徐州好得家商城B区建筑给排水设计与探讨(硕士)(论文30000字)
摘 要
近年，我国各大城市的快速扩张，高层建筑也如春笋般一栋栋的拔地而起，地标及高层建筑越来越多，然而高层建筑内部构造和空间的布置越来越复杂、层数的设计越来越多、建筑的高度也越来越高，同时消防设备的局限性和救援的难度大等，所以高层建筑在建筑给水排水设计和消防设计上难度也越来越大。一批新规范的更新及实施，对建筑物的各方面的要求不断提高，对设计人员的自身水平要求也提高，特别是新的消防规范的实施，通过对国内消防给水及消火栓系统研究、设计、制造以及维护的工程实践经验与科研成果总结与归纳，使消防系统更加完善。同时我国在绿色建筑技术和节水节能方面做出更高的要求，《民用建筑绿色设计规范》和《绿色建筑评价标准》的发布与实施，对于新建和改造项目的设计要求最大限度地达到节能、节水、节材、节地以及环保等目标，同时对于可持续发展战略与以人为本理念的实施具有积极意义。本文在研究徐州好得家商城B区的建筑给排水设计的过程中，涉及到的技术有：雨水收集及循环利用，<<消防给水及消火栓系统技术规范>> GB50974-2014中消防水池的水位控制及增压泵的起泵压力计算等。
通过对本工程的设计和深入的研究，对好的家商贸城进行了个系统详细的过程设计和深入的探讨。主要的内容包括个每个独立系统的施工图的详细设计和计算。施工图的各个系统包括生活和消防的给水、排水等的平面图和系统图；计算主要包括生活和消防的给水、排水等的水力计算；本次设进一步对雨水收集系统，节水节能的一些措施进行了初步探讨，可以看出雨水收集系统是节水节能的一种重要技术手段。最后研究了消防水池的最低有效水位的控制与稳压泵的起泵压力的计算研究，通过对于现阶段几种水池水位争议的分析，我认为泵房的标高降板比消防水池的标高低1米。这样可以减少水池的无效水位，减少水池占地面积。这种做法比较合理。通过新老规范的对比的方法对稳压泵起泵压力的分析，稳压泵的设计压力的值由消防系统最低工作压力(P1)为准计算所得的P2值,也可以由压力开关处的最高工工作压值≥稳压泵水源位置与系统最不利点水灭火设施的标高差(△H)+0.15MPa计算而来。

Abstract
In recent years, the rapid expansion of cities in our country, high-rise buildings and explosion going, landmarks, and more and more high-rise buildings, however, internal structure and layout of the space is more and more high-rise buildings more and more complex, the number of layer design, building height is becoming more and more high, at the same time, the limitation of the fire fighting equipment and rescue is difficult, so the high-rise buildings in building water supply and drainage and fire fighting design difficulty is becoming more and more big. A batch of new specification update and implementation of the requirement of increasing the various aspects of the building and requirements for the level of design staff is improved, especially the implementation of the new fire code, fire water and fire hydrant system research in China are summarized, the manufacture, design and maintenance and management of scientific research and engineering practice experience, make the fire protection system will be improved. In green building technology and water saving and energy saving in our country at the same time make a higher request, the green design of civil buildings "and" green building evaluation standard "launch and implementation, for new and renovation project design requirements to the greatest extent to achieve energy saving, water saving, material saving, land and environmental protection objectives, at the same time for the sustainable development strategy and the implementation of the people-oriented idea has a positive meaning. The main technologies of this study include: rainwater collection and recycling, full-flow high-efficiency variable frequency regulation and water supply technology, secondary water supply front technology, etc.
Through the design and in-depth study of this project, a systematic detailed process design and in-depth exploration of the good domestic business city is carried out. The main content includes detailed design and calculation of the construction drawings of each independent system. The various systems of the construction drawing include floor plan and system diagram of water supply and drainage of life and fire. The calculation mainly includes water supply, drainage and other hydraulic calculation of life and fire fighting. In this paper, some measures of rainwater collecting system and water-saving energy saving are discussed in this paper. It can be seen that rainwater collection system is an important technical means for saving energy and saving energy. Finally studied the minimum effective fire-fighting pool water level control and voltage stabilizing pump of pump pressure computing research, through for the present analysis of several kinds of pool water dispute, I think the pump elevation drop plate is lower than the elevation of fire pool 1 meter. This can reduce the water level of the pool and reduce the area of the sink. This is more reasonable. By new and old specification comparison method of analysis of voltage stabilizing pump up the pump pressure, the design of the voltage stabilizing pump pressure value by the fire control system were calculated using the minimum working pressure (P1) shall prevail P2 value, can also by the pressure switch in high work pressure value of the voltage or the most unfavorable position and system of water pump water fire extinguishing facilities of the elevation difference (delta H) + 0.15 MPa calculation.
Key words: water supply and drainage design of high-rise buildings, water saving and energy saving, rainwater collection and recycling, pump pressure of pump room and water level and steady pressure pump.
