PROBLEM TO BE SOLVED: To construct a continuous wall, a foundation pile and like not only by substituting an inexpensive concrete pile for a relatively expensive steel pipe sheet pile but also by using a conventionally existing small-bore concrete pile. SOLUTION: Joint mounting members 12, which are formed like a ring of a diameter almost equal to that of a pile body 10, are prewelded at every required interval in the longitudinal direction of the pile body 10. After the placing of concrete, the members 12 are exposingly formed in required positions on the peripheral surface of the pile body 10 so as to be integral with the pile body 10. Furthermore, a plurality of joints 13 and 13 are fixed to the surfaces of the members 12 in the longitudinal direction of the pile body 10, so that a concrete-pile sheet pile 100 can be formed.
