Lock bolt connection reinforcing device and linkage fixing method for preventing rock collapse

摘要

The present invention relates to a rock bolt connection reinforcing apparatus and a linkage fixing method for preventing collapse of rock walls, rock masses, and the like due to various impacts and weather effects from its side when constructing an inclined zone or tunnel adjacent to a road .;The rock bolt connection reinforcing apparatus for preventing rock collapse of a rock bolt according to the present invention comprises: a rock bolt fixedly installed at a predetermined interval on a rock wall; A support plate having a central portion formed with a hole through which the protruded portion of the rock bolt penetrates and having a surface facing a surface of the rock wall; A plurality of wires positioned so as to intersect with each other in a curved shape with reference to the respective rock bolts and having mutually adjacent supporting plates to have a force opposing the rock wall and rock mass; A fixing groove for fixing the bent state of the wire is formed at one side edge portion of the container shape covering the portion where the wires intersect with each other and a hole through which the end portion of the locking bolt can penetrate is formed at the center portion of the other side A wire fastener formed; And a nut fastened to the lock bolt such that the wire fastener is pressed against the support plate.;Therefore, according to the present invention, when the force is increased by the collapse of any one of the rock bolts provided on the rock, the wires supported by the neighboring rock bolts are connected to each other to provide a supporting force,
