摘 要
本設計為24樓建筑給水排水工程。該建筑地上二十四層，地下一層，建筑高度98.285m。設計內容包括給水系統，消防系統，熱水系統，排水系統及雨水系統。
給水系統采用分區給水，地下一層至四層為低區，由市政給水管網直接供水；五至十四層為中區，由生活水箱-水泵供水；十五至二十四層為高區，由生活水池-水泵供水。
消防系統分為消火栓系統和自噴系統。消火栓系統，采用水箱和水泵聯合供水的臨時高壓給水系統。自噴采用濕式自動噴水系統。火災初期10min的水由水箱供給，正常供水由消防水泵從貯水池內抽取。
熱水系統的分區與冷水系統保持一致，水加熱器設置在地下一層。
排水系統采用污水和廢水分流制排水系統，生活廢污水直接排入市政排水管網，生活污水經化糞池局部處理后再排入市政排水管網。
屋面雨水排水系統采用天溝外排水，雨水直接排向市政污水管網。
關鍵詞：給水系統；消防系統；熱水系統；排水系統；雨水系統
THE WATER-SUPPLY AND DRAINAGE ENGINEERING OF ZHONGHE
ABSTRACT
This project is the water-supply and drainage engineering of zhonghe．The building has 16 layers on the ground, a layer underground.The high of the building is 98.285m.The contents of this design is water-supply system; fire-fight system, hot water-supply system , Sewerage system , rain water system.
The water-supply system adopt the way of subregion，the -1~4rd floor is the low district,the source is the municipal water-supply net-work;The 5~14rd floor is the middle district，which source is the life basin ——pumps； The 15~24rd floor is the high district，which source is the life basin ——pumps.
Fire fight system is divided into fire hydrant system and sprinkler system.Fire hydrant is adopt a temporary high pressure water supply system with the association of the water tank and pumps. The sprinkler system adopt wets spray water fire extinguishing system．the -1~2rd floor is theⅠdistrict; The 3~5rd floor is theⅡdistrict; The 6~24rd floor is theⅢdistrict.The fire water of the early 10 mins is supply by the water tank, normal the water supply be pumped by the fire fight Pump from the Saving pond.
The hot water-supply system district is consistent with cold water-supply system，The water heaters are established in underground．
The sewerage system uses the sewage and the waste water separate-sewage system，the waste sewage to disperse into the municipal drainage pipe network directly．The sanitary sewage disperses into the municipal drainage pipe network after disposed in the septic tank．
The rain water system adopt outside drain the system, the rain water direct row to municipal soil pipe net.
Various systems use a design second current capacity to determine the caliber, for Draining water Design Standard carries on the piping arrangement and the placing according to Construction.
Key word: Water supply-system； Fire fight system；Hot water-supply system； Sewerage system； Rain water system
