y - shaped support construction for increased distance for railway rolling stock

摘要

The invention is a support structure for a railed-vehicle that includes individual, unassembled components sized for easy transport. In one embodiment, the support structure includes curved columns integrally-formed with a base, the columns imparting a curved, Y-shaped configuration to the support structure. The components may be prefabricated with known materials and methods and transported to an installation site for assembly. The support structure is preferably sized to support one or two vehicle guideways. The support structure may include a pile foundation for improved support during seismic activity and to facilitate installation on existing streets and sidewalks without covering or interfering with underground plumbing or utilities. Preferably, multiple sections of the guideway are rigidly secured together through expansion joints to define a continuous guideway such that loads on the guideway are distributed over multiple columns.
