Depending on the geological environment, high geothermal tunnels may appear in certain areas. During the construction of high geothermal tunnels, phase change concrete is needed to reinforce the high geothermal tunnels. In order to make the high geothermal tunnels and phase change concrete more solid, anchor rods are also needed to support them between the high geothermal tunnels and the phase change concrete.

[0029] like Figures 5 to 11 As shown, when anchor rods are used to install support for the reinforcement layer between the high geothermal tunnel and the phase change concrete, it is often necessary to drill holes around the inner wall of the reinforcement layer first, then pour concrete into the holes, and then manually insert the anchor rods into the reserved holes with the help of auxiliary tools. Since there are many holes and required anchor rods, and they are distributed in different positions of the tunnel, it is impossible to use pneumatic pushing to efficiently insert the basalt fiber anchor rods into the high geothermal tunnel on the basis of precise positioning. This is time-consuming and labor-intensive, with high labor costs and easy delays in tunnel construction.

The swing frame 44 is driven by the swing arm 42 through the connector 43 to swing back and forth horizontally, and then the pistons 46 on the two groups of push rods 45 are driven to reciprocate in the two groups of cylinder barrels 3 to generate pressurized gas, which is then supplied to the two groups of air storage cylinders 48 for temporary storage through the two groups of exhaust pipes 47. Both sides of the swing frame 44 are fixedly connected to the limit sliders 9, and the bottoms of both sides of the inner cavity of the fixed box 1 are provided with limit slide grooves 10 that slide with the limit sliders 9 to provide sliding support compensation for the two ends of the swing frame 44, thereby improving the stability of the horizontal back and forth displacement of the swing frame 44. Pressure sensors 11 are embedded in the tops of the outer sides of the two groups of air cylinders 48 to monitor the pressure in the two groups of air cylinders 48 in real time.

[0030] The rotating assembly 5 includes an electric push rod 51, which is embedded in the other output shaft of the double-headed motor 41, and the piston rod of the electric push rod 51 is fixedly connected to the driving bevel gear 52, and a driven bevel gear 53 is provided above the driving bevel gear 52. The electric push rod 51 adjusts the meshing position of the driving bevel gear 52 and the driven bevel gear 53, and the inner cavity of the driven bevel gear 53 is fixedly connected to a connecting rod 54 that is rotatably matched with the fixed box 1 and the fixed frame 2. Both ends of the connecting rod 54 are fixedly connected to a driving circular gear 55, and the teeth of the driving circular gear 55 are meshed with a gear ring 56.

The outer side of the two sets of gear rings 56 is fixedly connected to a connecting piece 57, and a sliding piece 58 is provided on the outer side of the connecting piece 57. The two sets of driving circular gears 55 on the connecting rod 54 drive the connecting piece 57 and the sliding piece 58 on the two sets of gear rings 56 to perform synchronous rotation adjustment; The outer walls of the two sets of gear rings 56 are fixedly connected to the annular slide 12, and the inner cavity of the fixed frame 2 is provided with an annular slide rail 13 that slides with the annular slide 12, which serves as a rotational support for the two sets of gear rings 56 and improves the rotational stability of the two sets of gear rings 56. The top of the outer side of the two sets of fixed frames 2 is provided with an arc-shaped slide groove 14 that slides with the connecting member 57, which serves as a sliding limit for the connecting member 57, and a scale line groove is provided on the side of the fixed frame 2 close to the arc-shaped slide groove 14 to display the rotation angle of the slide 58.

