ANTI-COLLISION BARRIER Russian patent published in 2015 - IPC E01F13/12 

FIELD: construction.

SUBSTANCE: anti-collision barrier is intended for protection against unauthorised passage of transport vehicles. A barrier includes a swing-beam installed in cavities of fixing supports, which are fixed on foundation projections along edges of the road driveway. The swing-beam is connected to an electrohydraulic actuator; steel racks are mounted in blind holes on the lower side of the swing-beam and represent elastic connections of spring-loaded shells connected with screw cylindrical springs. The racks are fixed in holes by means of couplings tightly put on the swing-beam and made from brittle material destructed at the specified impact force. Destruction of couplings is accompanied by stepwise entry of free ends of the racks into the cavities made in the road bed immediately under the swing-beam.

EFFECT: improvement of a protection degree.
