[0024] To achieve the above second object, the technical solution of the present invention is: an adaptive anti-fault dislocation method for a tunnel / cavity adaptive anti-fault dislocation regulation system passing through an active fault zone, which is characterized by including the following steps:

[0025] Step 1: When the fault dislocates, causing the tunnel / cavity to deform, and the lining undergoes vertical or rotational dislocation: The vertical or rotational dislocation of the lower lining drives the vertical movement of the subgrade floor, thereby acting on the vertical monitoring oil cylinder of this section of the lining through the first horizontal slide rod sleeve, vertical push rod connecting block, and vertical push rod, squeezing the hydraulic oil of the vertical monitoring oil cylinder. The hydraulic oil transfers the displacement along the pipeline to the vertical adjustment oil cylinder of the lower lining. The vertical adjustment oil cylinder drives the vertical adjustment left - right - hand ball screw through the vertical adjustment rack and vertical adjustment gear in sequence. The vertical adjustment left - right - hand ball screw drives the wedge block group to move along the inclined plane of the wedge block base through the nut, so that the two wedge blocks in the wedge block group produce an equidistant opening and closing effect on the wedge block base, realizing the vertical adjustment of the track slab; through adjustment, the track slab always remains stationary, taking this section of the track slab as the reference, that is, the target object of callback;

[0026] Step 2: When the fault dislocates, causing the tunnel / cavity to deform, and the lining undergoes horizontal dislocation: The horizontal movement of the lower lining drives the horizontal movement of the side wing guide rail in the subgrade. The horizontal movement of the side wing guide rail drives the horizontal movement of the horizontal push rod through the side wing slide sleeve, side wing rotating rod, second horizontal slide rod sleeve, second horizontal slide rod, and horizontal push rod connecting block in sequence. The horizontal movement of the horizontal push rod squeezes the horizontal monitoring oil cylinder of this section of the lining. The hydraulic oil transfers the displacement of the horizontal monitoring oil cylinder to the horizontal adjustment oil cylinder of the lower lining through the pipeline. The horizontal adjustment oil cylinder drives the horizontal adjustment ball screw to move through the horizontal adjustment rack and horizontal adjustment gear, and makes this section of the track slab produce an adjustment action opposite to the horizontal dislocation through the nut of the horizontal adjustment ball screw; through adjustment, the track slab always remains stationary, taking this section of the track slab as the reference, that is, the target object of callback;

[0027] Step 3: When the fault dislocates, causing the tunnel / cavity to deform, and the lining undergoes vertical or rotational dislocation, horizontal dislocation, and axial dislocation: The side wing slide sleeve slides along the side wing guide rail to decompose the vertical or rotational dislocation; the first horizontal slide rod slides horizontally along the first horizontal slide rod sleeve to decompose the horizontal dislocation; the side wing rotating rod slides axially along the side wing slide sleeve to decompose the axial dislocation.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] Compared with the prior art, the advantages of the present invention are as follows:

[0030] 1) The present invention accurately monitors the displacement generated by the dislocation through the oil cylinder, and then transfers the displacement to the adjustment oil cylinder in a hydraulic way. The adjustment oil cylinder acts on the gear and screw to generate real - time and equal - amount compensation displacement; realizing accurate self - adaptive anti - fault dislocation adjustment.

[0031] 2) The present invention utilizes the self-locking ability of the lead screw. When the lead screw is in a static state, it can restrict the displacement along the direction of the lead screw. When a fault dislocation occurs, a displacement compensation needs to be carried out through an adjustment device to ensure that the track slab and the track do not undergo displacement. When no fault dislocation occurs, the track slab and the track require a certain degree of stability to ensure the smooth operation of the train. At this time, the self-locking ability of the lead screw is crucial.

[0032] 3) The vertical adjustment system of the present invention includes two vertical monitoring oil cylinders located within one section of the lining and two vertical adjustment oil cylinders located within the next section of the lining; one vertical monitoring oil cylinder is fixed on the left side of the track slab of one section of the lining, and the other vertical monitoring oil cylinder is fixed on the right side of the track slab of one section of the lining. The upper end of the vertical push rod is connected to the vertical monitoring oil cylinder, and the lower end is connected to the roadbed floor; one vertical adjustment oil cylinder is fixed at the bottom left of the next section of the lining, and the other vertical adjustment oil cylinder is fixed at the bottom right of the next section of the lining; when a rotational dislocation occurs, the vertical adjustment oil cylinders located at the bottom left and right sides of the lining are respectively adjusted, and the adaptive anti-fault dislocation adjustment for the rotational dislocation can be completed.

[0033] 4) The present invention decomposes the axial, horizontal, and vertical displacements through the first sliding sleeve system and the second sliding sleeve system, ensuring that the displacement records and adjustments in the axial, horizontal, vertical, and even rotational dislocation states are decomposed and not affected by each other.

