Installing pipeline segments within a conduit

2- The method of claim 1, further comprising:

• aligning a respective main axis of each respective pipe segment of additional one or more pipe segment of the pipeline with the main axis of the pipeline;
• lifting the each respective pipe segment from a first position associated with the bottom end of the conduit to a respective position adjacent to a previously installed pipe segment;
• abutting a top rim of the each respective pipe segment against a bottom rim of the previously installed pipe segment;
• and
• attaching the top rim of the each respective pipe segment to the bottom rim of the previously installed pipe segment.

4- The method of claim 1, wherein lifting the second pipe segment comprises lifting the second pipe segment utilizing a lifting mechanism coupled to the second pipe segment, the lifting mechanism comprising:

• a lifting assembly comprising a chain sling, the chain sling comprising:
• a main hook;
• a plurality of connecting hooks releasably connected to an inner surface of the second pipe segment;
• and
• a plurality of chains interconnecting the plurality of connecting hooks and the main hook;
• and
• a winch coupled to the main hook utilizing a main cable, wherein lifting the second pipe segment comprises winding up the main cable utilizing the winch.

6- The method of claim 4, wherein each retractable wheel of the plurality of retractable wheels comprises:

• a retractable arm pivotally coupled to the outer surface of the cylindrical frame from a first end of the retractable arm;
• and
• a wheel rotatably coupled to a second opposing end of the retractable arm,
• wherein extending the plurality of retractable wheels between the outer surface of the cylindrical frame and the inner surface of the second pipe segment comprises pivotally rotating the retractable arm from a retracted position to an extended position, a main axis of the retractable arm parallel to a main axis of the cylindrical frame in the retracted position, the main axis of the retractable arm perpendicular to the main axis of the cylindrical frame in the extended position, and
• wherein the plurality of retractable wheels are equally spaced apart around a periphery of the outer surface of the cylindrical frame.

8- The method of claim 6, wherein the retractable mechanism comprises:

• a main frame fixedly coupled to the cylindrical frame;
• a secondary frame;
• and
• a plurality of two-link mechanisms interconnecting the main frame and the secondary frame, each two-link mechanism of the plurality of two-link mechanisms comprising:
• a first link pivotally coupled to the secondary frame utilizing a first pivot joint;
• and
• a second link pivotally coupled to the main frame utilizing a second pivot joint, the second link and the first link interconnected utilizing a third pivot joint;
• and
• a plurality of wheels, each wheel of the plurality of wheels coupled to a respective third pivot joint of a respective two-link mechanism, wherein each wheel rotates around a respective second pivot joint responsive to linearly moving the secondary frame along a main axis of the main frame.
