自立式钻孔灌注桩深层搅拌桩组合体系作软土地基深基坑支护结构

The Adoption of two-in-One Combination of Bored Pile and Deep Stirred Pile as Self-Support Structure for Soft-Soil Deep Foundation Pit

在深层搅拌桩体中打入钻孔灌注桩使之构成一体,共同挡土和止水,再在顶部加设钢筋混凝土环板形成自撑式深基坑支护结构。

Deep stirred pile plus bored pile makes a monolithic body to retain soil and water. Together with reinforced concrete ring beam poured on the piles' top, self-support structure of deep foundation pit is thus formed.
