一、设计总说明本工程为上海市某商业办公楼建筑给排水工程设计，设计的主要内容有：建筑给排水系统、雨水、消防以及节水系统。

该建筑：地下负二层，地面裙房三层，塔楼十七层。建筑面积57469㎡，其中地上建筑面积：38357㎡，地下建筑面积18712㎡。地下二层功能为车库,裙房功能为商业，塔楼功能为办公。建筑高度：79。95m。建筑分类：一类高层公共建筑。从市政道路引入DN200供水管并在地块内形成环状管网供商场用水，商场内雨污水管网齐全。本设计依据国家现行的设计规范，本着节能节水的宗旨，并以现有工程经验为基础，进行了室内给排水系统、室内自动喷淋灭火系统、消防系统和灭火器等的设计。79608

本工程水源为市政给水管，最低水压为0。16Mpa。计算得出最大日用水量237。54m3/d；消火栓系统的给水方式为临时高压给水，消防水源为市政自来水，接出两根DN200的引入管。市政管道在地块内成环状管网，供本项目所有用水。室内排水系统采用分流制，最高日总污废水量223。33m3/d(按生活用水量的90%计)。室内+0。000以上污废水重力流排出。地下二层车库隔油集水井内废水经潜污泵加压后排至室外污水管。室外污水管汇总后，再经化粪池处理排入市政污水管网。雨水设计流量638。99L/s，重力流排放。

  Design of water supply and drainage for a Commercial building in Shanghai

Design Description: The main content of the design is water supply and drainage engineering design for Shanghai, a commercial building。 

  Construction layers: two layers underground, Podium three layers on the ground, the tower 17 layers。 The construction area is 57469 square meters, including building area of 38357 square meters and the underground construction area of 18712 square meters。 The function of the ground floor is the parking lot and the function of the podium is commercial and the function of the tower is for the office。 Building height is 79。95 meters。 Building Classification belongs to the first class of high-rise public buildings。 The introduction of two DN200 water supply is piped in the mall into a ring layout from municipal road to for shopping malls, fire water shopping malls in the rain sewage pipe network complete。 This design is based on the current national design specifications, in the purpose of energy saving and water conservation, and based on the existing engineering experience, the indoor water supply and drainage systems, indoor automatic fire extinguishing system, fire systems and fire extinguishers and other design。

This water source of the project is municipal water supply pipe, and the minimum water pressure is 0。16Mpa。 Calculated maximum daily water consumption is 237。54m3/d。Fire hydrant system of water supply for the temporary high-pressure water supply, fire water for the municipal tap water, took out the introduction of two DN200 introduction tube。 Municipal pipelines in the block into a ring network, for the project all water。 The indoor fire hydrant water is 40L / s, outdoor fire water is 30L / s, and automatic sprinkler fire extinguishing system flow is 28 L/s。 Drainage system uses waste water and waste water flow system。 The highest daily total sewage waste water is 223。33m3/d (Calculated at 90% of the total water consumption life)。 Indoor +0。000 or more sewage wastewater gravity flow discharge。 The drainage water of the oil collection underground two floors of the parking lot is pumped in waste water by the submersible sewage pump pressure back to the outdoor sewage pipe。 After the outdoor sewage pipe summary, waste water is treated by septic tank and flows back into the municipal sewage pipe。 Rainwater flow is designed by 638。99L/s, and discharged by gravity flow。
