Problems solved by technology
However, for high-risk road sections with large curves, dark ice, and slippery road surfaces, due to the high driving risk, it is easy to slip and deviate from the lane. Due to its limitations, this simple guardrail often cannot be used Very good protection effect, increasing the hidden danger of driving safety
In addition, theoretically speaking, the main body of the guardrail should be used as the last barrier in the process of driving protection, and its own impact resistance should be further strengthened. Compared with the traditional straight guardrail, its impact resistance has been improved to a certain extent, but it still has a certain risk of fracture under high-intensity impact, and its impact resistance strength needs to be improved

Embodiment Construction
[0029] Such as Figure 1-11 The impact-resistant expressway guardrail shown is mainly installed on large curves, slopes, wet and slippery roads, dark ice and other road sections, and is used to protect the driveway. Compared with the traditional driveway guardrail box, the present invention also includes a guardrail 1 arranged on the edge of the lane 0 and extending along the length direction of the lane 0. The guardrail 1 includes a number of columns 2 distributed at intervals and a guardrail body arranged on the columns 2 3. The column 2 is used as the installation base, and the main body of the guardrail 3 is used as the main structure of the enclosure.
[0030] Compared with the traditional simple guardrail, the present invention has a big difference in that the side of the guardrail body 3 close to the lane 0 is evenly distributed along the length direction of the guardrail body 3 for directly bearing the impact of the vehicle. Impulsive rotating components. As the nam...

The invention relates to the technical field of protective fences and aims to provide an impact-resistant highway protective fence comprising a protective fence body which is arranged on the edge of a lane and extends in the length direction of the lane, and the protective fence body comprises a plurality of stand columns distributed at intervals and a protective fence body arranged on the stand columns; the cross section of the protective fence body is in a bow shape, and a plurality of reinforcing plates is distributed in a first groove in the outer side of the middle of the protective fence body at intervals in the length direction of theprotective fence body. A flexible supporting assembly is further arranged in the first groove. The flexible supporting assembly comprises a supporting steel cable and a plurality of flexible supporting blocks. The reinforcing plate is provided with a cable hole penetrating through the reinforcing plate in the transverse direction, and a supporting steel cable is arranged in the cable hole in a penetrating mode. The shock resistance of the protective fence body can be greatly improved, the protective fence body is prevented from being broken, and the driving risk is reduced.
Description
technical field [0001] The invention relates to the technical field of guardrails, in particular to an impact-resistant expressway guardrail. Background technique [0002] Highway guardrail is a protective device used to protect the lane and prevent vehicles from rushing out and deviating from the lane. It can protect pedestrians and vehicles and reduce accident losses. At present, the traditional highway guardrail is a steel railing with a C-shaped or 3-shaped cross-section of the main body of the guardrail formed by stamping, bending, etc. When this kind of railing has a collision accident, because the main body of the guardrail has a relatively large rigidity, although the impact can be buffered to a certain extent through its deformation, the buffering effect is not good. More harmful. However, its advantage lies in its simple structure and low cost, and it is suitable for long-distance laying on the main road with low driving risk on the expressway. However, for high...
