We would like to introduce the "Jizai R RS Foundation" that we handle. Due to its bolt connection structure, there is no need for ready-mixed concrete, allowing for same-day backfilling and significantly reducing construction time compared to conventional methods. It can flexibly adapt to curves like a chain, and there is no need for diagonal cutting of the base plate, with the outer radius accommodating a minimum of 10R. The use of a balancing beam-type support construction method improves the workability of protective fences. 【Features】 ■ Bolt connection structure, no need for ready-mixed concrete ■ Same-day backfilling possible ■ Significant reduction in construction time ■ Flexibly adapts to curves like a chain ■ Outer radius accommodates a minimum of 10R *For more details, please refer to the PDF document or feel free to contact us.
