Bathroom floor drain embedded sewer line impermeability device

Abstract

The invention discloses a bathroom floor drain embedded sewer line impermeability structure device which comprises an embedded metal sleeve, a floor drain, an upper half outer tooth plastic pipe, a lower half outer tooth plastic pipe, an elastic plastic water-retaining adhesive tape and a sewer pipe, wherein an upper screw cap is arranged at the upper end of the embedded metal sleeve; a lower screw cap is arranged at the lower end of the embedded metal sleeve; the upper end of the upper half outer tooth plastic pipe is connected with the upper screw cap; the floor drain is arranged on the upper screw cap; the lower end of the lower half outer tooth plastic pipe is connected with the lower screw cap; the sewer pipe is connected to the lower end of the lower screw cap; and a distance is reserved between the bottom edge of the upper half outer tooth plastic pipe and the upper edge of the lower half outer tooth plastic pipe. Compared with the prior art, the bathroom floor drain embedded sewer line impermeability structure device disclosed by the invention adopts the design of similar deformation, elastic plastic gap filling and stress transfer decomposition, is simple in structure, good in impermeability effect, economic, durable, convenient to maintain and large in popularization space and is suitable for building bathroom floor drain sewer pipeline embedded sections.

Description

technical field [0001] The invention is an anti-seepage device for the pre-buried sewer pipe of the washroom floor drain designed for the sewer pipe in the pre-buried section under the floor drain of the restroom of a building that often seeps into the downstairs washroom, and belongs to the field of building water supply and drainage. Background technique [0002] At present, the sewer pipe material under the floor drain of the building toilet is basically PVC pipe and metal pipe. Because the metal pipe is easy to rust and corrode, the material of the sewer pipe under the floor drain of the building toilet is mostly PVC pipe at present, but the linear expansion coefficient of PVC pipe The linear expansion coefficient of concrete is quite different, especially after taking a hot bath, when the temperature difference changes greatly, the temperature stress is more likely to damage the bonding force between the PVC pipe and concrete, and the ground often accumulates in the hot ...

[0002] At present, the sewer pipe material under the floor drain of the building toilet is basically PVC pipe and metal pipe. Because the metal pipe is easy to rust and corrode, the material of the sewer pipe under the floor drain of the building toilet is mostly PVC pipe at present, but the linear expansion coefficient of PVC pipe The linear expansion coefficient of concrete is quite different, especially after taking a hot bath, when the temperature difference changes greatly, the temperature stress is more likely to damage the bonding force between the PVC pipe and concrete, and the ground often accumulates in the hot bath. Water, use the toilet absorber to absorb the accumulated water in the floor drain and drain the water. At this time, the PVC pipe in the concrete is pulled by the toilet absorber. In the water pipe section, shortly after use, water seepage often flows to the downstairs toilet along the cemented crack between the PVC pipe and the concrete, so there are deficiencies in the existing technology
