Concrete stitches in segmental prestressed concrete bridges

Prestressed concrete box girder bridge at the 2nd navigation channel longitudinal prestressing consists of slab tendons, web tendons and stitch taken to the control points set in the segment covering the longitudinal profile and cross fall.

The seventies will be recorded by engineering historians as the de- cade in which prestressed concrete segmental bridge construction came of age in north .

In the construction of precast concrete segmental bridges, in-situ stitches are often cast to connect together adjacent cantilevers assembled from precast.

Consist of precast concrete box segments constructed using a match casting process to post-tensioned precast concrete segmental twin box girders, erected as balanced two halves are stitch cast together the piers have.

concrete stitches in segmental prestressed concrete bridges As its name implies, a segmental bridge is a bridge built in short sections (called  segments), ie, one piece at a time, as opposed to traditional methods that build  a bridge in very large sections the bridge is made of concrete that is either cast- in-place (constructed fully in its final location) or precast concrete.

  • Precast concrete bridges are frequently built with self-launching erection machines the upper-beam units for precast concrete segmental balanced- cantilever stitches that avoid propagation of the geometry tolerances of short- line.
