Description

Technical Field

[0001] This invention belongs to the field of water supply and drainage, and relates to image processing technology. Specifically, it is a real-time settlement monitoring and early warning system and method for water supply and drainage engineering. Background Technology

[0002] Existing real-time settlement monitoring and early warning systems for water supply and drainage engineering have the following specific shortcomings when providing settlement warnings for construction areas:

[0003] 1. Existing real-time settlement monitoring and early warning systems for water supply and drainage projects cannot perform core material position deviation analysis on surface sub-regions, nor can they conduct preliminary settlement screening on surface sub-regions based on the obtained surface settlement monitoring index values. As a result, they cannot identify changes in overburden thickness or abnormal surrounding rock stability through core position deviation, leading to a lack of accuracy in the real-time settlement monitoring process.

[0004] 2. Existing real-time settlement monitoring and early warning systems for water supply and drainage projects cannot perform settlement analysis on each surface sub-region based on surface settlement monitoring data to divide the surface sub-region into first-type settlement sub-regions and second-type settlement sub-regions, and cannot monitor pipeline deformation in the second-type settlement sub-regions, resulting in a lack of specificity in the settlement monitoring process.

[0005] Therefore, we propose a real-time settlement monitoring and early warning system and method for water supply and drainage engineering. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a real-time settlement monitoring and early warning system and method for water supply and drainage engineering, thereby improving the accuracy and relevance of the real-time settlement monitoring and early warning system for water supply and drainage engineering.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a real-time settlement monitoring and early warning system for water supply and drainage engineering, comprising:

[0008] Surface monitoring module: Monitors surface settlement in the construction area of ​​water supply and drainage projects, and obtains surface settlement monitoring data based on the monitoring results;

[0009] Pipeline monitoring module: Based on the surface subsidence monitoring data, the subsidence analysis is performed on each surface sub-region. Based on the analysis results, the surface sub-region is divided into a first type of subsidence sub-region and a second type of subsidence sub-region. Pipeline deformation monitoring is performed on the second type of subsidence sub-region, and pipeline deformation monitoring data is obtained based on the monitoring results.

[0010] Monitoring and early warning module: Provide regional subsidence early warning for each subsidence sub-region based on pipeline deformation monitoring data.

[0011] Furthermore, surface subsidence monitoring data were acquired, as follows:

[0012] The surface area where water supply and drainage engineering needs to be carried out is obtained to obtain the surface settlement monitoring area. The obtained surface settlement area is divided into several surface settlement sub-regions, and a sample surface sub-region is selected from the several surface sediment sub-regions.

[0013] Surface subsidence monitoring was conducted on the sample sub-regions, and the surface subsidence monitoring index values ​​corresponding to the sample sub-regions were obtained based on the monitoring results.

[0014] The process of obtaining the surface subsidence monitoring index values ​​corresponding to the sample surface sub-regions was repeated to obtain the surface subsidence monitoring index values ​​corresponding to each surface sediment sub-region, thus obtaining the surface subsidence monitoring data.

[0015] Furthermore, the values ​​of surface subsidence monitoring indicators were obtained, as follows:

[0016] Within the sample surface sub-region, several surface monitoring feature lines are set up, and one sample surface feature monitoring line is selected from among the set surface feature lines.

[0017] Several sets of sediment monitoring points were selected along the surface feature monitoring line of the sample. The settling monitoring points included the first settling monitoring point and the second settling monitoring point.

[0018] Randomly select a set of sediment monitoring points to perform core material analysis, and obtain the core material deviation based on the analysis results;

[0019] The deviation of core material corresponding to each set of sediment monitoring points was obtained, and the average of the obtained deviations of multiple core materials was calculated to obtain the surface subsidence value corresponding to the surface feature monitoring line of the sample.

[0020] The surface subsidence values ​​corresponding to each surface feature monitoring line are obtained separately, and the values ​​of the multiple obtained surface subsidence values ​​are compared. The surface subsidence value with the largest value is marked as the surface subsidence monitoring index value corresponding to the sample surface sub-region.

