PROBLEM TO BE SOLVED: To dissolve the problem that mixing takes time and increases cost. SOLUTION: A mixing apparatus 10 mixes coal ash pellets provided on the seabed with submarine earth and sand. The mixing apparatus 10 is equipped with a frame 11, four legs 14, a front gliding plate 13 and a back gliding plate 15. Respective legs 14 are connected with the frame 11 to arrange the frame 11 above a surface of a layer containing the coal ash pellets and in a plane which is about parallel with the surface. The frame 11 moves in the plane. Inside the frame, three attaching members 23 stretch about vertically to a moving direction and are provided with intervals in the moving direction. At each attaching member 23, groove forming members 31 stretch more downward than the front gliding plate 13 and the back gliding plate 15 from mutually different positions of the attaching members 23 in a longitudinal direction.
