Damping safety structure anti-collision pier

Abstract

The invention discloses a damping safety structure anti-collision pier. The damping safety structure anti-collision pier comprises a protective shell, an outer damping rubber layer, an outer elastic steel plate, a middle damping rubber layer, an inner elastic steel plate, an inner damping rubber layer and an elastic buffering rubber pad which are sequentially arranged from outside to inside; an obvious guide mark in black and yellow check is arranged on the periphery of the protective shell, and multiple springs are distributed in the middle damping rubber layer. By means of the anti-collisiondevice of the structure, the own anti-collision guide mark, own resistance and own highly elasticoplastic deformation of the anti-collision pier are used effectively for reducing, dissipating and isolating vehicle impact force, so that a vehicle does not make practical collision contact with a protected structure, while a tunnel portal and fork distributing part structure is protected, damage toaccident vehicles is effectively reduced, and personnel casualties are reduced.

Description

technical field [0001] The invention relates to the technical field of traffic anti-collision, in particular to an anti-collision pier with a damping safety structure. Background technique [0002] As the growth rate of car ownership is significantly higher than that of highways and urban roads, road traffic safety in my country is not optimistic. Traffic safety accidents caused by cars hitting tunnel entrances, road forks, diversions, and ramps in front of toll stations occur frequently. If it is light, it will cause traffic jam, and if it is serious, it will cause tunnel collapse, car crash and death, which will bring irreparable loss of life and property. [0003] In contrast, anti-collision measures at tunnel entrances, road forks, and diversions still adopt traditional protection methods, such as installing anti-collision buckets (sand buckets) or using steel structure guardrails for protection. The structure failed to fundamentally buffer, dissipate, and reduce the imp...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problems that the protective facilities used at the entrances of traffic tunnels, diversions, forks, and ramps in front of toll stations lack anti-collision capabilities, have no guidance, are high in cost, and cannot be reused, the technical problem to be solved by the present invention is to provide a A kind of anti-collision pier with damping safety structure, which can effectively use the anti-collision guide mark, self-resistance, and high elastic-plastic deformation of the anti-collision pier to reduce, dissipate, and isolate the impact force of the vehicle without affecting the traffic of the vehicle. No actual collision and contact with the protected structure, while protecting the tunnel entrance and the diversion structure at the road fork, it can effectively reduce the damage of the accident vehicle and reduce the casualties
