Abstract

Abstract: This paper introduces the erosion of the concrete of the left spillway of Lijiaxia hydropower station after long time water discharge. Based on deterioration inspection and cause analysis, concrete repairing material has been chosen and a target-oriented repairing scheme was established, worthy reference.

Key words: spillway, erosion, silica fume concrete, SK brush polyurea

摘要： 介绍了李家峡水电站左底孔泄水道经过长时间泄水后边墙混凝土冲蚀破坏的情况，经过对左底孔泄水道的缺陷检测和成因分析，有针对性地制定了施工方案，优选了混凝土缺陷修补材料。本工程选择的修补方案及施工技术可在类似工程中推广应用。
