Tunnel fault-resistant section device and construction method thereof

The invention relates to the technical field of tunnel construction, in particular to a tunnel fault-resistant section device and a construction method thereof.The tunnel fault-resistant section device comprises surrounding rock, anchor rods, lithosphere, fault-resistant section assemblies and a tunnel body; the anti-error section assembly comprises a foam concrete buffer layer, a steel pipe, a concrete stable ground, a bottom supply mechanism, a side wall mechanism, a primary lining mechanism and a secondary lining; when the ground layer is dislocated, the sensor can receive deformation generated by the dislocated and transmit data to the receiver and the controller device, so that the bottom supply mechanism and the side wall mechanism can generate elongation or shrinkage with the same displacement, it is guaranteed that the tunnel structure is not damaged, and therefore the problem that an existing tunnel structure is prone to being damaged is solved. 本发明涉及隧洞施工技术领域，具体涉及一种隧洞抗错段装置及其施工方法，隧洞抗错段装置包括围岩、锚杆、岩石圈、抗错
