1. Classification
water supply pump room can be divided into domestic water pump room and fire water pump room.
2. Functional composition
water pump room consists of a pump room and an auxiliary room. A living water pool (box) or fire water pool (box) can be attached in the pump room, or it can be set separately.
333. Location selection and separation requirements from other functions
1. Water pump room should not be arranged in rooms with vibration prevention or quiet requirements, above, below or adjacent to residential rooms.
2. The water pump room is strictly prohibited from being arranged above the electrical room. The water tank room on the roof should not be set above the elevator machine room.
3. The domestic water pump room and the domestic water pool (box) should not be located in the same room as the sewage pump room and the recycled water treatment station. There should be no toilet, bathroom, bathroom, bathroom, kitchen, sewage treatment room, etc. above it.
4. fire resistance level and fire protection requirements
1. The fire resistance level of the fire pump room should not be lower than the second level. When set up in other buildings, the fire resistance level requirements of the building should also be met at the same time.
2. The fire water pump room attached to the building should be separated from other parts with a fire resistance limit of no less than 2.0 and a floor slab with a 1.50h fire resistance. It should not be set up on floors with a third floor or below underground floor or a floor height difference between the basement and the outdoor entrance and exit floors should be greater than 10m.
3. Waterproofing measures should be taken in the fire water pump room; when it is installed underground, anti-flooding measures should also be taken.
4. The evacuation door of the fire pump room should lead directly to the outdoor or a safety exit.
5. The evacuation door opened in the fire pump room into the building should be Class A fire door . The evacuation door opened in the building of the domestic water pump room should be a Class B fire door. The design of fire protection facilities such as
6, the pump room's smoke protection, smoke exhaust facilities, fire water supply and fire extinguishing facilities, fire power supply, fire alarm, control systems, etc. shall comply with the relevant professional specifications and the provisions of " Building Design Fire Protection Code " GB50016.
5. Safety, sanitation requirements
1. The body of the daily drinking water pool (box) in the building should adopt an independent structural form, and the main structure of the building shall not be used as the wall panel, bottom plate and top cover of the pool (box).
2. The wall material and lining material of the living water storage tank (box) should be selected. Materials that meet sanitary and safety requirements, have no adverse effects on water quality and are strong and durable.
3, water pump room, water tank floor (floor), interior wall, and ceiling decoration materials should be non-toxic, harmless and easy to clean.
6. Water tank spacing and equipment entrance and exit
1. The clear distance between the outer wall of the low-level water storage pool (box) in the building and the building wall or other pool (box) walls should meet the construction or assembly requirements. On the sides without pipes, the clear distance should not be less than 0.7m; on the sides with pipes, the clear distance should not be less than 1.0m, and the width of the passage between the outer wall of the pipe and the building wall should not be less than 0.6m; Teacher Du of the HVAC Design reminds that the clearance of the top plate surface of the pool with manholes and the bottom of the structural plate should not be less than 0.8m.
2. The net size of the entrance and exit of the water pump room should consider the needs of replacement and handling of the machine parts. A lifting port can also be installed on the roof of the pump room as needed.
7. Ventilation
1. Good ventilation conditions should be provided in the water pump room and the attached domestic water tank.
2. There should be measures to prevent rain, snow and small animals from entering the room from opening windows, ventilation windows and holes.
8. The ground (floor) surface
1. The ground (floor) between the pump room and the water tank should be lower than the ground (floor) surface on the same floor, and drainage facilities such as drainage ditches and collecting pits should be set up. The ground (floor) faces the drainage ditches and find 1% slope. It is advisable to set up a 150-200m high waterproof door threshold at the door.
2. The floor (floor) between the water pump room and the water tank should be waterproofed. When the pipe passes through the exterior walls and floor slabs, waterproof casings or concrete edges should be installed, and waterproof sealing measures should be taken around the pipeline.
9. Insulation and insulation
1. When the indoor temperature between the water pump room and the water tank in the heating area is lower than 5℃, anti-freeze measures should be taken.
2. Water pump rooms in hot and humid areas should be appropriately increased and ventilation, heat insulation and moisture-proof measures should be taken.
3. Anti-freeze measures should be taken for fire protection and living water pools that are independently set up.
10. Vibration isolation, sound insulation, sound absorption
1. Computer room noise control should comply with the national standard " sound environment quality standard " GB3096-2008.
2. Vibration and noise prevention measures should be taken for the foundation and pipelines of the water pump room equipment.
3. Sound absorption structural measures should be taken in the walls and ceiling of the small pump room.
4. The outer door of the water pump room should be a soundproof door.
