Achieving the shortest construction period of just one day with a completely custom-made new cassette method, without any on-site assembly!
In recent years, there have been numerous road subsidence incidents across the country believed to be caused by concrete corrosion due to hydrogen sulfide, and this trend is expected to increase further in the future. In this renovation project, the newly developed 'D-Hole' (Docking Hole), based on a new concept, is a new cassette construction method that meets the requirements for chemical resistance, self-supporting load capacity, and impact resistance, made from PVFR material. It is a completely custom-made product that achieves a minimum construction period of just one day without any on-site assembly. 【Features】 ■ Material: PVFR manhole ■ Method: Installed inside existing manholes ■ Construction period: Minimum of 1 day ■ Construction cost: Reduced costs due to minimal civil engineering work ■ Traffic: Short regulation time *For more details, please refer to the PDF document or feel free to contact us.
