Now understand the principles supporting bolt, then let us introduce installation works under the bolt. Bolt installation ① check: Before installing the bolt, to check the direction of drilling, position, angle, depth, anchoring agent, anchor meets the design requirements, if a failure, it can not be installed. ② anchor head Mixing: After eye bolt kick timely installation requires a minimum operated by two people. When installing anchors, the first connector is screwed onto the threaded bolt tail, with the other rod to the bottom of the hole will be anchoring agent pier real, then the placement of coal drill or blender, start mixing, stirring anchor time of 30 to 40 seconds. Stir resin to force uniform, not too much. Take coal bolt torque when drilling 8x multiplier, will hold the rod, after removing temporarily with small pieces of wood or small stones placed in the wells choked rod to prevent the rod decline. ③ pallet install: After the resin solidified, and then remove the connector, immediately install pallet, gaskets, when install pallet, the pallet to be lifted by one person hold the anchor set into another person quickly put on pads, tighten the nut on the double, the higher the roadway when another person needs to withstand the pallet with a long bar to prevent fall injuries. Requires close pallet wall, double cap single pad tighten security or anti prohibited pallets padded coal blocks. Finally, with a torque wrench to tighten the nut bolt torque multiplier double that of prestressed anchoring force of up to 90%. Turn from the outside and inside, playing a note one, will support all the empty top finish. Bolt must be tightened with a torque wrench tight mechanical or ensure close pallet wall. Bolt preload torque wrench is the main product of Warner Mechanical and Electrical Equipment Co., Ltd. Tai'an City, the following is a brief introduction: "Warner" brand voice alarm bolt torque wrench, extension socket head, adjustable wrench, bolt preload force detector for shotcrete tunnel roadway predetermined torque fastening bolt nut bolt torque multiplier official website, and as a bolt tension detection tool. Separation and collapse accident occurred bolt torque multiplier prices in shotcrete tunnel, mostly due to the installation of the anchor bolt anchor nut after tightening the fastening indicators did not meet the requirements due; fastening Luo cap fastening degree is the key to the bolt to play a full role in the key, one of the important tools MC3 bolt preload torque wrench is to complete this work of. MC3 bolt preload torque wrench technical parameters: Torque Detection range: 60-300N.m ,100-500N m; 280-760 Nm; 200-1000 Nm; 700-2000 Nm; 1500-3000N.m; 2500. -4000N.m Warner electromechanical JN13-24/35 type bolt torque multiplier provided by Warner electromechanical manufacturing.
