摘要
泵吸反循环钻孔扩底灌注桩与人工挖孔灌注桩相比,地质条件的适应性强,施工安全可靠。与直孔桩相比,其承载力高,经济性能显著。因此,泵吸反循环钻孔扩底桩的应用前景广阔。
Compared to artificial digging-hole pile, the pumping reverse-circulation under-reamed bored pile has higher adaptability to geological condition, and its construction is safety and reliability. Compared to ordinary pile , it has higher bearing capacity,and its economy capability is remarkable. As a result, the pumping reverse-circulation under-reamed bored pile has wider and wider using prospects.
