Abstract

A teaching device for observing the separation layer of the roof under the joint support of anchor rods and cables and its use method, mainly including a retractable anchor rod, a base point anchor, a casing, an outer measuring cylinder, an inner measuring cylinder, steel strands, and a retractable anchor cable 1. Rigid plastic formation module; the hard plastic formation modules are connected together by steel strands, and the surface of each hard plastic formation module is coated with standardized formation filling patterns to represent different lithological formations. The modules can move each other to simulate the separation phenomenon. The retractable anchor rod and the retractable anchor cable are installed in the hard plastic formation module. The plastic formation module is connected to the steel frame, and the up and down movement of the hard plastic formation module is controlled by the gear and the steel strand connected by the handle of the long rod, demonstrating the change process of the roof separation layer. The demonstration device has a simple structure and can fully demonstrate the mechanism of the combined support of bolts and cables and the working principle of the roof separation instrument.

Description

technical field [0001] The invention relates to a roof separation layer observation teaching device and a use method thereof, in particular to a roof separation layer observation teaching device and a use method suitable for the combined support of anchor rods and anchor cables. Background technique [0002] In the roadway support in our country, the joint support method of bolt and anchor cable is generally adopted. The function of the bolt is to support and reinforce the shallow surrounding rock around the roadway in time to improve the overall bearing capacity and self-stability of the surrounding rock. By applying a pre-tightening force to the anchor cable, the support strength of the bolt support can be further improved, and the deformation and damage of the surrounding rock can be controlled; when the damage range of the surrounding rock exceeds the anchorage length of the anchor rod, the anchor cable can The suspension function suspends the loose rock of the roof in t...
