灌注桩成孔采用两种不同机械设备联用施工技术

Construction technology of two kinds of different mechanical equipment used in the hole filling pile

结合海口市南片区安置房工程地质情况及灌注桩设计要求,提出了冲击成孔机械与正循环磨盘钻机联用成孔工艺,并阐述了具体的施工方法,经实践证明,该工艺取得了显著的经济社会效益。

Combining with the geological status of relocation project in Nanpian District of Haikou City and the design demands for the bored piles,the paper points out the dynamic holing mechanism and the direct cycle millstone driller holing craft,illustrates the construction methods,and proves by the practice that the craft achieves better economic and social benefits.
