SUSPENSION
POSITIONING
Some significant cyclones which
Mozambique in the past include:
have
hit
a) Dando in the year 2012
BRIDGE´S
DECK
LIFTING
AND
Lifting and positioning was done with the assistance
of two separate sets of cables. They were
supported at the pylons. On these two cables a
crane was suspended with the ability to move
vertically and perform a 90° vertical axis rotation.
57 deck segments were lifted and positioned over
the waterway section of the bay. Seagoing Vessels
then brought the 12m long and up to 150t deck
segments one by one, each segment was lifted and
before the crane approaches the final design
elevation it rotates 90° and brought the segment to
its final position. Each steel segment had a depth
of 3m and a width of 25.6m.
b) Leon-Eline in the year 2000
c)
Domoina in the year 1984
SUMMARY
Despite the fact that the main span of the
Suspension Bridge is only 680m and it is much
shorter than the longest suspension bridges in the
world such as the Xihoumen Bridge in China which
is 1,650m (2 nd longest) and the Akashi Kaikyo Bridge
in Japan which is the longest span at 1991m, this
Bridge brings Mozambique and the whole
continent of Africa into the engineering community
with the use of an advanced level of technology
with regards to bridge construction, demonstrating
the significant ambition and achievement of a
historically unprogressive, poverty-stricken African
state.
ACKNOWLEDGEMENT
That this type of suspension bridge in Maputo -
Katembe, Mozambique was feasible to design is
thanks to a handful of international experts
worldwide with this special knowledge.
Cyclones in the South West Indian Ocean for the
period 2013 – 2014:
From the Chinese Construction Company CRBC the
main contribution was provided by Design Leader
Mr. Cai Jingwang.
From the Mozambican Authorities (Maputo Sul)
Mr. Vicente Miranda was instructive and supportive
for the Design Team and later also Mr. Basilio
Nzunga.
My honour was to be the Consultant, at the head of
the above Design Team supported by my Greek
Office Team (INSTAT SA), especially Mr. Dr.-Ing.
Aristoteles Kakaliagkos.
The orange points are wind speeds up to 350
km/h.
Finally, I want to thank GAUFF Nurnberg, especially
Mr. Stefan Tavares Bollow and Mr. Bernhard Streit
for giving me the opportunity to participate in this
impressive project.
