25/5 hollow bolt tunnel grouting anchor bolt grouting anchor, hollow bolt, hollow bolt, hollow grouting anchor grouting hollow bolt grouting hollow bolt by bolt to remove the self-drilling drill evolved into the function, the whole thread hollow bolt body, together with the anchor head, plate, nut, only the pulp plugs and other components. Each of its parts are in order to ensure maximum grouting mortar when filling full, dense and mortar can penetrate into the surrounding rock fissures at up to tens of kilograms of pressure, and can be easily mounted plate and nut. Bolt Body: Length of continuous waveform threaded surface, easy to cut and take a long bolt, an increase compared to the smooth rod rod grouting material itself bonding area, thereby improving the anchoring force; hollow design, hollow rod directly As the high pressure drilling and grouting channel channel feng shui, compared with a solid rod, obtained by grouting better stiffness and shear strength. Pulp tampon: the rubber material, combined with the 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. Anchor head: with steel anchor head, not only to fixed and centering anchor rod and can produce a certain anchoring force in the rock bolting and grouting. Features 1. hollow bolt grouting hollow design, the bolt to achieve a grouting pipe function, avoiding the traditional construction process when mortar grouting pipe pulled out due to the loss. 2. full grouting, grouting pressure can achieve, improve project quality. 3. Due to the role of the parts, the center is very good rod, mortar anchor body can be full-length wrap to avoid the risk of corrosion, and achieve long-term support purposes. 4. Easy installation, no on-site processing thread, you can easily install plate and nut. 5. The combination of supporting special injection pump and bolt grouting process, is the only complete solution to the traditional problems of supporting anchor anchorage system. Hollow grouting anchor Scope 1, radial reinforcement: hollow bolt instead of the traditional mortar anchor for radial reinforcement construction technology can solve the traditional mortar anchor grouting process is not full, and many can not achieve pressure grouting defects, ensure project quality. 2, the slope reinforcement: hollow bolt reinforced slope instability, not only the process is simple, low cost, and convenient construction, the effect is significant. 3, excavation: excavation of the building reinforced hollow bolt, only a simple process, but also to achieve pressure grouting, improved pit rock conditions. Grouting hollow bolt technology is mainly used in the geological conditions of the surrounding rock moderately good support system. 1) Drilling: Drilling and ordinary rock drill hole cleaning. 2) Insert the bolt: the installed anchor head hollow grouting anchor insertion holes. 3) Install slurry stopper, plate and nut: rock conditions according to the exhaust pipe installation. 4) Connect grouting machine: The end of the bolt and grouting will connect the selected grouting. 5) Grouting: Grouting start the machine, such as the need for improved pressure grouting surrounding rock structure, the need to be raised to the design pressure gauge pointer can.
