DESIGN AND CONSTRUCTION OF UNDER-REAMED BORED PILE AT JINDI TOWN INTERNATIONAL

介绍钻头设计思路,计算依据和制作技术要点。采用我公司自制的机械式扩底钻头进行扩底施工,可代替人工挖孔桩扩大头,收到了满意效果。

This paper introduced the train of thought for bore design, calculation basis and key points of the makiag technique. Mechanical under-reamed bore made by our company can be used for relevant construction instead of artificial digging and has been proved satisfactory.
