二道河水库开工建设

Core Viewpoint - The construction of the Erdao River Reservoir in Fangshan District is a significant project aimed at enhancing flood control capabilities in the Dashi River basin, with the reservoir expected to be completed by the end of 2030 [1][2]. Group 1: Project Overview - The Erdao River Reservoir will be the highest dam in Beijing, with a total storage capacity of 76.32 million cubic meters, and is classified as a medium-sized reservoir [1]. - The main dam will be a roller-compacted concrete gravity dam, standing at 100 meters high, and will primarily focus on flood control [1][2]. - The project will utilize advanced technologies such as intelligent compaction and temperature control, aiming to create an intelligent and eco-friendly dam [2]. Group 2: Flood Control Capabilities - Once completed, the reservoir will effectively control 75% of the mountainous watershed area of the Dashi River, designed to withstand a maximum flood flow of 5,300 cubic meters per second, which is equivalent to the highest recorded flood peak [2]. - The construction is part of a broader initiative to enhance the flood control infrastructure in the region, including other major water conservancy projects [2].
