摘要

本工程位于扬州市邗江区，总建筑面积约14300平米，其中：地上建筑面积11800平米，地下2500平米，占地面积1330平米。该建筑为框架—剪力墙结构，地上十层，地下一层，总高度39.3米，首层高度4.5米，二至十层层高3.3米[1]。

本建筑总高度39.3米，为高度大于24m的公共建筑，属于高层公共建筑。为保证建筑供水的安全可靠性，本设计中办公楼给水系统采取竖向分区供水，充分利用室外给水管网的水压，达到节能减排的目的。因此供水方案为：建筑一至五层，利用市政管网中水压直供，六至十层生活用水通过变频无负压供水设备进行加压供水。从建筑东北侧市政给水管网中接入管道引水至地下一层，然后通过变频无负压给水设备将水输送至高区楼层进行供水。办公楼内部用水采用上行下给的方式给每个用水点供水。本设计办公楼为二类高层公共建筑，火灾危险等级为中危Ⅰ级，经计算消防水池有效容积为489.6。消火栓系统工作时由地下泵房从消防水池取水后经消火栓泵加压后给着火点消火栓加压供水。喷淋系统采用湿式灭火系统，喷淋系统工作时由地下泵房从消防水池取水后经喷淋泵加压后给着火点喷头加压供水。平时消火栓和喷淋系统由屋顶消防水箱保持常压稳压状态，保证建筑消防系统的安全可靠性。本学生公寓排水设计雨污分流，生活污水通过重力排水排入市政污水管网，雨水通过重力排水排入雨水管网[2]。地下室污水汇集到集水坑后由潜污泵压力排水排入污水管网。本学生公寓污水系统采用双立管系统，设置通气立管，保证排水的通畅。本设计屋面雨水采用内排水，保证了建筑物的美观，同时屋顶设计溢流口。办公楼二层以上阳台露天，因此通过地漏汇集雨水后设置雨水排水管道。

Abstract

The project is located in Hanjiang district, Yangzhou city, with a total construction area of about 14300 square meters, of which: 11800 square meters above ground construction area, 2500 square meters underground, covering an area of 1330 square meters. The building is framed as a shear wall structure with 10 storeys above ground and 1 storey below ground. The total height is 39.3 m, the first storey is 4.5 m and the second to tenth storey is 3.6 m.

The total height of the building is 39.3 meters. It is a public building with a height greater than 24 meters. It belongs to a high-rise building. In order to overcome the drawbacks of the same water supply system in high-rise buildings and the excessive hydrostatic pressure in Low-Rise pipelines, and ensure the safety and reliability of water supply in buildings, the water supply system in high-rise buildings should adopt vertical zoning, and the zoning should make full use of the water pressure of outdoor water supply network in order to save energy. The first to fifth floors of the building are supplied directly by the municipal pipeline network, and the sixth to tenth floors are supplied by non-negative pressure water supply equipment. The water is diverted from the municipal pipeline network to the underground floor, and then the water is conveyed to the high floors of the district by non-negative pressure frequency conversion water supply equipment for water supply. Considering that the building is the municipal pipe network pressure and variable frequency speed pump water supply mode, so the downward upward water supply is adopted[2]. This building is a second-class high-rise public building, the design flow of outdoor hydrant is 40L/s. This building belongs to other public buildings. The fire duration of canceling the fire hydrant system is 2 hours. The design flow rate of fire hydrant in the second type high-rise public buildings is 20 L/s, while the number of water guns is 2, and the minimum flow rate of each vertical pipe is 10 L/s. The building is an office building with fire danger grade of medium danger grade I. The basic design parameters of the wet system should not be lower than the sprinkler strength 6 (L/min*m2) specified in Table 5.0.1, and the area of action is 160 m2. Rainwater and sewage are diverted in this building. Domestic sewage is connected to municipal sewage pipe network. Rainwater is discharged into adjacent rainwater outlets. Basement sewage is collected into catchment pits and discharged into rainwater outlets or inspection wells by submersible sewage pumps. The sewage system of this building adopts double risers, with ventilation risers. The design of roof rainwater using internal drainage system, while the roof design spillway. The balcony of this building is open-air. Rainwater drainage pipes should be installed.
