Abstract
The utility model discloses a non-metal grouting anchor cable, which comprises a guide cap, anchor cables, a grouting pipe, slurry outlets, a grouting pipe joint and an anchor cable tail end, wherein three anchor cables are grouped in one bundle and the bundle is arranged in the grouting pipe; a plurality of slurry outlets are formed on the wall of the grouting pipe; the guide cap is arranged at one end of the grouting pipe; the grouting pipe joint is arranged at the other end of the grouting pipe and is connected with the anchor cable tail end; screw threads are arranged on the anchor cable tail end; and the grouting pipe is connected with a grouter pipeline through the screw threads. The non-metal grouting anchor cable is made from high-strength composite material carbon fibre/glass fibre, so sparkles are not generated when a coal mining machine cuts; the non-metal grouting anchor cable is flame retardant and antistatic, is safe and reliable in use, high in tensile strength, higher in breaking force and light in weight, can be bent and coiled, and is convenient to transport; a deep hole of a working face is reinforced and supported under the condition that a coalface cannot be supported by using a metal anchor cable; and grouting operation and supporting operation can be performed by combining a chemical grouting method on a working face site and advanced reinforcement can be performed on upper and lower roadway coal bodies on the working face.
Description
Technical field
The utility model relates to grouting cable anchor under a kind of mine, and coal-face carries out the nonmetal grouting cable anchor of advance support at exploitation process under particularly a kind of soft broken wall rock condition.
Background technology
At present, along with the superficial part coal resources reduce day by day, enter the resource deep mining in succession, because the increase of the coal mining degree of depth and geostatic stress, make increasing coal mine work area be in soft broken country rock state, wall caving, roof fall appear in work plane easily in exploitation process, even cause work plane to stop production, according to statistics, because of causing work plane, working face wall wall caving or roof collapse stop production, its off-time can reach 40%～60% of total off-time, and China has 18% fully-mechanized mining working to be trapped in the low yield state because of the Surrounding Rock Control state is undesirable every year approximately.Current domestic normal employing solves work plane wall caving roof fall problem with chemical grouting in conjunction with the method for metal bolt support in working surface hydraulic support, but this method cost height, control range are little, and when coal-winning machine cutting coal body, can run into anchor metal unavoidably, be easy to produce spark, blast, cause potential safety hazard, in addition, because anchor metal or anchor cable all have higher shear strength, damage coal winning machine cutting bit easily.
Summary of the invention
Technical problem to be solved in the utility model is the drawback that overcomes existing anchor metal, cable bolting, and provide a kind of and can guarantee when coal-winning machine cutting coal body, not produce spark, flame-retardant and anti-static, tensile strength height, in light weight, flexiblely coil, convenient transportation, safe and reliable a kind of grouting cable anchor made from nonmetals.
The technical scheme in the invention for solving the technical problem is: this nonmetal grouting cable anchor includes guiding cap, be characterized in: it also includes anchor cable, Grouting Pipe, slurry outlet, Grouting Pipe joint, anchor cable tail end, anchor cable is formed a branch of being arranged in the Grouting Pipe by three, the Grouting Pipe tube wall is provided with a plurality of slurry outlets, and the evenly distribution that becomes to interlock, Grouting Pipe one end is provided with guiding cap, the other end is provided with the Grouting Pipe joint, the Grouting Pipe joint links to each other with the anchor cable tail end, the anchor cable tail end is provided with screw thread, links to each other with the slurry filling machine pipeline by screw thread.
The utility model solves another technical scheme that its technical problem takes: described grouting cable anchor is made with carbon fibre of composite material/glass fiber.
The utility model solves the another technical scheme that its technical problem takes: described Grouting Pipe is made with aluminium plastic material.
This nonmetal grouting cable anchor provided by the utility model, it is to make with the high strength composite carbon fibers/fiberglass, do not produce spark during the coal-winning machine cutting, fire-retardant, antistatic, safe and reliable, the tensile strength height, be higher than steel, higher Fracture Force is arranged, in light weight, be 1/4th of unidimensional steel weight, bend radius is 1 meter, flexible coiling, convenient transportation, realized that can not use the metal anchor cable to carry out under the situation of supporting work plane being carried out deep hole at coal-face reinforces and supporting, not only can carry out the grouting support operation in conjunction with the chemical grouting method at the work plane scene, and can reinforce in advance the work plane coal body in conjunction with chemical grouting in the lane up and down at work plane.
