Claims (1)
- 本管と枝管からなる上水道管路をピグによって清掃する方法であって、本管は地中に埋設されており、枝管は地面から所定深さ掘った凹所内に突出し、一方の枝管から発泡密度0.02〜0.06g/cm3の軟質連泡体で、全面に軟質連泡体と同等の収縮性と可撓性があって、非圧力流体透過性の発泡樹脂からなる破泡ペーストを0.05〜0.8mmの厚さでコーティングし、全体がセル膜のない三次元網目状の繊維骨格を有する通過性、シール性、可撓性に優れたピグを挿入し、流体圧を受けて本管に進行し、ピグの持つ弾性回復力により管路内壁面に接触する大きさに瞬時に拡張してピグの外周面と管路内壁面が接触して堆積物を除去し、前記ピグを他方の枝管から取り出すことを特徴とする上水道管の清掃方法。
