Anchoring-free guardrail

The anchoring-free guardrail comprises a steel screen body, a containing cavity is formed in the steel screen body, a filling opening communicated with the containing cavity is formed in the steel screen body, and a counter weight is filled in the containing cavity. The steel screen body is filled with the counter weights, so that the friction force of the guardrail is increased, the guardrail does not need to be installed on a road surface in a drilling and anchoring mode, and a good protection effect is achieved. When no counter weight exists in the steel screen body, the steel screen body can be conveniently transferred. The counter weight can be made of water, silt and other materials, material taking and recycling are convenient, and the steel screen body is made of steel and can also be recycled.
