The invention relates to a method for disassembling a main drive of a double-shield TBM (tunnel boring machine) in a tunnel, which belongs to the field of disassembly and assembly and comprises the following steps: (1) preparation work; (2) cutting an anterior shield; (3) lifting lugs are welded, and lifting points are arranged; (4) disassembling and turning over by a main driving method; and (5) transporting a main drive. The in-hole dismounting key technology for the double-shield TBM main drive has the advantages that the problem of non-destructive dismounting of the main drive in a narrow space of an equipment shield body is well solved, secondary use of core components is guaranteed, the recovery cost after in-hole shell abandoning and machine dismounting is greatly saved, and the in-hole dismounting key technology is safe, economical and feasible and has wide application prospects. And the method can be used for subsequent dismounting construction of the main drive in similar in-hole shell abandoning and dismounting machines.

    本发明涉及一种双护盾TBM主驱动洞内拆卸方法,属于拆装领域,包括以下步骤:(1)准备工作;(2)切割前盾;(3)焊接吊耳以及设置吊装点;(4)主驱动法拆卸与翻身;(5)运输主驱动。本发明的优点是:本双护盾TBM主驱动洞内拆卸关键技术很好的解决了在设备盾体的狭小空间内,将主驱动进行非破坏性拆除,保证了核心部件二次使用,大大节省了洞内弃壳拆机后的恢复费用,安全、经济、可行,可用于后续类似洞内弃壳拆机中主驱动的拆卸施工。
