The invention relates to an underground gallery movable wood beam plywood formwork trolley composed of at least one trolley unit. Each trolley unit comprises wall formworks arranged on two sides, an arch crown formwork connected to the tops of the two wall formworks, and a cross plate supporting frame for supporting and connecting the wall formworks with the arch crown formwork. Compared with the prior art, the underground gallery movable wood beam plywood formwork trolley is simple in structure, high in strength, low in weight, convenient to retrofit and capable of saving materials. Arranged connecting holes are used for fast connection, so that formwork setup time is short, the number of staff is reduced, and efficacy is improved. Joint molding is good, and project quality is improved. The mechanized construction degree is higher, labor intensity is relieved, and working efficiency is improved. The large-size formworks are adopted so that concrete pouring quality can be improved.
