Ground leveling device for basement construction

The ground leveling device for basement construction comprises a supporting plate, a pushing handle is fixedly connected to one side of the supporting plate, supporting legs are fixedly connected to the four corners of the bottom of the supporting plate, a tamping assembly is arranged at the top of the supporting plate, and two movable rods are rotationally connected with a limiting plate. The bottom of the limiting plate is fixedly connected with a limiting block, and the limiting block is rotationally connected with a flattening roller. An output shaft of a second double-shaft motor drives a two-way screw to rotate, so that the two-way screw rotates to drive two moving blocks on the two-way screw to move mutually, movable rods fixed to the moving blocks are driven to move, and limiting plates rotationally connected to the movable rods move downwards along sliding grooves in supporting legs; and therefore, the flattening rollers rotationally connected between the limiting blocks on the limiting plates move d
