Abstract:
The present invention relates to a device for pushing four piles into the ground or into a seabed in a square configuration or in a diamond configuration, the device comprising: —a bridge assembly which defines a first, second, third and fourth connecting location arranged in a square or diamond configuration, —four connection assemblies via which in use each of the four piles is connected to the bridge assembly, wherein each pile connection assembly comprises: ∘an actuator comprising an upper actuator part and a lower actuator part, wherein the actuator is configured to extend, ∘a pile connector connected to the lower actuator part, ∘a control device configured for alternately letting each of the actuators extend, and configured for letting the pile which is pushed into the ground or seabed receive a greater force than the opposite pile of the square or diamond configuration, wherein the exerted push force is transferred into the bridge assembly and transferred at least partially from the bridge assembly as a tension force and a bending moment into the two adjoining piles via the two adjoining pile connection assemblies.
