Quick assembly highway buffer guardrail

Abstract

The invention discloses a fast-assembling expressway buffer guardrail, which comprises: a plurality of bases, which are evenly spaced and arranged on both sides of the expressway; a baffle; a plurality of uprights, which are set in one-to-one correspondence with a plurality of bases; a plurality of elastic buffer tubes, which are hollow cylinders with openings at both ends, and a plurality of elastic buffer tubes are sleeved on the plurality of uprights in one-to-one correspondence; and The guardrail board is horizontally hung on the outer wall of multiple elastic buffer tubes on the side facing the road surface of the expressway. The present invention realizes the rapid assembly of highway buffer guardrails through rationally arranged multiple bases, multiple pillars, multiple elastic buffer tubes and guardrail panels, and the structure of multiple elastic buffer tubes and guardrail panels has a good buffering and energy-absorbing effect .

Description

Technical field [0001] The present invention relates to the field of guardrail technologies, and in particular, there is a rapid assembly highway buffer fence. Background technique [0002] With a large amount of construction and global car ownership, the incidence of traffic accidents has also shown an increase in the incidence of traffic accidents. At present, the protective device on both sides of the highway is mainly composed of a postage and a bail plate, the column and the bail plate are rigid materials. The car hits the bail plate, which can only rely on the deformation of the fence plate, deformation. Ability and the ability to absorb energy are limited. And the bail board is easily broken under the impact of the car, and it is easy to cause secondary injury to the safety of vehicles and passensities. In addition, when a traffic accident causes a serious damage to the fence, due to the structural restriction, the installation fee is laborious, the labor intensity is high...

AI Technical Summary

Problems solved by technology

At present, the protective devices on both sides of the expressway are mainly composed of uprights and guardrails on top of them. Both the uprights and the guardrails are made of rigid materials. When a car hits the guardrails, it can only rely on the deformation of the guardrails to damage energy absorption and deform Limited capacity and ability to absorb energy

And the guardrail is easy to break under the impact of the car, and it is easy to cause secondary damage to the safety of the vehicle and the crew.

In addition, when a traffic accident causes serious damage to the guardrail, due to structural limitations, the installation is time-consuming, labor-intensive, and low-efficiency, which not only cannot guarantee the safety of other vehicles, but also directly affects the appearance of the road surface
