深基坑止水帷幕施工工艺探索

Construction Technology of Water Curtain for Deep Foundation Pit

本工程通过工艺创新,利用机械搅拌和气液压力拌合的双重作用,实现了水泥浆液与土体的充分混合与支护桩共同起到挡土、止水结构,与传统的高压旋喷施工工艺或混凝土连锁桩施工工艺对比,提高施工效率,降低了施工成本,缩短了施工工期,降低了工程造价。

We introduced a technique innovation of water curtain for deep foundation pit by mechanical agitation and gas-liquid pressure mixing, which improved the construction efficiency, shortened the construction period and reduced the engineering cost.
