The invention discloses a semi-rigid guardrail and an installation method thereof and relates to the technical field of guardrails. The semi-rigid guardrail comprises concrete prefabricated parts, wherein every two adjacent concrete prefabricated parts are connected through a rectangular pipe, and two parallel installation feet are arranged at the bottom of each concrete prefabricated part. When a vehicle impacts the guardrail with a quite large force, the concrete prefabricated part transmits the transverse impact force to the inverted-U-shaped inner side mounting foot at a bottom end, and the part is weak and fractures after reaching the limit, so the concrete prefabricated part transversely shifts, the buffering effect is achieved, and the transverse impact force of the vehicle is eliminated. The method is advantaged in that characteristics that a rigid guardrail is high in protection performance and low in later maintenance cost are reserved, the overall weight is reduced, snow cannot be blocked, and the application range is widened; and the buffering effect of a semi-rigid guardrail is achieved, and the consequence of collision accidents is relieved.
本发明公开了一种半刚性护栏及其安装方法，涉及护栏技术领域，包括混凝土预制件，每相邻的两个混凝土预制件通过矩管相连接，所述混凝土预制件底部设置有两条平行设置的安装脚。如果车辆以一个相当大的力撞击护栏时，混凝土预制件会把这个横向撞击力传入底端的倒“U”型内侧安装脚，这个地方由于比较薄弱，达到极限后会发生断裂，从而使得混凝土预制件发生横向偏移，达到缓冲作用，消除车辆的横向撞击力。本发明保留了刚性护栏防护性能强，后期维护成本较低的特点，缩小了整体重量，不会阻雪，增加了其适用范围；又具备半刚性护栏的缓冲作用，减轻了碰撞事故的后果。
