Core Viewpoint - The successful commissioning of the middle section of the West-to-East Gas Pipeline (from Zhongwei to Zao Yang) is a significant milestone in China's energy infrastructure, enhancing natural gas distribution across key economic regions and optimizing energy delivery structures [1][3]. Group 1: Project Overview - The Zhongwei to Zao Yang section of the West-to-East Gas Pipeline spans 1,235 kilometers, passing through five provinces, and has a designed annual gas transmission capacity of 25 billion cubic meters [3]. - The pipeline is designed to alleviate the high load operation of the first and second lines of the West-to-East Gas Pipeline, facilitating increased gas output from western oil and gas fields to meet the demand in central and eastern China [3]. Group 2: Engineering and Technology - The project features complex terrain, including the Qinling Mountains, with 311 kilometers of the pipeline requiring 105 mountain tunnels, showcasing advanced construction techniques such as the use of a full-face hard rock tunnel boring machine [5]. - The application of the Beidou satellite geological disaster monitoring system provides early warning for geological risks, ensuring high-quality and safe construction practices [5]. Group 3: Environmental Considerations - The project adheres to green development principles, optimizing route selection to minimize ecological impact, including the use of shield tunneling under the Wei River and deep foundation pit techniques in sensitive areas [7]. - The pipeline incorporates solar power generation systems with a total capacity of 2,200 kilowatts, leading to significant reductions in carbon emissions and energy consumption [7]. Group 4: Technological Innovation - The National Pipeline Network Group emphasizes technological innovation and domestic equipment manufacturing, achieving breakthroughs in key equipment for gas transmission [9]. - The project has implemented digital design, standardized construction, and intelligent management to enhance efficiency and performance [9].
