Collapse Soil Erosion Protection Reinforced Soil Wall "QK Wall"
Collapse Soil Erosion Protection Reinforced Soil Wall "QK Wall"
Measures against landslides in steep slopes using reinforced soil walls with high shock absorption performance.
The "QK Wall" is a reinforced earth wall installed on steep slopes behind residential houses to catch collapsing soil and debris. It absorbs and disperses impact forces by receiving soil at the top edge. Since it is a soil structure that does not require significant support, it can be installed in various site conditions with minimal ground improvement or treatment. Additionally, compared to gravity retaining walls, it allows for shorter construction periods and cost reductions. ■ Measures against collapses on steep slopes behind residential houses ■ Reinforced earth wall with excellent shock absorption ■ Structure considering soil impact forces and accumulated earth pressure Ministry of Land, Infrastructure, Transport and Tourism New Technology Information System (NETIS) Registration Number: CB-090036-A *Registration period has ended *For more details, please download the PDF or feel free to contact us.

basic information
The QK wall is a composite structure composed of reinforced earth walls and protective fences. It is a structure that wraps and restrains soil with geogrids, making it possible to construct in confined spaces. A protective fence is installed at the top to ensure the volume of pockets for sediment accumulation. *For any questions or inquiries regarding products or technology, please feel free to contact us.*

Detailed information
-
Efficiently absorbs impact forces from soil and debris with reinforced earth walls, adaptable to various site conditions. QK Wall primarily uses soil and geosynthetics as its main materials. Its unique flexible structure allows for efficient shock absorption, capable of handling large-scale impact energy. Since it is a soil structure that does not require significant support, it can be installed in various site conditions with minimal ground improvement or treatment. Compared to gravity retaining walls, it enables shorter construction periods and cost reductions.
-
Construction is possible even in narrow spaces. The embankment has a shape that leans against the ground, making it suitable for sites with limited installation space, such as steep slopes behind houses and rugged terrain.
-
"Blending into the landscape without a sense of pressure" By greening the walls with vegetation, it harmonizes with the surrounding landscape. Even when vegetation is not possible, responses tailored to needs can be achieved through methods such as simulated greening.
