| Abstract: | Rock embedded bottom-enlargement pile is a kind of end bearing pile, the thickness of sediment at the pile bottom has direct impact on the bearing capacity of pile foundation. The paper introduces an engineering of rock embedded bottom-enlargement pile which is constructed by sediment clearing with rotary drilling machine. It is proved by practice that sediment cleaning with rotary drilling machine can reduce construction procedure, improve the efficiency of construction and ensure the construction quality of pile. |
