南京某医院给水排水与消防工程设计.docx

设计总说明本设计为南京某医院给水排水及消防工程设计，设计的主要内容包括：建筑给水系统设计，建筑排水系统设计，建筑雨水排水系统设计，消火栓给水系统设计，自动喷淋系统设计本建筑地下一层，地上九层地下层为汽车库、自行车库和水泵房、仓库等，地上一层至四层为门诊部；四层与五层中间是设备层，层高为2.1m；五层至八层是医院住院部，层高为3.9m，九层医院管理办公用房市政管网压力为0.35MPa,由于本建筑属于高层建筑，室外管网只能满足下面几层的供水，所以给水系统采用分区供水方式地下一层至地上四层采用室外官网直接供水，五至九层采用变频调速恒压给水方式因为室外管网不允许直接抽水，则在地下一层设置贮水池本设计采用生活污水和生活废水合流制排水系统，卫生间采用污、废合流制排至室外污水检查井，诊室废水排至室外废水检查井医院卫生间污废水先经化粪池处理后，再与医院诊室废水汇合排至室外医院污水处理构筑物，经处理达标合格后排至室外污水管网排水立管设伸顶通气管或汇合通气管一层排水直接排至室外，地下室废水经潜污泵提升至室外检查井雨水采用的是内排水系统，雨水直接排至室外雨水管网消火栓系统包括室内和室外消火栓给水系统，该建筑物高度低于70米，，故消防不分区，低层设减压孔板减压。

消火栓保护半径为28.5米本建筑属于中危险级，其中地上部分为中危险级I级，地下一层车库属于中危险级 II级在建筑的诊室、大厅、病房等公共活动场所、走廊、地下车库等处均应设置闭式自动喷水灭火系统设3个湿式报警阀，报警阀后管网为枝状网，每层设水流指示器、信号阀，自喷系统竖向分三个区，与消火栓系统合用消防水箱重要设备用房等不宜用水消防的部位设置热气溶胶预制灭火系统关键词：建筑给水系统，排水系统，消火栓系统，自动喷淋系统AbstractThe design for a hospital in Nanjing Water and fire engineering design, design of the main contents include: building water supply system design, construction of drainage system design, architectural design of drainage systems, fire hydrant water supply system design, automatic sprinkler system design.The building has a basement, there are nine on the ground. The basement of the garage, bicycle storage and pump house, storage, etc., on the ground floor to four for the clinic; four and five are intermediate device layer, the height is 2.1m; five to eight hospital inpatient , the height of 3.9m, the nine-story office building is the hospital management.Municipal pipe network pressure is 0.35MPa, since the present building belongs to the high-rise buildings, outdoor pipe network water supply can only meet the following layers, so the water system is partitioned water supply. Basement to the ground four outdoor official website use direct water supply, five to nine frequency control constant pressure water supply mode. Because outdoor pipe network does not allow direct pumping in the basement set up storage tanks.This design uses sewage and domestic wastewater combined sewer systems, toilet use sewage, waste Combined sewage discharged to the outdoor manholes, office waste water discharged into the outdoor wastewater manholes. Hospital toilet after first septic tank sewage and waste treatment, and then the hospital clinic confluence wastewater discharge to the outside hospital sewage treatment structures, Standards Compliance treated sewage pipe network back to the outdoors. Drain riser extending top snorkel set snorkel or convergence. Floor drain directly to the outside row, waste water submersible sewage pump basement upgrade to outdoor manholes.Rainwater is used in the drainage system, rainwater directly to the outside row storm sewer.Hydrant system includes indoor and outdoor fire hydrant water supply system, the building height of less than 70 meters, it is not the fire district, the lower set pressure plate decompression. Hydrant protection radius of 28.5 meters.The building belongs to the dangerous level, which is the dangerous level above ground levell, basement garage below the dangerous level 2.grade. In office buildings, halls, and other public venues wards, corridors, underground garage, etc. shall be provided with a closed sprinkler system. Set up three wet alarm valve, pipe network after the alarm valve dendritic network, each set flow indicator, signal valve from the spray system is divided into three vertical zones, combination fire water tank and hydrant systems. Important equipment, buildings, etc. should not set the hot water for the site of aerosol fire extinguishing systems prefabricated.Keywords: building water supply systems, drainage systems, fire hydrant system, automatic sprinkler system1绪论 11.1 概述 11.2 设计原始资料及工程概况 11.3 设计目的 11.4 设计任务与要求 12设计说明 32.1 室内给水系统 32.1.1 给水系统选择 32.1.2 给水系统组成 42.1.3 加压设备及构筑物 42.1.4 管道的布置级敷设 42.2 室内排水系统 52.2.1 排水系统选择 52.2.2 排水系统组成 72.2.3 管材、管道的布置和敷设 72.3 雨水排水系统 92.3.1 雨水系统选择 92.3.2 雨水系统组成 92.3.3 管道的布置与敷设 92.4 消火栓给水系统的管道及设备的安装 102.5 自动喷水灭火系统的管道及设备的安装 112.6 气体灭火系统管道及设备的安装 112.7 建筑灭火器的配置 123设计计算 133.1 给水系统计算 133.1.1 给水用水量计算 133.1.2 给水管网水力计算 133.1.3 水泵的计算和选择 183.1.4 生活水箱容积计算 183.1.5 减压阀设置 193.1.6 室外管网水力计算 193.2 排水系统计算 193.2.1 生活排水系统设计 193.2.2 通气管计算 243.2.3 化粪池容积计算 283.2.4 污废水提升 283.3 雨水系统计算 293.3.1 暴雨强度计算 293.3.2 雨水量计算和雨水斗选用 303.3.3 管径确定 303.4 消火栓系统计算 313.4.1 .消火栓间距确定 313.4.2 消防管道系统计算 313.4.3 消防泵和稳压泵选择 343.4.4 室内消火栓压力计算 353.4.5 确定减压孔板孔径 363.4.6 高位消防水箱 373.4.7 消防贮水池 373.4.8 水泵接合器的选择 373.4.9 室外消火栓设置 373.5 自动喷水灭火系统计算 373.5.1 设计参数 373.5.2 .划分作用面积 383.5.3 自动喷淋系统水力计算 383.5.4 水箱高度计算 403.5.5 喷淋泵选择 423.5.6 减压阀设置 3.5.7 泵接合器的选择 3.6 气体灭火系统计算 结论 致谢 错误！.未定义书签。

参考文献 1绪论1.1 概述随着现代医学科学的快速发展，不断有新技术、新医疗设备出现，从而与之相符的现代化医疗建筑一一医院，也面临着新的设计理念和新技术的运用无论从医院建筑物功能、其所处的环境，还是医院建筑设备及装备系统，要求均愈来愈高因为它不仅是保障日常工作生活的需要，而且与救治病人、促进康复、避免致残、挽救生命紧密相关作为给排水专业的设计不仅需要满足医院建筑中设备上不同功能的要求，而且必须安全可靠1.2 设计原始资料及工程概况本工程总建筑面积21996.36m2,地上建筑面积16369.56 m2,地下建筑面积6037.78 m2建筑高度37.80m，地下一层，地上九层地下层为汽车库、自行车库和水泵房、仓库等，。
