Abstract
According to the method for achieving arbitrary alignment of the bridge structure (1) (usually box cross section) with incremental launching technology one foresees manufacturing of concrete bar. The concrete bar (3) is in principle a bar under the webs (vertical walls) (2) of the bridge structure (1) of variable thickness, or height. The bridge construction (1) has usually two webs (2) therefore two concrete bars (3) are necessary. The concrete bars (3) are of approximately equal width as webs (2) and are continuous along the whole length of the bridge. The third dimension, i.e. height or thickness (d=f (x) ) of said concrete bar (3) has variable value in such a way that in its lower part it corresponds to theoretical geometrical conditions for launching, and in its upper part it corresponds to arbitrary designed alignment according to bridge construction requirements.
