Installing pipeline segments within a conduit

A method for installing a pipeline within a conduit, the method comprising:

• securing a first pipe segment of the pipeline at a top end of the conduit, a main axis of the first pipe segment coinciding with a main axis of the pipeline;
• aligning a main axis of a second pipe segment of the pipeline with the main axis of the pipeline;
• lifting the second pipe segment from a first position associated with a bottom end of the conduit to a second position adjacent to the first pipe segment, lifting the second pipe segment comprising maintaining an alignment between the main axis of the second pipe segment and the main axis of the pipeline utilizing the lifting assembly, the lifting assembly further comprising:
• a cylindrical frame coaxially disposed within the second pipe segment, maintaining an alignment between the main axis of the second pipe segment and the main axis of the pipeline comprising maintaining a first gap between an outer surface of the cylindrical frame and an inner surface of the second pipe segment constant by extending a plurality of retractable wheels between the outer surface of the cylindrical frame and the inner surface of the second pipe segment;
• abutting a top rim of the second pipe segment against a bottom rim of the first pipe segment;
• and
• attaching the top rim of the second pipe segment to the bottom rim of the first pipe segment.
