Highway reinforced protective fence

Abstract

The invention discloses a highway reinforced protective fence, which comprises a trapezoidal base, a base column is movably connected to the top of the trapezoidal base, a protective fence body is movably connected to the end, away from the trapezoidal base, of the base column, and a top base column is movably connected to the top, away from the base column, of the protective fence body; the ends, away from the guardrail body, of the top seat columns are movably connected with transverse rods, and the sides, away from the top seat columns, of the transverse rods are movably connected with protection pads. The guardrail body comprises a clamping outer ring mechanism, and the top and the bottom of the inner surface of the clamping outer ring mechanism are movably connected with inner strengthening mechanisms. Through the multilateral design of the inner strengthening mechanism, the balance and stability of the part during dumping are improved, the collided vehicle is directionally limited, non-directional swing of the collided vehicle is avoided, the surrounding safety is protected, the contact region between the collided vehicle and the ground is increased, the speed reduction effect is improved, the braking energy of the vehicle is strengthened, and the safety performance is improved.

Description

technical field [0001] The invention relates to the technical field of highways, in particular to a reinforced protective fence for highways. Background technique [0002] The protective structure of the safety guardrail beside the existing road is generally a protective plate, and the protective plate is mostly bent to form an arc-shaped plate structure by metal materials. The arc-shaped plate structure can provide a certain buffer force to reduce impact damage. [0003] According to the Chinese patent CN112160275A, no welding is required in the whole process, and the assembly efficiency is high; when it is necessary to replace several extension springs, it is only necessary to take out the two rectangular strips and several extension springs from the cavity, which is convenient and efficient; The upper and lower sides of the front fence and the upper and lower sides of the rear fence are preset with outward tension, so that the upper and lower ends of the front fence can b...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a road reinforced guardrail, which solves the problem of the existing road reinforced guardrails being set in an arc shape when the front fence and the rear fence are in use, and their own balance performance after a collision. Poor, easy to tilt, causing it to guide the vehicle in a non-directional manner, difficult to control, and endangering the safety of the surrounding area
