摘要

A stair type retaining wall and a construction method of a stair type retaining wall using the same are provided to make the installation work facilitated and the support of the retaining wall body structurally stabilized. A construction method of a stair type retaining wall comprises the followings. A tensile member(14) of the soil nail is connected through an anchor plate(12) to an engage nut(12a). A liner screw(14a) is formed on the tensile member of the soil nail. An enclosed type annular part of the circular shape or the elliptic shape connects to a wire(30) fixed to the enclosed type annular part.
