline protection area, and a 0.02m interval is maintained between the east side of the foundation entity and the insufficient bearing capacity zone. The 0.193m pipeline construction clearance corresponding to the original foundation position is increased to no less than 0.6m, and the overlap between the foundation bottom surface and the 145kPa insufficient bearing capacity zone is eliminated. Path verification is performed on the candidate adjustment parameters of the route. A trench section with a width of 0.6m and a depth of 0.8m is continuously arranged along each candidate path. Candidate adjustment parameters are retained when the trench section does not enter the obstacle protection area, does not exceed the site construction boundary, and has a turning radius of no less than 0.9m. If any condition is not met, the candidate channel is returned to reconnect the boundary turning position. The verified candidate foundation adjustment parameters and route adjustment parameters are transferred to the candidate construction area reconstruction step, so that each candidate parameter has a conflict source, adjustment direction, spatial location, material specifications, and verification result, completing the closed-loop processing of construction conflict association, adjustment direction formation, candidate area shrinkage, path screening, and parameter generation.

[0104] The present invention is further configured such that, in the reconstructing of the candidate construction area, the area newly added to the candidate construction area relative to the current construction area is taken as the incremental area, includes:

[0105] Replace the current construction parameters of the corresponding construction object with the candidate foundation location or candidate laying path in the candidate adjustment parameters. Reconstruct the geometric boundary of the corresponding construction object according to the replaced foundation plane positioning boundary, line control point or laying path to generate candidate construction areas. Specifically, select the aforementioned candidate foundation location with horizontal coordinate 11.463m and vertical coordinate 7.573m, as well as the candidate laying paths on the south and north sides, as candidate adjustment parameters. Obtain the current construction area through the IFC interface, and obtain the construction object identifier, candidate positioning location, line control point, laying path and material specifications through the candidate adjustment parameter record. Obtain the foundation through the DXF interface. Planar dimensions, trench cross-sectional dimensions, and construction drawing version; the above data are imported when candidate adjustment parameters are generated or the construction drawing version changes. RTK equipment is used to continuously remeasure candidate foundation positions for 5 seconds at a frequency of 2Hz, retaining only fixed solution records where coordinate changes are no greater than 0.02m. Coordinates from different sources are unified to the site coordinate system, length units are unified to meters, and duplicate model nodes with a distance no greater than 0.001m are merged. 0.001m is taken from the millimeter-level coordinate accuracy of the construction model. Reconstruction stops when candidate adjustment parameters are inconsistent with the construction object identifier or construction drawing version. For the foundation construction object, the current foundation center x-coordinate is set to 12. The vertical coordinate 8m is replaced with the horizontal coordinate 11.463m and the vertical coordinate 7.573m of the candidate foundation center. The installation direction, standard foundation outline, 0.4m excavation clearance, and 1.2m construction depth remain unchanged. The foundation plane positioning boundary is re-established according to the apex of the standard foundation outline, the installation direction, and the candidate foundation center. Then, the foundation plane positioning boundary is extended outward by 0.4m to form the candidate foundation excavation operation boundary. The vertical space is closed by the site surface and the bottom elevation of the candidate foundation, forming the candidate foundation construction area. For cable line construction objects, the current line reference path is replaced with the candidate laying path on the south or north side, respectively, maintaining the line... With the road endpoints, trench width of 0.6m, trench depth of 0.8m, and minimum bending radius of 0.9m unchanged, the line endpoints, candidate control points, and turning connection positions are connected sequentially. The trench cross-section is continuously expanded along the connected path, and the overlapping space of the turning positions is merged to form the candidate cable line construction area on the south side and the candidate cable line construction area on the north side, respectively. The boundary closure status, cross-sectional dimensions, and spatial connection status of the candidate construction area are checked. If the boundary is not closed, the trench cross-sectional dimensions are insufficient, or the turning position is disconnected, the corresponding candidate adjustment parameters are returned to rebuild the candidate construction area to completely preserve the geometric relationship between the candidate position, candidate path, and construction dimensions.

