Cast-in-place continuous box girder automatic spray curing system

Abstract

The invention discloses an automatic spraying and maintaining system for cast-in-situ continuous box beams. By the aid of the automatic spraying and maintaining system, the problem of difficulty in maintaining high-altitude cast-in-situ concrete box beams can be solved. The automatic spraying and maintaining system is characterized in that a first hanger rod (18) is arranged in a first beam surface center drain hole (6); a second hanger rod (25) is arranged in a second beam surface center drain hole (9), an in-box H-shaped steel guide rail (19) is arranged in a beam box (5), one end of the in-box H-shaped steel guide rail (19) is connected with the bottom of the first hanger rod (18), the other end of the in-box H-shaped steel guide rail (19) is connected with the bottom of the second hanger rod (25), an in-box professional crane suspension vehicle (20) is hung on the in-box H-shaped steel guide rail (19), a portal travel frame (21) is connected onto the in-box professional crane suspension vehicle (20), in-box maintaining shower nozzles (22) are uniformly distributed on the portal travel frame (21), and the in-box professional crane suspension vehicle (20) is electrically connected with an electric control box (38). The automatic spraying and maintaining system has the advantages that the box beam maintaining quality can be improved, and manpower and material resources can be saved.

Description

Technical field [0001] The invention relates to a water spray curing system for continuous beams cast by reinforced concrete, in particular to an automatic spray curing system for cast-in-place continuous box beams. Background technique [0002] In the process of high-speed railway viaduct construction, when it is necessary to cross an existing line, it is necessary to cast the bridge on-site through a hanging basket on the top of the pier. After pouring is completed, spray maintenance of the inner and outer walls of the bridge. Traditional spray maintenance is carried out by hand-held water guns for spray maintenance. There are problems of uneven spraying and untimely maintenance. Especially on the outer side of box beams, due to the high altitude, to achieve uniform spray maintenance, cranes are required. Lifting equipment has the disadvantages of high risk and high cost. Inadequate water spray maintenance of the cast box girder directly affects the quality of the bridge and l...

AI Technical Summary

Problems solved by technology

The traditional spraying maintenance is carried out by hand-held water guns, which has the problems of uneven watering and untimely maintenance, especially on the outer side of the box girder. Because it is at a high altitude, it needs a crane to achieve uniform watering maintenance. The lifting equipment has the defects of high risk and high cost, and the water spray maintenance of the cast box girder is not in place, which directly affects the quality of the bridge and buryes potential safety hazards in the future.
