Description

Technical Field

[0002] As crucial pathways for penetrating underground space and exploring subterranean resources, vertical shafts have garnered increasing attention in recent years. Currently, vertical shaft construction, both domestically and internationally, primarily utilizes drill-and-blast and mechanical methods. However, as shaft depths continue to increase, the shortcomings of the drill-and-blast method, such as significant disturbance to the surrounding rock, poor construction safety, complex construction procedures, and high ventilation resistance, have become increasingly pronounced, making it increasingly difficult to meet the demands of modern shaft construction. Mechanical rock-breaking technology, particularly full-face shaft boring machines (TBMs), will become the future trend and development direction for shaft construction, thanks to their high-quality, efficient excavation, and safe and reliable performance.

[0003] In the technology of full-section vertical shaft boring machines, the reception of the boring machines is a very important step, which is of great significance for protecting equipment, improving construction progress and the overall coherence and coordination of the project. At present, the reception methods of vertical shaft boring machines vary according to different construction processes, which mainly include upper dismantling method and lower dismantling method. For large-diameter vertical shafts with existing tunnels at the bottom, the use of a combined construction method of "raised well drilling rig pilot well + lower slag discharge and hole expansion type vertical shaft boring machine" has become a future development trend, but this construction method puts higher requirements on the reception process of the vertical shaft boring machine. In response to this problem, although a variety of dismantling methods have been proposed in the existing technology, they all require the use of special equipment to lift the vertical shaft boring machine for dismantling operations. When the vertical shaft is deep, there are problems of poor dismantling safety and low dismantling efficiency.

[0088] Implementation Method 1

[0089] like Figures 1 to 19As shown, the present invention provides a receiving device for dismantling a shaft boring machine, which includes a receiving and transporting device 1 and a plurality of supporting devices 2. The receiving and transporting device 1 is used to be movably arranged in an existing tunnel 20 below a shaft 10. The receiving and transporting device 1 has a lifting base 101 and a receiving plate 102 for receiving the shaft boring machine 30. The receiving plate 102 is detachably arranged on the top of the lifting base 101. The top of the receiving plate 102 has an accommodating recess. The accommodating recess is filled with material blocks 103; multiple supporting devices 2 are located in the existing tunnel 20, and the supporting devices 2 have at least a movable supporting end 211. When the cutter head 3001 of the shaft boring machine 30 is received in the accommodating recess, the multiple supporting devices 2 are distributed at intervals along the circumference of the shaft boring machine 30, and the supporting ends 211 of the multiple supporting devices 2 respectively support the main machine 3002 of the shaft boring machine 30, so that the main machine 3002 is supported in a suspended position through the cooperation of the multiple supporting devices 2.

[0090] In the present invention, during the excavation of the vertical shaft 10, a movable receiving and transporting device 1 can be set in the existing tunnel 20 below the vertical shaft 10, and a plurality of supporting devices 2 can be set in the existing tunnel 20. When the vertical shaft boring machine 30 is received, the cutter head 3001 of the vertical shaft boring machine 30 can be received by the receiving plate 102 of the receiving and transporting device 1, and the main machine 3002 of the vertical shaft boring machine 30 can be supported and positioned by cooperating with the plurality of supporting devices 2. Then, the cutter head 3001 and the main machine 3002 can be disassembled, and the cutter head 3001 can be independently transported out by the receiving and transporting device 1. Afterwards , the receiving and transporting device 1 can be returned to its original position to receive the main machine 3002, and cooperate with multiple supporting devices 2 to disassemble and transport the main machine 3002 in sections, and finally complete the disassembly operation of the shaft boring machine 30. In this process, the cutter head 3001 is stably received by the reaming shaft boring machine disassembly receiving device 60, and the main machine 3002 is received and transported in sections, which can ensure that the shaft boring machine 30 is safely and stably docked at the preset position in the existing tunnel 20, providing reliable support and working space for disassembly, transportation and other operations, effectively improving the disassembly efficiency and ensuring the safety of the disassembly personnel.

