concrete is widely used in civil engineering structures such as
bridges, dams, reservoirs and offshore structures. The Freyssinet
multistrand system, named C Range (C for Compact System) has been
designed and developed with such structures in mind.
C Range System accommodates both external prestressing, which
is gaining wider usage particularly in bridges, as well as the
more traditional internal prestressing. The C Range was
recently approved by the EOTA (European Organisation for Technical
Approval) for use in all European Countries, according to ETAG,
the most stringent guidelines worldwide.
the past 30 years, the rapid development of cable stayed structures,
in particular cable stayed bridges,
has indicated a growing interest in this type of structure.
stay cable systems using individually protected strands
and anchorages derived from prestressing technology,
represent the state of the art in bridge engineering. Isotension,
the Freyssinet worldwide patented stressing method,
is the result of considerable investment into research and development
as well as experience from the involvement in the construction
of over 200 cable stay bridges. This method facilitates
strand-by-strand erection and virtually eliminates the need for
heavy erection equipment.
Stay Cable Technology leads the world in this form of bridge construction
and incorporates decades of experience gained from the design
and construction of some of the world's longest span cable stayed
Kanchanaphisek bridge crossing
the Chaophaya riverin an industrial area links between Bang Phli
and Suksawat. The structure is a symmetrical cable-stayed bridge
with two 950 m long pylons and a 500 m main span. The structure
has six traffic lanes. After supplying the 168 white stay cables
of the main bridge, Freyssinet and Freyssinet Thailand completed
the installation and adjustment work in June. The work lasted
12 months and involved 55 people.
Methods & Heavy Lifting
Freyssinet Group has established an enviable reputation in the
development of modern construction methods and systems for a wide
range of civil engineering structures including the following:
Insitu or precast balanced cantilever bridges
Incrementally launched bridges and viaducts
Span by span segmental erection
projects commonly require the design, fabrication and operation
of temporary works items including but not limited to erection
gantries for precast segment erection, formwork travellers for
balanced cantilever bridges and launching girders for span by
span construction of bridges and viaducts.
projects are not undertaken without the availability of considerable
technical expertise and experience. This is accomplished with
the design and consultancy organisations that are encompassed
by the Freyssinet Group who in turn employ some of the acknowledged
world leaders in such fields of engineering.
use of engineering technology within the group and of our Strand
Jacking Systems has resulted in the emergence of a heavy lifting
division that is world-renowned. Within the Freyssinet Group,
heavy lifting projects are centralised by the Swiss based
company, operating jointly with local Freyssinet subsidiaries.
range of activities covers incremental launching of bridges, erection
of offshore platforms, installation of heavy engineering structures
including boilers and towers and steel hanger roofs weighing up
to 25,000 tonnes.
