津潍高铁迎来重大节点，东营南站德大线恢复开通

Core Viewpoint - The successful reopening of the De-Da Line at Dongying South Station, constructed by China Railway Construction Corporation, is a significant milestone for the Tianwei High-Speed Railway project, enhancing regional transportation networks and improving transport efficiency [1]. Group 1: Project Details - The newly built Dongying South Station features an elevated station design, spanning the De-Da Line, Huang-Da Line, and Tianwei Line, and has a total construction area of 74,120 square meters, with the station building covering 39,996 square meters [6][14]. - The station consists of two underground levels and four above-ground levels, with a scale of 7 platforms and 20 tracks, designed as a "line-side + elevated" waiting area [14]. Group 2: Construction Challenges and Solutions - The construction faced challenges such as heavy workload, tight timelines, and interference with operational lines, prompting the project team to implement various measures to address the complex construction environment [6]. - Measures included the use of steel protective canopies for full enclosure at De-Da Station, the establishment of a "smart construction site" system for simulation and optimization, graded progress control, emergency material reserves, and a technical task force employing expert consultations and on-site testing to resolve technical issues [6]. Group 3: Strategic Importance - The Tianwei High-Speed Railway is a crucial part of the national "Eight Vertical and Eight Horizontal" high-speed rail network and serves as an auxiliary corridor to the Beijing-Shanghai High-Speed Railway, aimed at strengthening transportation links between Beijing, Tianjin, and the Shandong Peninsula, as well as the Yangtze River Delta region [14].
