Anchoring agent feeding device and using method

Abstract

The invention discloses an anchoring agent feeding device and a using method. The anchoring agent feeding device is applicable to geotechnical engineering, the portion under a coal mine well and tunnel engineering. The device comprises an anchoring agent connector and an anchoring agent injector. The anchoring agent connector is composed of an upper cavity, a lower cavity, a membrane and a centering stabilizing structure; the upper cavity and the lower cavity are of membrane-screen-shaped cylindrical structures, and the diameter of the upper cavity and the lower cavity is matched with that ofanchoring agents; the centering stabilizing structure is of a feather-shaped structure which is fixed to the outer sides of the upper cavity and the lower cavity and diverges outwards, and the diameter of the centering stabilizing structure is matched with that of the anchoring agent injector. The anchoring agent injector is composed of a C-shaped pipe body, an outer thread and an inner thread. The anchoring agent injector is put into an anchor rod cringle, and the multiple anchoring agents are connected through the anchoring agent connector and are fed into the bottom of a mounting hole withthe anchoring agent injector. The device is applicable to installing anchor cables of multiple specifications, and the problems that when the multiple anchoring agents are fed into the mounting hole,the anchoring agents are turned, misaligned or clamped, and the anchoring agents do not coincide with the hole center are solved.

Description

technical field [0001] The invention relates to an anchoring agent sending device and a using method, especially suitable for an anchoring agent sending device and using method for sending anchoring agent into installation holes in geotechnical engineering, coal mine underground and tunnel engineering, and belongs to surrounding rock support protection technology field. Background technique [0002] Bolt support is a reinforcement and support method used in surface engineering such as slopes, deep foundation pits of rock and soil, and underground chambers such as tunnels and stopes. It has the advantages of low cost, good support effect, easy operation, and easy use. It has the advantages of being flexible and occupying less construction headroom. Due to the characteristics of the rock mass at different depths around the roadway and the stress environment in which it is located, the surrounding rock is prone to uncoordinated deformation, so the bolt / cable needs to be pre-ti...

AI Technical Summary

Problems solved by technology

Both of the above two patents provide a device for installing the anchoring agent, but the device provided by the former only solves the problem of difficulty in feeding the anchoring agent. The anchor cable cannot remove the device when stirring the anchoring agent into the bottom of the hole. When the anchoring agent is stirred, it is easy to damage the device, and when the side of the road encounters coal slag in the hole, it is difficult for the device to go deep into the bottom of the hole due to the existence of the iron sheet in the front; Still having trouble getting the anchoring agent to the bottom of the hole
