[0001] This application relates to the field of pavement repair technology, and in particular to a quantity calculation method for pavement repair design after road excavation. Background Technology

[0002] Urban road network renovation, flood control and drainage culvert construction, and underground integrated pipe gallery construction typically require road excavation, followed by road surface repair. These projects involve a large workload in road excavation and repair design, numerous repetitive calculations, low efficiency, and are prone to errors in quantity surveying. Therefore, efficiently and accurately designing road surface repair and calculating related quantities after excavation is a crucial issue.

[0003] In existing technologies, the calculation of road repair quantities mainly relies on manual methods. This method involves repetitive calculations and lacks a systematic, standardized, and efficient design quantity calculation process. It is difficult to adapt to the complexities of different road types and excavation ranges, especially in multi-road networks and long-distance linear projects, where design efficiency is low and errors are prone to occur. Furthermore, the calculation of traffic diversion design quantities is not comprehensive enough and lacks linkage calculation with the road repair plan.

[0004] Therefore, there is an urgent need to develop a standardized and automated method, equipment, and storage device for calculating quantities for municipal road excavation and pavement repair design. Summary of the Invention

[0021] According to a first embodiment of the present invention, the present invention claims protection for a quantity calculation method for road excavation and pavement repair design, referring to... Figure 1 ,include: Obtain the basic data for the pavement repair design of the road to be repaired, and input the relevant parameters of the components and parts to be used in the basic data into the standard group component selection table; The basic data is input into the road segment engineering quantity calculation table according to the road segment division results, and the excavation characteristic parameters of the road to be repaired are determined. Based on the basic data and excavation characteristic parameters of the road to be repaired, and combined with the differences between the road to be repaired and other types of roads, the road repair scope of the road to be repaired is determined. Based on the basic data, excavation characteristic parameters, and road repair range of the road to be repaired, the component parameters in the standard component selection table are called to automatically match the road excavation and pavement repair design schemes for different road sections, and calculate the road excavation and pavement repair design engineering quantity and traffic diversion design engineering quantity. Create a list of road excavation and repair design parameters and a summary table of road excavation and repair quantities, and generate a road excavation and pavement repair design quantity calculation report.

[0022] In this embodiment, the core function of the standard component selection table is to establish a structured parameter library, providing standardized input for subsequent automatic calculation of engineering quantities. Its specific connection logic is as follows: The table predefines road type (asphalt / concrete), standard component parameters (such as surface layer thickness and joint specifications), etc., to form a component parameter database.

[0023] In the "Automatic Matching of Road Repair Design Scheme" step, the system calls the component parameters of the table according to the road segment attributes (such as road grade and road surface type) to dynamically generate a matching scheme, which can be directly used to calculate the road repair work volume (such as the volume of asphalt surface layer and the number of dowel bars); a summary table of support work volume is generated (for example, calling the "traffic diversion component" parameters to calculate the length of the enclosure and the number of signs).

[0024] Furthermore, the step of obtaining basic data for the pavement repair design of the road to be repaired, and inputting the relevant parameters of the components and parts to be used in the basic data into the standard group component selection table, also includes: The basic data for the pavement repair design of the road to be repaired shall include at least the existing road parameters, underground structure design parameters, and standard components. The road status parameters include at least the road grade, design speed, number of lanes, pavement type, pavement width, geological conditions, surrounding environmental conditions, and lane occupancy. The road classification includes expressways, arterial roads, secondary arterial roads, and local roads; The road surface types include asphalt pavement and cement concrete pavement; When the road surface type is cement concrete pavement, it is necessary to obtain the length L of the concrete pavement slab. h Width B h Information such as; The underground structure design parameters include the main structure length L0, the outer contour dimension D0, and the initial burial depth H. q End point burial depth H z1. Thickness of the protective layer of the main structure (B1); 2. Width of the construction working surface of the main structure (B2); 3. Thickness of the structural support (B3); 4. Thickness of the structural foundation (T) jc Structural cushion layer thickness T dc Foundation replacement layer thickness T ht Support method, slope ratio is m; The length L0 of the main structure is determined by the station number and coordinate position information; The standard components include earthwork components, asphalt pavement structure components, cement concrete pavement structure components, and traffic diversion facility components. The earthwork components include filling components and excavation components; The asphalt pavement structural components include asphalt surface layer, tack coat, slurry seal coat, prime coat, stress-absorbing layer, base course, and subbase components; The cement concrete pavement structure components include a concrete surface layer, a base layer, a subbase layer, longitudinal joints, transverse joints, transverse dowel bars, and longitudinal tie rods. The traffic diversion facility components include construction barriers, water-filled barriers, crash barriers, warning lights, traffic signs, and traffic marking components.

