Highway protective device

Abstract

The invention relates to the field of highway facilities, in particular to a highway protective device. The highway protective device comprises multiple mutually connected protective separate bodies, each protective separate body comprises an upper layer protective device, support devices are arranged on the bottoms of the two sides of the upper layer protective device, a bottom fixture arranged below a foundation is arranged at the bottom of each support device, the adjacent upper layer protective devices of the protective separate bodies are connected through buffer connecting devices, and the bottom fixtures of the adjacent protective separate bodies are fixedly connected to the foundation through fastening connection devices. The highway protective device is simple in structure and reasonable in design and can play a role of warning drivers during daytime and nighttime through a warning board, by means of the protective separate bodies, the protective and buffer effects on a vehicle can be achieved when the vehicle strikes the device, the requirements of people are effectively met, and the problems existing in the prior art are solved.

Description

Technical field: [0001] The invention relates to the field of highway facilities, in particular to a highway protection device. Background technique: [0002] At present, guardrails are usually set up on the expressway to play a safety role. When a high-speed vehicle runs out of control and hits the guardrail of the expressway, the guardrail can block or partially offset the impact caused by the impact through its own deformation. Huge damage force, although the current guardrail has a certain effect in preventing excessive displacement of vehicles, but when the vehicle is driving, the existing guardrail cannot effectively warn the vehicles on the road. It can play a protective role after the accident, not only cannot effectively reduce the probability of accidents, but also because the current guardrail is usually made of steel with high rigidity and strength, its structure is very simple, the material hardness is relatively high, and at the same time it is brittle It is a...

[0002] At present, guardrails are usually set up on the expressway to play a safety role. When a high-speed vehicle runs out of control and hits the guardrail of the expressway, the guardrail can block or partially offset the impact caused by the impact through its own deformation. Huge damage force, although the current guardrail has a certain effect in preventing excessive displacement of vehicles, but when the vehicle is driving, the existing guardrail cannot effectively warn the vehicles on the road. It can play a protective role after the accident, not only cannot effectively reduce the probability of accidents, but also because the current guardrail is usually made of steel with high rigidity and strength, its structure is very simple, the material hardness is relatively high, and at the same time it is brittle It is also large. When receiving an excessive impact force, the change of its critical tension mainly depends on the properties of the steel material. The structure and design characteristics of the existing guardrails also lead to the fact that the existing guardrails can only play a role in the process of use. However, this protection method will not only increase the degree of damage to the vehicle itself after the vehicle is hit, but also hardly protect and guarantee the life safety of the driver and passengers in the vehicle. Obviously, the existing Highway guards fail to meet people's needs more effectively
