The invention provides a pipe pile-anchor rod composite foundation capable of bearing pulling and pressing bidirectional loads and a construction technology of the pipe pile-anchor rod composite foundation. The pipe pile-anchor rod composite foundation comprises a pipe pile and an anchor rod. An anchoring hole is reserved in a foundation bottom plate of a building structure, and a stretching end anchorage device is pre-buried in the anchoring hole. The anchor rod is composed of an anchor cable and a prefabricated anchor head, and the prefabricated anchor head is buried in soil below the foundation bottom plate. The upper end of the anchor cable penetrates out of the pipe pile to stretch into the anchoring hole, and is locked by the stretching end anchorage device after being stretched. The pipe pile is supported between the foundation bottom plate and the prefabricated anchor head, and the lower end of the pipe pile is fixedly connected with the upper end of the prefabricated anchor head. In the pipe pile-anchor rod composite foundation, the prefabricated anchor head is additionally arranged at the lower end of the pipe pile so that the pressure resisting bearing capacity of the pipe pile can be improved; a waterproof curtain is formed by the pipe pile with the two closed ends, the erosion effect of underground water and the like on concrete and steel can be resisted, and the impermeability and durability of the anchor rod, the pipe pile and foundation bottom plate joints can be improved; and structural reliability and stress performance are ensured, meanwhile, project quality can be effectively improved, the construction period can be shortened, and the investment can be saved.