[0091] In an optional embodiment of the present invention, the material block 103 may be, but is not limited to, a concrete block. It is necessary to ensure that the hardness of the material block 103 is the same as or close to the hardness of the rock mass excavated by the shaft boring machine 30 . During the receiving process of the cutterhead 3001, since the material block 103 is filled in the accommodating recess of the receiving plate 102, and the hardness of the material block 103 is ensured to be the same as or close to the hardness of the rock mass excavated by the shaft boring machine 30, the cutterhead 3001 of the shaft boring machine 30 can be ensured to be in a stable and continuously stressed state when the cutterhead 3001 of the shaft boring machine 30 is excavating the last section of the shaft 10 (at this time, at least part of the cutterhead 3001 has entered the existing tunnel 20 and connected with the material block or has cut the material block), thereby avoiding the deviation of the shaft boring machine 30, thereby not only ensuring the smooth completion of the excavation of the shaft 10, but also ensuring the stable recovery of the shaft boring machine 30 and ensuring the safety of the recovery operation of the shaft boring machine 30.

[0092] In an optional embodiment of the present invention, the inner wall of the receiving recess has the same shape as the excavation surface of the cutterhead 3001, and the top surface of the material block 103 is flush with the plane of the top opening of the receiving recess. During the actual receiving process, the height of the receiving tray 102 in the receiving and transporting device 1 must be adjusted until the top surface of the material block 103 is tightly aligned with the top inner wall of the existing tunnel 20, ensuring stable reception of the shaft boring machine 30 in the initial state.

[0093] In this embodiment, if Figure 1 、 Figure 13 and Figure 14 As shown, the accommodating recess can be a conical groove with a radius gradually decreasing from top to bottom, so that the accommodating recess can stably accommodate the cutter disc 3001 to ensure stable accommodation and transportation after the cutter disc 3001 is disassembled, thereby improving the safety of the recovery of the cutter disc 3001.

[0094] In an optional embodiment of the present invention, Figure 1 As shown, the lifting base 101 includes a bottom plate 1011, a top plate 1012, and a plurality of lifting cylinders 1013. The bottom plate 1011 and the top plate 1012 are both arranged in the horizontal direction. The top plate 1012 is located above the bottom plate 1011. The bottom of the receiving tray 102 is detachably connected to the top of the top plate 1012. The plurality of lifting cylinders 1013 are evenly arranged between the top plate 1012 and the bottom plate 1011. The cylinder body of each lifting cylinder 1013 is respectively fixed to the top of the bottom plate 1011. The piston rod of each lifting cylinder 1013 extends vertically and is respectively fixedly connected to the bottom of the top plate 1012. Therefore, the lifting cylinders 1013 can push the top plate 1012 up and down to adjust the vertical position of the receiving tray 102, thereby achieving the receiving and external transportation of the cutterhead 3001. The lifting cylinders 1013 can be, but are not limited to, oil cylinders.

[0095] In an optional embodiment of the present invention, Figure 1 As shown, a slag drop hole 10121 is formed vertically through the top plate 1012 in the middle of the top plate 1012. A slag drop channel 1021 is formed vertically through the receiving plate 102 within the receiving plate 102. The slag drop channel 1021 is vertically connected to the slag drop hole 10121. Rock blocks, rock debris, etc. generated during the excavation process can fall through the slag drop channel 1021 and the slag drop hole 10121 into the existing roadway 20, achieving slag discharge.

