【摘要】：高层建筑是现代化城市的主要特色。因其人口密集、高度大等特点,导致其配套的建筑给水系统比较复杂,管线长度大且分支多。加上供水系统点多面广,任何一个环节损坏都会不同程度的影响供水水质、水量或水压,严重影响居民的工作和生活。作为城市给水系统末端最后1km,建筑给水系统的主要目的是将城市给水管网或自备水源给水管网的水安全引入到室内。随着城市现代化进程的加快,我国建筑供水事业也在飞速发展,但同时也存在很多安全隐患,国内对建筑给水系统安全评价的研究还很少,所以对给水系统进行安全评价研究迫在眉睫。本文运用系统安全理论,介绍了风险的几个重要概念,引入了对建筑给水系统进行安全评价的方法。本文基于模糊层次分析法对建筑给水系统进行了评价分析,主要研究内容如下:(1)对国内外关于建筑给水系统安全评价文献的分析,掌握了安全评价发展的趋势和最新的研究成果。(2)对多栋建筑内的建筑给水系统进行调查,并结合查阅文献中总结出的结果,将整个供水系统分解成六个方面:使用功能安全、水质安全、环境安全、工艺单元及设备安全、管道安全和操作安全。在此基础上对各个准则层进行分解得到了18个措施层指标,构造出建筑给水系统安全评价指标体系。(3)运用构造出的安全评价模型对实际建筑物内给水系统进行安全评价,确定了影响建筑给水系统运行安全的主要因素为:流量不足、回流和管道结垢,并得出该建筑给水系统所处的风险级别,最后对建筑给水系统在以后设计、使用和管理中提出了合理的防护对策。
[Abstract]:High-rise buildings are the main features of modern cities.Because of its dense population and large height, the supporting building water supply system is complicated, the length of pipeline is large and the branch is many.In addition, the water supply system has a wide range of points, any link damage will affect the quality of water supply, water volume or water pressure, seriously affect the work and life of residents.As the last 1km at the end of the urban water supply system, the main purpose of the building water supply system is to introduce the water safety of the urban water supply network or the self-provided water supply network into the indoor.With the acceleration of urban modernization, the construction water supply in our country is developing rapidly, but at the same time, there are many hidden dangers in safety. The research on the safety evaluation of building water supply system in China is still rare.Therefore, it is urgent to evaluate the safety of water supply system.Based on the fuzzy analytic hierarchy process (AHP), this paper evaluates and analyzes the water supply system of buildings, the main contents of which are as follows: 1) the analysis of the literature on the safety evaluation of the water supply system of buildings at home and abroad.Having mastered the development trend of safety evaluation and the latest research results, the author investigated the water supply system of buildings in many buildings, and combined with the results summarized in the literature, the whole water supply system was decomposed into six aspects: the use of functional safety,Water quality safety, environmental safety, process unit and equipment safety, pipeline safety and operation safety.On this basis, 18 measure layer indexes are obtained by decomposing each criterion layer, and a safety evaluation index system of building water supply system is constructed. The safety evaluation model is used to evaluate the safety of water supply system in real buildings.The main factors influencing the safety of building water supply system are determined as follows: insufficient flow, backflow and pipe fouling, and the risk level of the water supply system of the building is obtained. Finally, the design of the building water supply system in the future is given.Reasonable protection countermeasures are put forward in use and management.