Specific embodiments

[0047] The following will describe in detail the implementation of the present invention with reference to the accompanying drawings. However, they do not constitute a limitation to the present invention and are only for illustration purposes. At the same time, the advantages of the present invention will become clearer and easier to understand through the description.

[0048] An active fault zone is a zone composed of many faults. The morphologies of faults vary greatly. According to the relative movement directions of the two fault blocks, faults can be divided into normal faults, reverse faults and strike-slip faults; normal faults are mainly formed under tensile action, with the hanging wall moving downward relative to the footwall and having a larger dip angle; reverse faults are mainly formed by the extrusion of rock masses on both sides, with the hanging wall moving upward relative to the footwall. According to the dip angle, they can be further divided into thrust faults, low-angle faults and overthrust faults; strike-slip faults are mainly formed when rock masses are subjected to shear action, and the two fault blocks mainly move horizontally relative to each other along the fault strike, with the fault plane steep or even nearly vertical. Among the linear structures on the earth's surface, strike-slip faults account for more than about 70%; in the Qinghai-Tibet Plateau region of China, strike-slip faults have an absolute advantage over normal faults and reverse faults in terms of quantity, distribution area and earthquake occurrence intensity. Obvious lateral offsets will occur in the outcropping strata of the two fault blocks of strike-slip faults; in addition, relative rotation movement patterns may also occur in the movement of faults.

[0049] Accordingly, the above-mentioned movement forms can be decomposed and summarized into 4 movement actions, including axial movement, horizontal movement, vertical movement and rotational movement; when a tunnel / cavity crosses an active fault zone, in order to adapt to the above different dislocation forms, the present invention has developed an adaptive anti-fault dislocation control system for tunnels / cavities crossing active fault zones.

[0062] An adaptive anti - fault - dislocation method for a tunnel / cavity passing through an active fault zone adaptive anti - fault - dislocation control system, characterized by comprising the following steps:

[0063] Step 1: When the fault dislocates, causing the tunnel / cavern to deform and the lining 1 to have a vertical dislocation or rotational dislocation: The vertical dislocation or rotational dislocation of the lower-section lining 1 drives the vertical movement of the subgrade floor 11, thereby acting on the vertical monitoring oil cylinder 211 of this section of the lining 1 through the first horizontal slide bar sleeve 32, the vertical push rod connecting block 31, and the vertical push rod 212, squeezing the hydraulic oil of the vertical monitoring oil cylinder 211. The hydraulic oil transfers the displacement along the pipeline to the vertical adjustment oil cylinder 213 of the lower-section lining 1. The vertical adjustment oil cylinder 213 drives the vertical adjustment positive and negative thread ball screw 214 through the vertical adjustment rack 2131 and the vertical adjustment gear 2141 in sequence. The vertical adjustment positive and negative thread ball screw 214 drives the wedge block group 215 to move along the inclined plane of the wedge block base 16 through the nut, so that the two wedge blocks 2151 in the wedge block group 215 produce an equidistant opening and closing effect on the wedge block base 16, realizing the vertical adjustment and rotational adjustment of the track slab 14; through adjustment, the track slab 14 always remains stationary, taking this section of the track slab 14 as the reference, that is, the target object of callback; in this way, it can be ensured that the monitoring reference point never changes; by designing an appropriate transmission ratio, it can be ensured that the adjustment displacement is equal to the dislocation displacement, achieving the purpose of real-time adjustment, and always ensuring that the absolute positions of the track slab and the track do not change, so as to achieve the purpose of ensuring the safe operation of the high-speed rail.

[0064] Step 2: When the fault dislocates, causing the tunnel / cavern to deform and the lining 1 to have a horizontal dislocation: The horizontal movement of the lower-section lining 1 drives the horizontal movement of the side wing guide rail 46 in the subgrade 13. The horizontal movement of the side wing guide rail 46 drives the horizontal movement of the horizontal push rod 222 through the side wing slide sleeve 43, the side wing rotating rod 45, the second horizontal slide bar sleeve 42, the second horizontal slide bar 44, and the horizontal push rod connecting block 41 in sequence. The horizontal movement of the horizontal push rod 222 squeezes the horizontal monitoring oil cylinder 221 of this section of the lining 1. The hydraulic oil transfers the displacement of the horizontal monitoring oil cylinder 221 to the horizontal adjustment oil cylinder 223 of the lower-section lining 1 through the pipeline. The horizontal adjustment oil cylinder 223 drives the horizontal adjustment ball screw 224 to move through the horizontal adjustment rack 2231 and the horizontal adjustment gear 2241. Through the nut of the horizontal adjustment ball screw 224, this section of the track slab 14 generates an adjustment action opposite to the horizontal dislocation; through adjustment, the track slab 14 always remains stationary, taking this section of the track slab 14 as the reference, that is, the target object of callback; in this way, it can be ensured that the monitoring reference point never changes; by designing an appropriate transmission ratio, it can be ensured that the adjustment displacement is equal to the dislocation displacement, achieving the purpose of real-time adjustment, and always ensuring that the absolute positions of the track slab and the track do not change, so as to achieve the purpose of ensuring the safe operation of the high-speed rail.

