Variable emergency isolation strip

Abstract

The invention discloses a variable emergency isolation strip and relates to the field of road engineering. The variable emergency isolation strip comprises a U-shaped base channel (1), a moving cover plate (2), at least two side retaining plates (3) and at least two transverse retaining plates (4). The variable emergency isolation strip is characterized in that moving cover plates (2) are arranged on the upper portion of the U-shaped base channel (1), the moving cover plates (2) and the U-shaped base channel (1) enclose a duct (5), and the side retaining plates (3), the transverse retaining plates (4) and the moving cover plates (2) enclose cells (6). Mainly, when road traffic accidents cause traffic jam, the variable emergency isolation strip can be quickly opened by maintainers to release traffic jam pressure by lifting up the side retaining plates (3), the transverse retaining plates (4) and the moving cover plates (2) with simple lifting equipment. The variable emergency isolation strip is good in collision avoidance, allows lane changing to be simple and fast, and is low in manufacturing cost; the functions such as solar power, electronic monitoring, drainage and disaster reduction can be expanded and integrated conveniently.

Description

technical field [0001] The invention belongs to the field of traffic and road engineering, in particular to a variable emergency isolation belt for roads. Background technique [0002] The isolation zone in the middle of the highway, especially the isolation zone in the middle of the expressway, as a necessary facility for high-grade highways, plays a very important role in driving safety, driving comfort, road landscaping, anti-glare facilities and communication pipeline configuration. important role. People often compare the isolation zone in the middle of the expressway to the "lifeline" set up to maintain the safety of two-way vehicles. However, with the high-speed take-off of my country's economy, the number of vehicles on the road is increasing day by day, and the speed of driving is increasing day by day, but the technical level of this central isolation zone as a life protection line has not been able to increase day by day and keep pace with the times. The outstand...

AI Technical Summary

Problems solved by technology

[0003] 1. The anti-collision performance of most isolation belts in the middle of the road is low, and it is difficult to block the collision of large and heavy vehicles. Even some isolation belts are improperly constructed and easily cause secondary injuries. For example: on March 27, 2009, on the Changzhang section of the Shanghai-Kunming Expressway, a bus crashed into the median strip and then rushed into the opposite lane, collided with a truck, killing 22 people, Major accident in which 12 people were injured in tragic condition

[0004] When this type of accident occurs, the vehicle causing the accident crashes into the central barrier and rushes into the opposite lane, and collides with the opposite vehicle head-on. Taking evasive measures will easily lead to disastrous consequences, mass death and mass injury, great loss of people's lives and property, great negative impact on society, and extremely profound lessons;

[0005] 2. A small part of the central median of the road is strong enough. Although it can basically prevent vehicles from rushing into the other lane when an accident occurs, it is not convenient to organize lane changes in a planned way because of its long continuous mileage and heavy weight. The pressure on one-way traffic jams has made the majority of drivers and passengers desperate during the long and boring wait

However, this kind of concrete rigid guardrail is bulky, cumbersome, low in standardization, heavy on-site construction work, slow in speed, high in overall cost, and oppressive in noise when driving.
