Construction method of underground diaphragm wall and underground diaphragm wall
The invention provides a construction method of an underground diaphragm wall and the underground diaphragm wall. The construction method specifically comprises the following steps that two grid structures are fixed to the two sides of the paying-off position of the underground diaphragm wall so as to achieve the wall guiding effect on the underground diaphragm wall; a cement soil waterproof curtain is arranged at a preset position of the underground diaphragm wall; before cement soil in the cement soil waterproof curtain is not condensed, pipe piles and steel pipe components are driven into the cement soil waterproof curtain; and after all the pipe piles and the assembled steel pipe components are driven, laitance on the surface of the wall top of the underground diaphragm wall is removed, and inner cavities of the pipe piles are filled with cement mortar. The underground diaphragm wall is constructed through the construction method. The construction method and the underground diaphragm wall have the advantages that the construction technology is simple, the construction progress is fast, the construction cost is low, and the waterproof effect is good; and in the construction process, waste such as mud is not generated, and the construction method is suitable for deep foundation pit supporting projects of various soil foundations.
本发明提供一种地下连续墙的施工方法及地下连续墙。施工方法具体包括以下步骤：将两个网架结构固定于地下连续墙放线位置的二侧，以实现对地下连续墙的导墙作用；在地下连续墙的预设位置设置一道水泥土止水帷幕；在水泥土止水帷幕内的水泥土未凝结前，向水泥土止水帷幕内打入管桩和钢管构件；在打完所有管桩和装配式钢管构件后，清理地下连续墙墙头表面浮浆，用水泥砂浆填实管桩的内腔。地下连续墙使用上述施工方法建造而成。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的深基坑支护工程。
