1、摘要本设计是商住楼给水排水工程设计，主要包括给水系统、排水系统和消防系统三个部分。本次设计的目的是充分利用所学的现有的知识，完成高层建筑给水排水工程的设计。此次设计基本上实现了我们从理论知识向实际工程设计的转变，充分的把理论知识应用到实际的工程当中，并对设计的方案、内容加以有针对性地、有说服力地论证，从而实现设计工程的可行性。在选题的过程中，考虑到地区性、建筑性质，选用高层建筑，建筑类别相对高级，进行建筑给水排水工程的设计，满足人们的生活需要，并且使人们得到舒适、便利生活环境。设计的大体内容是：建筑给水工程、排水工程、消防工程、雨水工程，设计的意义在于满足人们生活用水的同时，要满足室内的消防用
2、水，保证人们居住的安全性。设计的依据为相关书籍和设计手册、规范。在设计中，严格依据设计手册中的相关规范来进行，建筑给水排水系统及卫生设备要相对完善，在技术上要保持先进的水平，在计算的过程中，尽量使用符合经济流速的管径,以便降低成本，同时要考虑水的漏失、压力情况来选择管材和一些连接管件，以便在水从市政管网输送到建筑内用户的过程中，水的漏失量最少，节约水资源。本次毕业设计根据所提供的建筑物为三十四层的高层住宅楼，地下一层，该层该楼的供水中心（水泵间、锅炉房、变电室、控制室等都在此层），本建筑以城市给水管网作为水源，从市政管网取水，供水水压为0.15MPa。土壤最大冻结深度-1.34m,市政管网不允
3、许直接抽水。设计时结合建筑的性质、用途及建设单位要求， 室内设有完善的给水排水卫生设备。该项目建筑要求消防给水安全可靠，每个消火栓箱的设按钮，消防时直接启动消防泵，在地下室的锅炉间考虑用水雾系统。该建筑为商住楼，建筑高度为101.20米，长27.8米，宽16.8米，共33层，地下1层，地上32层。本建筑物所有给水排水均按高层建筑给排水要求进行设计。结合实际情况，根据建筑物的性质，用途，和室内设有完善的给水排水卫生设备，具体的给排水系统设计如下：给水系统：本建筑地下一层至地上七层由室外市政管网直接供水，八至二十层设有变频调速系统和水泵相接合的给水方式；由于消火栓超过十个，需设两条引入管。从不同的
4、方向引入。既保障了供水安全，又节约了能耗。排水系统：本设计采用污废水合流排放体制。管材采用了具有消声功能的螺旋UPVC排水管，设专用通气管的通气方式，为此可进一步提高环境质量。地下室内消防电梯井旁、泵房地面均设有集水坑和废水提升装置。消防系统：该建筑防火等级属于重危险级级，设计内容包括消火栓系统、自动喷水灭火系统和水雾系统。在屋顶设实验用消火栓装置，消火栓给水管网呈环状布置，各消火栓箱内设消防水泵启动电钮，能直接启动消防泵；室外设地下式水泵结合器，保证消防安全可靠。住宅走廊、消防前室设自动喷水灭火系统，地下室锅炉间设水雾系统。雨水系统：该建筑为大型商住楼，座落于城市的繁华中心地带，因此对建筑立
5、面要求较高，建筑的屋面高低落差较大故主要采用雨水内排水方式，以及少量的外排水。各系统中的立管设在管井内或沿墙敷设，水平管根据各系统的特点明敷或暗敷。本设计以经济、环保、节能为原则，通过借鉴以前的设计方法和经验，采用了合理的技术措施，使设计的各个系统达到了很好的使用效果。AbstractThe design of the building construction is a three-day water supply and drainage engineering design, including the main water supply system, drainage system
