The invention discloses a novel buffering waveform guardrail, and relates to the technical field of anti-collision guardrails. The novel buffering corrugated guardrail comprises a stand column, a corrugated guardrail body and a buffering layer, the buffering layer is fixed to the right side of the upper end of the stand column through two sets of fastening bolts, the corrugated guardrail body is arranged on the right side of the buffering layer, and the buffering layer comprises an inner partition plate, buffering rubber, an outer partition plate and a connecting column. According to the novelbuffering waveform guardrail, the factor that the collision force should be smaller than the resilience force of the springs is fully considered, the springs with the stiffness coefficient being 15 KN/mm are selected, the compression amount of the springs is limited to be 10 mm, and a sliding friction force lower than the sliding friction force between a small automobile tire and the bottom facecan be provided; therefore, the danger that the automobile rebounds to the lane when the springs return to deform after the guardrail is collided is reduced.
本发明公开了一种新型缓冲波形护栏，涉及防撞护栏技术领域。该新型缓冲波形护栏，包括立柱、波形护栏和缓冲层，所述立柱上端的右侧通过两组紧固螺栓固定有缓冲层，所述缓冲层右侧设置有波形护栏，所述缓冲层包括内隔板、缓冲橡胶、外隔板和连接柱。该新型缓冲波形护栏充分考虑到碰撞力应小于弹簧回弹力的因素，选用劲度系数为15KN/mm的弹簧，并限制弹簧的压缩量为10mm，可以提供低于小型汽车轮胎与底面的滑动摩擦力，从而减少汽车在于护栏发生碰撞后弹簧回复形变时将汽车弹回车道的危险。
