    摘要： There are provided methods of lining the internal surface of a pipe (7), which includes first inserting two lining pigs (3) into the pipe (7) and then introducing a batch of resin thereinto, or inserting one lining pig between two batches of a resin, or first inserting a lining pig and then inserting two batches of a resin with another lining pig therebetween, or first introducing a lining pig made of a soft material capable of deforming so as to pass through a narrow-passing section and then introducing a batch of a resin into the pipe, causing the resin to move forward until the front end of the resin reaches an inner end of the pipe (7), and sucking the resin back from the inner end so as to line the internal surface of the pipe with the resin. There are also provided improved liquid blocking pigs (6) for use in pipe lining treatment, each of such pigs (6) comprises a spherical body made of a soft resilient material and a least one flexible liquid barrier diaphragm interposed in the spherical body.

    摘要： There is provided a reversible lining tube 20 for repairing an existing pipelinel. Such a lining tube 20 is reversible into the existing pipeline 1 so that its initial inner surface 20b becomes outer surface 20a which adheres to the internal surface of the pipeline 1. In detail, the reversible lining tube includes an elastomer layer 20a and a flock layer 20b, prior to reversal into the existing pipeline 1 the elastomer layer 20a is an outer layer and the flock layer 20b is an inner layer, upon reversal into the existing pipeline 1 the elastomer layer becomes an inner layer and the flock layer becomes an outer layer which adheres to the internal surface of the existing pipeline 1. Alternative embodiments utilise a thread-knitted layer in place of the said flock layer.

    摘要： An amount of resin necessary for lining an inner surface of a pipe (2) is calculated. A lining pig (13) is inserted in the pipe from an open end thereof, and the calculated amount of resin is supplied in the pipe from the open end subsequent to the insertion of the lining pig. A blocking pig (14) is inserted in the pipe behind the resin, and a pressurized liquid is supplied in the pipe subsequent to the insertion of the blocking pig thereby feeding the charged resin through the blocking pig until a front end of the resin reaches an inner end of the pipe. The resin is sucked together with the lining pig and the blocking pig so that the inner surface of the pipe is lined with the resin.
