Bolting principle: can be divided into centralized (ends) and a total length of anchor bolt anchor so that the former is tensioned by tightening the anchor head and the other end portion of the fundus end inhibition surrounding rock deformation and loose. Can be divided into wedge joints anchor, expansion shell anchor, resin bolt prestressed cable. The latter is a rod with a hole through the wall of the cementing material, so that the entire length of the bolt in the rock and rock bonded together to produce anchoring effect. Including mortar anchor, resin bolt. Its way into mechanical anchoring anchor type (by friction from Anchorage) and bonded anchor (anchor role played by adhesion). Bolting principles: (1) strengthening arch (squeeze arch) by the action of the bolt so that the surrounding rock formation having a certain thickness to maintain its stability and preventing its external reinforcement arch rock loose to keep the surrounding rock stable. (2) the role of the bear hanging off the soft rock or wall rock suspended in the deep rock solid stability, by bolt to bear the weight of these rock. (3) organizations beams in layered rock bolt action through the layers of rock to form a whole, increase its carrying capacity. On this basis, in order to prevent loose rocks and weathering sprayable 5-20CM mortar or concrete is shotcrete support. High strength bolt cutter is open-ended Warner Tai'an City Mechanical and Electrical Equipment Co., Ltd. Main Products. Split Bolt cutter with hydraulic technology cold cut anchor, multifunction shear head respectively with manual pump hydraulic and pneumatic bolt tension meter common use, and smooth and reliable, powerful, fast, lightweight, operate and easy to carry, suitable for multi-faceted, face a variety of environments, greatly improved work efficiency, reduce labor intensity bolt tension meter offer is ideal for prestressing construction equipment, welcomed by underground workers. Use one of the openings anchor shears to do a visual inspection to see if there is light moving each part, damage and other anomalies, confirming each section can be carried out during normal operation. 2, open the hose type oil pump bolt shears and connect with a fast interface. 3, when the anchor job openings shearing machine operation by one person, one person operation to cut off oil pump provides hydraulic oil. 4, if the opening anchor shears work yet oil-filled cylinder should first make a few full load reciprocating cutter stroke, so that all the working cylinder exhaust air and filled with hydraulic oil, then cut off the device to load the work Mine bolt tension meter, and you should be careful to check whether two parallel edges. 5, the opening anchor bolt shears off when purchasing bolt tension meter, the operator should put a hand cutter flat hand grip bolt, bolt off to prevent pop wounding. Opening anchor off the main technical parameters Rated pressure: 63MPa; cutting force: 300KN; adapt Specifications: ￠ 24mm; fuel storage: ≤0.6L; work force: ≤0.50KN ;.
