1、 XXXXX大学本科毕业设计说明书 摘 要 该建筑为大型商场，位于药王大街北面，建筑高度为51.80米，总建筑面积约4.5万平方米。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五层由室外市政管网直接供水，六至十层设有变频调速系统 和水泵、屋顶水箱相接合的给水方式；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，升顶通气方式，为此可进一步提高
2、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中危险级级，设计内容包括消火栓系统，自动喷淋和水幕系统。在屋顶水箱间内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。商场，走廊，办公间，电梯前室设闭式自动喷淋系统，自动扶梯旁的防火卷帘处设置水幕系统。雨水系统：该建筑为大型商场，座落于城市的繁华中心地带，因此对建筑立面要求较高，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。热水系统：由于该系统用水仅包括商场内服务人员和办公人员饮用开水，所以
3、只设电开水加热设备。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。关键词：给水；排水；消火栓；自动喷淋。AbstractThis building is the large-scale market, is located northern side the god of medicine avenue, the construction is highly 51.80 meters, total floor space approximately
4、45,000 square meters. This building possesses for water draining water presses the high-rise construction to request for draining water to carry on the design. Unifies the actual situation, according to the building nature, the use, is equipped with the consummation with the room in for the water dr
5、aining water sanitary equipment, concrete gives the drainage system design to be as follows:For aqueous system: This construction underground to ground five by outdoor municipal administration pipe network direct water supply, six to ten gives the square water pitcher type which is equipped with the
6、 frequency conversion velocity modulation system and the water pump, the roof water tank joins; Because the fire hydrant surpasses ten, must suppose two lead-in tubes. From different direction introduction. Both has safeguarded the water supply security, and saved the energy consumption. Drainage sy
7、stem: This design uses the dirt waste water confluence emissions system. The tubing used had the noise elimination function screw UPVC discharge pipe, rose to go against the ventilation way, might further improve the environment quality for this. In the basement nearby the fire electricity stairwell
8、, the pump house ground are equipped with the sump and the waste water lifting gear. Fire prevention system: This building fire protection rank belongs to the dangerous levelThe level, the design content including the fire hydrant system, sprays automatically with the water curtain system. In suppos
9、es the experimental fire hydrant installment in the roof water tank between, the fire hydrant service pipe net assumes the ring-like arrangement, in various fire hydrants box supposes the fire pump to start the push-button, can the line start fire extinguishing pump; Room peripheral equation below w
10、ater pump coupler, guarantee fire prevention safe reliable. The market, the corridor, the work, in front of the elevator the room supposes the closed type to spray the system automatically, nearby escalator fire protection volume curtain place establishment water curtain system. Rain water system: T
11、his building is the large-scale market, is located in the city lively heartland, therefore sets up the surface request to the construction to be high, the construction roofing height dropping variance compares the death of a parent mainly to use in the rain water to drain water the way, as well as f
12、ew outside drains water. Hot water system: Because this system water used only includes in the market the service personnel and the work personnel drinks the boiling water, therefore only supposes the electricity boiling water heater. In various systems pipe riser is located in the tube well or alon
13、g the wall placing, the horizontal tube acts according to various systems to point out especially spreads or spreads darkly. This design take the economy, the environmental protection, the energy conservation as a principle, through profits from beforehand design method and the experience, has used
14、the reasonable technical measure, enabled the design each system to achieve the very good use effect.
