Roadway deformation monitoring device

Abstract

The invention relates to the technical field of engineering monitoring and discloses a roadway deformation monitoring device comprising a top plate and a bottom plate; the top plate and the bottom plate are respectively fixed at the top and the bottom of the roadway through a rooting rod with a rooting point, the roadway deformation monitoring device is firm in fixation and not easy to shift and damage, the effectiveness and accuracy of measured data are guaranteed, moreover, a distance measuring device is fixed at a top measuring point on the top plate through the free end of a graduated scale and is not easy to damage, during measurement, the measuring device is pulled to a bottom measuring point of the bottom plate through a pull ring, the distance between the top measuring point and the bottom measuring point is measured so as to monitor relative displacement of the top and the bottom of the roadway, whether the roadway is deformed or not can be accurately and effectively judged, and the operation is simple. In addition, the monitoring device is fixed on the top plate, after the measurement is finished, the pull ring is loosened, and the distance measuring device is reset to the top measuring point of the top plate through rollback of the graduated scale, such that the normal function of the roadway are not influenced, and whether the roadway is deformed or not can be conveniently judged through measurement.

Description

technical field [0001] The invention relates to the technical field of engineering monitoring, in particular to a roadway deformation monitoring device. Background technique [0002] The convergence of the roadway surrounding rock is the most basic data to confirm the stability of the surrounding rock, judge the support effect, guide the construction sequence, prevent the collapse of the vault, and ensure the construction quality and safety; the peripheral displacement is the change of the stress state of the roadway surrounding rock and the occurrence The most direct reflection of rheological deformation. By monitoring the dynamic changes of the surrounding rock and support structure at each construction stage, grasp the safety state of the structure during the construction process, judge the stability of the surrounding rock and the reliability of the support, and ensure construction safety and long-term stability of the structure. Therefore, for coal mines, all mining ro...

Problems solved by technology

On-site measurement methods generally use tower rulers or steel tapes to measure. During the measurement process, it is often difficult to find the floor measurement points because the roadway floor has been cleaned or leveled, or the floor measurement points have been displaced or damaged, which affects the measurement. In addition, when using a steel tape to measure, it is often not easy to root the end of the steel tape on the top plate measurement point, and the operation is more troublesome

[0005] In addition, a certain measuring device will be fixed on the roof on site to facilitate the use of each measurement. However, for coal mine roadways, most of them have the function of rail auxiliary transportation. During the transportation process, mine vehicles are prone to damage the measuring device.
