Description

Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to a prefabricated small box beam with a water discharge function. Background Art

[0002] The small box girder is a commonly used structural form in bridge engineering. It is mainly composed of a beam top plate, a beam web plate and a beam bottom plate. It has good bearing capacity and rigidity and is often used in projects such as small and medium span bridges.

[0003] Because the small box girder has been used for too long, its structure will be corroded, causing water to accumulate in the box, resulting in increased load, accelerated corrosion, and increased safety hazards.

[0004] Therefore, it is necessary to propose a prefabricated small box girder with a water drainage function to prevent the increase in load and accelerated corrosion caused by water accumulation in the box girder, thereby reducing safety hazards and reducing project risks. Utility Model Content

[0005] The utility model provides a prefabricated small box beam with a water drainage function, which prevents the load increase and corrosion acceleration caused by water accumulation in the box beam, thereby reducing safety hazards and lowering project risks.

[0006] The purpose of the utility model is achieved through the following technical scheme: a prefabricated small box beam with a drainage function, comprising a box body, the interior of the box body is hollow, the bottom wall of the box body is provided with at least one drainage hole, the upper arms at both ends of the box body are provided with end concrete pouring holes, and the two ends of the box body are provided with plugging plates matching the interior thereof, and the drainage hole and the end concrete pouring hole are respectively located on both sides of the plugging plate.

[0007] Concrete plugs are arranged at both ends of the box body.

[0008] The left and right ends of the box body are provided with drip grooves.

[0009] Wing plate wet joints are arranged on both sides of the box body.

[0010] Both ends of the box body are provided with quick closing nets.

[0011] Both sides of the two ends of the box body are provided with horizontal partition wet joints.

[0012] The beneficial effect of the utility model is that by setting the drain hole, when water enters the box body, the accumulated water can be discharged from the drain hole, preventing the load increase and accelerated corrosion caused by water accumulation in the box beam, thereby reducing safety hazards and lowering project risks.
