Abstract

This utility model discloses a soil settlement monitoring device for geotechnical engineering construction, belonging to the field of geotechnical engineering technology. It aims to solve the problem that traditional soil settlement monitoring devices tilt as the soil settles, leading to inaccurate detection results, continuous data deviation, and masking the true settlement risk. The device includes a frame assembly, a leveling assembly, a detection assembly, and an alarm assembly. This utility model designs a leveling assembly where a connecting cover is connected to a ball sleeve via a universal joint, allowing 360° rotation and suspended at the bottom of the ball sleeve. A cross-shaped counterweight is located at the bottom of the connecting cover. When the soil tilts, the counterweight remains vertical due to gravity, automatically leveling the detection box. When the tilt sensor detects a tilt angle > 0.5°, the damper control mechanism releases hydraulic oil to fine-tune the counterweight position, ultimately achieving a leveling error ≤ 0.1°, thus improving the accuracy of data detection.

Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering technology, and more specifically, to a monitoring device for soil settlement during geotechnical engineering construction. Background Technology

[0002] The foundation will settle under the load of the building. If the foundation settlement, especially differential settlement, exceeds the allowable range of the building, it will affect the normal use of the building at best, and cause cracks and tilting of the building, roadbed subsidence, collapse of dams and other serious problems at worst. In order to understand the settlement of the foundation under the load of the building and the trend of settlement change in a timely manner, so as to take effective measures in advance to prevent accidents, many projects need to set up settlement monitoring.

[0003] Existing soil settlement monitoring devices for geotechnical engineering construction tend to tilt as the soil settles during use, leading to inaccurate test results and continuous data deviations that may mask the true settlement risk. To address these issues, we propose a soil settlement monitoring device for geotechnical engineering construction. Utility Model Content

This solves the problem that traditional soil settlement monitoring devices tilt as the soil settles, which leads to inaccurate detection results, continuous data deviation, and masking of the true settlement risk.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a monitoring device for soil settlement in geotechnical engineering construction, comprising a frame assembly, a leveling assembly, a detection assembly, and an alarm assembly. The leveling assembly includes a curved frame disposed on top of the frame assembly, a ball sleeve disposed at the bottom of the curved frame, a universal joint disposed within the inner cavity of the ball sleeve, a connecting cover disposed at the bottom of the universal joint, hydraulic dampers disposed at the four corners of the bottom of the connecting cover, a counterweight disposed at the bottom of the hydraulic damper, an inclination sensor disposed at the bottom of the counterweight, and a damper control mechanism disposed at the bottom of the connecting cover and connected to the inclination sensor and the hydraulic damper. The detection assembly is disposed at the bottom of the leveling assembly, and the alarm assembly is disposed on one side of the bottom of the detection assembly.

[0006] The counterweight is arranged in a cross shape, and its four corners are connected to the bottom of the hydraulic damper. When the tilt sensor detects that the tilt angle of the counterweight is greater than 0.5°, the damper control mechanism releases hydraulic oil to fine-tune the position of the counterweight, and the final leveling error is ≤0.1°.

[0007] Preferably, the detection assembly includes a detection box disposed at the bottom of the connecting cover, a controller disposed on the front surface of the detection box, a sleeve disposed at the bottom of the controller, a drill rod disposed in the inner cavity of the sleeve, and a pre-embedded part disposed at the bottom of the drill rod. The detection box is equipped with an independent power supply. The detection box is provided with heat dissipation windows on both sides, and the inner cavity of the heat dissipation windows is provided with a dustproof net. The front surface of the controller is provided with a display unit.

[0008] Preferably, the alarm assembly includes a connecting plate with a surface of the drill rod, a displacement sensor on the top of the connecting plate near the sleeve, an upper electrode on the bottom of the connecting rod away from the sleeve, a connecting frame on the side of the detection box near the connecting plate, a lower electrode at the bottom of the connecting frame, and an alarm on one side of the connecting frame, wherein the alarm is electrically connected to the upper electrode and the lower electrode.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model designs a leveling component located between the detection component and the frame component. The connecting cover is connected to the ball sleeve via a universal joint, allowing 360° rotation and suspended at the bottom of the ball sleeve. A cross-shaped counterweight is located at the bottom of the connecting cover. When the soil layer tilts, the counterweight remains vertical due to gravity, automatically leveling the detection box. Simultaneously, the four corners of the counterweight are connected to the bottom four corners of the connecting cover via hydraulic dampers. In conjunction with an inclination sensor, the tilt angle of the counterweight is detected. When the inclination sensor detects a tilt angle > 0.5°, the damper control mechanism releases hydraulic oil to fine-tune the counterweight position. Ultimately, the leveling error is ≤ 0.1°, ensuring the counterweight remains vertical and improving the accuracy of data detection.

