解放后,山东河南两省沿黄大堤共建成涵闸80座。由于黄河河床的不断淤高,使同级流量水位逐年抬高,因而各闸的防洪水位也相继抬高,闸的防洪能力相应降低。为了提高各闸的防洪能力,必须进行改建加高,以适应抬高后的防洪水位,确保建筑物的安全。现就涵闸改建工作中的几个问题,谈一点认识。 After liberation, along the Yellow River in Shandong and Henan provinces built a total of 80 culverts. Due to the continuous siltation of the Yellow River bed, so that the same level flow elevation year by year, so floodgate flood control levels have also been raised, the flood control capacity of the corresponding reduction. In order to improve the flood control capability of each gate, alterations and heights must be carried out to meet the elevated flood control levels to ensure the safety of the buildings. Now on the Crane Rebuild several issues, talk about understanding.
