| Abstract: | 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. |