[0106] The candidate construction area is spatially overlaid with the current construction area, and the two are divided at their boundary intersection to form spatial segments. Specifically, candidate construction areas and current construction areas are paired according to the construction object identifier. The foundation candidate construction area is overlaid only with the current foundation construction area, and each candidate cable line construction area is overlaid only with the current cable line construction area to avoid the boundaries of different construction objects participating in the same division process. The intersection points of the candidate construction area boundary line and the current construction area surface, the intersection points of the candidate construction area surface and the current construction area boundary line, and the overlapping edge segments of the two area surfaces are obtained sequentially. Adjacent intersection points with a spacing of no more than 0.001m are merged into the same division node, and then connected according to the order of the intersection points on the original boundary line to form the boundary intersection line. The candidate construction area is divided into segments using the boundary intersection line. Select the intersecting surfaces of the selected construction area and the current construction area. Leave the original surfaces that do not intersect with the boundary line unchanged. Reconnect the cut surfaces according to the cutting nodes to form a closed surface. For overlapping surfaces in the same plane, arrange all boundary nodes of the two surfaces according to their coordinate positions. Insert cutting nodes at the boundary intersection and then form non-crossing surface segments along their respective boundary directions. Connect adjacent surface segments layer by layer according to shared edge lines. When the surface segments enclose a closed space, they form an occupation space segment. This occupation space segment represents the smallest closed space unit formed by the candidate construction area and the current construction area after being cut by a common boundary. Surface segments that fail to form a closed space are returned to the boundary line generation process for reprocessing, ensuring that subsequent new area determinations are based on closed space segments with clear internal and external relationships.

[0107] Space segments located within the candidate construction area and outside the current construction area are designated as new space segments. New space segments belonging to the same construction object and spatially continuous are merged to form incremental areas. Specifically, within each space segment, a check point not located on the boundary line is selected. A check line is extended from this check point along the increasing direction of the site's horizontal coordinate. The number of times the check line crosses the boundaries of the candidate and current construction areas is recorded sequentially. When the check line passes a boundary node, the check point is moved 0.001m along the vertical coordinate direction and re-verified. When the number of times the check line crosses the boundary of the candidate construction area is odd, the segment corresponding to the check point is marked as being inside the candidate construction area; when the number of times it crosses the boundary of the current construction area is even, the segment is marked as being outside the current construction area. Space segments satisfying both conditions are designated as new space segments. New space segments belonging to the same construction object, corresponding to the same candidate adjustment parameter, and sharing a boundary surface with area are merged. New space segments sharing only the edge line or boundary point remain separate, forming one or more incremental areas. The incremental area represents the candidate construction area. The location represents a newly occupied space relative to the current construction location, requiring a re-performance of survey and coverage verification. In this embodiment, the candidate foundation center moves 0.671m longitudinally and 0.142m laterally relative to the current foundation center. The longitudinal dimension of the foundation excavation operation boundary is 2.4m, and the lateral dimension is 1.7m. Subtracting 0.671m from 2.4m yields a longitudinal overlap dimension of 1.729m, and subtracting 0.142m from 1.7m yields a lateral overlap dimension of 1.558m. Multiplying these two overlap dimensions gives approximately 2.694m². The planar overlap area is calculated. Multiplying 2.694 m² by the 1.2 m construction depth yields a common area volume of approximately 3.233 m³. Subtracting the common area volume from the total candidate foundation construction area volume of 4.896 m³ yields an incremental foundation area of ​​approximately 1.663 m³. The same boundary segmentation, internal / external determination, and continuous segment merging process is applied to the candidate cable line construction areas on the south and north sides to form incremental line areas corresponding to the two candidate laying paths. This excludes overlapping portions of the candidate construction areas that already have surveyed and covered foundations from the incremental areas.

[0108] The incremental domain is associated with candidate adjustment parameters, construction objects, candidate construction domains, and the current construction domain to generate incremental domain records. Specifically, each incremental domain is associated with candidate adjustment parameter identifiers, construction object identifiers, candidate construction domain identifiers, current construction domain identifiers, spatial boundaries, top elevations, bottom elevations, and construction drawing versions to form foundation incremental domain records, south side line incremental domain records, and north side line incremental domain records, respectively. The foundation incremental domain record retains the candidate foundation location's x-coordinate of 11.463m, y-coordinate of 7.573m, the current foundation location's x-coordinate of 12m, y-coordinate of 8m, and approximately 1.663m³ of newly added space. The line incremental domain record retains the corresponding candidate path's endpoints, turning control points, trench cross-sections, and newly added spatial boundaries, enabling subsequent survey coverage verification to call up incremental domains according to the candidate adjustment parameters. Cross-sectional verification is performed on the foundation incremental domains, respectively. Horizontal sections are taken at the top, middle, and bottom of the construction area. The newly added area of ​​each section is approximately 1.386 m². Multiplying this area by the 1.2 m construction depth yields approximately 1.663 m³. This is compared with the incremental area volume formed by spatial segmentation. If the difference between the two does not exceed 0.001 m³ corresponding to the accuracy of the construction model, the incremental area record of the foundation is retained. If it exceeds 0.001 m³, the process of boundary intersection segmentation is returned. In this embodiment, the total volume of the candidate foundation construction area is 4.896 m³, and the incremental area volume is approximately 1.663 m³. Compared with using all candidate construction areas as supplementary survey ranges, the space range that needs to be re-verified is reduced by approximately 66.0%. The verified incremental area record is transferred to the overlay step of the same type of survey unit, forming a closed-loop process that connects candidate parameter replacement, construction area reconstruction, common boundary segmentation, new space determination, incremental area verification, and coverage verification.

