Guardrail with buffer device and mounting method
The invention provides a guardrail with a buffer device and a mounting method, belongs to the field of road and bridge engineering, particularly relates to a guardrail capable of buffering automobile impact force, and mainly solves problems that the exposed height of curbs of an existing bridge or road retaining wall embankment does not meet the new specification requirement, and defects exist when the guardrail is additionally installed. The guardrail is mainly composed of a base, a vertical arm and a cross beam and installed at the position, close to a roadway, of the sidewalk side, the base is provided with a buffering device, and the vertical arm is elastically connected with the base. When the cross beam is impacted by a vehicle, the vertical arm drives the top plate to rotate around the hinged shaft, and the top plate compresses the spring to buffer the impact force of the vehicle. The guardrail does not occupy the effective width of the roadway during installation, the impact force of a vehicle can be buffered through elastic connection, and damage to the vehicle and the guardrail is relieved.
本发明提供一种带缓冲装置的护栏及安装方法，属于道路、桥梁工程领域，特别涉及一种能够缓冲汽车冲击力的护栏。主要解决现有桥梁或道路挡土墙路堤的路缘石外露高度不满足新规范要求，加装护栏存在缺陷的问题。主要由基座、立臂、横梁组成，安装在人行道边靠近车行道的位置，基座设置有缓冲装置，立臂与基座为弹性联接。横梁受到车辆撞击时，通过立臂带动顶板绕铰轴转动，顶板压缩弹簧，缓冲车辆的撞击力。护栏安装不占用车行道的有效宽度，弹性联接可以缓冲车辆的撞击力，减轻车辆和护栏的损坏。
