Problems solved by technology

[0002] The communication channel of the subway shield tunnel is a communication channel connecting two parallel subway shield tunnels. It is a hole in the hole. There is no very effective way to solve emergency accidents in the construction process. Most construction methods are to randomly install a steel plate at the door of the communication passage for protection. Small

Abstract

The invention discloses a subway shield tunnel connection channel safety door. The subway shield tunnel connection channel safety door comprises a connection flange, a front door frame and a sliding door, wherein a horizontal door frame mounting platform is arranged at the bottom end of a connecting flange installed on the side walls of a shield tunnel on the two sides of a connection channel; thebottom of the front door frame is mounted on the door frame mounting platform; the periphery of the outer side of the front door frame is connected with the connecting flange through an upper door frame, a side door plate and a lower door frame, two sides of the side door plate are connected and reinforced with the connecting flange through stiffening plates, an upper chute and a lower chute arearranged on the upper portion and the lower portion of the inner side face of the front door frame respectively, and the top and the bottom of the sliding door are slidably mounted in the upper chuteand the lower chute respectively. When emergency accidents such as sand gushing and water gushing happen to the subway shield tunnel, the communication channel can be closed in time, and the loss of the built subway shield tunnel caused by the emergency accidents is reduced to the minimum.

Description

technical field [0001] The invention relates to the technical field of subway shield tunnel construction, in particular to a safety door for a communication channel of a subway shield tunnel. Background technique [0002] The communication channel of the subway shield tunnel is a communication channel connecting two parallel subway shield tunnels. It is a hole in the hole. There is no very effective way to solve emergency accidents in the construction process. Most construction methods are to randomly install a steel plate at the door of the communication passage for protection. Small. Contents of the invention [0003] Aiming at the problems existing in the background technology, the present invention proposes a safety door for the communication channel of a subway shield tunnel. The purpose of the invention is to close the communication channel in time if emergency accidents such as sand gushing and water gushing occur during the construction of the communication channe...
