A tubular glue storage device for anchor rods

Abstract

The invention relates to a tubular glue storage device of an anchor rod, which belongs to the field of underground hard rock and wall rock tubular anchor rod end devices. The tubular glue storage device of the anchor rod comprises a front end of the anchor rod, an unsealed glue storage device, a tubular anchor rod, an anchor rod main body material, anchor rod cross-section hollow part, a manufactured press machine, a press machine groove, a front end part of the glue storage device, an area formed after the glue storage device is sealed, an inner diameter of the anchor rod, a cross-section diameter of the glue storage device, a length of the glue storage device and a surface of the glue storage device, wherein the glue storage device and the front end of the tubular anchor rod have the same shape, the glue storage device is bonded on the front end of the tubular anchor rod using a resin-mixed material before the glue storage device is sealed, and a radial width is avoided from increasing through a corresponding manner when the glue storage device is sealed so as to ensure that the width is less than a drilling hole diameter. The tubular glue storage device of the anchor rod provided by the invention solves the problems in a current method of bonding and fixing an anchor rod by resin that the resin material cannot be mixed uniformly easily at the position of the anchor rod, or the anchor rod cannot be placed into a drilling hole because the width of one end of the anchor rod exceeds the diameter of the drilling hole.

Description

technical field [0001] The invention relates to a tubular glue storage device for anchor rods, which belongs to the field of end devices of tubular anchor rods in underground hard rock surrounding rock. Background technique [0002] There are many bolt support methods in underground hard rock support. For important underground metal mine support, the usual practice is to drill a larger borehole first, and then put the bolt into the hole. In order to improve the anchoring strength, the full-section grouting of the anchor is usually used; the project with a relatively stable overlying rock mass usually adopts the method of tubular anchor anchoring, which can achieve the purpose of saving steel. The section grouting reaches the anchorage strength. [0003] Using synthetic resin cementing anchorage, the general practice is to put the capsule containing cementing resin into the drilled hole. When the bolt is inserted into the borehole, the resin capsule is punctured and the res...

AI Technical Summary

Problems solved by technology

[0006] The present invention mainly solves the problem that in the existing method of using resin cementation to fix the anchor rod, the resin material is not easy to mix evenly at the anchor rod position, or the end of the anchor rod is wider than the diameter of the drilled hole, so that the anchor rod cannot be inserted into the drilled hole , to provide a tubular rubber storage device for anchor rods, the rubber storage device is installed at the front end of the anchor rod, and the front end of the rubber storage device is closed to seal the resin mixed material inside
