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 parabolic-shaped cutting surface 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. The cutting machine and related equipment are compact and can be moved individually. This minimizes the traffic regulation area, 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 regulation area and time costs *For more details, please refer to the PDF document or feel free to contact us.

Company information
Various pipelines (water supply, sewage, electricity, gas, communication, etc.), which are essential arteries of our lives, are laid out mainly along the roads across the country, and it is said that about 14 million manholes have been installed for their maintenance and preservation. With rapid urbanization and the implementation of sewage facilities, the maintenance and preservation of these systems will become an important point in the future. To reduce maintenance and repair costs and respond quickly, the Parabola method is indispensable. Understanding the key features of the Parabola cutter well and implementing it as a permanent construction rather than a temporary emergency repair is believed to contribute the most to our civic life.