[0109] The present invention is further configured such that supplementing the survey gap and updating the survey attribution unit includes:

[0110] The incremental area is associated with its corresponding construction object. A category identifier is configured for the incremental area based on the survey requirements of the corresponding construction object, and the incremental area is spatially overlaid with similar survey units. Specifically, the aforementioned incremental foundation area with a volume of approximately 1.663 m³ is selected as the processing object. The construction object identifier, candidate adjustment parameter identifier, plane boundary, top elevation, and bottom elevation are obtained through the incremental area record. The surface elevation, underground obstacles, and stratum bearing capacity survey units are obtained through the survey data interface. The foundation construction depth and the bottom boundary of the foundation design bearing layer are obtained through the construction drawing interface. The incremental area record is imported when the candidate construction area reconstruction is completed, and the survey units are imported when the survey batch is updated. All data is uniformly converted to the site coordinate system. Duplicate boundary nodes with a spacing of no more than 0.001 m are merged, and survey units lacking source record identifiers or survey depths are deleted. According to the survey requirements of the foundation construction object, the projection of the incremental foundation area on the site surface is configured as follows: The surface elevation category is configured as follows: the space from the ground surface to the bottom of the foundation is classified as underground obstacle; the space from the newly covered area of ​​the candidate foundation bottom to the bottom boundary of the foundation design bearing layer is classified as stratum bearing capacity. These categories form foundation incremental elevation demand sections, foundation incremental obstacle demand sections, and foundation incremental bearing capacity demand sections, respectively. Each demand section is spatially superimposed only with the survey unit with the same category identifier. In this embodiment, the surface elevation unit covers the entire site, and all foundation incremental elevation demand sections are located within its coverage area. The original underground obstacle unit and the original stratum bearing capacity unit are arranged according to the current foundation construction area. The newly added space formed after the candidate foundation location is moved southwest exceeds the original survey coverage boundary. The demand section, the corresponding foundation construction object, the candidate foundation location, and the intersecting survey unit are associated so that subsequent supplementary surveys are processed according to the actual missing survey categories, avoiding the repeated inclusion of incremental space with existing elevation coverage in the elevation survey scope.

[0111] The incremental territory is divided along the coverage boundary and depth face of the survey unit. Spatial segments within the coverage area of ​​similar survey units are taken as incremental coverage segments, and the remaining spatial segments are merged according to spatial continuity to form survey gaps. Specifically, the planar coverage boundary of similar survey units intersects with the boundary of the incremental territory. Cutting nodes are inserted at the boundary intersections, and the cutting nodes are connected in the order they appear on the original boundary to form a planar cutting line. A vertical cutting surface is then established along the planar cutting line, penetrating the incremental territory. The survey start depth face and survey end depth face of the survey unit are used as horizontal cutting surfaces. The incremental territory is divided into spatial segments whose boundaries no longer cross the survey coverage area using the vertical and horizontal cutting surfaces. For each spatial segment, the category identifier, planar coverage status, and survey depth are verified. If the categories are the same, the planar boundaries are all within the coverage boundary of the survey unit, and the bottom of the spatial segment does not exceed the survey end depth, then the segment is considered an incremental territory. Spatial segments are designated as incremental coverage areas, while other spatial segments are designated as uncovered spatial segments. Uncovered spatial segments belonging to the same construction object and the same survey category and sharing an area boundary are merged, while spatial segments sharing only the edge line or boundary point remain separate, forming a survey gap. The survey gap represents a continuous space in the incremental domain lacking valid survey data of the corresponding category. In this embodiment, the newly added planar area of ​​the basic incremental domain is formed by connecting a longitudinal strip with a width of 0.671m and a length of 1.7m and a transverse strip with a width of 0.142m and a length of 1.729m. The total planar area of ​​the two strips is approximately 1.386m². The required depth for underground obstacle survey is 1.2m. The original underground obstacle attribution unit does not cover the newly added area, thus forming a basic incremental obstacle survey gap with a volume of approximately 1.663m³. The surface elevation attribution unit completely covers this area, thus the basic incremental elevation requirement segment forms an incremental coverage segment and does not trigger supplementary elevation surveys.

