Patent ID: 7640864

Claim:
A sidewall for a guideway, said sidewall for the guideway being attached with a ground coil for levitation, guidance and propulsion of a superconducting Maglev, said sidewall being constructed by using a fiber-reinforced cement-based mixed material, said fiber-reinforced cement-based mixed material being produced by mixing non-metallic fibers or non-magnetic metal fibers into a cement-based matrix in a mixing amount of 1 to 4% for an entire volume of the cement-based matrix, said cement-based matrix being obtained by mixing a composition with water, said composition comprising cement, aggregate grains having a maximum grain diameter of not more than 2.5 mm, pozzolana-based reaction particles having particle diameters of not more than 15 μm and a dispersant, said fiber-reinforced cement-based mixed material having mechanical properties: a compression strength of not less than 150 N/mm 2 and a tensile strength of not less than a 5N/mm 2 , said sidewall for the guideway comprising a connecting hole formed at an end face thereof and extending in an extending direction of the sidewall, and a connecting member, said connecting member comprising a central shaft portion and an outer tube made of a non-magnetic metal and slidably fitted around the central shaft portion, said connecting pipe being inserted into the connecting hole, while the exterior pipe is fixed to the connecting hole, and said sidewall for the guideway comprising a beam portion formed in the extending direction of the guideway, a plane-shaped support base seat vertically spaced downwardly from the beam portion, a wall portion to which the ground coil is to be attached and which connects the beam portion and the support base seat, and reinforcing ribs which connect a back face of the wall portion and an upper face of the support base seat and are arranged at an interval in the extending direction.
