Discussion on Long Spiral Mixing Waterproof Curtain Interlocking Pile and the Construction Practice

Abstract:

The paper introduces the construction process of long spiral mixing waterproof curtain interlocking pile, which breaks the construction limitation of original mixing pile and curtain of rotary jet grouting in hard soil areas with lower construction cost, and especially has advantage for the curtain in shallow excavation. Based on the engineering case of the excavation for an underground garage in Beijing, the curtain construction was proved to be an appropriate technology.
