Highway guardrail convenient to repair
The invention belongs to the technical field of road guardrails, and particularly relates to a road guardrail convenient to repair, which comprises upright posts and guardrail plates, the upright posts further comprise lower upright posts positioned underground and upper upright posts positioned above the ground, and foundation pits used for placing the lower upright posts and provided with inner walls made of reinforced concrete are arranged below the upright posts. The foundation pit is densely filled with a buffer block; a plurality of extrusion blocks which are staggered in the radial direction of the lower stand column are fixed on the lower stand column. The problems that in the prior art, a guardrail is difficult to repair, and the repair cost is high are solved; when collision energy is small, the buffer blocks in the foundation pit can fully absorb energy, collision deformation of the stand columns is reduced, the repairing difficulty of the stand columns is lowered, the maintenance cost is reduced, and the maintenance time is saved. When collision is severe, the stand columns abut against the edge of the foundation pit, and the automobile is prevented from rushing out of the road through the rigidity of the stand columns and extrusion of the extrusion blocks on the buffer blocks.
本发明属于公路护栏技术领域，尤其涉及一种便于修复的公路护栏，其包括立柱和护栏板，立柱还包括位于地面以下的下立柱和位于地面以上的上立柱，立柱下设置有一个用于放置下立柱的、内壁由钢筋混凝土制成的基坑，基坑内密实填充有缓冲块；下立柱上固定有若干沿下立柱径向交错排布的挤压块。本发明解决了现有技术中护栏修复困难且修复成本高的问题；当碰撞能量较小时，基坑内的缓冲块能充分吸收能量，减小立柱的碰撞变形，降低立柱的修复难度，减少了维修成本，节约了维修时间。当碰撞较为剧烈时，立柱抵在基坑边缘依靠自身刚度和挤压块对缓冲块的挤压共同防止汽车冲出道路。