[0112] Starting from one boundary of the survey gap, survey points or lines are sequentially deployed according to the single effective detection range of the survey equipment, ensuring that the effective detection boundaries of adjacent survey points or lines are interconnected, and that the supplementary survey depth is not less than the construction depth of the incremental area. Specifically, for the survey gap of the foundation incremental obstacle, a 400MHz ground-penetrating radar with the same unit as the original underground obstacle survey is selected. The equipment calibration record indicates that the effective lateral detection width of a single survey line under the soil conditions of this site is 0.6m and the effective detection depth is 1.5m. The width was obtained through lateral movement tests using buried metal markers at known locations. The effective detection depth was obtained through continuous identification of the marker burial depth and radar echoes. An effective detection depth of 1.5m is greater than the incremental construction depth of 1.2m. The boundary of the survey gap adjacent to the original underground obstacle survey unit was used as the starting point for deployment. Two survey lines were deployed along a length of 1.7m within a strip 0.671m wide and 1.7m long, ensuring that the distance from the center of each survey line to the edge of the adjacent strip was no greater than 0.3m, and that the effective detection ranges of the two survey lines overlapped. A survey line is laid out along the 1.729m length of a strip 0.142m wide and 1.729m long, with an effective detection width of 0.6m covering both sides of the strip. The starting and ending points of each survey line are extended 0.3m beyond the boundary of the survey gap, with the extension distance taken as half the effective detection width of a single survey line, ensuring that the effective detection range at the end of the survey line covers the end face of the survey gap. The ground-penetrating radar operates at a data acquisition rate of 40 channels per second, retaining one radar record for every 0.05m movement of the encoding wheel, while simultaneously recording data at a frequency of 2Hz using an RTK device. Record the location of the survey line, delete the measurement section whose location deviates from the design survey line by more than 0.02m and re-detect, perform start time correction and invalid channel elimination on the radar record, and convert the detection depth according to the relationship between the propagation time in the calibration record and the known burial depth; after completing 3 survey lines, check whether the effective detection boundary of adjacent survey lines is connected and whether the actual detection depth reaches 1.2m. If there is a lateral discontinuity or insufficient detection depth, add survey lines at the discontinuity or reduce the antenna movement speed to re-acquire data, so that the supplementary survey range matches the plane shape and construction depth of the survey gap;

[0113] The supplementary survey points or lines are linked with the actual detection range to form a supplementary survey cover. When the supplementary survey cover is spatially continuous with similar survey units, it is merged and the coverage boundary, survey depth, and source record association are updated. When the space is discontinuous, a new survey unit is generated based on the supplementary survey cover. Specifically, the actual trajectory of each supplementary survey line is extended 0.3m to both sides to form a planar coverage strip, with the site surface as the top boundary and the actual detection depth of radar records achieving continuous effective echoes as the bottom boundary. The planar coverage strip and the top boundary are connected. The boundary and bottom boundary form a single survey line coverage; the three survey line coverages are spatially superimposed, the shared boundary within the overlapping area is deleted, and the outer boundary and the dividing end face between different detection depths are retained to form a supplementary survey coverage. The supplementary survey coverage represents the closed space composed of the actual planar range, vertical range, and corresponding source records covered by the supplementary survey line; it is checked whether the supplementary survey coverage and the original underground obstacle survey unit share a boundary surface with an area. In this embodiment, the supplementary survey line is continuously laid out from the original survey coverage boundary to the new area, and the supplementary survey coverage and the original underground obstacle Since the survey unit is spatially continuous, the shared boundary between the two is deleted and the external boundary is connected. The depth interface between the original survey area (2m depth) and the supplementary survey area (1.5m depth) is retained. The original source record identifier and the three supplementary survey line records are jointly associated with the updated underground obstacle survey unit. When the supplementary survey cover does not share a boundary with the original survey unit, spatial merging is not performed. A new survey unit is formed by the external boundary of the supplementary survey cover, the actual detection depth, and the supplementary survey line records. The updated underground obstacle survey unit is then reconnected with the basic incremental obstacle. With overlapping demand sections, the 1.386m² newly added planar area in this embodiment is located within the updated coverage boundary, and the 1.2m construction depth does not exceed the actual detection depth of 1.5m. The original 1.663m³ survey gap is completely converted into an incremental coverage section. Compared with the repeated survey of the entire 4.896m³ candidate foundation construction area, this embodiment only conducts supplementary surveys on the 1.663m³ incremental area, reducing the survey verification space by about 66.0%, and forming a closed-loop process of incremental area classification, survey gap segmentation, survey line layout, coverage construction, attribution unit update, and coverage verification.

