Architecture indoor single-stack drain system and mounting method thereof

Abstract

The invention provides a building indoor single-standpipe drainage system, which includes an indoor standpipe, a water collection pipe, a pipe joint connected to the water collection pipe, a sanitary appliance socket and a floor drain arranged in the sanitary appliance socket. The drainage system includes a plurality of upper and lower A connected single-layer drainage unit, the single-layer drainage unit includes an indoor riser, a special insertion bucket for crossing the floor, a drainage insertion bucket for crossing the floor, a water collection pipe and a telescopic pipe joint connected to the lower indoor riser, and the lower end of the indoor riser is inserted It is installed in the special bucket for crossing the floor. The lower end of the special bucket for crossing the floor is inserted in the water collection pipe. The lower end of the water collection pipe is inserted in the telescopic pipe joint. The lower end of the cross-floor drainage bucket is inserted into the pipe joint. The drainage system and its installation method have the advantages of simple structure, convenient installation, cleanable floor drain, good water flow capacity, etc., great market promotion potential, and good economic and social benefits.

Description

technical field [0001] The invention relates to a drainage system and an installation method thereof, in particular to a building indoor single riser drainage system and an installation method thereof, belonging to the field of building water supply and drainage. Background technique [0002] At present, the indoor drainage system of the building is composed of a long vertical pipe from top to bottom and a horizontal pipe connecting the water appliances of each household toilet. The washing machine and ground water are discharged into the standpipe through the floor drain connected to the horizontal pipe, and then the water is discharged through the standpipe. At present, the indoor drainage system of buildings and its installation methods have the following problems: [0003] (1) The floor drain is fixed on the concrete floor and cannot be taken out for cleaning, which has its own hygiene problems and affects the smooth drainage. The floor drain is the interface that disc...

Problems solved by technology

[0003] (1) The floor drain is fixed on the concrete floor and cannot be taken out for cleaning, which has its own hygiene problems and affects the smooth drainage

The floor drain is the interface that discharges the ground water (washing machine drainage, shower drainage) into the pipeline, and is also the interface connecting the indoor space and the drainage pipeline. It plays a very important role in keeping the indoor air quality and the drainage pipeline clean and smooth; In addition to the drainage function, the floor drain also has an important anti-pollution function of forming a water seal to prevent the odor in the drainage pipe from entering the room; the current floor drain is installed and fixed on the ground, and cannot be taken out for cleaning. The self-pollution is serious, and the solid pollution in the floor drain is The water seals gather, and solid particles such as hair and fibers on the surface will drain into the sewer along with the water flow, directly causing pipe blockage and poor drainage.

[0004] (2) The washbasin is directly inserted into the pipeline fixed and embedded in the floor. The accumulated water at the washbasin cannot be discharged nearby. It must be drained into the floor drain through the slope of the bathroom floor building, which is not conducive to the timely discharge of accumulated water, and It will also bring troubles to building design and construction

[0005] (3) The pipeline directly passes through the concrete floor, and the waterproof layer must be turned up to a certain height when encountering the pipeline, which affects the appearance. Moreover, the water on the outer wall of the pipeline will enter the gap between the waterproof layer and the wall along the pipe wall, causing leakage , affects the use; in the current construction process, due to the aesthetic requirements of the bathroom, only a 2 cm high water blocking ring is made, but the effect is very poor, and the bathroom often leaks, causing disputes

[0006] (4) Ordinary single standpipe drainage system has the phenomenon of floor drain back odor, which pollutes the indoor air and affects the health of residents. In order to solve the problem of floor drain back odor and enhance the drainage capacity of the drainage standpipe, the practice of attaching a special ventilation pipe or Increase the pipe diameter of the standpipe. The consequence of doing so is to occupy the indoor area and increase the cost of the drainage system; in foreign countries, there are also methods of using special water-air separation gas to solve the exhaust and drainage capacity of the standpipe, such as Sovent's Transliteration), that is, a special single-standpipe drainage system that combines drainage and ventilation; however, due to the complex structure and large volume, it affects the indoor appearance, and the existing installation leakage problem still cannot be solved
