In order to meet the need of engineering construction, the domestic sand pile ship experienced two generations of development from introduction and imitation to independent research and development. The new sand pile ships can carry out compaction sand pile foundation treatment 66 m under water to improve the production process, the pile diameter can reach 2 m and the replacement ratio of composite foundation can be up to 70%. Due to its better operability, efficiency and environmental protection, the equipment is successfully applied to the construction of Yangshan deepwater port and Hongkong-Zhuhai-Macao Bridge island&tunnel project and the effect is good.
