Summary:The utility model discloses a bypass tunnel structure for treating tunnel collapse. The structure includes a method for treating a collapse section (4) of a main tunnel (1), and is characterized in that the method comprises the steps of excavating at least one bypass tunnel (2) to bypass the collapse section (4) of the main tunnel (1) and then turn back to the main tunnel (1), and excavating in the reverse direction in back of the collapse section (4) of the main tunnel (1) and treating the collapse section (4). The structure can safely and conveniently treat tunnel collapse, and can furthest reduce the influence on the project duration by collapse, compared with the method of repeated treatment in repeated collapse when the collapse section is treated in the forward direction, the structure greatly reduces the collapse treatment risk and investment, and has remarkable economic benefits and social benefits.
