Synchronous construction method for adjacent foundation pits
The invention provides a synchronous construction method for adjacent foundation pits. The synchronous construction method for the adjacent foundation pits comprises the following steps that a middle partition wall is constructed and formed, an area in which a first foundation pit and a second foundation pit are to be formed is excavated, a plurality of concrete supports on the first foundation pit along the excavation depth are erected, and a plurality of steel supports on the second foundation pit are erected; a first floor slab is formed in the position, corresponding to the bottom face of the second foundation pit, in the first foundation pit through pouring, and a second bottom plate is formed at the bottom of the second foundation pit through pouring; the steel support located below the topmost steel support in the second foundation pit is dismantled, and a protection wall is formed on the top face of the second bottom plate in a pouring mode; a plurality of inclined struts are obliquely supported between the protection wall and the second bottom plate, and the steel support located on the topmost portion is dismantled; and the part, higher than the bottom face of the second foundation pit, of the middle partition wall is removed, the concrete support is removed, and concrete is poured between a first floor and the second bottom plate to form a connection section. The side walls of the foundation pit are supported through the inclined struts, so that part of the middle partition wall can be conveniently dismantled, and synchronous construction can be conveniently carried out at the position with the same elevation as the second foundation pit.
本发明提供了一种相邻基坑的同步施工方法，包括：施工形成中隔墙，开挖待形成第一基坑和第二基坑的区域，并沿开挖的深度于第一基坑支设若干混凝土撑，并于第二基坑支设若干钢支撑；于第一基坑内对应第二基坑的底面的位置浇筑形成第一楼板，于第二基坑的底部浇筑形成第二底板；拆除第二基坑中位于最顶部的钢支撑下方的钢支撑，于第二底板的顶面浇筑形成防护墙；将若干斜撑倾斜地支撑于防护墙和第二底板之间，将位于最顶部的钢支撑拆除；拆除中隔墙高于第二基坑的底面的部分，并拆除混凝土撑，于第一楼板和第二底板之间浇筑混凝土形成接驳段。本发明通过斜撑顶撑基坑的侧壁，方便将部分的中隔墙拆除，便于与第二基坑标高相同的位置进行同步施工。
