粉体喷射搅拌桩处理软土地基施工技术

粉体喷射搅拌桩处理软土地基技术是加固软土地基的一种新方法,应用于软基段的高路堤、桥梁、结构物的基础和两侧,经加固处理后的粉喷桩主体与周围地基共同作用构成复合地基,提高了地基承载能力,增加了路基和结构物的稳定性。对粉喷桩所用设备的性能、施工工艺、结构物的布桩形式、质量保证措施、施工组织、现场施工记录及检测项目、质量标准均作了较详细的介绍。

Treatment of Soft Soil Foundation with Dusted Pile

The treatment of soft soil foundation with dusted Pile is a new method reinforcing the soft soil foundation,which is applied to the foundation and both sides of high embankment,bridge and structure at lot of soft soil foundation.The reinforced dusted pile with surrounding foundation constitute the recombination foundation under their joint action,increasing the bearing capacity of foundation,adding the stability of subgrade and structure.The paper particularly introduces the performance of equipment applied by dusted pile,the construction technology,the form of structure arranging,the measures for quality guaranteeing,the construction organization,the records for field construction,the detected items along with the quality standards.
