广州**工程波形防护栏现货|清远乡村公路路侧防撞栏杆|大量库存|公路波形梁钢护栏价格 厂家直销生产 价美物廉 长期备有现货 百闻不如一见,欢迎现场考察指导 波形梁护栏板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。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*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。路侧波形梁护栏的横断布设,不应使护栏面侵入公路建筑限界以内,并不得使护栏立柱外侧的侧向土压力明显减小。 波形护栏板的分类: 波形梁护栏一般按设置地点和防撞等级来分类。按设置地点可以分为路侧护栏和*分隔带护栏。按防撞等级可分为A级和S级。S级护栏属于加强型,适用于路侧特别危险的路段使用,A级用于**公路。 I don't think that will be necessary.
