5. A construction method of an assembled subway station, comprising the following steps of:
step I: prefabricating a plurality of components, providing each connection surface of each component with a concave-convex structure and C-shaped grooves, and manufacturing H-shaped steels;
step II: placing the components at butt joint positions according to an assembly sequence to make notches of the C-shaped grooves of adjacent components opposite each other;
step III: inserting the H-shaped steels into the C-shaped grooves of adjacent components to exert opposite fastening forces on two adjacent components;
step IV: pouring a high-strength grouting material into gaps between the C-shaped grooves and the H-shaped steels; and
step V: filling epoxy resin between adjacent components to achieve seal,
wherein in step I, the C-shaped channel steels are each provided with anchors, the C-shaped channel steels are pre-embedded in the connection surfaces of each component with notches outward and are connected to main steel bars of each component, and after the components are prefabricated, sealing strips are arranged on the connection surfaces of each component;
in step I, each H-shaped steel is provided with first wedge structures, the first wedge structures each have a first wedge surface arranged obliquely in a length direction of the H-shaped steels, and the C-shaped channel steels are each provided with second wedge structures; and
in step III, when the H-shaped steels are inserted, the first wedge structures of the H-shaped steels are used to form a lateral compression fit with the second wedge structures of the C-shaped channel steels of adjacent components.