[0114] The present invention is further configured such that updating the obstacle protection area and bearing capacity zone according to the updated survey attribution unit and verifying the candidate construction area includes:

[0115] Based on the updated underground obstacle attribution units, the obstacle space boundary is re-formed, and the obstacle space boundary is expanded according to the construction safety clearance to form an updated obstacle protection area. The bearing capacity zones are then re-divided based on the updated stratigraphic bearing capacity attribution units. Specifically, the updated underground obstacle survey attribution units and stratigraphic bearing capacity survey attribution units after supplementary surveys are selected as processing objects. Obstacle space records are obtained through the GeoJSON interface, bearing capacity test records are obtained through the geotechnical investigation data interface, and the construction safety clearance and foundation design bearing capacity characteristic values ​​corresponding to the obstacle category are obtained through the construction constraint table. The supplementary underground obstacle survey uses a 400... The MHz ground-penetrating radar acquires data at a rate of 40 channels per second. One radar record is retained for every 0.05m movement of the encoding wheel. Supplementary ground bearing capacity surveys generate one test record every 0.2m along the depth direction. The supplementary survey data is uniformly converted to the site coordinate system. Radar sections deviating more than 0.02m from the design survey line and bearing capacity records exceeding the effective test depth are deleted. Repeated obstacle boundary nodes with a spacing of no more than 0.001m are merged. For each continuous radar anomaly section, the start, peak, and end positions of the anomalous echo are marked along the survey line, and corresponding positions belonging to the same anomaly in adjacent survey lines are connected. An obstacle section is formed, and then adjacent sections are connected along the survey line arrangement direction to form a closed obstacle space boundary. In this embodiment, no new continuous abnormal boundary is formed within the basic incremental occupancy supplementary survey range, and the original water supply pipeline obstacle space boundary remains unchanged. Within the incremental survey range of the candidate cable line on the south side, an abandoned communication trench with a width of 0.3m and a height of 0.2m is identified, with its horizontal coordinate range of 11.6m to 12.8m, vertical coordinate range of 8.35m to 8.65m, and burial depth range of 0.5m to 0.7m. The construction safety clearance of 0.5m for the communication trench is obtained from the construction constraint table, and the six sections of the trench are... The boundary surfaces are moved outward by 0.5m respectively, and the boundary is connected and closed at the junction of adjacent moving surfaces to form a new communication trench protection area; the soil bearing capacity is supplemented and classified according to the 160kPa foundation design bearing capacity characteristic value. The bearing capacity characteristic values ​​of the newly added test locations are 168kPa and 172kPa respectively, both of which are classified as meeting the bearing capacity requirements. They are merged with the original qualified bearing capacity zones of the shared boundary surface, the internal shared boundary is deleted and the external boundary is connected to form a new qualified bearing capacity zone, so that the candidate construction area verification adopts the obstacle boundary and bearing capacity boundary actually formed after the supplementary survey;

[0116] The candidate foundation construction area is spatially overlaid with the updated obstacle protection area and load-bearing zone. The candidate foundation construction area is then segmented along the obstacle protection boundary and the load-bearing zone boundary to form a foundation verification section. Specifically, the first candidate foundation construction area with horizontal and vertical coordinates of 11.463m and 7.573m, and the second candidate foundation construction area with horizontal and vertical coordinates of 11.2m and 7.3m, are spatially overlaid with the updated water supply pipeline protection area, communication trench protection area, and load-bearing zone, respectively. The intersection points of the candidate foundation construction area boundary with the obstacle protection boundary and the load-bearing zone boundary are sequentially obtained. Cutting nodes are inserted at the intersection points, and adjacent cutting nodes on the same constraint boundary are connected to form a cutting line. A vertical cutting surface is then established along the cutting line, penetrating the candidate foundation construction area. For the load-bearing zone, the load-bearing zone boundary is extended from the bottom boundary of the foundation design bearing layer to the site surface. The extended boundary surface is used to segment the candidate foundation construction area, and the segmented foundation bottom surface segment is associated with the load-bearing zone below it. The closed space formed by the segmentation is then... The obstacle protection area is configured with its ownership status, load-bearing level, candidate adjustment parameter identifier, and constraint boundary source to form a basic verification section. The basic verification section represents the candidate foundation space that does not cross any obstacle protection boundary or load-bearing zone boundary. In this embodiment, the first candidate foundation construction area maintains a 0.02m interval with the water supply pipeline protection area and does not enter the newly added communication trench protection area. Its foundation bottom surface is entirely located within the updated qualified load-bearing zone with a load-bearing characteristic value of not less than 160kPa. Therefore, the corresponding basic verification sections all meet the verification conditions. The second candidate foundation construction area also does not enter the updated obstacle protection area, and the foundation bottom surface has a corresponding load-bearing characteristic value of not less than 160kPa. Therefore, the corresponding basic verification sections all meet the verification conditions. The incremental area volume corresponding to the first candidate foundation construction area is approximately 1.663m³, and the incremental area volume corresponding to the second candidate foundation construction area is approximately 2.540m³, obtained from the incremental area record. This provides a unified comparison object for selecting the smaller incremental area from the verification pass parameters.

