| Abstract: | It is introdeuced that the long spiral rotary spray mixing piles were used on Beijing metro deep foundation pit engineering. When there were hard underground obstacles, the pneumatic DTH hammer was applied. It can drill the obstacles easily. The waterproof curtain piles were drilled smoothly,. The construction technique provides references for similar or related projects in the future. |
