Description

Technical Field

[0001] The present invention relates to the technical field of settlement detection, and in particular to a settlement monitoring device applied to an integrated pipe gallery. Background Art

[0002] The pipeline corridor is the main place for concentrated laying of pipelines. The settlement detection of the pipeline corridor is of great significance to the safe operation of the pipeline corridor. At the same time, the detection data can be directly used to evaluate the impact of the pipeline corridor on the surface environment. The pipeline corridor is generally built in cities with dense population and dense construction facilities. When the pipeline corridor is operated, it will inevitably cause disturbance to the rock and soil, and cause displacement and deformation of the surface around the cavern. When the displacement and deformation exceed a certain limit, it will inevitably endanger the safety of the surrounding ground buildings and facilities and the pipeline corridor itself.

[0003] The current detection method mainly uses static levels and other detection instruments to detect the settlement of the corridor. However, the existing technical detection method can only detect the settlement of the corridor. When the settlement of the corridor, especially when the settlement speed is fast due to factors such as the foundation, it is impossible to prevent or limit the settlement trend of the corridor, and it is impossible to buy time before the emergency repair personnel arrive to carry out maintenance work, resulting in displacement, deformation, and even tearing of the corridor during rapid settlement, which seriously affects the overall structure and life of the corridor.

[0012] Preferably, a connecting valve for connecting the reaction cylinder and the air cavity is provided inside the reinforcement block.

[0013] Preferably, the end of the second clamping block away from the rotating sleeve is designed to be arc-shaped, and the edge portion of the end of the second clamping block located inside the rotating sleeve is designed to be chamfered.

[0017] In summary, the beneficial effects of the present invention are:

[0018] 1. Through the design of the diameter difference between the hydraulic chamber and the detection chamber, the settlement displacement can be amplified and detected when the corridor settles, thereby improving the detection accuracy. In addition, during the settlement, the dilute hydrochloric acid solution in the storage tube is pressurized and pushed into the reaction tube through the piston rod to generate carbon dioxide gas, which increases the pressure inside the gas cavity, pushes the support sleeve upward to make the support block contact the corridor, and provides a reverse thrust for the corridor. In addition, the amount of gas reaction generated in the reaction tube can be controlled according to the settlement amount of the corridor, thereby controlling the size of the reaction force on the corridor. The greater the settlement amount, the greater the reaction thrust provided, and the smaller the settlement amount, the smaller the reaction thrust provided. Not only can a reaction force be provided to reduce the settlement trend when the corridor settles, which is convenient for manual and timely construction treatment, but also the settlement difference can be compensated for differentially when the reaction force is provided, ensuring that the overall structure of the corridor is evenly stressed, and can prevent stress concentration caused by excessive local settlement differences, avoid deformation and tearing of the structure in weak parts, and extend the service life of the corridor.

[0019] 2. When the pipe gallery further settles, the acting force between the supporting sleeve, the supporting block and the pipe gallery continues to increase, the supporting block moves toward the inside of the supporting sleeve, the pressure spring is compressed, and at the same time the supporting block pressurizes the hydraulic oil in the second hydraulic chamber, which can push the piston block to pump the dilute hydrochloric acid solution in the liquid storage chamber into the reaction chamber for reaction. The gas generated by the reaction enters the airbag through the pipeline to expand the airbag, which can not only support and react to the pipe gallery, but also adjust the expansion degree and pressure of the airbag according to the stress generated by the settlement degree, ensuring that different degrees of reaction force and filling pressure are applied to different settlements of the pipe gallery, filling and buffering the foundation at the bottom of the pipe gallery, and effectively avoiding deformation of the pipe gallery and further settlement trend.

[0020] 3. During the process of discharging the gas generated inside the reaction tube, the transmission ring is driven to rotate and accumulate force by driving the rotation of the rotating sleeve. When the rotating sleeve rotates to the position where the second block matches the slot, the transmission ring rotates in the opposite direction to reset, and drives the gear ring to rotate, thereby driving the spiral blade and the stirring blade to accelerate the rotation. When the spiral blade rotates, the calcium carbonate particles at the bottom of the inner side of the reaction tube can be quickly stirred up and mixed with hydrochloric acid, thereby improving the reaction speed and efficiency and avoiding deposition. The axial-flow propeller blades of the stirring blade can still maintain the axial mixing effect when more carbon dioxide gas is produced and the system is relatively disordered during the reaction, thereby preventing the solution from stratifying and ensuring the reaction efficiency.

[0040] Furthermore, a connecting valve 305 is provided inside the reinforcement block 100 to connect the reaction tube 300 and the air cavity 200. It should be noted that the internal flow cross-sectional area of ​​the connecting valve 305 is much smaller than the flow cross-sectional area of ​​the exhaust port 304, and the air pressure between the reaction tube 300 and the air cavity 200 can be connected and balanced at a slow speed, so that the rotating sleeve 302 is reset under the action of the arc spring.

