波形护栏板

高速公路护栏板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 wave beam expanding column of the highway fence board is the main form of the semi rigid barrier, and it is a continuous structure with corrugated steel fence board and supported by the main column. It uses subgrade, column, beam deformation to absorb the collision energy, and forcing runaway vehicle to change direction, returned to the normal direction of travel, to prevent vehicle ran off the road, to protect the vehicle and passengers and reduce the 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。

Soft steel guardrail phase and has strong absorption collision energy of ability, with good sight induced function, in harmony with the road alignment, beautiful appearance, used in the small radius curve, damage easy replacement. Combination waveform beam fence can be used in a narrow central separation belt. For vehicles, the more way out (bridge), there may be a serious consequence of the section, can choose to strengthen the waveform beam fence.

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，该护栏由两片波形梁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。车辆对其碰撞时，由于波形钢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

W-beam guardrail guardrail utility model relates to a road central separating belt opening with combined waveform movable plate type steel guardrail, constitute the guardrail by two pieces of waveform steel guardrail plate and between the two clamped two columns, two column fixing clip is arranged between the two pieces of corrugated steel guardrail plate. When a road is in normal operation, the fence the column plug can be conveniently inserted into the opening of the pre-set the plug hole in, played the role of isolation and protection, and the road outside the fence with echoes, neat and tidy, beautiful package. Vehicle of the collision, due to the corrugated steel guardrail plate has good crashworthiness and energy absorption effect, which is not easy be crashed and the vehicle and a driver by personnel have very good protection effect. When the road maintenance or other reasons for the need and through, it can be convenient to open the opening of the column of the column to pull out the move to open up channels for the vehicle to pass
