L-shaped retaining wall with the base direction used in reverse of the usual.
■ The "SL Retaining Wall / SL-R" is an effective reverse L-shaped retaining wall that is useful when it is difficult to install a heel slab due to boundary conditions of the retaining wall site or nearby structures. ■ Being a precast product, it significantly shortens construction time and achieves labor-saving and manpower-reducing effects on site work. ■ The sloped processing of the top edge of the retaining wall not only accommodates longitudinal slopes (up to a 15% slope) but also allows for flexibility. ■ The special trapezoidal shape of the bottom slab enables flexible adaptation to horizontal curves. ■ It is also possible to provide fence installation holes at the top of the retaining wall, allowing it to accommodate a wide range of site conditions. *1 Depending on conditions, it may also accommodate slopes exceeding 15%. *2 Fence hole accommodations are handled on an individual basis.
