Advantages:
This bolt is full length anchoring bolt,advanced technology, it can improve the mechanical properties of the bolt, simplify the installation process and improve the anchoring quality.

Especially in the roadway development engineering of geological surrounding rock with strong blasting vibration and high ground pressure and large deformation, it can control the deformation of surrounding rock more effectively and maintain the stability of roadway space.

It is easy to operate, fast to install (no more than ten seconds for installing one bolt), cheap price and pollution-free to the environment. It is an ideal bolt.


Bearing principle:

When the bolt is expanded by water injection, 15MPa high-pressure water acts on the rock hole through the pipe wall, causing the rock mass to deform, and the metal pipe wall will produce plastic deformation, embedded in the rock mass. The hydraulic expansion bolt will bear the load immediately after installation, and the bearing capacity is large.


Introduction to construction

1. According to the design requirements, determine the anchor hole position and drill hole with drilling machine.

2. Use compressed air to blow out the rock powder in the hole. Put the anchor bolt body on the anchor plate and put them into the hole.
 3. Put the injector on the bolt nozzle. Inject 15 ~ 20Pa high-pressure water into the bolt to swell the bolt.
