发明名称 Support structure
摘要 An improved support structure capable of supporting a guideway in the form of a tube or tubes which may in turn carry a train for travel thereupon, which elevated guideway is capable of passing over existing right-of-ways, rolling or mountainous terrain, and rivers of moderate size. The improved support structure provides a uniform vertical thermal expansion and uniform loading deflection (due to the weight of a passing train) thus assuring that the elevated tubes are smooth and straight.
