Product for relining sewers and water pipes

Abstract

A method is disclosed for relining buried pipeline with interconnectable plastic type pipe sections. The method comprises gaining acess to an open end of the buried pipeline, such as through a manhole, passing pipe sections down the manhole and inserting individually each pipe section into the buried pipeline open end. Each pipe section is of a length to permit, within the confines of the manhole, insertion of each pipe section into the pipeline open end. Each pipe is of a diameter to fit within the pipeline. The pipe section to be inserted is interconnected to the pipe section already inserted within the buried pipeline. Such interconnected sections are sequentially moved into the buried pipeline to permit insertion of the next pipe section into buried pipeline until the entire length of the pipeline to the next access area has been relined.
