复杂地层高压旋喷桩施工质量的控制

Control of Construction Quality of High-pressure Jet Grouting Pile in Complex Strata

高压旋喷桩是一种高效地基处理方法,其利用高压喷射流将水泥浆液注入地下与土体混合固化形成坚固的桩体,该技术广泛应用于基坑支护、地基加固和防渗工程等领域。实施高压旋喷桩施工时,必须根据不同的地质条件调整技术参数和施工措施以保障桩体的质量。阐述了针对复杂地质条件下的高压旋喷桩采用的施工技术及施工质量控制要点。

High-pressure rotary jet grouting technology is an efficient method for foundation treatment.It utilizes high-pressure jet streams to inject cement slurry into the ground,where it mixes and solidifies with the soil to form solid pile bodies.This technology is widely used in various fields such as foundation pit support,foundation reinforcement,and anti-seepage projects.During the implementation of high-pressure rotary jet grouting construction,it is essential to adjust technical parameters and construction measures according to different geological conditions to ensure the quality of the pile bodies.This article mainly discusses the construction technology and key points of quality control for high-pressure rotary jet grouting in complex geological conditions.
