The connecting block (2171) of the vertical adjustment positive and negative ball screw (217) is located in the bracket limit groove (2151). The vertical linear guide rail (212) is connected to the vertical adjustment toothed plate (213) through a vertical slider (2121).
9.

10. Adaptive anti - fault - dislocation method of the adaptive pure - mechanical anti - fault - dislocation control structure for tunnels / caves crossing active faults, characterized in that Including the following steps: Step 1, when the fault dislocates, causing the tunnel / cavity to deform and the lining (1) to have a vertical dislocation: The vertical dislocation of the lining (1) in this section drives the vertical movement of the curb floor (11), thereby causing the horizontal adjustment guide plate (221) on the vertical adjustment guide plate (211) to move vertically; on the one hand, through the engagement of the first vertical adjustment gear (2161) of the lining (1) in this section with the vertical adjustment tooth plate (213) of the previous section of the lining (1) and the engagement of the second vertical adjustment gear (2162) of the lining (1) in this section with the vertical adjustment tooth plate (213) of the lining (1) in this section, the vertical adjustment tooth plate (213) is kept in an absolute fixed position. On the other hand, the first vertical adjustment gear (2161) drives the vertical adjustment positive and negative ball screw (217) to rotate through the vertical adjustment bevel gear (218). The vertical adjustment positive and negative ball screw (217) drives the two vertical adjustment guide plates (211) to open and close through the connecting block (2171), so that the lower wedges (2191) on the two vertical adjustment guide plates (211) are opened and closed at equal distances, and the upper wedges (2192) slide along the inclined surfaces of the lower wedges (2191), thereby driving the vertical movement of the track slab (14). By ensuring that the vertical adjustment displacement is equal to the vertical dislocation displacement, real-time vertical adjustment is achieved; Step 2, when the fault dislocates, causing the tunnel / cavity to deform and the lining (1) to have a horizontal dislocation: The horizontal dislocation of the lining (1) drives the horizontal dislocation of the curb (12), the roadbed (13), and the side baffle (15); on the one hand, through the engagement of the first horizontal adjustment gear (2231) of the lining (1) in this section with the horizontal adjustment rack (222) on the previous section of the lining (1) and the engagement of the second horizontal adjustment gear (2232) of the lining (1) in this section with the horizontal adjustment rack (222) on the lining (1) in this section, the horizontal adjustment rack (222) is kept in an absolute fixed position. On the other hand, through the first horizontal adjustment gear (2231) and the second horizontal adjustment gear (2232), the horizontal adjustment ball screw (225) is driven to rotate successively through the horizontal adjustment large bevel gear (224) and the horizontal adjustment small bevel gear (2251), thereby driving the horizontal movement of the track slab (14), ensuring that the adjustment displacement is equal to the horizontal dislocation displacement, and achieving real-time horizontal adjustment; Step 3, in order to ensure that the horizontal adjustment and the vertical adjustment do not affect each other, a side baffle rotating shaft (151) is installed on the side baffle (15), the roadbed (13) is sleeved on the side baffle rotating shaft (151), the bottom of the roadbed (13) is arc-shaped, universal wheels are installed at the bottom of the roadbed (13), and the curb floor (11) is slidably connected to the bottom of the roadbed (13). Through such a suspension structure, the vertical adjustment system (21) is always kept in the vertical direction.
