Abstract

The invention provides a buffering anti-collision structure used in roads and intersections. The buffering anti-collision structure comprises telescopic buffering guardrails, telescopic buffering guardrail groups, telescopic buffering crossbeams, elastic rotating devices and third constant tension separating devices, wherein one or more telescopic buffering guardrail groups are mounted between every two adjacent pillar assemblies; each of the telescopic buffering guardrail groups is formed by the sequential connection of the telescopic buffering guardrails; each of the pillar assemblies is connected with an embedded base through the corresponding telescopic buffering crossbeam; and each of the third constant tension separating devices is also mounted on the corresponding telescopic buffering crossbeam. According to the buffering anti-collision structure disclosed by the invention, when an automobile which is out of control decelerates, the guardrails are used for stabilizing the deceleration of the automobile which is out of control, and the direction of the telescopic buffering crossbeams can be adjusted, so that the telescopic buffering crossbeams can decelerate according to the travelling direction of the automobile which is out of control.

Description

technical field [0001] The invention relates to the technical field of road safety protection, in particular to a buffer and anti-collision structure at roads and crossings. Background technique [0002] With the rapid development of traffic construction such as highways and bridges in our country, the transportation capacity has been greatly improved. However, the number of cars in our country is also increasing rapidly, and consequently, the traffic accidents of vehicles colliding with guardrails in roads and bridges are also increasing, causing the situation of driving off the road, falling into the ramps on both sides and falling into the bridge is not uncommon. , resulting in huge casualties, property damage and environmental damage. In order to minimize the severity of traffic accidents and prevent cars from crossing the road, it is an important project for road safety to set up safety guardrails. The guardrail should have the following safety performance indicators:...
