Abstract: An assembled subway station and a construction method thereof are provided. The assembled subway station includes a plurality of components combined in a ring shape, comprising a bottom plate component, two bottom corner components, two side wall components, a middle plate component, two top corner components, and a top plate component. Connection surfaces of each component are each provided with a concave-convex structure being matched with another concave-convex structure on a relevant connection surface of an adjacent component. Butt joint positions of two adjacent components are filled with sealing structures. The embedded grooves of two adjacent components are oppositely arranged, and connecting members for exerting opposite fastening forces on the two adjacent components are installed in the oppositely arranged embedded grooves.

Abstract: This application provides a resonator that includes a housing and a cover. A resonant rod, a dielectric block, and an elastic element are disposed in the housing. The resonant rod is in a tubular shape and includes an inner side face, an outer side face, and a first end face. The dielectric block includes a bottom end and a top end, the top end is connected to the cover, a second end face and a boss that protrudes from the second end face are disposed at the bottom end, and the boss is in an annular shape. The boss is embedded in the resonant rod a, or the boss fits around the outside of the resonant rod. The elastic element is connected between the first end face and the second end face or between the top end of the dielectric block and the cover.
