[0002] With the continuous advancement of urban underground space development, the upper open-type bundled pipe curtain construction method has been widely used in projects such as subway construction and underground passage construction. However, during the construction process, due to factors such as soil disturbance and structural stress changes, the existing structural floor is prone to local settlement risks, which may in turn cause the risk of deflection of the overall structure, seriously threatening the safety and normal use of the existing structure.

[0003] In the prior art, traditional monitoring and control methods are difficult to respond to such complex situations accurately and timely. Therefore, the present application monitors the settlement of each monitoring area on the bottom plate of the existing structure in real time, identifies the potential risk areas on the bottom plate of the existing structure that may experience significant settlement, and is used to evaluate the overall settlement risk status of the bottom plate of the existing structure, and promptly issues risk warning signals. Based on the risk warning signals, a linear trend analysis is performed on multiple potential risk areas to obtain linear analysis results, and a corresponding fitted warning line is constructed to obtain the remaining adjustment time. Based on the remaining adjustment time, the real-time monitoring values ​​of multiple potential risk areas are combined to calculate the average value to obtain the required jacking distance, and the emergency adjustment value is calculated through a formula to obtain the emergency adjustment amount, and the original jacking speed is adjusted to solve the problem of the risk of deflection of the overall structure caused by the settlement risk in the local area of ​​the bottom plate of the existing structure. Summary of the invention

[0004] The object of the present invention is to provide an automatic compensation system for the settlement and deflection of the underpass structure of the upper opening type bundled pipe curtain, so as to solve at least one of the above-mentioned problems of the prior art.

If the assessment risk value is greater than the assessment risk threshold, a risk warning signal is generated; Emergency analysis module: Based on the risk warning signal, the settlement trend analysis is performed on multiple potential risk areas to obtain the Pearson coefficient. Based on the Pearson coefficient, a linear correlation analysis is performed to output the warning emergency value, which is compared with the warning emergency threshold to obtain the warning emergency signal; Emergency processing module: Based on the early warning emergency signal, obtain the urgent adjustment value and adjust the original jacking speed.

[0006] Beneficial effects of the present invention: 1. The present invention divides monitoring nodes at equal time intervals within the settlement monitoring cycle, uses the settlement measuring points in each monitoring area to obtain the settlement amount and draw a unit real-time monitoring curve, sets the settlement threshold and the warning value, intercepts the real-time monitoring sub-curve between the two, analyzes and determines the potential risk area, analyzes the quantity and potential risk degree of the potential risk area, and conducts a potential settlement risk assessment on the existing structure floor. It not only identifies the potential risk area on the existing structure floor where significant settlement may occur, and provides accurate location information for subsequent targeted treatment measures, but also further analyzes the potential risk area on the existing structure floor, and through quantitative risk assessment, comprehensively understands the overall settlement risk status of the existing structure floor, and issues a risk warning signal in a timely manner; 2. The present invention extracts the corresponding real-time monitoring sub-curves for multiple potential risk areas, calculates the fitting reference slope and equation of the line connecting the two end points of the real-time monitoring sub-curve, and uses the Pearson coefficient to perform linear analysis on the real-time monitoring sub-curve to obtain linear analysis results. Based on the linear analysis results, fitting warning lines are respectively constructed to obtain warning emergency values, thereby reflecting the remaining adjustment time according to the warning emergency values, improving the initiative and timeliness of coping with subsidence risks, and facilitating early planning and timely implementation of effective adjustment measures; 3.

[0012] Embodiment 3 Figure 4 A flow chart of an automatic compensation method for settlement and deflection of an underpass structure of an upper open-type bundled pipe curtain provided in the first embodiment of the present invention. The embodiment of the present invention can be applied to identify whether there are potential settlement risks in multiple monitoring areas on the bottom plate of an existing structure. The automatic compensation method for settlement and deflection of an underpass structure of an upper open-type bundled pipe curtain can be performed by an automatic compensation system for settlement and deflection of an underpass structure of an upper open-type bundled pipe curtain. The automatic compensation system for settlement and deflection of an underpass structure of an upper open-type bundled pipe curtain can be implemented by software and / or hardware. The automatic compensation system for settlement and deflection of an underpass structure of an upper open-type bundled pipe curtain can be configured in an automatic compensation device for settlement and deflection of an underpass structure of an upper open-type bundled pipe curtain. Optionally, the automatic compensation device for settlement and deflection of an underpass structure of an upper open-type bundled pipe curtain can be an electronic device, which can be a notebook, a desktop computer, a smart tablet, etc. The embodiment of the present invention does not limit this.

