finishing with the implementation of shuttering
panels (Figure 17).
Next, the assembly of the launching nose is
installed (Figure 18). The camera is adjusted to
allow the correct visualization of this work. After
casting the first segment the displacement of this
element takes place. For that the temporary sup-
port of the nose is removed and the segment is
separated from the shuttering.

To represent the advance of the deck, the
launching equipment appears in detail, and it
consists of two parts located under each web of
deck, and thought four movements illustrated in
Figure 19, provides the launching of the segments.
This cycle is repeated until the progress of the
first segment reaches about 31 m (Figure 16).
The arrival of the nose to the first pier is
achieved during the advance of the second seg-
