Inner surface lining method of a tube

Abstract

Abstract PURPOSE: The lining tube is inverted, the liquid is inserted into the tube by the fluid pressure. To line with good workability on the inner surface of the tube by coating adhesives on the inner surface of the tube and by sticking the tube. CONSTITUTION: The shafts 3 and 4 are sunk in the ground, the wire 6 is fixed to the top 5a of the charging material 5, the charging material 5 is inserted in the exposed lining tube 2. The inlet cylinder 8 which opens upwardly is fixed in the end of the tube 2 of the shaft 3, and the adhesives 10 is poured into the cylinder. After that, the lining tube 12 made of the flexible synthetic resin is inserted from the inlet cylinder 8, the end of the tube 12 is fixed on all over the upper of the cylinder 8, the outer surface of the tube 12 is changed to the external side in the cylinder 8 and tube 12, the inversion part 12a is formed. Next, the pressured fluid is introduced in the inversion part 12a from the side of the shaft 3 to the direction of arrowhead 13, the pressured fluid is pushed over changing the inner surface of the tube 2 along with the inner surface of the tube 12, the adhesives 10 is coated on the inner surface of the tube 2, at the same time, the tube 12 is attached to the inner surface of the tube 2.
