The invention discloses a construction method of a cantilever type retaining wall, filter tank and drainage ditch combined structure, relates to the technical field of geotechnical engineering, and aims to solve the problems that drainage ditches cannot meet design requirements easily due to the fact that drainage ditch construction is conducted after retaining wall construction is finished, and the drainage ditches are blocked easily due to rainwater with sandy soil flowing down from slope crests. The method comprises the steps that retaining wall steel bars are bound, meanwhile, drainage ditch wall and filter tank water baffle steel bars are bound, the ditch wall and a water baffle are located at the upper end of a wall toe plate, and the water baffle is located between the ditch wall and a vertical wall; a plurality of drainage pipes penetrating through the two sides of the water baffle are pre-buried, and meanwhile the cantilever type retaining wall, the ditch wall and the water baffle are poured; after t
