The embodiment of the application discloses a deep foundation pit supporting structure displacement monitoring device.

Referring to fig. 1 and 2, a displacement monitoring device for a deep foundation pit supporting structure comprises a first monitoring box 1, wherein the first monitoring box 1 is buried underground at the periphery of the supporting structure. One side of the first monitoring box 1 is fixedly provided with a first guide pipe 3, and the first guide pipe 3 is positioned on one side of the first monitoring box 1 far away from the supporting structure.

Referring to fig. 3, a mounting plate 4 is fixedly mounted at one end of the first guide tube 3 far from the first monitoring box 1, and the mounting plate 4 is used for plugging one end of the first guide tube 3 far from the first monitoring box 1, so that the condition that soil enters the first guide tube 3 is reduced. One end of the first guide pipe 3, which is close to the first monitoring box 1, is communicated with the inside of the first monitoring box 1.

Referring to fig. 3, a pressure sensor 5 is fixedly installed on one side of the mounting plate 4 adjacent to the first monitoring tank 1. The first monitoring box 1 is internally provided with a shaft lever 6, and the end part of the shaft lever 6 is rotationally inserted into two opposite inner side walls of the first monitoring box 1. The axostylus axostyle 6 fixed mounting has depression bar 7, and the one end fixed mounting of depression bar 7 has briquetting 8. The depression bar 7 receives the influence of briquetting 8 gravity, when the one end that briquetting 8 was kept away from to the depression bar 7 does not applys external force, briquetting 8 drove the depression bar 7 and rotates, then depression bar 7 is vertical setting, and briquetting 8 is located the below of depression bar 7.

Referring to fig. 3, an elastic mechanism 9 is provided between the pressure block 8 and the pressure sensor 5. The elastic mechanism 9 includes a first guide lever 91, a pressing plate 92, and a spring 93. The pressure plate 92 abuts against the side of the pressure sensor 5 remote from the mounting plate 4. The first guide rod 91 is slidably disposed through the first guide tube 3, and the spring 93 is fixedly mounted between the pressing plate 92 and the first guide rod 91. The pressing rod 7 is rotated, and the pressing rod 7 drives the pressing block 8 to press the first guide rod 91. Then, the first guide rod 91 presses the pressure sensor 5 through the spring 93 and the pressing plate 92, and the spring 93 plays a role in buffering, so that the pressure of the pressure sensor 5 by the pressing block 8 is reduced.

Referring to fig. 3 and 4, a second guide rod 11 is hinged to one end of the compression rod 7, which is far away from the pressing block 8, and a second guide tube 10 is slidably sleeved on the second guide rod 11. The second guide pipe 10 is vertically arranged, and a sliding block 12 is fixedly arranged on the outer side wall of the second guide pipe 10. In the implementation of the application, two sliding blocks 12 are arranged, and one sliding block 12 faces the inner side wall of the first monitoring box 1, which is used for rotationally inserting one end of the shaft rod 6; the other slide block 12 faces the inner side wall of the first monitoring box 1, which is used for the rotary insertion of the other end of the shaft lever 6. The inside wall of the first monitoring box 1 is provided with a sliding groove 13 for sliding the sliding block 12, and the sliding block 12 slides in the horizontal direction inside the sliding groove 13. The outer wall fixed mounting of second stand pipe 10 has haulage rope 14, and the one end that haulage rope 14 kept away from second stand pipe 10 runs through the lateral wall that first monitoring case 1 kept away from first stand pipe 3 in a sliding way, and the one end that haulage rope 14 kept away from second stand pipe 10 is used for being connected with supporting construction.

The support structure pulls the pull rope 14 as the support structure is displaced horizontally.

Lifting and sliding are carried out through the second guide rod 11, so that the condition that the pressing rod 7 rotates to drive the traction rope 14 to incline is reduced. When the pressing rod 7 rotates, the pressing rod 7 drives the pressing block 8 to press the first guide rod 91, so that the first guide rod 91 drives the pressing plate 92 to press the pressure sensor 5 through the spring 93. The horizontal displacement of the support structure is then calculated by the pressure experienced by the pressure sensor 5. The hauling cable 14 keeps pulling the second guiding tube 10 horizontally, thereby being beneficial to improving the accuracy of monitoring the horizontal displacement of the supporting structure.

