Abstract

The invention discloses a ground surface monitoring site suitable for loess geological tunnels, a setting device of the ground surface monitoring site, and a working method of the setting device. The setting device realizes the effective setting of the monitoring site in the soil; after being buried, the monitoring site is filled with concrete, so that the concrete is conveniently fixed and molded; the setting device meets the burying specification of the ground surface monitoring site for the tunnels, and enables the shape and size of the concrete to meet the requirements of the specification; a tapered drill bit is adopted at the bottom end, so that the monitoring site can be conveniently rammed into the soil, so that the working efficiency of ground surface monitoring site setting is increased. The ground surface monitoring site is characterized by comprising a buried rod; the bottom end of the buried rod is connected with the tapered drill; the buried rod is fixedly connected with a concrete filled tank, an opening is formed in the middle of the concrete filled tank, and the buried rod passes through the opening; a cross wire is arranged at the top end of the buried rod.

Description

technical field [0001] The invention relates to the technical field of tunnel monitoring point layout, in particular to a surface monitoring point and a layout device and method suitable for loess geological tunnels. Background technique [0002] There are more and more tunnel projects in the west of my country, and the west of China is a mountainous area with more loess geological tunnels. Various types of instruments and tools need to be used in tunnel construction to measure and observe the mechanical behavior of surrounding rock, support and lining, as well as the mechanical relationship between them, and evaluate their stability. [0003] The monitoring and measurement contents of the tunnel mainly include: surface settlement, vault sinking and peripheral convergence. Through monitoring and measurement, understand the dynamic changes of strata and support structures at each construction stage, judge the stability of surrounding rock, the reliability of support and lini...
