System for supporting substantially rigid linear structures

A suspended supporting system and a substantially linear structure said system supporting said substantially linear structure, said structure being a pipeline, a tramway, a walkway bridge, a transportation gallery, or underwater tunnel, placed above a surface such as ground or seabed or riverbed, comprising:

• (a) said substantially linear structure is substantially rigid and has a length substantially greater than a width thereof;
• (b) means having a major axis generally parallel to a major axis of said substantially linear structure moveably attached to said substantially linear structure pulling said substantially linear structure upward, generating upward vertical force of magnitude great enough for carrying downward vertical loads and lateral loads applied to said substantially rigid structure;
• and
• (c) at least two guy ropes placed at an angle with each other, upper ends of which are attached to said linear structure and lower ends of which are attached to a footing structure placed on or anchored in said surface.
