Abstract (en)
[origin: EP2369130A1] The method involves separating pipes and/or pipelines (16) e.g. district heating pipeline, from anchoring sections (10) and projecting suspensions in the tunnel sections. Pipe pieces (36) of small diameter are slided with respect to the tunnel sections in a rail laid in the tunnel sections. The pipes and/or the pipelines are slided in a support (20) arranged in the pipe pieces until an entire pipe section is lined with opposite pipe pieces. Gaps formed between the pipe pieces and the tunnel sections are filled with filling material (34). An independent claim is also included for a system for cleaning tunnel sections comprising a pipe piece with small diameter than tunnel sections.
