  • the object underlying the invention is also achieved by a method for the production of a multi-layer, in particular two-layer concrete pipe solved, which has the following steps: first, essentially one vertically standing molded jacket swung into a stand and the molded jacket with a first concrete mix from a first loading system filled. This first concrete mix is then in the form jacket distributed by a rotating and vertically movable compaction tool and compacted, and possibly smoothed the inner surface. Before demoulding the Concrete pipe becomes a second concrete mix by means of a second loading system filled into the essentially vertically standing molded jacket.

  • This invention The process is characterized by the fact that neither a change of the compacting tool a transport of the outer part of the multilayer Tube together with the molded jacket in another stand is required. Rather, the compaction tool itself can be inserted the second concrete mix within the shell in size to be changed.
