摘要
长湖水电厂投入运营已20多年,溢流面伸缩缝止水系统大部分失效,渗漏问题长期得不到解决。用弹性环氧砂浆修补溢流面伸缩缝缺陷,经2000年4月正常高库水位和泄洪考验,未见任何渗漏,堵漏效果良好。
It has been more than20years since Changhu hydroelectric station put into operation.The water -stopping system of expansion joints of spillway surface has lost its function mostly and leak problem is a long-standing issue.An epoxy remedy technique to deal with defect of expansion joints is introduced in this article.After experienced by high water level and flood -discharge in April,2002,no leak problem was found.
