ASCENDING PIPE FOR GUIDING THICK SUBSTANCES

摘要

One or more coupled pipes (14) forming the liquid concrete supply line, are supported by a fixed mounting. Further pipes (14) can be moved axially in guides (26) fixed to the construction. The lowest pipe is supported in a fixed mounting, the remainder above, are held in guides (26). The guide comprises two adjacent components (30) forming an opening (32) for the pipe. It includes sliding components (34) resting against the pipe in the opening. A lifting collar for raising the pipeline, is also claimed.
