Abstract
For driving of ramming parts under water, a first ramming device is suspended on the supporting element and a second ramming device is suspended on a further supporting element, a submergible electrohydraulic drive unit is located laterally near or under one of the ramming device and connected with both ramming devices by hose conduits, the ramming devices with the drive unit are lowered so that at least one ramming device is placed on one ramming part and after driving it in over a predetermined path it is transferred to another ramming part, while the other ramming device drives further the first ramming part or a further ramming part, and both ramming devices are driven one after the other or simultaneously with one another by the same drive unit.
Claims23
A method of driving ramming parts under water, comprising the steps of lowering a first ramming device suspended on a first supporting element and also a submergible electrohydraulic drive unit under water;
- lowering in addition to said first ramming device also a second ramming device suspended on a second supporting element so that at least one of said ramming devices assumes a seating position on a ramming part;
- arranging the drive unit close to one of the ramming devices and connecting it with both ramming devices;
- partially driving one ramming part by said one ramming device and then transferring said one ramming device to another ramming part;
- further driving the one ramming part or a further ramming part in by the other ramming device;
- and driving both ramming devices by the same drive unit.