[0041] It should be noted that the end of the second clamping block 310 away from the rotating sleeve 302 is designed to be arc-shaped, and the edge portion of the end of the second clamping block 310 located inside the rotating sleeve 302 is designed to be chamfered.

[0042] Furthermore, the first clamping block 307 is movably sleeved on the outer wall of the transmission ring 308 , and a spring is provided between the first clamping block 307 and the transmission ring 308 , and a chamfer is provided on one side of the first clamping block 307 away from the second clamping block 310 .

[0043] Reference Fig.10 The filling mechanism includes a hydraulic chamber 405 opened inside the supporting sleeve 400, the interior of the hydraulic chamber 405 is sleeved with a supporting block 407, a pressure spring 406 is arranged between the supporting block 407 and the hydraulic chamber 405, and a liquid storage chamber 403 and a reaction chamber 402 are also opened inside the supporting sleeve 400, the liquid storage chamber 403 is communicated with the hydraulic chamber 405, the interior of the liquid storage chamber 403 is sleeved with a piston block 404, a one-way valve is arranged between the reaction chamber 402 and the liquid storage chamber 403, a hose is arranged between the reaction chamber 402 and the airbag 401, calcium carbonate particles are arranged inside the reaction chamber 402, and a dilute hydrochloric acid solution is arranged inside the liquid storage chamber 403 below the piston block 404.

[0044] It should be noted that the liquid storage chamber 403 and the second hydraulic chamber 405 are both cylindrical in design, and the diameter of the second hydraulic chamber 405 is larger than the diameter of the liquid storage chamber 403 .

[0045] The working process of the settlement monitoring device applied to the integrated pipe gallery is as follows:

[0046] During the installation and construction of the pipe gallery, after the installation and leveling of the pipe gallery is completed, the reinforcement blocks 100 are installed symmetrically on both sides of the pipe gallery. When installing the reinforcement blocks 100, the reinforcement blocks 100 are designed to be leveled synchronously with the pipe gallery, and the anchor rods 101 are penetrated into the foundation to ensure the stability of the reinforcement blocks 100. When the pipe gallery sinks, the detection block 202 can be pushed downward, and the piston rod 204 is pushed to move a greater distance in the direction away from the hydraulic chamber 201 through the connection between the hydraulic chamber 1 201 and the detection chamber 205 and the diameter difference between the hydraulic chamber 1 201 and the detection chamber 205. By enlarging the settlement distance, it is not only convenient for inspection The detection accuracy can be improved. When the piston rod 204 moves, the magnetic ring 206 moves synchronously. The displacement of the magnetic ring 206 is synchronously detected by the detection rod 207. By detecting the displacement of the magnetic ring 206, the distance moved by the detection block 202 due to the settlement of the corridor can be detected. It should be noted that the detection rod 207 adopts a high-sensitivity Hall effect linear sensor, which converts the magnetic field change caused by the displacement of the magnetic ring 206 into a measurable electrical signal and monitors it. The settlement distance of different sections of the corridor can be detected by setting the detection rods 207 at different positions.

[0047] It should be noted that the support of the reinforcement blocks 100 on both sides can prevent the tunnel from tilting and settling in the direction of the reinforcement blocks 100, and the independent design of the tunnel and the reinforcement blocks 100 can not only provide support for the foundation around the tunnel, reduce the deformation of the foundation near the tunnel, and share the deformation stress, but also when the tunnel exerts pressure on the bottom foundation, the independently designed reinforcement blocks 100 are less affected, so that the reinforcement blocks 100 are less affected by the settlement of the tunnel and can provide support when the tunnel settles.

[0048] Furthermore, when the piston rod 204 moves, the dilute hydrochloric acid solution in the liquid storage tube 203 can be pressurized and pushed into the reaction cylinder 300 through the discharge port 208 to react with the calcium carbonate particles in the reaction cylinder 300 to generate carbon dioxide gas. As the generated gas increases, the pressure inside the reaction cylinder 300 increases, and enters the sealing ring 301 through the air inlet 303 to push the sealing block 306 and the rotating sleeve 302 to rotate, and compress the arc spring between the sealing block 306 and the reinforcement block 100, and the reaction cylinder 300 is compressed. After the internal air pressure of the reaction tube 300 increases to the point where the sealing block 306 is pushed through the exhaust port 304, the gas inside the reaction tube 300 passes through the air inlet 303 and the inside of the sealing ring 301, and then is discharged into the air cavity 200 through the exhaust port 304. The internal pressure of the air cavity 200 increases, pushing the supporting sleeve 400 upward to make the supporting block 407 contact with the pipe gallery, providing a reverse thrust for the pipe gallery. It should be noted that the displacement of the piston rod 204 is related to the displacement of the detection block 202 due to the settlement of the pipe gallery. The settlement distance of the pipe gallery is The larger the distance, the greater the compression of the hydraulic chamber 201 by pushing the detection block 202 to move, thereby driving the displacement of the piston rod 204 inside the liquid storage tube 203 to be greater, so that the piston rod 204 pumps more hydrochloric acid solution inside the liquid storage tube 203 into the interior of the reaction tube 300 through the discharge port 208, and further makes the amount of gas generated by the reaction of calcium carbonate particles and hydrochloric acid in the reaction tube 300 greater, and then the internal pressure of the air cavity 200 and the reaction thrust of the pipe gallery through the supporting sleeve 400 and the supporting block 407 are greater, so that the amount of gas reaction generated in the reaction tube 300 according to the settlement of the pipe gallery is controlled, and then the size of the reaction force on the pipe gallery is controlled. The greater the settlement, the greater the reaction thrust provided, and the smaller the settlement, the smaller the reaction thrust provided, so as to achieve differentiated compensation for settlement differences, ensure that the overall structure of the pipe gallery is uniformly stressed, prevent stress concentration caused by excessive local settlement differences, avoid deformation and tearing of the structure at weak locations, and extend the service life of the pipe gallery.

