PRECAST SEGMENTS FOR ELEVATED TRANSIT RAIL STATION

摘要

The present invention relates to the segmental construction and configuration of transit rail elevated stations by inventing precast segments and specially shaped concrete planks which replace existing construction methods elevated transit rail station. Single piece of precast segments like bow-shaped segment (la, lb) combines both station viaduct and platform portions, Hybrid section (2) for concourse portion provide space for operational areas/bus way. segments erected by launching girder, pre-stressed at site and lowered over the bearing, using invented sections separate construction activity for station platform and viaduct, wider Concourse portion can be eliminated and precast planks for skywalk and entry structures.
