MEDIAN STRIP FOR EXPRESSWAY & IMPROVED ENGINEERING METHOD OF GUARD RAIL FOR BRIDGE AND THAT GUARD RAIL & THE MEDIAN STRIP

摘要

PURPOSE: An improvement method of a handrail barrier for a median strip and a bridge, a median strip thereof, and a handrail barrier thereof are provided to minimize a secondary accident caused by broken pieces by minimizing the scattering the broken pieces. CONSTITUTION: A handrail barrier(1) for a median strip and a bridge comprises an existing median strip, a center support anchor(20), overturn prevention anchors(21,22), reinforcing bars(30), concrete adhesive(40), a non-dismantling form(10), and concrete(50). The center support and overturn prevention anchors are vertically installed in the left and right ends and outer side of the existing median strip. The reinforcing bars are coupled to the center support and overturn prevention anchors and are installed on the outer surface of the existing median strip. The concrete adhesive is spread on the existing median strip. The non-dismantling form is separated from the outer wall of the existing median strip. The concrete is placed inside the non-dismantling form and cured.
