项目背景隧道施工在整个工程施工中安全隐患是最多的,防范也是最难的,尤其是高瓦斯隧道施工。为确保瓦斯隧道的施工安全,负责承建成贵铁路13标工程的中铁十五局集团以落实成贵铁路公司《高瓦斯隧道施工安全管理办法和管理专项制度》及瓦斯隧道管理清单为主线,不断完善高瓦斯隧道管理组织机构,细化高瓦斯隧道施工安全管理实施细则,构造严密可靠的安全防护网,确保隧道施工安全。新建铁路成都至贵阳线乐山至贵阳段,西起四川省乐山市,乐山(含)至贵阳东(不含)正线全长515.02 km,站前工程13标由中铁十五局集团承建,共有隧道8
Background of the Project Tunnel construction has the most potential safety hazards in the entire project construction. It is also the most difficult prevention measure, especially for the construction of high-gas tunnels. In order to ensure the safety of the construction of the gas tunnel, the 15th China Railway Group Corporation responsible for the construction of the 13 superstructure of Chengdu-Guizhou Railway has been implementing the “GAC Tunnel Construction Safety Management Measures and Management System” and the gas tunnel management list as the main lines Improve the organization and management of high-gas tunnels and refine the implementation rules for the construction safety management of high-gas tunnels so as to construct a tight and reliable safety net to ensure the construction safety of the tunnels. From the Leshan to Leshan, Leshan (inclusive) to the west of Guiyang (excluding) the total length of the main line is 515.02 km from the Leshan to Guiyang section of the railway from Chengdu to Guiyang in the west, and 13 to be completed by the 15th Bureau of China Railway Group Corporation Tunnel 8
