Based on the "Guidelines for Road Earthworks - Retaining Wall Works [Japan Road Association (Public Corporation)]" and the "Large Block Retaining Wall Design and Construction Manual [Shikoku Branch of the Japan Society of Civil Engineers (Public Corporation)]," the product types consist of two types with wall face slope (1:0.5), effective width (150 cm), and effective height (H=35・70 cm), and five types of control lengths (50・75・100・125・150 cm). Large block retaining walls are constructed by stacking individual blocks, making the strength of the interlocking joints between the blocks crucial. Our company has conducted strength tests on the interlocking joints, and experimental results have confirmed that they possess greater shear resistance. We have obtained brightness and texture certificates from the Japan National Concrete Block Association (Public Corporation). 【Features】 ■ Greater shear resistance ■ Easy construction due to horizontal stacking *For more details, please refer to the PDF materials or feel free to contact us.