[0013] 2. This utility model also incorporates a detection component and an alarm component. An embedded part is placed in the soil layer to be detected. When the soil settles, the embedded part moves downwards, causing the drill rod to move downwards. A displacement sensor detects the displacement distance of the drill rod, thus obtaining specific settlement data. As settlement continues, the embedded part continues to move the drill rod downwards, which in turn moves the connecting plate and the upper electrode downwards until the upper electrode contacts the lower electrode, reaching the maximum settlement threshold. At this point, the upper and lower electrodes are connected, forming a complete current path, and the alarm sounds a settlement alarm, further improving safety. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] This utility model relates to a soil settlement monitoring device for geotechnical engineering construction, comprising a frame assembly 1, a leveling assembly 2, a detection assembly 3, and an alarm assembly 4. The leveling assembly 2 includes a curved frame 201 fixedly connected to the top of the frame assembly 1, a ball sleeve 202 fixedly connected to the bottom of the curved frame 201, a universal ball joint 203 rotatably connected to the inner cavity of the ball sleeve 202, a connecting cover 204 fixedly connected to the bottom of the universal ball joint 203, hydraulic dampers 205 fixedly connected to the four corners of the bottom of the connecting cover 204, a counterweight 206 installed at the bottom of the hydraulic damper 205, an inclination sensor 207 installed at the bottom of the counterweight 206, and an alarm sensor 207 installed on the connecting cover. The damper control mechanism 208, located at the bottom of 204 and connected to the tilt sensor 207 and hydraulic damper 205, includes a curved frame 201 supporting a ball sleeve 202. The ball sleeve 202 is used to connect a universal ball joint 203 for 360° rotation without dead angles. The universal ball joint 203 rotates with the connecting cover 204, which seals the detection box 301 and also supports the hydraulic damper 205. The hydraulic damper 205 connects to the counterweight 206 and adjusts the cleaning angle of the counterweight 206 to keep it vertical. The tilt sensor 207 detects the tilt of the counterweight 206. The damper control mechanism 208 controls the hydraulic damper 205 to release hydraulic oil to fine-tune the counterweight position. The detection component 3 is installed at the bottom of the leveling component 2, and the alarm component 4 is installed on one side of the bottom of the detection component 3. The counterweight 206 is arranged in a cross shape, with its four corners connected to the bottom of the hydraulic damper 205. When the tilt sensor 207 detects a tilt angle > 0.5° in the counterweight 206, the damper control mechanism 208 releases hydraulic oil to fine-tune the counterweight position, ultimately achieving a leveling error ≤ 0.1°. This invention designs the leveling component 2, which is located between the detection component 3 and the frame component 1, and connects to the cover 20. 4. The ball joint 203 connects to the ball sleeve 202, allowing 360° rotation. It is suspended at the bottom of the ball sleeve 202. At the same time, a cross-shaped counterweight 206 is set at the bottom of the connecting cover 204. When the soil layer tilts, the counterweight 206 remains vertical due to gravity, which drives the detection box 301 to automatically level. Meanwhile, the four corners of the counterweight 206 are connected to the bottom four corners of the connecting cover 204 through hydraulic dampers 205. The tilt angle of the counterweight 206 is detected by the tilt sensor 207. When the tilt sensor 207 detects that the tilt angle of the counterweight 206 is >0.5°, the damper control mechanism 208 releases hydraulic oil to fine-tune the position of the counterweight. Finally, the leveling error is ≤0.A 1° angle ensures that the counterweight 206 remains vertical, improving the accuracy of data detection. This invention also incorporates a detection component 3 and an alarm component 4. An embedded part 305 is placed in the soil layer to be detected. When soil settlement occurs, the embedded part 305 moves downwards, causing the drill rod 304 to move downwards. The displacement sensor 402 detects the displacement distance of the drill rod 304, providing specific settlement data. As settlement continues, the embedded part 305 continues to move the drill rod 304 downwards, further moving the connecting plate 401 and the upper electrode 403 downwards until the upper electrode 403 contacts the lower electrode 405, reaching the maximum settlement threshold. At this point, the upper electrode 403 and lower electrode 405 are connected, forming a complete current path, and the alarm 406 sounds a settlement alarm, further enhancing safety.

