The invention discloses a tunnel TBM disassembly system which can be used for disassembly of two TBMs tunneling oppositely in the same tunnel, earth excavation is reduced, the construction period is shortened, and economic benefits are improved. The tunnel TBM disassembling system is arranged in a tunnel formed through TBM construction and comprises a receiving cavern, a retreating area, a blasting buffering area and a disassembling cavern which are sequentially arranged in the direction opposite to the tunneling direction of a first TBM. The receiving cavern is formed in the mode that the first TBM conducts tunneling to the engineering midpoint and then retreats, and is used for receiving the second TBM conducting tunneling opposite to the first TBM; after the first TBM retreats, the cutterhead and the main machine are located in the retreating area, and the disassembly cavern is formed by blasting excavation after a trolley and a bridge frame of the first TBM are disassembled; the disassembly cavern comprises a cutterhead overturning area, an equipment disassembly area and a loading transportation area, and the cutterhead overturning area, the equipment disassembly area and the loading transportation area are sequentially arranged in the backward direction of the first TBM.
本发明公开了一种隧道TBM拆机系统,能够用于同一条隧道内相向掘进的两台TBM的拆机,减少了土方开挖、缩短了施工周期、提升了经济效益。上述隧道TBM拆机系统设置于TBM施工成型的隧道内,包括沿第一TBM掘进的相反方向依次设置的接收洞室、后退区、爆破缓冲区和拆机洞室;接收洞室由第一TBM掘进至工程中点后倒退形成,用于接收与第一TBM对向掘进的第二TBM;第一TBM倒退后的刀盘和主机位于后退区内,拆机洞室在第一TBM的台车和桥架拆除后爆破开挖形成;拆机洞室包括刀盘翻转区、设备拆解区和装车运输区,刀盘翻转区、设备拆解区和装车运输区沿第一TBM倒退的方向依次设置。
