<p>PROBLEM TO BE SOLVED: To carry out forcibly fusion joining and adhesive joining by preventing invasion of rain water, underground water, and the like. SOLUTION: A position where synthetic resin pipes 1 are connected to each other or the pipe 1 is repaired, is covered with a transparent or translucent cover body 3 so as to prevent invasion of rain water, underground water, and the like. Water drops stuck on the connecting part or a repair part of the synthetic resin pipe 1 are swept away by means of entering hand in the cover body 3, and then, a joint 2 is fused or adhesive joined on/with the connecting part or the repair part of the synthetic resin pipe 1. It is thus possible to prevent invasion of rain water, underground water, and the like so as to carry out piping simply and surely.</p> |
