Safety evacuation exit mainly accounting number, width, distance of evacuation and evacuation stair whether meet the requirements, the stadium security exit set using the bank of China, a security exit of 50, the number of each security exit width is 3m, interval is 16m, the first layer of the width of the evacuation door is 1.8 m, stair adopt outdoor stairwells, stadium stairs width is 2.5 m, the stadium of stair width is 9 m.
Smoke control design is mainly to adopt the mechanical smoke exhaust situation, design A suitable mechanical smoke extraction mode, choose appropriate amount of smoke, the stadium 10 smoke partitions, pided into A zone of 8 smoke partitions, pided into area B A smoke partitions, A smoke area C partition, A total of 6 set of exhaust fan, exhaust smoke volume of 22380 m3 / h, respectively 31680 m3 / h, 19200 m3 / h, 27600 m3 / h, 16080 m3 / h, 16800 m3 / h, choose 5 fire smoke exhaust fan GYF8-1 and 1 GYF10-1 fire smoke exhaust fan.
Fire hydrant water supply system design mainly include indoor and outdoor fire hydrant fire hydrant system. For outdoor fire hydrant needs to determine the number of outdoor fire hydrant and water consumption, for indoor fire hydrant system, fire hydrant was used in the design of 65mm, 19mm nozzle spray nozzle, the diameter of 65mm length is 25m line glue tape. Fill water column length is 13 m, system flow rate of 32.75L/s, the system pressure is 0.3685 MPa, choose three pump adapter, the pump adapter model for SQB100-A model, are set in A, B and D area, the nominal diameter of DN100, nominal pressure 1.6 MPa, the inlet in the form of A button, 65 x 65 mm diameter.
Wet sprinkler system is used in the automatic sprinkler system. According to the specification, determine its belong to the dangerous level of Ⅰ level risk rating. The most unfavorable point of this design flow rate of 0.986 L/s, outlet pressure is 0.055 MPa, the total flow of 26 L/s, the total head loss is 0.5678 MPa, so need to set the pump to pressurize, pump models for XBD6/3-100, speed 2900 r/min, the power of 30 kw.
Automatic fire alarm system according to the characteristics of the stadium, choose smoke fire detector, and according to the installation space limit curve figure that the distance between the probe and thereby determine placement position, in A stadium in the design of the four regions of the first layer and the area A sandwich smoke detector, A zone and B zone, respectively, set up 115, C zone and B zone set respectively, set up 70 ,the mezzanine area A set up 20.
Risk level for class A fire extinguisher configuration places in the dangerous level, each set point matching two portable fire extinguishers MF/ABC4, extinguishing level is 2A, distance of 20 m. According to the actual situation of the stadium fire extinguisher, basic and fire hydrant at the same location.
