The invention discloses an assembly type steel tube recycled concrete pile which comprises a bottom steel tube, at least one unit steel tube, a loading plate and a drill bit. External threads are formed in respective top outer walls of the bottom steel tube and the unit steel tubes; internal threads are formed in respective bottom inner walls of the bottom steel tube and the unit steel tubes; threaded blades are welded to respective outer walls of the bottom steel tube and the unit steel tubes; first fixing rings are fixedly welded to positions on the respective top outer walls of the bottom steel tube and the unit steel tubes and located under the external threads; and second fixing rings are fixedly welded to positions on the respective bottom outer walls of the bottom steel tube and theunit steel tubes and located above the internal threads. Inner steel tubes are fixed in respective inner centers of the bottom steel tube and the unit steel tubes; and recyclable concrete blocks andself-compacting concretes can be injected into the inner steel tubes from the top part of the uppermost unit steel tube. The cost is effectively reduced, and meanwhile, the concrete pile can be easily, sectionally, sequentially and rotatably driven into the ground.
