高压旋喷桩在流砂地质基础中的应用分析

Application Analysis of High Pressure Jetting Pile in Quicksand Geology

为了提高流砂地质管道敷设质量,文中探讨了高压旋喷桩在流砂地质实用性,基于实际工程,采用桩基检测和管道CCTV检测方法对桩体改善地基承载力的效果进行分析。结果表明:高压旋喷桩对流砂地质进行加固,不仅改善了流砂地质性能,改善了施工过程中的施工条件,同时预防了管道出现结构性缺陷,保证了管道敷设质量的可靠性。

In order to improve the laying quality of quicksand and quicksand geological pipelines, this paper discusses the practicability of high-pressure rotary jetting piles in quicksand geology. Based on the municipal rain and sewage diversion reconstruction project, the pile foundation detection and pipeline CCTV detection methods are used to analyze the effect of the pile body on improving the bearing capacity of the foundation. The results show that the reinforcement of the quicksand geology by the high-pressure jetting piles not only improves the quicksand geological properties, but also improves the construction conditions during the construction process, and at the same time prevents the structural defects of the pipelines and ensures the reliability of the pipeline laying quality.
