Toilet floor pre-embedded sewer pipe anti-seepage structure device

Abstract

The invention discloses a toilet floor pre-embedded sewer pipe anti-seepage structure device. The toilet floor pre-embedded sewer pipe anti-seepage structure device comprises a toilet floor and a sewer pipe arranged on the toilet floor, and a stainless steel lining sleeve, a trapezoidal cross-section water stopping rubber gasket, an inversed-trapezoidal cross-section water stopping rubber gasket, a bottom water seepage box, an elastic clamping ring and a stainless steel sealing cover are arranged in the toilet floor; and the elastic clamping ring is arranged between the inversed-trapezoidal cross-section water stopping rubber gasket and the stainless steel sealing cover, the trapezoidal cross-section water stopping rubber gasket is arranged on the bottom face of the stainless steel lining sleeve and connected with the peripheral face of the stainless steel lining sleeve, and the inversed-trapezoidal cross-section water stopping rubber gasket and the trapezoidal cross-section water stopping rubber gasket are oppositely arranged. Compared with the prior art, clamping ring concretion, elastic pressing, wedge-shape rubber body low-gravity-center stabilization, high-gravity-center drooping extrusion, seeped water backflow and other design are adopted in the toilet floor pre-embedded sewer pipe anti-seepage structure device, the structure is concise, the anti-seepage effect is good, the toilet floor pre-embedded sewer pipe anti-seepage structure device is economical, durable, convenient to overhaul and suitable for toilet floor pre-embedded sewer pipes of a building, and the popularization space is large.

Description

technical field [0001] The invention is a wedge-shaped water-stop and anti-seepage structure device designed for the pre-buried sewer pipes on the floor of the toilet of the building, which often leaks and seeps into the downstairs washroom. It belongs to the field of water supply and drainage of housing construction. Background technique [0002] At present, most of the pre-buried sewer pipes in the buildings built around 2000 are mainly made of PVC pipes, but 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 is flooded, the suction is used to drain the water, and the PVC pipe in the concrete is subjected to the pulling force of the suction, which further reduces the bonding effect between the PVC pipe and the surrounding concrete. Therefore, the toilet Shortly afte...

Problems solved by technology

[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
