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 construction 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 pavement cutting is collected and recycled using a dust collector. By using jigs for corner covers, the pavement cutting results in no leftover cuts, with the corners enclosed by arcs. Additionally, recycled materials such as steel slag are used, allowing for traffic release at each location with cold rapid-hardening pavement materials.
