DRAINING METHOD IN CYLINDRICAL LINING MATERIAL IN CONDUIT

摘要

PROBLEM TO BE SOLVED: To provide a draining method in a cylindrical lining material in a conduit capable of certainly and efficiently discharging drain with a simple method even if the drain stays at any position or a plurality of positions without previously specifying a drain staying position in the cylindrical lining material.

SOLUTION: A wire rope 4 is passed through the cylindrical lining material 3 inserted into a conduit 1 and is led out to the outside of the cylindrical lining material 3 such that both ends are reciprocated by tension. A tip end is hung down at a position in the cylindrical lining material 3 of the wire rope 4 and a neighborhood to the tip end of a flexible drain removal tube 3 is fixed such that it is slide-contacted with an inner bottom part of the cylindrical lining material 3. The wire rope 4 is reciprocated in the whole length direction of the cylindrical lining material 3 to discharge the drain D staying in the cylindrical lining material 3.
