软土区旋喷式插筋微型桩工艺试验研究

Experimental Research on Jet Grouted Micro Piles in Soft Soil Area

软土地质条件下建筑物的沉降变形和承载力要求越来越高,对基础施工工艺提出了较高要求。在高压旋喷施工工艺的基础上,提出旋喷式插筋微型桩施工工艺,开展了微型桩工艺试验研究,结果表明该工艺大幅提高了单桩桩基承载性能,为实际工程应用提供了技术数据支持。

Under the condition of soft soil,the requirements of buildings on settlement deformation and bearing capacity are getting higher and higher,leading to higher requirements on the foundation construction.Based on the high-pressure jet grouting process,the micro-pile construction process with jet grouting was proposed,and tested. The results show that the process greatly improves the bearing capacity of the single-pile pile foundation and provides data support for field applications.
