POLISHING DEVICE FOR POLISHING PIPE INNER SURFACE OF EXISTING DRAIN PIPE AND WATER LEAKAGE REPAIR METHOD OF EXISTING DRAIN PIPE
To provide a polishing device for polishing a pipe inner surface of an existing cut drain pipe with good workability, and to provide a water leakage repair method which enables water leakage from a slab penetration part of the existing drain pipe to be easily repaired.SOLUTION: A polishing device including a tubular shaft which is inserted into an existing cut drain pipe from the tip side, polishes its inner surface, and suctions and recovers dust generated due to polishing is used. Further, a method for repairing water leakage of the existing drain pipe, penetrating through a slab, from a slab penetration part with an airbag is used.SELECTED DRAWING: Figure 1
【課題】切断された既設配水管の管内面を作業性良く研磨するための研磨装置を提供する、また、既設配水管のスラブ貫通部からの漏水を容易に補修することができる漏水補修方法を提供する。【解決手段】切断された既設排水管に先端側から挿入してその内面を研磨し、研磨で発生した塵芥を吸引して回収する管状シャフトを備える研磨装置を用いる。また、スラブを貫通する既設排水管の、スラブ貫通部からの漏水をエアバッグを用いて補修する方法を用いる。【選択図】図１
