(The construction site of Lot B3 of Pearl River Delta Water Resources Allocation Project.) New era, new journey, new great cause The early winter of South Guangdong is in the golden age of water conservancy construction. By the Shiziyang River, at the beginning of Chaoyang, we entered the working well from the Dongguan side of the Nansha Bridge and entered the construction site of Lot B3 of the Guangdong Hydropower Pearl River Delta Water Resources Allocation Project, which is nearly 60 meters under the Shiziyang River. In the tunnel about 8 meters wide, many sets of steel bar trolleys and needle beam steel formwork trolleys roared. The builders were busy working around various equipment, and the construction of the project was accelerating. Zhanjiang Xuwen Liyutan Reservoir is a 1400 mu Guangdong Hydropower "fish and light complementary" project. Rows of photovoltaic panels on the water surface are arranged in a matrix form. Migratory birds fly by from time to time in the air, creating a new picture of green countryside. By the end of 2021, the cumulative on grid energy of photovoltaic power generation of the project will reach 560 million kilowatt hours, injecting a steady stream of green power into rural revitalization in Guangdong. The report of the 20th National Congress of the Communist Party of China proposed to optimize the layout, structure, function and system integration of infrastructure and build a modern infrastructure system. "At present, large projects and projects are under construction, and infrastructure construction has become an important support to promote high-quality economic and social development." Cai Yong, deputy general manager of Guangdong Hydropower, introduced that, starting from taking root in Guangdong's traditional water conservancy projects, to major inter basin water transfer projects, and to clean energy power generation projects distributed across the province and across the country, Guangdong Hydropower accelerated its transformation and achieved continuous growth in the struggle and practice of one big project after another. "We hope to always adhere to technological innovation, focus on major projects and projects, and strive to be the backbone of Chinese path to modernization." New technology and new process create new construction record?? The accelerated construction of the Pearl River Delta Water Resources Allocation Project "In the past November, the single month concrete pouring for the DG22 # - GZ21 # interval lining construction of our project exceeded 321 meters, creating the fastest single month record for the prestressed concrete lining construction of the Pearl River Delta Water Resources Allocation Project." Rong Jiecheng, secretary of the Party branch of the B3 bid project, said that as the first bid section of the whole line to realize the flow process of prestressed concrete lining construction, it represents that the lining construction of the whole project has pressed the "fast forward key" and is accelerating towards the goal of opening water by the end of 2023. As a major national water conservancy project and an important livelihood project in the Guangdong Hong Kong Macao Greater Bay Area, the Pearl River Delta Water Resources Allocation Project passes through the core urban agglomeration of the Pearl River Delta by means of deep pipeline. After completion, it will realize water supply from the West River to the eastern part of the Pearl River Delta, solve the problem of water shortage in living production in Guangzhou, Shenzhen and Dongguan, and provide emergency standby water sources for Hong Kong and other places, providing water resources guarantee and strategic support for the development of the Guangdong Hong Kong Macao Greater Bay Area. At present, Guangdong is speeding up the construction of the "five vertical and five horizontal" water resources allocation backbone network to solve the problem of uneven spatial and temporal distribution of water resources in the province. Since the 1950s, looking down on the land of South Guangdong, from Liuxi River Hydropower Station, Dongshen Water Supply Project, to Pearl River Delta Water Resources Allocation Project... Guangdong Hydropower has undertaken many major water conservancy infrastructure construction projects in Guangdong, linked up Guangdong's powerful water resources network, and provided strong water conservancy support for the economic and social development of Guangdong. With the continuous improvement of project scale and difficulty, technological innovation has become a major project
