1、. . . . 摘 要长信大厦是为了满足公差旅游、休闲、外出的需要，而为旅客提供住宿、参观、社交、娱乐等多种服务，位于省沅江市繁华地段的一座多功能建筑。建筑面积为12943.9m2, 本建筑最高层为八层，建筑高度为33.50m。该建筑地下一层为车库、配电室、水泵房、设备间等，室地面标高为-3.50m；地上八层，一层为商铺，层高为6.0m；二层为茶艺大厅和包房，层高为5.0m；三层为厨房、包房和餐厅，层高为5.0m；四、五层为客房、会议室、办公室，层高为3.0m；六、七层为客房、会议室，层高为3.0m；八层为多功能大厅和仓库，层高为3.0m；具体布置如工程图纸所示。水源由市政给水管网提供，其常年
2、压力为0.3Mpa。水源由市政给水管网供给，该设计给水系统采用分区供水方式，低区为地下一层至地上三层，高区为四层至八层，高低区均采用水泵水箱联合供水。消防系统采用消火栓灭火系统、自动喷淋灭火系统相结合的方式，消火栓灭火系统管网布置成环状，在建筑外侧设两个水泵接合器，当水量不足时可由室外消防车通过水泵接合器供水。自动喷淋灭火系统采用独立的湿式自动喷水灭火系统，该系统具有灭火与时，效率高的优点，但也存在缺陷，由于管网中充有有压水，当渗漏时会损坏建筑和影响建筑物的使用。该建筑的功能决定采用集中热水供应，由于集中热水供应系统可以集中设置加热和其他设备，便于集中维护管理；加热设备热效率高，热水成本较低；
3、各热水使用场所不必设置加热装置，占用总建筑面积较少；使用较为方便舒适。本设计排水系统采用生活污水和生活废水合流排放，地下室污水采用单独排出，多根排水立管在建筑物顶部共用伸顶通气立管。雨水系统 采用外排水系统，设单斗雨水立管，雨水斗采用87型，材料为塑料。关键词：给水系统；消火栓系统；自动喷淋灭火系统；热水系统；排水系统；雨水系统。AbstractJinTian Building is located in the downtown area of Yuanjiang City,Hunan Province. It is multi-functional, which can provide p
4、assengers with accommodation, sight-seeing, social service, entertainment and other services so as to meet passengers requirements in their business travel, leisure travel and etc. The 33.50-meter high building has 8 floors and it covers 12943.9m2. The first floor underground is used as garage, swit
5、chgear room, water pump room, and equipment room etc. The floor elevation is -3.50m. For the 8 floors above ground, the first floor is shopping mall. The floor height is 6.0m. The second floor is designed as tea rooms and private rooms, 6.0m high. The third floor is used as kitchen, private rooms an
6、d restaurant, 5.0m high. The fourth and the fifth floors are used as guest rooms, meeting rooms and office rooms, 3.0m high. The sixth and the seventh floors are used us guest rooms and meeting rooms, 3.0m high. The eighth floor is multi-functional hall and warehouse, 3.0m. Please see the detailed l
7、ayout as in the engineering drawing. Water is supplied by municipal water supplying network, with yearly average pressure 0.3Mpa. The water supply system is designed as zone water supply. The low zones are from the first floor underground to the third floor above ground. The high zones are from the
8、fourth floor above ground to the eighth floor above ground. Water supply for both the low zones and the high zones are by water pump and water tank. Fire control system adopts the combination of the fire hydrant system andthe automatic spray firefighting system. For the fire hydrant system, the pipe
9、s are set as rings; two water pump adapters are set outside of the building. When there is not enough water, water can be supplied by firefighting trucks through water pump adapters. For the automatic spray firefighting system, independentautomatic wet pipe sprinkler system is adopted. This system c
10、an extinguish fire in time, and is of high efficiency. But there are disadvantages in this system. Since when the confined water in the pipe network leaks, it will affect and damage the building. Because of the functions of the building, centralized hot water supply is adopted. Devices and equipment
11、s can be heated at the same time, which makes maintenance and management easy. The heating equipment is of high efficiency and the cost of hot water is low. Heating devices and equipments do not have to be set where hot water is needed. It can thus save place and make it convenient to use.For the wa
12、ter drainage system, it is designed as combined sewage and waste water discharge. The waster water in the underground floor of the building is discharged separate with water in other floors. For each vertical draining pipe, vent stack is set at the top of the building. For the storm water system, ou
13、tside storm system is adopted. There is single rain strainer, and it is “87” type. The material is plastic.Key words:water supply system, fire hydrant system, automatic spray firefighting system, hot water system, water drainage system, storm water system.目 录摘要IAbstract.II第1章 工程概况11.1设计依据11.2 原始材料11
