Installation of temporary DYWIDAG Multistrand Anchors for slope stabilization in Slovenia

Slope stabilization project "POKRITI VKOP MALECNIK", Maribor, Slovenia

SCT d.d, a local Slovenian construction firm, was awarded the contract to extensively stabilize a slope for the "SLIVNICA-PESNICA" interstate section in the village of Malecnik near Maribor on the Drava in the north of Slovenia.

The contract stipulated that the slope should be stabilized in accordance with the SIA standard of the Swiss Society of Engineers and Architects. The existing soil conditions in that region presented an additional challenge, since the soil at the site to be stabilized is mainly composed of clay dykes.

SCT d.d contacted DSI Munich and asked for their assistance in the installation of the DYWIDAG Multistrand Anchors to be used. A total of 412 temporary DYWIDAG Multistrand Anchors type 4x0.62" in lengths varying from 12-14 m with a load of 450 kN were required.

DSI Munich fabricated the first three multistrand anchors matched to the project’s requirements. In cooperation with SCT d.d, DSI Munich employees successfully installed the first DYWIDAG Multistrand Anchors on site. The subsequent testing of the DYWIDAG Multistrand Anchors conducted by DSI at a test load of 675 kN was successful. SCT d.d then installed all further anchors according to the proposal elaborated by DSI Munich to the full satisfaction of the owner.
