FIELD: construction.
SUBSTANCE: invention relates to methods of constructing a bridge over gorges. Suspension of the bridge is carried out by means of ropes to airships. For fastening of edge airships of the bridge, stool-shaped sections are used, the horizontal legs of which are inserted into pits in the bank of the ravine, dug by industrial climbers. For nutless attachment of bridge grids of neighbouring airships to each other, folding additional sections on hinges are used, in horizontal holes on hemp-like projections of which fastening crowbars are inserted. Hemp-like ledges are arranged in the holes of the opposite section of the bridge of the adjacent airship and are pinched by the fastening bars. One fastening scrap holds two hemp-like protrusions together. If there is a difference in the height of the connected banks, the bridge is made inclined.
EFFECT: possibility of erection of bridge in hard-to-reach areas, reduction of weight of bridge, possibility of adjustment of its length.
