PROBLEM TO BE SOLVED: To provide a correction confirming apparatus capable of confirming an inclination correction applied to an upper core material element added to a lower core material element which is embedded first, in particular, to a lower core material element embedded in the ground.SOLUTION: An inclination correction confirming apparatus comprises: a bottomed pipe member mounted to a core material element positioning lowest and extending in an axial line direction of the core material element; a light source disposed on the bottom of the pipe member; a pipe member which is mounted to all other core material elements than the lowest positioning core material element and extends in the axial line direction of each core material element and in which, when adding an upper core material element to a lower core material element, pipe members of both the core material elements are matched with each other; an imaging apparatus which is supported by the upper core material element and faces an upper end opening of the pipe member of the upper core material element; and a monitor electrically connected to the imaging apparatus for projecting a video image captured by the imaging apparatus. |
