Abstract

Abstract: By one-year operation of Yayangshan hydropower station with low water level, failure of steel lining of the draft tube of unit No. 2 and separation between the tube and the concrete are found. By cause reason analysis, backfill grouting is adopted for treatment.

Key words: elbow draught tube, steel lining, failure, analysis, backfill grouting

摘要： 崖羊山水电站在2016年低水位运行一年后，发现2号机组尾水肘管钢衬撕裂脱落、混凝土脱空，通过原因分析，制定回填灌浆处理措施。
