Tunnel adaptive lining structure in complex environment and construction method thereof

A tunnel adaptive lining structure in complex environment, comprising:

• a lining;
• a pressure regulating layer, the pressure regulating layer being provided between the lining and a surrounding rock, the pressure regulating layer comprising a plurality of pressure regulating chambers, the plurality of pressure regulating chambers being spaced from each other such that spaces are formed between the plurality of pressure regulating chambers, and the plurality of pressure regulating chambers in communication with each other via connections;
• a connecting cylinder, wherein the connecting cylinder is within one of the spaces between the plurality of pressure regulating chambers;
• and
• two one-way valves, the two one-way valves being provided in the connecting cylinder;
• wherein the connections comprise an internal water connecting pipe and a plurality of connecting pipes, wherein the internal water connecting pipe is in communication with two of the plurality of pressure regulating chambers, and the internal water connecting pipe passes through the connecting cylinder, and wherein the plurality of connecting pipes are in communication with the plurality of pressure regulating chambers;
• and
• wherein the two one-way valves are oriented in opposite directions, an upper end of each of the two one-way valves is in communication with each other through a first branch pipe, and the first branch pipe is in communication with the internal water connecting pipe.
