L-shaped retaining wall with fence foundation, compatible with top edge slant cutting type.
The "SL Retaining Wall - Multi SL-F" is an L-shaped retaining wall for road use with a protective fence foundation, designed to accommodate any longitudinal slope through sloped processing at the top of the wall (supports slopes up to 15%*1). By integrating the retaining wall and the protective fence foundation, we have significantly simplified the installation work for the protective fence and shortened the construction period. Since posts can be installed at the top of the retaining wall, the road width can be maximized. *Thanks to the specially shaped base plate, it can flexibly accommodate horizontal curves. Post holes are provided at 1-meter intervals, allowing for compatibility with protective fences and fences with post spacings of 2 meters and 3 meters. Under certain conditions, it can also accommodate slopes greater than 15%.
