For a long time, our residential water meters are located in the indoor kitchen or bathroom water concentration of office. Meter located indoors, not only meter reading workload, but also housing security and privacy greatly reduced. Therefore, the sub-family residential water meter should preferably be located outdoors.
The design, water wells located in water supply pipeline, a water meter box set per household. The advantages are: household branch short, more saving tube; pipeline head loss is also small; full use of tube wells in the public space, do not use the area occupied by tenants; easy to manage and maintain.
4.1.2 Drainage System
Indoor Living sewage combination of wastewater. Bathroom drainage with special ventilation tube riser and riser across the second floor and sewage connections. Kitchen set Stack venting.
Waste water and underground parking with elevator sump pit next to the wastewater submersible sewage pump by upgrading to the outside row, into the outdoor water pipe network.
With sump pump house next to the wastewater by upgrading sewage pump arrangement to the outside, discharged into the outdoor rainwater pipe network.
4.1.3 Hydrant system
Fire service water 10L / S, outdoor fire water 15L / S located on each floor of a residential fire box, fire box equipped with water cannon 2,10-φ65 φ19 a rubber lining hose length 25m 2, φ65 pay hoses Interface 2 , box equipped with a fire pump start button.Temporary high-pressure fire hydrant system is the system, the roof of a fire water tank located 7.5M3.
2 sets of pumping stations located in the basement fire pump (one with a device), a direct suction from the municipal pipe network. Three fire hydrants ~ basement exit orifice of a different set φ19 decompression. Four to six fire hydrants located φ22 all exports of a decompression plate
4.2 tubing materials
Pipeline of comparative economic and technological process is technically from pressure, temperature, use of the environment, consider areas such as installation methods, combined with the requirements of owners and residential grade, after comprehensive consideration of economic techniques to determine. General use of the traditional water pipe galvanized steel pipe, galvanized steel as easily corroded and short service life, used to deliver water can not meet water quality health standards and other shortcomings, the Ministry of Construction are strongly promoting the application of plastic to the water.
(1) water supply: water supply pipeline meter indoor life after the use of PP-R pipe, hot melt connection. Cold water pipe pressure rating 1.6MPa, water pipe pressure rating of 2.0MPa. Meter before the pipeline with steel-plastic composite pipe.
(2) Fire Management: Fire tube with hot dip galvanized steel pipe.
(3) Drain: UPVC drainage pipe used.
(4) through the trachea: use UPVC drainage pipe.
(5) basement buried in the floor drain, pressure pipes are hot-galvanized steel pipe.
4.3 Pipeline and
Laying in the pipe shaft. Bathroom set up centralized pipe wells, drainage wells are concentrated in the pipeline arrangement, which is a well-house kitchen, bathroom residence an important manifestation of civilization. Commercial housing in the Design of high-end bathroom tube wells should be considered in the setting, this would increase the use of quality bathroom, PVC pipes can solve big problems flow noise and improve indoor environmental quality standards.
