In the report of the 20th National Congress of the Communist Party of China, the requirements on "deeply promoting environmental pollution prevention and control, and continue to fight the battle to defend blue sky, clear water, and clean land" and "accelerate the implementation of major projects for the protection and restoration of important ecosystems", made Zhou Shangti, a senior engineer of the Miyun Reservoir Management Office of Beijing once again deeply aware of the responsibilities and mission of the water workers in the capital, especially as a "priceless treasure" Miyun Reservoir project operation and management worker.
talks about the changes in the "priceless treasure" of Miyun Reservoir in recent years, and there are countless stories about the number of changes in the weekly ladder. For example, the reservoir water storage capacity has been rising continuously. On July 20, 2021, the reservoir water level returned to 150.00 meters after 22 years. On October 1, the water level of the reservoir reached 155.30 meters, and the corresponding water storage capacity was 3.5793 billion cubic meters, setting a new record of water storage since the construction of the Miyun Reservoir. "As the capital's combat water source, this is an important historical moment. Therefore, on October 7 this year, we also set up a new water level monument. The original 153.98-meter highest water level monument was moved to the Miyun Reservoir Exhibition Hall to be preserved as important historical data."
For Zhou Shangti, the water storage capacity of Miyun Reservoir has hit historical highs and high water level operation has become the norm, which also means that his work faces new challenges. "It is to lay a good foundation for operation and management, strengthen the "cage" for engineering safety, blaze the "path" for innovative development, and ensure the safety of the high water level operation project of Miyun Reservoir more comprehensively and efficiently." Zhou Shangti said.
According to Zhou Shangti, this year, the Miyun Reservoir Management Office has established a dynamic adjustment mechanism for safety monitoring of high water levels, divided the flood season and non-flood season. According to different characteristics of water levels such as flood limit water level, historical highest water level, and designed water level, dynamic adjustment of work situation monitoring will be implemented, further optimize and refine the frequency, content and requirements of project inspection and work situation monitoring and analysis, and streamline the inspection, analysis, reporting and disposal procedures. This not only meets the needs of daily management, but also ensures the safety of high water level operation of reservoir projects.
weekly recalled that at the review meeting of the "Miyun Reservoir High Water Level Operation Safety Analysis Report" on June 30 this year, senior professors and technical experts from Tsinghua University , China Water Resources and Hydropower Research Institute , Beijing Water Affairs Bureau and other institutions gave a thumbs up to the people of Miyun Reservoir, "The thumb is to give us this safety analysis report of nearly 40,000 words vertically. The report integrates the Miyun Reservoir project's initial construction, previous safety inspections, earthquake re-examination, safety appraisal, hazard removal and reinforcement status, and the current status of project operation and management. It conducts a comprehensive analysis and judgment from the aspects of engineering properties, high water level situations, risks and hidden dangers. The conclusion shows that the overall safety structure of the Miyun Reservoir is safe and the operation risks are basically controllable."
Innovation-driven development. The report pointed out that we must "comprehensively promote the great rejuvenation of the Chinese nation with Chinese modernization." This year, the Miyun Reservoir Management Office has also steadily promoted the research and demonstration projects of key technologies for reservoir dam safety monitoring, early warning and health diagnosis on the basis of the 2021 Zoumazhuang sub-dam pilot, and actively introduced new safety monitoring technologies and new means of industrial analysis such as Beidou remote sensing, micro-core piles, and made every effort to improve technical support and guarantee capabilities. "In the near future, Miyun Reservoir will form a reservoir supervision system that integrates space, earth and water: in space, satellites can be used to combine remote sensing, micro-core piles and other technologies to monitor remotely; at low altitude, drones can be used to take aerial photos; on the ground, monitoring instruments such as seepage, deformation, and cracks are arranged; on the water surface, unmanned ship sonar measures the terrain and silt of the reservoir area, and underwater robots can see the appearance of dam slopes and tunnels. "Zhou Shangdi is very much looking forward to such a Miyun Reservoir, " Do my best to protect this basin of clean water."
week climbed the ladder and said, "When I retire, I must write down the 'past and present life' of every main and secondary dam of Miyun Reservoir, every spillway , and every tunnel. Although buildings can't speak, I want to use my years of understanding of them and use my words to let everyone talk to them."
