Development of Pile-Extractor Machine of Water Jet


Article Preview

A Pile-Extractor machine was developed based on the theory of water jet,which was applied in small gravel,sand and soft soil.It consists of four parts:Pile-Extractor component,water-supply system,suspender structure and crane.The experimental results show that it took fifteen minutes all so to extract one precast concrete pipe pile of 15 meters long and 0.5m in diameter.
