Tel: 155-8971-5136.QQ: 877995102 main components: a hollow grouting anchor consists of anchor soso body, trays, rigging, only the pulp plug components. 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 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 anchor 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, installation high efficiency, 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 in the field tied turns grouting pipe, the exhaust pipe and sealing grouting hole, so that the construction step greatly simplifies the upper part of the cable 4. stirred resin drug volume end anchor, threaded locking the lower end, can carry immediately after installation, it is Grouting anchor various existing products can not be done, and for self-stability of poor roof rock is very beneficial and necessary; 5. using thread locking mode, the lock mechanism and reliable work, not slip does 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 anchor prestressed high strength steel wire spiral rib than the same strand cross-sectional diameter of the anchor 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 at a certain distance from the head behind a range of anchor Note the cable once finished, so the construction is very convenient; threaded locking mechanism centering function, anchor exposed small and uniform length, does not affect the effective height of the roadway.