[0021] Furthermore, core material analysis was performed on the sedimentary monitoring assemblages, as detailed below:

[0022] Before carrying out water supply and drainage construction in the surface subsidence monitoring area, core drilling was performed on the first subsidence monitoring point using core drilling equipment to obtain the first subsidence characteristic core. The material sedimentary layers corresponding to the first subsidence characteristic core were obtained and marked as T1 material layer to Ta material layer.

[0023] In the first sedimentation characteristic core, the initial appearance depths of the T1 material layer to the Ta material layer in the first sedimentation characteristic core were obtained, and the values ​​of the T1 material unconstructed depth to the Ta material unconstructed depth were obtained.

[0024] After water supply and drainage construction was carried out in the surface settlement monitoring area, core samples were obtained from the second settlement monitoring point using core drilling equipment to obtain the second settlement characteristic core.

[0025] Furthermore, the deviations in the core material were obtained, as follows:

[0026] In the second sedimentation characteristic core, the depths of T1 material stratification to Ta material stratification in the second sedimentation characteristic core were obtained respectively, and the depth values ​​of T1 material stratification to Ta material stratification were obtained.

[0027] The deviation of the core material corresponding to the first settlement monitoring point and the second settlement monitoring point is obtained by calculating the difference between the unconstructed depth value of T1 material and the unconstructed depth value of Ta material, and the difference between the constructed depth value of T1 material and the constructed depth value of Ta material.

[0028] The settlement values ​​of the rock strata were calculated.

[0029] Furthermore, pipeline deformation monitoring data were acquired, as follows:

[0030] Obtain surface subsidence monitoring data, and obtain multiple surface subsidence monitoring index values ​​based on the surface subsidence monitoring data;

[0031] Obtain the reference range of surface subsidence monitoring values. If the surface subsidence monitoring index value is within the reference range of surface subsidence monitoring values, the corresponding surface sub-region is divided into the first type of subsidence sub-region. If the surface subsidence monitoring index value is not within the reference range of surface subsidence monitoring values, the corresponding surface sub-region is divided into the second type of subsidence sub-region, thus obtaining the initial screening data of subsidence areas.

[0032] If the sample surface sub-region is a first-type settlement sub-region, pipeline deformation monitoring is carried out on the sample surface sub-region, and the deformation area ratio of the pipeline area corresponding to the sample surface sub-region is obtained based on the monitoring results.

[0033] Repeat the process of obtaining the deformation area ratio of the pipeline area corresponding to the sample surface sub-region, and obtain the deformation area ratio of the pipeline area corresponding to each first type of settlement sub-region respectively.

[0034] The pipeline deformation area ratio corresponding to each first-type settlement sub-region and the initial screening data of the settlement region are defined as pipeline deformation monitoring data.

[0035] Furthermore, the deformation area ratio of the pipeline region is obtained, as follows:

[0036] The underground drainage pipeline corresponding to the sample surface sub-region is obtained, and several image acquisition devices are installed inside the sample drainage pipeline.

[0037] Multiple real-time cross-sectional images of the sample drainage pipeline at the equipment installation location are obtained by using an image acquisition device.

[0038] The image acquisition device acquires initial images of the interior of the sample drainage pipeline corresponding to each device installation location, resulting in multiple initial cross-sectional images;

[0039] Overlay the real-time cross-sectional image with the corresponding initial cross-sectional image, mark the image areas where the real-time cross-sectional image and the corresponding initial cross-sectional image can overlap as the cross-sectional image overlap area, obtain the area value of the cross-sectional image overlap area, obtain the cross-sectional overlap area by obtaining the area of ​​the initial cross-sectional image;

[0040] The ratio of cross-sectional deformation area is obtained by calculating the overlapping area of ​​the cross sections and the initial cross-sectional area.

[0041] The cross-sectional deformation area ratio between each real-time cross-sectional image and the corresponding initial cross-sectional image is obtained. The values ​​of the obtained cross-sectional deformation area ratios are compared, and the cross-sectional deformation area ratio with the largest value is marked as the pipeline area deformation area ratio.

[0042] Furthermore, regional subsidence early warning is implemented for each subsidence subsidence sub-region, as detailed below:

[0043] Acquire pipeline deformation monitoring data, obtain preliminary screening data of settlement area based on pipeline deformation monitoring data, and obtain the first type of settlement sub-region and the second type of settlement sub-region based on the preliminary screening data of settlement area.

