[0085] Specifically, the embodiment of the present invention uses drones for scanning to quickly obtain high-precision terrain data and construct a detailed three-dimensional model, which provides an accurate basis for subsequent analysis. By identifying the terrain of the three-dimensional model, the geographical characteristics of the area to be installed are fully understood, providing an important reference for the design of the drainage system. By analyzing the low-lying terrain in the model, the installation location of the drainage device is selected in a targeted manner, providing an accurate basis for the installation of the drainage device. By detecting the slope value of the adjacent area of ​​the low-lying terrain, the misjudgment and omission of the installation location is reduced, ensuring the effective coverage of the drainage device.

[0093] Specifically, the embodiment of the present invention calculates the elevation values ​​of points in the model through an elevation analysis algorithm, draws an elevation distribution map, accurately identifies low-lying terrain, and provides accurate information for the installation of drainage devices.

[0094] Specifically, the step of calculating the installation score based on actual soil data includes:

[0095] collecting actual soil density and actual water content of a number of the initial installation sub-areas;

[0096] Calculating a soil score based on the actual soil density and a preset soil density range;

[0097] Calculating a moisture score based on the actual moisture content and a preset moisture content range;

[0098] The installation score is calculated according to the soil score, the moisture score and a preset weight.

[0099] Specifically, the actual soil density can be collected by using a professional soil density tester, such as a nuclear density meter, a penetrometer, etc. to measure the soil in the selected area on the spot and record the soil density data of each sample point;

[0100] The actual moisture content can be collected by using a soil moisture meter, such as a time domain reflectometer TDR, a frequency domain reflectometer FDR, etc. to measure the actual moisture content of the soil.

[0101] Specifically, the preset soil density range of the embodiment of the present invention is 1.5-2.0g / cm3, and the preset moisture content is 15%-25%. The preset soil density and the preset moisture content are determined based on the maximum and minimum values ​​of the soil density and the maximum and minimum values ​​of the moisture content at the historical drainage device installation location.

[0102] Specifically, the soil score in the embodiment of the present invention is that when the actual soil density is within the preset soil density range, the soil score is 1;

[0103] When the actual soil density is greater than the maximum value of the preset soil density range, the soil score is 0;

[0104] When the actual soil density is less than the preset minimum value of the soil density range, the soil score is the difference between the preset minimum value of the soil density range and the actual soil density divided by the preset minimum value of the soil density range.

[0105] Specifically, the moisture score in the embodiment of the present invention is that when the actual moisture content is within the preset moisture content range, the moisture score is 1;

[0106] When the actual water content is greater than the maximum value of the preset water content range, the water content score is 0;

[0107] When the actual water content is less than the minimum value of the preset water content range, the water content score is the difference between the minimum value of the preset water content range and the actual water content divided by the minimum value of the preset water content range.

[0114] Specifically, the preset score in the embodiment of the present invention is 0.5.

[0115] See also Figure 3 As shown, it is an embodiment of the plan view of the initial installation area of ​​the construction method of the environmental adaptive drainage device based on intelligent control provided by the embodiment of the present invention.

[0116] Specifically, the embodiment of the present invention draws a plan view to intuitively display the installation score on the initial installation sub-area, which is convenient for quickly understanding the soil conditions of each area, and screens out the initial installation sub-areas that meet the conditions through preset scores, thereby reducing unnecessary construction volume and reducing construction costs. By calculating and comparing the installation scores of adjacent areas, the area with the largest score sum is selected as the actual installation area, ensuring that the drainage device is installed under the optimal soil conditions, thereby improving the use effect and reliability of the drainage device.

[0122] Step S350: determining an initial installation depth and an initial installation cross-sectional area according to the maximum surface water level.

[0123] Specifically, the embodiments of the present invention provide a basis for subsequent analysis by acquiring historical rainfall and surface water level data, thereby ensuring the accuracy of the basis for installation decisions, and provide important references for prediction and design by matching the correlation between rainfall and surface water level analysis. By constructing a time series model and a rainfall prediction model, rainfall conditions are predicted to provide information for the design of the drainage system, and by predicting the correlation between the maximum rainfall and the surface water level, the maximum water level is predicted to provide an accurate basis for the initial installation depth and cross-sectional area setting of the drainage device.

[0124] Specifically, the embodiment of the present invention can determine the correlation between rainfall and surface water level by using statistical methods such as Pearson correlation coefficient to analyze the matched data and calculate the correlation coefficient to determine the correlation between rainfall and surface water level through the correlation coefficient.

