Assembly type crash barrier connection system for sharp turn

Abstract

The invention provides an assembly type crash barrier connection system for a sharp turn, belonging to the field of road traffic facilities. A plurality of stand columns are arranged outside the sharpturn, two crooked connection handrails are arranged between two stand columns in the middle, a plurality of rotational energy consumption barrels are arranged between the two crooked connection handrails, two ends of the crooked connection handrails and the stand columns are connected and fixed, a plurality of connective fixing rods are arranged on the crooked connection handrails, outer barrelsand inner barrels are arranged in the rotational energy consumption barrels, rubber energy consumption layers are arranged between the outer barrels and the inner barrels, the internal spaces of the inner barrels are hollow areas, two ends of a light-weight energy consumption buffer guardrail plate and the stand columns are connected and fixed by connecting pieces, and a transitional connection rubber column is arranged between the light-weight energy consumption buffer guardrail plate and the rotational energy consumption barrel which is close to the light-weight energy consumption buffer guardrail plate; the beneficial effect is that the installation and operation of the system are remarkably simplified, the assembly speed is fast, the construction is simple, the construction cost is low, and the industrialized disassembly is quite convenient.

Description

technical field [0001] The invention belongs to the field of road traffic facilities, and in particular relates to a connection system for an assembled anti-collision barrier used in sharp curves. Background technique [0002] With the development of the national economy, a large number of roads and expressways have been built or are under construction. So at present, the protective devices on the outside of expressways and highways are basically made of ordinary protective guardrails, and the protective plates on the protective guardrails are made of steel plates, which are rigid materials. When the car loses control and hits the protective plate, the protective device can prevent the car from turning into the waterproof ditch on the outside 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 p...

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.
