某公寓式酒店给排水工程设计(含CAD图)(任务书,开题报告,外文翻译,论文计算书41000字,CAD图30张)
摘 要
本设计一层至地上三层为市政管网直供，四至三十三层为水泵供水的给水方式。直供部分从市政给水管网接2根DN50的引入管入A座一根DN70的管进B座，另两根DN150的引入管接至地下的生活水池和消防水池。生活水池为不锈钢生活水箱，消防水池采用砖砌混凝土结构，放置地下一层。排水采用生活污、废水合流制，通气管均采用专用通气立管通气。泵房排水槽经汇集排至地下一层集水坑，经潜污泵提升排至检查井后排入市政排水管。建筑四层以上的生活污水管在三层吊顶内，将各单元生活污水管适当汇集转换到排水立管后排出室外。屋面雨水经屋面雨水斗收集后由雨水管排至地面作散水。
根据规范，该建筑为一类建筑，属中危Ⅰ级。室内消防流量40L/s。充实水柱取12m，水龙带长度取25m，水枪喷嘴流量5.2L/s，消防立管管径为DN100、DN150。在顶层设试验消火栓一个，每个室内消火栓箱内均设有远距离启动消防泵的按钮。
该建筑采用湿式自动喷淋灭火系统，报警阀设于地下一层，各层均设水流指示器和信号阀，其信号均送入消防控制中心进行处理。各层均采用自动喷淋系统，地下一至三层采用直立式喷头。各层均设末端试压装置以及放空管。本工程的自动喷水灭火系统分A座分3个区，B座分4个区。屋顶水箱为36立方米，贮存有10min自动喷水灭火系统、室内消火栓系统用水量。自动喷水灭火系统和消火栓系统的初期灭火由水箱供水，后期供水由地下室的消防水泵和自喷泵供水，各支管与立管连接处设置减压孔板。
根据重力式雨水系统和虹吸式雨水系统的设计分析及造价对比后，本设计采用重力式屋面雨水排水系统.
本建筑物内对二至三十三层设置集中太阳能供热水，预留室内热水器管道。

Abstract
In this design, the first floor to the ground floor is the direct supply of municipal pipe network, and the fourth to thirteenth floors are the water supply methods of water pumps.The direct supply part connects two DN50 inlet pipes from the municipal water supply network into block A, one DN70 pipe into block B, and the other two DN150 inlet pipes into the underground living pool and fire fighting pool.The water tank is stainless steel water tank, and the fire water tank is made of brick and concrete.The drainage is made of domestic sewage and waste water, and the ventilation pipes are made of special ventilation riser.The drainage tank of the pump house is collected and discharged to a water collecting pit on the ground floor, and then it is hoisted and discharged to the back of the inspection well into the municipal drainage pipe by the submersible sewage pump.The domestic sewage pipe with four or more floors in the building is in the ceiling of three floors, and the domestic sewage pipe of each unit is properly collected and converted to the drainage riser and then out of the room.Roof rainwater is collected by roof rain buckets and then discharged to the ground by water mains.
According to the specification, the building to building, belong to the dangerous Ⅰ level.Indoor fire flow 40L/s.Fill the water column with 12m, hose length with 25m, nozzle flow rate of water nozzle with 5.2l /s, pipe diameter of fire riser with DN100 and DN150.A test hydrant is set on the top floor, and a button to start the fire pump at a distance is set in each indoor fire hydrant box.
The building adopts a wet automatic sprinkler fire extinguishing system, and the alarm valve is located on the ground floor. All floors are equipped with water flow indicator and signal valve, and the signals are sent to the fire control center for processing.Automatic sprinkler system is adopted for each floor, and vertical sprinkler head is adopted for one to three floors underground.The terminal pressure test device and air vent pipe are installed on each layer.The automatic sprinkler system of this project is divided into three zones in block A and four zones in block B.The roof water tank is 36 cubic meters, and there is water consumption for living, automatic sprinkler system for 10min and indoor hydrant system.Automatic sprinkler system and fire hydrant system in the early fire extinguishing by water tank water supply, water supply from the basement of the late fire pump and the water injection pump, each branch pipe with vertical pipe joint set decompression orifice plate.
According to the design analysis and cost comparison of gravity rainwater drainage system and siphon rainwater drainage system, this design adopts gravity roof rainwater drainage system.
The building is equipped with concentrated solar heating water on floors 2-3, and indoor water heater pipeline is reserved.
Key words: water supply system, drainage system, hydrant system, automatic sprinkler system, rainwater system
