Description

Technical Field

[0001] The utility model relates to the technical field of concrete anti-collision guardrail maintenance, in particular to a protective device for concrete anti-collision guardrail. Background Art

[0002] Concrete crash barriers are safety facilities used on the edge of roads or bridges, designed to reduce serious accidents caused by vehicles accidentally leaving the road. This type of guardrail is usually made of concrete blocks or concrete components. The maintenance of concrete crash barriers on bridge decks is difficult, and they are close to the river, with strong winds. The concrete surface of the concrete guardrail loses water quickly, and the surface of the crash barrier is prone to many shrinkage cracks, and there are many quality problems. During the construction of the crash barriers on the lower first-level highway, the frame piers and segmental beams of the upper highway are also being constructed simultaneously. Equipment oil, concrete and grouting materials can easily fall onto the lower bridge deck and pollute the crash barriers.

[0003] Traditional concrete anti-collision guardrails are covered with geotextiles and watered for maintenance. If workers fail to water in time or the geotextiles are dried out by strong winds, cracks will occur on the concrete surface. In addition, the frame piers and segmental beams of the upper highway are also being constructed simultaneously. Equipment oil, concrete and grouting materials can easily fall onto the lower bridge deck and pollute the anti-collision guardrails. Therefore, a protective device for concrete anti-collision guardrails is needed to improve the above problems. Utility Model Content
