The present invention provides a collision self-flowing cemented locking device for the anchoring end of a bolt, comprising: a collision device and a screw barrel part, the collision device includes an outer cylinder part and an inner cylinder part, and one end of the outer cylinder part is set in the inner cylinder The outside and the other end of the barrel part are connected with the screw barrel part, and a cavity that can accommodate the anchoring agent is formed between the outer cylindrical part and the inner cylindrical part, and the two can move relative to each other. The outer cylindrical part and the inner cylindrical part There are several through holes on the side walls of the parts. After the outer cylindrical part moves to the left or right relative to the inner cylindrical part, the through holes on the outer cylindrical part and the inner cylindrical part are connected one by one and can be used for anchoring. The channel through which the agent flows out; the present invention proposes a collision self-flowing cemented locking device for the anchoring end of the anchor rod and its use method. The anchoring agent is stored at the front end of the anchor rod. When the anchor rod is inserted into a predetermined position, the tail end of the anchor rod is knocked The anchoring agent will be squeezed and jetted out, so as to achieve the anchoring effect of the anchor rod.
Description
technical field [0001] The invention relates to the technical field of civil engineering, in particular to a collision self-flow cementing and locking device for the anchoring end of a bolt, and simultaneously provides a method for using the collision self-flowing cementing and locking device for the anchoring end of a bolt. Background technique [0002] With the continuous development of civil engineering, infrastructure construction is no longer limited to the ground and low-level, but tends to be more underground, deep-sea, and high-level. The more complex engineering geological environment has higher and higher requirements for the development of geotechnical engineering, especially It is the geotechnical support to ensure the safety and stability of the project. [0003] Bolt support is widely used in geotechnical engineering support, while traditional anchoring mostly uses manual grouting, or uses mechanical expansion to increase the friction between the bolt and the s...
