中俄东线连通工程冲刺“最后百米”

Core Viewpoint - The construction of the China-Russia East Line connection project in Shenyang is crucial for enhancing energy security in the region, with the project nearing completion and set to be operational by the end of February [1][2]. Group 1: Project Overview - The China-Russia East Line connection project involves the construction of a 7.9-kilometer DN300 natural gas pipeline with a design pressure of 4.0 MPa, aimed at providing a stable and efficient gas supply to Shenyang [1]. - As of now, 7.8 kilometers of the pipeline have been laid, achieving an overall progress of 98.7%, indicating that the project has entered the final sprint phase [2]. Group 2: Construction Challenges and Innovations - The project team has faced significant challenges due to winter construction conditions but has successfully optimized processes to complete preliminary work in just 20 days [2]. - Innovative technologies have been implemented, including solar-powered smart warning bands that provide real-time pipeline status updates and an epoxy glass fiber protective layer to enhance corrosion resistance and physical damage protection in low-temperature environments [2]. Group 3: Workforce and Morale - Despite harsh weather conditions, the construction site operates efficiently, with workers maintaining high-quality standards in welding and machinery operation [2]. - The project manager expressed a strong commitment to delivering natural gas to households, emphasizing the team's dedication despite the cold and challenging work environment [2].
