The invention belongs to the technical field of tunnel construction, and discloses a negative ring duct piece hoisting dismantling assembly and dismantling method. The negative ring duct piece hoisting and dismantling assembly comprises a first hoisting tool, a second hoisting tool and a third hoisting tool which are used for hoisting the negative ring duct pieces on the top, the side and the bottom correspondingly. The first lifting appliance comprises a first lifting rod, a first lifting lug and a locking piece, the first lifting rod penetrates through the negative ring duct piece, one end of the first lifting rod is detachably connected with the locking piece, and the other end of the first lifting rod is detachably connected with the lifting lug. The second lifting appliance comprises a second lifting rod and second lifting lugs, the second lifting rod penetrates through the negative ring duct piece, and the second lifting lugs are detachably installed at the two ends of the second lifting rod respectively. And the third lifting appliance comprises a connecting piece, a third lifting lug and a clamping piece, one end of the connecting piece is connected with the third lifting lug, the other end of the connecting piece is rotationally connected with the clamping piece, and the clamping piece can penetrate through the negative ring duct piece and abut against the negative ring duct piece. The first lifting appliance, the second lifting appliance and the third lifting appliance can lift, disassemble and assemble the negative ring duct pieces at different positions, efficient and safe disassembly of the negative ring duct pieces is achieved, smooth disassembly is guaranteed, and the duct pieces are prevented from being damaged.
