国内首例！石热入济新进展，济南今冬天更蓝

Core Viewpoint - The successful completion of the first domestic pipeline load-bearing rotating bridge marks a significant milestone for the Shihe-Ru-Jinan project, which aims to provide stable and clean heating sources to Jinan, enhancing energy structure transformation towards green and low-carbon solutions [1][12]. Project Overview - The Shihe-Ru-Jinan project is a key livelihood and environmental initiative in Jinan, expected to introduce tens of millions of square meters of stable clean heating from the Tai'an Shihong Thermal Power Plant annually, effectively replacing numerous scattered coal-fired boilers in the urban area [1][12]. - The project will significantly improve heating security in the western urban area of Jinan and is projected to reduce carbon dioxide emissions by tens of thousands of tons each year, contributing to better air quality and supporting carbon neutrality goals [12]. Technical Achievements - The bridge, weighing 14,000 tons and measuring 150 meters in length and 17 meters in width, was rotated 90 degrees with millimeter-level precision, overcoming significant technical challenges in a high-density railway area [4][5]. - The project team utilized a novel "pipeline load balance rotation" construction technique, which is the first of its kind in the domestic long-distance heating sector, allowing for simultaneous installation and welding of heating pipelines during the bridge's construction [4][5]. Safety Measures - The construction took place adjacent to the busy Beijing-Shanghai Railway, necessitating stringent safety protocols to ensure zero accidents during the project [8][9]. - The project team implemented a comprehensive safety management system, including real-time monitoring and various safety measures, to protect both railway operations and construction activities [9].