[0025] The standard component table includes component model and quantity parameters per unit project.

[0026] In this embodiment, the standard components drive subsequent calculations through a parameterized model, specifically as follows: For calculating the repair work volume, if the road section is an asphalt pavement, use parameters such as "asphalt surface layer thickness" and "unit usage of tack coat" in the table, and calculate the material quantity in combination with the repair range; if it is a cement concrete pavement, use parameters such as "lateral dowel bar spacing" and "longitudinal tie bar length", and calculate the number of components in combination with the repair range of the slab.

[0027] The traffic diversion design uses parameters such as "unit length usage of construction enclosure" and "warning light configuration rules" from the standard component selection table to generate the quantity of diversion facilities, based on the road grade and lane occupancy.

[0028] The summary table is generated by directly filling in summary table fields such as "Project Name" and "Rule Model" (e.g., "Asphalt Surface Layer-AC-16, Unit: m³") with component parameters as the basic data source.

[0029] Furthermore, the step of inputting the basic data into the road segment engineering quantity calculation table based on the road segment division results, and determining the excavation characteristic parameters of the road to be repaired, also includes: Based on basic data, roads with the same or similar road grade, pavement type, design speed, number of lanes, pavement type, pavement width, and roadbed geological conditions in the existing road parameters, and with the same or similar slope conditions in the underground structure design parameters, are considered as a road segment. Based on the slope conditions, the existing road parameters and underground structure design parameters are input into the engineering quantity calculation table for the road section according to the road segment. Based on the outer contour dimensions, burial depth, and support parameters of the underground structure of the road to be repaired, the excavation length, excavation depth, and excavation width of each road section are calculated.

[0030] Furthermore, the calculation of the average excavation length, excavation depth, and excavation width of each road segment based on the outer contour structural dimensions, burial depth, and support type parameters of the underground structure of the road to be repaired also includes: The actual laying length of the underground structure of the pipeline network, culverts, and pipe gallery of the road to be repaired is obtained, and the excavation length of each section of the road to be repaired is calculated by using the underground structure station number and coordinates. The burial depth, foundation thickness, cushion layer thickness, and foundation replacement layer thickness of the underground structure of the road to be repaired are obtained, and the excavation depth of each section of the road to be repaired is calculated. A construction operation space of a predetermined width is reserved on both sides of the underground structure of the road to be repaired. The excavation width of each section of the road to be repaired is calculated based on the thickness of the structural protective layer of the underground structure, the width of the structural construction working face, and the thickness of the structural support.

[0031] In this embodiment, the existing road parameters and underground structure design parameters are input into the road segment engineering quantity calculation table. Roads with the same or similar road grade, pavement type, design speed, number of lanes, pavement type, pavement width, and roadbed geological conditions in the existing road parameters, and roads with the same or similar slope conditions in the underground structure design parameters, are considered as one road segment and input into the road segment engineering quantity calculation table separately. The slope conditions need to be determined in conjunction with geological conditions, burial depth, and the surrounding environment of the proposed excavation location. When the geological conditions are good, the burial depth is less than 5m, and there is safe excavation space, the slope excavation method is adopted, and the slope ratio is m; when the geological conditions are poor, the burial depth is greater than 5m, or the surrounding environment is limited, the excavation and support method is adopted, and m is set to 0. The road segment engineering quantity calculation table includes existing road parameters, underground structure design parameters, road repair range design parameters, earthwork engineering quantity calculation parameters, asphalt pavement repair engineering quantity calculation parameters, cement concrete pavement repair engineering quantity calculation parameters, and traffic diversion engineering quantity calculation parameters. W=D0+2×(B1+B2+B3)+2×m×H; That is, the road excavation width = the outer contour dimension of the underground structure + 2 × (the thickness of the protective layer of the structure + the width of the working face of the structure + the thickness of the support of the structure) + 2 × the excavation slope ratio × the road excavation depth.

