以上海地区的软土地基为对象,介绍一种钻孔灌注桩施工的创新工艺。重点阐述和分析钻孔灌注桩施工过程中切削式成孔的机理以及采用低能耗的物理方法来解决泥浆脱泥问题的途径。从工程实践的效果来看,不仅减少了泥浆排放量,也加快了成孔速度,保证了桩体质量,是一种比较理想的绿色施工方式。 Taking the soft soil foundations in Shanghai as an example, this paper introduces an innovative process of bored pile construction. This paper mainly elaborates and analyzes the mechanism of cutting hole formation during the construction of cast-in-place bored pile and the way to solve the problem of mud desliming by using low-energy physical methods. From the effect of engineering practice, not only reduce the amount of mud emissions, but also speed up the hole speed, to ensure the quality of the pile is an ideal green construction methods.
