This paper introduces application of taking high-pressure churning pile into closed water curtain design to construction of bridge pier foundation in water of the Jialingjiang Bridge No.1 on the Shitian Highway and its working effect. The water-resistance curtain of churning pile has effectively solved the problem of inflow water in foundation pit, keeping the following work without water inflow. It should have some significance and reference value for water-resistance construction in similar foundation pit.
