Abstract:The building for the commercial and residential buildings, building height of 80.6 meters. All the buildings are carried at high-rise building water supply and drainage and drainage requirements for the design. Combined with the actual situation, according to the nature of the building, use, and indoor sanitation has improved water supply and drainage facilities, the specific design of the drainage system as follows:
Water supply system:
The building adopts regional water supply, a total of three areas.Six for the ground floor to the lower zone, seven to 16 layers for the Central District, seventeen to twenty five-story high-rise. Respectively by two high pump water supply, set two inlet tube, introduced from different directions, both to protect the safety of water supply, but also saves energy.
The design uses a confluence of waste and sewage discharge system. Drain pipe with UPVC pipes and fittings, using adhesive, pressure pipes welded steel pipe. The septic tank effluent discharged into the municipal sewage treatment pipe network.
The design uses a Fire Hydrant System. Indoor Fire Hydrant System uses high-pressure water supply temporarily, by the fire pond, pressure pumps, water pipes, valves, fire hydrant and other components. Equipped with water tanks on the roof with a fire hydrant experimental apparatus, fire hydrant annular arrangement, the fire box equipped with push-button start fire pumps, fire pumps can be started directly; initial fire from the roof of a 10-minute fire water tank water supply, the normal water storage tanks by a fire pump extracted from. Underground water pump chamber peripheral devices, to ensure fire safety.
Hot water system:
According to the design information, the design must supply hot water for 1-25 layers. To ensure the same point in the cold water, hot water pressure balance, piping hot water pipes along the water, the use of closed mechanical circulatory hot water system.
Each system riser tube wells located within or along the wall in the laying, horizontal tube according to the characteristics of each system for surface or concealed.
The design of the economy, environmental protection, energy conservation principle, by drawing on the previous design methods and experience, using reasonable technical measures to make the design of the various systems used to achieve good results.