[0117] The candidate cable line construction area and candidate grounding construction area are spatially overlaid with the updated obstacle protection area and site construction boundary, respectively. The corresponding candidate construction areas are then divided along the obstacle protection boundary and site construction boundary to form line verification sections and grounding verification sections. Specifically, the southern and northern candidate cable line construction areas are spatially overlaid with the updated water supply pipeline protection area, communication trench protection area, and site construction boundary, respectively. The candidate grounding construction area is spatially overlaid with the same constraint boundary. Cutting nodes are inserted at the intersection of the candidate construction area and the obstacle protection boundary or site construction boundary. Cutting nodes are connected according to the extension order of the intersection line on the surface of the candidate construction area to form a closed cutting line. The surface of the candidate construction area is then divided along the closed cutting line, and adjacent surfaces after division are connected according to the shared edge line to form a closed space. The closed space belonging to the cable line construction object is designated as the line verification section, and the closed space belonging to the grounding construction object is designated as... For grounding verification sections, the attribution status of the obstacle protection area, the attribution status of the site boundary, the candidate adjustment parameter identifier, and the source of the constraint boundary are respectively associated. In this embodiment, the candidate laying path on the south side passes through the area with a vertical coordinate of 8.5m. Its 0.6m wide and 0.8m deep trench cross section spatially overlaps with the updated communication trench protection area. The overlapping part forms the line verification section that enters the obstacle protection area. The candidate laying path on the north side is located at a vertical coordinate of 10.7m. Its southern outer edge of the trench maintains a 0.09m interval with the original water supply pipeline protection area and does not enter the newly added communication trench protection area. All line verification sections are located inside the site construction boundary. When the trench space and grounding electrode burial space occupied by the candidate grounding construction area do not enter the updated obstacle protection area and are both located inside the site construction boundary, its corresponding grounding verification section passes the spatial condition verification. Thus, on the basis that the candidate path has avoided the original obstacle, it is possible to continue to identify construction conflicts caused by newly discovered obstacles in the supplementary survey.

[0118] Based on the candidate adjustment parameters, the review sections are categorized as follows: Candidate adjustment parameters for foundations where all foundation review sections do not enter the obstacle protection zone and whose load-bearing capacity is not lower than the foundation design load-bearing capacity; and candidate adjustment parameters for lines or grounding where all line review sections or grounding review sections do not enter the obstacle protection zone and are located within the site construction boundary, are considered as approved candidate adjustment parameters. The candidate adjustment parameter with the smallest corresponding incremental area is selected. Specifically, all review sections formed by the same candidate foundation construction area, candidate cable line construction area, or candidate grounding construction area are categorized according to the candidate adjustment parameter identifier. If any foundation review section corresponding to a candidate adjustment parameter enters the obstacle protection zone or its corresponding load-bearing characteristic value is lower than 160 kPa, that candidate adjustment parameter is listed as a failed review parameter. If all foundation review sections are located outside the obstacle protection zone and their corresponding load-bearing characteristic values ​​are not lower than 160 kPa, they are listed as approved review parameters. If any review section corresponding to a candidate line adjustment parameter or grounding candidate adjustment parameter enters the obstacle protection zone or is located outside the site construction boundary, the corresponding parameter is listed as a failed review parameter. If all verification sections are located outside the obstacle protection area and inside the site construction boundary, they are listed as verification passed parameters. In this embodiment, both the first and second candidate foundation adjustment parameters passed verification. Comparing the incremental volume of the two parameters belonging to the same foundation construction object, the first candidate foundation adjustment parameter with an incremental volume of approximately 1.663 m³ was selected, while the second candidate foundation adjustment parameter with an incremental volume of approximately 2.540 m³ was excluded. The incremental volume corresponding to the candidate line adjustment parameters on the south side is approximately 2.080 m³, but its line verification area... The segment enters the newly added communication trench protection area and therefore does not participate in the volume selection. All the verification segments of the candidate line adjustment parameters on the north side meet the spatial conditions, and their corresponding incremental occupancy of approximately 2.310m³ is retained. The consistency between the candidate adjustment parameter identifier, the number of verification segments, and the incremental occupancy record is verified again. If there are missing segments or association errors, the process returns to the spatial segmentation step. If all associations are consistent, the selected candidate adjustment parameters are transferred to the associated construction parameter update step, thereby avoiding the selection of candidate schemes entering the newly discovered obstacle protection area based solely on the smaller incremental occupancy.

