PURPOSE: An underground cofferdam or retaining pile and a cofferdam or retaining wall construction method thereby are provided to prevent collapse of earth and sand, and to insulate water by injecting cementer through the injection pipe after constructing the pile and by filling up the gap between the piles. CONSTITUTION: A cofferdam or retaining pile(100) is composed of a body(2) including a rod insertion hole(1) formed in the center, and an injection pipe(4) is longitudinally fixed and installed in the body. Plural injection holes(3) are formed in the injection pipe, and an installation groove(5) is recessed longitudinally in the outer periphery of the body. The injection pipe is inserted to the installation hole, and the injection holes are arranged outward. The injection pipe is not protruded out of the body, and the injection holes are exposed outward. Plural forms or bracket mounting nuts are installed in the body.
