Novel tunnel prefabricated inverted arch block structure

The invention provides a novel tunnel prefabricated inverted arch block structure, and relates to a tunnel prefabricated inverted arch block, the novel tunnel prefabricated inverted arch block structure comprises a prefabricated inverted arch, a bottom template is arranged on the inner bottom wall of the prefabricated inverted arch, side templates are arranged on the surfaces of the two sides of the prefabricated inverted arch, and a reinforcing steel plate is fixedly mounted on the surface of one side of each side template; end formworks are fixedly installed on the two sides of the outer face of the bottom formwork, a secondary lining inverted arch part, an inverted arch backfilling part and a pavement base layer are uniformly prefabricated into a whole through a prefabricated inverted arch, and all inverted arch construction can be completed through one-time prefabricated assembly of prefabricated inverted arch components. The connection success rate between the precast blocks is greatly improved by enlarg
