[0002] Traditional traffic safety guardrails are mainly made of stone piers or columns plus M-shaped steel plates. Their structural strength, hardness or buffering force are low, and it is difficult to block and protect cars when they lose control and crash into traffic safety guardrails. Some more dangerous roads, such as expressways, winding mountain roads, and sections with high traffic and pedestrian flow, require very high strength, hardness and buffering capacity of traffic safety guardrails; if the above performance indicators of traffic safety guardrails are low, out-of-control cars can easily crash through the guardrails, and if they are on expressways or winding mountain roads, they may fall into dangerous places such as cliffs, woods, rivers, etc., and if they are on sections with high traffic and pedestrian flow, they are likely to collide with pedestrians and other vehicles.

[0003] When using the guardrail, it is generally necessary to fix the guardrail. At present, the guardrail is usually fixed directly to the ground with expansion bolts, but this kind of guardrail is only fixed vertically to the ground. The guardrail is prone to loosening when it is hit by external impact, which reduces the stability of the guardrail and greatly reduces the protective performance of the guardrail.

[0039] refer to Figure 1-Figure 3As shown, when the traffic safety guardrail of the utility model is in use, the column leg 2 is first vertically inserted into the ground. Due to the guidance of the conical tip 21 on the column leg 2, the column leg 2 can be easily inserted into the ground, completing the vertical fixation between the column 10 and the ground, and then the hexagonal head 311 on the driving member 31 is screwed to drive the screw 312 and the adapter 313 to move downward, and then drive multiple limit blocks 33 to extend out of the side wall of the column leg 2 and insert into the ground through multiple transmission rods 32. Due to the guidance of the wedge-shaped structure on the limit block 33, the limit block 33 can be easily inserted flat into the ground, completing the horizontal fixation between the column 10 and the ground, thereby completing the installation between the traffic safety guardrail and the ground. When the traffic safety guardrail needs to be removed, first screw the hexagonal head 311 on the driving member 31 to drive the screw 312 and the adapter 313 to move upward, and then drive the multiple limit blocks 33 to retract into the column leg 2 through the multiple transmission rods 32, so as to release the horizontal fixation between the column 10 and the ground, and then pull the column leg 2 vertically upward out of the ground to release the vertical fixation between the column 10 and the ground, so that the traffic safety guardrail can be removed from the ground.