[0032] Based on parameters such as the outer contour dimensions, burial depth, and support type of the underground structure, the average excavation length L, depth H, and width W of each road section are calculated.

[0033] The excavation length L of the road section is determined based on the actual laying length of underground structures such as pipelines, culverts, and utility tunnels. It is calculated using the underground structure station numbers and coordinates, and the calculation formula is as follows: L=L0 The excavation depth H of the road section is determined by the burial depth H of the underground structure. q Add basic processing depth H z Ensure the excavation depth meets construction requirements. The calculation formula is as follows: H = (H q +H z ) / 2+T jc +T dc +T ht Where T jc Based on thickness (m), T dc T represents the thickness of the cushion layer (m). ht Thickness of the foundation replacement layer (m) The calculation of the excavation width requires reserving an appropriate width of construction space on both sides of the underground structure. The width of the underground structure is then added to the reserved width on both sides. The calculation formula is as follows: W=D0+2×(B1+B2+B3)+2×m×H Where D0 is the outer contour dimension of the structure (m), B1 is the thickness of the protective layer of the structure (m), B2 is the width of the construction working surface of the structure (m), and B3 is the thickness of the support of the structure (m).

[0034] Furthermore, determining the road repair scope of the road to be repaired based on the basic data and excavation characteristic parameters of the road to be repaired, combined with the differences in the connection between the road to be repaired and the existing road, also includes: The road repair range of the road to be repaired is calculated based on the road surface type in the road status parameters and the determined road excavation characteristic parameters. Based on the differences in the road surface types, the road repair range is calculated separately for the two common road surface types: asphalt pavement and cement concrete pavement.

[0035] In this embodiment, based on the road grade and pavement type in the road status parameters, the component parameters in the standard component selection table are called, and the earthwork and pavement structure standard components of different road sections are automatically matched in sequence to obtain the road excavation and pavement repair design schemes for different road sections, thereby calculating the earthwork volume and pavement repair volume of each road section.

[0036] Furthermore, the calculation of road repair ranges based on the differences in road surface types, specifically for the two common road surface types of asphalt pavement and cement concrete pavement, also includes: When the road surface type is asphalt pavement, based on the structural overlap between the road surface to be repaired and the existing road surface, the overlap repair range is defined by extending a preset distance outward from the road excavation boundary as a reference, and the overlap width is determined according to the road construction process requirements. The road section repair length is determined based on the road repair overlap width and road section excavation length of the asphalt pavement; the road section repair depth is determined based on the road section excavation depth of the asphalt pavement; and the road section repair width is determined based on the road repair overlap width and road section excavation width of the asphalt pavement. When the road surface type is cement concrete pavement, the repair scope is based on the complete slab involved in the excavation area. If the excavation area spans multiple slabs, the entire affected slab will be included in the repair scope. The road section repair length is determined based on the road repair overlap width and road section excavation length of the cement concrete pavement; the road section repair width is determined based on the pavement slab width and road section excavation width of the cement concrete pavement; and the road section repair depth is determined based on the road section excavation depth of the cement concrete pavement.

[0037] In this embodiment, the road repair range is calculated based on the road surface type and the determined road excavation range in the road status parameters. Considering the differences in road surface types, the road repair range is calculated separately for two common road surface types: asphalt pavement and cement concrete pavement.

