PROBLEM TO BE SOLVED: To provide a concrete L type pile capable of shortening a long construction period of time at a low cost since a retaining wall method and a wooden pile method for earth retaining are branch work in a landslide construction site. SOLUTION: A fall of a concrete pile can be prevented by making the concrete pile as an L-shape to enable it to resist tensile load by a cross and uneven shape. Mass production of the concrete L-type pile can be made at a low cost by plant manufacture. A construction period of time can be reduced in the construction site, and design dimensions can be changed in accordance with the site. It is also applicable to emergency repair work.
