D-handed bolt anchor bolt factory price handed right-handed bolt Model

D-handed bolt anchor bolt manufacturers handed right-handed bolt model price to buy a good product, not less coal in Shandong, Shandong coal to provide you with the best quality products, the most attentive service, a comparison and see Look, products or fancy coal! Right-handed bolt, bolt mine handed, right-handed bolt manufacturers, L bolt, right-handed bolting, mine right-handed bolt, bolt a building, right-handed bolt Description: D-anchor threaded rod, also known as other strong anchor, anchoring force measurement is a tool, with a small size, light weight, easy to carry, easy to operate, and security features, widely used in a variety of trenches coal, defense, and transportation tunnels operations. Second, the right-handed right-handed bolt anchor introduces no longitudinal ribs rebar type resin bolt (the left-handed bolt) perform MT146.2-2002 standard. It is a special processing technology made bolt thread segment strength strength greater than the rod body, threaded section bending shear good performance, roadway support new high-strength bolts. The bolt high strength, reasonable structure, preload force, able to automatically adjust the direction of the force, increase of binding rock, can be mechanized fast installation. may end anchors, anchor and lengthen the whole anchor, is mainly used for large deformation of mine roadway Heights pressure high intensity support, but also can be used for high railway, hydropower and other projects strength, permanent roadway Third, the technical characteristics of D-1 and other strong anchor bolt thread Pullout test: test construction quality bolt, one anchor pullout method for the determination. 2. reinforcement length: height by hanging along the direction of the unstable rock bolt or surrounding rock load height, but also loose circle thickness testing techniques such as acoustic measurement method used to determine. 3. The composite beam (arch) effect: such a strong thread bolt inserted into the formation a certain depth, squeezing in between each other under formation anchoring force, frictional resistance between layers increases, greatly reduce stress and deflection, equivalent to the number of layers superimposed simple beam (arch) becomes composite beams (arch). Composite beams (arch) flexural stiffness and strength greatly improved, thus increasing the carrying capacity of the formation. Bolt anchoring force provided by the greater role of the more obvious. 4. Using upward exhaust anchor head, completely solve the horizon problem over the hollow bolt grouting exhaust. 5. The center of the rod is good, the mortar can be a total length of anchor body wrap, to avoid the possibility of corrosion, to achieve the purpose of long-term support. Fourth, the advantage of the right-handed bolt: 1 ratio with the specifications of the anti-twist bolt increase the carrying capacity of forty percent. 2 expands the scope of the bolt can achieve short anchors, anchor and lengthen the whole anchor. 3 simple, inexpensive, widely used in coal mines, railways, utilities and other projects of various types of roadway. Five right-handed bolt Usage: 1. Determine the design requirements according to bolt holes with a drilling rig 2. pressure wind net hole 3. The anchor of rock powder into the hole at the end, with the anchor. Stirring rods withstand (mixing time prescribed by anchoring agent models), mixing is completed, remove the blender with, after reaching the waiting time, remove the stir connector, mounted on the anchor plate, ball washers, friction washer, and with a special wrench Tighten the nuts.
