The Study On Security For The Water Supply System Of High-rise Building

With the economic and technological development, high-rise buildings sprang up like mushrooms in major cities. High-rise buildings due to a high degree of large, multi-layered, building area, building function complex, the number of users, activities and risk of large construction equipment and therefore have higher than normal building more stringent requirements. High-rise building construction equipment, water supply system is the most basic, the most important component of, regardless of the depth and breadth of technology, or in the design and construction difficulties, the more than a general building water supply projects. Water quality, water rates and water supply system to ensure the noise generated by people's health are all a great impact on the lives, safety, energy, health, construction of internal water supply system the direction of future development, strengthen the construction of safe water within the water supply system it is necessary to study .Water supply plastic pipe in large numbers, has enriched the architectural design of selected range of water supply pipe. To meet the specifications of the conditions, often there are several pipes to choose from, the advantages and disadvantages of these tubes coexist. Therefore, the pipe option is an issue worth studying. In this paper, fuzzy mathematics of AHP and value of the coefficient to carry out water supply pipe under the specific conditions of choice. Application of fuzzy analytic hierarchy process to fully take into account a variety of factors, first of all the actual characteristics of the works to establish evaluation index system of factors, the various indicators of the program from low level to high-level order, to conduct a comprehensive evaluation to be an established and relatively quantified realistic evaluation results. Value coefficient method is by calculating the functional assessment of a variety of water supply pipe evaluation factor and cost factor, and then find the ratio of two factors, according to the ratio of the size (ie cost effective) to determine the value of water supply pipe, thus singling out any particular project optimum pipe.Water flow rate reflect the indoor water supply pipeline design loads of life, which is to determine the diameter of the pipe water supply basis. Therefore, the study for calculation method of rational design of seconds water flow has important practical significance. This paper analyzes the domestic and international architectural design of seconds water flow calculation methods, based on a continuous normal distribution model to simplify the calculation of discrete binomial distribution, with the De Moivre - Laplace (De Moivre-Laplace) theorem derived based on probability On the architectural design of the internal water flow equation seconds.Finally, this article high-rise analyzes the reasons for the noise from the following three aspects:water pump, piping, water apparatus of building water supply system , and puts forward the specific control measures. The control of noise should consider two aspects of the noise source and transmission and accord with the design and construction specifications strictly, to make the system work by acoustic noise reduction facilities. The integrated control of noise should control from all aspects of the design, construction and management .
