Tube slotted bolt) tube seam-anchor is a full length novel active strengthening the surrounding rock bolt, it is three-dimensional part of a longitudinal slit high strength steel pipe, when installed in slightly smaller than the diameter drilling in the entire length of the hole wall exert radial pressure and prevent the friction of surrounding rock downturn, plus pallet load bearing capacity of the bolt tray, so that the surrounding rock in a three-way by state and achieve the rock stratum great. In the case of blasting vibration surrounding rock anchor shift late anchoring force has significantly increased, when the surrounding rock occurrence of significant displacement, the anchor does not lose its support resistance, it has better features than the rose shell-anchor . Specializing in the production of tailor-made: FRP Bolt, exploring water drill pipe, braided resin anchor, hollow grouting anchor rebar resin bolt, L-bolt, right-handed bolt, seam pipe anchor, B19 anchor, B22 wind drill pipe, drill rod, the hexagonal hollow bolt, gas emission drill pipe, braided (resin) bolt, to help anchor the drill pipe, coal drill, the anchor rope drill pipe, the bolt drill pipe, down-the-hole drill pipe seam pipe anchor performance and specifications, the initial anchoring force of the slotted tube bolt main technical performance (1): 3 to 7 tons; (2) tube ring pull-off load: 8 to 10 tons; (3) anchor tube tensile breaking capacity: 12 to 13 tons; (4) corrosion resistance than the A3 steel high 20 to 30%, is conducive to long-term use.