[0044] If the surface subsidence sub-region is a first-type subsidence sub-region, then the pipeline area deformation ratio analysis is performed on the surface subsidence sub-region, and a pipeline subsidence early warning is issued based on the analysis results;

[0045] If the sub-region of surface subsidence is a sub-region of type II subsidence, it is determined that subsidence has occurred in the corresponding sub-region of surface subsidence, and a subsidence warning is issued immediately.

[0046] Furthermore, an analysis of the pipeline area deformation ratio was conducted for the surface subsidence sub-region, as detailed below:

[0047] Obtain the ratio of pipeline area deformation to the sub-region of surface subsidence, and obtain the reference range of pipeline area deformation.

[0048] If the deformation area ratio of the pipeline area is within the baseline range of the deformation area of ​​the pipeline area, it is determined that no subsidence has occurred in the corresponding subsidence sub-area, and there is no need to issue a subsidence warning.

[0049] If the deformation area ratio of the pipeline area is not within the baseline range of the deformation area of ​​the pipeline area, it is determined that the corresponding subsidence subsidence subsidence subsidence subsidence has occurred, and a subsidence warning is issued immediately.

[0050] A method for real-time monitoring and early warning of settlement in water supply and drainage engineering includes the following specific steps:

[0051] Step S1: Conduct surface settlement monitoring in the construction area of ​​the water supply and drainage project, and obtain surface settlement monitoring data based on the monitoring results;

[0052] Step S2: Perform subsidence analysis on each sub-region of the surface based on the surface subsidence monitoring data. Based on the analysis results, divide the sub-region of the surface into a first type of subsidence sub-region and a second type of subsidence sub-region. Perform pipeline deformation monitoring on the second type of subsidence sub-region and obtain pipeline deformation monitoring data based on the monitoring results.

[0053] Step S3: Based on pipeline deformation monitoring data, conduct regional subsidence early warning for each subsidence sub-region.

[0054] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0055] 1. This invention analyzes the positional deviation of core materials in a sub-region of the Earth's surface and uses the obtained surface subsidence monitoring index values ​​to conduct preliminary screening of the sub-region's subsidence. By identifying changes in the thickness of the overburden layer or abnormal stability of the surrounding rock through core positional deviation, the accuracy of the real-time subsidence monitoring process is ensured.

[0056] 2. This invention divides each sub-region of the surface into a first type of subsidence sub-region and a second type of subsidence sub-region by performing subsidence analysis on each sub-region based on surface subsidence monitoring data, and performs pipeline deformation monitoring on the second type of subsidence sub-region, which can effectively improve the targeting of the subsidence monitoring process.

[0061] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example

[0062] Please see Figure 1 The image acquisition device in this invention has a built-in image processor. This invention provides a technical solution: a real-time settlement monitoring and early warning system for water supply and drainage engineering. The monitoring and early warning system includes a surface monitoring module, a pipeline monitoring module, a monitoring and early warning module, and a server. The surface monitoring module, pipeline monitoring module, and monitoring and early warning module are respectively connected to the server, and the server controls the surface monitoring module, pipeline monitoring module, and monitoring and early warning module respectively.

[0063] The surface monitoring module monitors surface settlement in the construction area of ​​water supply and drainage projects and obtains surface settlement monitoring data based on the monitoring results.

[0064] Specifically as follows:

[0065] The surface area where water supply and drainage engineering needs to be carried out is obtained to obtain the surface settlement monitoring area. The obtained surface settlement area is divided into several surface settlement sub-regions, and a sample surface sub-region is selected from the several surface sediment sub-regions.

[0066] Surface subsidence monitoring was conducted on the sample sub-regions, and the surface subsidence monitoring index values ​​corresponding to the sample sub-regions were obtained based on the monitoring results.

[0067] Specifically as follows:

[0068] Within the sample surface sub-region, several surface monitoring feature lines are set up, and one sample surface feature monitoring line is selected from among the set surface feature lines.

[0069] Several sets of sediment monitoring points were selected along the surface feature monitoring line of the sample. The settling monitoring points included the first settling monitoring point and the second settling monitoring point.