[0031] The pushing assembly 6 includes a first three-way valve 61, two groups of first three-way valves 61 are connected to the first exhaust port of the air storage cylinder 48, and the bottom end of the first three-way valve 61 is connected to a delivery pipe 62, the ends of the two groups of delivery pipes 62 are connected to a connecting joint 63, and the inner end of the connecting joint 63 is rotatably connected to a rotary joint 64, the channels of the two groups of connecting joints 63 and the rotary joint 64 are in a connected state, the inner ends of the two groups of rotary joints 64 are connected to a hollow tube 65 that rotates with the fixed frame 2, the two groups of hollow tubes 65 are slidably connected to the sliding member 58, and the ends of the hollow tubes 65 are connected to a pushing cylinder 66, which controls the opening of the two groups of first three-way valves 61 of the pushing assembly 6 and supplies the pressurized gas in the two groups of air storage cylinders 48 into the two groups of pushing cylinders 66 through the two groups of delivery pipes 62, the connecting joint 63, the rotary joint 64 and the hollow tube 65; The exhaust ports of the two groups of push cylinders 66 are connected to a first pressure relief pipe 67, and the first pressure relief pipe 67 is provided with a first pressure relief valve. The two groups of push cylinders 66 are fixedly connected to elastic ropes 68 around the hollow tube 65, and the other end of the elastic rope 68 is fixedly connected to a push seat 69 that slides with the push cylinder 66. The two groups of push cylinders 66 are connected to a discharge head on the side away from the hollow tube 65. Under the action of the boost pressure in the two groups of push cylinders 66, the push seat 69 is forced to push forward. At the same time, the two groups of sliding members 58 in the angle adjustment state drive the two groups of push cylinders 66 to rotate accordingly, accurately aligning with the hole position after filling with concrete, which facilitates the pushing of the basalt fiber anchor rod 78. An angle sensor 15 is fixedly connected to the center of the outer side of the two groups of pushing cylinders 66 to detect the rotation angle of the two groups of pushing cylinders 66, and a limited guide block 16 is fixedly connected to the center of the inner side of the pushing cylinder 66. The inner side of the two groups of limited guide blocks 16 is slidably connected with an arc-shaped guide frame 17 fixedly matched with the fixed box 1 and the cylinder barrel 3, which plays a role of sliding limit for the pushing cylinder 66 in the angle rotation adjustment state, improves the rotation stability of the pushing cylinder 66, and also provides a support for the pushing cylinder 66 in the initial state; The two groups of pushing cylinders 66 are fixedly connected to the two sides near the discharge head with a positioning camera 18 and a laser head 19, which are used to shoot and locate the holes in front of the discharge heads of the two groups of pushing cylinders 66 to improve the accuracy of inserting the anchor rods into the holes.

The positioning camera 18 and the laser head 19 are distributed in an inclined state along the horizontal axis of the pushing cylinder 66 toward the discharge head.

[0032] The feeding assembly 7 includes a material storage box 71. The two groups of material storage boxes 71 are connected to the feeding port of the pushing cylinder 66. A card slot 72 is provided on the inner side of the top of the inner cavity of the material storage box 71. A feeding port 73 is provided on the outer side of the two groups of material storage boxes 71 near the pushing cylinder 66. The outer side of the material storage box 71 near the feeding port 73 is fixedly connected to an electric cylinder 74. The piston rods of the two groups of electric cylinders 74 are fixedly connected to a baffle plate 75 that is engaged with the card slot 72. The opening and closing between the two groups of baffle plates 75 and the card slot 72 are controlled by the frequency of the two groups of electric cylinders 74. Limiting springs 76 are embedded on both sides of the bottom of the inner cavity of the storage box 71. The tops of the two sets of limiting springs 76 are fixedly connected to limiting plates 77 that slide with the storage box 71. The tops of the limiting plates 77 are provided with basalt fiber anchor rods 78 that cooperate with the baffle plate 75. Under the elastic extrusion force of the two sets of limiting springs 76 and the limiting plates 77, the basalt fiber anchor rods 78 filled into the storage box 71 through the loading port 73 are automatically loaded. The two groups of storage boxes 71 are fixedly connected to the two sides away from the feeding port 73 with clamps 20, and the inner cavity of the feeding port 73 is clamped with a sealing plate 21 used in conjunction with the clamp 20 to seal the feeding port 73. After the sealing plate 21 is removed from the feeding port 73, it can be placed in the clamp 20 for temporary storage. Vertical grooves 22 are provided on both sides of the two groups of storage boxes 71, and the inner cavity of the vertical grooves 22 is slidably connected with a pinching ear 23 fixedly matched with the limit plate 77, which presses down the limit plate 77 to facilitate the filling work of the basalt fiber anchor rod 78.

