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 umbrella-shaped resin anchoring agent anti-fall type spraying device and a spraying and anchoring method. An umbrella-shaped resin anchoring agent anti-fall tail fin comprises a hollow thin-walled cylinder and an umbrella-shaped apron with holes. The inner diameter of the hollow thin-walled cylinder is smaller than the outer diameter of a resin anchoring agent which is matched with the hollow thin-walled cylinder for using. The outer diameter of the hollow thin-walled cylinder is smaller than the hole diameter of a to-be-drilled hole. The umbrella-shaped apron is arranged on the circumferential side of the hollow thin-walled cylinder; the thickness of the umbrella-shaped apron is gradually changed from top to bottom, the closer to the hollow thin-walled cylinder the umbrella-shaped apron is, the larger the wall thickness is, andthe closer to the outer edge the umbrella-shaped apron is, the smaller the wall thickness is; when the umbrella-shaped apron is in the stretching state, the diameter of the lowest edge is larger thanthat of the drilled hole; and the multiple ventilation holes are uniformly formed in the umbrella surface of the umbrella-shaped apron. According to the anti-fall tail fin which is simple and is easily mounted on an 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 fromthe 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 umbrella-shaped resin anchoring agent anti-drop spraying device and a spraying 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.