[0128] Determining the safe water depth according to the difference between the maximum surface water level and the preset safe water level;

[0129] Calculating a target drainage flow rate according to the safe water depth and a preset soil permeability coefficient;

[0130] The initial installation depth is calculated according to the maximum surface water level, and the initial installation cross-sectional area is calculated based on the target drainage flow rate.

[0131] Specifically, the preset safety water level in the embodiment of the present invention is the average of several historical surface water levels;

[0132] The preset soil permeability coefficient is a soil permeability coefficient measured by a permeability experiment on a plurality of soil samples collected from the area to be installed.

[0133] Specifically, the target drainage flow rate in the embodiment of the present invention = safe water depth × soil permeability coefficient × area of ​​the area to be installed;

[0134] The initial installation depth = maximum surface water level + safety margin, wherein the safety margin is calculated based on the average of the difference between the installation depth of several historical drainage devices and the maximum surface water level;

[0135] The initial installation cross-sectional area = drainage volume / (target drainage flow×target time), wherein the drainage volume is obtained by the maximum rainfall and the area of ​​the area to be installed, and the target time is the average of historical drainage times.

[0136] Specifically, an example of calculating the initial installation cross-sectional area according to an embodiment of the present invention is that the predicted maximum rainfall is 600 mm, the drainage area is 10,000 square meters, the drainage volume is 600 mm × 10,000 square meters = 6,000 cubic meters, the target drainage flow rate is 500 cubic meters / hour, and the target drainage time is within 6 hours, then the initial installation cross-sectional area = 6,000 cubic meters / (500 cubic meters / hour × 6 hours) = 20 square meters.

[0143] Identify a number of actual installation areas in the area to be installed, install the drainage device in the actual installation area according to the initial installation data, and obtain an initial model;

[0144] According to the initial model, the operation status of the drainage device under different rainfall conditions is simulated by simulation software, and the real-time water level change and real-time drainage efficiency of each actual installation area are recorded.

[0145] Specifically, the step of adjusting the actual installation area and the initial installation data based on the stability test result includes:

[0146] When the real-time water level change is less than or equal to the preset water level change and the real-time drainage efficiency is less than or equal to the preset drainage efficiency, the initial installation data is added;

[0147] When the real-time water level change is greater than the preset water level change or the real-time drainage efficiency is greater than the preset drainage efficiency, the actual installation area is reduced or the initial installation data is reduced.

[0148] Specifically, the preset water level change in the embodiment of the present invention is 1 / 10 of the maximum water level drop per hour;

[0149] The preset drainage efficiency is the target drainage flow rate.

[0158] Or, based on the water level difference and the efficiency difference, reduction data of the initial installation data is calculated, and the initial installation depth and the initial installation cross-sectional area are reduced according to the reduction data.

[0159] Specifically, an example of reducing the actual installation area or reducing the initial installation data in the embodiment of the present invention is:

[0160] Calculate the water level difference:

[0161] The real-time monitored water level change is 0.5 meters, while the preset water level change is 0.3 meters.

[0162] Water level difference = real-time water level change - preset water level change = 0.5 m - 0.3 m = 0.2 m.

[0163] Calculate the efficiency difference:

[0164] The real-time drainage efficiency is 80%, while the preset drainage efficiency is 90%.

[0165] Efficiency difference = real-time drainage efficiency - preset drainage efficiency = 80% - 90% = -10%.

[0166] Calculate the reduction in the actual installation area:

[0167] Assume that based on the water level difference and efficiency difference, the reduction value is determined to be 2 actual installation areas.

[0168] The sum of the installation scores of adjacent areas of each actual installation area was calculated and ranked.

[0169] Sort and select the actual installation area to reduce:

[0170] The installation scores and ranking results are as follows:

[0171] Area A: 85 points

[0172] Area B: 75 points

[0173] Area C: 70 points

[0174] Area D: 65 points

[0175] According to the reduction value 2, the first two regions (region C and region D) in the sorting result are selected for reduction.

[0176] Calculate the reduction in initial installation data:

[0177] Assuming that based on the water level difference and efficiency difference, the reduction data is determined to be a 0.2 meter reduction in installation depth and a 5 square meter reduction in cross-sectional area, the initial installation depth and cross-sectional area are adjusted according to the reduction data.
