Description

Receiving sleeve rear end cover plate and communication channel

Technical Field

The utility model relates to a tunnel construction equipment field relates to a receive sleeve rear end apron and contact passageway.

Background

The communication channel is a single channel designed to connect two tunnels. If sudden problems occur in one tunnel, such as drainage, fire, stop of operation equipment due to faults and the like, people can be transferred to the other tunnel by contacting the communication channel so as to quickly escape and rescue. At present, communication channels constructed by a mechanical method are communicated in multiple places, but because stratum reinforcement is incomplete, mechanical devices often need to use receiving sleeves to perform mechanical receiving operation after construction is completed. The traditional sleeve is used as a pressure container, the rear cover plate bears large pressure, an arc design is often adopted, and the pressure resistance of the traditional sleeve is improved. However, when work is performed in a tunnel, the work surface is narrow. The arc-shaped area cannot be fully utilized. And the arc-shaped cover plate needs to be integrally formed, so that the transportation and processing difficulty is high, and the cost is high.
