<p>The present invention relates to a shaft construction method of vertically building a plurality of pipes (10), including the steps of: setting a position for disposing a lower pipe (10a) among the pipes (10) on the surface of the ground (1) at which an upper opening part of the shaft is positioned; sinking the lower pipe (10a) by excavating the lower ground (1a) via the inside of the lower pipe (10a); and connecting an intermediate pipe (10b) among the pipes (10) to the upper end of the lower pipe (10a), wherein the pipes (10) are buried in the ground (1) and a hollow is formed inside the pipes (10) by repeating the excavating and connecting steps, and safe and simple construction of a shaft is realized at low cost in reduced construction time regardless of the state of the ground.</p> |
