PROBLEM TO BE SOLVED: To provide the underground burying method of a sheet pile, by which a work area in the case of sheet-pile burying can be greatly reduced while burying by a small-sized crane car is enabled by lightening the press-in force of the sheet pile and an effect on an adjacent building or the like is also prevented, and the sheet pile used for the method. SOLUTION: Auger screws 3 are arranged into the recessed spaces 43 of the sheet piles 4 formed in a recessed cross section curved in an arcuate shape and droopingly provided on a ground surface, and the sheet piles 4 are pressed in and buried into a ground with penetration into the ground of the auger screws 3. The sheet piles 4 are connected by connecting sections 44, 45 formed at mutual side edges by directing the recessed spaces 43 towards the same sides, and successively pressed into the ground and buried in a row.
