[0002] Guardrails are mainly used for the protection of personal safety and equipment in places such as residences, highways, commercial areas, and public places.

[0003] In the prior art, guardrails are installed on both sides of the road to separate the motor vehicle lane and the non-motor vehicle lane. Columns are installed at both ends of the guardrail, and an embedded base is installed at the bottom end of the column. After the embedded base is buried in the ground, the firm installation of the guardrail column is realized.

[0004] However, the contact area between the traditional embedded base of the guardrail column and the soil layer is limited. That is, after the embedded base is buried in the soil layer, when the guardrail column is collided, the embedded base is driven to tilt and pull out from the soil layer, which affects the firmness of the installation of the guardrail column.
