泥浆护壁钻孔灌注桩施工及监理

Construction of slurry-protective-wall cast-in-site bored pile and monitoring

针对施工过程中钻孔灌注桩存在的问题,从孔径、泥浆、孔的垂直度、孔深、沉渣与沉淤等方面对钻孔灌注桩施工中影响承载力的施工及监理要点进行了分析,并对钢筋笼加工与吊装、混凝土灌注等工序作了阐述。

According to the problems existing in the construction of cast-in-site bored pile, it analyses the factors that influence power bearing ability from bole diameter, mud, the verticality of hole, hole depth, sediment and silting and key monitoring points, and illustrates the pro- cessing and hoisting of reinforced cage, concrete piling and other procedures.
