Apparatus and system for securing a hollow pile in the ground

Abstract

There is provided an apparatus for securing a hollow pile in the ground. The pile has a wall with an inner surface. The apparatus includes a first actuator and a second actuator. Each of the actuators has a central chamber, a pair of spaced-apart peripheral chambers, a pair of pistons interposed between the central chamber and the peripheral chambers, respectively, and a pair of piston rods coupled to and extending outwards from respectively ones of the pistons. The piston rods of the first actuator are shaped to form protrusions in the pile when the first actuator is actuated to move its piston rods outwards. The apparatus includes a pair of support members operatively connected to the piston rods of the second actuator. The support members are shaped to abut and support the inner surface of the pile when the second actuator is actuated to move its piston rods outwards.
