高喷桩基在大风江调水工程中的应用

Application of high pressure gunite technique in pile foundation construction of Dafengjiang water control project

介绍了大风江调水工程中的东场挡潮闸工程的基础及工程地质情况,分析了闸址地层岩性,提出了采用高压喷射灌浆技术形成较大直径桩基,提高挡潮闸两岸岸墙砂基础的地基承载力,并详细论述了高喷桩的设计、施工和质量控制。

An introduction is made on the foundation and engineering geological conditions of Dongchang tide gates, a component of Dafengjiang water control project. Based on an analysis on the lithologic character of gate site strata, high pressure gunite technique is adopted for the construction of pile foundation with large diameter, so as to improve the foundation bearing capacity of quay wall sand foundation at both sides of tide gates. A detailed introduction is made on the design, construction and quality control of high pressure gunite pile.
