Zusammenfassung: | PURPOSE:To provide a tunnel support pole for crop raising suitable for planting working underground using a tunnel support pole working machine. CONSTITUTION:A support pole body 1 with circular section is bent in an arch- shaped manner and the central part of the body 1 is deformed flat in the form of e.g. ellipsoid with longitudinally longer section to form a deformed central part 11. This deformed central part 11 is engaged with a support pole-aligning packer 2 with groove-shaped section. Owing to the above scheme, when the support pole body 1 is to be alignedly set on a tunnel support pole working machine, the packer 2 does not slip or rotate even if external force is applied on the packer 2, being able to be held at a specified position, and the support pole body 1 is easily alignedly set with the packer 2 arranged in parallel with the guide for the working machine. |
