Prestressed concrete slab has become the primary
application for bridge construction. Our company has
striven to develop and apply new materials and construction
technologies for prestressed concrete slab
in order to reduce the construction period and to prevent
crack formation. The technologies applied to our
projects are the use of expansive concrete, the prestressing
by sequential jack-up and jack-down, and
the slab casting with the use of traveling forms. This
report presents the technical features in our designs
and construction methods of prestressed concrete
slab for bridges. |
