公路护栏板对公路上的安全的保障是很重要的,而公路护栏板的防阻块对于公路护栏板来说,更是缺一不可的重要部件,公路护栏板主要的作用就是将护栏板立柱与波形护栏板连接起来,起到很好的缓解冲击力的效果。
防阻块与护栏板都是标配的,在使用过程中不要使用其他种类的防阻块,因为防阻块过大或过小都大大减低护栏板的防护效果,不能有效减缓冲击力对立柱的冲击。防阻块与立柱都是经过热镀锌防腐处理的,这样大大提高了防阻块的使用寿命。国家对标准防阻块有明确的规定尺寸为196*178*200*4。防阻块的横截面为正六边形中空,但受到冲击力的时候,可以通过自身的变形减缓压力。 防阻块另外的一种防腐处理方法是进行浸塑、喷塑处理,防腐效果也非常好,在美观度方面更为突出。喷塑处理可为多种颜色,目前用量较大的为绿色。
