At the same time, in order to meet the fire rescue, around the commercial street set four outdoor fire hydrant, is located adjacent to the residential and commercial street in the middle of the road, are on the ground hydrant; and in the vicinity of 5m set 4 fire pump adapters, to supplement buildings for fire extinguishing water, setting on the ground. The design of indoor fire hydrant water for 40L/s, design of 9 water supply pipe, water gun nozzle selection of 19mm fire gun. Therefore, the choice of fire pump XBD5.5/45-125L, flow rate is 45L/s, head of 55mH2O, speed is 2900r/min, power is 37kw, the efficiency is 73%. In the underground next to garage, there is a 250m3 fire pool, indoor fire water are taken from the pool. In addition, the "spray rules" in the total construction area of more than 5000m2 and shopping malls, risk grade is two. System design flow is 1558.11L/min, bottom water pressure is 0.30815MPa. Selection model for the XBD3.2/40-125ISG spray pump, flow rate of 40L/s, the working pressure is 0.32MPa, the speed is 2900r/min, the power is 22kw, the efficiency is 76%.
Now in order to effectively monitoring the construction of the situation, timely warning signs of fire, the entire building design a set of control center alarm system, setting in a layer of fire room. According to the regulation, the building is a protected object, each layer as a separate alarm area; detection zone in a separate room partition, staircases, corridors, lobby can be respectively pided for the detection of single region. In the detection area, the smoke type fire detector is selected, and at least 1 manual alarm buttons are arranged in each alarm area. In the event of fire, the fire control room is responsible for building fire control and fire control.
