Wall type anti-collision movable rail

Abstract

The invention discloses a wall type anti-collision movable rail. The wall type anti-collision movable rail comprises end rails, male movable rails, female movable rails, rail male joints, rail female joints, embedded components and a ground foundation. Certain anti-collision grades can be met, and vehicle driving safety can be guaranteed; the requirements of road construction and maintenance can be met, the movable rail can be conveniently moved when a single-way lane is closed, and shunting of vehicles can be achieved; the movable rail can be rapidly opened when traffic accidents happen, the vehicles are rapidly evacuated, and rescue is rapidly carried out; the situation that drivers personally open the movable rail for vehicle turning can be avoided, a certain protection function is achieved, and the drivers cannot easily carry or detach the movable rail; theft acts of highway facilities are avoided, the movable rail is not provided with any small parts capable of being detached at will, and therefore the situation that after the small parts are stolen, the safety of the whole facilities is reduced is avoided; a tool for opening the movable rail has the functions of being light and easy to carry around, the tool can reach a site in a barrier-free mode when the traffic accidents happen, and the rescue time is shortened to the maximum extent.

Description

technical field [0001] The invention relates to a highway traffic safety facility, in particular to a wall-type anti-collision movable guardrail. Background technique [0002] The central movable guardrails of expressways in my country mainly include plug-in movable guardrails, telescopic movable guardrails, filling guardrails, prestressed guardrails, etc. The main disadvantages of the above movable guardrails are as follows: [0003] 1. Plug-in movable guardrail: the locking device is easy to be opened by the vehicle driver to turn around, which will cause traffic accidents. There is a greater safety risk, the material is easy to rust, the daily maintenance cost is high, and the anti-collision ability cannot reach the Am anti-collision level . [0004] 2. Telescopic movable guardrail: The locking device is easy to be opened by the vehicle driver to turn around, causing traffic accidents and posing a greater safety risk. The structure is relatively complicated, and the ope...

AI Technical Summary

Problems solved by technology

[0003] 1. Plug-in movable guardrail: The locking device is easy to be opened by the vehicle driver to turn around, which will cause traffic accidents. There is a large safety risk, the material is easy to rust, the daily maintenance cost is high, and the anti-collision ability cannot reach the Am anti-collision level

[0004] 2. Retractable movable guardrail: the locking device is easy to be opened by the vehicle driver to turn around, which will cause traffic accidents and pose a greater safety risk

The structure is relatively complicated, and the opening of the central belt is small after being folded, which is not convenient for vehicles to pass through. After damage, the maintenance cost is high, and the anti-collision ability cannot reach the Am anti-collision level

[0005] 3. Filled guardrail: it is easy to be turned around by the driver of the vehicle, which will cause traffic accidents. There is a large safety risk, poor structural durability, high maintenance cost, and the anti-collision ability cannot reach the Am anti-collision level

[0006] 4. Prestressed movable guardrail: the production process is complex, the cost is high, the daily maintenance cost is large, and the repair after damage is difficult and costly

[0007] At present, the central movable guardrail of the expressway generally does not meet the anti-collision requirements, leaving a great potential safety hazard. When a vehicle rushes over the movable guardrail, it is easy to rush to the opposite lane, causing great accident losses.
