Description

Technical Field

[0001] The invention relates to the technical field of bridge maintenance spraying, and in particular to an automatic spraying maintenance system for cantilevered beam sections of rigid frame bridges. Background Art

[0002] Cantilevered beam sections, particularly in steel bridges, refer to those constructed using the cantilever casting method. This method involves setting up work platforms on either side of the piers to cantilever the cement concrete beam section by section, balanced and prestressed towards the mid-span. This method allows the bridge beam sections to be gradually extended until the entire span is complete. Construction of the cantilevered beam sections is carried out piecemeal, with each section being cast based on the previous one. This construction method allows the bridge beam section to be gradually extended until the entire span is complete. After pouring, the concrete requires time to harden and gain strength. During this process, if the concrete surface loses water too quickly, it can easily crack. Spray curing, by applying a water mist to the concrete surface, creates a moist protective film that effectively slows the evaporation of water and prevents cracking.

[0003] Among them, patent publication number CN210127197U discloses an intelligent automatic spray maintenance system for cantilevered beam sections of continuous rigid frame bridges. The system includes a water tank installed on the bridge deck, which is connected to a main water pipe via a booster pump. The main water pipe is connected to spray pipes installed on hanging baskets at both ends of the bridge deck. The spray pipes are installed on the front upper crossbeam, inner sliding beam, and outer sliding beam of the hanging baskets.

[0004] When this structure is in use, spray maintenance can be achieved on the bridge deck, inner box bottom plate, top plate and web, as well as the bottom surface of the flange plate and the outer surface of the web by installing spray pipes on the hanging basket components, namely the front upper cross beam, the inner sliding beam and the outer sliding beam. The system is not affected by human factors, has comprehensive maintenance, and does not pose a risk of high-altitude operation. However, when this structure is in use, it is not easy to spray and maintain the cantilever beam sections in different areas, and it is not easy to adjust the appropriate range according to demand during spraying, which is not convenient enough to use. Summary of the Invention

[0005] The present invention provides an automatic spraying and curing system for cantilevered beam sections of rigid frame bridges, aiming to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: an automatic spraying maintenance system for cantilever beam sections of rigid frame bridges, comprising a support rail, and a regulating spraying assembly is provided at the bottom of the support rail.
