【Abstract】:Aiming at the problem of encountering current operating pipelines on the top pipe jacking line, taking engineering 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.

【Key words】:pipe jacking;current working line;inverse method
