Abstract
The main task of this design is the water supply and drainage design of a high-rise hotel in Tianjin. The content of my design includes the design of the building water supply system, the building water drainage system, the building storm-water system, the hydrant water supply system and the automatic sprinkler system.
The building has 1 floor underground and 17 floors overground. The height of the building first to the fourth floor are Non-standard layer; The fifth to the sixteenth are standard layer;The seventeenth is the top.
The municipal water supply piping can provide head. After parison of technicality and economy, interior water supply system intends to adopt subarea water supply. Preliminary study out that building water supply system is divided two areas: 1~6 floors are low area. The work supplies water directly from municipal water supply piping;7~17 floors are high area. Water supply is supplied by no negative pressure water equipment.
The building water sewerage system adopt confluence .All waste water enter drain via a septic- building storm-water system adopts inner draining.
Hydrant water supply system includes interior hydrant water supply system and outside hydrant water 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 28m.
The number of sprinkler heads in the building is about 1954. The automatic sprinkler system set up 3 groups watery alarm valve. Behind the alarm valve, the piping is set as branch. E
