Abstract

The invention provides a self-locking type roadway and side slope supporting device and a supporting method. The self-locking type roadway and side slope supporting device comprises a conical head threaded rod body, a tray and a nut. The top of the conical head threaded rod body is in a small cone shape, and the outer side of the rod body is in a threaded shape; a mounting hole is formed in the middle of the tray, the diameter of the mounting hole is slightly greater than that of the outside thread of the rod body; the inner side of the nut is provided with an internal thread and is fixedly connected with the conical head threaded rod body. And the rod body can realize full-length anchoring and can be recycled.

Description

technical field [0001] The invention belongs to the technical field of roadway and side slope support, and more specifically relates to a self-locking roadway and side slope support device and method. Background technique [0002] Bolt support refers to a reinforcement and support method used in surface engineering such as slopes and deep foundation pits, as well as underground chambers such as tunnels and stopes. The rod body is made of metal parts, wood parts, polymer parts or other materials, and is driven into the pre-drilled holes in the surface rock mass or the rock mass around the chamber. At present, the anchoring section of the anchor rod is mainly anchored by resin anchoring agent, and the The rock is combined with the stable rock mass to produce suspension effects, composite beam effects, and reinforcement effects to achieve the purpose of support. [0003] Based on the above, the inventors found that the existing bolt support has a short anchoring section (only ...
