A rapid construction method for a secondary lining of a small-section tunnel includes steps of: transporting and store secondary lining steel bars to a designated position in the tunnel with a steel bar transport vehicle and a wheel type dump truck; after the tunnel is cleaned, simultaneously constructing the secondary lining from two ends to a middle of the tunnel; constructing a lower inverted arch with a customized inverted arch formwork and then constructing an upper arch wall with a plurality of portal arch wall formwork trolleys; wherein the portal arch wall formwork trolleys form a set, and are connected by hinges, so as to construct in a curve tunnel. The rapid construction method has a long single construction section, and procedure connection is compact, thereby realizing rapid and efficient construction of the secondary lining.
