The Stone Strong system is readily adapted to a large range of geosynthetic and steel strip reinforcement as part of MSE (Mechanically Stabilized Earth) retaining wall construction. Extensive constructability and program time savings are available using large 24SF blocks compared with either small modular concrete block walls or alternatively concrete panel and strip reinforcement systems. Blocks can be placed from behind the wall using a 20 ton excavator, require no specific propping or support and can be placed 2 to 3 blocks high in advance of reinforcement installation, backfill placement and compaction.
Structurally, blocks readily accommodate construction plant surcharges such as excavators, compaction plant, piling rigs, cranes, bridge beam launch equipment and other large construction loads. MSE walls can be designed for large crane loads to facilitate placement of long span bridge beams and similar.
Additionally, there are a series of wide web and max web blocks allowing for pile diameters between 600mm and 1500mm, installed through the centre block void on multiples of 2.44m block centres. Specialist blocks are also available to accommodate cast insitu pier caps prior to beam placement as required.
MSE designs can allow for shallow bridge backseat foundations cast directly on top of the Stone Strong bridge abutment or alternatively foundations can be installed at the base of the wall with structural reinforcement used within the block voids to transfer bridge loads to ground level.
