洪金灌区担负着金湖、洪泽两县30万亩水稻灌溉任务,渠首位于洪泽湖大堤上,为三孔钢筋混凝土穿堤涵洞,并有闸门控制。它不仅提供灌溉用水,而且还有抵御上游洪水,工程安全十分重要。 该涵闸1969年7月开工,1970年4月竣工,由于仓促上马,冬季施工,长期运行,年久失修,洞身伸缩缝错位,漏水严重,洞身混凝土严重碳化,上下游翼墙抗滑稳定不够等。所以江苏省水利厅非常重视,1991年大水后,即将该工程列入洪泽湖大堤加固计划,1994年初批准工程上马。
Hongjin Irrigation District is responsible for 300,000 mu of paddy irrigation tasks in Jinhu and Hongze counties. The canal head is located on the bank of Hongze Lake, and serves as a three-hole reinforced concrete tunnel with culverts and gate control. It not only provides irrigation water, but also to resist upstream floods, engineering safety is very important. The culvert was started in July 1969 and was completed in April 1970. Due to the hasty launch in winter, long-term operation, long-term disrepair, dislocation of the expansion joints of the tunnel body, serious water leakage, serious carbonation of the concrete body of the cave, Not enough. Therefore, Jiangsu Province, Department of Water Resources attaches great importance to floods in 1991, the project is about to be included in the Hongze Lake embankment reinforcement plan approved in early 1994 launched the project.
