1. A pile-driver assembly for driving a pile into the ground, the assembly including:
a casing defining a chamber, the chamber being configured to house a fluid;
a positioning element configured to position the casing at or on the pile, wherein at least a portion of the positioning element is positioned between the chamber and the pile; and
actuating means comprising at least one actuator, wherein the actuating means comprises a central moving element, having an extended position and a retracted position, wherein the actuating means comprises a buffering chamber, configured to house a buffering fluid, wherein the buffering chamber is configured so that the volume of the buffering chamber decreases as the central moving element moves from the extended position to the retracted position, wherein the actuating means comprises regulating means comprising one or more valves configured to regulate internal buffering characteristics of the actuating means, wherein the one or more valves are configured to control the amount of buffering fluid within the buffering chamber,
wherein the actuating means is configured to be actuated to displace the chamber relative to the positioning element, such that the chamber moves away from the pile, and
wherein the actuating means is configured to be actuated to release the chamber for displacement towards the pile such that a force is exerted by the chamber on the positioning element, to controllably drive the pile into the ground.
