PROBLEM TO BE SOLVED: To solve the problems that, for example, in a conventional ready mixed concrete leveling tool, when a worker does leveling work in ready mixed concrete placing, the worker has to move a handle part of the leveling tool in a vertical direction for adjusting, for adapting to a surface of the ready mixed concrete, because the leveling surface is a flat and square surface.SOLUTION: The leveling surface of the leveling tool is formed into a circular, a semi-circular or an elliptical shape, and is formed into a bar-state or a cylindrical structure. Thereby, a worker can do leveling work while adapting to the leveling surface without moving the handle in a vertical direction for adjusting. In addition, the leveling work can be done regardless of pushing and pulling, and the leveling work can be done smoothly, easily, and efficiently without irregularities of the ready mixed concrete surface. |
