Taking the engineering practice of the hydraulic revetment reinforcement by high-pressure rotary jet grouting pile of the western government wharf in Shenzhen port as a study case, this paper introduces the application of triple-tube high-pressure rotary-jet pile for the reinforcement of the hydraulic revetment. Through the description of the reinforcement of high-pressure rotary-jet grouting pile layout, the determination of construction parameters, the construction technology, quality control, and pile foundation detection, this paper verifies the feasibility of the high-pressure rotary-jet grouting pile in the reinforcement of the hydraulic revetment, indicating that the revetment structure protection with high-pressure jet grouting pile is technically feasible and economically reasonable, so it provides a reference for the promotion of the application of jet grouting piles.
