The Analysis Of Water Supply And Sewerage Design Projects Of High-Building

All of water supply, hot water, fire water and sewerage in water & sewerage design of high-building have a range desire of water head to each of water position or whole system. How to solve those water head questions of according with range is a difficult point and key. The paper analysises detailedly supplying water mode of frequency conversion pump and water valve of high-building's water supply in order to add or reduce water head;air adding press tank system are concretely bought to bear in fire water system;equal water head is adopted in hot water system in order to solve water supply and hot water's balance;all kinds of ventilating erection pipes are synthetically exerted in sewerage in order to solve minus water head rising and sewerage blocking.The last chapter applies some high-building's design example in shanghai to explain application in practice in different system's solving ways about water head in high-building water supply & sewerage, and analyse and calculate in particular water sypply, fire water and sewerage of high building, accordingly it gives readers a more integrated thought and figure in sensibility in water supply and sewerage design of high-building.
