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.
