FIELD: roads.SUBSTANCE: invention relates to end (starting and final) sections of barrier-type road guard, primarily, to guard structures using as a beam a bent profile. End section, made of beams fixed on poles with possibility of linking with working section before or after it, contains the first section (8), configured to link with the working section, and the second section (10) linked to the first section, at that a beam (9) of the first section is fitted with a longitudinal slope towards the road surface, and a beam (18) of the second section is directed, in fact, parallel to the road surface. In the joint of the first section to the second section angular element (16) can be installed for connection of beams of these sections at an angle, identical to angular element installed in the joint of the first section with working section. Lower edge of the beam (18) of the second section can be located both on the road surface, and under or above that surface. At the free end of the second section head (20) can be installed, adjacent to the end of the beam (18) and made with longitudinal slope from the end of the beam to the road surface secured separately from the beam.EFFECT: preliminary car deceleration is provided at running over the end of the guard in axial direction to the moment of its interaction with tilted beam, volume of excavation works is reduced and repairability of guard is improved as well.5 cl, 9 dwg |
