Core Viewpoint - The Jinan High-tech East District Yunba project has entered the empty load trial operation phase, with significant progress in construction and the removal of construction barriers, enhancing urban traffic flow for citizens [1][3]. Group 1: Project Overview - The Yunba project is a key public transportation initiative in Jinan, emphasizing the principles of "convenience for the public, benefits for the people, and minimal disruption" during construction [3]. - The project has successfully removed over 465,000 square meters of construction barriers, allowing urban roads to gradually "return" and improving travel for citizens [1]. Group 2: Construction Strategies - To minimize disruption, the project team has implemented various strategies, including optimizing designs to relocate construction areas and compressing barriers to reduce their impact on traffic [3][8]. - A significant adjustment was made by moving the construction line south to utilize the roadside green belt, avoiding the closure of nearly 6 kilometers of motor vehicle lanes and all non-motor vehicle lanes [7]. Group 3: Efficiency Improvements - The project team has compressed the distance between barrier isolation piers and foundation pits to just 20 centimeters in the critical area of Tangye Road to maximize space for public use, resulting in a total barrier reduction of 23,000 square meters [10]. - In Spring Garden Road, the construction barriers reduced a four-lane road to two lanes, but through optimized pile foundation design and prefabrication of rebar cages, the team completed the work in just 40 days, significantly improving construction efficiency [11]. Group 4: Broader Impact - The Yunba line not only represents the speed of urban development but also reflects the commitment to serving the public, with every space saved and time reclaimed contributing to the city's warmth [19]. - Other projects, such as the Jinan Metro Line 4 and Line 6, are also progressing with barrier removal, promising further improvements in urban traffic flow and citizen travel experience [21].
