DYWIDAG salvages a Trench Cutter in Surfers Paradise
Das Unternehmen Keller Foundations war gerade dabei, in Surfers Paradise in Queensland, Australien eine Schlitzwand für eine 5-stöckige unterirdische Parkgarage zu erstellen, als eine Schlitzwandfräse in einer Tiefe von 25 m stecken blieb.
Solution
After several failed attempts to lift the equipment with a crane, Keller Foundations asked DYWIDAG to help. An experienced team of experts immediately came to the jobsite and offered the required special services.
Within only 3 days, 75mm Ø high tensile DYWIDAG Post-Tensioning Bars including couplers and stressing nuts as well as two HOZ 5400 bar jacks with R11.2 pumps were shipped to the jobsite. DYWIDAG also provided a specialized post-tensioning operator to jack the trench cutter upwards to the surface.
Due to the special nature of this job, Keller Foundations placed a great deal of emphasis on precise coordination and the required safety protocols.
The 75mm Ø DYWIDAG Post-Tensioning Bars were equipped with giant fish hooks that hooked into the hoist points of the machine down in the slurry. After an 8 hour jacking operation with an initial 160t load and an average load of 60t at a later stage, the cutter was successfully salvaged by a proud crew and a very happy client.
After a 4 week project delay, the Keller Foundations crew was able to recommence the deep slurry wall excavation thanks to the support of DYWIDAG.
