孔内深层夯扩桩的注水施工

Pouring construction of deep tamping-expanding pile

结合工程实例,阐述了孔内深层夯扩桩在处理较深厚度湿陷性黄土中的应用,特别针对地基土含水量偏低的情况,介绍了孔内深层夯扩桩的注水法施工,以提高土体的含水量,确保工程施工质量。

With the practice of project,the application of deep tamping-expanding pile in treatment for the thicker collapsible loess area is discussed in this paper.Especially it is aimed at the foundation whose clay is in lower rate of the water inside,and the pouring construction for deep tamping-expanding pile is introduced,so as to raise the water content of the earth and ensure the constructing quality of the project.
