Description

Technical Field

[0001] This invention relates to the field of data processing technology, and in particular to a closed-loop monitoring method for the verticality of ultra-high vertical concrete formwork. Background Technology

[0002] In the construction of ultra-high vertical concrete structures, such as the core tube of ultra-high-rise buildings and large silos, traditional formwork support devices have a fundamental defect: their purely mechanical structure cannot autonomously detect hidden risks such as load distribution imbalance, adjustment lag and foundation disturbance.

[0003] Existing technologies rely on manual experience for verticality correction. They lack real-time monitoring methods to capture uneven distribution of lateral pressure on the template and cannot quantify the cumulative impact of horizontal swaying on verticality. The adjustment action depends entirely on manual operation of turnbuckles, lacking a linkage verification mechanism between theoretical and actual displacement, making it difficult to guarantee the effectiveness of the correction.

[0004] Especially for dynamic working conditions such as foundation instability and sudden load changes, traditional devices have neither early warning capabilities nor automatic handling functions. There are monitoring blind spots and response breaks throughout the construction process, resulting in frequent quality problems such as formwork bulging and verticality deviations, which cannot be corrected in a closed loop.

[0005] In summary, existing traditional support devices suffer from technical problems such as insufficient adjustment range, node instability, and delayed response. Summary of the Invention

[0006] In response to the above-mentioned defects or improvement needs of existing technologies, this invention provides a closed-loop monitoring method for the verticality of ultra-high vertical concrete formwork, which is used to solve the technical problems of insufficient adjustment range, node instability and delayed response of existing traditional support devices.

[0007] To achieve the above objectives, this invention provides a closed-loop monitoring method for the verticality of ultra-high vertical concrete formwork. The method is applied to a formwork support adjustment device, which includes a connecting formwork assembly, a formwork correction and adjustment assembly, a force transmission and expansion adjustment assembly, and a foundation connector connected in sequence. The method includes:

[0008] A micro-strain gauge array captures the temporal distribution of lateral pressure exerted on the wall template by the connecting template assembly based on a pre-set monitoring window. The micro-strain gauge array is pre-embedded in the weld area of ​​the connecting template assembly. Based on the temporal distribution of lateral pressure, a symmetry analysis of the weld node load in the weld area is performed, outputting a template lateral pressure distribution state signal. The template lateral pressure distribution state signal is analyzed to output a screw thread compensation amount. During the process of adjusting the template correction and adjustment assembly by driving a servo motor according to the screw thread compensation amount, a displacement sensor is activated to obtain the actual displacement of the template correction and adjustment assembly. The displacement sensor is integrated inside the cavity of the template correction and adjustment assembly. A correction action is judged by comparing the actual displacement and the screw thread compensation amount. If the actual displacement does not meet the screw thread compensation amount, the correction action fails, triggering a tie bolt re-tightening command. If the actual displacement meets the screw thread compensation amount, the correction action succeeds, triggering the micro-strain gauge array to monitor and track the offset of the lateral pressure distribution.

[0009] In one implementation, the following processing is also performed:

[0010] During the process of the micro-strain gauge array capturing the lateral pressure time-series distribution, the driving accelerometer monitors the real-time horizontal sway acceleration of the foundation connector, wherein the accelerometer is pre-deployed at the geometric center of the foundation connector; the real-time sway scale of the real-time horizontal sway acceleration is calculated; if the real-time sway scale exceeds the preset acceleration duration by 200ms and the actual displacement meets the screw buckle compensation amount, then a foundation instability alarm is triggered.

[0011] In one embodiment, based on the lateral pressure time-series distribution, a load symmetry analysis of the weld joint in the weld region is performed, and a template lateral pressure distribution state signal is output. The following processing is also performed:

[0012] Based on the symmetry of the sensor deployment, the micro-strain gauge array is divided into N symmetrical monitoring units. N sets of lateral pressure time-series data are extracted from the lateral pressure time-series distribution mapping according to these N symmetrical monitoring units. Based on the spatial deployment characteristics of the N symmetrical monitoring units, the time-series deviation characteristics of the N sets of lateral pressure time-series data are fused and calculated to output the global load deviation rate and global load deviation gradient. Based on the joint threshold determination of the global load deviation rate and global load deviation gradient, output signal matching is performed to generate the template lateral pressure distribution state signal.

