| 防眩护栏板构造 Structure of anti glare guardrail board 道路上使用的防眩设施的构造可分为三种类型，是指连续封闭型的防眩设施，它基本上阻止了对向车道从水平面上所有角度射来的光线。如足够宽度的中央分隔带上的树墙等。 There are three types of anti glare facilities used on the road. They are continuous closed anti glare facilities, which basically prevent the light from the opposite lane from all angles on the horizontal plane. For example, a tree wall on a central divider of sufficient width. Ⅱ型：是由连续网状结构组成的防眩设施，它能阻挡水平面上o—^角度射来的光线，在^角以外可横向通视。金属(或塑料)防眩网为其代表形式。 Type II: it is an anti glare device composed of continuous mesh structure, which can block the light from O - ^ angle on the horizontal plane, and can be seen horizontally outside the ^. Metal (or plastic) anti glare net is its representative form. Ⅲ型：是以一定的间距连续设置板状结构而组成的防眩设施，它能阻挡水平面上o角度射来的光线，在吕角以外可横向通视。金属(或塑料)防眩板为其代表形式。防眩扇板、百叶窗式防眩栅、一定间距植树等从遮光原理上讲均是Ⅲ型防眩设施。 Type III: it is an anti glare device composed of continuous plate-shaped structure at a certain distance. It can block the light from O angle on the horizontal plane, and can be seen horizontally outside the angle of Lu. Metal (or plastic) anti glare plate is its representative form. Anti glare fan board, shutter type anti glare grid, planting trees at a certain distance are all type III anti glare facilities in terms of shading principle. 公路上广泛使用的防眩设施结构形式主要为防眩板，其次为植树、防眩网防眩板是一种经济美观，对风阻挡小，积雪少，对驾驶员心理影响较小的比较理想的防眩结构形式。因此，就防眩板的设置来说，主要有三种情况：(1)防眩板单独设置；(2)防眩板设置在波形粱护栏的横梁上；(3)防眩板设置在混凝土护栏上。 Anti glare plate is widely used in highway, followed by tree planting and anti glare net. Anti glare plate is an ideal anti glare structure with less wind barrier, less snow and less psychological impact on drivers. Therefore, there are three kinds of anti glare board: (1) the anti glare plate is set separately; (2) the anti glare board is set on the beam of wave beam guardrail; (3) the anti glare board is set on the concrete guardrail. |
