Content introduction Design scope: 1. Design of indoor domestic water supply, drainage, fire protection and fire extinguisher configuration of the network; 2. Design of indoor domestic water supply, drainage, fire protection and fire extinguisher configuration; 3. Water supply, drainage, fire fighting and spraying design of basement, domestic water pump room and fire pump room; 4. Design of water spray fire extinguishing system in generator room. Design content: (I) Domestic water supply system: 1. Domestic water supply is divided according to the height, use nature and function of the building; High area water supply is 29~20 floors;, The water supply in the central area is 19~10 floors;, The residence and basement below the 9th floor are low areas. 2. The water supply for this project is supplied by the new underground domestic water tank and water pump room in Block B; Microcomputer frequency conversion control constant pressure water supply. 3. Three self filling domestic water pumps (two for use and one for standby) are respectively set in the high, middle and low areas of the domestic water supply system in the domestic water pump room. After being pressurized, their outlet pipes are connected with the domestic water supply pipe network in the park to meet the requirements of domestic water in the park. 4. The main water supply pipe of the building is laid in the basement and pipe well to supply domestic water for high, medium and low areas. (2) Fire water supply system: 1. The fire water supply of the project is supplied by the new underground fire pool and pump house of Block A; Indoor fire water volume in the park: 20.0L/S; Outdoor fire water volume: 15.0L/S; Spraying water volume: 28.0L/S; Water spray volume: 20.0 L/S Fire pool volume: 400m; In order to ensure the fire water pressure at the most unfavorable point of each fire protection system in the park; Fire water tank and pressurization facilities are set in the water tank room on the top floor of Block A in the park. The volume of the fire water tank is 18m; The fire control center, pipe network, fire fighting facilities, fire water volume and water pressure in the park meet the water requirements of the building. 2. The building is equipped with a fire water supply system, and the fire water volume is 20L/S; The fire water supply is supplied by the fire pipe network in the park; 3. The fire hydrant water supply system in the fire pump room is equipped with two self filling fire pumps (one for use and one for standby). The two outlet pipes are connected with the fire pipe network in the park to meet the requirements of fire water in the park. 4. System setting: The fire hydrant system is not divided vertically, and two sets of fire pump adapters are set. (3) Automatic spraying system: 1. Automatic spraying water supply system is set for equipment rooms such as the underground heat exchange station of the building. It is set according to the medium danger level I; Water volume: 23.0 L/S; One set of alarm valve group is set in the water pump room in the basement. 2. The fire sprinkler water supply system is equipped with two self filling fire pumps (one for use and one for standby). The two outlet pipes are connected with the fire sprinkler pipe network to meet the requirements for fire sprinkler water in the park. 3. System setting: The fire sprinkler system is not divided vertically. The fire sprinkler system of this building is equipped with two sets of fire pump adapters. 4. The basement of this spraying system is equipped with vertical sprinklers; Test valve and pressure gauge are set at the end of the system. The sprinkler adopts 68 ° C. (4) Fire extinguisher setting: 1. Put 2XMF/ABC3 (4 groups) ammonium phosphate dry powder fire extinguishers in the fire extinguisher box in the staircase on each floor of the residence; Set according to light danger level. The operating temperature range is - 20 °~55 °. 2. Put 2XMF/ABC3 (4 groups) ammonium phosphate dry powder fire extinguishers in the fire extinguisher box in the basement; Set according to light and medium risk level. The operating temperature range is - 20 °~55 °. 3. Put 2XMF/ABC3 (2 groups) ammonium phosphate dry powder fire extinguishers in the fire extinguisher boxes on the first and second floors of each network; Press medium danger and setting. 5°~55°。 (5) Water spray fire extinguishing system: a water spray fire extinguishing system is set in the generator room in the basement, with a system flow of 17.4L/S; Spray intensity W=20L/min. m, continuous spray time h=0.5h When a fire occurs, the fire detector acts to alarm the fire alarm, and the fire linkage controller starts the solenoid valve. Open the deluge valve, (open the deluge valve manually remotely, open the deluge valve manually on site,) and the pressure switch acts at the same time to send an alarm signal. The fire linkage controller automatically starts the pump to supply water to the system for fire fighting. (6) Drainage: 1. The building adopts the single riser drainage method. The domestic sewage above the second floor is discharged from each drainage riser to the basement and sent to the outdoor inspection well. The residential drainage is discharged separately and discharged to the outdoor inspection well. 2. The drainage of domestic water pump room, fire water pump room, heat exchange station and fire elevator is lifted by submersible sewage pump and discharged to the outdoor inspection well. The drainage pump is equipped with automatic control device. (7) Rainwater system: the roof rainwater is collected by the drain bucket, and then discharged to the outdoor rainwater pipe network through the rainwater pipe.
