Quickly-mounted modular subway tunnel reinforcing structure and mounting method thereof

The invention provides a quickly-mounted modular subway tunnel reinforcing structure and a mounting method thereof.The quickly-mounted modular subway tunnel reinforcing structure comprises an arc-shaped reinforcing structure arranged on the inner wall of a tunnel segment lining ring, and the reinforcing structure is formed by hinging two end reinforcing modules, a plurality of standard reinforcing modules and a vault reinforcing module; the arc line of the reinforcing structure can be conveniently adjusted by rotating the reinforcing modules on the reinforcing structure during assembly so as to adapt to different tunnel segment lining rings. The arc line of the reinforcing structure is adjusted by rotating the reinforcing modules on the reinforcing structure and adjusting the number of the standard reinforcing modules, so that the reinforcing structure can adapt to tunnel segment lining rings of different sizes, and the applicability and flexibility of reinforcing are improved; and meanwhile, the end reinforc
