The present invention discloses an apparatus (100) for tracing pile set during pile driving of a pile (150) comprising: a panel (110) for attaching to the pile (150); a rotatable holding mechanism (120) with remotely controllable function for holding a writing instrument (160) against the panel (110) to trace the pile set for at least a series of blows during the pile driving; a sliding mechanism (130) with remotely controllable function, which slides on a pair of bearing strips (131′, 131″) to provide lateral movement of the holding mechanism (120) across the panel (110) after each blow of the pile driving; and a platform (140) with groves for holding the bearing strips (131′, 131″) in place for allowing the sliding mechanism (130) to slide freely in multiple directions; characterized in that, the holding mechanism has a rotatable lever arm (126) which is secured by a resilient means (129′) to reduce excess vibration so that the writing instrument (160) is held in a still position while allowing the lever arm (126) to be rotated by motor controlled arm (127) during the tracing of pile set.

The invention relates to a system with markers for placing a retaining pile with asymmetrical reinforcement and method for using same, so that the reinforcement is disposed in the correct position. The system comprises at least one positioned separator and a marker-separator attached to transverse reinforcing means, at least one marker disposed on a guide wall or sleeve, the marker-separator being aligned with the marker or separated by a distance equal to or less than a predetermined safety value. The method for using the system comprises the steps of: positioning a separator and attaching a marker-separator to the transverse reinforcing means, positioning the marker on the guide wall or sleeve; aligning the marker-separator with the marker or positioning at a distance equal to or less than a predetermined safety value, when the asymmetrical reinforcement is placed inside the guide wall or sleeve.

A lead for installing a pile into a seabed floor comprising: an elongated body extending longitudinally along a first axis in a first direction from a top end to a bottom end and configured to receive a pile oriented in the first direction; and a lead indexing foot attached to the bottom end of the elongated body and laterally offset with regard to the first axis.

A civil engineering device, in particular a pile-driving or drilling device, has at least one positioner, in particular a working carriage for accommodating an implement, connected with a carrier device by relatively movable links within a kinematic chain and connected by joints and/or linear adjusters and with at least six actuators for changing their corresponding position and/or orientation, and with a control and regulation device for controlling them. The control and regulation device has an input module for specifying a positioner target position, and is connected with a computer module that determines at least one displacement path for moving the positioner from its current (starting) position to the target position, and, using inverse kinematics, the locations of the individual actuators required for implementing the path, and sends these locations to the control and regulation device to control the actuators. A method multi-dimensionally, free positions a civil engineering device positioner.
