In subway construction, the connecting channel is generally located in the middle of the section tunnel. It is a connecting channel between the section tunnel and ancillary caverns such as the fan room and sewage pump room. It is also a construction channel and ventilation and disaster prevention channel for the section tunnel. The construction of connecting channels is a major source of danger, especially the construction of connecting channels in water-rich and sandy strata, which is prone to water and sand gushing accidents. In order to be able to block the connecting channel from the shield tunnel in time in an emergency, it is usually practice to install emergency flood prevention doors at the excavation entrance of the connecting channel.

[0003] A Chinese patent discloses an emergency flood prevention door for use in the construction of a communication channel (authorization announcement number CN216811780U). The patented technology is easy to install, stable and reliable, and has a good sealing effect.
