The construction of approx. 2,000 large bored piles with diameters of 90 cm to 150 cm is planned as structural piles for the new A26-Ost motorway in Hamburg. Our CCGT partner GSP mbH Mannheim is carrying out an extensive programme of dynamic test loads on test piles for this purpose. The aim is to validate the pile load-bearing capacities assumed in the planning for different pile types and geometries.
With the 54t drop weight used, characteristic pile load-bearing capacities of up to 40 MN can be tested, depending on the soil conditions. Thanks to the modular design of the drop weight, however, it is also possible to react flexibly to lower pile load-bearing capacities. In contrast to static pile test loads, dynamic pile tests - apart from the drop weight - do not require any complex loading equipment or additional reaction systems (traverses, presses, reaction piles or anchors), which results in a significant cost and time advantage.
Our partner BBI Geo- und Umwelttechnik Ingenieur-Gesellschaft mbH Geo- und Umwelttechnik GmbH Hamburg is advising DEGES Deutsche Einheit Fernstraßenplanungs- und -bau GmbH as the client of this major project from a geotechnical point of view. The static and dynamic pile test loads were planned by BBI. We look forward to continuing our excellent co-operation on this project and beyond!
