Problems solved by technology

[0004] The existing highway guardrail has a single structure, and the anti-collision effect of the guardrail is not obvious. When the guardrail is damaged and needs to be replaced, the maintenance takes a long time and cannot be replaced quickly. For this reason, an asphalt road laying guardrail is designed to optimize the above problems

Abstract

The invention discloses a protective fence laid on an asphalt road, and belongs to the field of road traffic, the protective fence is buried underground through an embedded part, then a mounting plate is fixed on the ground through a locking screw penetrating through a mounting hole, and the arrangement of an anti-collision rod of a U-shaped structure and a spring shock absorber can play a role in shock absorption when the device is collided, the protective fence is protected from being damaged or the damage is reduced to the highest extent; after the protective fence, the stand columns and the steel wires or the springs are fixed into a whole, impact energy of an out-of-control vehicle can be absorbed, casualties and vehicle losses caused by the fact that the vehicle cannot be out of control rushes out of the road surface are prevented, and the elasticity of the steel wire ropes or the springs is reasonably set. An out-of-control vehicle can be controlled on a road, the vehicle is prevented from rushing out of the road, and the vehicle and passengers can be protected.

Description

technical field [0001] The invention relates to a highway protective fence, in particular to a protective fence for asphalt road laying, which belongs to the field of road traffic. Background technique [0002] With the development of my country's economy, road traffic is also growing. Both high-grade roads and expressways have been greatly developed. The development of roads has provided good conditions for transportation and greatly increased the speed of logistics. , shorten the material circulation time, and increase the speed of vehicles on the road. However, due to the increase in speed, the driver's fatigue driving during driving, frequent traffic accidents that are difficult to control, so how to avoid these accidents, especially how to ensure the safety of life is very concerned by the traffic department and the majority of drivers and passengers one question. [0003] Highway guardrail is the most important transportation infrastructure. my country's expressway wa...
