娱乐中心给排水设计+CAD图纸(3)
Automatic sprinkler fire extinguishing system adopted wet automatic sprinkler system, the system putted out the fire in time, saved the advantages of high efficiency. Applied to the environment temperature was not lower than 4 ° C, and was not higher than 70 ° C. The system alarm valve group setted in a layer of water pump room; Spray water from fire pool directly extracted by spray pump, a rooftop water tank outside setted pump combination. The volume of the roof water tank was 18 ㎡.
This building used the MF/ABC5 mobile (Ammonium phosphate) ammonium phosphate dry powder fire extinguishers. 1 layer to 2 layer setted 3 tools; The rest setted 2 tools. The total number of the fire extinguisher was18.
4) Drainage system:
Living sewage, wastewater used the confluence system, the life sewage, waste water was collected back through the municipal sewage pipe. The special-purpose ventilation tube should be setted in this design . Rainwater system used gutter drainage way, by pooling the back into the municipal rainwater pipe network, didn't confluence with sewage, to avoid increasing the capacity of sewage.
Sludge wastewater and vent pipe used UPVC drainage pipe,.The adhesive connection. "De" in diameter. Rain water drainage pipes adopted HDPE pipes. The adhesive connection. "De" in diameter. The advantages of UPVC pipe are: light weight, easy to shipment; Product with excellent acid and alkali resistance, corrosion resistance, long life; Flow resistance small, the pipe inner surface was smooth, high water capacity; Mechanical strength, resistance to water pressure strength, compressive strength, impact strength was good; with not affecting the water quality, didn't cause secondary pollution; Construction was simple, easy to maintain. HDPE pipe has the advantage : high water security , the orifice was not easy to jam, to ensure smooth system; strong Corrosion resistance and Compressive strength; maintenance cost low,and easy to management.
5) Energy saving:
Without affecting the normal use of sanitary ware in the case we should adopt energy-saving new sanitary ware, which can greatly reduce equipment load, reduce the energy consumption.
Water reuse can be used in the design to increase quality life wastewater reuse rate. Technology refers to the district residents living waste water (sewage) (bath, toilet, laundry, kitchen, toilet) centralized processing, reach a certain standard back for the village road virescence water, car wash, rinse, family sit implement flushing, etc., so as to achieve the purpose of saving water.
Keywords: water supply, drainage systems, fire systems, energy saving
