Abstract

The invention relates to an underground roadway convergence and deformation continuous monitoring device. A plurality of self-customized cross sections are arranged in an underground roadway to be used as monitoring surfaces; each monitoring surface is provided with a convergence and deformation monitoring device; each convergence and deformation monitoring device is used for transmitting a signal to a general control circuit board by a data line; the general control circuit board is connected with an industrial control computer; the structure of each convergence and deformation monitoring device is that a displacement sensing device is arranged at the upper part of each of arc feet on the two sides of each monitoring surface; three fixed points are arranged on the same monitoring surface; the fixed points and the displacement sensing devices are crossly distributed; each fixed point is provided with a pull wire sleeve to be connected with the adjacent displacement sensing device. The monitoring device can realize real-time and automatic continuous measurement and has high precision; a monitoring process has no interferences on normal operation of tunnels or roadways.

Description

technical field

[0001] The invention relates to a continuous monitoring device for convergence deformation of an underground tunnel, belonging to the technical field of tunnel and tunnel engineering. Background technique

[0002] Using a convergent meter to monitor the convergence deformation of the cross-section of the roadway is an important means to test the stability of the top of the underground roadway project. , especially under the condition of frequent disturbance of underground excavation activities, it has become an important means to test the effect of engineering design and ensure the safe construction and operation of the project.

[0003] At present, the commonly used tunnel or roadway deformation monitoring technologies mainly include automatic tracking total station, automatic close-range photography technology and convergence meter. The automatic tracking total station has high measurement accuracy and can be observed under the unique weak light conditions...
