JTRF Volume 56 No. 3, Fall 2017Profile of Short Line Railroads in High GrainProduction States

The short line match-cast method of precast segments has proved to be the most versatile and reliable way to concrete bridge construction. The success of match-cast method relies heavily on accurate geometry control in precasting as the scale of adjustments during erection is very small and difficult to implement. So the required levels of accuracy in segments match-casting are stringent in order to assure erection accuracy. Therefore, the research on segments match-casting and geometry control technique of space distorted segments are very important.Based on the principle of match-casting using the short-line method, the geometry control technology of transition curve section in cross-sea bridge erected by precasting segment girder is proposed. As an example of south approach spans in north branch of Xia-zhang Cross-sea Bridge, this paper will provide a reference for the construction of similar bridges.

The Way

Based on the example of the No.4 Nanjing Yangtze River Bridge, the construction technics of precasting segmental girders by short-line is introduced. And the way of plant deformation monitoring as well as the establishment of horizontal and vertical construction control network in the precast plant are expatiated on. In addition, the measurement techniques during the installation of the fixed-mold, unfixed-mold, lineshape control techniques of the segmental girders, as well as the error correction theories during precasting process are discussed in particular. The short-line is successfully applied to the No.4 Nanjing Yangtze River Bridge, which shows its practical value in precasting segmental concrete bridges.
