Soldier pile retention, Eastern Freeway upgrade
64 soldier piles up to 750 mm diameter forming an engineered retention wall along a freeway widening corridor. Capping beam and shotcrete infill in-house.
A freeway widening project needed 110 metres of engineered retention along a cut-and-fill corridor adjacent to live traffic. The design called for 64 soldier piles up to 750 mm diameter, embedded between 8 and 14 metres deep, with shotcrete infill between piles and a continuous capping beam along the top.
We programmed the soldier installation inside the principal’s traffic management envelope, poured the capping beam after a 7-day cure, and applied the shotcrete infill in panels as the freeway widening excavation progressed.
The complete retention system was certified by our chartered engineer and handed across to the principal’s design coordinator on schedule.
