MACHINE FOR PRODUCTION OF CONCRETE PIPES AND METHODS OF PRODUCTION OF SUCH PIPES AND CONCRETE Russian patent published in 2006 - IPC B28B21/26 

FIELD: construction industry; methods and devices for production of concrete pipes and the concrete for the pipes production.

SUBSTANCE: the invention is pertaining to the field of construction industry, to the methods and devices for production of concrete pipes and the concrete for the pipes production. The invention presents the machine for production of the concrete pipes having a sealing head consisting of a roller head and a long bottom part. At that the roller head and the long bottom part may be quickly mounted on a means making the sealing head in motion and to dismantle it from this means as a single whole with the help of one fastener, and to conduct their final adjustment outside the machine. At that the means making the sealing head in motion does not hinder the stream of green concrete to move to the area of the concrete consolidation, and the ratio of speeds of the roller head and the long bottom part may be smoothly varied, and the easily replaceable protective wear-resistant rings serve for a prevention of deformation of the constant components of the machine caused by erosion as a result of the unwanted penetration of the green concrete into the long bottom part. The technical result is a raise of productivity and expansion of the range of dimensions of the produced pipes.

EFFECT: the invention ensures an increased of productivity and expansion of the range of dimensions of the produced pipes.
