Self-adaptive deformation reset anti-collision method capable of resisting uneven impact force

Abstract

The invention provides a self-adaptive deformation reset anti-collision method capable of resisting uneven impact force. A self-adaptive viscous damping anti-collision pier is arranged on the foundation, the anti-collision pier comprises a main structure and a rigid framework embedded in the main structure, a viscous damping chamber is arranged in the rigid framework, a piston with a damping holeand a spring abutting against the piston are arranged in the viscous damping chamber, and the tail end of a piston rod extends out of the rigid framework and is connected with a collision plate in a hinged mode. During collision, the collision plate enables a viscous liquid to flow through the damping hole to consume collision energy. The collision plate can be subjected to tipping movement in various directions when bearing eccentric collision impact, and the anti-collision pier can automatically adapt to the situation of eccentric collision. After the collision occurs, the collision plate can be automatically reset under the action of the spring. During manufacturing of the anti-collision pier, the rigid framework is firstly manufactured, a liquid injection hole is drilled in the rigid framework, and then the rigid framework is integrally cast with the main body structure, the anti-collision pier is simple and convenient, the practicability is strong, and the economical efficiency isgood. The method is particularly suitable for bridge abutments, bridge bodies, mountain roads and the like.

Description

technical field [0001] The invention relates to the field of road transportation infrastructure, in particular to an anti-collision method capable of resisting uneven impact force and self-adaptive deformation reset. Background technique [0002] In recent decades, my country has increased investment in infrastructure such as urban and rural road construction, expressway and railway construction, and my country's road transportation has developed rapidly, driving the development of urban and rural economies and boosting people's income. With the improvement of the level, the number of private cars in our country continues to increase. Setting anti-collision guardrails or anti-collision piers on both sides of the road is one of the most important safety measures for road driving, especially for sharp bends, slopes, bridges, mountains and waterfronts. On dangerous road sections such as cliff roads, the protective effect of the anti-collision guardrail or anti-collision pier dire...

Problems solved by technology

On the one hand, existing metal anti-collision guardrails have insufficient structural strength, and accidents that cause car crashes and fatalities occur from time to time when automobiles (especially large passenger and freight cars) crash into the guardrails, and existing metal anti-collision guardrails are Most of them will be severely deformed and irreversible after being impacted once, and need to be rebuilt and repaired, which is time-consuming and labor-intensive; on the other hand, many existing concrete anti-collision columns are too rigid, which is easy to cause secondary damage such as rebounding of the vehicle; On the one hand, in most road conditions, especially on sharp curves and slopes, the collision between the vehicle and the anti-collision pier on the roadside is not a frontal collision, but an oblique collision with eccentricity. If the stiffness of the anti-collision pier itself is too large, Then the reverse impact energy to the vehicle will be too large, and the vehicle is prone to secondary rotation or even overturning, which seriously threatens the life safety of the people in the vehicle. Therefore, in the prior art, a higher safety performance anti-collision pier is needed to solve this problem
