<p>The device (10) has a ring (12) forming a unit for performing a force of displacement on a molding form (11) in a longitudinal direction. The ring is arranged at a longitudinal end of the molding form, and slightly projects with respect to the longitudinal end. The molding form is used for molding a conduit using a non-concrete material. The molding form includes a box structure with longitudinal side walls and end side walls closing the longitudinal end and another longitudinal end of the molding form, contiguous to a top wall. The non-concrete material is provided with complex thermoplastic composite material layers. An independent claim is also included for a method for installation of a conduit of drainage duct of streaming through concrete barrier for lane.</p> |
