浅谈超厚砂层止水帷幕的应用

Discussion on the application of the Extra-thick Sand Layer Waterproof Curtain

介绍在超深基坑的支护主体外围设置连续的止水帷幕,根据目前最常用的深层搅拌桩和高压旋喷桩在超厚砂层的施工过程和成桩质量对比,区分这两种桩在遇到超厚砂层的机械选择。

This paper introduces the super deep foundation pit supporting body is arranged in the periphery of continuous waterproof curtain.Compared with the most commonly used with deep mixing pile and high pressure rotary jet grouting pile in thick sand layer and construction process of the pile quality comparison,to distinguish the mechanical selection when meeting the extra-thick sand layer.
