东平湖滞洪区是分滞黄河洪水 ,保证艾山以下窄河段防洪安全的重要工程 ,大清河戴村坝以下河道为东平湖回水段 ,与滞洪区具有不可分割的关系。长期以来 ,由于各方面的原因 ,东平湖滞洪区及大清河戴村坝以下的工程及安全建设达不到设计标准 ,因而不能保证滞洪区按设计条件安全运用。在分析东平湖滞洪区及大清河戴村坝以下各种工程及安全建设存在问题的基础上 ,提出了围坝和二级湖堤的加高加固、涵闸加固及大清河戴村坝以下各项工程的加固措施 ,并安排滞洪区的安全建设 The Dongping Lake flood detention basin is an important project of sub-hiding the flood of the Yellow River to ensure the flood control safety of the narrow reach below Ai Mountain. The channel below Daqiahe Dai Cunba is the backwater section of Dongping Lake, which has an inseparable relationship with the detention basin. For a long time, due to various reasons, the engineering and safety construction below the Dongping Lake detention basin and Daqinghe Dai Cun can not meet the design standards, so it can not be ensured that flood detention areas can be safely used according to the design conditions. Based on the analysis of the existing problems of various engineering and safety construction in Dongping Lake flood detention area and Daqinghe Daicunba, the following aspects are proposed: strengthening and reinforcement of the dam and secondary lake embankment, Reinforcement measures of the project, and to arrange safety construction in flood detention areas
