<P>PROBLEM TO BE SOLVED: To provide an impermeable wall construction method, capable of constructing an impermeable wall without using a special device or boring machine and without unnecessary increase in strength. Ž<P>SOLUTION: A ground excavating jet flow (12J) is injected downwardly from the lower end of a steel product (10 or 20), while the steel product (10 or 20) is pushed into a ground (G) that is a construction object while giving vibration or impact thereto. When the steel product (10 or 20) is pushed to a predetermined depth (D), a solidification material jet flow (jet 14J) is injected from a solidification material injection nozzle (14) provided at the lower end of the steel product (10 or 20) in a horizontal direction (L) while pulling up the steel product (10 or 20) toward a ground side (U).