[0119] The present invention is further configured such that updating the associated parameters according to the connection relationship between the foundation location and the cable equipment side endpoint and the grounding down conductor endpoint, and the laying relationship between the cable and the grounding facility, includes:

[0120] When the selected candidate adjustment parameters include the foundation location, the updated foundation location is associated with the charging pile wiring location and the grounding down conductor connection location, respectively. The charging pile wiring location is taken as the cable equipment side endpoint, and the grounding down conductor connection location is taken as the grounding down conductor equipment side endpoint. Specifically, the first candidate foundation adjustment parameter with a verified incremental volume of approximately 1.663m³ is selected. The candidate foundation center's abscissa of 11.463m and ordinate of 7.573m are taken as the updated foundation location. The charging pile equipment installation model is obtained through the IFC interface, and the local positions of the charging pile wiring location and the grounding down conductor connection location relative to the foundation center are obtained through the equipment installation diagram. The updated foundation location is continuously re-measured for 5 seconds at a frequency of 2Hz using an RTK device, retaining only the fixed solution record where the coordinate continuous change is no greater than 0.02m. The equipment installation model, foundation location, and connection location are uniformly converted to the site coordinate system. The candidate foundation center is aligned with the foundation center in the equipment installation model, keeping the charging pile installation direction unchanged. Then, the charging pile wiring location and the grounding down conductor connection location are synchronously translated according to the change in foundation location. The wiring location of the charging pile in this embodiment is located at 0.30m longitudinally positive and 0.15m laterally negative from the center of the foundation in the equipment installation drawing. This local location is converted to the site coordinate system according to the installation direction of the charging pile and superimposed on the center of the candidate foundation to obtain the charging pile wiring location with an abscissa of 11.798m and a ordinate of 7.573m. This location is used as the updated cable equipment side end point. The grounding down conductor connection location is located at 0.25m longitudinally negative and 0.20m laterally positive from the center of the foundation in the equipment installation drawing, using the same coordinate system. The conversion process yields the grounding down conductor connection position with an abscissa of 11.150m and a ordinate of 7.640m, which is used as the updated grounding down conductor equipment side endpoint. The two equipment side endpoints are associated with the candidate foundation adjustment parameter identifier, foundation construction object, equipment installation drawing version, and local position record, respectively. If the difference in the local relative position before and after the endpoint conversion is no greater than 0.02m, the update result is retained. If it exceeds 0.02m, the installation direction and equipment model reference point are returned for verification, so that the cable connection position and grounding connection position change synchronously after the foundation is moved.

[0121] Keeping the cable power supply end point unchanged, the cable equipment end point, candidate line control point, and cable power supply end point are connected to form updated cable line parameters. The trench cross-section is then developed along the updated line reference path to form an updated cable line construction area. Specifically, the cable power supply end point with an abscissa of 2m and ordinate of 4m is obtained from the power supply construction drawing. This end point is kept unchanged. The updated cable equipment end point replaces the original equipment end point. The first line control point with abscissa of 6m and ordinate of 4m and the second line control point with abscissa of 6m and ordinate of 7m are obtained through the verified line candidate adjustment parameters. The cable equipment end point, the first line control point, the second line control point, and the cable equipment end point are connected in the order of their installation. Duplicate line sections with a length not exceeding 0.02m are deleted. At the turning points of adjacent line sections, continuous turning connections are formed according to the minimum bending radius of 0.9m specified in the cable manufacturer's specifications, resulting in the updated line reference path. In this embodiment, the cable power supply end point to the first line... The path length of the control point is 4m, the path length from the first line control point to the second line control point is 3m, and the path length from the second line control point to the cable equipment end point is approximately 5.83m. The total length of the updated line reference path is approximately 12.83m. A trench width of 0.6m and a trench depth of 0.8m are obtained from the cable construction details. The corresponding rectangular trench cross-section is continuously unfolded along the updated line reference path. Adjacent trench cross-sections are connected at turning points, and overlapping spaces are deleted, forming an updated cable line construction area with a volume of approximately 6.16m³. Vertical cross-sections are taken at the two line control points and the cable equipment end point. The updated cable line parameters are retained when the cross-section width is not less than 0.6m, the depth is not less than 0.8m, adjacent cross-sections maintain spatial continuity, and the coordinate difference between the line end point and the charging pile connection position is not greater than 0.02m. If any condition is not met, the connection is reconnected to the candidate line control point, ensuring that changes in the foundation position are transmitted along the equipment end point to the complete cable line.

