[0002] At present, with the rapid development of my country's economy and modernization construction, many in-service roads can no longer bear the current traffic flow. Under the background of dual carbon, the reconstruction and expansion of existing in-service roads in busy traffic sections has its unique advantages of saving land, saving resources and strengthening the main functions of highways. my country's highway construction has gradually transitioned from pure new construction to a construction situation that emphasizes both new construction and reconstruction and expansion, and the proportion of reconstruction and expansion roads has increased year by year. The widening and reconstruction of the original highway is often implemented under the condition of not interrupting traffic. While ensuring the safe operation of traffic flow, it is necessary to ensure the safety of construction workers. However, during the pavement construction process, the guardrail cannot be anchored to the pavement and needs to be able to move at any time. When ordinary guardrails are not anchored to the ground, their own stability is poor, the connectivity between ordinary guardrails is poor, and there is basically no anti-collision buffering ability.
