A steel bridge deck pavement equipment

Abstract

The invention discloses a steel bridge deck pavement equipment, which relates to the technical field of infrastructure for bridge engineering, including a frame, a base, a cleaning mechanism and a filling mechanism, an air injection device is installed on the upper end of the frame, and the The jet device is connected with a vortex tube through an air intake pipe, and a chamber 1 and a chamber 2 are opened inside the base. In the present invention, a cleaning mechanism is set in the base, and several shells are rotated in the crack, so as to stir and knock off the stubborn attachments on the inner wall of the crack, and blow them out by high-speed airflow. At the same time, the shells first shrink and then increase. The large deformation process ensures that the cracks can be completely cleaned, thereby improving the pavement repair effect of the cracks; by setting the filling mechanism, the excess sealing glue is scraped off by the scraper under the drive of the drive motor and smoothed, no need Manually pour and install and disassemble the pre-embedded glue nozzle, paving and repairing quickly and in a large area.

Description

Technical field [0001] The present invention relates to the field of infrastructure technology for bridge engineering, and more particularly to a steel bridge bridge paving device. Background technique [0002] The steel bridge bridge pavement mainly uses two structural methods, including double-layer SMA structures and epoxy asphalt concrete structures, but no matter what paving method, time has long been inevitable, cracks, in order to repair and block cracks Continuing to expand, the prior art is usually paved in the way, and the specific operation is: manual operation is cut out along the cracked V-groove or directly sand blast, and use a high pressure air pump to blow out the internal dust, and then embedded Narrow mouth and apply a sealing gum, then directly perfuse the sewing after test leak detection, and after the finish is filled with the bridge base surface and polished. [0003] In the course of the bridge scholarship repair of the bridge, our company found that there...

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
