PROBLEM TO BE SOLVED: To effectively make use of concrete muck as industrial wastes. SOLUTION: A steel pipe concrete pile 1 is filled with concrete much 16 as industrial wastes in a steel pipe 11 installed to reach a bearing stratum 3. Further, mortar 17 is pressed-in to immerse the concrete muck into the mortar and shut the muck in the whole body of the steel pipe. In the execution method, the front end of the steel pipe is sealed with water sealing concrete 13 and a tremie pipe 14 is inserted in the steel pipe and concrete muck is filled into the steel pipe and then, mortar is pressed-in the pipe through the tremie pipe to immerse concrete muck into the mortar. The filling process of concrete muck into the steel pipe and the pressing-in process of mortar are repeatedly carried out by every specified distance in the height direction of the steel pipe.
