供水发电隧洞洞身施工现场狭窄并有障碍物 ,进口的塔筒、排架柱要一次连续地完成水平和垂直运输 ,用其他运输工具施工较为困难 ,结合这些工程特点施工中采取了泵送混凝土技术。本文从混凝土泵型的选择、泵送混凝土配合比的确定以及泵送混凝土的工艺流程、泵送混凝土的质量控制等几个方面介绍了泵送混凝土技术在汾河二库工程中的应用。 Water supply tunnel tunnel body construction site is narrow and there are obstacles, the import of tower, column to a column to complete a continuous horizontal and vertical transport, construction with other transport facilities more difficult, combined with the construction of the project took the construction of pumping concrete technology. This paper introduces the application of pumping concrete technology in the second reservoir of Fenhe River from the aspects of the selection of concrete pump type, the determination of pumping concrete mix ratio, the process flow of pumping concrete and the quality control of pumping concrete.
