specific Embodiment

[0036] Such as Figures 1 to 6 As shown, the prefabricated segmental box girder spraying maintenance system includes a support base, a mobile frame, a horizontal section of the box girder, a spraying frame on the side wall of the box girder, and a water supply component.

[0037] Specifically, such as figure 1 with figure 2 As shown, the supporting platform includes a supporting platform 2 for supporting a prefabricated segmental box girder 3 on which a supporting base body 1 is arranged. The length direction of the support base 1 is defined as the front-to-back direction, and the width direction is the left-right direction. The support base 1 is provided with a water tank 6 surrounding the support platform 2 at a position connected to the support platform 2 . The water tank 6 has the same shape as the playground when viewed from above, including a rectangular area and a semicircular area located at two ends of the rectangular area. Such as Figure 5 As shown, in the sect...

Abstract

The invention relates to a spraying maintenance system for a prefabricated segment box girder, and relates to the field of concrete prefabricated part maintenance. The spraying maintenance system for the prefabricated segmental box girder comprises a supporting pedestal, a movable frame, a box girder horizontal segment spraying frame, a box girder side wall spraying frame and a water supply assembly; the supporting pedestal comprises a supporting base body and a supporting table, and a water flowing groove surrounding the supporting table is arranged at the position, connected with the supporting table, of the supporting base body; the movable frame is movably assembled on the supporting pedestal, a top spraying pipe is installed on the movable frame, the box girder horizontal section spraying frame comprises a plurality of connecting rods which are arranged in the supporting table and arranged at intervals in the front-back direction, and horizontal spraying pipes are installed at the left end and the right end of each connecting rod; the box girder side wall spraying frame comprises a spraying frame body pre-buried in the supporting pedestal and a side wall spraying head mounted on the spraying frame body; and the water supply assembly comprises a water supply tank and a water supply main pipe connected with the water supply tank. Spraying maintenance can be comprehensively conducted on the prefabricated segmental box girder, the maintenance difficulty is lowered, and water resources can be recycled and reused.

Description

technical field [0001] The invention relates to the field of maintenance of concrete prefabricated parts, in particular to a spray maintenance system for prefabricated segmental box girders. Background technique [0002] After concrete is poured, the reason why it can gradually set and harden is mainly due to the result of concrete hydration, and hydration requires appropriate temperature and humidity conditions. After the concrete is poured, if the climate is hot and the air is dry, if the water in the concrete is not sprayed and cured in time, the water in the concrete will evaporate too quickly, so that the cement particles that have formed a gel cannot be fully hydrated and transformed into stable crystals. Cohesion, so flakes or powders will fall off on the concrete surface. In addition, when the concrete does not have sufficient strength, the premature evaporation of water will also cause large shrinkage deformation and dry shrinkage cracks, which will affect the dura...
