| description | The invention discloses a non-destructive dismantling method of negative ring segments after a shield machine passes through an intermediate air shaft, comprising the following specific steps: step 1,enabling a segment car for transporting segments and a working platform to be in position, connecting a top segment of a first ring with a special dismantling hanger by a bolt, and then respectivelyremoving connecting bolts between the top segment and adjacent segments; and starting the special dismantling hanger to hang the top segment to the segment car; step 2, repeating step 1, and then dismantling other segments of negative ring segments of the first ring and stacking on the segment car; transporting out the negative ring segments of the first ring by the segment car; step 3, repeatingstep 1 and step 2 for dismantling negative ring segments of other rings in sequence. The non-destructive dismantling method only needs 2 to 3 workers to cooperate to dismantle the negative ring segments, thus saving manpower; a |
