REMOVABLE PREFABRICATED BARRIER Russian patent published in 2023 - IPC E01F13/12 E01F9/654 

FIELD: organizing the passage of land transport.

SUBSTANCE: removable pre-fabricated barrier is made in form of a polyhedron. The polyhedron is made collapsible from interconnected faces, which are made in the form of polygons with the possibility of unfolding the polyhedron from the assembled position to the transport position by relative change in the position of the faces. The polyhedron is provided with protrusions located outside the outer boundaries of its faces. The protrusion is formed by making a face in the form of a polygon, the number of vertices of which exceeds the number of faces conjugated with the specified face.

EFFECT: ensuring compactness during transportation of the road barrier, reducing the time for installing the barrier in the required position while ensuring the reliability of the erected barrier.
