    摘要： This disclosure relates to a pile-driving vehicle (1), comprising a chassis (11), a movement system (15) for moving the vehicle (1) on a soil, a first driving apparatus (21) and a second driving apparatus (22). Each driving apparatus (21, 22), which is intended to drive a respective pile into the soil, comprises a first member (31) that is constrained to the chassis (11), a second member (32) that is movable relative to the first member (31) along a driving line (200) and an actuating device (33) for moving the second member (32) relative to the first member (31). The movement of the second member (32) comprising an outward stroke, during which the actuating device (33) pushes the second member (32) towards the soil, applying a force on the second member (32) along the driving line (200), and a return stroke, during which the second member (32) is moved away from the soil. The second member (32) is designed to transmit the force to the pile to be driven in. The first driving apparatus (21) and the second driving apparatus (22) can be operated alternately, in such a way that the outward stroke of the second member (32) of the first driving apparatus (21) corresponds to the return stroke of the second member (32) of the second driving apparatus (22), and vice versa. This disclosure also relates to a method for driving a plurality of piles into a soil.

    摘要： A pile for strengthening and/or lifting buildings and other constructions, having a straight main line of extension and comprising a main part (2) extending along the main line of extension for most of the length of the pile (1) and comprising a lower end, designed in use to be driven into the ground (3), and an upper end (6); an upper head (4) connected to the upper end (6) and designed in use to be constrained to a foundation (5) of a building; and a connecting unit (7) which connects the upper head (4) to the upper end (6) and which allows variation of the distance between the upper head (4) and the upper end (6). The upper head (4) comprises at least an expandable body (18) designed in use to anchor to a foundation (5), and at least an actuator element (19) operatively coupled to the expandable body (18) and movable relative to the expandable body (18) between a first position corresponding to a non-expanded condition of the expandable body (18), and a second position corresponding to an expanded condition of the expandable body (18). The pile is used in a strengthening method.
