Embodiment Construction

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] An elastic support type resin anchoring agent anti-fall empennage, comprising an elastic fin 1 and a hollow thin-walled cylinder 2, the inner diameter of the empennage thin-walled cylinder 2 is smaller than the outer diameter of the resin anchoring agent used in conjunction with it, and the outer diameter is smaller than the diameter of the drilled hole, and the elastic fin There are several sheets 1, and they are evenly distributed. One end of the elastic...

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 an elastic supporting type resin anchoring agent anti-fall tail fin and a spraying and anchoring method. The elastic supporting type resin anchoring agent anti-fall tail fin comprises a plurality of elastic fin pieces and a hollow thin-walled cylinder. The inner diameter of the tail fin thin-walled cylinder is smaller than the outer diameter of a resin anchoring agent which is matched with the tail fin thin-walled cylinder for using. The outer diameter of the tail fin thin-walled cylinder is smaller than the hole diameter of a drilled hole. The multiple elastic fin pieces are evenly distributed, one ends of the elastic fin pieces are connected to the hollow thin-walled cylinder, and the other ends of the elastic fin pieces are freely suspended. The elastic fin pieces and the hollow thin-walled cylinder are overall in an inverted-cone shape. In the stretching state, the diameters of incircles of the suspended sections of the elastic fin pieces are larger than the diameter of the drilled hole, and the pointed ends of the elastic fin pieces have sharpness. According to the designed anti-fall tail fin which is simple and is easily mounted on the existing resin anchoring agent, the situation that the anchoring agent is inserted in the drilled hole is not affected, the anchoring agent can also be prevented from falling off from the vertical drilled hole, and in addition, the anti-fall tail fin in a spraying hose can further increase the action area of compressed gas for pushing the anchoring agent in 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 an elastic support 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 a...
