This new type of pile has high load capacity, fast construction, and low cost. In which, the hightorque drive device of the bored pile drilling machine is combined with the steel pipe pile connection part into a synchronous working device to construct steel pipe piles by the rotation method. The study also successfully manufactured and applied a design plan for this pile type with a diameter of 318.5 mm in Ha Nam. These are the first studies and tests on steel pipe pile lowering equipment with wings at the pipe tip and wall in Vietnam’s conditions, serving as a basis for deploying and applying this new technology in our country to reach high economic and technical efficiency to projects.
