Description

Invisible drainage system and method and building wet area structure Technical Field The invention relates to the technical field of constructional engineering, in particular to a invisible drainage system and method and a construction wet area structure. Background In wet areas of buildings such as kitchens, toilets, balconies and the like, a ceramic tile (or stone) paving layer (comprising an adhesive layer and a rigid layer) can be used for storing water for a long time due to infiltration of domestic water and rainwater into gaps of the surface layer. Because the lower main structure floor slab is constructed with a complete waterproof layer, the water is sealed in the decorative structure filling layer, and cannot leak downwards. The water storage spreads to the surrounding walls under the capillary action, so that the phenomena of moisture regain, putty falling, moldy paint, damage of the finish layer and the like appear on the walls of adjacent rooms, and the use function and living health are seriously affected. The problem is particularly prominent when the waterproof layer is intact, and the traditional maintenance is difficult to radically cure. The existing solutions rely mainly on waterproof layers to "plug" or use traditional secondary drainage floor drains. The former can not remove accumulated water, and the latter is usually only aimed at the backfill layer of a caisson type toilet, has single drainage path and is easy to block, and is not suitable for non-caisson areas (such as balconies and kitchens) or light backfill processes, so that the problem of accumulated water in the tile paving layer can not be radically solved. Thus, there is a need for a invisible drainage scheme that actively, effectively and permanently drains accumulated water in each structural fill layer of a wet area of a building. Disclosure of Invention The invention aims to overcome the defects of the prior art, and provides a invisible drainage system, a structure and a method capable of actively draining accumulated water in a filling layer of a construction wet area structure, so that the problems of wall body moisture regain, mildew and the like caused by the accumulated water in the layer are fundamentally avoided. In order to achieve the above purpose, the present invention adopts the following technical scheme: an invisible drainage system comprises a water collecting part and a drainage main pipeline; The water collection portion having an interior cavity for admitting water and a water permeable wall in communication with the interior cavity, the water permeable wall being configured to permit water in the build-up fill layer to permeate while blocking solid particles; the main drain pipe is in fluid communication with the internal cavity of the water collection portion for draining the collected water. In order to obtain the effect of radically removing accumulated water in the filling layer of the structure and avoid the blockage of a drainage channel by solid impurities such as cement mortar, the invention constructs the water permeable wall of the water collecting part into a structure with a selective filtering function. The working principle is that after domestic water or rainwater infiltrates into the structural filling layer through the gaps of the ceramic tiles, the domestic water or rainwater can accumulate and spread in the layer. The water collecting part is pre-buried in the structural filling layer, and the water permeable wall of the water collecting part is in direct contact with surrounding structural filling layer materials (such as mortar and backfill ceramsite). Under the driving of gravity, capillary action and water pressure difference, the accumulated water in the structural filling layer can be gathered towards the water collecting part and penetrate through the water permeable wall to enter the inner cavity of the water collecting part, and solid impurities such as cement particles, dust and the like are effectively blocked outside the water permeable wall. The accumulated water entering the cavity is actively drained through the communicated main drainage pipeline (such as the main drainage pipeline or the transverse pipe of the building), thereby realizing that the drainage replaces pure blockage and eradicating the water storage source. In an alternative embodiment, the water collecting part comprises a vertical water collecting piece, and the water permeable wall is positioned at the upper area of the side wall of the vertical water collecting piece. In an alternative embodiment, the upper end of the vertical water collector is configured to be connected to a floor drain panel or a floor drain core. In an alternative embodiment, the water collecting part further comprises a water collecting pipe, the pipe body end of the water collecting pipe is provided with a water permeable structure, the water permeable structure is configured to allow water in the construction filling layer
