该项成果是在认真总结黄河中下游渠首引水防沙工程实践经验和教训的基础上，在山东省邹平引黄灌区张桥渠首建成橡胶坝引水防沙工程，并进行了工程运行管理技术研究及效益观测。该工程防沙效果较以前提高24％，提高灌溉供水保证率125％～33％，年减少引沙量62．92万m‘，年节省
Based on the experiences and lessons learned from the practice of diversion and sediment control in the headwaters of the middle and lower reaches of the Yellow River, this achievement was built into the rubber dam diversion and sediment prevention project in the canal of Zhangqiao in the Yellow River Diversion Project of Zouping, Shandong Province. The project operation management technology Research and benefit observation. The sand control effect of this project is increased by 24% compared with the previous ones, and the guarantee rate of water supply for irrigation is increased by 125% -33%, and the annual sediment discharge is reduced by 629,200 m 3. The annual saving
