Unifies the actual situation, according to the building nature, the use, is equipped with the consummation with the room in for the water draining water sanitary equipment, concrete gives the drainage system design to be as follows: Water supply system: This basement pump room, building water supply with high, medium and low three divisions, the basement area by municipal pipe work to 7 storeys to low water supply, 8 to 19 stories for the Central, 20 to32 storeys high, high adoption of variable frequency speed governing pump in water supply. Since more than ten fire hydrants, needed two service pipe. Fed from different directions. Ensure the safety of water supply, and to save energy. Drainage systems: Design of sewage wastewater emission system of triage, set aside special ventilation tube, a separate drainage layer. Pipe PVCu pipe. In the basement, before the pump house which houses three sump pit and waste water lifting device. Fire protection system: The buildings 39。 fire protection class belongs to the risk grade ⅰ , designs include fire hydrant system and automatic sprinkler systems. Water tanks on the roof which consists of experiments with fire hydrant installation, ring of fire hydrant water supply pipe work arrangement, the fire box fire pump starts the button inside, can I directly start the fire pump。 the outdoor set of ground water pump bination to ensure fire safety and reliable. Basement, a layer of shops located closetype automatic spray systems. Risers in each system within the well established or laid along the wall, horizontal tube according to the characteristics of the system provides i。
