    摘要： This invention concerns a method and apparatus for repairing drains and underground pipelines, which comprises drawing a tubular ejector body (20) to a position such that the leading end and the trailing end of said body are disposed to one side and the other side of the defect, after there sealing rings (38) are infloted around the body (20) at or near the leading and trailing end, supplying a multicomponent setting compound to the ejector body (20) so that its components mix in said body and are ejected thereby into the defect, and after displacing the ejector body along the pipe-line prior to complete setting of said compound, whilst it is in a coherent condition.
