Large deformation pallet for tunnel surrounding rock deformation monitoring

Abstract

The invention provides a large deformation pallet for tunnel surrounding rock deformation monitoring. The large deformation pallet comprises a pallet box, a spring group and a sliding cover plate. The spring group is arranged in the pallet box, and the spring of the spring gorup are the same. The lower ends of the springs are fixed to the bottom surface of the pallet box. The opening of the pallet box is arranged at a sliding cover plate which can move up and down in the pallet box. The upper ends of the springs are fixedly connected to the sliding cover plate. The side wall of the pallet box is provided with a monitoring port for monitoring the displacement of the sliding cover plate. The middle part of the cover plate is provided with a cover plate positioning hole. The bottom surface middle part of the pallet box is provided with a pallet box positioning hole. A positioning component orderly goes through the cover plate positioning hole and the pallet box positioning hole and is fixed in a tunnel surrounding rock to be monitored. The invention provides the large deformation pallet for tunnel surrounding rock deformation monitoring, the cost is reduced, and tunnel full section deformation can be realized.

Description

technical field [0001] The invention belongs to the field of stress monitoring and support for surrounding rock deformation of large-deformation soft rock roadway, and relates to a large-deformation pallet used for monitoring deformation of surrounding rock of roadway. Background technique [0002] In mining and geotechnical engineering, anchor (cable) support has been widely used as a fast, economical and effective support form, and in the design of anchor (cable) support, the deformation amount and deformation pressure of surrounding rock The monitoring of roadway support is of great value to grasp the effect of roadway support and the working status of support components. In traditional monitoring, the cross point method and the installation of hydraulic pillows are often used to monitor the deformation and force of the surrounding rock of the roadway, which not only increases a large amount of monitoring costs. Moreover, it is difficult to monitor the deformation and pre...
