AI Technical Summary
Existing reinforced concrete guardrails on bridges are prone to damage when exposed to corrosive environments for extended periods, resulting in corrosion pits, peeling of the protective layer, and rusting of the reinforcing bars. This leads to high maintenance costs and occupies bridge deck space, making it difficult to meet traffic operation requirements.
A boot-type waterproof curing device for bridge concrete guardrails is adopted, which includes a mobile platform, a grouting system and a boot-shaped metal mold. The device uses high-pressure spraying of waterproof grout and vibrators to ensure dense and uniform distribution, thereby achieving rapid waterproof curing.
It extends the service life of reinforced concrete bridge railings, reduces maintenance costs, avoids environmental pollution, and optimizes the use of bridge deck space.
