悪いものであった。On the other hand, in recent years, resin pipes such as polyethylene pipes and polybutene pipes, which do not cause water leakage accidents due to corrosion and red water, have come to be frequently used for water supply and hot water supply pipes. The pipe construction method using such a resin pipe is a method of inserting the resin pipe after the pipe such as a corrugated pipe (hereinafter referred to as an existing pipe) is preliminarily constructed. There is sufficient clearance between the pipes. Therefore, when water or hot water is used, the piping vibrates due to the water pressure, and impact noise or vibration noise is generated, which causes a problem of noise pollution. In order to prevent this, a method of putting a foamed plastic sheet into a gap is adopted, but the mechanical strength such as tensile strength and tear strength is weak, and it breaks during construction and is cut, resulting in poor workability.
