Introduction: The water-proof sleeve used in the waterworks is fixed in the wall or plate. According to the area (such as pool, septic tank, basement, etc.) to avoid the leakage or leakage of liquid, the waterproof wing shall be lifted at least 1 circle on the surface of the casing, so that the water plant can use the waterproof sleeve to pour

For Waterworks Waterproof casing It is fixed in the wall or plate. According to the area where liquid leakage or leakage is avoided (such as pool, septic tank, basement, etc.), the waterproof wing of no less than 1 circle shall be lifted on the surface of the casing pipe. In this way, when the waterproof sleeve is poured into the wall body of the water plant, it will not be easy to leak due to cracks caused by expansion and contraction.
Before sand blasting and derusting, check whether the ovality, thickness and material of all waterproof sleeves used in Waterworks meet the material standards, otherwise, they can not be applied. The paint, grease, oxide, etc. on the surface of the pipeline shall be removed during sand blasting and derusting, which shall be approved by QC department and the owner and recorded well before anticorrosion and painting. The anti-corrosion of pipeline shall be carried out according to the drawing and standard requirements of waterproof casing used in waterworks.
Before painting, the top coat shall be mixed sufficiently, and the dust and moisture on the surface of the pipeline shall be removed by pure cotton gauze or air compression. The waterproof sleeve used in the water plant for rust removal on the same day must be painted with one coat of top coat on the same day. Before the first finish coat is dry, two coats of top coat shall not be applied. The primer on the surface layer of pipeline shall be uniform and free of leakage. There is no need to paint 50 mm above the two sides of the pipeline. The pipes with the same specification, model, thickness and material should be put together for rust removal as much as possible. After rust removal, identification and colonization should be made for each pipe. After finishing painting, each pipe must be marked for colonization. After rust removal and painting, both sides of water-proof casing used in Waterworks shall be sealed. Protection measures shall be taken to avoid damage of pipeline coating during transportation and lifting.
There is a pipe connection between each pool in the water plant, and the drinking water transportation should be applied to the pipeline. When the pipe passes through the pool wall, the water-proof protective pipe should be protected by the water-proof sleeve. Concrete pouring is to be one-time pouring molding, the scope of pouring should also be done, the standard atlas of water-proof casing used in waterworks, in addition, the material of water-proof casing used in Waterworks must be stainless steel, and can not be sprayed. Because of the harmful substances in the paint, if used in the waterworks, it will affect the water quality. In waterworks, there are more waterproof sleeves available, mainly due to the high waterproof requirements of the water plant. Once the water plant pipeline fails, the water supply is cut off for maintenance, which will lead to the trouble of drinking water for residents. In order to avoid problems in later maintenance, it is necessary to strictly follow the process and adopt the suitable waterproof casing type to wake up the concrete pouring.
