3万公里燃气管网将持续“焕新”

Core Viewpoint - The article emphasizes the urgent need for a nationwide overhaul of urban underground pipelines, particularly gas pipelines, which have become a systemic risk due to aging infrastructure and safety concerns [3][5][12]. Group 1: Current Situation and Challenges - The Ministry of Housing and Urban-Rural Development has set a target to complete the renovation of 30,000 kilometers of various gas pipelines by 2026, with an investment of approximately 220 billion yuan allocated for major projects, including urban underground pipelines [3][5]. - Aging pipelines, many installed in the 1980s and 1990s, pose significant public safety risks, with issues such as gas leaks from corroded pipes accounting for 78% of repair requests in some areas [5][6]. - The complexity of urban environments, including the presence of multiple underground utilities and the need to minimize disruption to residents and traffic, complicates the renovation process [9][10]. Group 2: Strategic Actions and Innovations - The renovation of underground pipelines has been elevated to a national strategic initiative, integrating it into broader safety and infrastructure development plans [6][7]. - Innovative approaches, such as "one road one policy" and "one night one policy," are being implemented to reduce disturbances during construction, alongside the use of advanced technologies for monitoring and data collection [12][13]. - A multi-faceted funding mechanism is being proposed, combining central subsidies, local contributions, and user fees to address the financial challenges faced by gas companies in undertaking these renovations [12][13]. Group 3: Long-term Goals and Vision - The ultimate goal of the pipeline renovation initiative is to embed resilience thinking into the entire lifecycle of urban planning, design, construction, and management, enabling cities to better handle uncertainties and risks [13]. - The completion of the 30,000-kilometer renovation target is seen as a significant milestone, but it is only the beginning of a broader effort to ensure the safety and reliability of urban infrastructure [13].
