【正文】 I摘 要根據題目要求設計了 17 層高層綜合樓的建筑給水系統、建筑排水系統、建筑消防系統（消火栓給水系統及自動噴水滅火系統） 、建筑屋面雨水排水系統設計。給水系統采用分區供水，低區負一到三層，由市政管網直接供水；中區四到十一層；高區十二到十七層。中區和高區采用無負壓變頻供水。排水系統采用污、廢水合流制，底層單獨排放，排水立管設伸頂通氣管，污水經化糞池處理后排向市政污水管網。消防系統分消火栓給水系統和自動噴水滅火系統。屋面雨水排水系統采用檐溝內排水。關鍵詞：高層建筑；給水系統；排水系統；消防系統IIABSTRACTBaised on the synthesis analysis, the water supply system, the drainage system, fire system(fire hydrant system and automatic sprinkler system) and roof drainage system for the level 17th high plex building are designed.The water supply system is applied by vertical division block. The floors from the negative to the third are the low areas, water of which is supplied directly by the municipal pipe work. The floors from the 4th to the 11th are the middle areas and the floors from the 12th to the 17th are the high areas,water of which are all supplied with the frequency conversion pump group. The drainage system is an interflow system of sewerage and waste water. Water of the first floor drains separately, the upright draining pipes are equipped with the ventilating pipes, and then the sewerage is disposed by the septic tanks and drains to the municipal waste pipe work. The fire system includes the fire hydrant system and automatic sprinkler system. The roof drainage system is an outside drainage system.
