<p>PROBLEM TO BE SOLVED: To efficiently conduct the exchanging works of a water service pipe or the like buried in a ground. SOLUTION: A wire 64 in which one end section is connected to the connector 10 is passed into the water service pipe 51 from the end section 51a (one end section) of the water service pipe 51 buried in the ground, and the other end section of the wire 64 is exposed outside the end section 51b (the other end section) of the water service pipe 51. One end section 56a of another water service pipe 56 is connected at the end section 51a of the water service pipe 51 through the connector 10. The connector 10 is pulled by pulling the other end section of the wire 64 exposed outside the end section 51b of the water service pipe 51, and the water service pipe 51 from the end section 51a to the end section 51b is extracted from an underground section by the connector 10 while another water service pipe 56 is buried into the ground.</p> |
