摘要： A method of lining the inner surface of a conduit, comprising placing on the site a roll of hard or semi-hard plastic pipe deformed from the original shape, i.e. a generally circular pipe to a flat pipe drawing out the thermally softened pipe from the roll toward the opening of a conduit to be lined therewith, folding in two to a shape like the letter U in front of the opening, wherein the U-folded pipe is immediately set fixedly by cooling it forcedly from the outer surface of the pipe whose shape is kept retained, put into the conduit in this shape-retained state, restored to its original shape by expanding the pipe by heat and pressure from the inner side thereof. The lining is facilitated, and the quality of lining is improved.

摘要： A method of lining a pipe (a) with a rigid to semirigid plastic tube (1) inserted through the pipe by inflating the tube by application of heat and pressure, the method being characterized in that the tube has a large wall thickness and is formed with a multiplicity of bores (1a) extending through the tube wall axially thereof and arranged in parallel at a spacing circumferentially of the tube, the tube being heated by passing a heating fluid through the bores. The tube having the large wall thickness can be uniformly heated throughout the entire wall thickness so as to be inflated fully by the application of pressure free of the likelihood of insufficient inflation or rupture and to line the pipe.

摘要： A method of inserting a rigid plastic lining tube into a conduit wherein a rigid plastic tube wound in a flatly folded state around a drum is inserted into a conduit as the plastic tube is pulled out of the drum, comprises the steps of supplying a heated fluid into the conduit so that the heated fluid flows from one end opening of the conduit to the other, and heating the whole of the inner circumferential surface of the plastic tube with this heating fluid flowing through the conduit, to soften the same tube. According to the present invention, the plastic tube can be softened with heat uniformly along the whole length thereof with the plastic tube kept in a drum-wound state, and it can also be maintained in a thermally softened state even while the tube is inserted into the conduit. The insertion of the rigid plastic tube into the conduit can be carried out with a high efficiency. Moreover, even when the conduit has a bent portion at an intermediate part thereof, the plastic tube can be inserted thereinto as it is passed through the bent portion easily.

摘要： A method of forming a rigid or semirigid plastics tube lining over the inner surface of a branch pipe portion as joined at its one end to an underground main pipe through the other end thereof substantially open to the surface of the ground as a work opening, the method being characterized by inserting a rigid or semirigid plastics tube into the branch pipe portion from the work opening with the forward end of the tube substantially closed, and subsequently supplying a fluid into the tube to inflate the tube radially of the branch pipe by applying heat and pressure to the tube with the fluid from inside directly or indirectly and thereby line the branch pipe portion with the rigid plastics tube. The pipe portion can be lined from the ground surface efficiently without necessitating labor for excavation of the ground, cutting off the branch pipe portion and restoring the piping to the original state.

摘要： An apparatus or pig easily movable inside pipes for cutting off projections eg liner portions in the interior of the pipe along the inner surface of the pipe. The apparatus includes a carrier movable inside the pipe. The carrier is provided with a shaft 7 reciprocatingly movable axially of the pipe and rockingly rotatable circumferentially of the pipe, a rocking block 9 movable with the shaft 7 and a drive device for the shaft. The rocking block 9 has a cutter blade 10 reciprocatingly movable axially and radially of the pipe as projected forward from the block 9 axially of the pipe, and drive devices for the blade 10.
