Abstract

The invention provides an anti-seepage squatting pan modified toilet structure and a construction method thereof, and relates to the technical field of anti-seepage. The water accumulation funnel and the floor drain funnel form an inner-outer double-layer nested structure, the floor drain funnel is used as an upper drainage channel for draining water accumulated on the surface of the decorative surface layer, and the water accumulation funnel is used as a lower drainage channel for collecting water leakage leaking downwards from the leveling layer. The outer diameter of the water outlet end of the floor drain funnel is smaller than the inner diameter of the water accumulation funnel connecting pipe, an annular gap is formed between the two layers, so that two layers of drainage paths are mutually independent. Even the upper floor drain funnel is blocked by sundries, the lower water seepage can still be discharged through the annular gap, so that the problem of internal ponding caused by blockage is avoided.

Description

Anti-leakage squatting pan structure and construction method thereof Technical Field The invention relates to the technical field of antiseep, in particular to an antiseep squatting pan-changing toilet structure and a construction method thereof. Background Along with the change of the population structure of the family and the improvement of the living standard, more families need to carry out toilet reconstruction, and the original squatting urinal which is originally installed is replaced by a toilet. The toilet bowl accords with the human engineering design, can lighten the burden of legs when in toilet, and is particularly suitable for families with old people, knee joint discomfort people or mobility-impaired people at home. Therefore, the original squatting pan has become a common home decoration requirement for changing the toilet bowl. The existing original squatting urinal is changed into a toilet in a transformation mode, namely, the original squatting urinal and the surrounding tiles are smashed, original drain pipes are reserved, pipelines are paved in the installation groove again, backfilling and leveling are carried out, and finally, the tiles are paved and the toilet is installed. However, the modification has the obvious defect that water is easy to accumulate in the modified structural layer. Because the gaps between the base and the ceramic tile, between the ceramic tile and the mortar layer and between the pipeline and the structural layer are difficult to completely seal after the toilet is installed, daily cleaning water or toilet ground water can infiltrate into the mortar layer below through the gaps. The permeated water is accumulated in the structural layer and cannot be discharged in time, and accumulated water is formed after long-term retention. Along with the continuous increase of water accumulation, water can finally permeate downwards through cracks or weak structural parts of the floor slab, so that the problems of leakage, mildew, peeling and the like of ceilings of residents under the building occur, and economic losses of neighborhood disputes and repeated maintenance are caused. Therefore, the anti-seepage squatting pan structure and the construction method thereof are provided.
