油气输送管道顶管穿越公路施工设计

顶管穿越施工是在穿越铁路、高速公路、河流、建筑物等障碍物，或在城市公路主要干道路面下铺设时，常采用的一种特殊施工方法。它可以不拆除或少拆除地面障碍物，不中断地面交通；在穿越河流时既不影响正常通航，也不需要修建围堰或进行水下作业。文章介绍了顶管穿越施工前期准备以及顶管施工方法，针对顶管施工的质量保证和安全提出了相应的措施。

The Design of Jacking Pipe Crossing Highway in Construction of Oil & Gas Pipelines

The construction of the jacking pipe through the railways、highways、fivers、buildings and other obstacles, or the laying of the main roads of the urban road pavement, oiten be used as a special construction method. It can be used without or less removal of ground obstacles, without interrupting the ground transportation; neither affecting normal navigation through the fiver, without building cofferdams or underwater operations, The article describes the preparation of construction of the jacking pipe and the method for jacking pipe construction, it also proposals the corresponding measures to protect the quality assurance and safety of the construction.
