The invention discloses a road and bridge protective fence, and relates to the technical field of protective fences. The auxiliary guardrails comprise a first guardrail and a second guardrail; the first protective fence is arranged on one side of the fixed protective fence, and a buffer assembly is arranged between the first protective fence and the fixed protective fence; the second protective fence is arranged above the first protective fence, the bottom end of the second protective fence is hinged to the top end of the first protective fence, the top end of the second protective fence is connected with the top end of the fixed protective fence through a connecting plate, and the two ends of the connecting plate are hinged to the second protective fence and the fixed protective fence respectively; wherein the second protective fence is provided with a cavity, an air bag and a high-pressure tank are arranged in the cavity, and the air bag is connected with the high-pressure tank through a pipeline. When a vehicle collides with the first protective fence, the second protective fence and the first protective fence rotate relatively, and then the connecting plate is driven to rotate towards the second protective fence, so that the top of the vehicle is blocked by the connecting plate, and the vehicle is prevented from rolling over.
本发明公开了一种道路桥梁防护栏，涉及防护栏技术领域，包括：固定护栏；辅助护栏，辅助护栏包括第一防护栏和第二防护栏；第一防护栏设置在固定护栏的一侧，第一防护栏和固定护栏之间设置有缓冲组件；第二防护栏设置在第一防护栏的上方，第二防护栏的底端与第一防护栏的顶端铰接，第二防护栏的顶端与固定护栏的顶端通过连接板连接，连接板的两端分别与第二防护栏和固定护栏铰接；其中，第二防护栏具有腔体，腔体内设置有气囊和高压罐，气囊与高压罐通过管路连接。本发明在车辆与第一防护栏发生碰撞时，第二防护栏与第一防护栏之间会发生相对转动，进而带动连接板向第二防护栏方向旋转，以实现连接板对车辆顶部的阻挡，防止车辆发生侧翻。
