Dewatering well-free dewatering construction method for deep foundation pit
The invention discloses a deep foundation pit dewatering-well-free dewatering construction method which comprises a foundation, a foundation pit body is formed in one side of the top end of the foundation, a sand basin is formed in the other side of the top end of the foundation, a self-priming pump is fixedly installed in the middle of the top end of the foundation, and a plurality of first drainage pipelines extending to the outside are fixedly installed in a U-shaped groove. The bottom end of the inner wall of the foundation pit body and the four sides of the inner wall of the foundation pit body are each provided with a plurality of blind ditches. According to the deep foundation pit dewatering-well-free dewatering construction method, a foundation pit outer facade layer is composed of a stone concrete layer at the bottom, a solid brick tire layer on the upper portion and a waterproof mortar plaster layer on the outer facade; the geotextile, the concrete pad and the filling layer are arranged to improve the water filtering and draining efficiency of the foundation pit body, and the deep foundation pit bedrock fissure water drainage problem can be rapidly, efficiently and reliably solved by communicating the self-priming pump, the extraction pipe and the conveying pipe and communicating the extraction pipe with the water collecting pit.
本发明公开了一种深基坑免降水井降水施工方法，包括地基，地基顶端的一侧开设有基坑本体，地基顶端的另一侧开设有沉沙池，地基顶端的中部固定安装有自吸泵，U形沟槽的内部固定安装有若干个延伸至外界的第一排水管道，基坑本体内壁的底端和基坑本体内壁的四侧均开设有若干个暗沟，本发明一种深基坑免降水井降水施工方法，基坑外立面层由底部的石砼层、上部的实心砖砖胎层，以及外立面的防水砂浆抹灰层构成，通过设置土工布、混凝土垫和填充层用来提高基坑本体自身的滤水、排水效率，通过自吸泵、抽取管和输送管，抽取管与集水坑相连通能快速、高效、可靠的解决深基坑基岩裂隙水降排水问题。
