Foundation pit connecting position bottom plate waterproof structure and construction method
The invention discloses a foundation pit connecting position bottom plate waterproof structure and a construction method.The waterproof structure comprises an early foundation pit bottom plate and a later foundation pit bottom plate which are arranged side by side, the upper portion of the early foundation pit bottom plate is provided with a tongue-and-groove, and the early foundation pit bottom plate and the later foundation pit bottom plate are connected through the tongue-and-groove to form a Z-shaped contact face; a reinforcing layer is arranged on the lower portion of the contact face formed by the early-stage foundation pit bottom plate and the later-stage foundation pit bottom plate, a waterproof layer is arranged below the reinforcing layer and laid on the cushion layer, and the length of the waterproof layer is larger than that of the reinforcing layer. The later-stage foundation pit bottom plate and the early-stage foundation pit bottom plate are connected through the rabbets to form a Z-shaped contact face, the joint area of the two is greatly increased, the water seepage path is prolonged, and the waterproof performance is improved. The reinforcing layer is arranged on the lower portion of the contact face formed by contact of the early-stage foundation pit bottom plate and the later-stage foundation pit bottom plate, the waterproof layer is arranged below the reinforcing layer, and underground water is further prevented from leaking along the joint. The waterproof layer is longer than the reinforcing layer, so that raw materials are saved, and the cost is reduced.
本发明公开一种基坑相接位置底板防水结构及施工方法，其中防水结构包括并排设置的先期基坑底板和后期基坑底板，先期基坑底板上部设置为企口，先期基坑底板与后期基坑底板通过企口连接形成Z字型接触面；先期基坑底板和后期基坑底板形成的接触面下部设置有加强层，加强层下方设置有防水层，防水层铺设于垫层上，防水层的长度大于加强层。后期基坑底板与先期基坑底板通过企口连接形成Z字型接触面，极大的增加二者接缝面积，延长了渗水路径，提高防水性能。将加强层设置在先期基坑底板和后期基坑底板接触形成的接触面下部，在加强层的下方设置防水层，进一步防止地下水延接缝渗漏。且防水层的长度大于加强层，节省原材料，降低了成本。
