Disclosed is a hole-forming pouring pile. The hole-forming pouring pile comprises a pile body; a prefabricated concrete pile wall is arranged on the periphery of the pile body and formed by concrete pipes assembled by a plurality of prefabricated concrete pieces or mixed concrete pipes and prefabricated concrete pipes assembled by the multiple prefabricated concrete pieces and serves as a wall protecting system for pile holes during pile forming; concrete expanded bodies are arranged on the outer side of the pile or at the bottom of the pile or on the outer side and at the bottom of the pile; the concrete expanded bodies of the outer side of the pile are prefabricated concrete building blocks; the concrete expanded bodies of the bottom of the pile are formed after finishing hole bottom dry operation which is performed in the pile holes of the prefabricated concrete wall protecting system of the hole walls of the pile body. By means of the hole-forming pouring pile, the problem that pile forming is hard to achieve or can not be achieved in terms of existing dry operation hole-forming pouring piles in soft soil layers, quick sand soil layers and water-contained soil layers can be solved, the pile body bearing capacity and the pile body stability are improved to the maximum degree, and the pile foundation cost can be reduced extremely.
