It gives a gentle impression with stepped stacking, and planting is possible! A case that was adopted due to its high safety evaluation!
The location for the retaining wall block installation faces the parking lot of a sports club frequented by a large number of people, emphasizing the importance of securing the landscape and safety for the future. Initially, conventional methods such as L-shaped retaining walls and reinforced earth walls were considered. However, it was pointed out that vertical walls could create a sense of oppression and that the concrete surface of the sliding face gives an inorganic impression. Concerns were also raised about the anxiety associated with deformation in the case of reinforced earth walls. On the other hand, the box-type retaining wall was adopted due to its gentle impression created by the stepped design, the ability to incorporate planting, and its high safety evaluated based on seismic resistance verification at the Public Works Research Institute and experiences from the Chuetsu earthquake. Additionally, since the construction took place in an area where a pond once existed, ground improvement and enhancement of the fill material were also carried out to ensure overall stability due to the embankment. 【Case Overview】 ■ Location: Retaining wall block installation area facing the parking lot of a sports club ■ Method: Box-type retaining wall ■ Provides a gentle impression with a stepped design and allows for planting ■ Ground improvement and enhancement of fill material were also implemented to ensure overall stability due to the embankment *For more details, please refer to the PDF document or feel free to contact us.
