摘要
地下连续墙俗称地连墙,是基础工程在地面采用挖槽机械,沿开挖工程基坑边线,在泥浆护壁条件下,挖出一条狭长的深槽,在槽内吊放钢筋笼,用导管法灌注水下混凝土筑成一个单元槽段,起截水、防渗、称重、挡水作用。在我国上海地区普遍应用,多用于大型深基坑工程。目前,地下连续墙最大的开挖深度为140m,最薄的地下连续墙厚度为0.2m,在我国已经是一种趋于成熟的施工工艺。
Underground continuous wall known as the diaphgram wall is a foundation projcet by dredging machinery on the ground , which is to dig a narrow deep groove along the sideline of the foundation pit excavation under the slurry-supported conditions, and then, containing a steel reinforcement cage in the groove,make into a single unit groove section with underwater concrete catheter perfusion to pay a part in cutoff water, seepage control, bearing, and water retaining.This project is widely used in China＇ s Shanghai region, and more for large and deep foundation pit engineering. At present, the underground continuous wall excavation depth is 140m maximum, and the thinnest underground continuous wall is 0.2m. In China ,it is already a mature construction technology.
