The building lies in Changchun city, Jilin provice, which is an integrated highrise structure that acpanies with guest house, meal and drinking, bathing, and so on. The building is about 87 meters high, which is 31,059 square meters area. Its main floor is 21th layers, and the both sides are six layers, but also there are two layers underground. According to design data and request, water supply system is used shunt pump and zoning. There are three partitions: high zone (14th layer to 19th layer), mid zone (7th layer to 13th layer), low zone (underground layer to 6th layer). Based on the characteristic of the structure, there are five manners as following in the drainage system of the project: First, single standpipe drainage system. Second, public kitchen and toilet effluent is designed the independent drainage system. Third, kitchen wastewater is designed theindependent system, and centrially removed oil before it is discharged. Four, collecting sump is located in the underground fire elevator shoot, pumping room, fire control, bathing and so on, and the drain water is discharged by submerged pump. Five, the wastwater of guest room toilet is discharged after being collected in the equipment room (technique interlayer). Fire system and living water system are dividually set up. Fire cock system and automatic spraying system are monly designed. The layout manners of fire cock system are as following: the arrangement of high area and low area guarantees well flowing of three strands inlet (pump inlet, pump adapter inlet, 市 政 與 環(huán) 境 工 程 系 MUNICIPAL AND ENVIRONMENTAL ENGINEERING DEPARTMENT III water tank inlet). High area and low area are used a pipeline by the water block supply, the between of which is installed reducing pressure valve that assures the pressure of the low area. The layout manners of automatic spraying system are as following: the high area (10th layer to 19th layer) is installed two wet alarm valves, and low area (undergroud 1th layer to 9th layer) is installed three wet alarm valves. They guarantee well flowing of three strands inlet the same as they assure the troublefree operation of all inlet water before the warning valves are started. Accoding to the design, I not only am proficient in the design points and the design contents of high buildings’ water supply project, drainage project, fire fight project and so on, but also there is better the basic skill to the engineering drawing.
