It is used as further scheme of the present utility model：The bleeder port that fills is provided with charging connector.
Compared with prior art, the beneficial effects of the utility model are：The section of jurisdiction for being used for shield tunnel accident rescue is faced
When support meanss by fast aeration formation one inflation annulus, be close to tunnel inner wall, reach to tunnel duct piece support and stably,
And the dash at initial stage in tunnel can be realized, and ensure that emergency personnel normally passes in and out, with advantages below：First, it can realize pair
Shield drive end unit tunnel duct piece is quickly supported, and delays tunnel duct piece deformation and failure process；2nd, after equipment is in place, speedily carry out rescue work
Personnel can pass through, and not influence rescue face in the range of shield machine；3rd, facility of speedily carrying out rescue work is light, with low cost, and can weigh
It is multiple to utilize.
