Steel bridge deck pavement equipment

Abstract

The invention discloses steel bridge deck pavement equipment, and relates to the technical field of infrastructure for bridge engineering. The steel bridge deck pavement equipment comprises a rack, abase, a cleaning mechanism and a filling mechanism, an air injection device is installed at the upper end of the rack, the air injection device is connected with a vortex pipe through an air inlet pipe, and a first cavity and a second cavity are formed in the base. The cleaning mechanism is arranged in the base, and a plurality of shells rotate in the shell to make stubborn attachments on the inner walls of the cracks stirred and knocked off and blown out by high-speed airflow, and meanwhile, the interiors of the cracks can be completely cleaned in the deformation process that the shells are shrunk firstly and then increased, so the paving and repairing effects of the cracks are perfected; and by arranging the filling mechanism, a scraper is driven by a driving motor to scrape off redundant sealing glue and trowel a sealing glue, an embedded glue injection nozzle does not need to be poured, assembled and disassembled in a manual mode, and paving and decorating repair can be conducted quickly in a large range.

Description

technical field [0001] The invention relates to the technical field of infrastructure for bridge engineering, in particular to a steel bridge deck paving equipment. Background technique [0002] Steel bridge deck pavement mainly adopts two structural methods, including double-layer SMA structure and epoxy asphalt concrete structure, but no matter what paving method is adopted, cracks will inevitably appear after a long time. Continue to expand. In the prior art, the way of sealing and filling glue is usually used for paving. The specific operation is: manually cut out V-shaped grooves along the cracks with an angle grinder or direct sandblasting, and use a high-pressure air pump to blow out the internal dust, and then pre-embed Inject the glue nozzle and apply the sealing glue, and then directly pour the sealing glue after the leak test of the sealing seam, and manually use the sealing glue to level and polish the bridge base surface after filling.

AI Technical Summary

Problems solved by technology

[0003] During the long-term repair of bridge deck pavement, our company found that the existing technology still has certain disadvantages: 1. The high-pressure air pump can only blow out the dust attached to the inner surface of the crack and the dust deposited at the bottom, but for some stubborn attachments. It is not easy to blow out effectively, and because the cracks are not all vertical cracks or oblique straight cracks in the vertical direction, for the pavement layer with internal curved cracks, there are often debris such as stones larger than the bottom of the cracks (usually the size (2cm to 5cm) stuck in the middle of the crack, the high-speed airflow will bypass the stuck deposit, making it impossible to blow out, and once it remains inside the crack and the potting glue is poured, since the glue is not directly connected to the inner wall of the crack Contact, the weakening of the suction force will make it impossible to prevent the cracks from continuing to expand, or cavities will appear in the cracks after the sediment is loosened, and it will need to be paved and repaired again after a period of time; 2. Most of the cracks in the horizontal direction are curved, and the cracks are narrow Under certain circumstances, when pre-embedding the nozzle, the bottom hole is often not aligned with the crack, causing the potting compound to fail to fill the crack, and the pre-embedded nozzle needs to be disassembled again
