Abstract

The invention belongs to the technical field of civil defense doors and particularly relates to a moveable-threshold fireproof protective airtight door of an escape route of a high-speed railway tunnel. The moveable-threshold fireproof protective airtight door comprises a door frame, a door leaf, hinges, closing locks, a movable threshold and a sealing device. The door frame is installed on a tunnel wall. The door leaf is rotationally matched with the door frame through the hinges. The closing locks are installed on the door frame and are in sliding fit with the door frame. The movable threshold is installed at the bottom of the door frame and connected with the tunnel wall. When the door leaf is closed, the movable threshold abuts against the bottom of the door leaf. The sealing device isinstalled on the door frame and the door leaf. When the door leaf is closed, the door leaf is pressed to the movable threshold in an embedded manner. By arranging the movable threshold, the installation condition of the protective door is improved, a step is not needed when the protective door is installed, and the moveable-threshold fireproof protective airtight door has the feature of convenient construction. Meanwhile, the movable threshold can be detached, so that materials and personnel can conveniently pass, and therefore the moveable-threshold fireproof protective airtight door also the feature of high passage capacity.

Description

technical field [0001] The invention belongs to the technical field of civil air defense doors, in particular, the invention relates to a high-speed railway tunnel evacuation channel living threshold fire protection airtight door. Background technique [0002] While high-speed railways bring high efficiency and convenience to human beings, railway accidents have also caused huge economic losses and social impacts. As a key node of high-speed railway, traffic safety in the tunnel has always been the focus of railway operation and management. Because the railway tunnel is relatively airtight, it is difficult for trains to exhaust smoke and dissipate heat in the tunnel when a fire occurs, so high-temperature and toxic smoke will be generated quickly. In addition, there are few tunnel entrances and exits, poor ventilation and lighting conditions, high concentration of personnel, and difficulty in evacuation. Rescue is difficult, and it is easy to cause heavy casualties and prop...
