FIELD: construction. ^ SUBSTANCE: invention is related to the field of structures construction with piled foundation, in particular, to construction of marine hydrotechnical structures. Method for piles (2) jacking in ground, in which axial load for jacking is created by an according drive, differs by the fact that piles (2) are captured with the help of stepped drive, bed plate (3) of which is rigidly installed onto rod support structure (1), hydraulic jacks (5) are joined to bed plate (3) with the help of hinged joints (4), to realise stepped feed of working element arranged in the form of lock device (6), which interacts with flexible traction rods (7), having thickening (8) for stepped fixation of traction rods (7) in lock devices (6) in process of working travel of hydraulic jacks (4), at the same time flexible traction rods (7) by their one end are connected to cross beam (9), which transmits axial load to pile (2). ^ EFFECT: reduction of labour intensity and cost of pile works, by application of crane free technology. ^ 2 dwg |