[0013] like Figure 4 As shown, the automatic compensation method for the settlement and deflection of the underpass structure of the upper opening type bundled pipe curtain provided by the embodiment of the present invention specifically includes the following steps: Step 1: During the settlement monitoring period, multiple monitoring areas on the existing structure bottom plate are monitored in real time to obtain settlement monitoring data, wherein the settlement monitoring data includes the settlement amount, and settlement prediction analysis is performed on the settlement monitoring data to obtain potential risk areas; It should be noted that a settlement measuring point is set up in each monitoring area, and the monitoring area is monitored in real time through the settlement measuring point; In some embodiments, the settlement monitoring period is divided into a number of monitoring nodes, and a monitoring area is arbitrarily selected to obtain the settlement amount of the settlement measuring point on the monitoring node in real time, and a two-dimensional coordinate system is established, where the X-axis is time and the Y-axis is settlement amount. The settlement amount obtained in real time is marked in the two-dimensional coordinate system in turn according to the time sequence of the monitoring node to obtain a unit real-time monitoring curve; It should be noted that the settlement monitoring period is divided in such a way that the settlement monitoring period is divided into equal time intervals; On the unit real-time monitoring curve, the sedimentation threshold is marked on the Y axis, and a straight line parallel to the X axis is drawn with it as the starting point as the sedimentation threshold line; On the unit real-time monitoring curve, mark the settlement warning value on the Y axis, and use it as the starting point to draw a straight line parallel to the X axis as the settlement warning line; It should be noted that the sedimentation threshold is set by professionals in this field based on experience and is an empirical value; The settlement warning value is set in the force sensor by professionals in this field based on experience. It is an empirical warning value, and the settlement warning value is less than the settlement threshold value. The real-time monitoring curves of some units located above the settlement warning line and below the settlement threshold line are intercepted as real-time monitoring sub-curves; Obtaining coordinate points on the real-time monitoring sub-curve, and performing real-time distance measurement between the coordinate points on the real-time monitoring sub-curve obtained in real time and the settlement threshold line to obtain real-time monitoring values; The real-time monitoring value is compared with the real-time monitoring threshold. The process is as follows: If the real-time monitoring value is greater than or equal to the real-time monitoring threshold, a potential analysis signal is generated; If the real-time monitoring value is less than the real-time monitoring threshold, the real-time monitoring distance measurement is continued; It should be noted that the real-time monitoring threshold is obtained by subtracting the settlement threshold from the settlement warning value; Based on the potential analysis signal, the length of the real-time monitoring sub-curve is extracted, and the ratio is calculated with the total length of the unit real-time monitoring curve to obtain the real-time analysis length; It can be understood that the meaning of the real-time analysis length is: the proportion of the length of the divided real-time monitoring sub-curve to the total length of the unit real-time monitoring curve is calculated to obtain the real-time analysis length. Specifically, it reflects the proportion of the time that the settlement amount in the monitoring area is between the warning value and the threshold value in the entire monitoring cycle time, which can be used to assist in evaluating the proportion of the time that the monitoring area is in a potential risk state during the entire monitoring cycle, and then provide a reference for judging whether the monitoring area is a potential risk area. Divide the real-time monitoring sub-curve according to the length of the equal sub-curve to obtain several analysis sub-curves; Connect the two endpoints of the analysis sub-curve and calculate using the slope calculation formula to obtain the slope of the analysis sub-curve; The slopes of all the analysis sub-curves are added and averaged to obtain the real-time analysis change value; It can be understood that the real-time analysis change value means that the slope of the divided analysis sub-curve is calculated by summing up the average value, which reflects the average rate of change of the settlement amount over time in the monitoring area during the period from the warning value to the threshold value. It can be used to evaluate the change trend characteristics of the monitoring area under this settlement state, and then provide a reference for the analysis and judgment of potential risk areas. The real-time analysis change value is added to the real-time analysis length to obtain a potential analysis value; It can be understood that the potential analysis value means: it reflects the settlement trend and severity of the monitoring area, the real-time analysis length reflects the proportion of time that the area is in a state that may cause a large settlement risk within a certain monitoring period, and the real-time analysis change value reflects the average change speed of settlement within this risk range; The potential analysis value is compared to the potential analysis threshold as follows: If the potential analysis value is greater than the potential analysis threshold, it means that the analyzed monitoring area has a high risk of significant subsidence in the future, and the analyzed monitoring area is marked as a potential risk area; If the potential analysis value is less than or equal to the potential analysis threshold, it means that the risk of significant subsidence in the analyzed monitoring area in the future is low, and the analyzed monitoring area is marked as a non-potential risk area; Step 2: Based on the potential risk area, the potential settlement risk of the existing structure bottom plate is assessed to obtain potential assessment data, wherein the potential assessment data includes the potential risk quantity and the potential risk degree. The potential assessment data is calculated and processed to output an assessment risk value, which is compared with the assessment risk threshold. If the assessment risk value is greater than the assessment risk threshold, a risk warning signal is generated; In some embodiments, the number of potential risk areas on the existing structure floor is obtained, and the ratio is calculated with the total number of monitoring areas on the existing structure floor to obtain the number of potential risks; It can be understood that the potential risk quantity means: obtaining the proportion of the potential risk area to the total number of monitoring areas on the existing structure bottom plate, specifically, reflecting the proportion of all potential risk areas on the existing structure bottom plate; Extract the real-time monitoring value corresponding to the potential risk area, and calculate the ratio with the real-time monitoring threshold to obtain the potential degree value; The potential degree values ​​corresponding to all potential risk areas are summed and averaged to obtain the overall degree value; It can be understood that the overall degree value means: the potential degree values ​​corresponding to all potential risk areas are summed up and averaged. Specifically, it reflects the average risk degree of all potential risk areas on the existing structure floor. The overall degree value is multiplied by the number of potential risks to obtain the assessed risk value; The assessed risk value is compared with the assessed risk threshold as follows: If the assessed risk value is greater than the assessed risk threshold, it means that the number of potential risk areas on the existing structure floor accounts for a large proportion and the potential risk level is high, and a risk warning signal is generated; If the assessment analysis value is less than or equal to the assessment risk threshold, it means that the number of potential risk areas on the existing structure floor is small and the potential risk level is low, and a continuous monitoring signal is generated; The specific implementation method of the embodiment of the present invention is as follows: the monitoring nodes are divided at equal time intervals within the settlement monitoring period, the settlement measurement points in each monitoring area are used to obtain the settlement amount and draw a unit real-time monitoring curve, and by setting the settlement threshold and the warning value, the real-time monitoring sub-curve between the two is intercepted for analysis to determine the potential risk area, and the potential risk area is analyzed based on the quantity and potential risk degree, and the potential settlement risk of the existing structure base plate is evaluated. Not only the potential risk area on the existing structure base plate where significant settlement may occur is identified, and accurate location information is provided for subsequent targeted treatment measures, but also the potential risk area on the existing structure base plate is further analyzed, and through quantitative risk assessment, the overall settlement risk status of the existing structure base plate is fully understood, and risk warning signals are issued in time.

