陆浑水库自2006年除险加固工程完工后,历经2010-2012年连续3年高水位考验,水库逐步达到正常运用标准。伴随近些年极端天气出现机率加大,水库遭遇大洪水的机率随之攀升,泄洪洞作为水库最为重要的控泄建筑物启用的频率同时增加。2010年大汛期间泄洪洞开闸泄洪,工作闸门提升初期,发生闸机房四周墙壁及玻璃窗产生振动、闸房顶部装饰面板大量脱落损坏,排查原因系因闸室密闭几近真空通气道进气量不足产生负压所致。文章通过产生振动现象的初步分析,为存在或发生类似问题的闸机房及生产车间提出解决办法及采取对策。
After the completion of the project of reinforcing and eliminating the danger in 2006, Luhun Reservoir has been tested by the high water level for three consecutive years from 2010 to 2012, and the reservoir has gradually reached the standard of normal operation. With the increased probability of extreme weather in recent years, the chances of reservoirs encountering big floods will increase. The frequency of flood control tunnels being the most important control and venting structures for reservoirs will increase at the same time. During the flood season in 2010 floodgate release gate flood, the work of the gate to enhance the initial period, occurred around the engine room wall and glass windows vibration, gate top decorative panels a large number of fall off damage, due to the closure of the chamber close to the vacuum vent intake Insufficient amount of negative pressure. Through the initial analysis of the phenomenon of vibration, this paper presents solutions and measures for gatehouse and production workshop for the existence or occurrence of similar problems.
