Description

Technical Field

[0001] This invention belongs to the field of tunnel boring machine technology and relates to a slag discharge device for a vertical curve small-turn inclined shaft TBM and an inclined shaft TBM. Background Technology

[0002] In existing technologies, the drill-and-blast method is commonly used for the construction of water diversion tunnels in pumped-storage power stations. However, this method suffers from low efficiency, high construction risk, and significant environmental impact. Therefore, to address these technical challenges, a novel TBM (Tunnel Boring Machine) designed for inclined shafts with ultra-small vertical curves and steep gradients has been developed to improve the construction efficiency and safety of water diversion tunnels in pumped-storage power stations. The quality of the inclined shaft muck removal system, a key feature of this new TBM model, directly impacts the overall construction efficiency of the inclined shaft TBM.

[0003] Currently, the TBM slag chute system for small-radius vertical curve turns and steep inclines has the following problems: ① The inclined shaft slag chute system cannot adapt to the ultra-small radius (RR50m or less) vertical curve turns of the TBM; ② Collect debris around the shield and gravel behind the support boot; ③ The open-type TBM with main beam is difficult to achieve small-radius vertical curve turning. Therefore, the slag chute system of the TBM with small-radius vertical curve turning and large slope of the inclined shaft needs to be designed for the new type of open-type TBM with shield articulation. ④ When the slope of the inclined shaft is large, it is necessary to control the amount of slag discharged and the speed of slag sliding. ⑤ The belt conveyor slag removal system is only suitable for slag removal from TBMs in inclined shafts with small slopes; ⑥. Transportation of cutting tools for steep inclined shafts is difficult. Summary of the Invention
