摘要
 
 本建筑為杭州某16層辦公樓，地點位于杭州市：一類高層建筑， 地下一層，地上16層。建筑面積: 30000平方米，其中地下部分面積:1722平方米,地上部分面積:28278平方米. 建筑總高度62.3m。
 給水系統采用分區給水的方式：地下一層到地上三層由市政管網直供；四到十層為中區；十一到十六層為高區；中區和高區均由變頻泵加壓供水。
 消防系統分為消火栓系統和自噴系統。消火栓系統不分區，采用水箱和水泵聯合供水的臨時高壓給水系統。自噴采用濕式自動噴水系統，地下一層至地上六層噴頭由立管ZPL-1供水，七層至十二層由立管ZPL-2供水，十三層至十六層由立管ZPL-3供水。火災初期10min的水由水箱供給，正常供水由消防水泵從貯水池內抽取。
熱水系統的分區與冷水系統保持一致，水加熱器集中設置在地下一層。
 排水系統采用污水和廢水分流制排水系統，生活廢污水直接排入市政排水管網，生活污水經化糞池局部處理后再排入市政排水管網。
 屋面雨水排水系統采用天溝外排水于內落水結合，雨水直接排向市政污水管網。
 各系統均采用設計秒流量來確定管徑，依照建筑給排水設計規范來進行管道布置和敷設。
 
關鍵詞：給水系統；消防系統；熱水系統；排水系統；雨水系統

ABSTRACT
 
 The construction of a 16-storey office building in HangZhou , located in Hangzhou City: a class of high-rise buildings, underground floor, the ground layer 16. Building Area: 30,000 square meters, including the underground sections of the area: 1722 square meters, part of the ground area: 28,278 square meters. The total construction height of 62.3m. Water district water supply system the way: the ground floor to three direct supply by the municipal pipe network; 4-10 layer for the Central District; 11-16 layer higher areas; in the district by district and high pump pressurized water supply. Fire hydrant system and the system is divided into self-spray system. District fire hydrant system, water tanks and pumps using temporary high-pressure water supply joint water supply system. Since the use of wet-spray sprinkler system, underground floor to the ground by six sprinkler riser ZPL-1 water, formed by seven to 12 risers ZPL-2 water supply, 16-storey by legislation to ZPL-3 water supply pipe. 10min fire early supply of water from water tanks, fire pumps from the normal water storage tanks from the extraction. District water system in line with the cold water system, water heater installed in the ground layer of focus. Drainage system triage system for sewage and waste water drainage systems, waste water directly into the life of the municipal drainage network, domestic sewage treated by septic tanks into the local municipal drainage network. Roof Drainage Gutter outside the drainage system in combination with water, rain water directly discharged to the municipal sewage pipe network. Systems are designed to determine the diameter of seconds traffic, water supply and drainage construction in accordance with design specifications to layout and the laying of pipelines. Key words: water supply system; fire-fighting system; hot water system; drainage system; rainwater systems