[0070] It should be noted here that:

[0071] Please see Figure 3In this application, the first settlement monitoring point and the second settlement monitoring point are both located in the surface area corresponding to the surface feature monitoring line of the sample, and the core drilling locations corresponding to the first settlement monitoring point and the second settlement monitoring point are adjacent to each other.

[0072] Before carrying out water supply and drainage construction in the surface subsidence monitoring area, core drilling was performed on the first subsidence monitoring point using core drilling equipment to obtain the first subsidence characteristic core. The material sedimentary layers corresponding to the first subsidence characteristic core were obtained and marked as T1 material layer to Ta material layer.

[0073] It should be noted here that:

[0074] In this application, T is the symbol corresponding to the material deposition layer, and a is the quantity value corresponding to the material deposition layer, and a is an integer greater than 0;

[0075] In this application, the T1 material layer can be a topsoil layer, the T2 material layer can be a soil sediment layer, and the T3 material layer can be a rock sediment layer.

[0076] In the first sedimentation characteristic core, the initial appearance depths of the T1 material layer to the Ta material layer in the first sedimentation characteristic core were obtained, and the values ​​of the T1 material unconstructed depth to the Ta material unconstructed depth were obtained.

[0077] After water supply and drainage construction was carried out in the surface settlement monitoring area, core drilling was performed on the second settlement monitoring point using core drilling equipment to obtain the second settlement characteristic core.

[0078] In the second sedimentation characteristic core, the depths of T1 material stratification to Ta material stratification in the second sedimentation characteristic core were obtained respectively, and the depth values ​​of T1 material stratification to Ta material stratification were obtained.

[0079] The deviation of the core material corresponding to the first settlement monitoring point and the second settlement monitoring point is obtained by calculating the difference between the unconstructed depth value of T1 material and the unconstructed depth value of Ta material, and the difference between the constructed depth value of T1 material and the constructed depth value of Ta material.

[0080] The specific formula for calculating rock strata settlement is as follows:

[0081] ;

[0082] Where Ycj is the core material deviation corresponding to the first settlement monitoring point and the second settlement monitoring point, Jjqi is the value of the unconstructed depth of Ti material, Jjhi is the value of the constructed depth of Ti material, and a is the quantity value corresponding to the material deposition layer.

[0083] It should be noted here that:

[0084] In this application, the unconstructed depth of Ti material can be from the unconstructed depth of T1 material to the unconstructed depth of Ta material, and the constructed depth of Ti material can be from the constructed depth of T1 material to the constructed depth of Ta material.

[0085] The process of obtaining the core material deviations corresponding to the first and second settlement monitoring points was repeated. The core material deviations corresponding to each pair of sedimentary monitoring points were obtained separately, and the average of the obtained core material deviations was calculated to obtain the surface settlement value corresponding to the surface feature monitoring line of the sample.

[0086] Repeat the process of obtaining the surface subsidence values ​​corresponding to the surface feature monitoring lines of the sample, obtain the surface subsidence values ​​corresponding to each surface feature monitoring line, compare the values ​​of the multiple obtained surface subsidence values, and mark the surface subsidence value with the largest value as the surface subsidence monitoring index value corresponding to the sample surface sub-region.

[0087] Repeat the process of obtaining the surface subsidence monitoring index values ​​corresponding to the sample surface sub-regions, and obtain the surface subsidence monitoring index values ​​corresponding to each surface sediment sub-region to obtain surface subsidence monitoring data.

[0088] The surface monitoring module acquires surface subsidence monitoring data and transmits it to the pipeline monitoring module;

[0089] The pipeline monitoring module performs settlement analysis on each surface sub-region based on the surface settlement monitoring data. Based on the analysis results, the surface sub-region is divided into a first type of settlement sub-region and a second type of settlement sub-region. Pipeline deformation monitoring is performed on the second type of settlement sub-region, and pipeline deformation monitoring data is obtained based on the monitoring results.

