控制性水泥灌浆技术在西藏老虎嘴水电站围堰防渗中的应用

Application of controlled cement grouting to anti-seepage of cofferdam for construction of Laohuzui Hydropower Station

老虎嘴水电站全年围堰防渗设计中,应用了控制性水泥灌浆技术,在确保防渗性能符合设计要求的情况下,达到了节约投资、缩短工期的目的。通过对控制性水泥灌浆工法的分析,为此类防渗施工积累了经验。

During the anti-seepage design of the cofferdam for construction of Laohuzui Hydropower Station, the target to save the investment and shorten the construction period has been got through the application of the controlled cement grouting under the condition of ensuring the anti-seepage characteristics to meet the design requirement, Based on the analysis made on the construction method of the controlled cement grouting, the experiences for this kind of antieepage construction are obtained.
