Application:
1. It adapts to several projects, such as mine, hydro-junction, slope, bridge base, river bank, high-rise building, construction reinforcement and so on.
2. The management of geological disaster, such as: ground subsidence, collapse, landslide and so on.
3. The reinforcement of coal mine, metallurgy and war industry projects.
Feature:
1. The size of drill bit can control drill hole’s size. Generally, the size of drill hole is about twice or three times as bolt’s diameter.
2. It is convenient for construction in narrow conditions.
3. Mortar can pack the whole bolt, it has good anti-corrosion.
4. Drilling, grouting and anchoring can be finished at the same time.
