By setting a spirit level, the offset situation shown by the spirit level shows the flatness situation at that place. The spirit level does not need to contact the concrete surface, will not be worn, and will not have a problem of large error caused by its own wear, and does not affect the staff's judgment of the flatness of the concrete surface.
