Excavation installation

Excavation installation, comprising excavation means in which more than one excavation means is positioned next to another in a row of excavation means, in which multiples of such rows of excavation means are positioned behind one another, and in which the excavation means of a particular row are offset with regard to the excavation means of an adjacent row, such that in use the excavation installation may excavate a horizontal bottom of water in a direction that is perpendicular to the direction of the rows of excavation means, in which the excavation means are connected to a rigid construction positioned vertically above the excavation means by means of a resilient connection in order to absorb the vertical impact loads on the excavation means and to transmit these impacts to the rigid construction, and in which the rigid construction is resiliently connected to a bridge that is positioned vertically above the rigid construction, in which the bridge is connected to the rigid construction by means of linear actuators, in such a way that, during use, the linear actuators exert an adjustable and vertical pressing force onto the excavation means.
