Description

Technical Field

[0001] The present application relates to the field of foundation settlement monitoring technology, and in particular to a foundation settlement monitoring device. Background Art

[0002] Under complex site conditions, foundation reinforcement technology and engineering monitoring and management techniques are employed to optimize the foundation's bearing capacity and minimize settlement and deformation. Dynamic compaction is a foundation treatment method that uses a heavy hammer to impact the foundation with free fall, thereby increasing its bearing capacity and reducing settlement. Post-dynamic compaction foundation settlement monitoring equipment is specialized equipment used to assess and monitor foundation settlement after dynamic compaction treatment.

[0003] Currently, foundation settlement monitoring relies primarily on static levels or optical fibers. Static levels primarily utilize the principle of communicating vessels, measuring the drop in the liquid level when settlement occurs. This requires the coordinated operation of multiple levels. Common fiber-optic measurement methods include short-period fiber Bragg grating (FBG) sensing and distributed fiber-optic sensing, which monitor foundation settlement by varying the optical parameters of the fiber. Both of these solutions are complex to install and expensive. Utility Model Content

[0030] The following is combined with Figure 1-5 This application is described in further detail.

[0031] An embodiment of the present application discloses a foundation settlement monitoring device.

[0032] Reference Figure 1 A foundation settlement monitoring device includes a positioning mechanism 1 and a monitoring mechanism 2.

[0033] Reference Figure 1 and Figure 2 The positioning mechanism 1 includes a mounting tube 11, a positioning rod 12, a laser transmitter 13, and a remote control terminal 14. The mounting tube 11 is partially vertically buried at the location to be monitored, and an insertion port is defined at the top of the mounting tube 11. The positioning rod 12 is vertically inserted into the mounting tube 11 through the insertion port.

[0034] Multiple laser emitters 13 are provided for emitting laser light toward the location of the monitoring mechanism. Each of these laser emitters 13 is mounted on the portion of the positioning rod 12 that is exposed above the ground. These laser emitters 13 are spaced apart and arranged around the central axis of the positioning rod 12. Each of these laser emitters 13 is electrically connected to a remote control terminal 14, which controls the activation and deactivation of the laser emitters 13.

[0035] There are multiple monitoring mechanisms 2 , which are all arranged outside the positioning mechanism 1 and spaced apart around the positioning mechanism 1 . The multiple monitoring mechanisms correspond one to one with the multiple laser emitters 13 .

[0036] Reference Figure 3 and Figure 4 The monitoring mechanism 2 includes a support plate 21, a measuring rod 22 and a sleeve 23. The bottom surface of the support plate 21 is provided with a plurality of plug-in elements with pointed ends. The sleeve 23 is spherically hinged to the upper surface of the support plate 21.

[0037] The lower end of the measuring rod 22 is integrally formed with a hinge ball 221, and the support plate 21 defines a hinge cavity 211 for the hinge ball 221 to articulate. A silicone stopper protrusion 222 is embedded around the periphery of the hinge ball 221, and a stopper groove 212 is defined in the wall of the hinge cavity 211 for the stopper protrusion 222 to insert, ensuring the stability of the ball-shaped hinge connection between the measuring rod 22 and the support plate 21.

[0038] The sleeve 23 has openings at both ends and is sleeved on the circumference of the measuring rod 22 . The circumference of the sleeve 23 is provided with a plurality of scale lines 231 , which are arranged at intervals along the length direction of the sleeve 23 .

[0039] In this embodiment, the sleeve 23 is slidably connected to the measuring rod 22 along its length. The measuring rod 22 is provided with a positioning member 24, which is used to secure the sleeve 23 relative to the measuring rod 22. With this design, after installing the monitoring mechanism 2, the laser emitter 13 is remotely controlled to illuminate the measuring rod 22. The position of the measuring rod 22 is then adjusted so that the laser reaches the zero scale position, facilitating subsequent readings after foundation settlement.

[0040] Specifically, an adjustment cavity 223 is defined within the measuring rod 22, extending along the length of the measuring rod 22. An adjustment rod 225 is disposed within the adjustment cavity 223, one end of the adjustment rod 225 being rotatably connected to the upper end wall of the adjustment cavity 223, and the other end being rotatably connected to the lower end wall of the adjustment cavity 223.

[0041] The top of the measuring rod 22 is rotatably connected to an adjustment knob 224, which is fixedly connected to an adjustment rod 225. A sliding cavity 226 is defined along the circumference of the measuring rod 22 along its length. This cavity 226 extends through the wall of the adjustment cavity 223. A sliding member 232 is fixedly connected to the inner wall of the sleeve 23, extending through the cavity 226 into the adjustment cavity 223.

[0042] Reference Figure 4 and Figure 5 The sliding member 232 is provided with a through hole 233 for the adjustment rod 225 to pass through. The positioning member 24 includes a first threaded portion 241 and a second threaded portion 242. The first threaded portion 241 is disposed on the outer periphery of the adjustment rod 225, and the second threaded portion 242 is disposed on the inner wall of the through hole 233. The first threaded portion 241 and the second threaded portion 242 are threadedly engaged. When adjusting the position of the sleeve 23 relative to the measuring rod 22, the adjustment knob 224 is rotated, which drives the adjustment rod 225 to rotate. During the rotation of the adjustment rod 225, the sliding member 232 is driven up and down, thereby driving the sleeve 23 up and down. The simple structure enables stepless adjustment and is easy to operate.

[0043] In this embodiment, the remote control terminal 14 is disposed on the measuring rod 22 so that the monitoring personnel can perform monitoring work at any time when they arrive at the monitoring location, and the risk of losing the remote control device is also reduced.

[0044] The implementation principle of a foundation settlement monitoring device is as follows: when installing the settlement monitoring device, first install the positioning mechanism 1 at the position to be monitored; then install multiple monitoring mechanisms 2 around the positioning mechanism 1 outside the position to be monitored.

[0045] When installing the monitoring mechanism, first adjust the measuring rod 22 and the sleeve 23 to vertical; then turn on the laser emitter 13 so that the laser reaches the measuring rod 22; then turn the adjustment knob 224 to adjust the position of the sleeve 23 relative to the measuring rod 22 until the laser reaches the zero scale.

[0046] When monitoring the foundation settlement, the laser transmitter 13 is turned on by a remote control device, and the position where the laser hits the sleeve 23 is observed and a reading is taken.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
