Hollow grouting anchor for medium-geological conditions, permanent support and advance support. Bolt through the hollow rod on the pressure grouting, consolidation can be achieved broken rock, cut off groundwater and rod preservative purposes, the rapid formation of supporting force, controlling the stability of surrounding rock. Hollow grouting anchor from the alloy rod, grouting stopper, plate, nut and anchor head components.
1 hollow design, implementation of grouting function.
2 full grouting pressure grouting can realize.
3 pole body centered good, mortar anchor body length can be wrapped to avoid the possibility of corrosion, to achieve the purpose of long-term support.
4 Easy installation, no on-site processing thread, you can easily install plate and nut.
5 using up exhaust anchor head, above the horizon completely solved the problem of hollow grouting anchor exhaust. Hollow grouting anchor for railways, highways, tunnels, mines, water conservancy, slope, dams, bridge foundation, Jianghai lake river, building high-rise building foundation and reinforcement works.
Hollow design, implement the grouting tube function, avoid the mortar loss when the traditional grouting tube pulled out. 2. Grouting full, and can achieve the pressure grouting to improve project quality. 3. Center is good, mortar can wrap the bolt body together, so that it can avoid corrosion to achieve a long-term supporting purposes. 4. Easy installation, without on-site processing of threads, it can be easily installed an plate, nut.
It is mainly applied in complex layer formation of broken rock, loose soil, weathering rock and so on which is difficult to make the hole. It is good for supporting and improving surrounding rock, and can achieve good supporting effect in tunnel support, radial support and various types of slope treatment projects.
