Shanxi hollow grouting anchor

Hollow grouting anchor Hao Bo Machinery specializes in the sales, the industry for many years, large-scale, good reputation, is your first choice to buy hollow grouting anchor! Details of consultation 13,165,376,735 hollow grouting anchor primarily used for lower intensity of his early support When the tunnel was found broken wall rock tunnel have case, this hollow grouting anchor to reinforce. Broken fracture the rock faces of the original bond between the cement slurry through integral, more conducive to long-term stability of surrounding rock and permanent support of. First, the main components: mainly consists of hollow grouting anchor anchor soso body, trays, rigging, only the pulp plug member. With most of the country increasing depth of mining, roadway support more and more difficult, the grouting and resin anchor anchor anchor anchor combined, through complementarity between the two, both of the two strengths and overcome their own shortcomings, the formation of a new breed of anchor; by increasing the injection pressure, the slurry in full drilling, achieve full length while drilling spread to the surrounding rock fissures from surrounding rock the adhesive curing effect, achieve deep anchor Note Second, the main features: 1. anchor installation, preload exactly the same way as resin bolt (screwed) to cancel the tensioning process, not only to achieve stirring tension integrated quick installation, but also the anchor and Bolt can be synchronized bearer form an integral supporting role; 2. The cable lock body and structure of the new structure, to ensure the grouting path premise that the cable diameter minimized, the required installation aperture is also much smaller High installation efficiency, realize a small aperture, large tonnage; 3. anchor soso hollow structure for the new body, comes grouting core pipe, grouting using a reverse way, not only eliminates the possibility of air pockets empty, there is no need tied at the scene turns grouting pipe, the exhaust pipe and sealing grouting hole, so that greatly simplify the construction step 4. upper part of the cable is stirred resin drug volume end of the anchor, the lower end of the use of thread lock, immediately after installation can carry it that is the various existing grout bolting products can not be done, and for self-stability of poor roof rock is very beneficial and necessary; 5. With thread lock, working reliable locking mechanism, not will slip, will not produce sparks, the underground moisture, water spray adaptability to the environment is the use of a locking clip Anchorage manner unmatched; 6. With anchoring strength of high-strength steel wire spiral rib PC manufacturing anchor compared with the same diameter of the anchor strand cut cut into more than 15% increase, while anchoring the ductility can be increased by 25%; 7. Because immediately after installation can carry, so grouting can be arranged in a certain distance behind the head a certain range The anchor one end note, it is very convenient construction; threaded locking mechanism centering function, anchor exposed small and uniform length, does not affect the effective height of the roadway. Third, the spiral rib PC wire manufacture of new varieties and specifications hollow grouting anchor anchor anchor type anchor soso strong structure and parameters of the spiral rib steel wire (mm) Cable Diameter (mm) Breaking with the load (tonnes) lock Thread Size Mounting Hole (mm) 9 根 wire + φ10 φ5 grouting surrounding the core tube φ20.6 33 M33 × 2 φ28 8 根 wire + φ10 φ6 grouting surrounding the core tube φ22.6 40 M36 × 2 φ28 ~ φ32 9 根 φ6 perimeter wire + φ12 grouting core tube φ24.6 45 M39 × 2 φ32 ~ φ35 8 根 φ7 surrounding wire + φ12 grouting core tube φ26.9 54 M39 × 2 φ32 ~ φ35 9 根 φ7 + φ14 wire surrounding the core tube grouting φ28.9 60 M42 × 2 φ35 ~ φ42 four applications: 1. replace the current small-diameter cable, coal roadway bolting reinforcement for reinforcement; 2. For full seam top coal caving Roof strengthening support; 3. move ahead for roadway reinforcement Pressure on stage; 4. for large cross section roadway and large span crossing point cut in the support; 5. For high stress in deep mining area large deformation roadway and repair; 6. for coal and other mine soft rock roadway and repair. ? 22 hollow grouting anchor technical parameters (1) wire nominal diameter: 6.0mm (2) Anchor Fast Cable diameter; 22 mm (3) Length:? 8000mm (4) Installation diameter: 32mm (5) and the breaking strength? Force: Strength 1760Mpa, breaking force ≥420KN (6) resin anchor length: 1000 ~ 1500mm (7) hollow grouting tube specifications:? 7.5mm outside diameter of the inner diameter of 10mm (8) injection pressure:? ≥5.0MPa, maximum 7.0MPa Hollow grouting anchor advantages: 1. Hollow grouting anchor grouting own core pipe, grouting direct way, not only eliminates the possibility of voids, but also eliminates the need to install an exhaust pipe, lashing grouting pipe, the exhaust pipe of the process, so that the construction process greatly simplified. 2. Hollow grouting anchor for the stirring resin drug volume top end anchor, immediately after installation can carry. Threaded end of the structure, carried out by tightening the nut, and thread lock does not slip, more reliable. 3. Hollow grouting anchor the required installation aperture is small, resin drug volume by stirring anchor bolt and grouting to achieve one. 4. Hollow grouting anchor exposed length greatly reduced, effectively overcome anchor the exposed part of the roadway occupied by the roadway road repair project costs, and create positive conditions for the long-term safety in production.
