ABSTRACT:
The present invention relates to an improvement in a lining method for internal surfaces of pipes in multi-branched pipings such as water pipes, gas pipes, etc. in which a plurality of branched pipelines are branched from a main pipeline, and particularly to a shaping method for a lining surface.
In a multi-branched piping in which a plurality of branched pipelines are branched from a main pipeline, a coating is poured into a pipeline from one end of a main pipeline or each of the branched pipelines, gas is then fed to thereby line the internal surface of the pipeline, a sponge consisting of an elastic foam body having a larger diameter than the inside diameter of the pipe constituting the pipeline, said foam body being made of synthetic resin and having a continuous foam, is inserted from an end of each branched pipeline, and the sponge is then pushed with the aid of air pressure whereby the lining surface can be shaped to have substantially uniform film thickness.