The distance from one end of the pressing rod 7, which is close to the pressing block 8, to the shaft lever 6 is larger than the distance from the other end of the pressing rod 7 to the shaft lever 6. When the second guide pipe 10 is pulled to move through the traction rope 14 and then drives the pressing rod 7 to rotate, the swinging distance of one end, close to the pressing block 8, of the pressing rod 7 is greater than that of one end, far away from the pressing block 8, of the pressing rod 7, so that the pressure born by the pressure sensor 5 is increased, and the accuracy of monitoring the horizontal displacement of the supporting structure is improved.

Referring to fig. 3 and 5, a protection tube 15 is fixedly installed on one side of the first monitoring box 1 far from the first guide tube 3, and the protection tube 15 is communicated with the inside of the first monitoring box 1. The haulage rope 14 wears to locate protection tube 15, and haulage rope 14 is kept away from the one end fixed mounting of depression bar 7 and is had stopper 16. The limiting block 16 is located at one end of the protection tube 15 far away from the first monitoring box 1. A connecting plate 17 is fixedly arranged on one side, close to the protection tube 15, of the limiting block 16, and the connecting plate 17 is provided with a limiting rod 18. The side wall of the protection tube 15 and the connecting plate 17 are provided with limiting holes 19 through which limiting rods 18 penetrate in a damping manner.

Let stopper 16 support and paste in the one end that protection tube 15 kept away from first monitoring case 1, then gag lever post 18 inserts spacing hole 19 on protection tube 15 and connecting plate 17 to make stopper 16 temporarily fixed in the one end that protection tube 15 kept away from first monitoring case 1. When the limiting block 16 abuts against one end, far away from the first monitoring box 1, of the protection tube 15, the pressure rod 7 is kept in a vertical state.

Referring to fig. 3 and 6, the stopper 16 is provided with a third guide pipe 20, and the third guide pipe 20 is vertically disposed. The pipe body of the third guide pipe 20 is fixedly connected with the supporting structure, the limiting block 16 is located inside the third guide pipe 20, the peripheral side of the limiting block 16 abuts against the inner wall of the third guide pipe 20, and the limiting block 16 slides inside the third guide pipe 20. The third guiding tube 20 is provided with a sliding opening 21 for sliding the traction rope 14 at one side close to the first monitoring box 1.

The supporting structure is influenced by gravity and can be displaced along the vertical direction. When the supporting structure is displaced along the vertical direction, the supporting structure drives the third guide tube 20 to move downwards together, and the limiting block 16 slides in the third guide tube 20 and does not move along with the third guide tube 20, so that the situation that the traction rope 14 is pulled when the supporting structure is displaced vertically is reduced, and the accuracy of detecting the horizontal displacement of the supporting structure is improved. When the supporting structure is horizontally displaced, the supporting structure pulls the limiting block 16 to move through the third guide tube 20, and then the limiting block 16 drives the traction rope 14 to move, so that the pulling distance of the traction rope 14 is equal to the horizontal displacement distance of the supporting structure, and the accuracy of detecting the horizontal displacement of the supporting structure is improved.

Referring to fig. 3 and 6, the bottom end of the third guide tube 20 is fixedly provided with the second monitoring box 2, and the bottom end of the third guide tube 20 is not completely blocked by the second monitoring box 2, so that soil can conveniently enter the third guide tube 20 when the third guide tube 20 descends, and the situation that the limiting block 16 drives the traction rope 14 to descend is reduced.

Referring to fig. 3, the outer bottom wall of the second monitoring tank 2 is gradually raised from the middle to the peripheral side in a tapered shape. When the support structure drives the third guide pipe 20 to descend, the third guide pipe 20 drives the second monitoring box 2 to descend together, and the bottom side of the second monitoring box 2 is conical, so that the second monitoring box 2 can push away soil to descend along with the third guide pipe 20 conveniently.

Referring to fig. 3, a lifting rod 22 is fixedly installed at the bottom side of the stopper 16, and the lifting rod 22 is vertically disposed. The lifting rod 22 penetrates through the top side of the second monitoring box 2 in a sliding mode, and a distance sensor 23 is fixedly installed at one end, far away from the limiting block 16, of the lifting rod 22. The distance sensor 23 irradiates vertically downward, so that the distance sensor 23 detects the distance between the bottom end of the lifting lever 22 and the inner bottom wall of the second monitoring box 2.

Referring to fig. 3 and 7, the wireless analyzer 24 is further included, and the wireless analyzer 24 includes a wireless module 241 and a processing module 242. The processing module 242, the pressure sensor 5 and the distance sensor 23 are all electrically connected to the processing module 242. The pressure sensor 5 is used for generating a pressure signal according to the received pressure and sending the pressure signal to the processing module 242, and the distance sensor 23 is used for generating a distance signal according to the distance between the bottom end of the lifting rod 22 and the inner bottom wall of the second monitoring box 2 and sending the distance signal to the processing module 242.

