粉喷桩处理公路软土地基施工工艺与检测方法的探讨

Construction Technique and Detection Method Treating Highway Soft Base with Cement Injection Pile

粉喷桩是加固饱和软土地基的一种新方法,它以水泥为固化剂,通过搅拌使软土硬化成为具有整体性、水稳性和一定强度的优质地基。结合丹拉高速公路工程实例,探讨粉喷桩处理公路软土地基的施工工艺与检测方法,并对喷粉桩施工注意事项加以介绍,对同类工程的施工有很好的借鉴作用。

Cement injection pile is a new method consolidating soft soil base. It makes the soft soil harden, then becoming good base with integrity, water stability and strength through mixing. Integrating with Dandong-Lasa expressway, the construction technique and detection method treating high-way soft base through cement injection pile are discussed, and the items deserving attention are introduced. It can provide reference for the similar engineering.
