道路防撞栏杆顾名思义，是道路两侧的波浪形防护栏杆，主要用于防止事故、区分车道和美化环境。当今社会发展越来越快，交通也越来越发达。许多城市非常重视道路建设。当然，道路波形防撞护栏也成为了它的一部分。
As the name suggests, anti-collision railings are wave-shaped protective railings on both sides of the road, mainly used to prevent accidents, distinguish lanes and beautify the environment. Today's society is developing faster and faster, and the traffic is more and more developed. Many cities attach great importance to road construction. Of course, the road waveform anti-collision guardrail has become a part of it.
由于缺乏精确的测量和详细的设计，一些波浪形防撞护栏美学效果不佳，功能不够完善，也影响了城市环境。有些人强调装饰，而忽略了波浪形防撞护栏的主要安全功能。例如，虽然不锈钢波浪形防撞护栏很漂亮，但它带来的光污染会引起眩目，影响安全。部分波浪形防撞护栏设计不规范，波浪形防撞护栏高度高影响城市景观，且波浪形重庆防撞护栏中间没有竖向限位杆或竖向限位杆间距过大，行人容易越过波浪形防撞护栏，存在安全隐患。有些波形梁护栏强度差，可人工拆除，容易损坏且无用。一些波形梁护栏有许多焊接点，底层没有经过防腐表面处理——。
Due to the lack of accurate measurement and detailed design, the aesthetic effect of some wave shaped crash barriers is not good, and the function is not perfect, which also affects the urban environment. Some people emphasize decoration, but ignore the main safety function of corrugated guardrail. For example, although the stainless steel wave shaped anti-collision guardrail is very beautiful, the light pollution it brings will cause glare and affect safety. The design of some wave shaped anti-collision guardrails is not standardized. The high height of the wave shaped anti-collision guardrail affects the urban landscape. There is no vertical limit bar in the middle of the wave shaped anti-collision guardrail in Chongqing, or the spacing between the vertical limit bars is too large, which makes it easy for pedestrians to cross the wave shaped anti-collision guardrail, and there is a potential safety hazard. Some corrugated beam guardrails have poor strength, can be removed manually, easy to damage and useless. Some corrugated beam guardrails have many welding points, and the bottom layer is not treated with anti-corrosion surface treatment.