[0096] In an optional embodiment of the present invention, Figure 1 and Figure 2 As shown, the cylinder body of the lifting cylinder 1013 is fixed to the top of the bottom plate 1011, and the piston rod of the lifting cylinder 1013 extends vertically. A position adjustment member 1015 is provided between the end of the piston rod and the bottom of the top plate 1012. The position adjustment member 1015 is used to slide and adjust the relative position between the piston rod and the top plate 1012. The provision of the position adjustment member 1015 can achieve the function of axial force transmission, which can not only ensure that the piston rod of the lifting cylinder 1013 can provide a stable axial force (i.e., a vertical upward supporting force) to the receiving plate 102, but also allow a small range of horizontal displacement between the piston rod of the lifting cylinder 1013 and the top plate 1012, thereby preventing the lifting cylinder 1013 from being subjected to tangential force due to the rotation of the cutter disc 3001 during the receiving process of the cutter disc 3001, ensuring the stable support of the lifting cylinder 1013 for the receiving plate 102, and extending the service life of the lifting cylinder 1013.

[0097] Specifically, such as Figure 2 As shown, the position adjustment member 1015 includes a first block-shaped connecting member 10151 and a second plate-shaped connecting member 10152. The bottom of the first connecting member 10151 is connected to the end of the piston rod of the lifting cylinder 1013, and the top of the second connecting member 10152 is connected to the bottom of the top plate 1012. The top surface of the first connecting member 10151 has a groove 10153 with an arc-shaped cross section, and the bottom surface of the second connecting member 10152 has a protrusion 10154 with an arc-shaped cross section. The protrusion 10154 can be slidably embedded in the groove 10153, and the protrusion 10154 can be slidably embedded in the groove 10153. There is a gap between 154 and the groove 10153, so that the protrusion 10154 has a certain amount of movement in the groove 10153. Through the cooperation between the protrusion 10154 and the groove 10153, it is ensured that the first connecting member 10151 and the second connecting member 10152 can adaptively adjust the angle between the two, and the horizontal position between the first connecting member 10151 and the second connecting member 10152 can be adjusted, thereby ensuring that the piston rod of the lifting cylinder 1013 can provide a stable axial force to the receiving plate 102, avoiding the influence of the tangential force on the lifting cylinder 1013.

[0098] Further, such as Figure 2 As shown, an annular boss 10155 is formed on the side wall of the first connecting member 10151, and the bottom of the second connecting member 10152 has an annular hook 10156 extending downward, and the bottom of the hook 10156 has a hook portion 10157 bent inward, and the hook portion 10157 is clamped on the bottom of the boss 10155, and ensures that there is a certain amount of sliding between the hook portion 10157 and the boss 10155. The setting of the hook portion 10157 and the boss 10155 only serves to limit the first connecting member 10151 and the second connecting member 10152 and prevent the two from separating, but will not affect the adjustment of the position between the first connecting member 10151 and the second connecting member 10152.

[0099] In an optional embodiment of the present invention, Figure 1 As shown, a rigid telescopic sleeve 1014 is sleeved around the outer periphery of the lifting cylinder 1013. The ends of the rigid telescopic sleeve 1014 are connected to the bottom of the top plate 1012 and the top of the bottom plate 1011, respectively. The rigid telescopic sleeve 1014 expands and contracts with the height of the top plate 1012. During the operation of the shaft boring machine 30, the tangential force generated on the piston rod of the lifting cylinder 1013 by the rotation of the cutterhead 3001 is entirely borne by the rigid telescopic sleeve 1014.

[0100] In an optional embodiment of the present invention, Figure 1 As shown, a plurality of first rollers 1016 are provided at the bottom of the bottom plate 1011 to realize the transport function of the receiving and transporting device 1 after receiving the cutter head 3001 or part of the main machine 3002. Of course, a transport trolley can also be directly provided at the bottom of the receiving and transporting device 1 to realize the function of mobile transportation.

