从长输管道穿越工程发展经验看,穿越技术已经从传统的裸露、管沟埋设等方式向定向钻、隧道等方式发展。长输管道穿越有必要根据现场地质条件、施工条件等选择施工技术、确定穿越方案并签订穿越协议。英国长输管道穿越协议涵盖了穿越工程实施方案、程序、基本要求及后续额外工程有关各方的权利义务关系。从协议内 From the experience of long-distance pipeline crossing engineering development, the crossing technology has been developed from the traditional methods such as bare exposure and buried trench management to directional drilling and tunneling. It is necessary to choose the construction technology according to the on-site geological conditions and construction conditions, and determine the crossing plan and sign the crossing agreement. The British long-distance pipeline crossing agreement covers the rights and obligations of all parties involved in the crossing of the project implementation plan, procedures, basic requirements and subsequent additional works.
