Figure 6.55 A view of the external
vertical columns with upper telescopes
of at least 120 kN were designed. The suspension draw bars are made of circular bars
with threads at the free end. The marginal supporting brackets are connected to the upper
chords of the main girders of pipeline bridge (Figure 6.55); internal vertical brackets are
fitted on the original binders of the bridge. As well as the system of pipeline, a new type
of saddle with lower telescopes and sufficient compression capacity in the springs were
devised (Figure 6.56). These tools are fitted to the original bridge binders (Figures 6.57
and 6.58).
