Undermining floor drain automatic drainage structure capable of preventing leakage of toilet

Abstract

The invention discloses an undermining floor drain automatic drainage structure capable of preventing leakage of a toilet and relates to a leakage-proof building structure. The automatic drainage structure comprises a reinforced concrete floor slab which is arranged at the bottom of the toilet and a vertical drainage pipe which penetrates through the reinforced concrete floor slab, wherein a drainage floor drain which does not protrude out of the upper surface and the lower surface of the reinforced concrete floor slab is embedded in the reinforced concrete floor slab, the whole drainage floor drain is in a tobacco pipe structure, a gird type floor drain cover is arranged on the water inlet of the drainage floor drain, a slope layer is arranged on the upper surface of the reinforced concrete floor slab, the water inlet of the drainage floor drain is communicated to the lowest position of the slope layer of the upper surface of the reinforced concrete floor slab, and the water outlet of the drainage floor drain is communicated into the vertical drainage pipe. The drainage structure has the advantages of being capable of preventing the leakage of the toilet effectively, low in construction difficulty and low in construction cost.

Description

technical field [0001] The invention relates to a building leak-proof structure, in particular to an automatic drainage structure for preventing toilet leakage. Background technique [0002] At present, for the convenience of use, most of the bathrooms adopt a sunken pit design (such as Figure 5 shown). The specific method is as follows: the toilet floor sinks into the toilet surface 550mm-600mm, the four walls and the bottom plate in the pit are waterproofed, the four walls are provided with a waterproof layer 12, the toilet 13 and the sinking water bend 17 are installed in the pit, and the pit is made of light materials. For filling, the concrete cushion layer 15 on the surface of the slab is pasted with floor tiles 16 . With this design and construction, there is a common quality problem of water leakage in the bathroom. Once water leakage occurs, it is necessary to dig out the concrete of the panel cushion 15, dig out the filling material 14 and the toilet 13, and re-w...

Problems solved by technology

However, even if the patent application performs secondary leveling and sets three waterproof layers, it may not be able to achieve a real waterproof effect. In the end, it is still necessary to set up a drainage conduit to drain the accumulated water in the pit to achieve the purpose of preventing toilet leakage.

Moreover, due to the use of concave concrete skeleton layered water drainage, the construction difficulty and structural load are increased; the use of multiple layers of ash and waterproof makes the process too complicated; compared with the existing design, the construction cost will be greatly increased

It can be seen that although the patent application technology can prevent toilet leakage, it is not conducive to widespread promotion and application because of too many processes and excessive construction costs
