黄河是一条多沙河流，每年有大量泥沙淤积，随着主槽的逐年淤积，黄河水位逐年抬高，设防水位也有所变化，为确保防洪安全，两岸大堤随着设防水位的抬高相应地进行了加高培厚．40多年来已进行3次复堤c但随着时间的推移，两岸一批引黄闸相继出现了一些不适应防洪要求的问题，如 The Yellow River is a multi-stream river, with a large amount of sedimentation every year. With the sedimentation of the main channel year by year, the water level of the Yellow River rises year by year and the waterproofing level also changes. To ensure the flood control safety, Carried out higher training thickness. Over the past 40 years, there have been 3 replies to the embankment.
