Description

A swirl type same-layer drainage system

technical field

The invention relates to the technical field of building drainage systems, in particular to a cyclone-type same-layer drainage system.

Background technique

For a long time in China, residential buildings have been using traditional partition drainage methods. With the rapid development of the national economy, people no longer simply focus on the function and cost factors, and have higher and higher requirements for the hygiene, design, convenience, comfort and individuality of the house, which puts forward the requirements for the construction of traditional houses. new requirements. In recent years, urban planning departments and architectural design departments have paid more attention to the "people-oriented" design concept, paid more attention to creating and humanized design space, paid more and more attention to people, respected people, and paid more and more attention to people's emotions and culture towards architecture need. In this context, many problems of inter-layer drainage have gradually emerged, which can no longer meet people's requirements for building drainage, and the same-layer drainage came into being.

my country's regulations on residential buildings encourage the same floor drainage method: "Residential Design Code" (GB50096-2011) Article 8.2.8 stipulates that the horizontal sewage and wastewater drainage pipes of residential buildings should be set in this floor; "Building Water Supply and Drainage Design Code" (GB50015-2003 2009 edition) Article 4.3.8 stipulates that the drainage horizontal branch pipes of sanitary appliances should be set with the same layer of drainage under the following circumstances, and Article 4.3.8A stipulates that the drainage form of the same layer of residential bathrooms should be based on the toilet space, sanitary appliance layout, and outdoor environment. Factors such as temperature are determined by technical and economic comparison. Article 4.3.8B stipulates that the drainage design of the same floor shall meet the following requirements; Article 2.7.4 of "Technical Key Points of Healthy House Construction" (2004 Edition) stipulates that the drainage branch pipe shall be bounded by the household. . Some of the terms in the above provisions use "should" and some use "should". But they all express the same concept, the drainage design of residential toilets should use the same floor drainage.

Drainage on the same floor means that the drainage pipes (including horizontal sewage pipes and drainage branches) of sanitary utensils (including kitchens, balconies, etc.) in the bathroom do not pass through the floor of this floor and enter the lower space, but are laid on the same floor as sanitary utensils. The building drainage system connected to the drainage riser on this floor. Compared with the traditional inter-floor drainage treatment method, the most fundamental conceptual change of the same-floor drainage scheme is to completely get rid of the shackles between adjacent floors through the rational layout of the pipes in this floor, and avoid the encroachment of the lower space caused by the horizontal drainage pipes. A series of troubles and hidden dangers, users can personalize the position of toilet sanitary ware according to their own hobbies and wishes.

At present, the same-floor drainage installation method is aimed at the same-floor drainage based on the layout of different toilets, reasonable laying of pipes, and an installation method that achieves effective drainage and sewage standards. From the wall structure installation method, it is divided into four different methods: 1. Descending: that is, the toilet floor (or partial floor) sinks; 2. The wall row (mainly characterized by the pipeline installation system) method; 3. Pad Layer type; ④ not drop the board.

In engineering practice, different same-floor drainage methods have their own characteristics and scope of use. The wall-row type same-floor drainage technology is relatively mature, but it has many drawbacks; while the descending plate-type same-floor drainage is a kind of Chinese-style same-floor drainage. Drainage technology is prone to stagnant water and difficult for maintenance workers; cushion type is only suitable for retrofitting of old interests. The characteristics of the same floor drainage without lowering the board are as follows: (1) The toilet/kitchen/balcony is equipped with a floor drain without lowering the same floor drainage. (2) Improve drainage safety: The water seal is shared by the washbasin, floor drain, shower and other drainage facilities to ensure the long-term effectiveness of the water seal of each drainage device in the system, and the non-return device to slow down the evaporation of the water seal greatly improves the drainage safety. At the same time, it also closes the compartmental transmission of viruses and bacteria. (3) Improve the efficiency of space use: the height of the traditional descending board is large on the same floor, and the net height between floors is small, especially after the installation of electric water heaters, people appear depressed after entering the bathroom, and the drainage space on the same floor without descending board has high use efficiency . (4) Saving building materials and lowering project cost: Compared with the waterproof materials, backfill materials, etc. consumed by traditional descending slab drainage at the same level, the non-slab drainage system greatly reduces the usage of these materials, reduces construction difficulty and project cost, and has The prerequisite for large-scale application in engineering. The same-layer drainage system without falling slab is a cutting-edge drainage system at present, but it also has its limitations. The imperfect products and imperfect standards hinder its popularization and application.

There are the following problems in the existing non-drop-board same-layer drainage system on the market: First, the drainage system adopts a split design, and the sealant or rubber ring at the lap joint will be aged for a long time, resulting in the risk of water leakage; second, the concentrated water With a filter screen or no centralized water seal, there is a risk of transmission of viruses and bacteria in the drainage pipe, and there is a safety risk; third, the sewage in the water trap is directly discharged into the riser, causing large air disturbance in the riser. The large change in the air pressure of the riser can easily damage the water seal of the water trap and reduce the air tightness, which is easy to cause the “unpleasant smell” of the bathroom and the spread of bacteria and viruses. There is a conflict between the pipe size and the thickness of the underlayer on the floor layer.
