Description
Technical field
The utility model relates to a kind of reinforcing anchor cable, particularly relates to a kind of gob side entry driving fender reinforcing grouting cable anchor.
Background technology
Gob side entry driving generally has Tunnelling Along Goaf and stays establishes fender gob side entry driving two kinds, relative to Tunnelling Along Goaf, stays and establishes fender gob side entry driving to have very large superiority.When implementing fender gob side entry driving, fender cranny development under the effect of overlying rock is strengthened even broken, and easily cause coal column deformation instability, impact is produced normally.Various types of bolt support is tested when the supporting of gob side entry driving fender in many mining areas, but gob side entry driving fender is the process adapting to gob side entry driving, gob side entry driving fender body adopts coal to make, more broken, intensity is low, and self-bearing ability is limited, cannot provide stable origin of force for anchor pole, supporting effect is not good, and common cable bolting also exists identical defect.
Utility model content
The purpose of this utility model is to provide a kind of gob side entry driving fender reinforcing grouting cable anchor, and it is two-way to wearing reinforcing that this grouting cable anchor can not only realize gob side entry driving fender, but also improves bulk strength and the supporting capacity of coal column by slip casting.
To achieve these goals, the technical solution of employing is the utility model:
A kind of gob side entry driving fender stays establishes grouting cable anchor, comprise anchor cable, fastener, stop grouting plug and Anchor Agent, the coal column established is stayed to be connected in described anchor cable and mine gob side entry driving, boring is had in described coal column, anchor cable is arranged in boring, stop grouting plug and Anchor Agent are enclosed within anchor cable, fastener is connected to anchor cable two ends and is connected with the two ends adaptation of coal column, described anchor cable comprises front anchor cable body, sleeve and rear anchor cable body, front anchor cable body is by anchor cable body after sleeve connection, the outer wall of described sleeve has injected hole, rigidity Grouting Pipe is all provided with in front anchor cable body and rear anchor cable body.
Preferably, described fastener is set to two groups, and described fastener comprises pallet and lockset, and pallet is fixed tightly in anchor cable one end by lockset, and described pallet connects with coal column side end face.
Preferably, described front anchor cable body and rear anchor cable body are the body of rod of the hollow screw of steel strands wound, and described rigidity Grouting Pipe is arranged in the body of rod.
Preferably, described injected hole is set to multiple, and multiple injected hole is between front anchor cable body and rear anchor cable body on sleeve outer wall.
The beneficial effects of the utility model are:
Anchor cable structure of the present utility model can make full use of the high-tensile characteristic of anchor cable steel strand, and the coal column realized having two scope of freedoms is reinforced.Two-way more scientific to wearing reinforcing anchor cable force structure, inner tension, outer end pressurized during anchor cable reinforcing coal column, and coal column structure two sides simultaneously pressurized when using two-ended cables to reinforce coal column, two surface pressures pass to coal column by force transferring structure again, both played and controlled coal column malformation, played again the effect improving coal column structural stability.The utility model is the hollow grouting cable anchor carrying slip casting core pipe, and sleeve is provided with penetrates slurry hole, implements slip casting, can improve the mechanical property of coal column structure, improve the bulk strength of coal column, increase the supporting capacity of coal column self to the coal column of fragmentation.The slurries of slip casting crack, isolated air can prevent weathering in shutoff coal column, avoid pillar strength significantly to reduce because of the impact of water and air.Slip casting can make anchor cable realize full length fastening, thus improves anchored force and the reliability of anchor cable, is thus conducive to ensureing the stable of coal column.
