The invention relates to a securing means and a method for securing a civil engineering element to a construction machine by means of a flexible securing element, wherein a first end of the flexible securing element is attached to the construction machine and a second end is provided with a connecting link which can pass through a securing lug on the civil engineering element and can be releasably fastened to the construction machine by a connecting means. According to the invention, a detection unit is provided on the connecting means, which detection unit is designed for identifying fastening of the connecting link to the connecting means. The detection unit can generate and output a signal if fastening of the connecting link is identified.

The invention relates to a pile-driving device and a method for driving driving material into a ground, wherein, for the purpose of driving-in, the driving material is clamped and held by means of a clamping means on a pile-driving power unit and prior to clamping the driving material is connected by means of a flexible securing element, in particular a securing chain, to the pile-driving power unit. In accordance with the invention a pressing element is provided which is displaced relative to the pile-driving power unit towards the driving material and, in doing so, a pressing force is applied onto an upward-directed front face of the driving material.

The present invention relates to a method of power management during pile foundation having a base machine for excavating a borehole and an attachment installed at the base machine for a simultaneous introduction of a casing into the ground, wherein the energy supply for the attachment is at least partially provided by the base machine and a control of the base machine dynamically regulates the energy flow from the base machine to the attachment.

Disclosed is a nesting element for use in a hollow pile. The nesting element is configured to be retained at an opening defined in a wall of the pile. The nesting element comprises a surface that is configured such that, in use, the surface substantially conforms to an internal profile at a transverse cross-section of the pile. Also disclosed are a pile system that employs one or more nesting elements in one or more respective piles, and an installation system for installing the pile system into the ground. Additionally, a method of constructing a retaining wall using the pile system and installation system is disclosed.

Certain aspects of removing submerged piles of offshore production platforms can be implemented as methods. A top deck of a fixed offshore platform installed on a mudline of a body of water is removed. An upper structure of the fixed offshore platform is removed. The upper structure is below the top deck. A lower structure is secured to the mudline by one or more structural piles remaining. The one or more structural piles, which are housed within one or more members of the lower structure, are driven below the mudline. The lower structure of the fixe offshore platform is removed. The one or more structural piles are left below the mudline.
