Prefabricated slab type rail structure convenient for rapid construction and construction method thereof

The invention discloses a prefabricated slab type rail structure convenient for rapid construction and a construction method thereof. The rail structure is composed of steel rails, fasteners, a prefabricated slab, an isolation layer, a filling layer, an elastic buffer layer and the like. The isolation layer and the prefabricated slab can be compounded into a whole in a factory; a hole penetratingthrough a rail plate in the thickness direction is reserved in the rail plate, tbe elastic buffer layer is installed in the hole, and flexible limiting is formed after the filling layer is poured intothe hole. The filling layer is made of non-reinforced synthetic fiber concrete or steel fiber concrete; after the prefabricated slab and the isolation layer are compounded, the rail plate is positioned in a high-precision mode through plate paving equipment, and after the rail plate is fixed through a supporting device, fiber concrete is poured, and then paving of the prefabricated slab can be completed. Therefore, the pr