[0101] In an optional embodiment of the present invention, Figure 3 and Figure 4As shown, the supporting device 2 includes a first supporting cylinder 201 and a second supporting cylinder 202. The cylinder body of the second supporting cylinder 202 is located below the cylinder body of the first supporting cylinder 201, and the cylinder body of the first supporting cylinder 201 is hinged to the first anti-sliding block 203, and the cylinder body of the second supporting cylinder 202 is hinged to the second anti-sliding block 204. The first anti-sliding block 203 and the second anti-sliding block 204 are respectively fixedly embedded in the rock mass of the inner wall of the existing tunnel 20, and the end of the piston rod of the first supporting cylinder 201 is connected to the piston rod of the second supporting cylinder 202. The ends of the supporting devices 2 are hinged, and a supporting block 205 (i.e., the supporting end 211 of the supporting device 2) is provided at the location where the piston rod of the first supporting cylinder 201 and the piston rod of the second supporting cylinder 202 are hinged. During the process of supporting the main machine 3002 of the shaft boring machine 30, the position of the supporting block 205 is adjusted by adjusting the extension length of the piston rod of the first supporting cylinder 201 and / or the piston rod of the second supporting cylinder 202, so that the supporting block 205 supports the main machine 3002 of the shaft boring machine 30. The supporting blocks 205 of multiple supporting devices 2 cooperate to ensure that the main machine 3002 is supported in a stable suspended state, thereby enabling the cutterhead 3001 to be disassembled and transported. In addition, by adjusting the extension length of the piston rods of different first supporting cylinders 201 and / or different second supporting cylinders 202, the posture of the main machine 3002 in the supported state can be adjusted. It should be noted that the first supporting cylinder 201 and the second supporting cylinder 202 in a supporting device 2 are staggered in the vertical direction, that is, the axes of the first supporting cylinder 201 and the second supporting cylinder 202 are not in the same plane, so that when the first supporting cylinder 201 and the second supporting cylinder 202 are hinged, the actions of the first supporting cylinder 201 and the second supporting cylinder 202 will not interfere with each other.

[0102] In the present invention, the first supporting cylinder 201 and the second supporting cylinder 202 may be, but are not limited to, oil cylinders.

[0103] In another optional embodiment of the present invention, Figure 5 and Figure 6 As shown, the supporting device 2 includes a support frame 206, and the bottom of the support frame 206 has a second roller 207. When the shaft boring machine 30 is to be received, the support frame 206 moves to the bottom of the shaft boring machine 30, and the top crossbeam of the support frame 206 supports the main machine 3002 of the shaft boring machine 30. When the main machine 3002 does not need to be supported, the support frame 206 can be moved to a position close to the inner wall of the expansion chamber 40 to avoid affecting the normal lowering of the shaft boring machine 30. The specific structure of the support frame 206 is not specifically limited here. The top of the support frame 206 has a crossbeam (i.e., the supporting end 211 of the supporting device 2) that can stably support the main machine 3002, and it is sufficient to ensure that the support frame 206 is sufficiently stable.

[0104] In another optional embodiment of the present invention, Figure 7 and Figure 8 As shown, the supporting device 2 includes a vertically arranged upright pole 208 having at least one fixing hole 2081. The bottom of the upright pole 208 is fixed to the bottom rock of the existing tunnel 20. A fastener is disposed in the fixing hole 2081 to secure the upright pole 208 to the inner wall rock of the existing tunnel 20. A horizontally retractable connecting rod 209 (i.e., a supporting end 211 of the supporting device 2) is disposed at the top of the upright pole 208. A third supporting cylinder 210 is disposed between the connecting rod 209 and the outer wall of the upright pole 208. The cylinder body of the third supporting cylinder 210 is hinged to the outer wall of the upright pole 208, and the end of the piston rod of the third supporting cylinder 210 is hinged to the outer wall of the connecting rod 209 to drive the connecting rod 209 to retract and retract. When the connecting rod 209 is extended, it can support the main body 3002 of the shaft boring machine 30. The fastener may be, but is not limited to, a bolt or a locking pin. The connecting rod 209 can move passively with the extension and retraction of the piston rod of the third supporting cylinder 210. When it is necessary to bear the weight of the shaft boring machine 30, the piston rod of the third supporting cylinder 210 is controlled to extend to drive the connecting rod 209 to extend into place, and then the piston rod of the third supporting cylinder 210 is locked, thereby playing a temporary supporting role. When there is no need to support the main machine 3002, the piston rod of the third supporting cylinder 210 can be retracted, that is, the connecting rod 209 is retracted, so that it will not affect the normal lowering of the shaft boring machine 30.