[0038] If the road surface is asphalt, the structural overlap between the repaired road surface and the existing road surface needs to be considered. The overlap repair range is defined by extending a certain distance outward from the road excavation boundary. The overlap width is determined according to the road construction process requirements.

[0039] Road section repair length L r The calculation formula is as follows: L r =L+2×E Where E is the overlap width of road repair (m), which is 0.2-0.5m for asphalt pavement and 0m for cement pavement.

[0040] Road section repair width W r The calculation formula is as follows: W r =W+2×E Where E is the overlap width of road repair (m), which is 0.2-0.5m for asphalt pavement and 0m for cement pavement.

[0041] Road section repair depth H r The calculation formula is as follows: Hr=H If the pavement type is cement concrete, the characteristics of its slabs need to be considered, and the repair scope should be based on the complete slabs involved in the excavation area. If the excavation area spans multiple slabs, the entire affected slab should be included in the repair scope to ensure the integrity of the repair work.

[0042] Road repair length L r The calculation formula is as follows: L r =L+2×E Where E is the overlap width of road repair (m), which is 0.2-0.5m for asphalt pavement and 0m for cement pavement.

[0043] Road repair width W r The calculation formula is as follows: i) When the width of the road excavation reaches 1 / 2 of the original road width, the surface layer should be fully repaired; W r =W, when W≤1 / 3B h ; ii) When the width of the road excavation in the forward direction is greater than 1 / 3 of the slab width and less than 1 / 2 of the original road width, the entire road surface slab shall be repaired; W r =B h When 1 / 2B ≥ W > 1 / 3B h ; iii) When the width of the road excavation in the forward direction is less than 1 / 3 of the slab width, it shall be treated as reinforcement.

[0044] W r =B, when W>1 / 2B; B represents the current road width; The formula for calculating road repair depth Hr is as follows: H r =H.

[0045] Furthermore, the step of automatically matching road excavation and pavement repair design schemes for different road sections by calling component parameters from the standard component selection table based on the basic data, excavation characteristic parameters, and road repair range of the road to be repaired, and calculating the design quantities of road excavation and pavement repair and traffic diversion design, also includes: Based on the road grade and pavement type in the road status parameters, the component parameters in the standard component selection table are called, and the earthwork and pavement structure standard components of different road sections are automatically matched in sequence to calculate the earthwork volume and pavement repair volume of each road section. The automatic matching of standard components for pavement structure of different road sections in sequence also includes: according to the road grade and pavement type in the current road status parameters, calling the same earthwork and pavement structure components from the standard component selection table, and obtaining the earthwork and pavement structure design parameters. The earthwork volume includes the excavation volume during the excavation of the underground structure and the backfill volume after the underground structure is completed. The calculation of road repair work volume includes asphalt road repair work volume and cement concrete road repair work volume; By using traffic flow prediction models and combining them with traffic organization plans during road excavation and repair, the setting of traffic diversion facilities is determined and the design engineering volume of traffic diversion is calculated. The setting of the traffic diversion facilities also includes: selecting traffic diversion facility components that match the traffic organization plan from the standard component selection table according to the traffic organization plan.

[0046] The traffic diversion design includes construction barriers, temporary traffic signs, temporary traffic markings, temporary traffic lights, traffic control personnel, nighttime warning facilities, safety protection facilities, and temporary roads.

[0047] Furthermore, the earthwork volume includes the excavation volume during the underground structure excavation, the backfill volume after the underground structure construction is completed, and also includes: The excavation volume of the road section is calculated based on the road excavation width, road excavation depth, and road section slope ratio. The embankment volume of the road section is calculated based on the volume occupied by the underground structure, the amount of base course engineering, the amount of subbase engineering, the amount of foundation replacement engineering, and the amount of pavement structure engineering. The calculation of the asphalt pavement repair work also includes the work quantities of surface layer, tack coat, slurry seal, prime coat, stress-absorbing layer, inorganic binder base or plain concrete base, and subbase.
