<p>PROBLEM TO BE SOLVED: To provide an appropriate propulsion pipe according to each of occasions for reducing the total thickness between a tunnel-like hole drilled by a boring machine and the propulsion pipe as much as possible in the case that the propulsion pipe is installed into the hole, and to enable a further increase in thickness of the propulsion pipe and the expansion of the installation area of the pipes when many propulsion pipes are consecutively installed to improve the durability of the pipes.SOLUTION: This invention relates to a propulsion pipe applied for a propulsion construction method, and the propulsion pipe is composed of a reinforced concrete pipe for a sewage work propulsion construction method having an inner diameter of 1100 mm, an outer diameter of 1536 mm, and a thickness of 218 mm.</p> |