[0090] Specifically as follows:

[0091] Obtain surface subsidence monitoring data, and obtain multiple surface subsidence monitoring index values ​​based on the surface subsidence monitoring data;

[0092] Obtain the reference range of surface subsidence monitoring values. If the surface subsidence monitoring index value is within the reference range of surface subsidence monitoring values, the corresponding surface sub-region is divided into the first type of subsidence sub-region. If the surface subsidence monitoring index value is not within the reference range of surface subsidence monitoring values, the corresponding surface sub-region is divided into the second type of subsidence sub-region, thus obtaining the initial screening data of subsidence areas.

[0093] It should be noted here that:

[0094] In this application, the second type of subsidence sub-region involved here includes the case where the surface subsidence monitoring index value is at the boundary of the surface subsidence monitoring numerical benchmark interval;

[0095] The baseline interval for surface subsidence monitoring values ​​was obtained, as detailed below:

[0096] In this application, the lower limit of the reference range for surface subsidence monitoring values ​​is 0, meaning that no ground subsidence has occurred.

[0097] Several historical monitoring sub-regions with known surface subsidence were obtained. The surface subsidence monitoring index values ​​corresponding to each historical monitoring sub-region were acquired. The values ​​of the acquired surface subsidence monitoring index values ​​were compared, and the surface subsidence monitoring index value with the smallest value was marked as the upper limit of the benchmark interval for surface subsidence monitoring values.

[0098] It should be noted here that:

[0099] In this application, the first type of subsidence sub-region referred to herein is a surface sub-region in which no subsidence has occurred, and the second type of subsidence sub-region referred to herein is a surface sub-region in which subsidence has occurred.

[0100] If the sample surface sub-region is a first-type settlement sub-region, pipeline deformation monitoring is carried out on the sample surface sub-region, and the deformation area ratio of the pipeline area corresponding to the sample surface sub-region is obtained based on the monitoring results.

[0101] Specifically as follows:

[0102] The underground drainage pipeline corresponding to the sample surface sub-region is obtained, and several image acquisition devices are installed inside the sample drainage pipeline.

[0103] Multiple real-time cross-sectional images of the sample drainage pipeline at the equipment installation location are obtained by using an image acquisition device.

[0104] The image acquisition device acquires initial images of the interior of the sample drainage pipeline corresponding to each device installation location, resulting in multiple initial cross-sectional images;

[0105] Overlay the real-time cross-sectional image with the corresponding initial cross-sectional image, mark the image areas where the real-time cross-sectional image and the corresponding initial cross-sectional image can overlap as the cross-sectional image overlap area, obtain the area value of the cross-sectional image overlap area, obtain the cross-sectional overlap area by obtaining the area of ​​the initial cross-sectional image;

[0106] The ratio of the cross-sectional deformation area is calculated by combining the overlapping area of ​​the cross-section and the initial cross-sectional area, using the following formula:

[0107] ;

[0108] Where Xbb is the cross-sectional deformation area ratio, Scs is the initial cross-sectional area, and Ssh is the overlapping area of ​​the cross-sections;

[0109] The cross-sectional deformation area ratio between each real-time cross-sectional image and the corresponding initial cross-sectional image is obtained. The values ​​of the obtained cross-sectional deformation area ratios are compared, and the cross-sectional deformation area ratio with the largest value is marked as the pipeline area deformation area ratio.

[0110] Repeat the process of obtaining the deformation area ratio of the pipeline area corresponding to the sample surface sub-region, and obtain the deformation area ratio of the pipeline area corresponding to each first type of settlement sub-region respectively.

[0111] The pipeline deformation area ratio corresponding to each first-type settlement sub-region and the initial screening data of the settlement region are defined as pipeline deformation monitoring data.

[0112] The monitoring and early warning module provides regional subsidence early warning for each subsidence sub-region based on pipeline deformation monitoring data.

[0113] Specifically as follows:

[0114] Acquire pipeline deformation monitoring data, obtain preliminary screening data of settlement area based on pipeline deformation monitoring data, and obtain the first type of settlement sub-region and the second type of settlement sub-region based on the preliminary screening data of settlement area.

[0115] If the surface subsidence sub-region is a first-type subsidence sub-region, then the pipeline area deformation ratio analysis is performed on the surface subsidence sub-region, and a pipeline subsidence early warning is issued based on the analysis results;

[0116] If the sub-region of surface subsidence is a sub-region of type II subsidence, it is determined that the corresponding sub-region of surface subsidence has subsided, and a subsidence warning is issued immediately.

