description The invention discloses a rapid construction method for a secondary lining of a small-section tunnel. While in-tunnel cleaning is performed after tunnel holing-through, a rebar transport cart and a wheeled dumper are used for transporting and storing secondary lining rebars to a designated position in the tunnel; and after tunnel cleaning is completed, the secondary lining is constructed from thetwo ends of the tunnel to the middle at the same time, firstly, a customized inverted arch formwork is used for constructing a lower inverted arch, and then, multiple gantry-type arch wall formwork trolleys are used for following an alternative bay method to construct an upper arch wall, wherein the multiple sections of gantry-type arch wall formwork trolleys form a set and are connected in a hinged manner, which can adapt to construction of the curved tunnel. According to the rapid construction method for the secondary lining of the small-section tunnel, the single construction section is long, the process linkage is
