Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] refer to Figure 1 to Figure 4 , a water-conducting sealing device for shield tunnel joints according to the present invention, comprising an arc-shaped rubber band 4 extending across the caulking 3 and along the segment joint 9, on the inner surface of the arc-shaped rubber band 4 The anti-filter layer 5 is fixedly set. The lateral sides of the arc-shaped rubber belt 4 form a detachable connection with the segment 1 through the bolts 7 arranged at vertical intervals, so that the inner surfaces of the lateral sides of the arc-shaped rubber band 4 are closely attached to the segment 1 to form a seal. The filter layer 5 is in close contact with the caulking 3 . It can realize the complete sealing and water conduction of the joints of the segments, avoiding the adverse effects of water leakage from the joints on the tunnel; the arc-shaped rubber b...
