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) to accommodate backfill soil. - A curved 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 real structure experiments. - It complies with the "Guidelines for Road Earthwork Retaining Walls" and the "Standards and Explanations for Guardrail Installation."
