十七层万都科技楼给水排水工程设计(含CAD图)

十七层万都科技楼给水排水工程设计(含CAD图)(任务书,开题报告,计算说明书12000字,CAD图25张)
摘  要
本工程为万都科技楼排水设计项目。该办公楼为 17 层，建筑总高度为 58.3m，负一层为地下车库，层高 4.5m，一层层高 4.2m，二、三层4m，标准层高 3.3m。
给水系统采取垂直分区并联给水的方式，从市政管网引两根引入管进入建筑，负一层至地上五层由市政管网直供，六层至十七层由无负压变频供水设备加压供水。本建筑属于一类高层民用建筑，耐火等级为一级，室外消火栓用水量40L / s ，室内消火栓用水量40L / s 。消火栓充实水柱高度 13m，水龙带长度 25m。本建筑喷淋系统采用湿式自动喷水灭火系统，地上部分为中危Ⅰ级，地下部分为中危Ⅱ级，分两个区，负一至七层为低区，八至十七层为高区。建筑内消防及喷淋在火灾前 10min 用水由屋面箱泵一体化消防增压稳压设提供，有效容积为36m3 ，后期灭火用水由地下一层的消防水池提供，其有效容积为600m3 ，分为两格。
室内外排水均采用污废合流制，经检查井直接排入市政污水管。排水立管采用通气立管的双立管排水系统，其中一层单独排水，二至十七层集中排水。地下室排水经排水沟汇集排至集水坑，经潜污泵提升排至检查井。本建筑屋面雨水排水系统采用内排水系统。

Abstract
This project is a drainage design project of Wandu Science and Technology Building. The total height of the office building is 58.3m. The negative floor is an underground garage with a height of 4.5m. The first floor is 4.2m, the second and third floors are 4m, and the standard floor is 3.3m.
The water supply system adopts vertical zoning and parallel connection. Two leading pipes are introduced into the building from the municipal pipe network. The negative one to the ground five layers are supplied directly by the municipal pipe network, and the six to seventeen layers are supplied by the non-negative pressure variable frequency water supply equipment under pressure. This building belongs to a kind of high-rise civil building. Its fire-resistant grade is first class. The water consumption of outdoor hydrant and indoor hydrant are 40L/s and 40L/s respectively. Fire hydrant filling water column height is 13m, water hose length is 25m. A test hydrant is installed on the roof, and a button to start the fire pump remotely is installed in each indoor hydrant box. The sprinkler system of this building adopts the wet automatic sprinkler fire extinguishing system. The above ground part is medium-dangerous grade I, and the underground part is medium-dangerous grade II. It is divided into two zones. The negative one to seven floors are low zones, and the eighth to seventeen floors are high zones. The alarm valve is located in the pump room of the basement. Flow indicator, signal valve and terminal water test device are installed in each layer. The signals are sent to the fire control center for processing. The water for fire fighting and spraying in the building is provided by the integrated pressure-boosting and stabilizing device of roof box pump 10 minutes before the fire. The effective volume is 36 m3. The water for fire fighting in the later stage is provided by the fire pool on the ground floor. Its effective volume is 6 60 m3, which is divided into two compartments.
Both indoor and outdoor drainage systems adopt the combined sewage and waste system, which is discharged directly into municipal sewage pipe through inspection wells. Drainage riser adopts ventilation riser double riser drainage system, one layer of which is drained separately, and two to seventeen layers of centralized drainage. The basement drainage is collected and discharged to the catchment pit through the drainage ditch, and is elevated and discharged to the inspection well by the submersible sewage pump. The roof rainwater drainage system adopts internal drainage system and gravity semi-pressurized drainage system. Rainwater is collected by roof rainwater bucket and discharged into municipal rainwater pipe network by rainwater riser