[0013] In one implementation, based on the spatial deployment characteristics of the N sets of symmetrical monitoring units, the time-series deviation characteristics of the N sets of lateral pressure time-series data are fused and calculated to output the global load deviation rate and the global load deviation gradient. The following processing is also performed:

[0014] Based on the N sets of lateral pressure time-series data, N time-series deviation rate sequences are calculated; according to the data acquisition time sequence, the N time-series deviation rate sequences are fused using the exponential smoothing method to output N load deviation rates; based on the distance characteristics between the N sets of symmetrical monitoring units and the center of the welding area, the N load deviation rates are weighted and fused to output the global load deviation rate; after calculating N load deviation gradients based on the N time-series deviation rate sequences, the N load deviation gradients are weighted and fused based on the distance characteristics between the N sets of symmetrical monitoring units and the center of the welding area to output the global load deviation gradient.

[0015] In one implementation, based on the joint threshold determination of the global load deviation rate and the global load deviation gradient, output signal matching is performed to generate the template side pressure distribution state signal, and the following processing is also performed:

[0016] The system presets a deviation rate threshold, a deviation gradient threshold, and an adjacent node deviation threshold. If the global load deviation rate does not meet the deviation rate threshold, and / or the global load deviation gradient does not meet the deviation gradient threshold, a lateral pressure uneven distribution signal is output. If the global load deviation rate meets the deviation rate threshold, and the global load deviation gradient meets the deviation gradient threshold, the system retrieves the N load deviation rates to perform adjacent node deviation comparison. If the system iterates through the N load deviation rates and counts M adjacent welded nodes whose load deviation rates meet the adjacent node deviation threshold, a systematic tilting cause signal is output, where M≤3.

[0017] In one embodiment, after analyzing the template side pressure distribution state signal to output the screw buckle compensation amount, the following processing is also performed:

[0018] If the template lateral pressure distribution status signal type is the uneven lateral pressure distribution signal, then the global load deviation rate is extracted; lateral pressure unevenness compensation calculation is performed based on the global load deviation rate, and the spiral buckle compensation amount is output; if the template lateral pressure distribution status signal type is the systematic tilting cause signal, then the maximum load deviation rate of the exceeding node and the number of exceeding nodes are extracted; the maximum load deviation rate of the exceeding node and the number of exceeding nodes are used to match and output the spiral buckle compensation amount in the compensation information database.

[0019] In one implementation, if the real-time swaying scale exceeds the preset acceleration duration by 200ms and the actual displacement does not meet the screw buckle compensation amount, then a composite working condition handling action is triggered simultaneously.

[0020] In one implementation, the combined working condition handling actions include load unevenness compensation and foundation instability handling.

[0021] In one embodiment, if the micro-strain gauge array performs lateral pressure distribution offset monitoring and tracking, and the load deviation rate decreases by less than 2% across W monitoring windows, then secondary compensation is triggered.

[0022] In one embodiment, if the micro-strain gauge array performs lateral pressure distribution offset monitoring and tracking, and the load deviation rate in P monitoring windows is less than 1 / Q of the deviation rate threshold, then a verticality acceptance signal is generated.

[0023] One or more technical solutions provided in this invention have at least the following technical effects or advantages:

[0024] The method provided in this invention captures the temporal distribution of lateral pressure on the wall template by a micro-strain gauge array based on a pre-set monitoring window. The micro-strain gauge array is pre-embedded in the weld area of ​​the connecting template assembly. Based on the temporal distribution of lateral pressure, the symmetry of the weld node load in the weld area is analyzed, and a template lateral pressure distribution state signal is output. The template lateral pressure distribution state signal is analyzed to output a screw thread compensation amount. During the process of adjusting the template correction and adjustment assembly by driving a servo motor according to the screw thread compensation amount, a displacement sensor is activated to obtain the actual displacement of the template correction and adjustment assembly. The displacement sensor is integrated inside the cavity of the template correction and adjustment assembly. A correction action is judged by comparing the actual displacement and the screw thread compensation amount. If the actual displacement does not meet the screw thread compensation amount, the correction action fails, triggering a tie bolt re-tightening command. If the actual displacement meets the screw thread compensation amount, the correction action succeeds, triggering the micro-strain gauge array to monitor and track the offset of the lateral pressure distribution. This achieves the technical effect of millimeter-level precise verticality monitoring and maintenance without human intervention throughout the entire construction process of continuous pouring of ultra-high vertical concrete structures.

