PROBLEM TO BE SOLVED: To provide a construction method of a retaining wall structure which has a simple composition and in which a material cost is extremely low and a wall can be built by simple work in a short term, and also the effective utilization or the reuse of a steel reinforcing bar or the like can be made possible. SOLUTION: An axial pressure rod member 18 erected in front of the natural ground M is inserted to a cylindrical metal tube 20 of a required height and supported in a longitudinal direction, and tension is applied to the axial pressure rod by using the cylindrical metal tube as a base washer at the upper end side of the cylindrical metal tube, and a temporary support 14 having only the axial pressure rod member and the cylindrical metal tube which can be freely assembled or disassembled is formed. A wall body 16 is installed inside a temporary support, and is hardened by applying a hardening fluid inside the wall body and the first step of theretaining wall structure is completed. Thereafter, host temporary supports are connected to one another and extended by other axial pressure rod members and the cylindrical metal tubes at upper portions of the axial pressure rod members and the retaining wall is constructed up to the highest stage by sequentially applying and hardening the fluid inside the wall body, thereby installing the wall body.
