Abstract

The invention discloses a surrounding rock supporting device. The surrounding rock supporting device comprises a surrounding rock and further comprises a first supporting leg, a second supporting leg,a first fastener and a second fastener, wherein the first supporting leg and the second supporting leg are respectively supported on a first side wall and a second side wall which are oppositely arranged on the surrounding rock in a one-to-one correspondence manner; the first fastener comprises a first buckle groove, a first buckle piece and a second buckle piece, wherein the first buckle piece and the second buckle piece are located on two sides of the first buckle groove and oppositely arranged, the first buckle groove is buckled on the first supporting leg, and the first buckle piece and the second buckle piece are both mounted on the first side wall; and the second fastener comprises a second buckle groove, a third buckle piece and a fourth buckle piece, wherein the third buckle pieceand the fourth buckle piece are located on two sides of the second buckle groove and oppositely arranged, the second buckle groove is buckled on the second supporting leg, and the third buckle pieceand the fourth buckle piece are both mounted on the second side wall. According to the surrounding rock supporting device, the uniformity of supporting effect on the surrounding rock is improved, andthe effect of stabilizing supporting of the surrounding rock is achieved.

Description

technical field [0001] The invention relates to the technical field of roadway or tunnel support, in particular to a surrounding rock support device. Background technique [0002] Metal support technology has been widely used in tunnel support of mine roadways, railways and various underground projects at home and abroad, and it is one of the key technologies essential to achieve safety, high productivity and high efficiency in construction projects. [0003] In the prior art, when the support structure supports the side wall of the surrounding rock, it is generally fixed and installed on the surrounding rock by anchor rods and anchor cables at the initial stage of support, which has the problems of poor support stability and uneven force. The rock is easy to deform under the action of point load or local load, and the anchor rod and anchor cable are also easy to be damaged. [0004] Therefore, it is necessary to solve the above technical problems. Contents of the inventi...
