TOPPLING PREVENTING STRUCTURE OF A PART OF A MOUNTAIN BRIDGE

摘要

The present invention relates to a bridge structure fall prevention structure of a mountain valley, the lower arc-shaped beam is convexly installed in the center between the two adjacent bridges in the direction crossing the cloth or valley of the mountain region; An upper arc-shaped beam formed convexly downwardly so that a center portion is joined to the lower arc-shaped beam in contact with the two piers; Lower coupling means for coupling both ends of the lower circular arc to the two piers; And upper coupling means for coupling both ends of the upper circular arc to the two piers, respectively. The present invention allows the structures of the road bridges of the valleys and rivers of the mountainous region to form a more solid coupling relationship between each other, preventing damage and collapse of the bridges in the event of landslides or floods, and more stable and safe bridges. It helps to secure the condition and improves the beauty of the bridge.
