Abstract

The invention belongs to the technical field of civil defense doors and particularly relates to a high-speed railway tunnel escape channel concrete structure fireproof protection door. The high-speedrailway tunnel escape channel concrete structure fireproof protection door comprises a door frame, a door leaf, a hinge and a latch. The door frame is installed on a tunnel wall, and the door leaf isrotationally matched with the door frame through the hinge. The latch is installed on the door leaf and is matched with the door frame in a sliding manner. The latch comprises a base, a handle, a transmission mechanism and a lock head assembly. The base and the lock head assembly are installed on the door leaf, the handle is installed on the base, and the transmission mechanism is connected with the handle and the lock head assembly. The high-speed railway tunnel escape channel concrete structure fireproof protection door can achieve the fireproof function during locking, and the beneficial effects that locking is reliable, and opening is convenient during opening are achieved.

Description

technical field [0001] The invention belongs to the technical field of civil air defense doors. Specifically, the invention relates to a concrete structure fire protection door for evacuation passages of high-speed railway tunnels. 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 pro...
