Excavators and crushers waved their arms back and forth, and the construction workers were scattered in their respective posts racing against time to build ...... Recently, at the site of the Heilongtan Reservoir Dam Reinforcement Project of the National Debt Water Conservancy Project, there was a busy scene as far as the eye could see.
The maximum storage capacity of Heilongtan Reservoir is 360 million cubic meters, the normal storage capacity is 300 million cubic meters, the designed irrigation area of the irrigation area is 1,209,300 mu, and the controlled irrigation area is 911,300 mu, which irrigates Meishan Renshou County, Leshan Jingyan County and Chengdu Jianyang City respectively, and is responsible for providing production, living and industrial water supply to more than 3 million people in Meishan East Slope District, Renshou County, Qingshen County, Pengshan District, Tianfu New Area Meishan Area and Leshan Jingyan County. The main construction contents of the Heilongtan Reservoir Dam Risk Removal and Reinforcement Project include the main dam seepage prevention and reinforcement, the demolition and reconstruction of the spillway control section, the maintenance and reinforcement of the water crossing section of the drainage channel section and the pick-up section, the river channel improvement of the downstream of the spillway, the improvement of the Yangliu diversion canal, the maintenance and reinforcement of auxiliary dams such as Liujiagou, etc., with a total investment of 148 million yuan. The project is currently carrying out the grouting of the left and right abutments of the main dam and the removal of the spillway, and is expected to be completed by the end of November this year.
It is understood that after the completion of the project, the potential safety hazards of the dam will be eliminated, so that the Heilongtan Reservoir project can give full play to the comprehensive benefits of the original design, which is conducive to ensuring the safety of water supply and water, improving the regional ecological environment, and ensuring the safety of life and property of the downstream people. At the same time, it can enhance the flood control, irrigation and storage capacity of Heilongtan Reservoir, continue to improve social and economic benefits, and play a positive role in promoting the rural revitalization of irrigation areas.
