Abstract

The invention provides a starting and receiving sealing device for a connecting passage tunneling machine adopting a mechanical method. The problem that during construction of a connecting passage inthe prior art, a construction stratum needs to be frozen is solved, and the starting and receiving sealing device has the advantages of being delicate in structure, easy and convenient to operate, economic and practical. The starting and receiving sealing device comprises a starting steel sleeve, a receiving steel sleeve, the connecting passage tunneling machine and a connecting passage. The starting steel sleeve is arranged on a starting tunnel portal of the connecting passage; sealing brushes and grease joints are arranged on the starting steel sleeve, and the grease joints are connected with grease pipelines; the receiving steel sleeve is arranged on a receiving tunnel portal of the connecting passage; and the connecting passage tunneling machine is connected with connecting passage support segments. According to the starting and receiving sealing device for the connecting passage tunneling machine adopting the mechanical method, stratum reinforcement is not needed, the problem thatduring construction of the conventional connecting passage, an excavated stratum needs to be frozen is effectively solved, the positive and effective solving scheme is provided for actual construction, the construction efficiency is greatly improved, and the production cost of enterprises is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of tunnel boring machines, in particular to a starting and receiving sealing device of a boring machine for a mechanical communication channel. Background technique [0002] According to the "Metro Design Code" stipulates that "in the construction of urban rail transit, when the continuous length of the tunnel is greater than 600 meters, a connecting channel should be set up between two single-line interval tunnels" for fire evacuation. In urban rail transit, due to Most of the lines are located under roads and buildings, and do not have the conditions for open excavation or ground reinforcement. Therefore, the freezing method is introduced as the reinforcement condition, and the mining method is used for underground excavation for the construction of the communication channel. Due to the limitation of the process, the freezing method has a large construction cost. Risks and safety hazards, not only the safe...
