[0040] Compared with the prior art, the present invention has the following advantages:

[0041] Compared with the prior art, the advantages of the present invention are as follows:

[0042] 1) The present invention can separately simulate the axial dislocation action, horizontal dislocation action, vertical dislocation action, and rotational dislocation action of the fault, or can simultaneously simulate the axial dislocation action, horizontal dislocation action, vertical dislocation action, or rotational dislocation action of the fault; and is self-adaptively reset through the self-adaptive anti-fracture dislocation track system.

[0043] 2) The present invention accurately monitors the displacement generated by the dislocation through the oil cylinder, and then transfers the displacement to the adjusting oil cylinder in a hydraulic manner. The adjusting oil cylinder acts on the gear and the lead screw to generate real-time equal compensation displacement; realizing accurate self-adaptive anti-fracture dislocation adjustment.

[0044] 3) The present invention utilizes the self-locking ability of the lead screw. The lead screw can restrain the displacement along the lead screw direction in the static state. When the fault is dislocated, it is necessary to compensate for the displacement through the adjusting device to ensure that the track slab and the track do not displace. When the fault does not dislocate, the track slab and the track need a certain stability to ensure the smooth operation of the train. At this time, the self-locking ability of the lead screw is crucial.

[0046] 5) 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 directions are decomposed and do not affect each other.

Specific embodiments

At the same time, the advantages of the present invention will become clearer and easier to understand through the description.

[0062] An active fault zone is a zone composed of many faults. The forms 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 by tensile action, and the upper block moves downward relative to the lower block, with a relatively large dip angle; reverse faults are mainly formed by the extrusion of rock masses on both sides, and the upper block moves upward relative to the lower block. 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 by the shear action of rock masses, and the two blocks mainly move horizontally relative to each other along the fault strike, with a steep or even nearly vertical fault plane. 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 in terms of quantity, distribution area, and earthquake occurrence intensity compared with normal faults and reverse faults. There will be obvious lateral offsets in the outcropping strata of the two blocks of strike-slip faults; in addition, the fault movement may also show a movement pattern of relative rotation of the two blocks.

The vertical screw A24 drives the hinge support block A25 to move vertically on the vertical screw A24, so that the hinge A26 opens and closes, and the hinge A26 drives the corresponding segment lining to move vertically, thus realizing the simulation of the vertical dislocation action;

[0095] By rotating the first handwheel A23 of one universal joint A22 on the front of the first support plate A21, the first handwheel A23 drives the vertical screw A24 to rotate through the universal joint A22. The vertical screw A24 drives the hinge support block A25 to move vertically on the vertical screw A24, so that the hinge A26 opens and closes, and the hinge A26 drives the corresponding segment lining to rotate, thus realizing the simulation of the rotational dislocation action;

[0096] Step 4: Perform Step 1, Step 2, Step 3, and Step 4 simultaneously, and simultaneously realize the simulation of the axial dislocation action, the horizontal dislocation action, the vertical dislocation action, or the rotational dislocation action.

[0097] The self-adaptive anti-breaking and dislocation method of the self-adaptive anti-breaking and dislocation track system B is characterized by including the following steps:

[0098] Step 1: When the fault dislocates, causing the tunnel / cavity to deform and the lining 1 to have a vertical dislocation or rotational dislocation: The vertical dislocation or rotational dislocation of the lower lining 1 drives the intermediate connecting plate 11 to move vertically, 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 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 surface 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, using 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 high-speed rail.

[0099] Step 2: When the fault dislocates, causing the tunnel / cavity to deform and the lining 1 to have a horizontal dislocation: The horizontal movement of the lower lining 1 drives the lateral guide rail 46 in the subgrade 13 to move horizontally. The horizontal movement of the lateral guide rail 46 drives the horizontal push rod 222 to move horizontally through the lateral slide sleeve 43, the lateral 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 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. The nut of the horizontal adjustment ball screw 224 makes this section of the track slab 14 produce an adjustment action opposite to the horizontal dislocation; through adjustment, the track slab 14 always remains stationary, using 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 high-speed rail.

[0100] Step 3, when the simulated fault dislocates, causing 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.

[0101] Step 4, when the simulated fault dislocates, causing 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 under axial, horizontal, vertical, and even rotational dislocations are decomposed respectively and do not affect each other.

[0102] In actual use, the intermediate connecting plate 11 at the bottom of the stationary lining is successively fixed on the bottom cross bar A11 through the column A51, the bottom connecting plate A52, the bottom support plate A53, and the bottom plate A1.

[0103] 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 cylinder 211 is fixed to the side of the track slab 14 through the vertical monitoring oil cylinder cushion block 2111, and the vertical adjustment oil cylinder 213 is fixed to the bottom of the wedge top plate 142 through the vertical adjustment oil cylinder cushion block 2131; the horizontal monitoring oil cylinder 221 is fixed to the track slab 14 through the horizontal monitoring oil cylinder cushion block 2211, and the horizontal adjustment oil cylinder 223 is fixed to the top baffle 17 through the horizontal adjustment oil cylinder cushion block 2232.

[0104] The adaptive anti-fracture and dislocation track system B 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 and equal compensation displacements.

[0105] When the lining 1 rotates and dislocates, the vertical displacements to be compensated detected by the two horizontal monitoring oil cylinders 221 of this section of the lining 1 are different, resulting in different real-time equal compensation displacement values of the vertical adjustment oil cylinders 213 fixed at the left bottom of the next section of the lining 1 and the vertical adjustment oil cylinders 213 fixed on the right side of the next section of the lining 1, leading to different opening and closing distances of the two wedge block groups 215 corresponding to the vertical adjustment oil cylinders 213 moving along the inclined plane of the wedge block base 16, thus completing the adaptive anti-breaking dislocation during rotation and dislocation; the wedge block base 16 rotates along the wedge block base rotating shaft 161, and the rotating shaft base 18 is a triangular prism structure with the inclined plane facing downwards to avoid collision with the intermediate connecting plate 11.

[0106] The horizontal adjustment ball screw 224 and the vertical adjustment left and right hand ball screw 214 have self-locking capabilities. The screw can restrain the displacement along the screw direction in the static state. When there is a fault dislocation, the displacement needs to be compensated through the adjustment device to ensure that the track slab 14 and the track do not displace. When there is no fault dislocation, the track slab 14 and the track need a certain stability to ensure the smooth operation of the train. At this time, the self-locking ability of the screw is crucial.

[0107] In order to ensure that the horizontal dislocation displacement y1 of the fault is equal to the horizontally adjusted 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:

[0108]

[0109] Similarly, in order to ensure that the vertical dislocation displacement z1 of the fault is equal to the vertically adjusted displacement z2 of the control system, the radius r2 of the vertical adjustment gear 2141 and the lead s2 of the vertical adjustment left and right hand ball screw 214 should also satisfy a certain transmission ratio relationship:
