Design of Integrated Prefabricated Rainwater Pumping Station and Its Storage Tank

摘要:

一体化预制雨水泵站具有占地面积小、施工工期短、集成化程度高等优点，目前在市政工程中应用较多，特别是在城市繁华地段，用地紧张，地面景观要求相对较高，这种泵站就显示出其独特的优越性。作为雨水排涝泵站，修建调蓄池是提高其排涝标准的有效方法。在实际运行时，可以根据降雨量调整泵站的排水量，避免泵站的集中流量对其下游排水系统的冲击，体现了“海绵城市及低影响开发”的设计理念。利用泵站集水池和调蓄池的水位关系来进行径流分配设施的设计、调蓄池空间的综合利用，是一体化雨水泵站的设计重点。

Abstract:

The integrated prefabricated rainwater pumping station has the advantages of small floor area, short construction period and high integration degree. At present, it is widely used in municipal engineering, especially in the engineering construction of urban prosperous areas. Due to the shortage of land and relatively high requirements of ground landscape, this kind of rainwater pumping station shows its unique advantages. As a rainwater drainage pumping station, the construction of storage tank is an effective way to improve its drainage standard. In the actual operation, the discharge of the pumping station can be adjusted according to the rainfall to avoid the impact of the concentrated flow of the pumping station on its downstream drainage system, which reflects the design concept of "sponge city and low-impact development". In the specific design, the relationship between the water levels of the collecting tank and the storage tank of the pumping station is used to design the runoff distribution facilities, and comprehensively utilize the space of storage tank, which is the key design point of integrated prefabricated rainwater pumping station.
