The invention relates to an assembly type corrugated steel web-steel tube composite beam and a cantilever assembly construction method thereof, and belongs to the technical field of bridge engineering or civil engineering, the composite beam comprises a main beam, a bridge deck and a shear connector, the bridge deck is formed by splicing a plurality of prefabricated slab units, wet joint concrete is arranged between adjacent prefabricated slab units, and the shear connector is connected with the main beam. The prefabricated slab units are arranged at intervals in the length direction of the main beam, and notches are formed between the upper surfaces and the lower surfaces of the prefabricated slab units in a penetrating mode. The shear connecting piece is connected to the top of the main beam in the notch, and concrete is poured in the notch. Residual stress caused after conventional welding stud welding can be avoided through the mode that the cold-bending steel plate is combined with bolt connection, the o