[0033] like Figure 12 and Figure 13 As shown, due to the different heights of tunnels, when anchor rods are used to install support for the reinforcement layer between the high geothermal tunnel and the phase change concrete, their height cannot be adaptively adjusted, resulting in the anchor rods not being inserted into the hole position, affecting the overall support and stability performance of the anchor rods for the high geothermal tunnel and the phase change concrete. Adjustment components 8 used in conjunction with the supply component 4 are provided around the fixing box 1. The adjustment component 8 includes a second three-way valve 81. The two groups of second three-way valves 81 are connected to the second exhaust ports of the two groups of gas storage cylinders 48, and both ends of the second three-way valve 81 are connected to a branch pipe 82. The ends of the two groups of branch pipes 82 are connected to a sealing cylinder 83 fixedly matched with the fixing box 1. The pressurized gas in the two groups of gas storage cylinders 48 is supplied to the upper end space of the inner cavity of the four groups of sealing cylinders 83 by the two groups of second three-way valves 81 through the two groups of branch pipes 82. The top of the inner cavity of the four sets of sealing cylinders 83 is fixedly connected with a buffer spring 85, and the bottom of the buffer spring 85 is fixedly connected with a T-shaped rod 86 that slides with the sealing cylinder 83. As the four-way pressurized gas continues to accumulate in the upper end space of the inner cavity of the four sets of sealing cylinders 83, the pressure in the upper end space of the inner cavity of the four sets of sealing cylinders 83 increases. Under the action of the pressure force, the four sets of T-shaped rods 86 are forced to move downward, and the four sets of buffer springs 85 are stretched. The exhaust port of the four sets of sealing cylinders 83 is connected to the second pressure relief pipe 84, and the second pressure relief valve is provided on the second pressure relief pipe 84. When it is necessary to discharge the pressurized gas in the upper end space of the inner cavity of the four sets of sealing cylinders 83, the second pressure relief valve on the four sets of second pressure relief pipes 84 can be controlled to open, and the pressurized gas in the upper end space of the inner cavity of the four sets of sealing cylinders 83 is discharged from the four sets of second pressure relief pipes 84, which facilitates the reset of the four sets of T-shaped rods 86. The bottoms of the four sets of T-shaped rods 86 are fixedly connected to supports 87, and the inner sides of the supports 87 are fixedly connected to electric motors 88. The output shafts of the four sets of electric motors 88 are fixedly connected to Mecanum wheels 89. The four sets of T-shaped rods 86 that move downward synchronously drive the supports 87 to apply downward pressure to the ground. Because the four sets of Mecanum wheels 89 are in contact with the tunnel surface, the downward pressure generated by the four sets of T-shaped rods 86 drives the fixed box 1 as a whole to be lifted upward, achieving a height adjustment effect, which is beneficial to the installation of anchor rods in tunnels of different heights.

