PROBLEM TO BE SOLVED: To prevent the lift of a core material, and to prevent the core material from being deviated from an axis line due to the lift even if a soil column is formed by using the core material such as wood.SOLUTION: This core material inserting implement 1 includes: a base 21 which is installed on a ground surface outside a drilled hole 61 when solidification agent slurry 62 is injected into the drilled hole 61 and the core material 51 formed of wood is inserted into the solidification agent slurry 62; an inner wall 31 which is formed inside the base 21, and in which the core material 51 inserted into the solidification agent slurry 62 can be inserted; and an insertion portion 32 which is provided at the inner wall 31 and into which a protrusion formed at the lateral surface of the core material 51 can be inserted. After the protrusion 52 of the core material 51 is inserted via the insertion portion 32, the protrusion 52 abuts on the lower portion of the inner wall by turning the core material 51 in an axial direction. |
