静压挤密桩工法在郑西铁路桥中的应用

Construction Technique of Static Compression Compacting Pile in Zhengxi Railway Bridge

介绍了静压挤密桩在处理地基过程中成孔、夯填等施工工艺。实践证明静压挤密桩施工技术提高挤密桩的工作效率,降低地基处理的成本,并能达到消除地基土的湿陷性,提高地基承载力的目的。它作为一种新的施工方法,有着显著的经济效益与社会效益。

The paper introduced contruction technique of static pressure compaction pile which apply for boring hole and ram filling of ground treatment. It is proved that the technology of static pressure compaction pile can enhance the efficiency, decrease the cost of the ground treatment, eliminate the collapsible nature of ground earth, and enhance the ground bearing capacity. It will produce great economic benefits and social benefits as a new method of construction.
