Collision-proof and vehicle fall-proof device of bridge and capable of buffering impact

Abstract

The invention discloses a collision-proof and vehicle fall-proof device of a bridge and capable of buffering impact. The device comprises a bridge concrete pavement layer and an overhang bearing plate. The bridge concrete pavement layer is provided with a sandwich layer, which is used for receiving the overhang bearing plate; two sliding layers are arranged in the bridge concrete pavement layer, and the overhang bearing plate is arranged between the two sliding layers, so that the overhang bearing plate can freely slide in the bridge concrete pavement layer; the outer end of the bridge concrete pavement layer is provided with an anti-dropping blocking part, and the rear end of the overhang bearing plate is provided with a blocking part, so that the anti-dropping blocking part can form blocking of the overhang bearing plate and prevent the overhang bearing plate from being separated from the bridge concrete pavement layer in the process of outward movement; a buffering device is arranged on the inner side of the anti-dropping blocking part, when the vehicle strikes a guardrail, the buffering device is struck by the blocking part of the overhang bearing plate, and under the action ofthe buffering device, a strong impact force is relieved and released, thereby playing a buffering role on the vehicle and ensuring the safety of the vehicle.

Description

technical field [0001] The invention relates to the field of traffic safety facilities, in particular to a bridge anti-collision and anti-fall vehicle device capable of buffering impacts. Background technique [0002] With the rapid development of transportation infrastructure in various countries in the world, there are more and more roads with high proportion of infrastructure such as overpasses, viaducts, cross-sea bridges and other bridges. At the same time, the number of vehicle accidents caused by various reasons is also increasing year by year. The death rate of such accidents is extremely high, so it has become a problem of widespread concern in the society, such as the "10.28 Chongqing Wanzhou District Bus Falling into the River Accident", "Hubei Jingzhou Bus Falling into the Bridge Accident", "Shaanxi Tongchuan Vehicle Falling into the Bridge Accident" and other vehicles In the bridge accident, the casualties were very serious, and almost no one survived.

AI Technical Summary

Problems solved by technology

[0003] The reason why the vehicle hits the guardrail and rushes out of the bridge is complicated, and it is difficult to avoid such accidents

At present, the main method adopted by countries in the world in bridge anti-collision and anti-fall vehicles is to set up corresponding grades of guardrails, but at present, it is difficult for bridge guardrails to deal with both collision and fall accidents. If the strength level of bridge guardrails is low, it is easy for vehicles to crash the guardrails , rushing out of the bridge, but if the height of the bridge guardrail bridge is higher, it is prone to serious vehicle damage and serious passenger casualties
