AIR BAG TYPE TUNNEL ENTRANCE BLOCKING APPARATUS

摘要

The present invention relates to an air tube type tunnel entrance blocking apparatus which minimizes the concern about failure due to a simple structure thereof, performs a rapid work, and prevents the generation of safety accidents to the maximum. The air tube type tunnel entrance blocking apparatus according to the present invention comprises: at least one pillar (10) that is disposed at the entrance of a tunnel and vertically on one side of a road; an air tube (32) which expands toward the road and has a warning of entry prohibition marked on the surface thereof; an air tube module (30) equipped with an inflator injecting air into or expanding the air tube (32); and a control unit (50) that is a body separated from an air tube module and which transmits operational signals to the inflator (34) depending on a detection signal sent from a tunnel malfunction detection sensor including a fire detection sensor inside the tunnel or on an external operation.
