重大水利工程新突破！

Core Viewpoint - The Dianzhong Water Diversion Project has made significant progress with the successful construction of the Qujiang inverted siphon, marking a breakthrough in this major national water conservancy project [1][2]. Group 1: Project Overview - The Qujiang inverted siphon is located in the Water Tank Village of Gaoda Township, Tonghai County, Yuxi City, and spans approximately 1829 meters, intersecting multiple transportation routes and rivers [2]. - The project is part of the largest water diversion project under construction in China, covering a total length of 664.326 kilometers, including 611 kilometers of water diversion tunnels [3][5]. Group 2: Technical Challenges and Innovations - The construction team faced challenges such as high precision requirements for road subsidence control, complex underground pipelines, and strict ecological protection standards [2]. - Innovative techniques such as refined detection, three-dimensional pipeline positioning, and ecological isolation were employed to control roadbed subsidence within 3 millimeters while ensuring the safety of the ecological environment and pipelines [2]. Group 3: Expected Impact - Upon completion, the project is expected to achieve an annual water diversion volume of 340 million cubic meters, effectively alleviating water scarcity issues in the central Yunnan region and benefiting over 11 million people along the route [5].
