The invention discloses a foldable guardrail, wherein the guardrail bases (1) are fixed to the two sides of a bridge floor, the multiple folding devices (10) are installed on the upper surfaces of theguardrail bases (1), the stand columns (5) are installed between two side plates of the folding devices (10) and connected with the side plates of the folding devices (10) through rotating shafts, and the cross beams (6) are fixedly connected with the stand columns (5). The stand column (5) can be placed in the vertical direction and can be placed down during flood. The foldable guardrail has ananti-collision function, and the anti-collision grade can reach the SA grade; and the method plays an important role in transformation of the existing bridge guardrail which is easily submerged by flood.
本发明公开了一种可折叠式护栏，包括固定于桥面两侧的护栏底座(1)、安装于所述护栏底座(1)上表面的多个折叠装置(10)、安装于所述折叠装置(10)两侧板之间且与所述折叠装置(10)侧板通过转轴连接的立柱(5)、与所述立柱(5)固定连接的横梁(6)，所述立柱(5)可沿竖直方向放置，洪水时可放倒设置。该可折叠式护栏具有防撞功能，防撞等级可达到SA级；对于易遭受洪水淹没的既有桥梁护栏改造有重要作用。
