Abstract:The graduation design topic for building water supply and drainage engineering building of Nantong Municipal Bureau of Commerce design. The comprehensive building of Nantong Municipal Bureau of Commerce, is a comprehensive civil building 14 layer, three layer below for commercial buildings, four storeys for residential. City Road East and south side of the building, there is a municipal water supply pipe can be used as the building water; its diameter is DN300, all the year round the head of 18 meters, and the building of a distance of 20 meters, the top of the pipe buried depth is 1.5 meters. City drainage pipe in the building on the north side, the diameter is DN400, the top of the pipe depth is 2.5 meters, and the building of a distance of 20 meters. Building near the gauge pressure of steam heat source 0.20MPa. Building water supply and drainage system mainly includes the building water supply, building water supply and drainage, fire water and hot water supply of four aspects, first using the data collection analysis classification method and system method to research the building water supply, drainage, fire, hot water four parts present situation and the existence question, proposed the development direction of concrete, second use case analysis research method background the design based on the selected scheme, one by one calculation. Draw a plan, according to the calculation results of the system. This design uses the partition of water, one to three layers for the municipal water supply pipe network directly, four to fourteen layers of the water tank joint water supply.
