It is a construction method that allows for low noise, vibration-free, and space-saving rapid installation in the replacement of manhole frames and covers.
This is a method ideal for replacing iron covers, characterized by speed, recyclability, and low cost. The weight of the cutter machine is 20 kg, and since it is dry, the asphalt dust generated after cutting the pavement is collected and recycled with a dust collector. By using jigs for square covers, the pavement cutting results in no leftover cutting marks, with the corners enclosed by arcs. Additionally, using recycled materials such as steel slag, traffic can be reopened at each location with cold rapid-hardening pavement materials.
