CULVERT WITH A DEFORMATION ZONE

摘要

The culvert with the deformation zone consists of prefabricated components arranged in the road ditch (1). The culvert includes at least one fixed basic component and at least one deformation component sliding in the basic component in the direction of the longitudinal ditch axis (1) and covered by a deformable decking or also by backfilling or other cover. The substance of the invention lies in the fact the basic component consists of a set of prefabricated concrete or reinforced concrete beds (2) formed in "V"-shape and placed one after another on the concrete base (3) in the road ditch (1) so that the shoulders (2a, 2b) of the beds (2) abut the ditch walls (1). Both shoulders (2a, 2b) of each bed (2) are fitted with opposite guiding recess (4) in the upper part for placement of deformation components formed by a set of at least two lateral rigid girders (5) installed with the possibility of the sliding movement in the direction of the longitudinal ditch axis (1). There are deformation gaps (6) between each lateral girder (5) and at least one front of the culvert contains at least one further deformation component in the recesses (4) with possibility of sliding movement that forms the front component (7) fitted with soft layer (14) from soft and resilient deformable material on at least its front part.
