Description
Technical Field
The invention relates to the field of building water supply and drainage, in particular to an installation method of a secondary drainage device in a toilet.
Background
Since the national housing and urban and rural construction department encouraged the promotion of the full-dress refinish house, the leakage problem of the toilet after delivery of the fine-dress refinish house troubles developers and house purchasers.
In order to improve the construction efficiency of the full-assembly repair room of the newly-built commercial residential building and reduce the cost, the toilets of the full-assembly repair room basically adopt a different-layer drainage mode. The leakage condition of the whole house under the building is less, but the phenomenon that the wall surface of the house near the toilet is wet is continuous; this indicates that the ground part waterproof layer of the waterproof caisson of the full-installed repair room toilet, including the waterproof layer between the floor slab and the pipeline, is qualified.
At present, the bed course adopts dry cement mortar more when the ceramic tile of floor is being spread to the bathroom, like this if will lead to producing ponding in dry thick liquid layer when the ceramic tile gap infiltration, long-term, ponding fill the waterproof caisson of bathroom after, water will be along the ceramic tile adhesive linkage of bathroom wall to eight directions infiltration, and waterproof layer where has the gap, and moisture will permeate there, and the phenomenon of getting damp will appear in adjacent wall.
How to reduce the water level of accumulated water accumulated in the waterproof caisson of the toilet becomes the research focus of various large building design institutes and building decoration companies.
Patent numbers: ZL 201410071557.4 discloses a construction method for secondary drainage of a toilet, which is characterized in that the traditional caisson is made into a waterproof layer with a slope, and a through hole with the diameter of 10mm is drilled at the root of the sewer pipe of a wash basin; therefore, the purpose of secondary drainage is achieved, but the drilling of the method can damage the bonding between the waterproof layer and the water pipe in the waterproof caisson, the waterproof layer and the water pipe can be mildewed for a long time to cause the waterproof layer and the water pipe to be separated, water can finally leak to the next layer along the gap water to form water leakage, and the method is difficult to ensure the long-term waterproof quality.
Patent number ZL202010386896.7 secondary floor drain connection structure and construction process' of a formula of sinking bathroom will make vertical water guide well, and its construction is complicated and still need special dark floor drain to insert in the buried sleeve pipe in advance, has reduced the diameter of former water pipe, influences normal drainage.
Patent numbers: ZL 201920878888.7 discloses a dark floor drain for preventing the floor of the indoor and outdoor walls from being wet and preventing saturated water from overflowing, the technology can greatly reduce the diameter of a raw water pipe and influence normal drainage; patent number ZL201921621204.1 "a bathroom ground waterproof construction" also can realize secondary drainage, but this technique also can reduce the diameter of water pipe by a wide margin, influences normal drainage.
Patent numbers: ZL 201720652712.0 drainer and drainage system can realize secondary drainage, and the technology has patent products, but when the patent products are used, firstly, a water pipe is cut off in situ by adhering to a waterproof layer, and then the product is inserted into a floor drain downpipe for use; cutting off the original water leakage pipe by adhering to the waterproof layer can affect the adhesion between the waterproof layer and the floor drain downpipe, and the diameter of the original water pipe is greatly reduced by the product of the patent: for example, the cross section area of a floor drain downpipe with the inner diameter of 75mm is 44.18 square centimeters, the minimum caliber of a 75-type product is only 56mm, the cross section area is only 24.62 square centimeters, and the water flow is reduced by nearly half; the cross section area of a floor drain downpipe with the inner diameter of 50mm is 19.63 square centimeters, the minimum caliber of a 50-type product is only 34mm, the cross section area is 9.07 square centimeters, the water flow is reduced by half, and safety hazards obviously exist when full design load drainage needs to be carried out for a long time.
