METHODS, SYSTEMS AND APPARATUSES FOR SEGMENTAL DUCT COUPLERS

摘要

The subject matter disclosed herein relates to methods, systems and apparatuses for segmental duct couplers for use during and after formation of concrete segments. Segmental duct coupling systems can include a number of components for coupling ducts both during and after formation of the concrete segments. In one aspect, the coupling system can include a locking member and forming member disposed between coupling ends of segmental ducts. In another aspect, a coupling system can include a deformable member disposed between coupling ends of ducts cast within pre-cast and match-cast concrete segments.
