Abstract

一种双峰式混凝土护栏，该护栏一端有主波峰1，另一端有附波峰2，本发明结构简单，采用了对失控车辆的回弹进行主动导向的新概念，特别适合于高速公路的安装使用。

Description

双峰式混凝土护栏
本发明属于安全护栏，特别是用于高速公路上的混凝土护栏。
护栏是高速公路上不可缺少的安全设施，其主要作用就是为防止失控车辆越出公路或闯入对面车道，保护从员安全和避免二次事故。单峰式混凝土护栏(图1)是目前应用最广的公路安全护栏中的一种。主要用于公路中央分隔带及桥梁等。其最大的特点是占地面积小。目前单峰混凝土护栏，主要是通过迎撞面的坡度设计来减缓撞击程度。这种设计存在一个很大的问题；就是失控车辆很容易被弹入其它车道，这样在车流量大时极易造成二次事故。
本发明的目的是提出一种双峰式混凝土护栏，该护栏对失控车辆的回弹进行主动导向控制。
本发明的主要特点是在护栏的一端有一主波峰1，在另一端有一附波峰2。
本发明结构简单，采用了对失控车辆的回弹进行主动导向的概念，特别适合于高速公路上安全使用。
附图1为单峰式混凝土护栏断面示意图。
附图2为双峰式混凝土护栏断面示意图。
图中1为主波峰，2为附波峰，3为导向沟
下面结合附图详述本发明。
由附图2可以看出，双峰式混凝土护栏主要有两个混凝土波峰组成，设护栏引入了对失控车辆回弹的主动控制的概念。这种护栏的迎撞面一改传统的单峰设计，主波峰(1)用来控制失控车辆不越过护栏；附波峰(2)用来对失控车辆进行回弹导向。当失控车辆与护栏相撞时，车轮首先与附波峰2接触发生碰撞，使失控车辆在越过附波峰2时已经开始转向。这样在失控车辆与主波峰1发生碰撞时车身已基本与护栏平行，从而起到减缓冲击的作用，使失控车辆一侧车轮进入两峰间的导向沟。由于附波峰的存在，这种护栏还降低了失控车辆倾覆的可能性。同时，主波峰1和附波峰2都具有一定的减缓冲击的作用。
主波峰1与附波峰2之间的距离为18cm-45cm，α1为45°-90°，α2为60°-90°，其具体参数可根据需要调整。

Claims (2)

1、双峰式混凝土护栏，在其一端有主波峰(1)其特征为在另一端有一附波峰(2)。
2、按权利要求1所述的护栏其特征为主波峰(1)与附波峰(2)之间的距离为18CM-45CM，附波峰(2)迎撞面与地面的夹角α1为45°-90°，附波峰(2)导向面与导向槽底(3)的夹角α2为60°-90°。
