An integral push-and-pull method for installation of roadway anchor cable anchoring agent

Abstract

The invention discloses an integral push-lead type method for the installation of a tunnel anchor cable anchoring agent. The method comprises the following steps: connecting multiple anchoring agent cartridges filled with the anchoring agent integrally; installing the integrally connected anchoring agent cartridges in a push-lead mechanism; propping an anchor cable against a base plate at the rear end of the push-lead mechanism, and then inserting the push-lead mechanism equipped with the anchoring agent cartridges into a drilled hole formed in rock or coal; pushing the anchor cable toward a drilling direction, so that the push-lead mechanism reaches the top of the drilled hole, using a roof bolter for continuing to push and stir the anchor cable correspondingly, so that the multiple anchoring agent cartridges in the push-lead mechanism are broken, and the anchor cable is anchored in the stable rock or coal by using the anchoring agent. In addition, the invention further provides a device for the method; the device has the advantages of simple structure and good stability, and can effectively solve the problems of multiple-time installation of the anchoring agent cartridges, high probability of blockage of drilled holes, complicated installation process, long support time, high labor intensity of workers and other difficulties restricting the development of the tunnel support technology in the installation process of the existing anchoring agent cartridges.

Description

technical field [0001] The invention belongs to the technical field of coal mine roadway support, in particular to a method for installing anchor cables and anchoring agents in coal mine roadways. Background technique [0002] In recent years, with the continuous expansion of coal mine mining scale, mining intensity and depth, the surrounding rock pressure of the roadway has gradually increased. At present, the use of anchor cable support in mine roadway support has become very common in the field of roadway support. It has played a pivotal role in a series of problems that are not conducive to the control of roadway surrounding rock, such as high ground stress and complex geological conditions in mines. However, during the installation process of the traditional anchoring agent, one or more anchoring agents of the same type or different types need to be placed in a borehole. To the bottom of the borehole, the method of pushing the anchoring agent in stages is often adopted...

Problems solved by technology

[0003] The purpose of the present invention is to solve the above problems, to provide an integral push-and-pull device for the installation of the roadway anchor cable anchoring agent, which has a simple structure and good stability, and can effectively solve the problems existing in the installation process of the existing anchoring agent coil. The anchoring agent roll needs to be installed many times, the borehole is easily blocked during installation, the installation process is cumbersome, the support time is long, and the labor intensity of the workers is high, which restricts the development of roadway support technology; in addition, the present invention also provides a method using The method of the above-mentioned device is characterized in that it includes an integral push-and-pull device for the installation of the anchoring agent for the roadway anchor cable, and the integral push-and-pull device includes a plurality of anchoring agent rolls connected as one and containing the anchoring agent, And the push-and-pull mechanism for installing the integrated anchoring agent medicine roll in it, and the anchor cable for pushing on the chassis at the rear end of the push-and-pull mechanism; the anchor medicine medicine roll is equipped with several sections An anchoring agent medicine roll of a fast resin anchoring agent and an anchoring bag containing a medium-speed resin anchoring agent, the pushing mechanism includes a U-shaped clip for accommodating the plurality of anchoring agent medicine rolls, and the U-shaped clip The inner wall of the clip is provided with a hook connector for hooking the top of the anchoring agent roll, which is used to fix and connect the plurality of anchoring agent rolls with the U-shaped clip, and install it on the U-shaped clip. Chassis at the bottom of the clamp; said chassis is circular, and its edge is provided with a pair of symmetrical lugs, and a round hole is set on each lug, so that the bottoms of the two U-shaped arms of the U-shaped clip are respectively inserted into the In a circular hole, the anchoring agent cartridge containing the anchoring agent is blocked in the clip through the chassis, and the bottom of the chassis is provided with a concave circular hole for placing the anchor cable, and the anchor cable is placed in the concave circular hole Inside, when the anchor cable pushes the chassis, the concave circular hole plays a role in guiding the anchor cable;
