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.
摘要翻译：一种将刚性塑料衬管插入导管中的方法，其中将塑料管从滚筒中拉出时将围绕滚筒缠绕的扁平折叠状态的刚性塑料管插入导管中，包括以下步骤：加热的流体从导管的一个端部开口流到另一端，并且加热流体流过导管的加热流体加热塑料管的整个内圆周表面，使软管变软。根据本发明，塑料管可以在其整个长度上均匀地被软化，塑料管保持在卷绕状态，并且即使在管插入时也可以将其保持在热软化状态导管。可以高效率地将刚性塑料管插入导管中。此外，即使当导管在其中间部分具有弯曲部分时，塑料管可以容易地穿过弯曲部分而插入其中。

摘要： A method for repairing a buried pipe by a new metal pipe that is inserted into the buried pipe comprising the steps of carrying to an installation site flat collapsed metal pipe material taken up into a roll that is processed to be deformed into a flat collapsed state in which the effective outside diameter is reduced and that can be restored by expansion to have an outside diameter that corresponds to an inside diameter of the buried pipe by virtue of an inner pressure, setting the rolled metal pipe material on the ground, then feeding out the pipe material form the taken up roll so as to insert it into the buried pipe through a working pit formed under the ground, thereafter sealing the pipe material so inserted at both ends thereof, and pressurising the pipe material from the interior thereof by virtue of pressurising fluid so as to be restored by expansion to the metal pipe having its restored circular cross section, whereby the metal pipe can be laid inside the buried pipe with good working efficiency and without providing a large-scale working space inside the working pit.

摘要： A joiner for joining wound side edges of a liner strip wound helically along the inner surface of a pipe, which joiner includes a longitudinally elongated main body and a pair of engagement protuberance portions disposed on the outer surface side of both side portions of the main body portion in such a manner as to extend in a longitudinal direction and to protrude outward. A bending deforming portion so deformed as to be capable of bending in a transverse direction is formed at the center of the main body connecting the both side portions, and this bending deforming portion bends or stretches to accommodate a gap or a step defined between the wound side edges of the liner strip by its bending operation.

摘要： Duct lining method, in which a hard plastic tube inserted into a duct is thermally pressed from the inner side thereof so as to expand the tube and form a lining, consists of the steps of retaining the shape of the plastic tube, which has been expanded by an electrically heated tube expanding pigtail moving therein, by supplying compressed air into the expanded tube; and preheating an unexpanded part of the plastic tube by utilizing a part of the compressed air heated as it passes through an air heating passage in the pigtail. Owing to the use of the electrically heated tube expanding pigtail, the limitation placed on the material for the plastic tube and the softening point thereof can be removed. Owing to the preheating of the unexpanded part of the plastic tube, a speed at which the tube expanding pigtail moves in the duct can be increased, so that an operation efficiency can be improved.

摘要： A method of lining a channel can be provided which includes the steps of: installing at a work site a roll having wound thereon a rigid or semirigid plastic pipe shaped initially in the form of an approximately round tube and deformed from the initial form to a flat tubular form, paying off the pipe as softened by heating from the roll installed at the work site toward an inlet of the channel to be lined, and folding the paid-off flat pipe in two to a U shape at a position between the roll and the channel inlet. The U-shaped pipe is hardened by forced cooling from outside immediately after the folding step while being restricted in shape, then inserted into the channel while being thus hardened and thereafter restored to the initial form by being inflated with heat and pressure applied from inside, whereby a lining of improved quality can be formed with an improved work efficiency.
