An anti-seepage structure device for pre-buried sewer pipes in toilet floor

Abstract

The invention discloses a restroom floor pre-buried sewer pipe anti-permeability structure device comprising a sewer pipe mounted on a restroom floor, a stainless steel lining casing pipe, an upper stainless steel seal cover, an upper colloid anti-permeability ferrule, a plastic film water bag, a lower colloid anti-permeability ferrule, a lower stainless steel seal cover, a bottom water seepage box and a V-shaped water seepage diversion pipe; the sewer pipe is located in the stainless steel lining casing pipe; the upper stainless steel seal cover is connected between the sewer pipe and the stainless steel lining casing pipe and is located at the upper end of the stainless steel lining casing pipe; the lower stainless steel seal cover is connected between the sewer pipe and the stainless steel lining casing pipe and is located at the lower end of the stainless steel lining casing pipe; the plastic film water bag is arranged between the upper stainless steel seal cover and the lower stainless steel seal cover. Compared with the prior art, the device adopts design of classification seepage prevention, bag mold seepage prevention and water seepage backflow, has the advantages of simple structure, good anti-seepage effect, and convenience in maintenance, and is economic and durable, suitable for building restroom floor pre-buried section sewer pipes, and large in promotion space.

Description

technical field [0001] The invention is an anti-seepage structural device for the pre-buried sewer pipes on the floor of the washroom designed for the frequent leakage of the pre-buried sewer pipes on the floor slabs of the restrooms, and the seepage seeps into the downstairs washrooms. It belongs to the field of house construction water supply and drainage. Background technique [0002] At present, in buildings built around 2000, PVC pipes are mostly used as pre-embedded sewer pipes in toilet floors. However, the linear expansion coefficient of PVC pipes is quite different from that of concrete. When the temperature difference changes greatly, the temperature stress is easier. Reduce the bonding force between the PVC pipe and the surrounding concrete. When the floor accumulates water, use the absorber to drain water, and the PVC pipe in the concrete is subjected to the pulling force of the absorber, which further reduces the bonding effect between the PVC pipe and the surro...

[0002] At present, in buildings built around 2000, PVC pipes are mostly used as pre-embedded sewer pipes in toilet floors. However, the linear expansion coefficient of PVC pipes is quite different from that of concrete. When the temperature difference changes greatly, the temperature stress is easier. Reduce the bonding force between the PVC pipe and the surrounding concrete. When the floor accumulates water, use the absorber to drain water, and the PVC pipe in the concrete is subjected to the pulling force of the absorber, which further reduces the bonding effect between the PVC pipe and the surrounding concrete. Therefore, the toilet Soon after use, water seepage often flows to the toilet downstairs along the glued crack between the PVC pipe and the concrete, so there are deficiencies in the existing technology
