Shield under-pressure cabin entering multi-person gate comprehensive operation system and method

The invention provides a shield under-pressure cabin entering multi-person gate comprehensive operation system and method for pressuring and depressurizing of workers between a high-pressure working cabin and a normal-pressure working chamber of a shield machine. The shield under-pressure cabin entering multi-person gate comprehensive operation system comprises a main cabin, a front cabin and auxiliary cabins which have independent pressurizing and depressurizing functions, wherein the main cabin is in butted connection with the high-pressure working cabin, the front cabin is connected betweenthe main cabin and the normal-pressure working chamber, and the auxiliary cabins are arranged in the normal-pressure working chamber. The independent pressurizing and depressurizing main cabin and front cabin are adopted, handing-off of the operators in the cabins is achieved, the overall time of under-pressure cabin entering and depressurized going-out-of-cabin is shortened, the time loss causedby waiting for depressuri
