| Abstract: | On base of the 1.5 m rock socketed pile in the key pier of one cable stayed bridge canal-crossing,it introduces the pore-forming technique combined rotary drilling and percussion drilling from the aspects of system institution of slurry,hole site selection,canister inbuilt,pore-forming construction on cover level,and represents prevention and treatment measures of percussion drilling and pore-forming accidents,which will supply reference to the similar pile foundation construction in projects. |
