Highway emergency tailgating dredging bridge
The invention provides a highway emergency tailgating dredging bridge which comprises an upper bridge section, a main bridge section and a lower bridge section. The upper bridge section is arranged on the innermost side lane of a highway section to be dredged and forms a certain included angle with the highway surface. The lower bridge section is arranged on the innermost side lane of an opposite highway section and forms a certain included angle with the highway surface. The main bridge section is arranged at the upper portion of an isolation belt in a highway middle isolation strip. The width of the upper bridge section, the width of the main bridge section and the width of the lower bridge section are larger than the width of a vehicle. When vehicles in one direct are delayed and a traffic jam is caused due to the fact that a traffic accident or a natural disaster happens on a highway, the highway emergency tailgating dredging bridge is conveyed to the lane in the opposite direction through the vehicles, the small vehicles can be dredged and evacuated from the region through the bridge by means of the opposite lane, pass through the accident region and then return to the original highway for normal running through the dredging bridge, the purpose that vehicles can pass by means of the opposite lane when delayed on the highway and secondary accidents on the highway can be reduced are achieved, the vehicles are prevented from occupying an emergency vehicle lane, and implementation of emergency rescue operation is ensured.
