用喷粉桩加固软土地基的探讨

Discussion of Reinforcement of Soft Soil Subgrade Using DJM Piles

喷粉桩加固软土技术主要适用于处理淤泥、淤泥质土、粉土和含水量较高的粘性土,以及能成桩的杂填土。广泛应用于地基加固,桩基础,深基坑支护等方面。喷粉桩桩机的体型小,操作方便,取材容易,施工速度快,能完成狭小空间的地基处理,因此深得社会各界的好评。下面就本人在工程实践中的体会对设计和施工中应注意的问题进行探讨。

The technique to reinforce soft soils using DJM piles is mainly applicable to treatment of mire, sludge soil, silty soil, cohesive soil with a high moisture content and complex earth-filL This techmique is widely used to reinforce subgrade, pile foundation and supporting of deep foundation pit. The drilling machine for DJM piles has the advantases of small volume, convenient opperation, easy material resource, high construction speed and operation in a small space. This paper disusses the problems to which persons should pay attention when they make design and construction of DJM piles.