[0030] This invention provides a closed-loop monitoring method for the verticality of ultra-high vertical concrete formwork, addressing the technical problems of insufficient adjustment range, node instability, and delayed response in existing traditional support devices. It achieves millimeter-level precise verticality monitoring and maintenance without human intervention throughout the entire construction process of continuous pouring of ultra-high vertical concrete structures.

[0034] The flowchart of the closed-loop monitoring method for the verticality of ultra-high vertical concrete formwork provided in this embodiment of the invention is shown below. Figure 1 .

[0035] The method is applied to a template support adjustment device; the overall structure of the template support adjustment device is described below. Figure 2 Furthermore, it should be understood that the installation of the template support adjustment device on both sides of the ultra-high vertical concrete template is symmetrical; see the enlarged view of a single side of the device for details. Figure 3The template support adjustment device includes a connecting template assembly 1, a template correction and adjustment assembly 2, a force transmission and expansion adjustment assembly 3, and a base connector 4 connected in sequence.

[0036] The weld area of ​​the connecting template assembly is pre-embedded with a micro-strain gauge array. Specifically, micro-strain gauges are symmetrically deployed on both sides of each weld node, forming the micro-strain gauge array. A high-precision displacement sensor is integrated inside the cavity of the template correction adjustment assembly, which is driven by a servo motor to adjust the template according to the compensation amount of the rigging screw. This high-precision displacement sensor is used to monitor the adjustment displacement of the rigging screw in the template correction adjustment assembly in real time to verify the effectiveness of template correction. The length adjustment of the template correction adjustment assembly is driven by a servo motor. An accelerometer is pre-deployed at the geometric center of the basic connector to monitor horizontal sway caused by wind vibration or pouring impact.

[0037] The specific usage method of the template support adjustment device is as follows: the device is symmetrically deployed on both sides of the upper bolt positions on both sides of the ultra-high vertical concrete template, so that the connecting template assembly is anchored to the tie bolts of the ultra-high vertical concrete template, and the foundation connector is fastened to the concrete base block; after infrared coarse calibration, the screw buckle of the template correction adjustment assembly is used for fine adjustment. During the adjustment process: the micro strain gauge array monitors the lateral pressure distribution in real time. When the load deviation exceeds the standard, the screw buckle compensation is triggered. The displacement sensor verifies the deviation between the theoretical displacement and the actual displacement. If the deviation exceeds the standard, the tie bolts are tightened again. The foundation accelerometer captures the horizontal sway. When the deviation exceeds the standard, the base block is reinforced by grouting. The verticality is controlled in a closed loop throughout the process, which solves the problems of insufficient adjustment range, node instability and response lag of traditional support devices.

[0038] The method described in this embodiment is used to provide closed-loop protection for the template support adjustment device during use when the length of the force transmission telescopic adjustment component is fixed.

[0039] The specific implementation steps of the closed-loop monitoring method for the verticality of ultra-high vertical concrete formwork are as follows:

[0040] Step A100: The micro strain gauge array captures the temporal distribution of the lateral pressure of the connecting template assembly on the wall template based on a preset monitoring window, wherein the micro strain gauge array is pre-embedded in the weld area of ​​the connecting template assembly.

[0041] Specifically, during the construction of ultra-high vertical concrete structures, a micro-strain gauge array pre-embedded in the weld area of ​​the connecting template components captures the temporal distribution data of its lateral pressure on the wall template in real time based on a preset monitoring window, with a sampling frequency of 10Hz.

[0042] By monitoring the stress changes of N welding nodes under the impact of concrete pouring in real time, a continuous load time series curve (lateral pressure time series distribution) is formed, providing original data support for subsequent load symmetry analysis.

[0043] Step A200: Based on the lateral pressure time sequence distribution, perform a load symmetry analysis of the weld joint in the weld area and output the template lateral pressure distribution state signal.

