Xinhuanet, Beijing, December 5 (Reporter Sun Yubo and Deng Yaping, Xinhua Viewpoint)

Indoor air quality has never touched the hearts of millions of households as it does today, and it has also affected the hearts of national leaders.

From June to September this year, the two deputy premiers of the State Council issued three instructions in a row. They pointed out that the environmental problems in the house are related to the health of the residents and must be given high priority and instructed relevant departments to conduct research. At the same time, relevant ministries and commissions such as the Ministry of Construction, the Ministry of Health, the General Administration of Quality Supervision, Inspection and Quarantine, and the State Environmental Protection Administration are working hard to formulate relevant regulations and standards.

68% of human diseases are related to indoor pollution

In June 1997, an office building in Beijing was attacked by Legionnaires' disease. At one time, 108 people in the building were ill. The prevalence rate was 34.62%. The patient presented with pain in his body, and some people had tonsil inflammation, diarrhea, and high fever. Legionnaires' disease was first discovered in 1976 at a veterans' conference in Philadelphia, USA, and was named after it. Legionnaires' disease is mainly caused by gram-negative bacilli. Legionella pneumophila colonizes and grows in water. It mainly spreads through cooling water in air-conditioning cooling towers, air-conditioning ducts, faucets, and showers. Symptoms are fever, chills, headaches, difficulty breathing, vomiting, diarrhea, etc. Similar to the symptoms of pneumonia. According to reports, there have been 7 cases of Legionnaires' disease in the country. In fact, more than 300 pollutants can be detected in the air, and about 68% of human diseases are related to indoor pollution. Song Guangsheng, director of the China Interior Decoration Association, believes that indoor environmental pollution is mainly caused by improper use of decoration materials. One is that the design is irrational, and the room uses too much of a material, such as large-scale laying composite flooring caused by excessive formaldehyde; Second, the process is irrational, the traditional process did not consider the indoor environment issues, such as composite flooring bunk core board, wall brush Varnish to prevent cracks, the traditional process furniture will not bring the edge of air pollution; the third is to choose inferior decoration materials

In 2003, the SARS event in Hong Kong Tao Da Garden was an unqualified source of trouble. This incident is enough to confirm the importance of the drain.

Edit this paragraph select points

Floor drain

1) The CJ/T 186-2003 standard is only applicable to floor drains used in general industrial and civil buildings. It does not apply to special places such as anti-wave floor drains for civil air defense projects and explosion-proof floor drains for petrochemical enterprises. For floor drain in special places, in addition to the reference to this standard, it should also meet the technical requirements of the relevant industries.

2) Water seal is one of the important features of water seal floor drain. When choosing, you should know whether the water seal depth of the product reaches 50mm.

Sidewall floor drains, floor drains, and enclosed floor drains are generally not water seals; spill-proof floor drains and multi-channel floor drains are mostly water seals, which should be clearly understood when selected.

For water leaks without water seals, drains should be drained at the depth of not less than 50 mm. This part can be configured by a floor drain manufacturer or by a construction unit that has installed a floor drain.

3) The level of the floor drain can be adjusted and the height can be adjusted to not less than 35mm to ensure that the height of the floor drain after the floor decoration is completed is level with the ground. The water-proof wing ring is installed on the floor to ensure that the floor drain is installed in the floor when it is waterproof.

Floor drains located in underground garages or in places where they are subjected to heavy loads should be capable of meeting the corresponding loads.

4) The structure of the floor drain with water seal shall be reasonable and smooth, and the debris in the drainage shall not be easily precipitated; the cross-section area of â€‹â€‹each part should be larger than the cross-sectional area of â€‹â€‹the discharge pipe, and the minimum net width of the flow channel cross-section should not be less than 10mm.

5) There are three types of floor drain connections: sockets; threads; clamps. The size of the connection port can be determined according to the relevant regulations of the current country

6) Priority should be given to deodorizing floor drains. Where there is no need for drainage, floor drain may not be provided. The builders have not set up land drains and they have not set up backwater bays to work.

