摘要:随着人民生活质量的提高，对于供水量和质的要求不断的扩展，同时实施水的可持续利用和保护，使水资源不受破坏，并能进入良性的水质，水量再生循环，也已成为政府和广大人民群众关注的焦点；同时随着我国社会经济的不断发展，城市化水平的逐步提高，保护环境措施的落实以及市场经济的建立，给水排水事业作为城市的重要基础设施之一，也得到了蓬勃的发展，具有综合功能的大批高层建筑物拔地而起。这一切都给建筑给水排水工程的设计提出了许多新的要求，供水技术先进化的步伐亟待加快。

　　　毕业设计是本科生教学环节中重要的一环，通过毕业设计，可以把所学习的理论知识进行系统地实践，培养我们综合分析问题和解决问题的能力，为今后的实际工作奠定必要的基础，同时把书本上学到的知识系统化。从这个意义上说，毕业设计是我们在大学期间最接近工程实践的一次训练，通过它我们可以掌握工程中的一般思想，计算方法和设计技巧，为今后的实际工作奠定良好的基础。

　　　由于以后我想做建筑行业，所以我选的毕业设计是建筑给排水工程设计，设计的是徐州市经济开发区软件园人才公寓E2楼建筑给水排水工程，该建筑为13层钢砼框架结构，包括一层地下室，一层大厅和若干层住宅。建筑给水跟排水选用PP—R管和UPVC管，消防跟热水用镀锌钢管。

　　　设计的内容包括建筑给水、排水、热水、消防系统，具体包括：初步确定给水、排水、热水、消防管网的布置方式；布置各层给水、排水、热水、消防管道；绘制给水、排水、热水、消防管网的计算简图，并列表进行计算；根据计算结果，最终确定给水、排水、热水、消防管网的布置方式。通过认真阅读规范、设计手册等相关资料以及在老师和同学的帮助下认真完成了这次毕业设计的任务，为以后的工作打下基础。

Abstract:With the improvement of people's living quality, the requirements for water supply and continue to spread, and implement sustainable use of water and protection, water resources are not destroyed, and can enter benign water quality, water recycling, has also become the government and the focus of the masses; Also with China's economic and social development, the level of urbanization gradually improve the implementation of environmental protection measures, and market economy, the establishment of the water and wastewater industry as one of the important infrastructure city, also getting the development, has vigorously comprehensive function of high-rise buildings have sprung up. All this to the design of architectural water drainage project put forward a lot of new requirements, water technologies to be accelerating the pace of advanced.

　　　Graduation design is an undergraduate teaching link, the important one link in the graduation design, can put through learning theory knowledge systematically practice, cultivate our integrated the ability to analyze and solve problems, the actual work for the future lay the necessary foundation, at the same time goes to school the books to knowledge systematized. In this sense, the university graduation design is our closest to engineering practice during a training, through which we can control the engineering of thought in general, the calculation and design skills, the actual work for the future lay a good foundation.

　　　Because I want to do after construction industry,so I choose graduation design is building water supply and drainage engineering design,the design of Xuzhou Economic Development Zone Software Park talent apartment Building E2 Building water supply and drainage engineering design,including a layer of basement, a layer of club and some residences. Building water supply and drainage selection with hot water, fire UPVC pipes and PP—R pipes with galvanization steel tube.

　　　This is preliminary design of the water supply systems, drainage systems, hot water systems and fire fighting systems, including: layout of the bathroom sanitary ware; initially identified water supply, drainage, hot water, fire fighting pipe network layout; arranged layers of water supply, drainage, hot water, fire fighting pipeline; drawing water supply, drainage, hot water, fire fighting control network of the calculation diagram, and the list is calculated; According to the results, and ultimately determine the water supply, drainage, hot water, fire fighting pipe network layout.Through careful reading specifications, design manuals, etc in first shut material and teacher and classmates help seriously finishing the task of graduation design, the work to lay the foundation for the future.
