A kind of anti-drop empennage of plastic blocking type resin anchoring agent and injection anchoring method

Abstract

The invention belongs to the field of anchor rod and anchor cable support in the mining industry or the traffic tunnel industry and particularly relates to a plasticity clamping-type resin anchoring agent fall-prevention tail fin and a spraying and anchoring method. The plasticity clamping-type resin anchoring agent fall-prevention tail fin comprises plasticity fin pieces, a thin neck and a thin-walled cylinder; a resin anchoring agent is arranged in the thin-walled cylinder; the thin neck is arranged at the bottom of the thin-walled cylinder; the diameter of the thin neck is smaller than thatof the thin-walled cylinder, and one end of the thin-walled cylinder is sealed through the thin neck; the multiple plasticity fin pieces are uniformly distributed in the radial direction of the thinneck in an extending mode; one ends of the plasticity fin pieces are connected to the thin neck, and the other ends of the plasticity fin pieces are freely suspended; and in the stretching state, thediameter of an incircle of the suspended section of each plasticity fin piece is larger than that of a drilled hole. The simple fall-prevention tail fin easily mounted on the existing resin anchoringagent is designed, the situation that the anchoring agent is inserted in the drilled hole is not affected, the anchoring agent can also be prevented from falling from the vertical drilled hole, and inaddition, in a spraying hose, the fall-prevention tail fin can also increase the acting area, pushing the anchoring agent, of compressed gas during spraying.

Description

technical field [0001] The invention belongs to the field of bolt and cable support in the mining industry or the traffic tunnel industry, and in particular relates to a plastic jam type resin anchoring agent anti-fall tail and a spray anchoring method. Background technique [0002] During the construction of underground mines or traffic tunnel roadways, the anchoring operation process is as follows: firstly, drill holes that meet the length and diameter at the top of the roadway; secondly, the construction personnel push one or several resin anchoring agents into the boreholes with one hand, and the other Hold the tail of the anchoring agent with the anchor rod in one hand to prevent it from falling; then, the construction personnel slowly push the resin anchoring agent into the drilling hole with the anchor rod to a suitable depth; use a mixer to stir the resin anchoring agent evenly; wait for a certain period of time , upper tray and fastening nuts. [0003] There are fo...

AI Technical Summary

Problems solved by technology

[0007] 4) The existing resin anchoring agent is difficult to be used in the fully automatic anchoring operation process without manual intervention (the anchoring agent will fall from the drill hole without manual intervention)
