Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a curbstone backrest concrete construction device and a construction method. Background Art

[0002] Prefabricated curbstones are widely used in engineering projects. They are usually used to distinguish between carriageways, sidewalks, green spaces, isolation belts and other parts of roads, and serve as road water barriers.

The inner end of the push plate 21 is against the curb, and the outer end is flush with the side of the material storage bin 5. It is tilted from the inside to the outside, that is, the roadbed in front of the curb backrest 7 to be constructed is automatically scraped flat, and the surface loose soil, debris and garbage are removed to ensure that the backrest base is solid.

[0028] In implementation, see Figures 3 - 5 The process of using the above-mentioned construction device to construct the curb back concrete includes:

[0030] A concrete tank truck is used to continuously feed materials into the conical unloading hopper. During the feeding process, the curbstone backrest concrete construction device is slowly pushed forward. During the movement, the concrete slurry is gradually squeezed from the material storage bin into the space between the fixed trowel plate and the curbstone to initially form a backrest. At the same time, during the movement, the driving wheel rolls on the top surface of the curbstone and drives the roller to rotate through the horizontal bearing. During the rotation of the roller, the transmission connecting rod drives the movable trowel plate to move back and forth in the grooved track, thereby repeatedly smoothing the initially formed backrest to achieve a smooth surface.
