Description

Technical Field

[0001] The present application relates to the field of maintenance and coating, and in particular to an automatic spraying maintenance device for thin-walled guardrails and a spraying method thereof. Background Art

[0002] Reinforced concrete anti-collision guardrails, also known as thin-walled guardrails, are an important road safety facility. They are mainly installed on both sides of the highway or on the central dividing strip, which can effectively reduce the occurrence of traffic accidents and ensure the safety of vehicles and passengers. This guardrail is designed to absorb and disperse the impact force from the vehicle. When a vehicle hits the guardrail, due to the special structure of the guardrail, the vehicle will be guided to a safe position, thus avoiding the occurrence of secondary accidents.

[0003] In order to ensure the normal operation of reinforced concrete anti-collision guardrails, regular maintenance and upkeep are required for the guardrails. Thin-walled guardrails need to be repaired after cracking or collision during use. After repair, they are usually covered with geotextiles. The geotextiles are regularly sprinkled with water by hand or by a sprinkler truck to keep the guardrail moist for maintenance, reduce cracks on the surface of the guardrail, and ensure that the later strength of the guardrail meets the requirements. Personnel need to be regularly arranged to sprinkle water for maintenance to ensure the stable growth of concrete strength and avoid shrinkage cracks. However, in hot weather, the temperature is high and the water evaporates quickly. Manual maintenance requires continuous watering, which results in low maintenance efficiency. In addition, it is difficult to properly maintain the guardrail when it is in the air, resulting in the inevitable slow strength growth and even shrinkage cracks on the air-facing surface. Quality defects. Manual maintenance or sprinkler trucks take a long time, and maintenance costs increase. Summary of the invention
