Expressway medial strip portal protective guardrail and construction method thereof
The invention discloses an expressway medial strip portal protective guardrail. The guardrail comprises a fixing mechanism and a first sliding frame connected to the fixing mechanism in a sliding mode, a wave-shaped beam is fixedly connected to the first sliding frame, a second sliding frame is connected to the first sliding frame in a sliding mode, the second sliding frame is connected with the fixing mechanism through a connecting rod, a transmission mechanism is arranged on the first sliding frame,the upper portion of the first sliding frame is rotationally connected with a plurality of buffering mechanisms, the lower ends of the buffering mechanisms are rotationally connected to the connecting frame, the transmission mechanism is arranged on the first sliding frame, supporting columns are fixedly connected to the two sides of the fixing mechanism through bolts, and an embedded part is arranged on the lower side of each supporting column. After the vehicle is impacted, the included angle between the buffering mechanisms and the road surface can be changed through mutual cooperation of all the components, new downward thrust is provided for the vehicle through rotation of rolling wheels to increase friction force between the vehicle and the road surface, and then the controllability of the vehicle after being impacted is improved.
本发明公开了一种高速公路中央分隔带门架防护护栏，包括固定机构及滑动连接在所述固定机构上的第一滑架，所述第一滑架上固定连接有波形梁，所述第一滑架上滑动连接有第二滑架，所述第二滑架与所述固定机构之间通过连杆连接，所述第一滑架上设置有传动机构的上部转动连接有若干个缓冲机构，若干个所述缓冲机构的下端均转动连接在连接架上，所述第一滑架上设置有传动机构，所述固定机构的两侧均通过螺栓固定连接有支撑柱，所述支撑柱的下侧设置有预埋件；可以受到撞击之后通过各个部件之间的相互配合，改变缓冲机构与路面之间的夹角，利用滚轮的转动给车辆一个向下新的推力来增加车辆与路面之间的摩擦力，进而提高车辆受到撞击后的控制性。
