Background

The 'thirteen-five' planning in China greatly promotes the development of the assembled building, and the assembled building becomes the main direction of the future building development in China. Precast concrete floor systems play a vital role as the main components and constituent parts of fabricated buildings. However, at present, even in an assembled building, the bathroom floor is often a cast-in-situ floor, and the assembly degree is low, which is particularly remarkable in the same-layer drainage which is widely popularized and applied at present.

The same-layer drainage refers to that a drainage branch pipe is paved on the layer, namely a drainage pipe of equipment such as bathroom sanitary equipment does not penetrate through a floor slab, and the drainage branch pipe is connected with a drainage main pipe on the layer; if the drainage pipeline needs to be cleaned and dredged, the problem can be solved at the layer. The current common drainage modes of the same layer mainly comprise two types: the method is to lower the toilet bottom plate as a pipeline laying space, the submerged floor adopts cast-in-situ concrete and a waterproof layer is made, and all the drainage branch pipes are laid on the floor; the other is wall drainage, i.e. a transverse pipe is paved in a wall body decorated and decorated, and various sanitary ware adopts a side drainage mode.