[0044] In one embodiment, based on the lateral pressure time-series distribution, a load symmetry analysis of the weld joint in the weld region is performed, and a template lateral pressure distribution state signal is output. Step A200 of the method provided by this invention further includes:

[0045] Step A210: Based on the symmetry of the sensor layout, the micro strain gauge array is divided into N groups of symmetrical monitoring units.

[0046] Step A220: Extract N sets of lateral pressure time series data from the lateral pressure time series distribution mapping based on the N sets of symmetrical monitoring units.

[0047] Step A230: Based on the spatial deployment characteristics of the N sets of symmetrical monitoring units, perform time-series deviation characteristic fusion calculation on the N sets of lateral pressure time-series data, and output the global load deviation rate and global load deviation gradient.

[0048] Step A240: Based on the joint threshold determination of the global load deviation rate and the global load deviation gradient, perform output signal matching to generate the template side pressure distribution state signal.

[0049] In one embodiment, based on the spatial deployment characteristics of the N sets of symmetrical monitoring units, the time-series deviation characteristics of the N sets of lateral pressure time-series data are fused and calculated to output the global load deviation rate and the global load deviation gradient. Step A230 of the method provided by this invention further includes:

[0050] Step A231: Calculate N time-series deviation rate sequences based on the N sets of lateral pressure time-series data.

[0051] Step A232: Based on the data acquisition time series, fuse the N time series deviation rate sequences using the exponential smoothing method to output N load deviation rates.

[0052] Step A233: Based on the distance characteristics between the N sets of symmetrical monitoring units and the center of the welding area, the N load deviation rates are weighted and fused to output the global load deviation rate.

[0053] Step A234: After calculating N load deviation gradients based on the N time-series deviation rate sequences, the N load deviation gradients are weighted and fused according to the distance characteristics between the N sets of symmetrical monitoring units and the center of the welding area, and the global load deviation gradient is output.

[0054] In one embodiment, based on the joint threshold determination of the global load deviation rate and the global load deviation gradient, output signal matching is performed to generate the template side pressure distribution state signal. Step A240 of the method provided by this invention further includes:

[0055] Step A241: Preset the deviation rate threshold, deviation gradient threshold, and adjacent node deviation threshold.

[0056] Step A242: If the global load deviation rate does not meet the deviation rate threshold, and / or the global load deviation gradient does not meet the deviation gradient threshold, then output a side pressure uneven distribution signal.

[0057] Step A243: If the global load deviation rate meets the deviation rate threshold and the global load deviation gradient meets the deviation gradient threshold, then retrieve the N load deviation rates to perform adjacent node deviation comparison.

[0058] Step A244: If the load deviation rates of the N load deviation rates are traversed and the load deviation rates of the M adjacent welding nodes are counted and meet the adjacent node deviation threshold, then a systematic tilting cause signal is output, where M≤3.

[0059] This embodiment uses the lateral pressure time-series distribution data collected by micro-strain gauges to perform load symmetry analysis of welded nodes, and finally outputs a template lateral pressure distribution state signal that characterizes the template stress imbalance state.

[0060] Specifically, in this embodiment, the strain gauge deployment characteristics in the weld area are as follows: strain gauges are symmetrically deployed at each welding node. Based on this, the micro strain gauge array is divided into N groups of symmetrical monitoring units. Each unit corresponds to a welding node and contains two symmetrically arranged strain gauges for independently monitoring the load distribution on both sides of the node, ensuring the integrity of the data acquisition space coverage.

[0061] Based on the physical location identifiers of N sets of symmetrical monitoring units, corresponding N sets of lateral pressure time-series data are extracted from the lateral pressure time-series distribution data. Each set of data contains the synchronous load values ​​of the symmetrical strain gauges at the same node, forming an independent dataset that strictly matches the location of the welded node, providing structured input for subsequent symmetry analysis.

[0062] Using conventional deviation rate calculation methods, N time-series deviation rate sequences are calculated based on the N sets of lateral pressure time-series data. The time-series deviation rate directly quantifies the degree of nodal load asymmetry.

[0063] An exponential smoothing method (smoothing coefficient α = 0.2) is used to denoise and fuse the N time-series deviation rate sequences of N welding nodes, eliminate vibration pulse interference, and output the smoothed N load deviation rates to improve data stability.

