AI Technical Summary
Technical Problem
Existing small pipeline renewal boring machines are difficult to effectively break the old pipes when dealing with old concrete pipes, and it is difficult to discharge slag stones.
Method used
A pipeline renewal and boring machine was designed, using a cutting board to cut old pipes, and a dirt slag slag board was installed on the cutting board. The slag board drove the slag stone upward and discharged through the conveying device. At the same time, a slag stop device is provided on the fixed body to accommodate the cut slag stone.
Benefits of technology
This equipment can effectively break old concrete pipes and ensure the smooth discharge of slag and stones, making it easy to use.
