Assembly type crash barrier special for road

Abstract

The invention provides an assembly type crash barrier special for the road and belongs to the road traffic facilities, reinforcing bases are arranged at the upper parts of reinforcing foundations, a crash barrier body structure which is defined by an upper sealing plate, a lower sealing plate, end plates and anti-crash protection mats is arranged at the upper parts of the reinforcing bases, lightouter package mild steel plates are arranged in the positions, close to the anti-crash protection mats, of the crash barrier body structure, a light energy dissipation material is arranged in the cavity of the crash barrier body structure, the upper sealing plate is arranged at the upper part, the lower sealing plate is arranged at the lower part, the anti-crash protection mats are arranged at the front and the back, the end plates are arranged on the two sides, concrete base plates are arranged in the crash barrier body structure, the lower parts of the concrete base plates penetrate throughthe lower sealing plate and are fixedly connected with the reinforcing bases, and a plurality of efficient energy dissipation arc-shaped mild steel plates are symmetrically arranged on the two sidesof the concrete base plates; the assembly type crash barrier special for the road has the advantages that mounting operation is simplified remarkably, the assembly speed is fast, the industrializationprocess is prompted favorably, the industrialized disassembly is very convenient, the anti-crash and damping coordinated energy-dissipating capacity is high, and the impact force can be fully dissipated.

Description

technical field [0001] The invention belongs to the field of road traffic facilities, in particular to an assembled anti-collision barrier for roads. 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 broken. People are mor...

AI Technical Summary

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