[0064] Weights are assigned based on the distance between the weld node and the center of the weld area (the weight of the center node is doubled). These weighted load deviation rates are then combined to generate the global load deviation rate. It should be understood that the center node, due to the concentration of its heat-affected zone, is more sensitive to load imbalance and therefore requires a higher weight.

[0065] The gradient changes of the load deviation rates of N nodes are calculated, and the global load deviation gradient is generated by fusion according to the distance weight. The global load deviation gradient captures the load mutation rate and is used to distinguish between steady-state imbalance and dynamic impact.

[0066] Preset judgment thresholds: deviation rate threshold 15% (critical value for asymmetrical load growth), deviation gradient threshold 5% / s (upper limit of concrete vibration pulse frequency), and adjacent node deviation threshold 20% (criteria for judging systematic tilt).

[0067] If the global load deviation rate is greater than 15% for 300ms (excluding instantaneous interference), or the global load deviation gradient is greater than 5% / s (dynamic abrupt change), a side pressure distribution unevenness signal is output. The side pressure distribution unevenness signal is used to directly trigger the screw thread compensation adjustment.

[0068] When the global parameters do not exceed the standard (the global load deviation rate meets the deviation rate threshold, and the global load deviation gradient meets the deviation gradient threshold), the N load deviation rates of N welding nodes are retrieved for local scanning, focusing on detecting the cooperative imbalance phenomenon of adjacent node groups.

[0069] If the traversal finds that the load deviation rate of three or more consecutive adjacent nodes is greater than 20% and lasts for 300ms, a systematic tilting cause signal is output. The systematic tilting cause signal triggers reinforcement compensation to suppress the bending moment accumulation effect.

[0070] This embodiment achieves the technical effect of millimeter-level perception and precise location of the cause of template lateral pressure distribution imbalance.

[0071] Step A300: Analyze the template side pressure distribution state signal and output the spiral buckle compensation amount.

[0072] In one implementation, the spiral buckle compensation amount is output by parsing the template side pressure distribution state signal. The method step A300 provided by this invention includes:

[0073] Step A310: If the template side pressure distribution state signal type is the side pressure uneven distribution signal, then extract the global load deviation rate.

[0074] Step A320: Calculate the compensation for uneven lateral pressure distribution based on the global load deviation rate, and output the compensation amount of the spiral buckle.

[0075] Step A330: If the template side pressure distribution state signal type is the systematic tilting cause signal, then extract the maximum load deviation rate of the out-of-standard nodes and the number of out-of-standard nodes.

[0076] Step A340: Use the maximum load deviation rate of the out-of-standard node and the number of out-of-standard nodes to match and output the spiral buckle compensation amount in the compensation information database.

[0077] This embodiment is used to convert the template side pressure distribution state signal generated by load symmetry analysis into a precise adjustment amount of the screw buckle.

[0078] Specifically, pattern recognition is performed on the input signal type. When a signal with uneven lateral pressure distribution is identified (characterized by a global load deviation rate > 15% for 300ms or a deviation gradient > 5% / s), the core parameter in the signal data packet is automatically extracted: the global load deviation rate. The global load deviation rate characterizes the degree of overall load imbalance in the weld area and serves as the benchmark input variable for subsequent compensation actions.

[0079] Based on the extracted global load deviation rate, a screw adjustment command is generated according to a preset compensation conversion algorithm. The dimensionless deviation rate is converted into a millimeter-level displacement through a linear transformation relationship (compensation amount = global load deviation rate × 1.2). The conversion process embeds a dynamic correction factor to compensate for system response lag, ensuring that the output compensation amount can directly drive the servo motor to perform precise displacement correction.

[0080] If the signal type is a systemic tilt cause, i.e., the load deviation rate of ≥3 adjacent nodes >20% is triggered for 300ms, then two key parameters are extracted simultaneously: the maximum load deviation rate of the out-of-standard node (the highest deviation rate value among all out-of-standard nodes, reflecting the most severe imbalance point) and the out-of-standard node count M. The out-of-standard node count is the number of consecutive out-of-standard nodes (M≥3), which characterizes the systemic risk level.

[0081] The maximum load deviation rate of the out-of-standard nodes and the number of out-of-standard nodes are input into the compensation mapping model. The spiral buckle adjustment amount is output through a multi-dimensional query matrix. This mapping model is constructed based on historical working condition data and establishes a nonlinear correspondence between the node imbalance intensity, risk level and compensation amount to achieve enhanced compensation control for systemic tilting conditions.

