PROBLEM TO BE SOLVED: To provide an execution method of a composite pile capable of being intruded after positioning a pile body smoothly in the ground in a highly accurate position and realizing reduction of execution time and the execution cost. SOLUTION: A pile body 20 is intruded in the ground 30, a hardness improver K is discharged from the discharge opening of the pile body 20 to create a composite pile 31 formed of the pile body 20 and the hardness improver K in the execution method of the composite pile. When intruding the pile body 20 in the ground 30, the hardness improver K is jetted out from the nozzles 23, 24 as the discharge opening provided in the pile body 20 to inject the hardness improver K into the ground 30 and intrude the pile body 20 to a specified depth of the ground 30 and inject the hardness improver K. Thereafter, the pile body 20 is left in the ground 30 as it is . In this way, the composite pile 31 formed of the pile body 20 and the hardness improver K is created. COPYRIGHT: (C)2005,JPO&NCIPI
