首钢迁钢冷轧项目四区取向成品退火生产线工程,基础承载层地质情况为砂质土层,为提高基础承载力,采用长螺旋钻孔内泵压混凝土CFG桩复合地基,结果表明:采用该技术后,结构承载力明显提高,满足设计要求。

Shougang Qiangang Cold Rolling Project four regions oriented finished annealing line project, the basic bearing layer of the geological conditions of sandy soil, in order to improve the basic carrying capacity, the use of long spiral borehole pressure concrete CFG pile composite foundation, the results show that: the use of the After technology, the bearing capacity of the structure is obviously improved to meet the design requirements.
