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.

• Inspection hatches, manhole covers, and ditch covers
• Road construction
• Renovation and repair methods

Roads will be opened within 2 to 3 hours of implementation. The non-shrink mortar for filling materials reaches over 10 N/mm² in one hour. There is a very narrow traffic restriction area, and immediate restoration to Japan without temporary repairs is possible. The surface materials specified by the association include various resin-based and asphalt-based options. 【Features】 ○ No cut cross sections occur as it is cut in a circular shape. ○ The cutting surface is curved, preventing subsidence (steps). ○ Spherical cutting section shape and cross-section. ○ Due to its spherical shape, the cutting section can be easily raised. ● For other functions and details, please contact us.

The spherical substrate tailored to the cutting diameter has no misalignment of the substrate body, allowing for smooth cutting operations, and it also exhibits excellent substrate strength. 【Features】 ○ Noise reduction product The vibration-damping properties are enhanced due to the substrate material and shape, resulting in lower cutting noise compared to standard straight-cutting blades. Additionally, the design prevents high-frequency wind noise generated by slits in the outer circumference during blade rotation, thereby reducing noise during cutting. ○ Efficient cutting performance ○ Countermeasures against substrate wear ○ Wide versatility of blade quality ● For other functions and details, please contact us.
