Process for laying a railroad-subway superstructure without ballast and apparatus for producing said superstructure.

摘要

The process for laying a railroad-subway superstructure without ballast consists in designing prefabricated components which, once assembled in a line, allow to build railroad routes with a precision in the range of one millimeter without having to perform any adaptation work. The apparatus for producing the superstructure comprises at least one concrete-mixing system (2), at least one casting line (3) defined by a plurality of mutually aligned and independent forms (4), at least one preparation lane (25) for the transverse compression of the platforms (7) and their advancement for sequentially performing completion and checkout operations on them, and means (30) for storing the platforms (7). <IMAGE>
