【正文】 學(xué)生姓名 專業(yè)名稱 給水排水工程 指導(dǎo)教師 環(huán) 境 與 市 政 工 程 系 2022 年 6 月 4 日 濟(jì)南市星河飯店給水排水設(shè)計(jì) 摘 要 本設(shè)計(jì)為濟(jì)南市一幢 20 層的綜合樓，建筑總高度為 。 地上 20 層，地下 1 層 。 本設(shè)計(jì)包括：給水系統(tǒng)、排水系統(tǒng)、熱水系統(tǒng)、消火栓給水系統(tǒng)、自動(dòng)噴水滅火系統(tǒng)。因 地下室無(wú)用水器具，故不對(duì)其供水。 排水系統(tǒng)： 4~20 層的室內(nèi)排水采用污、廢分流排水體制，并采用直接伸頂通氣和三立管排水系統(tǒng)的管道布置型式。 熱水系統(tǒng)：采用集中熱水供應(yīng)系統(tǒng)，分區(qū)范圍基本與給水系統(tǒng)保持一致，中區(qū)為 4~12層，高區(qū)為 13~20層。各區(qū)熱水循環(huán)管網(wǎng)自成系統(tǒng)，采用容積式水加熱器，并集中設(shè)置在建筑物的地下室設(shè)備層，干管循環(huán)方式，循環(huán)泵機(jī)械強(qiáng)制循環(huán)。室內(nèi)消火栓給水系統(tǒng)與生活給水系統(tǒng)分開(kāi)設(shè)置。整個(gè)系統(tǒng)布置成環(huán)狀，并設(shè)有 3套水泵接合器。采用濕式自動(dòng)噴水滅火系統(tǒng)，由地下室的噴淋水泵和屋頂消防水箱供水。報(bào)警閥組前供水管道采用 環(huán)狀布置，報(bào)警閥組后各層供水分干管起端設(shè) 1個(gè)水流指示器。 18th to 20th floors is used for apartmentstyle office. This design includes the water supply system design, the drainage system design, the hotwater system design, the hydrant water supply system design and the sprinkler system design. Water supply systems: the water supply model of this building is zoned water supply. There is no water apparatus in basement where do not need water supply. In this building, 1st~3rd floor is lower zone, which is downfeed mode directly supplied by the municipal water supply work。 13th~20th floor is high zone which is uplink and down watersupply mode supplied by water pumps and roof tanks. Drainage system: the drainage system of 4th20th floor is separate mode for feces wastewater and other wastewater, including three standpipes and stack vent. The drainage system of 1st3rd floor is bined system which is drained to the outside drainage system. Hot water system: This building uses a centralized hotwater supply system which consistent with water supply systems. 4th12th floor is central zone and 13th20th floor is high zone. As the points of distribution in 1st3rd floor are less, there is not a hot water supply system there. Hotwater system in each zone is independent, using volume mode water heaters and concentrated layer equipment installed in the basement of the building, in which the main pipe cycle use pump to circling. Hydrant water supply systems: The building height is over 50 meters which is the first class of highrise buildings, in which indoor hydrant system is separated from domestic water supply system. The hydrant water supply system hasn’t been zoned. The entire system is a circle mode with 3 sets of water pump adapters. Sprinkler system: Since the risk level of the building is first class dangerous level, the sprinkler system is wet auto sprinkler system which is supplied from the pumps in basement and roof water tanks. There are 3 sets of alarm valve group and 2 sets of pump adapters. Behind the alarm valve group, there is a water flow indicator at the initial section of water supply submain pipe.
