L・L Bridge Method

To extend the lifespan of aging small and medium-sized bridges! The adoption of precast products can significantly shorten construction time.

This technology allows for the reinforcement of aging small and medium-sized bridges while maintaining existing road traffic. It involves the installation of precast box culverts through horizontal pulling into the space beneath the girders, thereby integrating them to extend the lifespan of the existing bridge. It aligns with the Ministry of Land, Infrastructure, Transport and Tourism's initiative to improve productivity in concrete construction. It achieves extended lifespan, cost reduction, and shortened construction periods. 【Features】 ■ Reinforcement of aging bridges with precast box culverts ■ Construction can be carried out while keeping existing road traffic open (no detours required) ■ Achieves extended lifespan, cost reduction, and shortened construction periods ■ Adapts to the Ministry of Land, Infrastructure, Transport and Tourism's initiative for productivity improvement in concrete construction ■ Simplifies maintenance management *For more details, please refer to the PDF document or feel free to contact us.
