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.
