XXXXX大学毕业设计说明书XXX大厦给水排水及消防设计摘 要 XXX大厦位于内蒙古XXXX市，是一栋集办公、宾馆于一体的综合型高层建筑，建筑总高度为62.6米该建筑地下一层为配电室、水泵房、设备间等，室内地面标高为-4.35m；地上十七层，一层为接待大厅，层高为5.4m；二层为咖啡厅、餐厅及库房等，层高为5.4m；三、四层为写字间，层高为3.9m；五-十五层为客房，层高为3.6m；十六、十七层为办公、音像录制室，层高为3.9m；具体布置如工程图纸所示水源由市政给水管网提供，其常年压力为0.2MPa，埋深为1.8m，污水井最低水位为-1.2m水源由市政给水管网供给，建筑外侧设容积为810 立方米的贮水池，该设计给水系统采用分区供水方式，低区为地下一层至地上八层，高区为九层至十七层，高低区均采用变频调速水泵供水消防系统采用消火栓灭火系统、自动喷淋灭火系统和水幕系统相结合的方式，消火栓灭火系统管网布置成环状，共设四根消防立管，在裙房设置五根消防立管，每层设四个消火栓，在建筑外侧设两个水泵接合器，当水量不足时可由室外消防车通过水泵接合器供水自动喷淋灭火系统采用独立的湿式自动喷水灭火系统，该系统具有灭火及时，效率高的优点，但也存在缺陷，由于管网中充有有压水，当渗漏时会损坏建筑和影响建筑物的使用。

在系统设在每根立管上各设一组湿式报警阀，在建筑外侧也设两个水泵接合器，当水量不足时可由室外消防车通过水泵接合器供水水幕系统采用独立的干式自动喷水灭火系统，该系统设在每根立管上各设一组雨淋阀，在建筑外侧也设两个水泵接合器，当水量不足时可由室外消防车通过水泵接合器供水该建筑的功能决定了其对热水供应的要求很高，所以采用集中全天热水供应系统，冷水通过容积式加热器采用机械半循环系统加热后，经热水管网送到个用水点，为保证任何时刻均达到设计水温，设计采用容积式加热器该设计排水系统采用生活污水和生活废水合流排放，地下室污水采用单独排出，每根排水立管均设专用通气立管，通气立管顶部设汇合管，在建筑物顶部设两个伸顶通气管雨水系统采用内排水系统，设两个多斗雨水立管和十个单斗雨水立管，雨水斗采用79型，材料为钢板[关键词］生活给水管网、贮水池、消火栓、自动喷淋灭火系统、水幕系统、热水系统、雨水系统 Design about water supply 、drainage and fireof the wei li si buildingAbstractThe XXX building Building in the city of XXXX, Inner Mongolia, is a collection of office, hotel into an integrated-type high-rise buildings.The height of Building is 62.6 meters. The construction of the underground power distribution room floor, pump room, equipment room, indoor surface elevation of -4.35m; 17-floor, one of the reception hall, and the height of the second floor of 5.4m; Cafes, restaurants and the Treasury. 5.4m; high level of three, four levels of portal Scriptorium, and the height of 3.9m; five - to 15-story rooms, 3.6m; high level of 16, 17-storey office for the tape recording studios, and the height of 3.9m; specific layout as shown in engineering drawings. Water from the municipal water supply network to offer its perennial pressure of 0.2MPa and depth of 1.8m, sewage well to the lowest level -1.2m. Water from the municipal water supply network supply, construction lateral based volume of 8.1 cubic meters of storage tanks, The water supply system design using water district, the District of underground low to the ground floor complicated, high zone chiutsengta to 17 storeys District level have adopted the VVVF water pumps. Fire hydrant system adopts extinguishing system, automatic sprinkler systems and water curtain system combining, Fire Hydrant System network layout in a circle, which consists of four fire standpipe, the podium set up five fire standpipe, Four of each hydrant, located outside the building two pump adapter. When the water may be insufficient outdoor fire engines through the water pump adapter. Automatic sprinkler system using independent wet automatic sprinkler system, which has fire in a timely manner, The advantages of high efficiency, but also flawed, because pipe network is a fully pressurized water, When the leakage would damage the building and affect the use of the building. In the system in every root of all a set of wet alarm valve, outside the building was also set up two pumps adapter, When the water may be insufficient outdoor fire engines through the water pump adapter. Water curtain system uses independent dry automatic sprinkler system, which in every root of the various groups set up a deluge valve, in the construction of lateral also established two pumps adapter, when the water may be insufficient outdoor fire engines through the water pump adapter. The building's function to determine its water supply for the high demands and the use of centralized water supply system in the whole day, Volumetric water heater through mechanical circulatory half-heated, water-pipe network to water, To ensure that any at all times to achieve the designed temperature, volume design using heaters. The design of the drainage system using sewage and wastewater confluence emissions, a separate basement sewage discharges, per-up drainage pipe located Standpipe special ventilation, ventilation top riser pipe located convergence in the top of the building located two roof ventilator. Stormwater drainage system used within the system, set up more than two bucket rain Standpipe and 10 single bucket of water legislation, water bucket used the Model of 79, Materials for the plate.
