文档编号:GP018   文档字数:16700,页数:66  附CAD图

摘要
 
 本建筑为杭州某16层办公楼，地点位于杭州市：一类高层建筑， 地下一层，地上16层。建筑面积: 30000平方米，其中地下部分面积:1722平方米,地上部分面积:28278平方米. 建筑总高度62.3m。
 给水系统采用分区给水的方式：地下一层到地上三层由市政管网直供；四到十层为中区；十一到十六层为高区；中区和高区均由变频泵加压供水。
 消防系统分为消火栓系统和自喷系统。消火栓系统不分区，采用水箱和水泵联合供水的临时高压给水系统。自喷采用湿式自动喷水系统，地下一层至地上六层喷头由立管ZPL-1供水，七层至十二层由立管ZPL-2供水，十三层至十六层由立管ZPL-3供水。火灾初期10min的水由水箱供给，正常供水由消防水泵从贮水池内抽取。
热水系统的分区与冷水系统保持一致，水加热器集中设置在地下一层。
 排水系统采用污水和废水分流制排水系统，生活废污水直接排入市政排水管网，生活污水经化粪池局部处理后再排入市政排水管网。
 屋面雨水排水系统采用天沟外排水于内落水结合，雨水直接排向市政污水管网。
 各系统均采用设计秒流量来确定管径，依照建筑给排水设计规范来进行管道布置和敷设。

 A 16-STOREY OFFICE BUILDING TO THE DRAINAGE DESIGN IN HANGZHOU
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
