PROBLEM TO BE SOLVED: To provide an improved soil pouring device which downward transfers flowable improved soil obtained by kneading earth and a hardener added thereto through a transfer pipe from a pouring ship to the sea bottom, wherein separation of earth in the improved soil can be effectively suppressed before the improved soil lowering through the interior of the transfer pipe reaches the sea bottom. SOLUTION: The transfer pipe 12 has an inverted flow passage 21 formed therein, which inverts the improved soil S having lowered through the interior of the pipe, at a location in the vicinity of an outlet port 12o of the pipe 12 and allows the improved soil S to upward flow by a predetermined height. Thus, the improved soil is discharged from the outlet port 12o of the transfer pipe 12 via the inverted flow passage 21.
