Description

一种立交桥 技术领域
本实用新型涉及交通技术领域，具体涉及一种立交桥。
背景技术
当前城市发展快速，堵车问题降低了道路的通行效率。目前的交叉路口采用交通信号灯设置，车辆经过路口处需要交通排队通过。当车辆不是特别多时，交通信号灯设置的路口有一定的通行效率。当车辆特别多时，交通信号灯设置的路口很容易造成严重的堵车，甚至需要人为的指挥。交叉路口现有设计的立交桥占地面积大、结构复杂、实施难度大不易推广。交叉路口堵车这一问题越来越严重。
发明内容
本实用新型实施例的目的在于提供一种立交桥，用以解决现有交叉路口车辆拥堵的问题。
为实现上述目的，具体地，该立交桥包括相交错的主车道和副车道，主车道的中部设有一个跨越副车道的直行高架桥，主车道在直行高架桥的右侧设有至少一条右转弯车道与至少一条左转弯车道，左转弯车道位于右转弯车道和直行高架桥之间；直行高架桥的两侧分别设有一个直角形的交通信号灯，交通信号灯包括相互垂直的第一信号灯臂和第二信号灯臂，第一信号灯臂与第二信号灯臂均水平设置，第一信号灯臂固定在直行高架桥的侧边上，第一信号灯臂为副车道的直行车道和左转弯车道提供交通指示灯光，第二信号灯臂为主车道的左转弯车道提供交通指示灯光。
所述的直行高架桥的中部沿其长度方向设有隔离带。隔离带能够减少来向汽车带来的气流扰动和压迫感，进一步提高通行效率，减少交通事故。
所述的直行高架桥的两端分别设有直行标识牌。直行标识牌能够提前提示驾驶员车道设置，具有提前提示作用，防止驾驶者紧急变线到左转弯，影响其他车辆的行驶。
所述的直行高架桥的中部沿其长度方向设有隔离带，直行标识牌设置在隔离带的两端上方。
所述的直行高架桥的下坡处设有照明灯和反光镜，反光镜的镜面朝向直行高架桥上的车道，且反光镜为凸面镜。由于直行高架桥上驾驶员视野受到路面影响，在下坡时无法及时观察到前方车辆情况，尤其是晚间，本实施例通过设置照明灯在晚间能够提供较好的照明，并且通过反光镜驾驶员可以提前观察前面车辆情况，防止车辆下坡时发生追尾。
所述的直行高架桥下方的副车道两侧设有人行横道，在人行横道与副车道之间设有隔离栏。隔离栏在不影响车辆转弯情况下，能够减少行人对车辆的干扰，增加车辆通行的效率。
所述的隔离栏的长度小于直行高架桥的宽度，能够有效减少隔离栏对主车道的左转弯车道车辆的影响。
所述的主车道为双向八车道，直行高架桥与主车道中间的四个车道相连接，主车道在直行高架桥右侧的两个车道分别为右转弯车道和左转弯车道。
本实用新型实施例具有如下优点：
本实用新型实施例的立交桥结构简单、施工方便、易推广，主车道上主要是直行车辆，直行车辆通过直行高架桥可以直接通过路口，能够有效改善交叉路口的堵车问题，提高交叉路口通行效率。
直角形设计的交通信号灯方便主车道和副车道驾驶者都能看到，而且也省去立柱，结构简单，成本低，安装、维修方便。

具体实施方式
以下实施例用于说明本发明，但不用来限制本发明的范围。
实施例1
参见图1，该立交桥包括相交错的主车道1和副车道2，主车道1的中部设有一个跨越副车道2的直行高架桥3，主车道1在直行高架桥3的右侧设有一条右转弯车道与一条左转弯车道，左转弯车道位于右转弯车道和直行高架桥3之间，主车道1上直行车辆直接通过直行高架桥3通过路口，左转弯车辆通过直行高架桥3右侧的左转弯车道驶入副车道2，右转弯车辆通过右转弯车道驶入副车道2。结构简单、施工方便、易推广，能够有效改善交叉路口的堵车问题，提高交叉路口通行效率。
直行高架桥3的中部沿其长度方向设有隔离带4，隔离带4能够减少来向汽车带来的气流扰动和压迫感，进一步提高通行效率，减少交通事故。直行高架桥3的两端分别设有直行标识牌5，直行标识牌5设置在隔离带4的两端上方，直行标识牌5能够提前提示驾驶员车道设置，具有提前提示作用，防止驾驶者紧急变线到左转弯，影响其他车辆的行驶。
直行高架桥3的下坡处设有照明灯6和反光镜7，反光镜7的镜面朝向直行高架桥3上的车道，且反光镜7为凸面镜。由于直行高架桥3上驾驶员视野受到路面影响，在下坡时无法及时观察到前方车辆情况，尤其是晚间，本实施例通过设置照明灯6在晚间能够提供较好的照明，并且通过反光镜7驾驶员可以提前观察前面车辆情况，防止车辆下坡时发 生追尾。本实施例将照明灯6设置在隔离带4上方，进一步提高直行高架桥3上的亮度，进一步避免追尾。
直行高架桥3下方的副车道2两侧设有人行横道，在人行横道与副车道2之间设有隔离栏9。隔离栏9在不影响车辆转弯情况下，能够减少行人对车辆的干扰，增加车辆通行的效率。隔离栏9的长度小于直行高架桥3的宽度，能够有效减少隔离栏9对主车道1的左转弯车道车辆的影响。
本实施例中的主车道1和副车道2均为双向八车道，包括A、B、C、D、E、F、G、H八条车道，直行高架桥3与主车道1中间的C、D、E、F四个车道相连接，其中C、D为正向车道，则E、F为反向车道。主车道1在直行高架桥3右侧的A车道为右转弯车道，B车道为左转弯车道。
参见图1～2，直行高架桥3的两侧分别设有一个直角形的交通信号灯8，交通信号灯8包括相互垂直的第一信号灯臂10和第二信号灯臂11，第一信号灯臂10与第二信号灯臂11均水平设置，第一信号灯臂10固定在直行高架桥3的侧边上，第一信号灯臂10为副车道2的直行车道和左转弯车道提供交通指示灯光，第二信号灯臂11为主车道1的左转弯车道提供交通指示灯光。
实施例2
本实施例中的主车道1与副车道2均为双向六车道。
实施例3
本实施例中的主车道1为双向八车道，副车道2为双向六车道。
虽然，上文中已经用一般性说明及具体实施例对本实用新型作了详尽的描述，但在本实用新型基础上，可以对之作一些修改或改进，这对本领域技术人员而言是显而易见的。因此，在不偏离本实用新型精神的基础上所做的这些修改或改进，均属于本实用新型要求保护的范围。
