An anchoring agent leak-proof orientation method

Abstract

The invention discloses an anti-leakage orientation method for anchoring agents. After anchoring holes are constructed, the anchoring agents are inserted into anchoring agent installation components,the anchoring agent installation components include anchoring agent installation cylinders and anti-leakage blades, the anti-leakage blades are distributed in the outer walls of the anchoring agent installation cylinders, the interiors of the anchoring agent installation cylinders are divided into two upper and lower anchoring agent installation holes by partitioning pieces, and the anchoring agents are inserted into the anchoring agent installation holes; the anchoring agents are installed, an anchor rod is inserted into the lowest anchoring agent installation hole, and the anchor rod and theanchoring agents are integrally pushed to the bottoms of the anchoring holes; the anchor rod is rotated to break the partitioning pieces, so that the anchoring agents are stirred, gaps between the anchor rod (cable) and the inner walls of the anchoring agent installation holes are filled with the broken anchoring agents, an oriented blade can ensure that multi-volume anchoring agents are alignedwith the anchoring holes to prevent the outflow of the anchoring agents in each protection segment, and a relatively closed chamber is formed between the adjacent two anchoring agent installation components, so that the closed chamber is evenly filled with the anchoring agent.

Description

technical field [0001] The invention belongs to the technical field of roadway (tunnel) support, and in particular relates to an anchoring agent leak-proof orientation method. Background technique [0002] Since the 1990s, bolt support technology has been widely used in the field of coal mine roadway support due to its remarkable technical and economic advantages. The anchor net support technology is more and more used in the field of coal mine roadway support in my country because of its low cost and convenient construction. Anchor rod (cable) is the most important supporting material in anchor net support, and its anchoring quality is the key to the success or failure of anchor net support. With the complexity of my country's coal mining conditions and the continuous development of bolt support theory, the strong support technology with high strength, high stiffness and high pre-tightening force has further increased the requirements for the anchorage quality of bolts (ca...

AI Technical Summary

Problems solved by technology

During construction, anchor rods (cables) are usually used to directly push multiple volumes of anchoring agent to the bottom of the hole. Since the anchoring agent is soft, when subjected to a large thrust, the anchoring agents are prone to overlap and even be damaged, especially the top plate. When anchoring, under the action of gravity, the anchoring agent is more likely to flow out, and the anchoring agent is unevenly distributed, so that the effective anchoring length cannot be guaranteed, and eventually the anchoring quality cannot meet the requirements
