Description

Technical Field

[0001] The utility model relates to the technical field of concrete pavement leveling equipment, in particular to a concrete leveling machine. Background Art

[0002] Concrete pavement refers to a pavement with cement concrete slab as the surface layer. It refers to a pavement structure composed of cement concrete slab as the surface layer, with base layer and cushion layer as the bottom layer, also known as rigid pavement. During construction, the mixture transported to the pouring site is generally poured directly into the road groove with the side form installed, and is evenly filled by manual work. When paving, a large iron palladium is used to disperse the mixture, and then a shovel and scraper are used to disperse and flatten the material. Near the formwork, a square shovel is needed to spread the mixture and tamp it several times to make the mortar tamp out to avoid the occurrence of hollow honeycomb phenomenon. However, traditional concrete leveling requires vibration with a flat vibrator. In order to make the concrete surface more flat and dense, an iron roller is needed to further level it, which increases the operation steps, which requires a lot of manual operation and increases labor costs. At the same time, the roller lacks pressure on the concrete. When encountering protruding stones, the roller will jump, resulting in uneven concrete pavement, which requires manual repair later, which is time-consuming and labor-intensive and reduces work efficiency.
