basic information
○ By integrating the conventional L-shaped retaining wall with the guardrail foundation, significant cost reductions and shortened construction periods can be achieved. ○ By placing the guardrail foundation on top of the L-shaped retaining wall, not only is the width secured, but it can also be utilized for fence holes and guard pipe holes. ○ We also have options available for cohesive soil (φ=25° γS=18 kN/m³) that can accommodate backfill soil. ○ A curve-compatible type is also available, allowing for construction tailored to the site (minimum outer curve radius R=15m). ○ The safety of the retaining wall's strength against collision loads has been verified through actual structural experiments. ○ It complies with the "Guidelines for Road Earthworks Retaining Walls" and the "Standards for Guardrail Installation and Their Explanations." For inquiries regarding concrete precast products, please contact the Takamizawa Concrete Division.
