顶管遇现状运行管道时的一种解决方法

A Solution for Pipe Jacking When It Encounters A Current Pipe

针对顶管顶进线路上遇到现状运行管道的问题,以工程实例为例,提出了一种“8”字形逆作法的解决方案,既解决了顶管跨越障碍的问题,又保障了现状管道的运行安全。

Aiming at the problem of encountering current operating pipelines on the top pipe jacking line,taking engi⁃neering examples as an example,a"8"-shaped reverse method solution is proposed,which not only solves the problem of crossing obstacles by the top pipe,but also ensures the safe operation of the current pipeline.
