Displacement type soil layering settlement deformation monitoring system

Abstract

The invention discloses a horizontal type bidirectional deformation monitoring system. According to the system, a large casing pipe and a small casing pipe are matched and connected with each other for forming a sleeve group; multiple sleeve groups are in connection end to end; the large casing pipe is provided with a large casing pipe chute; one end of the small casing pipe is in slip connection with the large casing pipe in the same sleeve group by being positioned by the large casing pipe chute, and is provided with line distribution disks, and each line distribution disk is provided with multiple line-distribution-disk line distribution holes; the other end of the small casing pipe is fixedly connected with the large casing pipe of a subsequent sleeve group via a connection ring; line bodies and the line distribution disks are in one-to-one correspondence, and the end of each line body is fixedly connected with the line-distribution-disk line distribution hole of the corresponding line distribution disk; and other line bodies penetrates the other line-distribution-disk line distribution holes of the line distribution disk. The beneficial effects comprise that the system is capable of monitoring the settlement or rebounding deformation statuses at different height in soil, has a wide range, realizes displacement type measurement because soil deformation can be reflected to the end via the line bodies, and satisfies wide-range monitoring demand.

Description

technical field [0001] The invention relates to an automatic measuring device capable of monitoring layered settlement and deformation of soil, in particular to a displacement monitoring system for layered settlement and deformation of soil. Background technique [0002] Expansive soil or other soil slope engineering usually undergoes deformation such as horizontal relaxation and settlement under the action of internal load during the construction period and operation period, which has a great impact on the safety and stability of the slope engineering. Therefore, it is of great significance to monitor the deformation of slope soil. At present, the horizontal displacement monitoring method of the soil mainly adopts the deep displacement of the inclinometer pipe and the displacement of the surface observation pier, and the vertical displacement monitoring method of the soil mainly adopts the methods of settlement ring and surface benchmarking point. At home and abroad, there...

Problems solved by technology

At home and abroad, there are no special instruments and automatic instruments for simultaneously monitoring the horizontal relaxation deformation and settlement deformation at different horizontal positions of the soil slope, and there is no monitoring equipment that meets the large deformation inside the soil.

The existing measurement methods are almost all manual measurement, the measurement workload is heavy, it is difficult to realize real-time monitoring, and the monitoring effect has a lag
