Core Viewpoint - The successful completion of the rotation construction of the overpass bridge on the Dongliang Expressway marks a significant breakthrough in the project, which is crucial for enhancing regional industrial cooperation and cultural tourism exchange in Shandong Province [1][4]. Group 1: Project Details - The overpass bridge is a double-cantilever cable-stayed bridge with spans of 80 meters and 100 meters, and a total rotation length of 177 meters, requiring a counterclockwise rotation of 67.4 degrees [4]. - The bridge weighs 25,000 tons, equivalent to the weight of 20,000 ordinary cars, and is located just 12.9 meters from the nearest railway fence, necessitating high safety standards during construction [1][4]. Group 2: Technological Implementation - The project utilized BIM technology to create a three-dimensional model, allowing for precise predictions of stress points and posture changes during construction [4]. - A BeiDou real-time monitoring system was employed to achieve millimeter-level precision in the completion of the bridge's rotation and alignment [4]. Group 3: Project Significance - The Dongliang Expressway's Shenxin section spans 197.108 kilometers and is designed with a dual four-lane standard, with a planned speed of 120 kilometers per hour [4]. - The completion of this project is expected to significantly promote industrial cooperation and cultural tourism exchanges along the route [4].

Core Points - The completion of the key control project, the turning construction of the overpass bridge over the Wari Railway, marks a significant milestone for the Dongliang Expressway, which is invested by Shandong Highway Group and constructed by China Railway 14th Bureau [1][3] Group 1: Project Overview - The Dongliang Expressway, specifically the section from Shenhai to Xintai, has successfully completed a critical engineering task with the overpass bridge construction [1][3] - The bridge is located close to the operational line of the Wari Railway, with the nearest edge of the bridge being only 12.9 meters from the railway fence, presenting dual challenges in safety management and construction organization [3] Group 2: Construction Techniques - The project utilized advanced construction techniques, including the seventh-generation dual-side dual-direction anti-slip cable system, which extends the lifespan of the stay cables and ensures the quality of the bridge [3] - BIM technology was employed to create a three-dimensional model for simulating the entire turning process, allowing for precise predictions of stress points and posture changes [3] Group 3: Project Significance - Once completed, the Dongliang Expressway will span a total length of 197.108 kilometers, featuring a dual four-lane standard and a design speed of 120 kilometers per hour, enhancing connectivity between the eastern coastal region and the central-western region of Shandong Province [5] - The expressway is expected to facilitate the timely delivery of fresh seafood and local agricultural products, as well as promote tourism in the Yimeng region, thereby fostering deeper industrial cooperation and cultural exchanges among cities along the route [5]
