A new method for maintaining and repairing manhole covers through circular ball cutting.
In the "Parabola Method," a circular cutting pavement cutter is equipped with a spherical diamond blade to cut the surface into a circular shape by rotating 360 degrees over the iron cover, and maintenance and repair work on the iron cover is carried out using non-shrink mortar. The circular cutting pavement cutter, which can be moved independently, reduces the scope of traffic regulation and allows for construction to be completed in a short time. Additionally, the removal of the cut block involves cutting the fastening bolts, and it is a quiet method that allows for detachment and removal using a lifter without the use of a crusher. Please feel free to contact us if you have any inquiries. 【Features】 ■ Accurate construction of spherical shapes ■ Construction possible at one location within 3 hours ■ Cut blocks can be removed without crushing ■ Mortar achieves strength suitable for traffic opening one hour after application, even under adverse conditions ■ Zero rubbing flat finish is possible ■ The finishing compaction process can be eliminated *For more details, please download the PDF or contact us.

Company information
Our association is implementing a parabolic method that involves attaching a spherical diamond blade to a circular cutting pavement cutter, allowing it to rotate 360 degrees to cut the surface into a circular shape on iron covers, and performing maintenance and repair work on the iron covers using non-shrink mortar. We aim to create a situation where anyone can participate with a low initial investment, establishing a smooth construction method for the repair and replacement of all iron covers on local roads, prefectural roads, and national highways.
