[0054] Furthermore, an angle of 5° is set between the plane mirror 102 and the bonding base 103 , so as to facilitate reflection of the laser emitted by the laser emitter 101 .
[0055] A scissor-type lifting platform 105 is fixedly installed on the upper surface of the laser transmitter 101 . The scissor-type lifting platform 105 is driven by a motor. An angle adjustment base 106 is fixedly connected to the upper surface of the scissor-type lifting platform 105 .
[0056] Furthermore, the scissor-type lifting platform 105 is a vertical lift, and the size and lifting drive mode can be customized according to actual needs, so as to realize the ability to drive the angle adjustment base 106 to perform stable vertical lifting movement.
[0057] The upper surface of the angle adjustment base 106 is rotatably connected to the support arm 107 via a pin shaft, the inner wall of the support arm 107 is rotatably connected to the adjustment arm 108 via a pin shaft, one end of the adjustment arm 108 is rotatably connected to the connecting seat 109 via a pin shaft, and the surface of the connecting seat 109 is fixedly connected to the back side of the scale plate 104.

[0064] When the deformation of the waterstop is monitored, the plane mirror 102 is bonded to the waterstop through an adhesive seat. When the waterstop is subjected to tension and compression, the height and angle of the adhesive base 103 and the plane mirror 102 are driven to change. After the height and angle of the plane mirror 102 change, the laser position reflected from the laser emitter 101 to the scale plate 104 changes. Then, the position of the laser on the scale plate 104 changes, and the deformation of the waterstop is monitored in coordination with the scale on the scale plate 104.
[0065] The data acquisition mechanism 2 consists of a fixed support frame 201, a driving motor 202 installed on the surface of the fixed support frame 201, a lifting and collecting seat 203 slidably connected to the surface of the fixed support frame 201, and an image acquisition camera 204 fixedly installed on the surface of the lifting and collecting seat 203.
[0066] The output shaft of the driving motor 202 is fixedly connected to the driving screw 205 through a coupling, and the surface of the driving screw 205 is threadedly connected to the surface of the lifting collection seat 203.
[0067] A support plate 206 is fixedly connected to the surface of the fixed support frame 201 . The two support plates 206 are symmetrically distributed around the axis of the driving screw 205 .

The two stop guide rods 207 are symmetrically distributed with the axis of the support plate 206 as the center. The surface of the lifting collection seat 203 is slidably sleeved with the surface of the stop guide rod 207 .
[0069] When in use, the driving motor 202 drives the driving screw 205 to rotate, and the driving screw 205 drives the collection lifting seat to move up and down along the surface of the fixed support frame 201 and the stop guide rod 207, driving the image collection camera 204 to move, so that the image collection camera 204 can clearly collect the laser data information on the scale plate 104, and feed it back to the database and analysis software for data analysis.
[0070] By setting up a deformation acquisition device, when in use, the laser emitted by the laser transmitter 101 is reflected onto the scale plate 104 through the plane mirror 102, and real-time acquisition is performed through the image acquisition camera 204, thereby realizing real-time monitoring and acquisition of the deformation of the waterstop belt, and intuitively feeding back to the control system and analysis system through scales and images, thereby achieving a better effect of analyzing the compression uniformity of the waterstop belt.
[0071] Step 4: Build a database. According to the data collected and recorded during the force-controlled synchronous tensioning process, build a comparative analysis database.
[0072] Step 5: Install the waterstop at the structural gap that needs to be waterproofed, ensure that its position is fixed, and connect the force-controlled synchronous tensioning device.
[0073] Furthermore, the waterstop is installed at the structural gap that needs to be waterproofed to ensure that its position is fixed, and a force-controlled synchronous tensioning device is connected to ensure the correct installation and effective tensioning of the waterstop in the structure.
[0074] Step six: Configure the force-controlled synchronous tensioning device and install the tensioning device at both ends of the waterstop and at key points.
[0075] Step 7: Force-controlled synchronous tensioning: Set the initial tension at each point through a multi-point synchronous tensioning control system to ensure uniform force at both ends and the middle point of the waterstop.
[0076] Furthermore, tensioning devices are installed at both ends and key points of the waterstop, and the initial tension at each point is set through a multi-point synchronous tensioning control system to ensure uniform force at both ends and the middle point of the waterstop, effectively avoiding problems such as excessive or small local deformation of the waterstop due to uneven force.
[0077] Step 8: Use the force control feedback mechanism to compare and analyze the sensor data collected in real time during the tensioning process and the data collected by the deformation acquisition device with the database data, and adjust the tension to ensure that the force is evenly distributed during the tensioning process.
