[0002] Bridge construction monitoring is an important part of ensuring the quality, safety and stability of bridge construction. By monitoring and evaluating the bridge construction process and the status of the bridge structure, necessary safety and quality assurance can be provided for bridge construction. The monitoring content includes monitoring during the construction process, as well as monitoring and evaluation of parameters such as the bearing capacity, deformation, and displacement of the bridge structure during the construction process.

The internal thread of the thread groove 21 is connected with a thread column 22. A semicircular groove 24 is provided at the center of the lower surface of the support plate 23. The thread column 22 is clamped inside the semicircular groove 24. A fixing cylinder 25 is embedded at the four corners of the surface of the support plate 23. The insides of the four fixing cylinders 25 are clamped with pressure sensors 26. The upper surfaces of the four pressure sensors 26 are provided with card slots 28. The insides of the four card slots 28 are plugged with plug blocks 29. The upper ends of the four plug blocks 29 are A semicircular pad 210 is fixedly connected to each of the four plug blocks 29. A snap ring 211 is clamped on the surface of the plug block 29. The snap ring 211 is clamped into the surface of the plug block 29 to lift the height of the semicircular pad 210 so that the gap between the semicircular pad 210 and the recess is compensated. When the surface is deformed, the semicircular pad 210 is squeezed. The semicircular pad 210 squeezes the pressure sensor 26 downward through the snap ring 211, so that the value of the pressure sensor 26 changes. The deformation and sinking strength of the bridge deck can be distinguished according to the values ​​of multiple pressure sensors 26.

[0021] Preferably, the fixing assembly 3 includes a fixing ring 31, which is fixedly sleeved on the surface of the threaded column 22. Two rotation grooves 32 are arranged on the outer wall of the fixing ring 31. The inner walls of the two rotation grooves 32 are fixedly connected with fixing shafts 33. Special-shaped rotation strips 34 are rotatably connected on the surfaces of the two fixing shafts 33. The lower ends of the two special-shaped rotation strips 34 are clamped with U-shaped blocks 35. The two U-shaped blocks 35 are symmetrically fixedly connected to the outer wall of the column 1. Rotating the two special-shaped rotation strips 34 drives the fixing ring 31 to rotate. When the fixing ring 31 rotates, it drives the threaded column 22 to rotate, and the threaded column 22 is pushed upward through the threaded groove 21. The support plate 23 is pushed upward through the threaded column 22, so that the support plate 23 drives the fixing cylinder 25 to move upward.

[0025] Specifically, when using the utility model, first fix the column 1 to the bottom of the bridge deck, then clamp the support plate 23 on the top of the threaded column 22, so that the support plate 23 is close to the bottom of the bridge deck, and rotate the two special-shaped rotating strips 34 to drive the fixing ring 31 to rotate. When the fixing ring 31 rotates, it drives the threaded column 22 to rotate, and the threaded column 22 is pushed up through the threaded groove 21. The support plate 23 is pushed up through the threaded column 22, so that the support plate 23 drives the fixing cylinder 25 to move up, and the fixing cylinder 25 drives the pressure sensor 26 to move up, and the pressure sensor 26 drives the semicircular pad 210 to contact the bottom of the bridge deck. When there is a depression at the bottom of the bridge deck, the plug block 210 is pushed to the bottom of the bridge deck. The surface of 29 is snapped into the snap ring 211, and the height of the semicircular pad 210 is lifted by the snap ring 211, so that the gap between the semicircular pad 210 and the depression is compensated, and the semicircular pad 210 is squeezed when the surface is deformed. The semicircular pad 210 squeezes the pressure sensor 26 downward through the snap ring 211, so that the value of the pressure sensor 26 changes. The deformation and sinking strength of the bridge deck can be distinguished according to the values ​​of multiple pressure sensors 26, so that the multiple pressure sensors 26 set on the same plane can maintain an accurate waiting to be triggered state, so that the accuracy of the data detected by each pressure sensor 26 can be guaranteed.
