<p>PURPOSE:To implement a method of burying a pipe capable of reducing the work period by adopting a method of reinforcing the circumference of the pipe in which no transverse hole other than the transverse hole for burying the pipe is necessary. CONSTITUTION:In a condition that an inner pipe 14 is inserted into an outer pipe 11 having a plurality of through-hole parts 12 in the sidewall, the outer pipe 11 and inner pipe 14 are buried in the ground G. In this condition, while the gap 15 between the pipes 11, 14 is filled with concrete 20, the concrete 20 is set in a condition that a part of the concrete 20 flows to the outside via the through-hole parts 12 in the outer pipe 11.</p> |
