Land subsidence monitoring device for tunnel construction and detection method thereof

Abstract

The invention discloses a land subsidence monitoring device for tunnel construction, and relates to the related technical field of land subsidence monitoring. The land subsidence monitoring device comprises a bottom plate and a monitoring box used for detecting land subsidence, sealing shafts are symmetrically and fixedly connected to the two sides of the upper surface of the bottom plate, sliding grooves are symmetrically formed in the two sides of the monitoring box, convex plates are connected to the interiors of the sliding grooves in an attached mode, the side, away from the monitoring box, of each convex plate is fixedly connected with a balance plate. The invention further discloses a detection method of the land subsidence monitoring device for tunnel construction. The detection method comprises the steps of A device positioning, B balance adjustment, C vertical positioning, D stable detection and E water level exploration. The length of a settlement rod is quantitatively adjusted through a telescopic rod, deep underground water in a tunnel can be conveniently detected, the top end of the settlement rod is closed through a sensing module when the telescopic rod is collected, the bottom end of a positioning rod slides in a positioning module through a limiting groove, the bottom end of the positioning rod is limited through a limiting module, and sliding out of the limiting groove in the adjusting process is avoided.

Description

technical field [0001] The invention relates to the related technical field of ground subsidence monitoring, in particular to a ground subsidence monitoring device for tunnel construction and a detection method thereof. Background technique [0002] Land subsidence refers to the phenomenon of ground subsidence, which is a major engineering geological problem in major cities around the world. It generally manifests in two forms: regional subsidence and local subsidence, which can cause buildings to tilt and damage the stability of the foundation. Coastal cities will cause seawater intrusion, which will have a great impact on production and life. There are many reasons for land subsidence, such as crustal movement and sea level rise, which will cause regional subsidence. Groundwater is closely related. [0003] In China's invention patent application number: CN201811005201.5, a device for monitoring karst geological environment is disclosed. Although the device for monitoring...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a ground subsidence monitoring device for tunnel construction and a detection method thereof, which solves the problem that when the ground subsidence is monitored in the tunnel, whether the device is measured or the ground is inclined or vertical is not taken into account, resulting in detection As a result, there is a large error, and the device cannot be folded and folded when it is not in use, resulting in a problem that the device is too large, which is not convenient for transportation and use, and the efficiency is not high in actual use.
