The invention relates to a hollow drilling pile, which comprises a pile body, spiral plates and a pile tip, wherein the pipe body is made of common steel tubes, and a plurality of spiral plates are welded on the arc surface of the pile body; the pipe tip is arranged at the lower end of the pile body, and the pile tip and the pile body are respectively provided with a plurality of injected holes; each spiral plate is composed of two semi-arced steel plates arranged at a same height; and the pipe body is provided with a plurality of ring ribs. The invention also relates to a piling construction process for a steel tube-cement soil composite pile, which is implemented through the following steps: spirally screwing the hollow drilling pile in the soil by small construction machinery; under the action of the spiral plates, loosening soil masses upwards and downwards, so that the pile body is easy to insert into the soil; injecting cement pastes into the friable soil masses through the injected holes on the pile body of the hollow drilling pile so as to form a cement-soil coated pile body. The pile and the process of the invention have the advantages of low requirement on construction space, non-field wet operation, prefabrication and short construction time, is quick and convenient in construction, can provide a large bearing capacity for a building structure, and can widely be applied to the reconstruction and extension or reinforcement of existing buildings so as to achieve the purpose of bearing the structural loads of buildings and controlling the uneven settlements of old and new buildings, meanwhile, the pile and the process of the invention also can be applied to new construction projects.