[0014] Embodiment 4 Step 3: Based on the risk warning signal, conduct a settlement trend analysis on multiple potential risk areas to obtain the Pearson coefficient, perform a linear correlation analysis based on the Pearson coefficient, output the warning emergency value, and compare it with the warning emergency threshold. If the warning emergency value is less than the warning emergency threshold, generate a warning emergency signal; Exemplarily, a potential risk area is arbitrarily obtained, and a real-time monitoring sub-curve corresponding to the potential risk area is extracted; Get the two endpoints of the real-time monitoring sub-curve, connect the two endpoints to get the fitting reference straight line, and substitute the endpoint coordinates corresponding to the two endpoints into the slope calculation formula: , and obtain the fitting reference slope , where n represents the total number of potential risk areas, Represents the starting coordinates of the real-time monitoring sub-curve, Represents the end point coordinates of the real-time monitoring sub-curve, It is expressed as the Y-axis coordinate within the starting coordinate of the real-time monitoring sub-curve. It is expressed as real-time monitoring of the Y coordinate of the end point of the sub-curve. It is expressed as the X-axis coordinate within the starting coordinate of the real-time monitoring sub-curve. It is expressed as the X coordinate within the coordinates of the end point of the real-time monitoring sub-curve; Based on the fitted reference slope , monitor the coordinates of the two endpoints of the sub-curve in real time and obtain the fitting reference equation: ,in, The Y-axis coordinate calculated for the fitted reference equation, is a constant; Based on the fitting reference straight line, the real-time monitoring sub-curve is linearly analyzed by the Pearson coefficient. The process is as follows: S1, obtain the coordinates of other data points on the real-time monitoring sub-curve except the endpoints, set as ( , ), =1, 2, 3, ... m, where m is the number of data points excluding the endpoints; S2, calculate the mean of the X coordinates and calculate the mean of the Y coordinates ; S3, calculate the covariance of X and Y ; Calculate the standard deviation of X , calculate the standard deviation of Y ; S4, according to the Pearson coefficient formula , calculate the Pearson coefficient r; It can be understood that if r is close to 1, it means that the real-time monitoring sub-curve has a strong positive linear correlation with the fitting line, and it is a positive linear sub-curve; if r is close to -1, it means that the real-time monitoring sub-curve has a strong negative linear correlation with the fitting line, and it is a negative linear sub-curve; if r is close to 0, it means that the linear correlation between the real-time monitoring sub-curve and the fitting line is very weak, and it is a nonlinear sub-curve; Subtract the Pearson coefficient r from 0 to get the linear determination value, and compare it with the linear determination threshold. The process is as follows: If the linear determination value is greater than the linear determination threshold, the real-time monitoring sub-curve is a linear sub-curve; If the linear determination value is less than or equal to the linear determination threshold, the real-time monitoring sub-curve is a nonlinear sub-curve; It should be noted that the linear determination threshold is set by professionals in this field based on experience and is an empirical value; If the real-time monitoring sub-curve is a nonlinear sub-curve, the slopes of all the analysis sub-curves are compared, the maximum slope of the analysis sub-curve is extracted, and combined with the end point of the real-time monitoring sub-curve, a fitting warning line intersecting the settlement threshold line is made; If the real-time monitoring sub-curve is a linear sub-curve, a fitting warning line intersecting the sedimentation threshold line is made based on the real-time analysis change value and the end point of the real-time monitoring sub-curve; Obtain the X coordinate of the intersection point between the fitted warning line and the settlement threshold line, as well as the X coordinate of the end point of the real-time monitoring sub-curve, and perform subtraction to obtain the absolute value to obtain the emergency duration; The variance of the emergency durations corresponding to multiple potential risk areas is calculated to obtain the duration fluctuation value; The duration fluctuation value is compared with the duration fluctuation threshold, and the process is as follows: If the duration fluctuation value is greater than the duration fluctuation threshold, it means that the emergency duration