本科毕业设计 摘要 摘要

本设计是关于嵊州市某宾馆给水排水系统设计，其设计系统包括建筑内部给水系统、建筑内部排水系统、建筑消防系统和建筑雨水排水系统。

建筑内用水设备主要集中在卫生间，卫生间的类型共有6种。给水系统的设计方案采用气压给水方式。排水系统采用的污废合流制排水，管材采用了具有消声功能的螺旋UPVC排水管，为此可进一步提高环境质量。建筑消防系统包括消火栓给水系统和自动喷淋灭火系统，给水系统由室外水箱气压给水。火灾初期10分钟的水由消防水箱供给，正常供水由消防水泵从地下室贮水池内抽取。雨水系统采用的是普通外排水，直接将雨水排向市政污水管网。

设计过程进行了各系统方案的确定、平面布置和计算,以及各种设备的选型。最后用CAD绘制了各个系统的平面施工图和系统轴侧图。 [关键字] 给水系统；排水系统；消防系统；雨水系统

本科毕业设计 摘要 Water system design of a hotel in Sheng Zhou

[Abstract]This design is about the water supply and drainage design of one hotel in Shengzhou

City including interior water supply system, interior water drainage system, fire protection system and storm sewer system of buildings.

The interior water treatment equipments of buildings are mainly concentrated on the toilets which have 6 types altogether. The design project of water supply system uses pneumatic water supply units and water drainage system uses sewage, waste water confluence system. We adopt UPVC spin pipes with noise reduction function so as to further improve environmental quality. The building fire protection system include hydrant water supply system and automatic spraying system. The water supply system get pneumatic water supply by outdoor water tanks. Fire water tanks supply water at the initial 10 minutes stage of tunnel fire and the normal water supply is through pumping the basement reservoir water by fire pump. The rainwater system makes use of normal effluent wastewater to pour rainwater directly into municipal sewage network.

The settlement, plane layout and calculation of different system projects are made in the project process including the type selection of different equipments. At last I finished the plane construction drawings and system axonometric drawings with CAD.