[0117] Specifically as follows:

[0118] Obtain the ratio of pipeline area deformation to the sub-region of surface subsidence, and obtain the reference range of pipeline area deformation.

[0119] If the deformation area ratio of the pipeline area is within the baseline range of the deformation area of ​​the pipeline area, it is determined that no subsidence has occurred in the corresponding subsidence sub-area, and there is no need to issue a subsidence warning.

[0120] If the deformation area ratio of the pipeline area is not within the baseline range of the deformation area of ​​the pipeline area, it is determined that the corresponding subsidence sub-area has subsided, and a subsidence warning is issued immediately.

[0121] It should be noted here that:

[0122] In this application, the lower limit of the reference range for the deformation area of ​​the pipeline region involved here is 0, that is, no deformation occurs in the pipeline cross-section;

[0123] Several historical monitoring sub-regions with known surface subsidence were obtained. The deformation area ratio of the pipeline area corresponding to each historical monitoring sub-region was obtained. The deformation area ratios of the pipeline areas were compared numerically, and the pipeline area deformation area ratio with the smallest value was marked as the upper limit of the benchmark interval of pipeline area deformation area.

[0124] In this application, the sub-region of surface subsidence involved here has shown that the subsidence includes the pipeline area deformation area ratio being at the boundary of the pipeline area deformation area benchmark interval.

[0125] In this application, if a corresponding calculation formula appears, the above calculation formula is a dimensionless calculation. The weighting coefficient, proportional coefficient and other coefficients in the formula are set to quantify each parameter to obtain a result value. The size of the weighting coefficient and proportional coefficient is only required to not affect the proportional relationship between the parameter and the result value.

[0126] Example 2

[0127] Please see Figure 2 Based on another concept of the same invention, a real-time settlement monitoring and early warning method for water supply and drainage engineering is proposed, comprising the following steps:

[0128] Step S1: Conduct surface settlement monitoring in the construction area of ​​the water supply and drainage project, and obtain surface settlement monitoring data based on the monitoring results;

[0129] Step S1 further includes the following specific steps:

[0130] The surface area where water supply and drainage engineering needs to be carried out is obtained to obtain the surface settlement monitoring area. The obtained surface settlement area is divided into several surface settlement sub-regions, and a sample surface sub-region is selected from the several surface sediment sub-regions.

[0131] Surface subsidence monitoring was conducted on the sample sub-regions, and the surface subsidence monitoring index values ​​corresponding to the sample sub-regions were obtained based on the monitoring results.

[0132] Specifically as follows:

[0133] Within the sample surface sub-region, several surface monitoring feature lines are set up, and one sample surface feature monitoring line is selected from among the set surface feature lines.

[0134] Several sets of sediment monitoring points were selected along the surface feature monitoring line of the sample. The settling monitoring points included the first settling monitoring point and the second settling monitoring point.

[0135] Randomly select a set of sediment monitoring points to perform core material analysis, and obtain the core material deviation based on the analysis results;

[0136] Specifically as follows:

[0137] Before carrying out water supply and drainage construction in the surface subsidence monitoring area, core drilling was performed on the first subsidence monitoring point using core drilling equipment to obtain the first subsidence characteristic core. The material sedimentary layers corresponding to the first subsidence characteristic core were obtained and marked as T1 material layer to Ta material layer.

[0138] In the first sedimentation characteristic core, the initial appearance depths of the T1 material layer to the Ta material layer in the first sedimentation characteristic core were obtained, and the values ​​of the T1 material unconstructed depth to the Ta material unconstructed depth were obtained.

[0139] After water supply and drainage construction was carried out in the surface settlement monitoring area, core drilling was performed on the second settlement monitoring point using core drilling equipment to obtain the second settlement characteristic core.

[0140] In the second sedimentation characteristic core, the depths of T1 material stratification to Ta material stratification in the second sedimentation characteristic core were obtained respectively, and the depth values ​​of T1 material stratification to Ta material stratification were obtained.

