Highway emergency tailgating dredging bridge

Abstract

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.

Description

technical field [0001] The invention belongs to the field of road emergency rescue equipment, in particular to an expressway emergency diversion bridge. Background technique [0002] With the development of my country's social economy and the acceleration of urbanization, the transportation industry has developed rapidly, and the number of private cars has increased sharply. The resulting traffic demand and the continuous increase in traffic volume have made traffic congestion increasingly prominent, especially during peak holiday periods when the public travels intensively. [0003] After a traffic accident or natural disaster occurs on the expressway, the traffic capacity of the road section will decrease significantly, which will easily cause traffic congestion or congestion, which will seriously affect the operation safety and efficiency of the expressway itself, and even cause secondary traffic accidents. Due to the one-way driving and closed management of the expressw...

AI Technical Summary

Problems solved by technology

[0003] After a traffic accident or natural disaster occurs on the expressway, the traffic capacity of the road section will decrease significantly, which will easily cause traffic congestion or congestion, which will seriously affect the safety and efficiency of the expressway itself, and even cause secondary traffic accidents.

Due to the one-way driving and closed management of the expressway, when a major accident or natural disaster occurs at the accident point of the expressway, when the one-way interruption causes the vehicle behind to be stranded and unable to move forward, it is impossible to turn back, so some drivers choose the emergency lane to pass. It is easy to cause secondary traffic accidents and injuries, and hinder the development of expressway accident rescue operations
