CNCEC(SH:601117) Zhong Guo Xin Wen Wang·2026-01-06 07:58Core Viewpoint - The successful completion of the second DN1200 large-diameter heating pipeline in Shanxi's coal-to-clean energy project marks a significant achievement in overcoming complex geological challenges and inter-departmental coordination, contributing to the region's clean heating and ecological development goals [1][5]. Group 1: Project Challenges and Solutions - The second pipeline construction faced increased difficulty due to complex geological conditions, including "soft above, hard below" strata, which posed significant challenges to the accuracy and safety of the pipeline installation [1]. - The project required coordination among multiple departments, including power, water, and transportation, with any delays potentially halting the entire project [1]. - A specialized task force was established to enhance inter-departmental communication and address core issues such as high-voltage protection and irrigation guarantees, successfully navigating bureaucratic hurdles [4]. Group 2: Construction Strategies and Execution - To minimize the impact on agricultural production and local residents, critical construction processes were confined to a limited "construction window," necessitating precise and efficient coordination [3]. - The construction team employed a scientific strategy of "slow rotation, low drilling pressure, and frequent cleaning" to manage the complex geological challenges effectively [3]. - The project utilized advanced construction equipment and a highly experienced team, implementing a 24-hour operation schedule to ensure safety and quality standards were met throughout the welding and inspection processes [4]. Group 3: Societal Impact and Development Goals - The successful crossing of the two heating pipelines not only facilitates the heating supply in the Shangdang District but also supports the broader goal of achieving clean heating and environmental protection in the region [5]. - The project is a key initiative for Shanxi's ecological and social development, addressing winter heating challenges while promoting green development and rural revitalization [5]. - The collaboration and technical expertise demonstrated in this project reflect a commitment to prioritizing public welfare and driving high-quality development in the province [5].
