映秀湾水电站是70年代修建在岷江上游干流上的第一座中型、径流调节、低闸取水的引水式电站。该电站首部枢纽的泄洪闸自1967年过水运行以来,闸底板、闸门底坎和底坎护板遭到了严重磨损。本文就泄洪闸底板磨损情况进行了介绍,对其原因作了分析,并对闸底板的抗冲耐磨保护谈几点认识。 Yingxiuwan Hydropower Station was built in the 70’s on the upper reaches of the Minjiang River on the first medium-sized, runoff regulation, low sluice water diversion power station. Sluice gates, sluice gates and underbody guards have been severely worn out since the flood gates at the station’s first hub have operated since 1967. In this paper, we introduced the condition of the sluice floor slab wear, analyzed the reason and discussed the impact and abrasion protection of sluice floor plate.
