At the same time, attention should be paid to construction management and maintenance management. In the construction of rural roads, stone pier safety guardrails are needed.

[0003] However, the existing technology still has the following problems:

[0004] First of all, for the stone pier safety guardrails used in the construction of rural roads in the existing technology, most of the guardrail structures are relatively simple and not firm enough. They may just be some simple splicing or welding, and are easy to loosen or deform when subjected to external force impacts, resulting in the overall structure of the guardrail not being stable enough to withstand external force impacts such as vehicle collisions well, and thus being easily damaged, shortening the service life of the guardrail.

[0005] Secondly, for the stone pier safety guardrails used in the construction of rural roads in the existing technology, most of them are not convenient to rotate the angle. Traditional rural road guardrails may be of a fixed shape and angle, which leads to difficulties in well adapting to different shapes, slopes, or curves of rural roads. Complex customization or transformation may be required, increasing the cost and construction difficulty, and their own versatility is relatively low, and they cannot flexibly meet the actual needs of various rural roads.

[0006] In view of the above problems, the inventor proposes a stone pier safety guardrail for rural road construction to solve the above problems. Content of the Utility Model
