摘要
介绍了一种主要用于基坑帷幕隔水和土体加固的新型长螺旋搅喷桩及其桩径与土层、施工工艺参数关系的试验研究成果。提供了用于指导施工的施工工艺参数和先施工长螺旋搅喷桩后施工钢筋混凝土护坡桩的建议。对基坑支护及地下水控制设计有重要参考价值。
This paper introduces a new type of long spiral mixing jet grouting pile which is mainly used for pit water- proof curtain and soil reinforcement. This paper summarized the relationship of pile diameter with the soil and construction pa- rameters. The experimental research results not only provides guidance on construction parameters, but also suggests construc- ting the long spiral mixing jet grouting pile first then constructing the reinforced concrete revetment pile. This article provides an important reference for the foundation pit support and groundwater control design.
