Abstract
This building is the large-scale comprehensive building, is located the center of a southeast city, the construction is highly 96.20 meters, total floor space approximately 50,000 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 draining water sanitary equipment, concrete gives the drainage system design to be as follows:
Water supply system:
This construction underground to ground four by outdoor municipal administration pipe network direct water supply, the water supply system of five to twenty-seven is the water pump、the roof water tank and the reducing value 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 system:
This design uses the dirt waste water parting emissions system. The tubing used had the shock resistance cast iron pipe waste. might further improve the environment quality for this. In the basement nearby the fire electricity stairwell, 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 levelⅠThe level, the design content including the fire hydrant system and sprays automatically system. In supposes the experimental fire hydrant installment in the roof water tank between, the fire hydrant service pipe net assumes the ring-like arrangement; Room peripheral equation below water 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.
Hot water system:
According to the design data, this construction demand us to provide hot water for ground four to twenty-seven.To ensure the balance of the cool water press and the hot water press at the same point,the pipe of hot water system following with the water supply system.
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 the reasonable technical measure, enabled the design each system to achieve the very good use effect.
Key word: for water ；Draining off water ；Hote water；The fire hydrant ；Spurting voluntarily pours .该建筑为大型综合楼，位于东南某市中心，建筑高度为96.20米，总建筑面积约5.0万平方米。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四层由室外市政管网直接供水，五至二十七层采用水泵、屋顶水箱和减压阀相接合的给水方式；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：
本设计采用污废水分流排放体制。管材采用了具有抗震功能的排水铸铁管，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中危险级Ⅱ级，设计内容包括消火栓系统和自动喷淋系统。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。
热水系统：
根据设计资料，本设计需对5-27层供应热水。为保证同一用水点的冷、热水压力平衡，热水管道沿着给水管道布置。
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；热水；消火栓；自动喷淋。
