Depending on the different geological conditions of the construction site, excavating foundation pits also has different conditions and safety standards, especially when working in deep foundation pits, these conditions and safety standards are more stringent. Detecting the settlement and deformation of foundation pits is an important measure to prevent safety hazards during foundation pit operations.

[0003] A Chinese patent document with authorization announcement number CN220356357U discloses a foundation pit settlement detection device, which uses a suspension rope to drive a squirrel-cage drum to move up and down in the foundation pit to be detected, and then by observing the position changes of the pendant set in the squirrel-cage drum, the staff can judge in real time whether the foundation pit has settled, and know the relative amount of settlement.

The staff needs to approach the squirrel-cage drum and measure the position change of the pendant in order to know the accurate settlement of the foundation pit. For this reason, a foundation pit settlement detection device is proposed. Utility Model Content

[0034] The detection component 2 includes a guide member that can limit the movable range of some parts of the winding component 3, a clamping member that can display the vertical settlement of the tested foundation pit in real time, a moving member that can display the horizontal deformation amplitude of the tested foundation pit in real time, and a collection member that can feed back the settlement deformation data of the tested foundation pit to the control panel 105 in real time. The guide member includes a guide frame 201 fixedly connected to the body 1, a first support 202 is fixedly installed in the guide frame 201, a first reversing wheel 203 is movably installed in the first support 202, the clamping member includes a support rod 204 fixedly connected to the guide frame 201, a slider 205 is movably connected to the outer side of the support rod 204, and the slider 205 A first spring 206 is provided on one side, an electric push rod 207 is fixedly connected to the slider 205, a clamping block 208 is fixedly connected to the telescopic end of the electric push rod 207, the moving part includes a second support 209 fixedly connected to the guide frame 201, a rotating shaft 210 is movably connected between the second supports 209, a limiting groove 211 is integrally formed on the outer side of the rotating shaft 210, a second reversing wheel 212 is movably connected to the outer side of the rotating shaft 210, and a second spring 213 is provided at the front and rear of the second reversing wheel 212.

[0036] The guide frame 201 drives the various components installed therein to move in the device. The first reversing wheel 203 installed in the guide frame 201 through the first support 202 can cooperate with the second reversing wheel 212 to limit the movable range of the cable 302 in the guide frame 201, so that the portion of the cable 302 located between the first reversing wheel 203 and the second reversing wheel 212 can only move in a direction perpendicular to the clamping block 208.

[0037] In this embodiment:

[0038] The winding assembly 3 includes a winding machine 301 fixedly installed in the frame 101, and a cable 302 is arranged between the winding machine 301, the first reversing wheel 203, the clamping block 208, and the second reversing wheel 212. One end of the cable 302 is fixedly connected to a magnetic block 303, and a positioning plate 304 is fixedly connected to the lower part of the magnetic block 303; the magnetic block 303 is magnetically connected to the positioning plate 304; the winding machine 301 can control the position of the magnetic block 303 in the device or in the foundation pit by retracting and releasing the cable 302, and contact the foundation pit through the positioning plate 304.

[0039] Working principle:

[0040] When the device is installed and used for foundation pit settlement detection, the device is moved to the vicinity of the foundation pit, and the side of the device where the control panel 105 is installed is kept away from the foundation pit. Then, according to the position of the predetermined detection point in the foundation pit, the positioning plate 304 is suspended at the position through the joint work of the first hydraulic rod 102, the second hydraulic rod 103, and the winder 301. After the suspension is completed, the cable 302 should be ensured to be tight as a whole;

[0041] Then, the electric push rod 207 can be used to close the two clamping blocks 208 and clamp the cable 302. After the clamping is completed, the winder 301 is made to release a small section of the cable 302 so that the cable 302 between the winder 301 and the clamping block 208 is no longer tight.

[0042] When the foundation pit is deformed by settlement, the positioning plate 304 is always close to the foundation pit under the action of gravity. Therefore, the positioning plate 304 whose position has changed will pull the cable 302 through the magnetic block 303, and transmit its own vertical displacement to the clamping block 208, so that the clamping block 208 moves laterally in the guide frame 201, and transmit its own horizontal displacement to the second reversing wheel 212, so that the second reversing wheel 212 moves longitudinally on the rotating shaft 210.

[0043] During this process, the staff can know whether the foundation pit has settled and deformed through the position changes of the clamping block 208 and the second reversing wheel 212, and accurately know the degree and direction of the settlement and deformation of the foundation pit based on the data displayed on the control panel 105 and the position changes of the positioning plate 304 before and after the detection.

[0044] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
