1 工程概况国那里引黄闸位于山东梁山县境内,建成于1967年春,为一联三孔钢筋混凝土箱形涵闸,单孔尺寸为5.0m×5.5m(宽×高,以下同),闸底板高程37.29m,采用一台活动式启闭机启闭闸门。涵洞全长31.5m,主要用于解决梁山、东平两县的东平湖及梁山湖南的约3.4万hm~2的农田灌溉用水,必要时辅助石洼闸分洪。经过30多年的运行,该闸存在设计防洪标准不足和防渗系统缺陷等严重问题,被列为“九五”期间黄河下游防洪工程的在编险点工程之一,必须进行除险加固。
1 Project Overview Guoluo Yellow River Diversion Project is located in the territory of Liangshan County, Shandong Province. Built in the spring of 1967, it is a three-hole reinforced concrete box culvert with a single hole of 5.0m × 5.5m (width × height, the same below) Elevation 37.29m, using a movable hoist gate opening and closing. The total length of the culvert is 31.5m, which is mainly used for irrigation of about 34,000 hm ~ 2 of farmland in Dongping Lake and Liangshan in Liangshan and Dongping counties and diversion of stony flood gates when necessary.
