The present invention relates to a pile for constructing a retaining wall on a flimsy ground, including a cut area caused by mountain cutting, and a method for constructing a retaining wall using the same, wherein a flimsy ground, including a cut area caused by mountain cutting, is reinforced using a longitudinal pile, and the construction is made easier compared with existing methods, thereby saving human and material resources. A boring groove (70) is formed on a cut area, which is caused by mountain cutting, and a flimsy ground, which is susceptible to ground subsidence, such that at least one pile (S) can be inserted and fixed therein, a pile (S) is then inserted into the boring groove (70), and a finish block is integrally constructed on an end of the pile, the pile comprising: an inner pipe (10) having attachment means (11) configured on wall surfaces of inner and outer diameters thereof using one selected from wrinkles and corrugations such that a strong force of attachment with a filler (50) can be exhibited, the inner pipe (10) having a predetermined length; an outer pipe (20) arranged to face outwards from the center of the inner pipe (10) while having the same length as that of the inner pipe (10), the outer pipe (20) having attachment means (21) configured on the inner wall surface thereof using one selected from wrinkles and corrugations such that a strong force of attachment with the filler (50) can be exhibited, and the outer pipe (20) having cohesion means (22) configured on the outer wall surface thereof using one selected from wrinkles and corrugations such that a strong force of cohesion with the ground can be exhibited inside the boring groove (70); a support pipe (40) configured such that the inner pipe (10) and the outer pipe (20) are arranged and fixed at a predetermined interval, thereby forming a receiving space (30), and the filler (50), which fills the inner pipe (10), diverges outwards, thereby improving the force of cohesion with soil inside the boring groove (70); a filler (50) in a slush state, which forcibly fills the receiving space (30); and a support body (60) buried inside the filler (50) so as to improve the force of attachment, the support body (60) having an extension (61) having an extended length compared with the inner and outer pipes (10, 20). |
