Equal High Tensile Strength Grouting Anchor Bolts With Better Support Efficiency

Underground Works Grouting Anchor Bolts High Ground Stress Easy Installation

Introduction of self-driling grouting bolts:

It is very common for underground works to encounter soft surrounding rock, fractured zone and great deformation due to high ground stress. It is difficult for anchor work, especially under the condition that serious hole collapsing occures and extra-long bolt is needed, while it is impossible to solve the problem with ordinary bolt. This self-drilling bolt embodies drilling, grouting and anchoring as a whole and can improve the condition of surrounding rock in course of deformation due to high ground stress.

Function of each parts of self-driling grouting bolts:

1. spherical nut

To transmit the stress of surrounding rock to the palte

2. Anchoring plate

To bear higher stress of urrounding rock

3. Grout stopper

To keep grouting at certain pressure to fully fill the clearance of surrounding rock

4. Anchor body

It has the international standard wave-shape connecting thread and is very easy to be installed with bit, coupling and fasten nut. It can also be cut or connected very freely.

5. Coupling

It can realize the purpose of elongating to the designed depth while drilling

6. Bit

It has strong ability of penetrating, so the anchor can pass through various rock with it
