About This Product
A box-shaped retaining wall is a type of retaining wall that was developed based on the stone walls of castles found throughout Japan. The entire structure is constructed using a box-shaped box and wall materials (single-grained crushed stone, split stone, etc.) that are stacked in a step-like manner.
■Features
The box-type retaining wall construction method has been adopted in various regions as a construction method that is superior in earthquake resistance, safety, environmental friendliness, ease of construction, and economic efficiency.
1. Earthquake resistance
Because it has a flexible structure, it reduces the stress generated by the wall's minute behavior in response to earth pressure during an earthquake, and prevents the retaining wall from cracking or collapsing. In addition, the ground reaction force is relatively small, and it is able to follow uneven settlement of the foundation ground and backing soil, maintaining the stability of the entire retaining wall.
2, Safety
A layer of single-grained crushed stone has extremely high drainage, which naturally stabilizes the backing soil.
3.Economy
At the construction site, special work such as reinforcing steel, concrete, and formwork is rarely used, which significantly shortens construction time and improves economic efficiency.
4. Workability
Curve construction is easy. The stairway shape has a three-dimensional beauty, and by building on a temple slope in addition to a fixed slope, you can save land. Additionally, by flipping the product, you can easily secure the ends.
5. Environmental
You can also consider preserving the ecosystem by planting trees using each small tier or creating natural greenery. Small steps also have various properties such as providing a passage for animals, mitigating falling snow on slopes, guiding the line of sight for vehicles, and reducing visibility obstructions around curves.
