摘 要
本工程建筑面積約4.5萬平方米,。地下2層,地上20層辦公綜合樓。建筑總高度為 79.93 米。系一類高層民用建筑。地下兩層為車庫，1-3層為票據市場，4-15層為辦公區，16-19層為賓館，20層為餐廳。本次設計所需要解決的是建筑內的給水系統，污水系統，雨水系統，消防系統及熱水系統的設計，滿足人們日常生活的需求。本次設計需要解決主要問題是各系統的選型，各系統管道的布置與敷設及相關計算。水源：市政給水：室外管網水壓0.10～0.28Mpa；給水管徑DN300。
排水：雨水、污水均排入城市污水管網。市政管網雨、污水分流。暴雨強度等相關資料按江蘇溧陽地區在設計手冊上查找。
建筑條件:建筑物耐火等級一～二級; 火災危險等級為中危險級。
設計內容：給水，熱水，污水，廢水，雨水，消防，自噴系統。
供水系統共分三個區，低區：地下室和商場部分即-2~4層為低區，由市政給水管網直接供水；中區：5～15層設一組變頻水泵供水；高區：賓館和餐廳部分16～20層，供入高位水箱再供給。水泵房設在地下室。水箱容積為100m3，采用不銹鋼成品水箱。變頻供水設備的供水流量按各區的設計秒流量，壓力可保證頂層的供水壓力不小于0.1MP
賓館和辦公樓部分設集中熱水供應，熱源為鍋爐房提供的高溫蒸汽，通過熱交換器產生熱水。熱水主要供高區的賓館和中區的辦公樓，設計供水溫度為60℃。
室外排水采用雨污分流制，室內排水廢污分流。
消火栓系統在地下水泵房內設高區和中低區合用一套消防水泵，消防管道成環狀布置，豎向以設備層一為界采用減壓閥分區，減壓閥閥后壓力0.2Mpa，上下區靜壓均不超過1.00Mpa；5～10層采用減壓型消火栓，以保證栓口壓力不超過0.50MPa。
自噴系統在地下水泵房內設二臺自噴給水泵，控制配水管壓力不超過0.4Mpa并且滿足火災初期最不利點噴頭的噴水壓力。

Abstract
The project construction area of about 4.5 million square meters. 2 underground floor, ground floor, 20-storey office complex. Total building height of 79.93 meters. Department of a class of senior civil construction. Two floors underground garage, 1-3-tier market for the notes for the 4-15-storey office area for the hotel, 16-19th floor, 20th floor for the restaurant. The design needs to be addressed is the building's water supply system, sewage system, water system, fire system and water system design to meet the needs of daily life. The design needs to solve the main problem is the system of selection, the system layout and the laying of pipelines and related calculations. Water: Municipal Water: outdoor pipe network water pressure 0.10 ~ 0.28Mpa; Water pipe diameter DN300. Drainage: rainwater and sewage are discharged into urban sewage pipe network. Rain municipal pipe network, sewage diversion. Storm intensity and other related information by Jiangsu Liyang area find in the design manual. Construction Conditions: The fire resistance level of 1 ~ 2 buildings; fire danger rating for the risk level. Design elements: water, water, sewage, waste water, rain, fire, since the spray system. The water supply system is divided into three areas, the low zone: part of the basement and shopping malls that -2 to 4 layers for the low zone, directly by the municipal water supply to the water supply network; Central District: 5 ~ 15 levels set a variable frequency pump water; High District: the apartments and the restaurant part of the 16 to 20 layers for the high water tank and then into the supply. Pump room in the basement. Tank volume of 100m3, finished with stainless steel water tank. Variable water flow rate of water supply equipment Design Flow of districts, the pressure can be guaranteed not less than the top of the water supply pressure 0.1MPa Hotel and office part of the set concentration of hot water, heat for the steam boiler to provide heat, hot water generated by heat exchanger. Water primarily for the high zone in the area of apartments and office buildings, the design water temperature is 60 ℃. Outdoor water use of rain and sewage diversion system, interior drain waste and sewage separation. Groundwater pumping station equipped with fire hydrant system in the high zone and low zone 2 fire pumps, fire pipeline into the ring arrangement, the vertical to the device layer is bounded by a valve area, after the regulator valve pressure 0.2Mpa, up and down District static pressure not more than 1.00Mpa; 5 ~ 10 layers of vacuum-type fire hydrants to ensure that population pressure does not exceed bolt 0.50MPa. Since the spray system in the groundwater pumping station equipped with two sets flowing to the pump, control with no more than 0.4Mpa water pressure and to meet the most unfavorable initial point of the fire sprinkler water spray pressure.