[0078] Step nine: Compression uniformity analysis: During the tensioning process, the deformation of the waterstop is monitored in real time through sensors and deformation acquisition devices, and the compression displacement and force conditions are recorded. The compression amount of each part of the waterstop is calculated using analysis software to generate a compression uniformity analysis report.
[0079] Furthermore, when in use, a force control feedback mechanism is used to compare and analyze the sensor data collected in real time during the tensioning process and the data collected by the deformation acquisition device with the database data, so as to adjust the tension in time to ensure that the force is evenly distributed during the tensioning process, thereby ensuring the stability and accuracy of the tensioning process.
[0080] During the tensioning process, the deformation of the waterstop is monitored in real time through sensors and deformation acquisition devices, and the compression displacement and stress conditions are recorded. The compression amount of each part of the waterstop is calculated using analysis software, and a compression uniformity analysis report is generated, achieving process visualization and data traceability, which facilitates effective monitoring and evaluation of construction quality.
[0081] Preferably, by comparing the compression amounts at different positions, it is possible to accurately analyze whether the waterstop is compressed evenly. If uneven compression occurs, the tension distribution can be adjusted in time and retested to ensure that the compression uniformity of the waterstop meets the requirements, thereby ensuring the waterproof performance of the waterstop.
[0082] Specifically, the analysis software uses the finite element software of abaqus engineering simulation to analyze the data. First, according to the actual geometric shape, size and material properties of the waterstop, the corresponding geometric model is created in abaqus, and the model is reasonably meshed to ensure that the mesh quality meets the analysis requirements.
[0083] Then, the material properties of the waterstop are defined, including elastic modulus, Poisson's ratio, yield strength, etc., as well as the contact properties with the surrounding medium (precast concrete pipe gallery), to simulate the stress and deformation behavior of the waterstop under actual working conditions.
[0084] Then, according to the installation and use of the waterstop, the corresponding boundary conditions are set, including fixed end constraints, displacement constraints, load loading, etc., to simulate the stress state of the waterstop under different working conditions.
[0085] Then set the analysis steps, including loading method, loading time, loading amplitude, etc., to simulate the stress change process of the waterstop during construction and use.
[0086] Finally, after completing the above settings, submit the analysis task. Abaqus will perform finite element calculations based on the set model, materials, boundary conditions and analysis steps to obtain the deformation, stress and strain results of the waterstop under different working conditions.
[0087] Deformation calculation: Abaqus uses the finite element method to calculate the node displacement of the waterstop under load, thereby obtaining the overall deformation of the waterstop. The deformation law and uniformity of the waterstop can be analyzed by extracting the displacement data of specific nodes or areas.
[0088] Stress calculation: Based on the calculated node displacement, abaqus can further calculate the stress distribution inside the waterstop. By analyzing the stress cloud diagram and stress data, it can evaluate the stress conditions of the waterstop at different positions and determine whether there are problems such as stress concentration.
[0089] Strain calculation: Calculate the strain distribution of the waterstop to understand the deformation degree and uniformity of the waterstop under load, and provide a basis for evaluating the performance of the waterstop.
[0090] Preferably, by adopting the finite element software of abaqus engineering simulation, it can provide rich post-processing functions, which can intuitively display the deformation, stress and strain results of the waterstop belt, and present them in the form of cloud maps, curves, etc., which is convenient for analysis and evaluation.
[0091] The deformation, stress and strain data of key positions are extracted for quantitative analysis, such as calculating the maximum deformation, maximum stress value, average strain, etc., to evaluate whether the performance of the waterstop meets the design requirements.
[0092] It is possible to compare the analysis results under different working conditions or different design schemes, study the influence of various factors on the compression uniformity of the waterstop, and provide a reference for optimizing the design and construction.
[0093] Step 10: Data analysis and evaluation: Analyze whether the waterstop is compressed evenly by comparing the compression amounts at different locations. If uneven compression occurs, adjust the tension distribution and retest to generate a final compression uniformity report to evaluate the waterproof performance of the waterstop.
[0094] Furthermore, the final compression uniformity report generated can be used to evaluate the waterproof performance of the waterstop, provide authoritative basis for project quality acceptance and subsequent use, and ensure the safety and reliability of the project.
[0095] By accurately simulating actual working conditions including horizontal shear sliding dislocation, the multi-point control system and sensors of the tensioning device can accurately measure and control force. In conjunction with the deformation acquisition device, it is possible to comprehensively collect various data of the tensioning process and build a database. The force control feedback mechanism is used to compare data and adjust the tension, so as to achieve real-time monitoring and calculation of the compression amount of each part of the waterstop to evaluate the compression uniformity, and then evaluate the waterproof performance. This solves the problem that the existing traditional waterstop tensioning method cannot accurately analyze the compression uniformity of the waterstop.
