Assembly type light energy dissipation fence

Abstract

The invention provides an assembly type light energy dissipation fence and belongs to the field of road traffic facilities, the fence is formed by connection of a plurality of single crash barriers through vertical connection fixing piles, when the single crash barriers are connected, connection beams are fixedly connected with the vertical connection fixing piles, reinforcing foundations are arranged under the ground, reinforcing bases are arranged at the upper parts of the reinforcing foundations, the lower parts of the vertical connection fixing piles are fixedly connected with the reinforcing bases, a plurality of reinforcing steel bars are arranged in the reinforcing foundations and the reinforcing bases, and the reinforcing steel bars are anchored and connected through the concave connection stirrup. The assembly type light energy dissipation fence has the advantages that mounting operation is simplified remarkably, the assembly speed is fast, the industrialization process is prompted favorably, the construction cost is low, and industrialized disassembly is very convenient.

Description

technical field [0001] The invention belongs to the field of road traffic facilities, in particular to an assembled lightweight energy-consuming 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 broken. People a...

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
