打造“平急两用”滨水空间，永定河卢三段综合提升工程主体完工

Core Viewpoint - The Yongding River Lusan Section Comprehensive Improvement Project has recently completed its main structure, significantly enhancing flood control capabilities and creating a new leisure landmark for citizens [1][3]. Group 1: Project Overview - The project is part of the Haihe "23·7" flood disaster recovery and reconstruction efforts, featuring the construction of underground reinforced concrete anti-erosion walls to improve flood protection on the left bank of the Yongding River [1][3]. - The Yongding River Lusan Section, which stretches 17.4 kilometers from Sanjiadian to Lugou Bridge, has not been reinforced since 1983, indicating a significant need for upgrades due to aging infrastructure [3][9]. - The improvements will enable the levee to withstand floods of up to 16,000 cubic meters per second, greatly enhancing flood safety levels on the left bank [3][9]. Group 2: Innovative Features - The project includes the innovative development of a vertical protective structure for the anti-erosion wall, which is 0.8 meters thick and designed to shield the levee from high-velocity water flow [5]. - The design incorporates a "dual-use" concept, allowing the levee top to serve both as a flood response route and a recreational space for the public [5]. Group 3: Community Impact - The area has transformed into a popular leisure destination, with the Shougang Park section attracting up to 10,000 visitors daily since its opening [6][8]. - Future plans include expanding the recreational space to 60,000 square meters for winter activities and enhancing family-friendly features [8]. - The project emphasizes historical preservation, integrating elements like the historical irrigation canal into the design [8]. Group 4: Future Developments - A 9-kilometer pedestrian path along the Yongding River is planned to connect various parks and scenic spots, enhancing public access to the river [9]. - The overall progress of the Yongding River Lusan Section Comprehensive Improvement Project has reached 80%, with full completion expected by April 2026 [9].
