[0002] In order to adapt to the vigorous development of China's economy, a large number of transportation infrastructure projects, including highways and railways, etc., must be built. However, the construction of these projects usually inevitably needs to pass through mountains, and the main way of passing through is through tunnels / caverns.

Especially for high-speed railways, the deformation requirements of tunnels / caverns and the track structures therein are very strict, and fault activities are likely to have a significant impact on tunnels / caverns and the structures inside the tunnels / caverns.

[0022] In order to achieve the above second object, the technical solution of the present invention is: an adaptive anti-fracture and dislocation method for a hydraulic adaptive anti-fracture and dislocation control system of a tunnel / cavity under fault dislocation, which is characterized by including the following steps:

[0023] Step 1, when a fault occurs and causes the tunnel / cavity to deform and the lining to have a vertical dislocation: the vertical dislocation of the lower lining drives the vertical movement of the subgrade floor slab, and thus acts on the vertical monitoring oil cylinder of this section of the lining through the connecting rod, horizontal sliding sleeve and vertical push rod, squeezing the hydraulic oil of the vertical monitoring oil cylinder. The hydraulic oil transfers the displacement along the oil path to the vertical adjustment oil cylinder of the lower lining. The vertical adjustment oil cylinder drives the vertical adjustment positive and negative thread ball screw through the vertical adjustment rack and vertical adjustment gear in sequence. The vertical adjustment positive and negative thread ball screw drives the two wedge block bottom supports to open and close equidistantly through the nut, so as to raise or lower the vertical adjustment wedge block and realize the vertical adjustment of the track plate; through adjustment, the track plate always remains stationary, taking the track plate of this section as the reference, that is, the target object for callback;

[0024] Step 2, when the fault dislocates, causing the tunnel / cavity to deform and the lining to have a horizontal dislocation: The horizontal movement of the lower-section lining drives the horizontal movement of the subgrade floor, and thus acts on the horizontal monitoring oil cylinder of this section of the lining through the connecting rod, horizontal sliding sleeve, vertical sliding sleeve and horizontal push rod. The hydraulic oil transfers the displacement of the horizontal monitoring oil cylinder to the horizontal adjustment oil cylinder of the lower-section 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 the nut of the horizontal adjustment ball screw causes this section of the track slab to generate an adjustment action opposite to the horizontal dislocation; through adjustment, the track slab always remains stationary, taking this section of the track slab as the reference, that is, the target object for callback.

[0025] Step 3, when the fault dislocates, causing the tunnel / cavity to deform and the lining to have a vertical dislocation and a horizontal dislocation: The horizontal push rod slides along the vertical sliding sleeve to decompose the vertical dislocation; the vertical push rod slides horizontally along the horizontal sliding sleeve to decompose the horizontal dislocation.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] Compared with the prior art, the advantages of the present invention are as follows:

[0028] 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 manner. The adjustment oil cylinder acts on the gear and screw to generate real-time equal compensation displacement; realizing accurate adaptive anti-fault dislocation adjustment.

[0029] 2) The present invention utilizes the self-locking ability of the screw. The screw can restrain the displacement along the screw direction in the static state. When the fault dislocates, it is necessary to compensate for the displacement through the adjustment 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 screw is crucial.

[0030] 3) The vertical adjustment system of the present invention includes two vertical monitoring oil cylinders located in one section of the lining and two vertical adjustment oil cylinders located in the lower 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 subgrade floor; one vertical adjustment oil cylinder is fixed at the left bottom of the lower section of the lining, and the other vertical adjustment oil cylinder is fixed at the right bottom of the lower section of the lining; when rotational dislocation occurs, the vertical adjustment oil cylinders located at the left and right bottoms of the lining are adjusted respectively, and the adaptive anti-fault dislocation adjustment of the rotational dislocation can be completed.

[0031] 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 misalignments are decomposed and not affected by each other.

Detailed implementation mode

[0043] 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. Meanwhile, the advantages of the present invention will become clearer and easier to understand through the description.

[0044] The active fault zone is a zone composed of many faults. The forms of faults vary greatly. According to the relative movement direction 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, and the hanging wall moves downward relative to the footwall, with a relatively large dip angle. Reverse faults are mainly formed by the extrusion of rock masses on both sides, and the hanging wall moves upward relative to the footwall. They can be further divided into thrust faults, low - angle faults and overthrust faults according to the dip angle. 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. Their fault planes are steep, even close to 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 - generating intensity. The two fault blocks of strike - slip faults may form obvious lateral offsets in the outcropping strata. In addition, fault movement may also cause a relative rotation movement mode between the two fault blocks.

[0045] Accordingly, the above-mentioned motion forms can be decomposed and summarized into 4 motion actions, including axial motion, horizontal motion, vertical motion, and rotational motion; when the tunnel / hole crosses the active fault zone, in order to adapt to the above different dislocation forms, the present application has developed a hydraulic self-adaptive anti-fault dislocation control system for tunnels / holes under the fault dislocation of the active fault zone.

Both ends of the horizontal adjustment ball screw 224 are connected to the top guide plate 141;

[0053] The horizontal monitoring oil cylinder 221 is connected to the horizontal adjustment oil cylinder 223 through an oil circuit.

