Analysis and Discussion on Application of Integrated Prefabricated Pumping Station in Municipal Underground Passageway

摘要:

一体化预制泵站可工厂组装和预制，具有自身系统集成度高、施工工期短、运维成本低、易与周围环境融合等优点，是高效增益的给排水加压设备。结合南昌市东站北路下穿地下通道工程实例，阐述一体化预制泵站应用于市政道路地下通道雨水提升排放时，设计中各要素如汇水面积、降雨历时、径流系数等的计算或选定，采用“设计-校核”“公式-模型”双重验算的方式，计算校核设计雨水量，探索下穿通道一体化排水泵站方案并对其安全性进行讨论。

Abstract:

Integrated prefabricated pumping station can be factory-assembled and prefabricated, has the advantages of its high system integration, short construction period, low operation and maintenance costs, and easily integrating with the surrounding environment, and is a highly efficient gain of water supply and drainage pressurization equipment. Combined with the Nanchang City East Station North Road Underpass Project, the calculation or selection of each factor such as catchment area, rainfall duration and runoff coefficient in the design are described when the integrated prefabricated pumping station is applied in the rainwater lifting and discharge of municipal underpass. The double checking calculation mode of "design - verification" and "formula - model" is used to calculate and check the design rainwater volume. The integrated drainage pumping station scheme of underpass is explored and its safety is discussed.
