摘要:在新世纪,建筑给排水将更突出以人为本的原则,并将重点调整到民用建筑与工业建筑并重,公共建筑与居住建筑并重,冷水供应与热水供应并重,走上全面、均衡、务实、安全的发展之路。

   本文针对丰源大厦,结合对设计标准、规范的理解,对该建筑的给水系统、排水系统、消防水系统、热水系统,主要以设计计算说明的形式,进行了初步探讨。

   根据设计资料,市政给水管网的水压为280KPa,分为低中高三个区:地下-1至5层为低区,由市政管网直接供水,采用下行上给方式;中区为6-12层,采用水泵—水箱联合供水,管网上行下给,中区水箱设置在转换层内。高区为13-16层,高区水箱在屋顶,管网上行下给。给水系统管材采用PP-R管。

   本建筑属一类建筑,设室内消火栓给水系统,室内消火栓用水量为20L/s,室内消火栓系统不分区,采用水箱—水泵联合供水,消防水箱贮存10分钟消防用水,消防泵及管道均单独设置。此建筑的火灾危险等级属于中危险Ⅰ级,设自动喷淋系统,其设计喷水强度为6L/(minm2),设计作用面积为160m2,系统喷头的工作压力为0.06MPa,用水量为20L/s。室内消火栓给水系统管材采用普通碳素无缝钢管,自动喷水灭火系统采用内外壁热浸镀锌钢管。

   本设计室内排水系统采用合流制,卫生间污废水经化粪池后直接排至室外排水管网,男、女厕所分别设置立管。排水系统首层单独排放,并就近排至户外。高区排水立管设有伸顶通气管。同时设置专用通气管,辅以结合通气管连接成三管系统。地下室积水经地沟排至集水坑,再通过污水提升泵排至室外城市污水管网。本设计排水管材采用柔性接口机制排水铸铁管。

   本建筑热水设计部分为2-5层东北侧淋浴间、厨房用水及13层公共浴室,采用集中式热水供应系统。2-5层的水加热器由市政供给冷水,13层公共浴室的水加热器由高区水箱供给冷水,均采用容积式水加热器,集中设置在地下室。本设计热水系统采用薄壁铜管,管件与管道的材质相同,水加热间内采用不锈钢管。

Abstract:In the new century,Water supply and drainage will follow people-oriented principle, and will be adjusted to focus on both civil and industrial buildings, both public buildings and residential buildings, both water supply and hot water and take a comprehensive, balanced, practical and safe developing way.

   In this paper, the project isfengyuan edifice. I will make the construction of water supply system, drainage system, fire water system, hot water systemwith the understanding of design standards and specifications, mainly in the preliminary design calculations .

   According to design information, municipal water supply network of the water pressure is 250KPa, pressurized water the way it is divided into upper、medium、 lower three zones: zone of -1-5 layers, directly by the municipal water supply pipe network, using down to give way; the area for6-12 layer, using the pump - joint water supply tank, pipe line under a row.The water tank set up in 13 layers.The upper area for 13-16 layers,the water tank set on the roof.Water supply system using PP-R pipe tube.

   The building is a first-class building, located fire hydrant water supply system, fire hydrant water for the 20L / s. Fire hydrant system is not partitioned by water tanks - water pump combined water supply, fire water tank for 10 minutes the fire water storage, fire pumps and pipes are set separately. This building is in danger of fire danger rating of grade Ⅰ,set automatic sprinkler system, designed to water density is 6, the design function area of 160, the system working pressure nozzle 0.06MPa, water consumption is 20L/s.Fire hydrant water supply system using ordinary carbon seamless steel pipe, automatic sprinkler system in galvanized steel pipe

   The interior drainage system is designed by combined, toilet waste water directly discharged into the municipal sewage pipe network.Male, female toilets were set up risers. The first floor separately emissions, and to the nearest row outdoors. Has a high drainage riser extending through the top of the trachea. Established special ventilation tube, supplemented with ventilation tube connected into three systems. Water discharge through the trench to the basement sump, sewage lift pump discharge and through to the outdoor urban sewage pipe network. The design of the drainage pipe with flexible interface mechanism drainage cast iron pipe.

   The architectural design is 2-5 layers of hot water the northeast shower, kitchen, water and 13 floors of public bathrooms,the use of centralized water supply system. 2-5 layers of the water heater cold water supply from Central water tank, 13-story public bathroom water heater cold water supply tank by the high area, volume of water heaters are used to focus set in the basement. The design of hot water system uses thin-walled tubes, pipe fittings and pipe use the same material, the water within a stainless steel tube heated.
