盾构机是隧道建设工程施工中常用的掘进工具,具有开挖地层、切削土体、搅拌渣土、输送土渣等功能,同时它还要在开挖掘进中承受大扭矩、大推力和冲击载荷,因此,盾构机的刀盘容易在掘进过程中出现变形和开裂。本文主要深入探究盾构机刀盘的修复技术,为类似研究提供一些参考。 Shield machine is commonly used in construction of tunnel construction excavation tools, with the excavation of the earth, cutting soil, mixing slag, conveying slag and other functions, but it also excavation in the high torque, high thrust and impact Therefore, the cutterhead of the shield machine is prone to deformation and cracking during excavation. This paper mainly explores the repair technology of shield cutterhead, providing some references for similar research.
