宜兴某百货大楼扩建工程给水排水设计(含CAD图)(任务书,开题报告,计算说明书10000字,CAD图21张)
摘要
本工程为宜兴某百货大楼扩建工程给水排水设计，为一高层建筑，本工程地下一层为停车场、设备用房;地上八层为商业用房;总建筑面积为12210m2，排水为雨、污、废分流。总建筑高度为34.5m
本建筑属于二类高层建筑,设计内容包括室内给排水系统、室内消火栓系统、自动喷淋系统、雨水系统。以建筑东侧人民中路城市给水管网作为水源，市政管网管径 DN300，干管埋深1.8m，供水水压为0.26MPa。给水系统所需压力H：根据经验，一层为100kPa，二层为120kPa，三层以上H=120+40×(n-2）kPa。故8层建筑所需水压大约为0.28MPa，地下一层到三层采用城市管网水压直接供水，四层以上采用地下室变频水泵机组联合供水。
本建筑火灾初期10min消防用水量由屋顶水箱供应，火灾10min后消防用水由湿式报警阀延时器后的压力开关自动启动消防水泵供应。室外消火栓用水量20L/S，室内消火栓用水量20L/S，火灾延续时间2小时。
根据环保的要求，结合室外给排水系统的设置，该建筑采用分流制排水系统，本建筑为百货大楼，生活废水少，故考虑将所有的污废水全部经室外化粪池处理后再排入城市下水道。屋面排水选用内排水，在屋面设雨水斗，在该建筑内部有雨水管道。

The water supply and drainage design of Yixing New Oriental Department store expansion project
Abstract
This works for the Yixing Oriental Department Store building expansion project of water supply and drainage design, is a tall building, this project underground parking, the equipment room; eight on the ground floor for commercial space; a total construction area of 12210m2, drainage for rain, sewage, waste water. The total building height of 34.5m.
The building belongs to the two type of high-rise building, the design content includes indoor water supply and drainage system, fire hydrant system, automatic sprinkler system, rain water system. Building water supply pipe network in East people's Road City as a source of water, municipal pipe diameter DN300, dry pipe depth is 1.8m, the water supply pressure is 0.26MPa. Water supply system of the pressure H: according to the experience, a layer of 100kPa, two for 120kPa, three layer above the H=120+40 * (n-2) kPa. The 8 storey building the required pressure is about 0.36MPa, the ground floor to the three layer of the city water pipe network of water supply, four layer above the basement of variable frequency pump water supply.
The building fire-fighting water consumption by the early 10min roof water tank fire water supply, fire after 10min by wet alarm automatically start the fire pump supply pressure switch valve delay after the. Outdoor fire hydrant water 20L/S, indoor fire hydrant water 20L/S, the fire lasted 2 hours.
According to the requirements of environmental protection, combined with the outdoor water supply and drainage system settings, the use of drainage system, the building is the department store building, life less waste water, so the sewage all the outdoor septic tank and then discharged into the city sewer. Roof drainage selection of internal drainage, let rain water bucket on the roof, water pipeline in the building interior.
