摘要
武汉市轨道交通三号线二标沌阳大道站~体育中心南站隧道内修复刀盘主轴承损伤齿轮。详细介绍了隧道内修复齿轮的技术措施,以及齿轮修复后盾构推进参数设置、技术措施,保证了盾构进洞,规避了隧道内无法修复而开挖竖井、吊出刀盘、返厂修复的风险。其修复技术可供类似工程参考和借鉴。
The article describes the repair of damaged cutter head gear in the tunnel of Dunyang Avenue Station ~ Sport Center Station(S) in Bid II of Wuhan Rail Traffic Line 3, and introduces the technical measures of gear repair in tunnel, and the parameter setting and technical measures of shield tunneling after gear repair, which ensures the shield tunneling in and evades the risks of excavating shaft, hoisting cutter head out and returning to factory repair because of hard to repair in tunnel. This repair technology can be referenced for the similar projects.
