        贵州波形护栏板立柱埋入高度标准,波形护栏的立柱埋入高度根据路基的不同埋入标准也大不相同下面为大家讲解两种路基埋入的深度标准:

        一般埋入土基的波形护栏立柱:

        1、DANGHULANLIZHUMAIZHITUZHONGQIEWULUYUANSHISHI,LIZHUMAISHENBUYINGXIAOYU110cm ;

        汽车重量主要集中在底盘,车辆翻过护栏需要足够的角动量,因此,一般情况下只要护栏高度能够拦住车轮,就可以起到防护作用.波形梁护栏的横梁中心高度,从路面算起至连接螺栓孔中心的距离为60cm. 当设有路缘石时,横梁的中心高度从路缘石顶面算起至连接螺栓孔中心的距离为60cm.当波形梁护栏有防阻块时,其中心高度不变.所以国标中护栏板中心的最低高度不能低于60cm,是经过理论计算,并考虑安全度的.
