Problems solved by technology

[0002] The monitoring instrument is a device that can detect the horizontal displacement of the excavated soil layer in a deep foundation pit in real time. The problem in the existing technology is that the monitoring instrument needs to be supported and fixed by the support column during monitoring, but the support column and the monitoring The monitor does not have a good fixing method, so the monitor is usually connected to the support column with a buckle, but the monitor is easily removed and installed for a long time, and the buckle will break and the monitor will not be fixed stably. Shaking affects the monitoring results

Embodiment 1

[0026] Such as Figure 1 to Figure 3 As shown, the dynamic horizontal resistance displacement monitoring equipment based on the deep excavation soil layer provided by the embodiment of the present invention includes a monitor 1, a support column 2 and a fixed block 3, the fixed block 3 is located at the bottom of the monitor 1, and the fixed block 3. The inner cavity at the bottom is in contact with the top of the support column 2. The inner cavity of the fixed block 3 is provided with a storage slot 4. The inner cavity of the storage slot 4 is provided with a positioning mechanism 5 used in conjunction with the monitor 1. The inner cavity of the storage slot 4 A transmission mechanism 6 used in conjunction with the positioning mechanism 5 is provided.

[0027] refer to figure 2 , the positioning mechanism 5 includes two positioning rods 501, the front side of the positioning rod 501 is fixedly connected with an extrusion block 502, the bottoms of the two positioning rods 50...

Embodiment 2

[0038] The method of using the dynamic horizontal resistance displacement monitoring equipment based on deep foundation pit excavation soil layer described in embodiment 1:

[0039] When in use, press the transmission rod 602, the transmission rod 602 will drive the two extrusion blocks 502 to move through the movable plate 601 and stretch the tension spring 603, and the extrusion block 502 will drive the two positioning rods 501 to move when moving , the positioning rod 501 will compress the spring 505 through the slider 503 during the moving process, after the positioning rod 501 moves to a proper position, release the transmission rod 602, the tension of the tension spring 603 will shrink and the movable plate 601 will be reset , during the reset process of the movable plate 601, the elastic force of the spring 505 rebounds, and the sliding block 503 will drive the positioning rod 501 to insert into the inner cavity of the positioning groove 9 and fix the fixed block 3 throu...
