Underground diaphragm wall and construction method thereof
The invention provides an underground diaphragm wall and a construction method thereof. The underground diaphragm wall comprises a cement soil waterproof curtain, prestressed pipe piles and an assembled steel pipe component; and the assembled steel pipe component is driven into the cement soil waterproof curtain, the prestressed pipe piles are arranged in a steel pipe component unit, and the centers of closed surfaces formed on the cross section of the steel pipe component unit coincide with the centers of the prestressed pipe piles. The underground diaphragm wall has the characteristics of being simple in construction technology, high in construction progress, low in building cost, good in waterproof effect and the like, mud and other waste are not generated in the construction process, and the underground diaphragm wall is suitable for deep foundation pit support engineering of an underground diaphragm wall serving as an underground outdoor wall in various soil textures of foundations.
本发明提供一种地下连续墙及其施工方法。所述地下连续墙包括水泥土止水帷幕、预应力管桩及装配式钢管构件，在水泥土止水帷幕中打入装配式钢管构件，预应力管桩设置在所述钢管构件单元内，所述钢管构件单元横截面上形成的闭合面的中心与所述预应力管桩的桩心重合。本发明具有施工工艺简单、施工进度快、建造成本低、止水效果好等特点，施工过程不产生泥浆等废弃物，适用于各类土质地基中兼作为地下室外墙的地下连续墙的深基坑支护工程。
