The content of my design includes the design of the building water supply system, the building w ater drainage system, the buildi ng stormwater system, the hydrant water supply system and the automatic sprinkler system. The building has 1 floors underground and 14 floors overground. The height of the building is first～ the second floor are used for business. The third floor～ the 14th floor are used as the big space municipal w ater supply piping can provide head. After the parison of technicality and economy, interior w ater supply system intends to a dopt subarea water supply. Preliminary study out that building w ater supply system is divided tw o areas: 1～3 floors are low area. The pipe w ork supplies w ater directly from municipal w ater supply piping。3～ equipment floors are high area. Water supply is supplied by water pump and high water tank . Part of the building sew erage system adopt confluence .All sewage enter drain via a septic tank. The w ast w ater emissions to sewer w ater supply system includes interior hydrant w ater supply system and outside hydrant w ater supply system. Hydrant arranging range includes every storey, the room in front of fire elevator and roof for check. The hydrant protects a radius of number of sprinkler heads in the building is about 2284. The automati c sprinkler system set up 3 groups w atery alarm valve. Behind the alarm valve, the piping is set as branch. Every storey set w ater flow indicator. Keywords： the building water supply system, water drainage system, hydrant water supply system, the sprinkler system 華北水利水電學(xué)院畢業(yè)設(shè)計 目錄 摘要 ..................................................................................................................................................
