FIELD: construction. ^ SUBSTANCE: road barrier fence comprises at least one longitudinal metal bar fixed through compensators on several vertical metal stands embedded into soil base, and codirectional diagonal braces, which are fixed to bar by their front ends along with motion of motor transport, and with their back ends - to bases of stands near soil. At the same time braces are made of polymer composition on the basis of polyolefin. ^ EFFECT: increased retention strength of barrier, reduced value of dynamic bending and prevention of stands bending due to additional deformation of polymer diagonal brace in case of external forces effect and transformation of kinetic energy of shock from a colliding vehicle into a relative extension of brace, and therefore provides for more efficient, compared to analogs, suppression of colliding transport speed before barrier structure damage starts. ^ 1 cl, 6 dwg |