[0034] Specifically, the working principle of the high geothermal tunnel basalt fiber anchor support construction device is as follows: after the holes and concrete in the reinforcement layer between the high geothermal tunnel and the phase change concrete are drilled and filled in succession, the double-headed motor 41 is first controlled to start and drive the swing arm 42 to rotate at high speed, and the two sets of limit sliders 9 and the limit slide grooves 10 provide sliding support compensation for the two ends of the swing frame 44, then the connecting head 43 on the swing arm 42 drives the swing frame 44 to swing back and forth horizontally, and the swing frame 44 in the horizontal back and forth swinging state drives the pistons 46 on the two sets of push rods 45 to perform reciprocating work in the two sets of cylinder barrels 3, and the two sets of air intake pipes provide gas to the two sets of pistons 46 in the return state in the two sets of cylinder barrels 3 until the two sets of pistons 46 return After the air is inhaled to the maximum value, the air intake valves on the two air intake pipes are closed. At this time, the two pistons 46 perform a process action in the two cylinder barrels 3 and compress the inhaled gas to generate pressurized gas. After the two pistons 46 are compressed to the maximum value in the two cylinder barrels 3, the exhaust valves on the two exhaust pipes 47 are closed. In this reciprocating manner, the two pistons 46 perform reciprocating work in the two cylinder barrels 3 to generate pressurized gas, and the pressurized gas is supplied to the two air storage cylinders 48 through the two exhaust pipes 47 for temporary storage. At the same time, the pressure in the two air storage cylinders 48 is monitored in real time by the two pressure sensors 11 until the pressure in the two air storage cylinders 48 reaches the maximum safe value, and the double-headed motor 41 is controlled to be turned off. According to the height of the opening of the hole in the tunnel, when the height adjustment is required, the two sets of second three-way valves 81 are controlled to open, and the pressurized gas in the two sets of gas storage cylinders 48 is synchronously supplied to the four sets of sealing cylinders 83 through the four branch pipes 82 by the two sets of second three-way valves 81, and is gathered in the upper end space of the inner cavity of the four sets of sealing cylinders 83 and generates supercharged pressure. Under the action of the supercharged pressure, the four sets of T-shaped rods 86 are forced to slide downward in the four sets of sealing cylinders 83, and the four sets of buffer springs 85 are stretched downward. At the same time, the four sets of T-shaped rods 86 drive the four sets of The Mecanum wheels 89 on the supports 87 exert downward pressure on the tunnel surface. Because the four sets of Mecanum wheels 89 are in contact with the tunnel surface, they generate an upward reaction force on the fixed box 1. The four sets of T-shaped rods 86 drive the fixed box 1 upward to a predetermined height, then close the two sets of second three-way valves 81, stopping the supply of pressurized gas to the four sets of sealing cylinders 83. Then, the four sets of electric motors 88 are controlled to drive the four sets of Mecanum wheels 89 to move the fixed box 1 to the optimal insertion position for the basalt fiber anchor rods 78 in the center of the tunnel. If the fixed box 1 needs to be lowered, the second pressure relief valves on the four sets of second pressure relief pipes 84 can be synchronously controlled to open, and the pressurized gas in the four sets of sealing cylinders 83 will be discharged through the four sets of second pressure relief pipes 84. Under the downward pressure of the entire gravity of the fixed box 1, the four sets of T-shaped rods 86, which have lost the pressure of the pressurized gas, will quickly slide upward and reset in the four sets of sealing cylinders 83. Then, the four sets of buffer springs 85 will offset the impact force generated by the four sets of T-shaped rods 86 after sliding upward and resetting, so as to prevent the four sets of T-shaped rods 86 from colliding with the upper ends of the four sets of sealing cylinders 83 after resetting. After the height position is adjusted to the right position, the blocking plates 21 in the two sets of feeding ports 73 are respectively pulled out and temporarily placed in the clamps 20 on the two sets of storage boxes 71. Then, the two sets of pinching ears 23 are respectively pinched and pressed down in the two sets of vertical slots 22. The two sets of pinching ears 23 drive the two sets of limit plates 77 to press down, and also drive the two sets of limit springs 76 to compress downward. Then, two batches of basalt fiber anchor rods 78 prepared in advance are placed on the two sets of limit plates 77 through the opened two sets of feeding ports 73. After the two sets of storage boxes 71 are filled with basalt fiber anchor rods 78, the pinching ears 23 are released. Under the upward squeezing action of the two sets of limit springs 76, the two sets of limit plates 77 are used to squeeze the installed basalt fiber anchor rods 78 upward, and the two sets of baffle plates 75 are used to squeeze the upward squeezing state. After the basalt fiber anchor rod 78 is blocked, the sealing plate 21 is re-inserted into the loading port 73. After the basalt fiber anchor rod 78 is loaded, the electric push rod 51 is first controlled to open and drive the driving bevel gear 52 to move up to the meshing portion of the driven