Three types of sidewalls, the panel, beam and directly attached coil types, were adopted as the guideway structure of the Yamanashi Maglev Test Line to evaluate their functions and clarify merits and defects. We developed the new type guideway structure taking advantage of the merits based on the evaluation results. We placed emphasis on the improvement of the efficiency of installing sidewalls to concrete roadbed, as a means to reduce the cost of construction. We discussed a shape of the sidewall in all aspects of the efficient installation, and eventually adopted an invert-T-shaped sidewall. The sidewall is fixed to the concrete roadbed with four support parts. We report the design of the support part in detail, which is a very important component for the new-type guideway structure.