fluctuations between multiple potential risk areas are large, and a large duration fluctuation signal is generated; If the duration fluctuation value is less than or equal to the duration fluctuation threshold, it means that the emergency duration fluctuations between multiple potential risk areas are small, and a small duration fluctuation signal is generated; It should be noted that the duration fluctuation threshold is set by professionals in this field based on experience and is an empirical value; Based on the large signal of time-length fluctuation, the Pearson coefficient corresponding to the potential risk area is obtained, and the sum is added to obtain the Pearson sum value; The emergency duration corresponding to the potential risk area is calculated by ratio with the Pearson sum value to obtain the weight coefficient; The emergency duration corresponding to the potential risk area is multiplied by the corresponding weight coefficient, and the sum is added to obtain the early warning emergency value; Based on the small signal of duration fluctuation, the corresponding emergency durations of multiple potential risk areas are summed and averaged to obtain the early warning emergency value; It can be understood that the meaning of the early warning emergency value is: an indicator that measures the average remaining time buffer degree of the overall distance to the settlement threshold by comprehensively considering the settlement trends of multiple potential risk areas. Specifically, if the early warning emergency value is larger, it means that there is still a relatively long time to reach the settlement threshold overall, and the situation is relatively less urgent. If the early warning emergency value is smaller, it means that the overall distance to the settlement threshold is closer, and emergency measures need to be initiated as soon as possible to deal with the possible greater settlement risk; Compare the warning emergency value with the warning emergency threshold. The process is as follows: If the warning emergency value is greater than or equal to the warning emergency threshold, it means that there is sufficient remaining adjustment time and a normal adjustment signal is generated; If the warning emergency value is less than the warning emergency threshold, it means that the remaining adjustment time is urgent, and a warning emergency signal is generated; The specific implementation plan of the embodiment of the present invention is: extract the corresponding real-time monitoring sub-curves for multiple potential risk areas, calculate the fitting reference slope and equation of the line connecting the two endpoints of the real-time monitoring sub-curve, and use the Pearson coefficient to perform linear analysis on the real-time monitoring sub-curve to obtain linear analysis results. Based on the linear analysis results, fitting warning lines are constructed respectively to obtain warning emergency values, so as to reflect the remaining adjustment time according to the warning emergency values, improve the initiative and timeliness of responding to subsidence risks, and help to plan in advance and implement effective adjustment measures in a timely manner.

[0015] Embodiment 5 Step 4: Based on the early warning emergency signal, obtain the urgent adjustment value, and adjust the original jacking speed according to the urgent adjustment value to solve the problem of the risk of deflection of the overall structure caused by the risk of settlement in the local area of ​​the existing structure bottom plate; In some embodiments, the real-time monitoring values ​​corresponding to the multiple potential risk areas are summed and averaged to obtain the required lifting distance; Substitute the required lifting distance and the warning emergency value into the formula, through the formula: , calculate the expedited adjustment value ,in, Expressed as the required lifting distance, It is expressed as the warning emergency value; Subtract the expedited adjustment value from the original lifting speed to obtain the expedited adjustment amount; The specific implementation method of the embodiment of the present invention is as follows: the required jacking distance is obtained by averaging the real-time monitoring values ​​of multiple potential risk areas, and then combined with the early warning emergency value, the emergency adjustment value is calculated through a formula to obtain the emergency adjustment amount, and the original jacking speed is adjusted. This helps to promptly correct the deflection trend of the structure caused by local settlement risks, and solve the problem of deflection risks of the overall structure caused by settlement risks in local areas of the bottom plate of the existing structure.