[0122] Based on the cable and grounding facility laying relationship defined in the construction design, when laying cables in a common trench, the grounding connection conductor laying path is adjusted along the updated line reference path. When laying cables separately, the updated cable line construction area is expanded according to the design clearance. The area enclosed by the site construction boundary is subtracted from the expanded area to form a grounding candidate laying area. Within the grounding candidate laying area, the equipment side endpoint of the grounding down conductor and the grounding electrode connection endpoint are connected to form updated grounding construction parameters. Specifically, the cable and grounding facility laying relationship identifier is obtained from the approved grounding construction drawing. The laying relationship identifier is set to either common trench laying or separate laying. During installation, the grounding connection conductor is placed along the updated baseline path on the designated side of the cable trench, and the elevation of the grounding conductor is adjusted according to the vertical spacing specified in the grounding construction drawing. During separate installation, the updated cable line construction area is extended outwards according to the design clearance to form a grounding restricted area. This embodiment uses separate installation; the construction design specifies a clearance of 0.5m between the cable trench and the grounding trench, which falls within the 0.5m to 1.0m range specified in the project construction design. The installation extends outwards by 0.5m along the horizontal outer edge of the updated cable line construction area, connecting adjacent extension boundaries at turning points. A continuous grounding restricted area is formed by deducting the grounding restricted area, underground obstacle protection area, and equipment reserved area from the area enclosed by the site construction boundary, thus forming a grounding candidate layout area. Keeping the first grounding electrode connection endpoints at coordinates of 12m and 11m, and the second grounding electrode connection endpoints at coordinates of 16m and 11m unchanged, starting from the grounding down conductor equipment side endpoints at coordinates of 11.150m and 7.640m, the turning control points and the two grounding electrode connection endpoints located within the grounding candidate layout area are connected sequentially to form a grounding layout path. A 0.5m wide grounding path is then extended along this path. A 0.8m deep grounding trench section is used to connect two 2.5m long grounding electrode burial spaces with a 0.15m diameter burial hole to the bottom of the trench, forming updated grounding construction parameters. The distance between the outer edge of the grounding trench and the grounding restricted area, the continuity of the grounding layout path, and the connection status of the endpoints are verified. If the outer edge of the trench does not enter the grounding restricted area, the path is continuous, and the coordinate difference of the endpoints on the equipment side of the grounding down conductor is not greater than 0.02m, the updated results are retained. Otherwise, the boundary turning position in the grounding candidate layout area is reselected, so that the grounding facilities are adjusted in relation to changes in the foundation location and cable line.

[0123] Based on the updated basic construction parameters, cable line parameters, and grounding construction parameters, the construction area is reconstructed to form an incremental area. Supplementary surveys are conducted for any survey gaps. When construction conflict records are generated, candidate adjustment parameters are regenerated for the conflicting objects. The process of updating associated parameters, verifying coverage, and comparing areas is repeated until there are no survey gaps and no construction conflict records. Specifically, the basic construction area is reconstructed according to the updated basic location, the cable line construction area is reconstructed according to the updated line reference path, and the grounding construction area is reconstructed according to the updated grounding layout path. The three types of updated construction areas are overlaid with their corresponding pre-update construction areas, and the areas are divided at the boundary intersections while retaining positions. Within the updated construction area but outside the original construction area, spatial segments are used to form incremental foundation areas, incremental line areas, and incremental grounding areas. These incremental areas are overlaid with the survey units for surface elevation, underground obstacles, stratum bearing capacity, or soil resistivity. In this embodiment, after the first associated update, a gap exists in the underground obstacle survey at the turning point of the grounding path with horizontal and vertical coordinates of 10.6m and 9.4m. A 400MHz ground-penetrating radar survey line is laid according to the boundary of this gap. Supplementary surveys identify abandoned concrete structures with horizontal coordinates from 10.4m to 10.9m, vertical coordinates from 9.1m to 9.6m, and burial depths from 0.4m to 0.8m. These structures are then identified according to the construction constraint table. The specified 0.3m safety clearance forms an obstacle protection zone. The updated grounding construction area enters this protection zone and forms a construction conflict record. For this grounding conflict object, a new grounding candidate path is generated. The original turning control point is adjusted to positions with horizontal and vertical coordinates of 9.8m and 9.4m, and connected to the first grounding electrode connection endpoint via the second turning control point with horizontal and vertical coordinates of 11.2m and 10.6m, thus reconstructing the grounding construction area and the incremental grounding area. During the second coverage verification, supplementary surveys were conducted on the underground obstacle survey gaps and soil resistivity survey gaps corresponding to the newly added grounding path. After updating the corresponding survey attribution units, no new obstacle space was identified, and the grounding construction area did not enter the protection zone. The iteration ends when all spatial segments of the incremental domain of the foundation, the incremental domain of the line, and the incremental domain of the grounding are associated with the same type of survey unit, the foundation verification section meets the bearing requirements, and the line verification section and the grounding verification section have not entered the obstacle protection area and are located inside the site construction boundary. Otherwise, candidate adjustment parameters are regenerated according to the conflicting construction objects, and the associated parameter update, incremental domain formation, coverage verification and construction domain comparison are repeated, thus forming a closed loop process of foundation position change to cable endpoint and grounding endpoint, synchronous update of construction path, supplementation of survey gaps and conflict feedback adjustment.
