A DEEP FOUNDATION PILE (JET COATING PILE), A PRODUCTION METHOD THEREOF AND EQUIPMENTS ACCORDING TO THE METHOD

摘要

The present invention is a firm and well supported pile (20) which is obtained within the deep ground (30) as drilling the ground (30) at a specified depth by a spiral auger (3) for deep foundations that can strengthen constructions on weak grounds. It comprises a concrete column core (26) obtained from low pressure concrete (31), which is surrounded by primitive concrete jacketing (transition region) (27) being a mixture of concrete (31) with grout (32) and a coating (28) surrounding the other two structures from around and being made of a mixture of primitive concrete and soil and furthermore a primitive concrete's root like arms (29) increasing the strength by further penetrating the drilled ground (30).