[0105] In the present invention, the third supporting cylinder 210 may be, but is not limited to, an oil cylinder.

[0106] In an optional embodiment of the present invention, multiple grippers are spaced apart along the circumference of the main machine 3002. The main machine 3002 and the grippers are connected by retractable guide posts. During excavation of the shaft 10, the grippers can be pressed against the inner wall of the shaft 10 to ensure stable excavation of the shaft boring machine 30. During dismantling and recovery, the supporting end 211 of the supporting device 2 can be pressed against the bottom of the main machine 3002 and the guide posts to provide stable support for the main machine 3002.

[0107] The features and advantages of the disassembly receiving device 60 for a shaft boring machine of the present invention are:

[0108] 1. The receiving device 60 for dismantling a shaft boring machine, through the cooperation of the receiving and transporting device 1 and the plurality of supporting devices 2, can stably receive the cutterhead 3001 of the shaft boring machine 30 and receive and transport the main engine 3002 of the shaft boring machine 30 in sections. This ensures that the shaft boring machine 30 is safely and stably docked at a preset position within the existing tunnel 20, provides reliable support and working space for dismantling and transportation operations, effectively improves dismantling efficiency, and ensures the safety of dismantling personnel.

[0109] Second, the receiving device 60 for dismantling a shaft boring machine, by filling the receiving recess of the receiving plate 102 with a material block 103, can ensure that the cutterhead 3001 of the shaft boring machine 30 remains in a stable and continuously stressed state when excavating the final section of the shaft 10, thereby preventing the shaft boring machine 30 from deflecting. This not only ensures the smooth completion of excavation of the shaft 10, but also ensures the stable recovery of the shaft boring machine 30, thereby ensuring the safety of the shaft boring machine 30 recovery operation.

[0110] Implementation Method 2

[0111] like Figures 1 to 20 As shown, the present invention provides a method for receiving a tunnel boring machine, which at least uses the above-mentioned device for receiving and disassembling a shaft boring machine to disassemble and recycle the shaft boring machine 30. The tunnel boring machine receiving method includes:

[0112] Step S1: installing a plurality of supporting devices 2 in the existing tunnel 20 below the shaft 10;

[0113] Specifically, such as Figures 3 to 8 、 Figure 10 and Figure 20 As shown, when the shaft boring machine 30 has advanced downward to a vertical distance of approximately 10 meters from the existing tunnel 20 (i.e., a predetermined distance), the shaft boring machine 30 can be paused to remove fallen rock blocks, rock debris, etc. from the existing tunnel 20. Subsequently, multiple supporting devices 2 are installed in the expansion chamber 40 to prepare for supporting the main unit 3002 of the shaft boring machine 30.

[0114] Step S2: Installing a receiving and transporting device 1 in the existing tunnel 20 at a position opposite to the shaft 10;

[0115] Specifically, in step S2, as Figure 11 and Figure 20 As shown, the track 50 can be extended into the expansion cavern 40 , and the receiving and transporting device 1 can be moved from the existing tunnel 20 through the track 50 to directly below the cutterhead 3001 of the shaft boring machine 30 ;

[0116] Step S3: When the shaft boring machine 30 is in a suspended state, the height of the lifting base 101 in the receiving and transporting device 1 is adjusted until the top surface of the material block 103 in the receiving and transporting device 1 contacts the top inner wall of the existing tunnel 20;

[0117] Specifically, such as Figure 12 and Figure 20As shown, when the receiving and transporting device 1 is in place, the lifting cylinder 1013 in the lifting base 101 can be controlled to push the receiving plate 102 upward, and the rigid telescopic sleeve 1014 is extended synchronously with the piston rod of the lifting cylinder 1013 until the top surface of the material block 103 is tightly fitted with the top inner wall of the existing tunnel 20. At this time, the lifting cylinder 1013 can be locked, and the top surface of the material block 103 has a dome shape that can be adapted to the top inner wall of the existing tunnel 20, thereby ensuring that the top surface of the material block 103 can be tightly fitted with the top inner wall of the existing tunnel 20, so as to ensure that the shaft boring machine 30 can be stably received in the initial state.

