(Summary description)

In tunnel excavation, the operational efficiency of TBM excavation determines the efficiency of the overall construction. It is widely used in railway tunnel engineering, subway tunnel engineering and other fields. With the improvement of TBM equipment manufacturing capacity, the excavation speed and the amount of slag removal are doubled. Construction costs and complexity continue to increase. How is the waste slag better transported to the ground?

QBF sidewall belt for steep inclined & vertical conveying has become a better choice, and its use can improve the speed of tunneling and achieve continuous multi-range tunneling.
