The invention relates to a buffering pipe for a road guardrail. The buffering pipe comprises an inner pipe and an outer pipe. An annular magnet wraps the outer surface of the inner pipe, an electromagnet with the magnetic poles opposite to those of the annular magnet is fixedly connected to the inner surface of the outer pipe, a gap exists between the outer surface of the annular magnet and the inner surface of the electromagnet, the inner pipe and the outer pipe are fixedly connected through a plurality of rubber supports, an infrared induction device used for controlling the electromagnet is fixedly connected to the wall of the outer pipe, and a power device used for supplying power to the infrared induction device and the electromagnet is arranged on the wall of the outer pipe. According to the buffering pipe for the road guardrail, the electromagnet with the magnetic poles opposite to those of the annular magnet is fixedly connected to the inner surface of the outer pipe, so that the impact force is effectively reduced, and the safety of the guardrail is improved.
