摘要:本設(shè)計是徐州市高鐵時代廣場3號樓建筑給水排水工程設(shè)計,該建筑是地上為三十一層高層商業(yè)辦公樓，地上建筑面積36242m2，其中一層為小型商業(yè)用房，二至三十一層為辦公用房。 該建筑的給水排水設(shè)計主要包括高層室內(nèi)給水系統(tǒng)設(shè)計，高層建筑排水系統(tǒng)設(shè)計，高層消防系統(tǒng)設(shè)計以及高層熱水系統(tǒng)設(shè)計。生活給水系統(tǒng)：采用分區(qū)給水，共計四個區(qū)。經(jīng)水壓估算，31層共分成四個區(qū)，1-5層為低區(qū)，由市政直接供水，6-14層共九層為高一區(qū)，15-23層共九層為高二區(qū)，24-31層共八層為高三區(qū)。低區(qū)與高區(qū)均采用下行上給的供水方式；高區(qū)管道路徑為：城市管網(wǎng)-->地下生活水箱-->變頻調(diào)速水泵-->高區(qū)各層用水點。 排水系統(tǒng)：采用污、廢水分流制，排水系統(tǒng)設(shè)伸頂通氣管，污水經(jīng)化糞池處理后排入市政污水管網(wǎng)。 消防系統(tǒng)：采用消火栓給水系統(tǒng)，室內(nèi)消火栓給水系統(tǒng)采用臨時高壓給水，由消防水池、加壓泵、供水管、閥門、室內(nèi)消火栓等組成?；馂?zāi)初期10min的用水量由屋頂消防水箱供給，正常供水由消防水泵從貯水池內(nèi)抽取。室內(nèi)消火栓用水量和室外消火栓用水量分別取30L/S和40L/S。 熱水系統(tǒng)：采用封閉式機械循環(huán)熱水系統(tǒng)，分區(qū)情況與冷水系統(tǒng)一致，熱水系統(tǒng)采用容積式水加熱器供應(yīng)。 給水系統(tǒng)和熱水系統(tǒng)均采用PP—R給水管材，排水系統(tǒng)采用塑料排水管，消火栓給水系統(tǒng)采用熱鍍鋅鋼管。 設(shè)計中涉及到的管道布置、計算與安裝及設(shè)備選型，均應(yīng)遵循相關(guān)規(guī)范的要求，力求經(jīng)濟合理，簡潔高效。 關(guān)鍵詞 高層建筑；給水；消防；排水；熱水
Abstract:The design of No. 3 building water supply and drainage engineering design is the Xuzhou high-speed rail Times Square, the building is on the thirty-one floor high-rise commercial office building, a building area of 36242m2, one of which is a small commercial housing, two to thirty-one storeys for office space. Water supply and drainage design of the building includes the design of water supply system of indoor design of high-rise, high-rise building drainage system, design of high-rise fire system design and high hot water system. Life water supply system: water, for a total of four district. The hydraulic pressure estimation, the 31 layer is divided into four zones, 1-5 layer for low area, water directly by the municipal, 6-14 layer nine layers as high area, a total of nine layer 15-23 layer for the school district, a total of eight layer 24-31 layer for high school district. Low and high use down to the water supply pipeline; high path for city network: > life underground water > > high variable speed pumps the water. Drainage system: the sewage, waste water diversion system, drainage system equipped with the ventilating pipes, sewage is treated in the septic tank is discharged into the municipal sewage pipe network. Fire system: the fire hydrant water supply system, fire hydrant water supply system by using a temporary high-pressure water supply, fire water, pressure pump, water supply pipes, valves, fire hydrant etc.. The early fire 10min water from the roof tank fire water supply, fire water pump from the tank by extraction. Indoor fire hydrant water and outdoor fire hydrant water respectively with 30L/S and 40L/S. Hot water system: the closed mechanical circulating hot water system and cooling water system, the partition consistent, hot water system using volumetric water heater supply. Water supply system and hot water system adopts PP - R pipe for water supply, drainage system with plastic drainage pipe, fire hydrant water supply system using hot galvanized steel pipe. In the design of piping layout, relates to the calculation and installation and equipment selection, should be in accordance with the relevant requirements, economic rationality, concise and efficient.
