Fortec was contracted by Austral/Rio Tinto to carry out the installation and testing of permanent soil nails and supply, placement and to strengthen existing ROM Wall to enable upgrading of ROM and mine.
The works were complete within the existing ROM structure and required specialised Fortec Australia owned plant and equipment due to the restricted working room and installation of works at height up 6m vertically.
Due to the unique project requirements. Testing of soil nails were required to meet Rio Tinto and TfNSW specifications.
Each individual self drilling soil nail has an ultimate material capacity of 1200kN with a self weight of approx. 150kg each. Fortecs plant and systems reduced manual handling and greatly improved safety.
In a single operation, the carousel will handle, install and grout 3 No 76mm dia self drilling anchors at 3m long each that are mechanically connected in place and at height during the installation process.