[0022] Specifically, the detection component 3 includes a detection box 301 snapped onto the bottom of the connecting cover 204, a controller 302 fixedly connected to the front surface of the detection box 301, a sleeve 303 fixedly connected to the bottom of the controller 302, a drill rod 304 inserted into the inner cavity of the sleeve 303, and an embedded part 305 fixedly connected to the bottom of the drill rod 304. The detection box 301 is equipped with an independent power supply. The detection box 301 has heat dissipation windows on both sides, and the inner cavity of the heat dissipation windows is equipped with a dustproof net. The front surface of the controller 302 is equipped with a display unit. Furthermore, the control box is used to carry electronic components such as the controller 302. The controller 302 is used to receive circuit signals from the displacement sensor 402. The sleeve 303 is used to carry the drill rod 304, and the drill rod 304 is used to slide up and down along the sleeve 303. The embedded part 305 is used to connect to the soil layer to be detected. The independent power supply is used to provide power for detection. The heat dissipation windows and dustproof net are used for heat dissipation and moisture prevention. The display unit is used to display settlement data.

[0023] Specifically, the alarm component 4 includes a connecting plate 401 on the surface of the rod 304, a displacement sensor 402 mounted on the top of the connecting plate 401 near the sleeve 303, an upper electrode 403 mounted on the bottom of the connecting rod away from the sleeve 303, a connecting frame 404 mounted on the side of the detection box 301 near the connecting plate 401, a lower electrode 405 mounted on the bottom of the connecting frame 404, and an alarm 406 mounted on one side of the connecting frame 404. The alarm 406 is electrically connected to the upper electrode 403 and the lower electrode 405. Furthermore, the connecting plate 401 is used to support the displacement sensor 402 and the upper electrode 403, and the connecting plate 401 is used to drive the displacement sensor 402 to move. The displacement sensor 402 is used to monitor settlement data. The upper electrode 403 and the lower electrode 405 are connected to form a passage. The connecting frame 404 is C-shaped and is used to support the lower electrode 405 and the alarm 406. The alarm 406 is used to sound an alarm when the settlement reaches a threshold.

[0024] It is worth mentioning that the counterweight 206 is made of high-density alloy, which increases its weight. The weight of the counterweight 206 is twice the weight of the detection box 301, which ensures that the detection box 301 moves with the counterweight 206. The inner wall of the sleeve 303 is provided with a guide groove, and the outer wall of the drill rod 304 is equipped with a guide block that cooperates with the guide groove, which can guide the movement trajectory of the drill rod 304. The surface of the embedded part 305 is frosted, which can increase the friction with the contact surface with the soil layer.

[0025] It is worth noting that the rack assembly 1 includes a base, fixing screw holes at the four corners of the top of the base, a fixing sleeve fixedly connected to the top of the base, a reinforcing rib installed on the edge of the fixing sleeve, and a column inserted into the inner cavity of the fixing sleeve. The top of the column is connected to one end of the curved frame 201. The rack assembly 1 is used to facilitate the installation of equipment.

[0026] Working Principle: This embodiment provides a soil settlement monitoring device for geotechnical engineering construction. In use, the frame assembly 1 is first installed at the location to be tested using fixing bolts. Then, the embedded part 305 is buried in the soil layer to be tested. The leveling assembly 2 is located between the detection assembly 3 and the frame assembly 1. The connecting cover 204 is connected to the ball sleeve 202 via a universal ball joint 203, allowing 360° rotation and suspended at the bottom of the ball sleeve 202. Simultaneously, a cross-shaped counterweight 206 is provided at the bottom of the connecting cover 204. When the soil layer tilts, the counterweight 206 remains vertical due to gravity, automatically leveling the detection box 301. The four corners of the counterweight 206 are connected to the bottom four corners of the connecting cover 204 via hydraulic dampers 205, working in conjunction with the tilt sensor 207 to detect the tilt angle of the counterweight 206. When the tilt sensor 207 detects a tilt angle of the counterweight 206 > 0.5°... The damper control mechanism 208 releases hydraulic oil to fine-tune the counterweight position, ultimately achieving a leveling error ≤0.1°, ensuring the counterweight block 206 remains vertical, thus improving data detection accuracy. The embedded part 305 is placed in the soil layer to be tested. When soil settlement occurs, the embedded part 305 moves downwards, causing the drill rod 304 to move downwards. The displacement sensor 402 detects the displacement distance of the drill rod 304, providing specific settlement data. As settlement continues, the embedded part 305 continues to move the drill rod 304 downwards, further moving the connecting plate 401 and the upper electrode 403 downwards until the upper electrode 403 contacts the lower electrode 405, reaching the maximum settlement threshold. At this point, the upper electrode 403 and lower electrode 405 are connected, forming a complete current path, and the alarm 406 issues a settlement alarm, further enhancing safety.
