a) Straight section (Fig. 6)
- Put stakes in place every 5m along the platform (bank) and at a
distance of X = B’/2 + b at the foot of the platform bank.
- Place a taught rope on the heads of the end stakes, trying to ensure
that there are the same number of stakes on the left and on the right
of the rope. Then mark them with gypsum, lime or ashes so that they
intersect continuously at every change of direction (points of
intersection = PI).
