Qian Long Thanh Building 1, high-rise building water supply and drainage design

Abstract:The construction of residential buildings, fire resistance rating of 2, building height of 53.1m, includes a range of domestic water supply system, drainage system, rainwater drainage systems and fire protection engineering design. Domestic water, fire water supply for the city water are water. All the way from the city water pipe is introduced into the pipe DN250, form a ring network in the district, provide municipal water pressure is 0.28MPa. Water Water use zoning, layer 1 to 5 layers of municipal pipe network water supply area, 6 to 11 layers in the layer region by pressurized water supply equipment, water supply; 12 layers to 18 layers of high zone, the pressurized water supply equipment. The building with three risers drainage system. Building one or two layers of commercial outlets, set up automatic sprinklers. Early fire hydrant water supply system from the tank, the late supply by pressurized water is pumped into the basement of a high region.

Keywords:Water Partition;Pump pressure;Fire water tank
