Description

Technical Field

[0001] The utility model relates to a traffic isolation guardrail. Background Art

[0002] As an important traffic facility, traffic isolation guardrails are widely used in the isolation belt in the middle of the road, the separation, protection and guidance of sidewalks and roadways. Its main function is to ensure driving safety and reduce the occurrence of traffic accidents. However, the existing traffic isolation guardrails have some technical defects during use, which makes it unable to fully play its expected role in actual application.

[0003] Traditional traffic isolation guardrails are usually made of metal materials, such as steel and aluminum alloy. Although these materials have high strength and durability, they are very rigid and cannot effectively cushion and absorb shock when vehicles collide, resulting in vehicles still being severely damaged in the event of a minor collision. Especially when driving at high speeds, a collision between a vehicle and a guardrail may lead to serious consequences, not only causing damage to the vehicle, but also endangering the lives of the driver and passengers.

[0004] In addition, existing traffic isolation guardrails are usually made up of multiple components, and the installation process is complicated and time-consuming. There are various ways to connect the guardrail posts and railings, some of which are fixed by welding, and some are connected by bolts. Although these connection methods can ensure the stability of the guardrail, in actual use, once the guardrail is damaged, it is often necessary to disassemble a large number of components when it needs to be repaired or replaced, which is cumbersome and labor-intensive. In addition, the welded guardrails also require the use of professional welding equipment and technology when repairing, which further increases the difficulty and cost of repair.
