Production:

Self-drilling anchor bolt construction technology is a new anchoring technology. The key to apply this technology is to have construction equipment, such as drilling rigs. At present, the domestic market lacks efficient drilling rigs for self drilling anchor bolt. In this situation, Hengnuo has invested a lot of manpower and financial resources, cooperated with well-known manufacturers in the industry, and developed the first domestic one after more than one hundred application field investigations and tests. The special drilling rig for self drilling anchor bolt makes construction more efficient.

Self drilling anchor system is mainly used for slope engineering, ground and foundation engineering,tunnel and underground engineering. It can be used for pre-construction support and can effectively enhance the stability of soil and rock mass.

Key attributes

Cable bolt is composed of high-strength steel wire,barrel & wedge and plate.

The cable bolt support force is relatively large, and it is anchored by grouting, which is suitable for reinforcement of large-section chambers and roadways in underground coal mines.

Usually, cable bolt needs to be prestressed, it is an active force supporting, and can be used as apermanent anchoring project.

The advantages of cable bolt:

1. cable bolt is made of high-strength steel strands, and its bearing capacity is better than ordinary rock bolt.

2. It can be pre-stressed and actively supported.

3. The anchorage length is better than ordinary rock bolt.

4. plain or bulbs available.
