水泥搅拌桩地基处理的施工及检测方法

The Construction and Testing method for Foundation Treatment of Cement Mixing Pile

水泥土搅拌桩是处理不良地基的一种实用方法。在实际施工中,应注重水泥土搅拌桩的施工参数、几何参数达到设计要求,在使用锚桩反力法检测水泥土搅拌桩承载力时,地锚钻进深度根据桩周实际情况确定,而机械锚具的应用也大大增加了锚桩抗拔力,根据沈阳市区经验,铁西区单锚抗拔力大于5吨,沈北新区单锚抗拔力2—3吨之间。

The cement mixing method is a practical method of foundation treatment. In the construction of cement mixing pile foundation, the construction parameters and the geometry parameters must fit to the requiring of designing. At testing bearing capacity of cement mixing pile foundation by anchor counterE- force method, the drilled depth of anchors is needed according to the fact, and the uplift force of anchor pile foundation is more increased by using mechanical anchor. On the basis of experience of Shenyang city, the uplift bearing load of a anchor is larger than 5 ton in Tiexi district, and the uplift bearing load of a anchor is 2-3 ton in Shenbei district.