bevel gear 53. Then the double-headed motor 41 is controlled to open and drive the connecting rod 54 on the driven bevel gear 53 to rotate at a low speed through the driving bevel gear 52. The connecting rod 54 drives the two sets of driving circular gears 55 to rotate at a low speed. The two sets of annular slides 12 and the annular slide rails 13 provide rotation support compensation for the two sets of gear rings 56. Then the two sets of gear rings 56 drive the two sets of connecting parts 57 to rotate slowly from the initial points of the two sets of arc chutes 14. The two sets of connecting parts 57 then drive the two sets of sliding parts 58 to adjust their angles accordingly. At the same time, since the two groups of hollow tubes 65 are rotatably connected to the two groups of fixing frames 2, with the center points of the two groups of fixing frames 2 as the center of the circle, the two groups of limit guide blocks 16 and the arc guide frames 17 provide sliding limit compensation for the two groups of pushing cylinders 66, and the two groups of sliding members 58 in the slow angle adjustment state drive the pushing cylinders 66 on the two groups of hollow tubes 65 to rotate with the center point of the circle. At the same time, the two groups of angle sensors 15 detect the adjustment angles of the two groups of pushing cylinders 66, and when the two groups of hollow tubes 65 rotate, they also drive the two groups of connecting joints 63 to rotate in the two groups of rotating joints 64. The two groups of positioning cameras 18 position and shoot the front images of the two groups of pushing cylinders 66 in the slow angle adjustment state, and the two groups of laser heads 19 perform positioning and shooting of the current hole positions. Laser marking is performed so that workers can recheck and confirm the current hole position. When the discharge ports of the two groups of pushing cylinders 66 reach the first group of hole positions on the tunnel, and the number of holes in this group is two, the two groups of electric cylinders 74 are controlled to open and quickly drive the two groups of blocking plates 75 to fall off the two groups of slots 72. Under the elastic squeezing force of the two groups of limit springs 76, the two groups of limit plates 77 are forced to drive the basalt fiber anchor rods 78 in the two groups of storage boxes 71 upward to the two groups of pushing cylinders 66 and after being located in front of the two groups of pushing seats 69, the two groups of electric cylinders 74 are immediately controlled to close and quickly drive the two groups of blocking plates 75 to re-engage the two groups of slots 72, and block the next group of basalt fiber anchor rods 78 in the two groups of storage boxes 71. After the two basalt fiber anchor rods 78 reach the front of the pushing seats 69 in the two groups of pushing cylinders 66, the two groups of first three-way valves 61 are controlled to open, and the pressurized gas in the two groups of gas storage cylinders 48 is supplied to the two groups of hollow tubes 65 by the two groups of delivery pipes 62 through the two groups of interconnected connecting joints 63 and the rotating joints 64, and then supplied to the head end space of the two groups of pushing cylinders 66 by the two groups of hollow tubes 65 and gathered to form a supercharged pressure. Under the action of the supercharged pressure, the two groups of pushing seats 69 are forced to slide forward in the two groups of pushing cylinders 66, and drive the two groups of elastic ropes 68 to stretch. The two groups of pushing seats 69 in the forward sliding state drive the current two basalt fiber anchor rods 78 to slide forward in the two groups of pushing cylinders 66, and drive the two groups of elastic ropes 68 to stretch. The basalt fiber anchor rods 78 are inserted into the aligned first set of holes and contact the filled concrete. After the two basalt fiber anchor rods 78 are inserted into the first set of holes and in place, the first pressure relief valves on the two sets of first pressure relief pipes 67 are controlled to open, and the pressurized gas accumulated in the head end space of the two sets of pushing cylinders 66 is depressurized and discharged from the two sets of first pressure relief pipes 67. The two sets of pushing seats 69 that have lost the pressurized pressure are quickly reset under the elastic contraction force of the two sets of elastic ropes 68. Similarly, the next set of basalt fiber anchor rods 78 are prepared for insertion, and two basalt fiber anchor rods 78 are inserted into the two holes simultaneously each time. If the spacing between the two groups of pushing cylinders 66 does not match the current spacing between the holes in the tunnel, one of the first three-way valves 61 can be controlled to close to stop the air supply and pressurization, and one of the electric cylinders 74 can be controlled to open to stop the loading of the basalt fiber anchor rod 78, so that the pushing seat 69 in the pushing cylinder 66 loses the pushing effect on the basalt fiber anchor rod 78, and then the pushing cylinder 66 opened by the other group of first three-way valves 61 and the electric cylinder 74 is used to insert a single basalt fiber anchor rod 78 into a single hole through the pushing seat 69, until all the basalt fiber anchor rods 78 are inserted into the holes of the reinforcement layer and reinforced with the filled concrete, thereby completing the comprehensive and stable support work of the reinforcement layer between the high geothermal tunnel and the phase change concrete.