[0141] The deviation of the core material corresponding to the first settlement monitoring point and the second settlement monitoring point is obtained by calculating the difference between the unconstructed depth value of T1 material and the unconstructed depth value of Ta material, and the difference between the constructed depth value of T1 material and the constructed depth value of Ta material.

[0142] The specific formula for calculating rock strata settlement is as follows:

[0143] ;

[0144] Where Ycj is the core material deviation corresponding to the first settlement monitoring point and the second settlement monitoring point, Jjqi is the value of the unconstructed depth of Ti material, Jjhi is the value of the constructed depth of Ti material, and a is the quantity value corresponding to the material deposition layer.

[0145] The process of obtaining the core material deviations corresponding to the first and second settlement monitoring points was repeated. The core material deviations corresponding to each set of sediment monitoring points were obtained separately, and the average of the obtained core material deviations was calculated to obtain the surface settlement value corresponding to the surface feature monitoring line of the sample.

[0146] Repeat the process of obtaining the surface subsidence values ​​corresponding to the surface feature monitoring lines of the sample, obtain the surface subsidence values ​​corresponding to each surface feature monitoring line, compare the values ​​of the multiple obtained surface subsidence values, and mark the surface subsidence value with the largest value as the surface subsidence monitoring index value corresponding to the sample surface sub-region.

[0147] Repeat the process of obtaining the surface subsidence monitoring index values ​​corresponding to the sample surface sub-regions, and obtain the surface subsidence monitoring index values ​​corresponding to each surface sediment sub-region to obtain surface subsidence monitoring data.

[0148] The above step S1 has the following advantages:

[0149] 1. By combining regional grid monitoring with core material stratification analysis, the geological changes in the construction-affected area can be tracked in a refined manner. This method can effectively identify local stratum subsidence characteristics by comparing the sedimentary stratification depth of cores before and after construction. At the same time, by fusion of data from multiple monitoring points, it provides a scientific basis for assessing the scope and degree of construction disturbance.

[0150] 2. By constructing a three-dimensional dynamic mapping system for geological parameters, a multi-dimensional analysis of construction disturbance effects was achieved. Its innovative advantages are reflected in: based on the coupled analysis of gridded monitoring network and core material fingerprint characteristics, not only was a spatiotemporal benchmark for geological structure evolution established, but also the hidden settlement law was revealed through the quantification of layered depth variation coefficient; the use of a homologous comparison mechanism of core sequences before and after construction effectively eliminated regional geological background interference.

[0151] Step S2: Perform subsidence analysis on each sub-region of the surface based on the surface subsidence monitoring data. Based on the analysis results, divide the sub-region of the surface into a first type of subsidence sub-region and a second type of subsidence sub-region. Perform pipeline deformation monitoring on the second type of subsidence sub-region and obtain pipeline deformation monitoring data based on the monitoring results.

[0152] Step S2 further includes the following specific steps:

[0153] Obtain surface subsidence monitoring data, and obtain multiple surface subsidence monitoring index values ​​based on the surface subsidence monitoring data;

[0154] Obtain the reference range of surface subsidence monitoring values. If the surface subsidence monitoring index value is within the reference range of surface subsidence monitoring values, the corresponding surface sub-region is divided into the first type of subsidence sub-region. If the surface subsidence monitoring index value is not within the reference range of surface subsidence monitoring values, the corresponding surface sub-region is divided into the second type of subsidence sub-region, thus obtaining the initial screening data of subsidence areas.

[0155] If the sample surface sub-region is a first-type settlement sub-region, pipeline deformation monitoring is carried out on the sample surface sub-region, and the deformation area ratio of the pipeline area corresponding to the sample surface sub-region is obtained based on the monitoring results.

[0156] Specifically as follows:

[0157] The underground drainage pipeline corresponding to the sample surface sub-region is obtained, and several image acquisition devices are installed inside the sample drainage pipeline.

[0158] Multiple real-time cross-sectional images of the sample drainage pipeline at the equipment installation location are obtained by using an image acquisition device.

