摘要
介绍了长螺旋钻孔内泵压CFG桩的质量控制方法的测量放线、桩长的控制、混合料压灌控制等关键环节 ,指出CFG桩复合地基因具有承载力提高幅度大、造价低的特点 ,在中高层建筑中将得到广泛应用。
The quality control method of pressure pumped CFG piling by continuous auger drilling is introduced, from survey, length control of pile and pouring control of mixture the key links of construction are elaborated. The composite foundation with CFG piling will be wildly applied in the construction of high-rise building with its low cost and large bearing capacity.
