置。 A running beam that straddles between rails laid on both sides of a concrete pouring surface and can run freely on the rails, and a running body that is movable on the running beam in a direction perpendicular to the running direction of the running beam. A concrete leveling section is provided on this running body via a vertical adjustment mechanism and a leveling mechanism, and this concrete leveling section is provided with a running distance detector for detecting a relative movement distance with respect to the running beam, and an inclination angle. A detector and a laser receiver that is movable up and down relative to the leveling section and receives a laser beam emitted at a predetermined height are provided, and the distance of the concrete leveling section detected by the traveling distance detector is provided. A receiver control device that calculates the amount of vertical movement of the laser receiver based on the amount of movement and a preset gradient value, and operates a vertical movement mechanism that moves the laser receiver up and down the required amount based on the calculated value. At the same time, the values of the height and slope angle of the leveled concrete portion detected by the laser receiver and the slope angle detector are compared with preset values, and the vertical adjustment is performed based on the calculation results. A concrete leveling device comprising a leveling unit control device that operates a mechanism and a level adjustment mechanism so that a laser receiver is always positioned at a constant height.
