摘要

PROBLEM TO BE SOLVED: To provide simple structure making executability excellent and eliminating the possibility of a body pipe that constitutes a buried pipeline, entering a handhole. SOLUTION: In this connection structure, a cylindrical connecting member 30 is fitted to a side wall 11 of a handhole 10 with mortar 12 so as to pierce the side wall 11, and a body pipe 21 constituting a buried pipeline 20 is inserted in the connecting member 30 and jointed. A plurality of shield tubes 41 are inserted through the body pipe 21. The end of the connecting member 30 is provided with a flange part 32 protruded inward so that the end face of the body pipe 21 inserted in the connecting member 30 butts against the flange part 32.
