A cold-setting synthetic resin liquid is poured into these molds. The injected synthetic resin liquid hardens to become a flexible synthetic resin filler, fills the gaps between the connecting pipes 12 and covers the outer circumference of the connecting pipe 12 group, and flexibly integrates the entire connecting portion. Room temperature curing type synthetic resin liquid is a liquid with relatively low viscosity at the time of injection, such as a two-component polyurethane resin or silicone resin. After injection, the reaction proceeds at room temperature and cures in a relatively short time. Those that produce a flexible synthetic resin are preferably used.
