高幅水位变化取水方案的技术研究

Study on the Pontoon Pump Station Applied to Great Changes in Water Levels

趸船取水构筑物具有投资少、建设快、易于施工(无复杂的水下工程)等优点,有较大的适应性和灵活性。目前国内常规趸船取水方式主要适用于水源水位变幅10~35 m,但当水源水位变幅超过60 m时无设计应用先例。本文通过对某电厂取水工程中的多种取水方案进行研究、分析和对比论证,提出了一种适用于高幅水位变化的趸船取水技术,可供电力工程取水及其他取水工程借鉴参考。

Pontoon pump station has the advantages of less investment,fast construction(no complicated underwater engineering),greater adaptability and flexibility.At present the application condition of pontoon pump station are water level changes from 10m to 35m,and there is no application when the water level changes beyond 60m.Based on the study,analysis and comparison of several water intake solutions in a power plant in Guizhou province,a new kind of pontoon pump station which is proved to be the most appropriate method in the great water level changes situation is put forward.And it can be used as reference for electric power and other water intake projects.
