苏州华新大厦(写字楼)给排水设计(含CAD图)(任务书,开题报告,外文翻译,计算说明书14000字,CAD图30张)
摘要
本设计给水系统采用分区供水方式，分为三个区。负二层至二层为I区，由市政管网直接供水；三层至十一层为II区，采用变频泵加压供水；十二层至机房设备层为III区，采用变频泵加压供水。不锈钢生活水箱设在负二层泵房内。排水系统采用污、废水合流制，除WL-4、WL-6采用专用通气管外，其他各排水立管均采用伸顶通气管系统。负二层、负一层生活污水通过污水泵加压提升排放至室外检查井。根据规范规定，本设计属于一类公共建筑，室内消火栓系统流量为40L/s，水枪充实水柱取13m，消火栓栓口压力应不小于0.35MPa，且不大于0.5MPa。消火栓管网在室内成环状管网，竖管管径均为DN100，环网管径为DN200。在屋顶设试验消火栓一个，每个室内消火栓箱内均设有远距离启动消防泵的按钮。由于是公共建筑，本设计采用湿式自动喷水灭火系统，负二层泵房内设3组报警阀组，各层均设水流指示器和信号阀。负二层、负一层为中危II级，一层至十九层为中危I级。消防水池设在负二层，设置两个，分别在发生火灾时为消火栓系统和自动喷水灭火系统供水。消防水箱设在屋顶水箱间内，贮存有10min的自动喷水灭火系统和消火栓系统的用水量。出于美观等因素考虑，雨水系统采用内排式重力流排放。

The water supply and drainage design of Suzhou Huaxin Building
Abstract
The design of water supply system is partitioned water supply, divided into three zones. Negative story to story as I district, directly by the municipal water supply pipe network; three to ten layer of Zone II, variable frequency pump pressurized water; twelve stories to room equipment layer III area, variable frequency pump pressure water supply. Stainless steel water tank located in the living negative two pumping stations. This design uses sewage drainage system, wastewater Combined, except WL-4, WL-6 using a dedicated vent tube, other drain standpipe are used each stretch top vent system.Negative story, the negative layer of sewage through the sewage lift pump discharge pressure to the outside manholes. According to specification, the design belongs to a class of public buildings, indoor fire hydrant system flow rate of 40L / s, take the gun enrich the water column 13m, fire hydrant bolt port pressure should not be less than 0.35MPa, and not more than 0.5MPa.Hydrant pipe network in the interior into a ring network, standpipe diameter are DN100, ring network diameter of DN200. A fire hydrant located on the roof test. Each box has a fire hydrant fire pump remote start button. Because it is a public building, the design uses a wet sprinkler system. Negative two pumping stations equipped with three groups of alarm valve. The layers are set to signal valve and flow indicator. Automatic sprinkler system in negative story, negative one for the medium risk class II, in one to nineteen as I moderate risk level. Fire pond located in the negative story, set two, respectively, in the event of a fire hydrant system and automatic sprinkler system to water. Fire water tank located in the roof-top water tanks, water storage has a sprinkler system and fire hydrant system of 10min. For the consideration of the factors such as the beautiful, the rainwater system uses the discharge type gravity flow.