[0061] The self - adaptive anti - fracture and dislocation method of the hydraulic self - adaptive anti - fracture and dislocation control system for tunnels / holes under fault dislocation is characterized by including the following steps:

[0062] Step 1: When the fault dislocates, causing the tunnel / hole to deform and the lining 1 to have vertical dislocation or rotational dislocation: The vertical 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 lining 1 through the connecting rod 32, the horizontal sliding sleeve 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 oil path to the vertical adjustment oil cylinder 213 of the lower - section lining 1. The vertical adjustment oil cylinder 213 drives the vertical adjustment positive - negative thread ball screw 214 through the vertical adjustment rack 2131 and the vertical adjustment gear 2141 in sequence. The vertical adjustment positive - negative thread ball screw 214 drives the two wedge - block bottom supports 215 to open and close equidistantly through the nut, so that the vertical adjustment wedge block 216 rises or falls, realizing the vertical adjustment of the track slab 14. Through adjustment, the track slab 14 always remains stationary, taking this - section track slab 14 as the reference, that is, the target object for 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 railways.

[0063] Step 2: When the fault slips, causing the tunnel / cavern to deform and the lining 1 to slip horizontally: The horizontal movement of the lower section of the lining 1 drives the horizontal movement of the subgrade floor 11, thereby acting on the horizontal monitoring oil cylinder 221 of this section of the lining 1 through the connecting rod 32, the horizontal sliding sleeve 31, the vertical sliding sleeve 41, and the horizontal push rod 222. The hydraulic oil transfers the displacement of the horizontal monitoring oil cylinder 221 to the horizontal adjustment oil cylinder 223 of the lower section of the lining 1 through the pipeline. The horizontal adjustment oil cylinder 223 drives the horizontal adjustment ball screw 224 through the horizontal adjustment rack 2231 and the horizontal adjustment gear 2241, and the nut of the horizontal adjustment ball screw 224 causes this section of the track slab 14 to generate an adjustment action opposite to the horizontal slip. 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 for 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 slip 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 railways.

[0064] Step 3, when the fault slips, causing the tunnel / cavern to deform and the lining 1 to slip axially: A rail expansion joint (reference: [Chinese Utility Model] CN200720173517.6 Rail Expansion Joint) is used for adjustment; in order not to affect the horizontal and vertical adjustments, a telescopic bushing is designed at parts such as the cross-link and the push rod.

[0065] Step 4, when the fault slips, causing the tunnel / cavern to deform and the lining 1 to slip vertically or rotationally, or horizontally: The horizontal push rod 222 slides along the vertical sliding sleeve 41 to decompose the vertical slip; the vertical push rod 212 slides horizontally along the horizontal sliding sleeve 32 to decompose the horizontal slip.

[0066] In order to ensure that the horizontal fault slip displacement y1 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:

[0067]

[0068] Similarly, in order to ensure that the vertical fault slip displacement z1 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-threaded ball screw 214 should also satisfy a certain transmission ratio relationship:

Adaptive anti-fault dislocation method of the hydraulic adaptive anti-fault dislocation regulation system for tunnels / caverns under fault dislocation, characterized in that, It includes the following steps: Step 1: When the fault dislocates, causing the tunnel / cavity to deform and the lining (1) to undergo vertical or rotational dislocation: The vertical dislocation of the lower-section lining (1) drives the vertical movement of the subgrade floor slab (11), thereby acting on the vertical monitoring oil cylinder (211) of this section of the lining (1) through the connecting rod (32), horizontal sliding sleeve (31), and vertical push rod (212), squeezing the hydraulic oil of the vertical monitoring oil cylinder (211). The hydraulic oil transfers the displacement along the oil circuit to the vertical adjustment oil cylinder (213) of the lower-section lining (1). The vertical adjustment oil cylinder (213) drives the vertical adjustment double-threaded ball screw (214) through the vertical adjustment rack (2131) and vertical adjustment gear (2141) in sequence. The vertical adjustment double-threaded ball screw (214) drives the two wedge bottom supports (215) to open and close at equal distances through the nut, so that the vertical adjustment wedge block (216) rises or falls, realizing the vertical 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 for callback; Step 2: When the fault dislocates, causing the tunnel / cavity to deform and the lining (1) to undergo horizontal dislocation: The horizontal movement of the lower-section lining (1) drives the horizontal movement of the subgrade floor slab (11), thereby acting on the horizontal monitoring oil cylinder (221) of this section of the lining (1) through the connecting rod (32), horizontal sliding sleeve (31), vertical sliding sleeve (41), and horizontal push rod (222). 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 horizontal adjustment gear (2241). The nut of the horizontal adjustment ball screw (224) causes this section of the track slab (14) to generate 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 for callback; Step 3, when the fault dislocates, causing the tunnel / cavity to deform and the lining (1) to undergo vertical or rotational dislocation and horizontal dislocation: The horizontal push rod (222) slides along the vertical sliding sleeve (41) to decompose the vertical dislocation; the vertical push rod (212) slides horizontally along the horizontal sliding sleeve (32) to decompose the horizontal dislocation.