[0049] When the rotating sleeve 302 rotates until the sealing block 306 passes over the exhaust port 304 so that the air cavity 200 and the reaction cylinder 300 are connected, the rotating sleeve 302 rotates to drive the second block 310 to rotate, and through the cooperation of the right-angled sides of the second block 310 and the first block 307, the transmission ring 308 is pushed to rotate, driving the reset spring 313 to compress. When the rotating sleeve 302 rotates to the position where the second block 310 cooperates with the slot 317, the first block 307 pushes the second block 310 into the slot 317 through the arc surface of the second block 310, compressing the compression spring 318. At this time, the second block 310 is separated from the restriction and engagement with the first block 307. At this time, the transmission ring 308 rotates in the opposite direction and resets under the elastic force of the reset spring 313, and the transmission ring 30 During the resetting rotation, the ratchet 309 can drive the gear ring 311 to rotate, and the rotation of the gear ring 311 drives the gear 312 to accelerate the rotation, further driving the transmission rod 314 and the spiral blade 315 and the stirring blade 316 arranged on the outer wall of the transmission rod 314 to rotate, so as to realize the accumulation stirring of the calcium carbonate particles and the hydrochloric acid solution mixed material inside the reaction tube 300 during the reaction process. When the spiral blade 315 rotates, the calcium carbonate particles at the bottom of the inner side of the reaction tube 300 can be quickly stirred up and mixed with the hydrochloric acid, thereby improving the reaction speed and efficiency. The axial flow propeller blade of the stirring blade 316 can still maintain the axial mixing effect when more carbon dioxide gas is produced and the system is relatively disordered during the reaction, thereby preventing the solution from stratifying and ensuring the reaction efficiency.

[0050] It should be noted that when the pipeline corridor stops settling, the reaction tube 300 and the air cavity 200 slowly restore balance through the small diameter design of the connecting valve 305, and the rotating sleeve 302 and the sealing block 306 are reset under the elastic force of the arc spring. When the rotating sleeve 302 is reset, the block 2 310 is pushed away from the slot 317 by the elastic force of the compression spring 318, and the chamfered angle design of the block 2 310 facilitates the removal of the block 2 310 from the inside of the slot 317. When the rotating sleeve 302 is reset and rotated until the block 2 310 passes the block 1 307, the block 1 307 can be pushed into the interior of the transmission ring 308 through the bevel of the block 1 307, so as to achieve reset through the block 1 307, which is convenient for subsequent circulation operation.

[0051] When the corridor continues to sink, the pressure provided by the air cavity 200 and the pressure of the corridor sinking cause the force between the supporting sleeve 400, the supporting block 407 and the corridor to continue to increase, and the supporting block 407 moves toward the inside of the supporting sleeve 400, the pressure spring 406 is compressed, and at the same time, the supporting block 407 pressurizes the hydraulic oil in the hydraulic chamber 405. The diameter difference between the liquid storage chamber 403 and the hydraulic chamber 405 can push the piston block 404 to move a longer distance, so that the dilute hydrochloric acid solution in the liquid storage chamber 403 is pumped into the reaction chamber 402 for reaction. The gas generated by the reaction enters the airbag 401 through the pipeline, causing the airbag 401 to expand, which can not only support and react on the corridor, but also fill and compensate for the deformation between the corridor and the foundation through the pressurized expansion of the airbag 401, thereby reducing the settlement and influence of the foundation deformation on the corridor, and further reducing the settlement of the corridor.

[0052] It should be noted that the elastic coefficient of the pressure spring 406 is relatively large, and it will only be compressed when it is subjected to a large pressure. At the same time, the amount of gas generated by the reaction inside the reaction chamber 402 is also related to the displacement of the piston block 404. The greater the degree of settlement, the greater the displacement of the piston block 404, so that more hydrochloric acid solution is pumped into the reaction chamber 402 for reaction, and the amount of gas generated and the expansion pressure inside the airbag 401 are also greater. The expansion degree and pressure of the airbag 401 are automatically adjusted according to the stress generated by the degree of settlement, ensuring that different degrees of reaction force and filling pressure are applied to different settlements of the pipeline corridor, effectively avoiding deformation of the pipeline corridor, and providing buffer time for manual maintenance.
