波形梁护栏是半刚性护栏的主要形式，它是一种以波纹状钢护栏板相互拼接并由主柱支撑的连续结构。它利用土基、立柱、横梁的变形来吸收碰撞能量，并迫使失控车辆改变方向，回复到正常的行驶方向，防止车辆冲出路外，以保护车辆和乘客，减少事故造成的损失。
The corrugated beam guardrail is the main form of the semi-rigid guardrail, which is a continuous structure which is connected with a corrugated steel guardrail plate and is supported by the main column. It uses the deformation of soil base, column, beam to absorb collision energy, and forcing the vehicle to change direction, and return to the normal direction of travel, to prevent the vehicle off the road, to protect the vehicle and passengers to reduce losses caused by the accident.
波形梁护栏钢柔相兼，具有较强的吸收碰撞能量的能力，具有较好的视线诱导功能，能与道路线形相协调，外形美观，可在小半径弯道上使用，损坏处容易更换。组合波形梁护栏可在窄中央分隔带上使用。对于车辆越出路(桥)外，有可能造成严重后果的区段，可选择加强波形梁护栏。
Steel guardrail phase and soft, with a strong ability to absorb impact energy, and has good sight inducing function, can coordinate with the road alignment appearance, can be used in a small radius, easy to replace damage. Combined wave beam guardrail can be used in narrow central separation belt. For vehicles out of the way (bridge), there may be serious consequences of the section, you can choose to strengthen the waveform beam guardrail.
波形护栏波形护栏实用新型涉及一种公路中央分隔带开口处用组合型波形板活动式钢护栏，该护栏由两片波形钢护栏板及两者之间固定夹放的两根立柱构成，两根立柱固定夹装在两片波形钢护栏板之间。在公路正常营运时，该护栏利用插拔立柱可方便地插入开口处预先设置的插拔孔内，起到隔离和防护作用，同时与公路外边上的护栏带相呼应，整齐划一，美观配套。
Guardrail guardrail utility model relates to a highway median openings with combination wave plate movable steel guardrail, the fence between two sheets of corrugated steel fence board and two clamp two columns placed a two column clips mounted between two sheets of corrugated steel fence board. Normal operation of the road, the plug hole of the fence post using the plug can be conveniently inserted into the opening set, played the role of isolation and protection, while on the road outside the fence with echoes, uniform, beautiful package.
车辆对其碰撞时，由于波形梁护栏板有良好的耐撞性能和吸收能量的作用，既不容易被撞毁，同时又可对车辆和司乘人员起到很好的保护作用。当路面维修或其它原因需要并通时，可方便地把开口处的各组护栏立柱拔出移走，开辟通道，便于车辆通行。
On the vehicle collision, the corrugated steel fence boards have good crashworthiness and energy absorption effect, it is not easy to be destroyed, and the vehicle and passengers have very good protection effect. When the road surface maintenance or other reasons need to be communicated, it is convenient to pull out each group of guardrail posts at the opening to open the passage, which is convenient for the vehicle to pass.
