北京二道河水库开工建设 预计2030年底完成主体建设

Core Viewpoint - The construction of the Erdao River Reservoir is a critical project aimed at enhancing flood control capabilities in the southwestern region of Beijing, with a total capacity of 76.32 million cubic meters and expected completion by the end of 2030 [1][2]. Group 1: Project Overview - The Erdao River Reservoir is located in the upper reaches of the Dashi River basin, with the main dam being the first roller-compacted concrete gravity dam in Beijing, standing at 100 meters high, making it the tallest dam in the city [1][2]. - The reservoir is designed to reduce the historical maximum flood peak of 5,300 cubic meters per second, effectively controlling 75% of the mountainous watershed area of the Dashi River [2]. Group 2: Construction and Technology - The project will utilize advanced technologies such as intelligent compaction and temperature control to ensure high construction quality, and a digital twin platform will be established for more scientific and intelligent management of the reservoir post-commissioning [2]. - The construction tasks include road relocation, earthwork excavation, and concrete pouring, with a focus on adhering to the overall progress plan and key timelines to ensure the reservoir is operational by the end of 2030 [2]. Group 3: Flood Control Significance - Historically, the Dashi River basin has faced frequent flooding, with significant events recorded in 2012 and 2023, highlighting the urgent need for effective flood control measures [1]. - The completion of the Erdao River Reservoir is expected to significantly enhance flood safety in the southwestern part of the capital, providing a robust barrier against upstream floodwaters [2].
