High adhesion that can withstand heavy loads! Suitable for repairs in narrow spaces with a compact cutting machine.
The "Parabola Method" is a technique for repairing manhole covers that involves rotating a circular spherical blade machine to perform spherical cutting. The cutting surface with a parabolic shape has excellent adhesion and can withstand large loads. The repaired area of the circular spherical cutting surface has the characteristic of easily integrating with the surrounding pavement, and by preventing rainwater infiltration, it can prevent collapse in advance. The cutting machine and related equipment are compact and can be moved individually. This minimizes the area and duration of traffic restrictions, making it easy to carry out repairs on narrow residential roads and intersections. 【Features】 ■ High adhesion that can withstand large loads ■ Permanent construction that easily integrates with surrounding pavement ■ Collapse prevention ■ Reduction of traffic restriction area and time costs *For more details, please refer to the PDF document or feel free to contact us.

Company information
Various pipelines (such as water supply, sewage, electricity, gas, and communication) that are indispensable to our lives are laid out mainly along the roads across the country, and it is said that approximately 14 million manholes have been installed for their maintenance and preservation. As urbanization progresses and sewage facilities are established, the maintenance and preservation of these systems will become crucial. To reduce maintenance and repair costs and respond quickly, the Parabola method is essential. Understanding the main features of the Parabola cutter well and implementing it as a permanent solution rather than a temporary emergency repair is believed to contribute the most to our civic life.
