Embodiment Construction
[0026] Such as Figure 1-7 As shown, a high-speed highway protection device with good safety, and a traditional high-speed guardrail box, both include a number of installation columns arranged on both sides of the road and a guardrail main body 1 arranged on the installation columns. The installation columns are distributed along the length direction of the road on both sides of the road, and the guardrail main body 1 is arranged on the installation columns and extends along the length direction of the road, so as to guide and protect the road. Generally speaking, the guardrail body 1 is made of traditional high-speed guardrail material, and is covered with anti-corrosion paint and other coatings.
[0027] Compared with the traditional high-speed guardrail, the present invention is different in that, as figure 1 and 2 As shown, the cross section of the guardrail body 1 is in the shape of a "3", and the opening faces away from the center of the road. That is to say, the two ...

The invention relates to the field of highway protection, and aims at providing a highway protection device with high safety. The highway protection device comprises a plurality of installation columns arranged at the two sides of a road and a guardrail body arranged on the installation columns. The cross section of the guardrail body is 3-shaped, and an opening of the guardrail body is opposite to the center of a road; a warning lamp strip extending in the length direction of the guardrail body is arranged in a first groove in the outer surface of the 3-shaped middle section of the guardrail body; and buffering air bags extending in the length direction of the guardrail body along the guardrail are arranged in an upper second groove and a lower second groove in the 3-shaped guardrail body, and each buffering air bag is formed by sequentially connecting a plurality of bag bodies. According to the invention, collision accidents can be quickly warned in time through the guardrail body, a prompt effect for rear vehicles is achieved, secondary and tertiary accidents are avoided, and the safety of high-speed driving is improved.
Description
technical field [0001] The invention relates to the field of highway protection, in particular to a safe highway protection device. Background technique [0002] Highway guardrails are installed on both sides of the expressway lane to act as a blocking protection. On the one hand, the highway guardrail can provide final restraint for vehicles in accidents, preventing vehicles from rushing out of the lane and causing more serious accidents; On the other hand, it also plays a role in buffering collisions, absorbing collision energy as much as possible, and reducing personal injuries to drivers and passengers. [0003] As we all know, the occurrence of traffic accidents is sudden, and because of its suddenness, the following vehicles often collide with the accident vehicles and accident debris in front without warning, causing secondary or even multiple accidents. As a continuous equipment and facility on the highway, the guardrail naturally has the advantage of being a good c...
