Abstract

The invention discloses a rock tunnel surrounding rock pressure gauge fixing device. The rock tunnel surrounding rock pressure gauge fixing device comprises a base plate and a steel arch, wherein a pressure gauge is fixed to the base plate through fastening screws, the base plate is fixed to the steel arch through positioning screws, and a plurality of adjustment bolts used for adjusting the inclination angel of the pressure gauge are arranged between the base plate and the steel arch, so that the pressure gauge can be closely attached to a surrounding rock excavation face. The rock tunnel surrounding rock pressure gauge fixing device is simple in structure and convenient to operate, the angle of the pressure gauge and the angle of excavated surrounding rock can be adjusted effectively through the adjustment bolts, the spatial posture of the pressure gauge can be adjusted flexibly due to the fact that both the adopted fastening screws and the adopted positioning screws are elastic, and the fixing strength of the pressure gauge is improved effectively due to the fact that the base plate is fixed to the steel arch.

Description

technical field [0001] The invention relates to a fixing device, in particular to a fixing device for a surrounding rock pressure gauge of a rock mass tunnel. Background technique [0002] Surrounding rock pressure monitoring is an important test content in underground engineering construction. The usual practice is to bury pressure gauges in the surrounding rock for monitoring, but it is very difficult to install and fix the pressure gauge in the rock mass tunnel, and the pressure gauge cannot be directly installed on the surface of the surrounding rock. At the same time, the installation of the pressure gauge does have some special requirements, such as the front of the pressure gauge should be as parallel as possible to the excavation surface of the surrounding rock. Therefore, it is very necessary to design a fixing device for the surrounding rock pressure gauge of the rock mass tunnel to obtain the real pressure of the surrounding rock of the rock mass tunnel. Conten...
