Abstract

PURPOSE:To easily connect pipes without inserting a robot into a pipe having a small diameter by judging the close contact state between a contact member and the outer peripheral surface of the pipe having the small diameter from the detection state of a contact detection part and adjusting the connection position of an installation pipe. CONSTITUTION:In the installation angle adjustment for a guide pipe 13, it is detected and confirmed that the contact part 10 on the equal curved surface to the outer peripheral surface of a pipe 1 having a small diameter closely contacts said pipe 1 and the pipe 13 is at a prescribed angle position for the pipe 1, from the stop of the injection of fluid supplied from all the injection holes 11. Then, a drilling device 15 is lowered along the inner peripheral surface of the pipe 13, and the pipe 13 is set at the center, and a pipe connecting hole 17 is drilled onto the pipe 1. The drilling device 15 is pulled up from the pipe 13 and an installation pipe 18 is lowered along the inner peripheral surface of the pipe 13, and a cylindrical connecting member 20 which is fitted onto the edge part and possesses elasticity is press-fitted onto the pipe connecting hole 17 on the pipe 1. Then, an outside casing 4 and the guide pipe 13 are removed, and the pipe 1 and a contaminated water reservoir or rainwater reservoir 21 are connected by the installation pipe 18 through the connecting member 20.
