Abstract
A device is provided for the movement and mutual assembly of segments of an excavation battery. The device includes four parts: an upper joint, a lower joint, a flexible element and a stop element. The upper joint is connectable to a driving tube. The lower joint is connectable to one segment of the excavation battery. The flexible element connects the upper joint to the lower joint so that the lower joint slides along the flexible element. The stop element limits the sliding of the lower joint away from the upper joint, and includes a ballast with a diameter that is less than a diameter of an inner duct in one segment of the excavation battery.
