Abstract:
1. A culvert with a deformation zone consisting of prefabricated components arranged in a road ditch the culvert comprising at least one fixed basic component and at least one deformation component sliding in the basic component in the direction of the longitudinal culvert axis and covered by a deformable decking or backfilling or by a cover, wherein the basic component of the culvert is formed by a set of prefabricated concrete or reinforced concrete beds of a “V”-shape comprising two shoulders, the beds being placed adjacent to each other on a concrete foundation in the road ditch so that the shoulders of the beds abut to the ditch walls, and the upper part of both shoulders of each bed is fitted with opposing guiding recesses for arrangement of deformation components formed by a set of at least two lateral rigid girders arranged slidingly in the guiding recesses, wherein the girders are slidable in the direction of the longitudinal ditch axis, wherein there are deformation gaps between the lateral girders and, at least on one front of the culvert at least one additional deformation component is slidingly arranged in the guiding recesses, the additional deformation component forming a front component of the culvert and fitted with a soft layer made from a soft and resilient deformable material on at least the front part of the additional deformation component.
