Cantilever Retaining Wall
Cantilevered retaining walls are typically used in cut excavations [Fig.1] [Fig.2]. Nevertheless, they can be used also for fill applications. Due to their narrow base width, cantilevered retaining walls are suitable for those situations with tight space constraints or right-of-way constraints. retaining wall soil load
Mt Magometon Quarry
The crushing plant is constructed on the side of the incline adjacent to the quarrying area. On each side of the incoming crushing hopper large 5500mm high "wing" retaining walls were originally built out of vertical hardwood sleepers & steel I beams. The timber sleepers had rotted away threatening the structural integrity of the wall.
Classification of Wing Walls | Wing Walls in Bridges
