32 self drilling anchor bolt slope Supplying professional manufacturer of hollow bolt - Luoyang JiangTai Ltd. - Production of self-drilling anchors, quality, affordable, welcome new and old customers to consult, since anchor rod, self-drilling anchors, grouting anchor, self-drilling anchors pit slope supporting self-feeding type anchor bolt self-feeding type anchor bolt from the full thread hollow body, alloy drill, connected sets, plate, nut, only the pulp plugs and other components. Bolt Body: Length of continuous waveform threaded surface, easy to install alloy drill, connected sets, nut, and can be cut and connected longer. Alloy drill: wear resistant steel casting, with a strong penetration, so that the bolt can pass through all kinds of rocks, and set out the pulp holes. Pulp tampon: combining pressure grouting, a certain seal, easy to increase the fullness and density of the grouting. Plate: hot rolled forming gaskets, easy dense paste the rock surface, and withstand greater stress in the surrounding rock. Nuts: The Dome or hexagonal nut, can be transferred to the surrounding rock stress concentration plate. Features self-feeding type anchor bolt factory production of self-drilling thick-walled seamless material that good, perfect and fast surface craft and workmanship thread forming accessories, truly self drilling anchor drilling, grouting, unified anchoring and other functions. 1) before the bolt has penetrating power drill, in the role of general drilling machines can easily penetrate all types of rocks. 2) Bolt has a continuous thread of international standard waveforms, can be completed as a drill with drill holes drilled into the anchor. 3) As the body without having to pull the drill bolt, which can be used as grouting empty channel, grouting from the inside to the outside. 4) efficient pulp can only plug so that the grouting grouting pressure to maintain a strong, fully fill the gap, fixed broken rock, high strength plate, nuts can be delivered to the deep rock stress evenly on the peripheral wall of the surrounding rock reach surrounding rock and bolt supporting each other purposes. 5) the use of mechanical power cut processing technology, high strength link sets, so self-drilling anchors while drilling has extended features, it can be applied to relatively small construction space, to achieve a specialty of rock bolt reinforcement design ideas . 6) As the anchor of the Trinity features make it in the construction of various types of rock conditions, no casing Wall, pre-grouting and other special techniques can also be formed to ensure the anchor and anchor holes and grouting effect. Self-feeding type anchor scope is mainly used in crushing rock, soft and weak rock, highland stress deformation, weathered rock, sand stone hole collapse folder severe or difficult to support the complex geological anchor hole. In the tunnel advance support, radial support and various high slope remediation project can be a good improvement of surrounding rock support, support to achieve the desired effect. Self-feeding type bolt construction craft 1. Drilling: The trolley or jackhammer drill bolt will be installed to the design depth of drilling (For a longer bolt, connected sets available to connect, and then drilling rig) . 2. Remove the drill, install only the pulp plug, install it in the anchor hole at 25cm away from the orifice, such as the special circumstances surrounding rock grouting pressure is too large or broken, can also be used with the sealing of Anchorage. 3. Install equipped with a plate and nuts; 4. grouting: grouting joints by quickly selected the anchor end of the injection pump and connected to the machine and start grouting. Is filled with a slurry wall rock fissures to improve the surrounding rock structure, while a slurry wrap anchor rod body to effectively prevent corrosion. Grouting pressure should be based on design parameters and determine the performance of injection pump, water-cement ratio reference values: 0.45: 1 to 0.5: 1, gray sand than the reference value: 1: 0 to 1: 1.
