Water Swelling Friction Bolt is made by high strength welded tube folded itself and welded to seal at both end of bolt.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.
