Under water bored pile is widely used in levee underwater engineering. Because of the characteristics of the construction hidden, complex process, prone to reinforcement cage floating, hole col apse and other accidents in construction, engineering quality and progress, bring economic loss and the potential safety hazard. Through engineering example to sum up the experience of Jiangdong dyke section of the 3 contract, this paper introduces the underwater cast-in-place pile constr-uction technology and requirements, to guide the future engi-neering practice.