[0118] Step S4: The shaft boring machine 30 continues to excavate until the shaft 10 intersects the existing tunnel 20. In step S4, after entering the existing tunnel 20, the cutterhead 3001 of the shaft boring machine 30 cuts at least a portion of the material block 103 in the receiving tray 102 of the receiving and transporting device 1, so that the cutterhead 3001 is received in the receiving tray 102.

[0119] Specifically, such as Figure 13 and Figure 20 As shown, before the shaft boring machine 30 resumes its excavation state after pausing, its excavation parameters can be adjusted, controlling the cutterhead 3001 to reduce its rotational speed and rock-breaking efficiency, and continuing to excavate the final section of the shaft 10 using low thrust and low torque until the shaft 10 is fully connected to the existing roadway 20. At this point, the cutterhead 3001 has entered the receiving plate 102 and removed most of the material blocks 103. The arrangement of the material blocks 103 ensures that the cutterhead 3001 is subjected to steady and continuous force during the final excavation phase. Rock blocks and rock debris generated during excavation fall through the slag channel 1021 and slag hole 10121 into the existing roadway 20, achieving slag removal. During excavation, the lifting base 101 provides vertical support for the shaft boring machine 30, preventing it from falling during the dismantling process due to the underlying rock mass being unable to support the weight of the shaft boring machine 30. Among them, a position adjustment part 1015 is arranged between the piston rod of the lifting cylinder 1013 and the top plate 1012. The setting of the position adjustment part 1015 can realize the function of axial force transmission, which can not only ensure that the piston rod of the lifting cylinder 1013 can provide a stable axial force (i.e., vertical upward supporting force) to the receiving plate 102, but also allow a small range of horizontal displacement between the piston rod of the lifting cylinder 1013 and the top plate 1012 to avoid the lifting cylinder 1013 being subjected to tangential force due to the rotation of the cutter disc 3001 during the receiving process of the cutter disc 3001, thereby ensuring the stable support of the lifting cylinder 1013 for the receiving plate 102, and the tangential force generated by the rotation of the cutter disc 3001 is borne entirely by the rigid telescopic sleeve 1014.

[0120] Step S5: Multiple supporting devices 2 respectively support the main machine 3002 of the shaft boring machine 30 to place the shaft boring machine 30 in a suspended position;

[0121] Specifically, such as Figure 14 、 Figure 15 and Figure 20 As shown, the grippers on the main machine 3002 can then be controlled to retract and separate from the inner wall of the shaft 10, and the lifting base 101 can be slowly lowered until the stroke of the lifting cylinder 1013 is close to zero. At this point, the cutterhead 3001 is completely inserted into the existing tunnel 20. At this point, the shaft boring machine 30 can be controlled to stop, and the side blocks of the cutterhead 3001 can be removed using a hand hoist. The removed side blocks are then transported out through the existing tunnel 20. The supporting ends 211 of each supporting device 2 are then controlled to extend toward the main machine 3002 and respectively support the bottom of the guide column connected to each gripper. The posture of the main machine 3002 can then be flexibly adjusted by adjusting the position of the supporting ends 211 of the supporting devices 2.

[0122] Step S6: disassembling the cutter head 3001 and the main machine 3002, and transporting the cutter head 3001 out through the receiving and transporting device 1;

[0123] Specifically, such as Figure 16 and Figure 20 As shown, the connection part between the cutter disc 3001 and the main machine 3002 can then be disassembled to separate the cutter disc 3001 from the main machine 3002, and the piston rod of the lifting cylinder 1013 can be slowly retracted until the stroke is zero. At this time, the cutter disc 3001 is completely separated from the main machine 3002, and the weight of the cutter disc 3001 is entirely borne by the receiving and moving device 1, while the weight of the main machine 3002 is borne by multiple supporting devices 2.