The processing module 242 calculates the pressure to which the pressure sensor 5 is subjected from the pressure signal. The processing module 242 then receives a pressure according to the pressure sensor 5, and the pressure received by the pressure sensor 5 is equal to the elastic force of the spring 93. And then, according to the spring force calculation formula of the spring 93 and the spring force coefficient of the spring 93, the processing module 242 calculates the compression length of the spring 93. The compressed length of the spring 93 is then equal to the distance the press block 8 is displaced horizontally. The processing module 242 obtains the rotation angle of the pressing rod 7 according to the distance from the pressing block 8 to the shaft lever 6. Through the rotation angle of the pressing rod 7, the distance from one end of the pressing rod 7 far away from the shaft lever 6 to the shaft lever 6 is further provided, so that the horizontal movement distance from one end of the pressing rod 7 far away from the shaft lever 6 is calculated, and the horizontal displacement of the supporting structure is calculated.

When the supporting structure is displaced along the vertical direction, the processing module 242 detects the distance from the bottom end of the lifting rod 22 to the inner wall of the second monitoring box 2 according to the distance sensor 23 to form first distance information. After the support structure is displaced in the vertical direction, the processing module 242 detects the distance from the bottom end of the lifting rod 22 to the inner wall of the second monitoring box 2 according to the distance sensor 23 to form second distance information. And calculating the vertical displacement of the supporting structure through the difference value of the first distance information and the second distance information.

The processing module 242 then transmits the horizontal displacement of the support structure along with the vertical displacement to the mobile terminal of the monitoring person. The detection personnel know the horizontal displacement and the vertical displacement of supporting construction through mobile terminal to reduce the frequency that monitoring personnel detected to the job site, and then conveniently monitor foundation ditch supporting construction horizontal displacement.

The implementation principle of the deep foundation pit supporting structure displacement monitoring device is as follows: pit digging is carried out on the bottom surface of the periphery of the foundation pit, and then the monitoring device is put in. And then the limiting rod 18 is inserted into the limiting hole 19 of the connecting plate 17 and the protecting pipe 15, so that the limiting block 16 is temporarily fixed on the protecting pipe 15, and the limiting block 16 abuts against one end, far away from the first monitoring box 1, of the protecting pipe 15. And then placing the limiting block 16 into the third guide pipe 20, and backfilling soil into the third guide pipe 20, so that the situation that the limiting block 16 slides downwards under the action of gravity is reduced. The third guide tube 20 is then fixedly connected to the support structure. When the third guide tube 20 is fixedly connected with the supporting structure, the limiting block 16 is kept connected with the protection tube 15, so that the situation that the limiting block 16 is pulled when the third protection tube 15 is installed on the supporting structure is reduced. After the third protection tube 15 is installed on the supporting structure, the limiting rod 18 is pulled out, soil is backfilled, and the monitoring device is buried underground.

When the supporting structure is horizontally displaced, the supporting structure pulls the traction rope 14 to move together through the third guide tube 20 and the limiting block 16. The pulling rope 14 pulls the second guide tube 10 to move, thereby rotating the pressing rod 7. The pressing rod 7 rotates to drive the pressing block 8 to press the second guide rod 11, and the second guide rod 11 presses the pressure sensor 5 through the spring 93 and the pressing plate 92. The pressure sensor 5 generates a pressure signal according to the received pressure and sends the pressure signal to the wireless analysis mechanism 24, the wireless analysis mechanism 24 calculates the horizontal displacement of the supporting structure according to the pressure signal, and then the wireless analysis mechanism 24 sends the horizontal displacement of the supporting structure to the mobile terminal of the monitoring personnel. Monitoring personnel know the horizontal displacement of supporting construction through mobile terminal to reduce the frequency that monitoring personnel detected to the job site, and then conveniently monitor foundation ditch supporting construction horizontal displacement.

When the support structure is displaced in the vertical direction, the distance detected by the distance sensor 23 is changed, the wireless analysis module calculates the vertical displacement of the support structure according to the distance detected by the distance sensor 23, and then the wireless analysis module sends the vertical displacement to the mobile terminal of a monitoring person, so that the horizontal displacement and the vertical displacement of the support structure can be monitored conveniently and simultaneously.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
