高速護欄板為何都用防阻塊連接

我們看見的農村公路上的波形護欄全是用防阻塊用來連接立柱的，通常道路和鄉(xiāng)間道路有的用防阻塊，有的用托架，那麼高速護欄板板連接立柱為何必須用防阻塊波形護欄與立柱加了防阻塊有什么好處呢

防阻塊自身只是1個吸能機構，因而，能夠使護欄在遭受撞擊后逐步變形，有益于動能消化，降低乘員事故；防阻塊放置在立柱與波形梁中間，使波形梁從立柱上懸置下來。無法控制的車輛一旦與護欄發(fā)生撞擊，不會因為波形梁緊靠立柱，而使前輪在立柱處絆阻；防阻塊參加護欄總體作用后，能夠使撞擊力分派到大量跨構造上，進而使護欄支承更為勻稱，使護欄的撞擊軌跡比較圓滑，有益于車輛的導向和提升護欄的總體強度。有路側石路段設定防阻塊護欄時，可讓波形梁與緣石面的間距減小，緩解甚至消除由于無法控制車輛碰到緣石后跳起產生對護欄的不良影響危害。

顏色：鍍鋅銀白色，噴塑綠色，白色，藍色等。

按波形可分為雙波波形護欄和三波波形護欄。

按表面處理分為熱鍍鋅波形護欄和鍍鋅噴塑兩種。

按設置地點可以分為路側護欄和中央分隔帶護欄。

公路波形護欄板按防撞等級可分為A級和S級。S級護欄屬于加強型，適用于路側特別危險的路段使用，A級用于專用公路。常用路側波形梁護欄按防撞等級可分為B、A、SB、SA、SS五級