[0065] Step 3, when the fault dislocates, causing the tunnel / cavity to deform and the lining 1 to have an axial dislocation: A rail expansion joint adjuster (reference: [Chinese Utility Model] CN200720173517.6 Rail Expansion Joint Adjuster) is used for adjustment; in order not to affect the horizontal and vertical adjustments, one end of the first horizontal slide bar sleeve 32 is connected to the rotating shaft connection block 1111 of this section of the lining 1, and the other end is connected to the rotating shaft connection block 1111 of the next section of the lining 1 through the axial expansion slide sleeve 5.

[0066] Step 4, when the fault dislocates, causing the tunnel / cavity to deform and the lining 1 to have a vertical dislocation, rotational dislocation, horizontal dislocation, or axial dislocation: The flank slide sleeve 43 slides along the flank guide rail 46 to decompose the vertical dislocation or rotational dislocation; the first horizontal slide bar 33 slides horizontally along the first horizontal slide bar sleeve 32 to decompose the horizontal dislocation; the flank rotating rod 45 slides axially along the flank slide sleeve 43 to decompose the axial dislocation; it ensures that the displacement records and adjustments in the axial, horizontal, vertical, and even rotational dislocations are decomposed respectively and are not affected by each other.

[0067] In actual use, vertical monitoring oil cylinders 211 and horizontal monitoring oil cylinders 221 are installed on the stationary lining, and vertical adjustment oil cylinders 213 and horizontal adjustment oil cylinders 223 are not installed; the vertical monitoring oil cylinders 211 are fixed to the side of the track slab 14 through the vertical monitoring oil cylinder pads 2111, and the vertical adjustment oil cylinders 213 are fixed to the bottom of the wedge top plate 142 through the vertical adjustment oil cylinder pads 2131; the horizontal monitoring oil cylinders 221 are fixed to the track slab 14 through the horizontal monitoring oil cylinder pads 2211, and the horizontal adjustment oil cylinders 223 are fixed to the top baffle 17 through the horizontal adjustment oil cylinder pads 2232.

[0068] The adaptive anti-fracture dislocation track system 2 of the present invention accurately monitors the displacement generated by the dislocation through the horizontal monitoring oil cylinder 221 and the vertical monitoring oil cylinder 211, and then transfers the displacement to the horizontal adjustment oil cylinder 223 and the vertical adjustment oil cylinder 213 in a hydraulic manner. The horizontal adjustment oil cylinder 223 and the vertical adjustment oil cylinder 213 act on the gears and lead screws to generate real-time equal compensation displacements.

[0069] When the lining 1 has a rotational dislocation, the two horizontal monitoring oil cylinders 221 of this section of the lining 1 detect different vertical displacements that need to be compensated, resulting in different real-time equal compensation displacement values for the vertical adjustment oil cylinders 213 fixed to the left bottom of the next section of the lining 1 and the vertical adjustment oil cylinders 213 fixed to the right side of the next section of the lining 1. This causes different opening and closing distances for the two wedge block groups 215 corresponding to the vertical adjustment oil cylinders 213 to move along the inclined surface of the wedge block base 16, thus completing the adaptive anti-fracture dislocation during rotational dislocation; the wedge block base 16 rotates along the wedge block base rotating shaft 161, and the rotating shaft base 18 is a triangular column structure with an inclined surface facing downwards to avoid collision with the roadbed floor 11.

[0070] The horizontal adjustment ball screw 224 and the vertical adjustment double-thread ball screw 214 have self-locking capabilities. The screw can restrain displacement along the screw direction in the static state. When there is a fault dislocation, the displacement needs to be compensated by the adjustment device to ensure that the track slab 14 and the track do not displace. When there is no fault dislocation in the fault, the track slab 14 and the track require a certain degree of stability to ensure the smooth operation of the train. At this time, the self-locking ability of the screw is crucial.

[0071] In order to ensure that the horizontal displacement y1 of the fault dislocation is equal to the horizontal adjustment displacement y2 of the control system, the radius r1 of the horizontal adjustment gear 2241 and the lead s1 of the horizontal adjustment ball screw 224 should satisfy a certain transmission ratio relationship:

[0072]

[0073] Similarly, in order to ensure that the vertical displacement z1 of the fault dislocation is equal to the vertical adjustment displacement z2 of the control system, the radius r2 of the vertical adjustment gear 2141 and the lead s2 of the vertical adjustment double-thread ball screw 214 should also satisfy a certain transmission ratio relationship:

[0074]

[0075] Other parts not described are all part of the prior art.
