讨论公路路基处理中的粉喷桩技术的应用

To Discuss the Application of Powder Spraying Pile in the Treatment of Highway Subgrade

粉喷桩施工技术常见于承载力较弱的深层软弱地基施工加固中，该技术能够加强软土公路路基承载能力，同时也能降低路基沉降几率，所以常被应用于公路路基处理加固中。本文主要说明了粉喷桩施工方法及流程、提升粉喷桩施工质量的有效手段。

The construction technique of deep powder jet pile is common in the reinforcement construction of deep soft ground with weak bearing capacity, the technology can enhance the bearing capacity of soft soil roadbed of highway, and also can reduce the risk of subgrade setlement, is often used in the treatment of highway subgrade reinforcement. This paper mainly describes the method and process of powder jet pile construction, effective means to improve the construction quality of cement injection pile.
