Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a seam filling auxiliary mechanism for bridge construction. Background Art

[0002] A bridge refers to a building built for roads to cross natural or artificial obstacles. It is erected across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. During the bridge construction process, grouting technology is an important link to ensure the flatness, waterproofness and anti-seepage of the bridge deck, which directly affects the service life of the bridge and driving safety.

[0003] The existing utility model with authorization announcement number CN218466289U discloses a grouting auxiliary equipment for bridge construction, including a base, a support block is provided on one side of the upper surface of the base, and two push rods are provided on one side of the top of the support block, and the two push rods are symmetrically placed in parallel; a plurality of universal wheels are provided on the lower surface of the base, and each of the universal wheels is rotatably connected to the base through a bearing; a pressurizing mechanism is provided on the end of the base away from the support block and passes through the interior of the base; a grouting mechanism is connected to the side of the upper end of the support block away from the push rod, one end of the grouting mechanism is connected to the support block, and the other end can be sleeved with the pressurizing mechanism.

[0004] The above technical solution is adopted by setting a seam pressing mechanism, so that the base moves to drive the support column to move, and the seam pressing rod drives the seam pressing ball to press the asphalt or sealant used to fill the cut seam, so that the asphalt or sealant can be better filled with the inside of the cut seam. However, the above technical solution is not convenient for cleaning the inside of the gap when grouting the bridge, so that the dust or impurities inside the gap not only affect the bonding effect of the grouting material, but also shorten the life of the sealing system, resulting in poor bridge reinforcement effect. In addition, it is inconvenient to scrape the grouting material after grouting, so that the grouting material is easy to be higher than the bridge gap, affecting the aesthetics of the road surface, and thus has low practicality.

[0005] Therefore, those skilled in the art provide a grouting auxiliary mechanism for bridge construction to solve the problems raised in the above background technology. Utility Model Content
