Assembled reinforced protection and isolation guardrail

Abstract

The invention provides an assembled reinforced protection and isolation guardrail, and belongs to the field of highway traffic facilities. The installation and operation of the assembled reinforced protection and isolation guardrail is significantly simplified, the assembly speed is fast, the industrialization process is advantageously promoted, the construction cost is low, the industrialized disassembly is convenient and the installation is easy. The collision prevention and shock absorption coordination energy dissipation capability of the guardrail is strong, the impact force can be fullydissipated, an energy-dissipating steel plate composite structure and a light energy-dissipating material arranged in a collision-prevention device and extruding each other can provide stable dampingforce, shock absorption and energy-dissipating capacity through the impact force acting on the collision-prevention device. The energy-dissipating steel plate composite structure has good coordinationand connection performance, can disperse and transmit the impact force, and can significantly improve the energy dissipation efficiency. The guardrail has good application effect, strong practicability, more convenient assemblage, and can be replaced well if damaged, has the ability to protect the vehicle against collision and damage, and the service life of the guardrail can be greatly increased.

Description

technical field [0001] The invention belongs to the field of road traffic facilities, and in particular relates to an assembled reinforced protective isolation guardrail. Background technique [0002] With the development of the national economy, a large number of roads and expressways have been built or are under construction. At present, the guards on both sides of the expressway and the road are made up of columns and a guard plate positioned on its top, and the guard plate is made of steel plates, both of which are rigid materials and are rigidly connected. When the car loses control and hits the protective plate, the protective device can prevent the car from turning into the waterproof ditch on both sides of the expressway or rushing into the opposite lane to crash. But practice has proved that the protective plate of the above structure has no cushioning function. Under the high-speed and powerful impact of an out-of-control car, the protective plate will often be br...

Problems solved by technology

At present, the existing guardrails on the market do not have the function of cushioning and shock absorption when they are in use. When a car hits the guardrail, it can only rely on the deformation of the guardrail to damage the energy absorption, and the deformation and energy absorption capabilities are limited.

And the guardrail board is easy to break under the impact of the car, causing the guardrail to be unable to use normally, and it is also easy to cause secondary damage to the safety of the vehicle and the crew. In summary, how to solve the deformation ability and energy absorption of the existing highway guardrail The problem of limited ability has become a problem that those skilled in the art need to solve
