The design task is to design a building, a total of 32 layers, pided thirty level on the ground, two underground floors, a staircase to two high-rise residential buildings. Sanshiyiting household is a kitchen and two baths. Storey building: storey 3 meters, building a total height of 95.8 meters. Each construction area of 392.69 square meters. Water from an outdoor tap ring, water pressure is 0.28Mpa. Architectural design needs for water supply system, drainage system, water supply and hydrant system, automatic sprinkler system and drainage system.

Water way to high-rise building water supply system are: water supply juxtaposed manner, the series water way, way water tank pressure relief valve water way, no way water tank. In these programs, the selection of the way without tank water as the final solution. No water tank manner consistent with the requirements of high quality people, features: no high water tank, to ensure the system pressure constant, according to water changes, the use of frequency conversion device to automatically change the pump speed, and often at a higher efficiency of the pump working. Disadvantages: frequency equipment is relatively expensive, maintenance complex, a power failure is without water. High-rise building water supply zoning should be implemented, it will be the area into the municipal water supply pipe network area 1-4, 5-13 low zone layer, the layer region 14-22, 23-30 layer high zone. This partitioning method can effectively reduce the water hammer in the pipeline, pipeline protection, water and other pipe components, increasing service life and reducing maintenance costs.

Combined with the drainage system is pided into separate system. The design selected for the shunt production design, to ensure maximum safety of the use of the pipeline, to ensure a good indoor environment. Drainage system is pided into single stack drainage system, drainage system and dual riser pipe drainage system Sanli. Toilet choose three depending on design requirements riser drainage system, a special snorkel and sewage and waste water standpipe riser compartment phase, after projecting roof 30cm; kitchen use a single riser drainage system, stretching top snorkel projecting 30-storey roof 30cm.

Fire Hydrant System in accordance with the different fire water pressure can be pided into high-pressure fire hydrant water supply system, stable high-pressure water supply system and temporary high-pressure water supply system. Final selection of temporary high-pressure water supply system as the final solution. Temporary high-pressure system, there are two cases: one case, the usual water supply network can not meet the water pressure and the most unfavorable point, when a fire occurs, the need to open fire booster pump, to fire requirements; another case, the water supply pipe network consists of pressurized equipment to ensure there is enough water pressure within the pipe network, when the fire broke out, fire pump start, to meet the needs of the fire water pressure. One or more layers of the building by the fire water tanks, basement fire hydrant water supply system from the municipal water supply pipe network. Features: the need for complete and reliable supply system.

Automatic sprinkler system is pided into wet automatic sprinkler system, dry automatic sprinkler system, pre-action sprinkler system, deluge sprinkler system and water curtain system. Depending on the condition of the building, the selection of wet automatic sprinkler system as an automatic sprinkler system solutions. Nozzles in a normally closed. Pipe filled with water.When fire happen, fire sprinklers turn the temperature up to temperature of the sprinkler head. Sprinklers head Start spray.Features: Fire timely and efficient for the building of 4 ℃ ~ 70 ℃. Because the system covers almost the entire area, we are able to quickly extinguish the fire in a timely manner. Therefore, in the basement of the building using an automatic sprinkler system and fire hydrant water supply water supply system in combination. 32层一梯两户高层住宅的给排水设计+CAD图纸(2):http://www.751com.cn/gongcheng/lunwen_62813.html
