Focus on research and solve the six major technical problems

As a national major water conservancy project with the largest water traffic flow, the longest water traffic line, the most complicated construction conditions, and the highest total investment in Guangdong Province so far, the construction of the Guangdong Water Resources Configuration Project on Beibu Gulf will face at least six major industries and even the world -class level. Difficulties and challenges. What are 6 major technical points? How does relevant units overcome?

It is understood that the project faces the six major problems: one is the construction and joint dispatch of Jiangku Water Network under the condition of complex water conditions, and the other is the geological survey and research of multi -phase complex erosion in the cloud land. The research and design of the lining structure of high hydraulic tunnels under hydrogeological conditions, fourth, is the development and construction of long -distance deep -buried tunnel multi -function TBM under the condition of complex geological conditions. Intelligent operation and maintenance and guarantee of buried pipelines.

Liu Yuanxun, chief engineer of the North Engineering Project Design, said that these are issues that need to be studied and solved in engineering planning and construction.

Through Xijiang Water Pump Station, Waterwater Line, etc., the large and medium -sized reservoirs such as Xijiang, Gaozhou, Heidi, and other large and medium -sized reservoirs have established a large -scale complex water network system covering the 13 districts and counties of 4 cities in western Guangdong. In the huge water network system, there are time and space differences in rainfall and runoff in the water area and water area. In the face of complex water conditions, how to improve the water supply guarantee in water areas, how to deploy outer water and storage reservoir to achieve water resources time and space The balanced goal needs to start a large -scale, cross -ride networking joint scheduling research to achieve efficient optimization of water resources.

The water flow line of the north project is about 499.9 kilometers long, and the largest hole diameter of the tunnel is 8.2 meters. The cloud -open plot and the coastal plain with complex geological and hydropological conditions along the line are prominent. The product with the inner diameter of the pipeline) reached 1420, which is the highest long -distance large -diameter water transfer project in China. There are very few cases of similar projects at home and abroad. How to control the development of tunnels during the operation period is developed by internal fracture and prevent internal water seepage. Related research.

"In response to the key difficulties of design, construction, and operation and maintenance, we rely on scientific and technological innovation, focus on scientific research on major technical problems, fully demonstrate, and compile the" Outline of the Scientific Research Research on Water Resources Configuration Engineering of the Beibu Gulf ". With the comprehensive development of scientific research topics, it will lay a solid foundation for project construction.

Yuehai Group organized in -depth study and exchanges in large -scale projects across the country, conducted field survey projects, and continued to optimize design plans; multi -party consultation professional opinions, and made technical reserves and construction organizations.

On June 28, 2020, the Guangdong Provincial Department of Water Resources issued the preliminary work plan for accelerating the promotion of the Guangdong water resources allocation project around Beibu Gulf to compact various goals and tasks. In order to solve engineering technical problems, the project selected scientific research institutes and well -known universities through public bidding methods to conduct scientific research from 6 categories and 21 items. Yuehai Group organizes the expert technical team to investigate and exchange the engineering trunk lines and division of engineering engineering lines.

Zhongshui and Pearl River -Guangdong Water Conservancy Power Design Institute invested more than 600 people teams. The charts were fighting, and the implementation of various tasks was promoted day and night. "Guangdong Speed". In response to the key difficulties of design, construction, and operation and maintenance, the design team relied on scientific and technological innovation to compile the "Outline of the Scientific Research Research on the Configuration Engineering of Water Resources Configuration in Beibu Gulf" to escort the engineering design plan and construction management.

At present, the relevant scientific research work of engineering construction has been fully launched, focusing on scientific research on major technical problems. For example, Xijiang takes a water flow of 110 cubic meters per second, 162 meters, the single pump design flows 22 cubic meters per second, and the single pump power is 48 MW.

The water pouring trunk line Yunkai Mountain Tunnel is 64.48 kilometers long and the maximum buried depth of 910 meters is the longest and deepest water tunnel tunnel in Guangdong. Bad geological issues such as wide breaks, tunnel lining structure design, tunnel multi -function TBM development and construction facing large challenges.
