ASEISMIC PROPULSION PIPE JOINT

摘要

PROBLEM TO BE SOLVED: To prevent the increase of the resistance in propulsion on the basis of the flow of sediment in laying an aseismic pipe in the ground by a propulsion method. SOLUTION: A spigot 14 formed on an end of one of armor pipes 13 for propulsion method is inserted inside of a socket 12 formed on an end of armor pipe 12 to be joined to the pipe 13, and the pipe moving force can be conducted between the socket 12 and the spigot 14 in laying a conduit line. An aseismic structure having a separation preventing function and an expanding and contracting function exists between the socket 12 and the spigot 14. A projecting part 24 is formed on an outer face of the spigot 14 at the outside of the socket 12, and a pressing force conducting member 26 is mounted between the projecting part 24 and an end part of the socket 12. A cover for preventing the inflow of sediment 35 is wound from the outer periphery of an armoring part 31 of the pipe 13 at the spigot side to the outer periphery of the socket 12. The cover 35 is connected to the pressing force conducting member 26.
