Device for installation of conduit for streaming surface water through concrete barrier for traffic lane, in highway, has ring forming unit for performing force of displacement on molding form in longitudinal direction

摘要

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.
