摘要
三门峡水库污物来源与组成、来污时间与污物量、污物在坝前水域的流态及分布等,有其自身特点与规律性。污物以韧性极强的芦苇根为主,极难切割及与栅体分离,其他水库成功应用的清污技术在该水库很难发挥作用。数十年来,经过建设、改造拦污栅及拦污浮排试验,应用清污机、液压抓斗、150t悬臂吊、25t塔吊、30t回转吊、机动清污船与坝前栈桥等设施、设备,并通过回转栅式清污、提栅导栅清污、拦污浮排清污、齿耙式回转清污、液压抓斗清污、导排清污、机械与人工打捞清污等技术试验和探索,三门峡水库清污措施更加高效和实用,整体清污工作取得良好的效果。
The source and composition of the trash in Sanmenxia Reservoir, the coming time and the trash quantity, the flow state and distribution of the trash in front of the dam, etc, all above have their own characteristics and regularity. The trashes are mainly reed roots with high tenacity, and very hard to cut off from the trash rack ; the large tree roots can be seen everywhere under water. The successful trash-cleaning technologies of other reservoirs are of no use here. For decades, by construction and transibrmation of the trash rack and trash-cleaning test, using trash-cleaning machine, hydraulic grab, 150 t cantilever crane, 25 t tower crane, 30 t rotation crane, engine driven trash-cleaning ship, trestle in front of the dam, etc, and rotating fence rack, lifting fence rack, suspension-row block, rotation-tooth rake, hydraulic grab, guide outflow, mechanical and manual clean-up technology tests and research, through strengthening the management of trash-cleaning work, the measures of trash-cleaning are more efficient and practical and the overall effect has achieved obtains important progress.