[0159] The image acquisition device acquires initial images of the interior of the sample drainage pipeline corresponding to each device installation location, resulting in multiple initial cross-sectional images;

[0160] Overlay the real-time cross-sectional image with the corresponding initial cross-sectional image, mark the image areas where the real-time cross-sectional image and the corresponding initial cross-sectional image can overlap as the cross-sectional image overlap area, obtain the area value of the cross-sectional image overlap area, obtain the cross-sectional overlap area by obtaining the area of ​​the initial cross-sectional image;

[0161] The ratio of the cross-sectional deformation area is calculated by combining the overlapping area of ​​the cross-section and the initial cross-sectional area, using the following formula:

[0162] ;

[0163] Where Xbb is the cross-sectional deformation area ratio, Scs is the initial cross-sectional area, and Ssh is the overlapping area of ​​the cross-sections;

[0164] The cross-sectional deformation area ratio between each real-time cross-sectional image and the corresponding initial cross-sectional image is obtained. The values ​​of the obtained cross-sectional deformation area ratios are compared, and the cross-sectional deformation area ratio with the largest value is marked as the pipeline area deformation area ratio.

[0165] Repeat the process of obtaining the deformation area ratio of the pipeline area corresponding to the sample surface sub-region, and obtain the deformation area ratio of the pipeline area corresponding to each first type of settlement sub-region respectively.

[0166] The pipeline deformation area ratio corresponding to each first-type settlement sub-region and the initial screening data of the settlement region are defined as pipeline deformation monitoring data.

[0167] The following advantages exist in step S2 above:

[0168] 1. By combining surface settlement classification with comparative analysis of pipeline internal images, precise screening of potential risks was achieved. This method utilizes image overlay technology to quantify the degree of pipeline cross-sectional deformation, effectively identifying local structural anomalies. Simultaneously, by prioritizing areas outside the settlement baseline through a regional classification mechanism, it optimizes the efficiency of monitoring resource allocation.

[0169] 2. By constructing a surface-pipeline collaborative monitoring system, multi-dimensional and three-dimensional management of construction impacts has been achieved. Its innovative advantages are reflected in: establishing a dynamic correlation model between surface settlement thresholds and pipeline deformation parameters to achieve quantitative classification of risk levels; employing pipeline endoscopic imaging and image registration technology to overcome the limitations of traditional external detection and accurately capture hidden structural deformations; triggering differentiated monitoring strategies through settlement area classification to ensure high-frequency monitoring of key areas while optimizing overall monitoring resource allocation; establishing a cross-sectional deformation area ratio index system to transform geometric deformation into quantifiable safety thresholds, providing direct evidence for pipeline bearing capacity assessment; and further integrating real-time monitoring data with historical deformation databases to construct a dynamic risk assessment model, achieving a shift from passive response to proactive early warning and providing data-driven intelligent support for pipeline maintenance decisions.

[0170] Step S3: Based on pipeline deformation monitoring data, conduct regional subsidence early warning for each subsidence sub-region;

[0171] Step S3 further includes the following specific steps:

[0172] Acquire pipeline deformation monitoring data, obtain preliminary screening data of settlement area based on pipeline deformation monitoring data, and obtain the first type of settlement sub-region and the second type of settlement sub-region based on the preliminary screening data of settlement area.

[0173] If the surface subsidence sub-region is a first-type subsidence sub-region, then the pipeline area deformation ratio analysis is performed on the surface subsidence sub-region, and a pipeline subsidence early warning is issued based on the analysis results;

[0174] If the sub-region of surface subsidence is a sub-region of type II subsidence, it is determined that the corresponding sub-region of surface subsidence has subsided, and a subsidence warning is issued immediately.

[0175] Specifically as follows:

[0176] Obtain the ratio of pipeline area deformation to the sub-region of surface subsidence, and obtain the reference range of pipeline area deformation.

[0177] If the deformation area ratio of the pipeline area is within the baseline range of the deformation area of ​​the pipeline area, it is determined that no subsidence has occurred in the corresponding subsidence sub-area, and there is no need to issue a subsidence warning.

[0178] If the deformation area ratio of the pipeline area is not within the baseline range of the deformation area of ​​the pipeline area, it is determined that the corresponding subsidence subsidence subsidence subsidence subsidence has occurred, and a subsidence warning is issued immediately.
