The invention discloses a boat-shaped pipe section towing protection tool and a construction method thereof. The protection tool comprises a pipe section protection groove, pipe section protection caps and towing rings, wherein the pipe section protection groove is in a half-pipe shape, the cross section of the pipe section protection groove is a semicircular arc, the two ends of the pipe section protection groove are each connected with one pipe section protection cap, each pipe section protection cap is composed of a cap tip and a cap section, the conical tip of each cap tip faces outwards, the conical bottom of each cap tip is connected with one end of the corresponding cap section, the other end of each cap section is fixedly connected with the pipe section protection groove, a through hole is formed in the middle of each towing ring, and one towing ring is fixedly connected to the cap section of each pipe section protection cap. Pipe sections are conveyed along hillsides through the boat-shaped pipe section towing protection tool, scratching of large-diameter pipe sections can be effectively avoided, pipes cannot collide with soil and stone in the process of moving along steep hillsides, resistance can be reduced, sandy soil can be prevented from entering the pipes, and welding grooves of the pipe sections can be effectively protected.