[0082] Step A400: During the process of adjusting the template correction adjustment component by driving the servo motor according to the spiral buckle compensation amount, the displacement sensor is activated to obtain the actual displacement of the template correction adjustment component, wherein the displacement sensor is integrated inside the cavity of the template correction adjustment component.

[0083] Step A500: By comparing the actual displacement and the screw thread compensation, a correction action is determined.

[0084] Step A600: If the actual displacement does not meet the screw thread compensation amount, the correction action fails and the tie bolt re-tightening command is triggered.

[0085] Step A700: If the actual displacement satisfies the screw thread compensation amount, the correction action is successful, triggering the micro strain gauge array to perform lateral pressure distribution offset monitoring and tracking.

[0086] Specifically, in this embodiment, during the process of the servo motor driving the template correction and adjustment component to perform the adjustment action according to the screw thread compensation amount, the displacement sensor integrated inside the cavity of the component is simultaneously activated to collect the actual displacement data of the screw thread adjustment mechanism in real time. This sensor directly captures the physical displacement changes of the transmission component using a contact or non-contact measurement principle, forming high-precision displacement time-series data, providing a practical basis for subsequent verification of the correction effect.

[0087] The calculation module dynamically compares the actual displacement acquired by the displacement sensor with the theoretical screw thread compensation to determine the effectiveness of the correction action. The comparison process uses a real-time differential algorithm to calculate the cumulative deviation between the actual and target displacement trajectories. If the deviation exceeds a preset tolerance range, the correction is considered failed; otherwise, it is considered successful. The determination result directly triggers the generation of subsequent control commands.

[0088] If the deviation between the actual displacement and the compensation amount of the spiral buckle exceeds the allowable threshold, the current correction action is deemed to have failed. At this time, a tie bolt re-tightening control command is automatically generated. This command includes the target torque value, the position of application, and the execution priority parameters. It is transmitted to the actuator via the industrial bus to drive the intelligent torque wrench to dynamically reinforce the tie bolts connecting the template assembly and the ultra-high vertical concrete template in order to restore the node preload.

[0089] Conversely, when the actual displacement meets the compensation requirements of the screw thread, the correction action is deemed successful, and the micro strain gauge array is activated to enter the offset monitoring and tracking mode, continuously performing the aforementioned steps A100 to A700 to carry out closed-loop monitoring and maintenance of the verticality of the ultra-high vertical concrete formwork.

[0090] This embodiment achieves the technical effect of precise monitoring and maintenance of millimeter-level verticality without human intervention during the continuous pouring of ultra-high vertical concrete structures.

[0091] In one implementation, the method further includes:

[0092] Step A810: During the process of the micro-strain gauge array capturing the lateral pressure time-series distribution, an accelerometer is driven to monitor the real-time horizontal sway acceleration of the base connector, wherein the accelerometer is pre-deployed at the geometric center of the base connector.

[0093] Step A820: Calculate the real-time sway scale of the real-time horizontal sway acceleration.

[0094] Step A830: If the real-time swaying scale exceeds the preset acceleration duration by 200ms, and the actual displacement satisfies the screw buckle compensation amount, then a foundation instability alarm is triggered.

[0095] Specifically, in this embodiment, while the micro-strain gauge array continuously acquires the lateral pressure time-series data of the connecting template assembly, a triaxial accelerometer deployed at the geometric center of the foundation connector is simultaneously activated to monitor the three-dimensional acceleration response of the concrete block under external disturbances (such as wind loads, equipment vibrations, or pouring impacts) in real time. This sensor captures absolute motion characteristics at a 100Hz sampling frequency, forming a high-resolution horizontal sway acceleration time-series dataset.

[0096] The raw time-series signals acquired by the accelerometer are preprocessed: first, high-frequency noise and DC drift are removed by Butterworth bandpass filter to extract the effective sway component; then, the root mean square value (RMS) of the acceleration vector is calculated as a quantitative index of the real-time sway scale. This parameter comprehensively characterizes the instantaneous kinetic energy intensity of the basic connector in three spatial dimensions.

