<p>PROBLEM TO BE SOLVED: To certainly bury a piping even though work to dig the ground over is not performed precisely when the piping in which wiring such as electric wires is stored is embedded in the ground, by inclining the upper surface of the contact part to the bottom surface of the pedestal in a jig comprising a pedestal and a contact part arranged on the pedestal. SOLUTION: A correcting jig 1 broadly comprises a pedestal 2 and a contact part 3. The pedestal 2 is a part brought into contact with the ground when the correcting jig 1 is placed on the ground, therefore the pedestal 2 is required to have a stable shape so that the correcting jig 1 may not be inclined even though a piping and U-shaped groove are placed on the upper part. The shape of the contact part 3 is not especially limited so long as an upper surface 31 is inclined to the bottom surface 21 of the pedestal 2, and is preferably formed into a shape that a triangle column is transversely brought down. The contact part 3 may be formed of one part, and also may be separated into two parts. If the contact part 3 formed of one part and width W are the same, similar stability can be obtained, and the jig 1 can be manufactured from a small amount of raw materials.</p> |