[0124] Step S7: removing the receiving tray 102 from the lifting base 101;

[0125] Specifically, the cutter disc 3001 and the receiving and transporting device 1 can be transported out of the existing tunnel 20 along the track 50. After the cutter disc 3001 is transported out, the connection between the receiving plate 102 and the lifting base 101 can be removed.

[0126] Step S8: Move the lifting base 101 back to a position in the existing tunnel 20 opposite the shaft 10, and raise the lifting base 101 until the bottom of the mainframe 3002 contacts the top of the lifting base 101. At this time, the supporting devices 2 for the mainframe 3002 can be released.

[0127] Step S9: Lowering the height of the lifting base 101 until at least part of the mainframe 3002 enters the existing tunnel 20, and the plurality of supporting devices 2 respectively support the mainframe 3002 again, and disassembling the portion of the mainframe 3002 below the supporting position;

[0128] Specifically, such as Figure 17 、 Figure 18 and Figure 20 As shown, the lifting base 101 with the receiving plate 102 removed is returned along the track 50 to the bottom of the main machine 3002, and the piston rod of the lifting cylinder 1013 is controlled to extend so that the top of the top plate 1012 is supported on the bottom of the main machine 3002. Subsequently, the supporting ends 211 of the multiple supporting devices 2 are retracted, and the weight of the main machine 3002 is entirely borne by the lifting base 101; then the piston rod of the lifting cylinder 1013 is contracted a little, causing the main machine 3002 to slowly descend. After reaching the predetermined position (ensuring that the bottom of the main machine 3002 enters the existing lane 20), the supporting position of the multiple supporting devices 2 on the main machine 3002 is adjusted upward and the supporting ends 211 of the multiple supporting devices 2 are used to support the main machine 3002 again. At this time, the multiple supporting devices 2 replace the lifting base 101 to bear the entire weight of the main machine 3002. Thereafter, the part of the main machine 3002 located below the multiple supporting devices 2 can be disassembled.

[0129] Step S10: Figure 19 and Figure 20 As shown, the disassembled main machine 3002 is partially transported out by the lifting base 101, and steps S9 to S10 are repeated until the main machine 3002 is completely disassembled and transported out, completing the disassembly operation of the shaft boring machine 30.

[0130] In an optional embodiment of the present invention, Figure 9 、 Figure 20 As shown, before step S1, the existing tunnel 20 can be expanded at its rear end using a drilling and blasting method, thereby forming an expansion chamber 40 in the existing tunnel 20 at a position opposite the shaft 10, into which the shaft boring machine 30 can be lowered and disassembled. Subsequently, a track 50 extending to the expansion chamber 40 can be laid in the existing tunnel 20 to accommodate the movement of the transport device 1 along the track 50. In the early stages, the track 50 is laid only to the outside of the expansion chamber 40, and does not extend into the expansion chamber 40, to prevent the track 50 from being damaged by rocks, debris, etc. that fall during the excavation of the shaft boring machine 30.

[0131] The characteristics and advantages of the roadheader receiving method of the present invention are:

[0132] This tunnel boring machine receiving method does not require the use of special equipment to constantly lift the shaft tunnel boring machine 30 for dismantling operations, thus avoiding abnormal shaking of the tunnel boring machine caused by disturbance of the wire rope during the lifting process, and largely ensuring the safety of the dismantling, and is therefore suitable for dismantling operations in deep shafts; at the same time, this method fully utilizes the transportation properties and spatial conditions of the existing tunnel 20, provides workers with a good working environment, and greatly improves the dismantling efficiency.

[0133] The tunnel boring machine receiving method of the present invention has the same characteristics and advantages as the above-mentioned reaming shaft tunnel boring machine disassembly receiving device 60, which will not be described in detail here.
