Description

Technical Field

[0001] The utility model relates to the technical field of cement paving, in particular to a handheld cement paving device. Background Art

[0002] Cement paving is a construction method that refers to laying concrete evenly in a predetermined area at one time, and using professional tools to vibrate and compact it to ensure that the concrete can tightly fill every inch of the ground until the entire cement surface is completely paved. This method is particularly suitable for road construction with a relatively small area and narrow width, such as roads, sidewalks or other small venues in a community. Since this method can complete most of the paving work at one time, it has significant advantages in efficiency and quality, and is deeply favored by construction workers.

[0003] During the cement paving process on the residential pavement, workers need to hold a rotating roller to squeeze and compact the newly laid cement pavement. This step is crucial because it ensures that the concrete is tightly filled to prevent gaps and unevenness. Then, after the extrusion and compaction are completed, the workers need to use a trowel to carefully smooth the compacted cement pavement to achieve a mirror-like smoothness. This series of processes is relatively cumbersome and requires not only close cooperation from the workers, but also manual control of tools for precise operation, which undoubtedly increases labor consumption and reduces the overall efficiency of cement paving. Therefore, seeking more efficient and automated paving methods has become an urgent need to improve construction efficiency and quality.

[0004] Therefore, it is necessary to provide a new handheld cement paving device to solve the above technical problems. Utility Model Content
