Method and apparatus for the production of tubes from concrete mix

摘要

The invention concerns a procedure for the production of tubes from concrete mix, whereby the concrete mix is filled into a shaping device, for the purpose of shaping, where it is condensed with a tool. The invention should enable an effective and fast production of concrete tubes with high quality regarding the uniformity of the material characteristics. In such a procedure the concrete mix is condensed in an interspace between two parts of a tool that rotate relative to each other.
