Abstract:Design the design for the Xuzhou District IKEA courtyard building water supply and drainage engineering. Xuzhou Quanshan area suitable for a family of 21 layers of civil building, two floor underground are storage room and garage, land for residential. In addition, the roof with attic. The basement of each layer is 2.7m, and the top layer is 3.1m, the rest of each storey is 2.9m, the total height is 64m.
The design mainly includes the construction of water supply and drainage of buildings and design, complete with indoor and outdoor part of water supply and drainage engineering including: indoor water supply system, hot water system, fire system, automatic sprinkler system, drainage system and building drainage system.
In the design of water supply system, using the water way. 1 - 3 layer to the bottom, 4 - 15 for the middle, 16 - 21 layer is tall. Bottom, the outdoor water supply in high-rise official website directly, a water pump is adopted, and the tank joint water supply and down to the water supply, water supply reliability, energy saving.
The building is a high-rise residential buildings, according to the code for fire protection of high-rise buildings, fire hydrant should be placed in prominent, often have access and convenient place, so the building room corridor, there is a fire hydrant elevator lobby and uniformly distributed in the basement. The roof tank fire water storage of 10min at the initial stage of fire. The building risk rating for the dangerous level Ⅰ, using wet automatic fire-extinguishing sprinkler system.
In the design of the drainage system, toilet using sewage, waste water diversion system, with separate toilet kitchen wastewater discharge, wastewater is treated in the septic tank is discharged into the municipal sewer, kitchen and toilet wastewater directly discharged into the municipal sewer system. The rain with internal drainage system, rain rain rain set special riser pipe in municipal into.
Hot water system adopts system of full circulation, low area high are layout to the uplink. The most unfavorable point temperature is about 60 ℃, the pipeline temperature between 60 ℃ - 70 ℃. Building hot water system adopts the circulating water pump water supply system, centralized hot water supply, heat from the municipal HTM pipeline (0.20MPa).
