A constructing method of top-down type retaining wall for vertical cut slope, using a partially buried H-pile, is provided to construct a retaining wall for vertical cut slope at low cost without installation of temporary structure. A constructing method of top-down type retaining wall for vertical cut slope comprises a step of setting up an H-pile(20) in the ground so that only a part of the H-pile is buried in a filler, a step of excavating the ground in front of the H-pile so that the rest part of the H-pile is exposed, a step of setting up a concrete wall(40) by applying concrete between the exposed portion of the H-pile and the front side of the ground, and a step of forming a retaining wall by stacking retaining wall blocks(70) successively, wherein the retaining wall block is composed of a pile block(71) positioned in front of the H-pile and a middle block(72) positioned between the pile blocks. |
