Water Swelling Friction Bolt is made by high strength welded tube folded itself and welded to seal at both end of bolt.
Working principle:
When the bolt is used in the hole, the bush with a hole is connected with a chuck of a high-pressure water pump. Start the pump and inject the water into tube, the folded wall of bolt is forced to expand. When the pump reaches a standard pressure, the wall of bolt holds onto the strata and creates a big friction strength to support.Thus, a safety and stable support system is formed.
Advantages of Water Swelling Friction Bolt:
1. Simple installation, saving labor cost.
2. Be used in wide variety of ground conditons.
3. With high supporting strength.