Floor drain

The floor drain in the area can be set in an inconspicuous place, because there will not be much accumulated water on the ground; in the wet area, for example, in the shower area, in order to ensure the smoothness of the water, not only can it not be hidden, but also it must be lower than about 10 mm above the ground. It may not look good. At this point, you can decorate with some designs. For example, to hide the floor drain and make a hollow metal hollow decoration on it, it can resonate with the indoor effect and also play a role of â€œsecondary filtrationâ€. Alternatively, the ground around the floor drain can be tiled with a curved, sloping pattern that is both beautiful and helps to increase the speed of the water flow.

In addition, you can also make use of the characteristics of the toilet floor being elevated, and make a small â€œpondâ€ with the ground drain as the center.

Edit this section to install

Floor drain

The installation of floor drains is complicated and must be completed by professionals. When installing, please note:

Floor drain

The first is to trim the drainage reserved hole so that it completely coincides with the floor drain that was bought back, because the reserved hole for real estate developers to drain water is relatively large. Among them, the opening diameter of the floor drain rake should be controlled between 6-8mm, which can prevent the entry of hair, sludge, sand and other dirt;

Second: It should be grasped that the intake of multi-channel floor drains should not be too much. Multi-channel floor drains have been developed in recent years. There are usually 3 to 4 inlets in a body (accepting face washers, bathtubs, washing machines, and floor drains). This structure not only affects floor drain displacement, but also does not meet actual design conditions. . Therefore, the intake of multi-channel floor drains should not be excessive, and two (ground and bathtub or floor and washing machine) can fully meet the needs.

Edit the material used in this section of the floor drain

Mainly cast iron, PVC, zinc alloy, ceramics, cast aluminum, stainless steel, brass, copper alloy and other materials.

1. Cast iron: cheap, easy to rust, unsightly, sticky dirt after rust, difficult to clean;

2, PVC: cheap, vulnerable to temperature deformation, scratch resistance and poor impact, not beautiful;

3, zinc alloy: cheap, easy to corrosion;

4, ceramics: cheap, corrosion-resistant, not resistant to shock;

5, cast aluminum: price mid-range, light weight, rough;

6, stainless steel: affordable, beautiful, durable;

7, copper alloy: affordable, use type.

8, brass: heavy quality, high-grade, high prices, the surface can be plated.

Edit this paragraph floor drain - overhaul of the ground drain leakage causes analysis: may be a high degree of water leakage of the floor drain is not easy, easy to dry, causing the odor inside the drainage pipe into the room.

Solution: First, the floor drain does not necessarily have a return bend, and one can be added to it. Second, change the same floor drain with the same brand, the same specifications. However, during construction, be careful not to damage the waterproof layer. In addition, it should be reminded that during use, water seals should be prevented from drying out and regular water injections must be performed. If you leave for a long time, it is best to seal the floor drain with a lid. Ground-drain overflow analysis: It may be that the cross-section of the floor drain is not smooth enough, the sewage cannot pass quickly, or the internal structure of the floor drain protrudes, and dirt such as hair and fibers is caught.

Solution: The height of the floor drain is determined by the way in which the drainage system is routed. Therefore, the floor drain heights that are used in conjunction with them are preferably within 200mm and within 120mm, respectively, and must be drained laterally. The commonly used concealed installation method is that there are two types of toilet floor slabs that are partially submerged and toilets are cushioned. In order to meet the bathroom height and ergonomic requirements, the former's sink clearance is 300mm, the latter's cushion height is the highest 170mm. Water leakage solution: open the floor drain around the floor tile, around the cement to dig 3cm deep, and then use The â€œplugging spiritâ€ was sealed and a water-blocking test was done after 1 hour to see if it was still seepage. If it did not leak, then it means to restore the original status.