[0097] When the real-time sway RMS value exceeds the preset acceleration threshold (indicating the critical state of foundation instability) for 200ms continuously, and the actual displacement fed back by the displacement sensor meets the screw thread compensation requirement (i.e., the correction action is successful), a foundation instability alarm is automatically triggered. This alarm includes the disturbance intensity level, risk location coordinates, and recommended handling strategies, and is pushed to the construction monitoring center via the Industrial Internet of Things (IIoT) protocol.

[0098] This embodiment achieves the technical effect of millisecond-level early warning of foundation disturbance risk throughout the entire construction process, realizing reliable monitoring of the entire process of ultra-high structure from dynamic construction to static formation.

[0099] In one implementation, if the micro-strain gauge array performs lateral pressure distribution offset monitoring and tracking, and the load deviation rate of P monitoring windows is less than 1 / Q of the deviation rate threshold, then a verticality acceptance signal is generated.

[0100] Specifically, in this embodiment, when the micro strain gauge array enters the lateral pressure offset monitoring and tracking mode, if the load deviation rate is less than 1 / Q of the deviation rate threshold (i.e., δ<15% / Q) for P consecutive monitoring windows, it is determined that the stress state of the template has entered the stable convergence stage, and a verticality acceptance signal is automatically generated to trigger the construction quality acceptance process. At the same time, the current monitoring data is frozen and an encrypted acceptance report is generated.

[0101] In one implementation, if the real-time swaying scale exceeds the preset acceleration duration by 200ms and the actual displacement does not meet the screw buckle compensation amount, then a composite working condition handling action is triggered simultaneously.

[0102] In one implementation, the combined working condition handling actions include load unevenness compensation and foundation instability handling.

[0103] Specifically, in this embodiment, when the quantitative index of real-time horizontal sway acceleration (real-time sway scale) continuously exceeds a set threshold for 200 milliseconds, and the actual displacement fed back by the displacement sensor fails to reach the expected target of the screw thread compensation, it is automatically determined to be a composite working condition (i.e., concurrent foundation instability and adjustment failure). At this time, a multi-task handling protocol is activated simultaneously, and load unevenness compensation and foundation instability handling are executed concurrently. Load unevenness compensation offsets lateral pressure imbalance through secondary fine-tuning of the screw thread; foundation instability handling initiates high-pressure grouting to reinforce the ground anchor blocks and suppress overturning disturbances. The dual actions work together to suppress composite risks and avoid the limitations of single-point handling.

[0104] The specific actions for handling the complex working conditions include load unevenness compensation and foundation instability treatment. Load unevenness compensation refers to generating a helical compensation amount based on the latest load deviation rate, driving a servo motor to perform axial displacement correction. During the adjustment process, displacement sensors track the actual displacement trajectory in real time and dynamically compare it with the theoretical compensation amount until the load distribution returns to a balanced state. Foundation instability treatment involves injecting a specific proportion of grout into the concrete base block, with the grouting volume and pressure adaptively adjusted according to the disturbance intensity. The grouting equipment operates at a stable pressure threshold, while an accelerometer monitors the attenuation of horizontal sway until the foundation returns to a stable threshold.

[0105] In one implementation, if the micro-strain gauge array performs lateral pressure distribution offset monitoring and tracking, and the load deviation rate decreases by less than 2% across W monitoring windows, then secondary compensation is triggered.

[0106] Specifically, in this embodiment, when the micro-strain gauge array enters the lateral pressure distribution offset monitoring and tracking mode, it continuously analyzes the load deviation rate change trend within a preset time window. If the decrease in load deviation rate is less than the set convergence threshold for W consecutive monitoring windows, indicating that the load distribution recovery rate has not met expectations, it is automatically determined that the imbalance state has not effectively converged. At this time, a secondary compensation trigger command is generated to start the supplementary adjustment process of the screw thread.

[0107] After the secondary compensation is triggered, the latest value of the current load deviation rate is called to generate a new screw buckle compensation amount, which drives the servo motor to perform axial displacement correction. During the secondary compensation process, the displacement sensor synchronously tracks the actual displacement response. If the load deviation rate reduction in the next monitoring window after compensation still does not meet the standard, a new round of compensation calculation is triggered iteratively until the load distribution stabilizes and enters the safe threshold range.

[0108] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
