Description

Technical Field

[0001] This application relates to the field of subway construction technology, and in particular to a construction method for a tunnel boring machine to move, lift, and push through a station structure. Background Technology

[0002] Tunnel boring machines (TBMs), as key equipment in underground tunnel construction, are widely used in infrastructure construction fields such as subways and water conservancy projects. During tunnel construction, after completing the excavation of a section, the TBM often needs to move to a new construction location to continue operations; this movement is commonly referred to as TBM relocation. TBM relocation technology directly affects construction efficiency and project costs, thus becoming a key focus of the industry.

[0003] Currently, the method of horizontally moving, lifting, and pushing the tunnel boring machine (TBM) across the station is relatively common among existing technologies. The conventional operating procedure is as follows: First, construction personnel securely fix the support frame to the TBM to ensure its overall stability during movement. Next, steel plates are laid on the ground to create the basic track for the TBM's movement. Then, grease is applied to the contact surfaces between the support frame and the steel plates to reduce friction and movement resistance. Finally, with the help of pulley systems or external jacks, the TBM is gradually pushed to complete the horizontal movement across the station. This method has been widely used in practical engineering and, to a certain extent, meets the needs of TBMs crossing stations.

[0004] Regarding the aforementioned technologies, the inventors believe that laying steel plates on the ground not only increases the initial construction costs but also takes too long, affecting the construction period. Summary of the Invention

[0005] The purpose of this application is to provide a construction method for a tunnel boring machine to move, lift, and push the station structure through the air, so as to improve the problem that laying steel plates on the ground not only increases the early construction cost but also takes too long and affects the construction period.

[0006] This application provides a construction method for a tunnel boring machine (TBM) to be moved, lifted, and pushed through a station structure, which adopts the following technical solution:

[0007] A tunnel boring machine (TBM) translation, jacking, and air-pushing station structure includes a base frame. The TBM body is placed on the base frame along its length. Positioning plates are installed on both sides of the TBM body along its length, with the plates inclined and tangent to the outer walls of the TBM body. At least one set of translation drive components is symmetrically arranged on both sides of the TBM body on the base frame. Several reaction supports are installed on the outer walls of the TBM body corresponding to the translation drive components, and the reaction supports are fixedly connected to the output ends of the translation drive components. Several jacking brackets are installed on the outer walls of the TBM body along the width of the base frame. Several jacking drive components are installed on both sides of the base frame corresponding to the jacking brackets, and the output ends of the jacking drive components are fixedly connected to the bottom surfaces of the jacking brackets. Several layers of pads are installed below the base frame, including a main pad located directly below the base frame and auxiliary pads located on both sides of the main pad corresponding to the jacking drive components.

[0008] By adopting the above technical solutions, and by setting the positioning plate to be tangent to the outer wall of the shield machine body, precise positioning and guidance can be achieved, which helps to ensure the stable movement of the shield machine during the movement process and improve the stability of the station crossing. The alternation of translation and jacking can effectively reduce the friction between the shield machine and the ground, reduce the requirements on the ground, eliminate the need to lay steel plates, shorten the construction time, and improve the efficiency of the station crossing. At the same time, the height of the base frame can be adjusted by stacking the base plates to adapt to the needs of different construction sites.

[0009] Optionally, the base frame includes several long plates arranged along the length of the main body of the tunnel boring machine, and several wide plates are spaced apart on the top surface of the long plates along the width of the base frame; several buffer grooves are provided on the top surface of the wide plates, buffer pressure cylinders are provided in the buffer grooves, buffer elastic elements are provided in the buffer grooves, and placement plates are fixedly provided at the output ends of several buffer pressure cylinders.

[0010] By adopting the above technical solutions, the underframe uses a combination of long and wide plates, which helps to enhance the overall load-bearing capacity. The buffer grooves, buffer pressure cylinders, and buffer elastic elements set on the wide plates can alleviate and absorb the vibration and impact generated during the placement and movement of the tunnel boring machine, protect the main structure of the tunnel boring machine, extend the service life of the equipment, and reduce equipment damage and maintenance costs caused by vibration. The placement plate provides a stable bearing surface for the tunnel boring machine, which helps to place it stably.

[0011] Optionally, a rotating seat is provided on the bottom surface of the placement plate within the wide plate interval. A connecting rotating plate is rotatably provided on the rotating seat. A sliding plate that slides within the wide plate interval is rotatably provided on the end of the connecting rotating plate away from the rotating seat. Sliding grooves are provided on both sides of the wide plate. Sliding blocks are correspondingly provided on both sides of the sliding plate. When the main body of the tunnel boring machine is placed on the placement plate, the sliding blocks abut against one end of the sliding groove.

[0012] By adopting the above technical solution, when the main body of the tunnel boring machine is placed on the placement plate, the placement plate will press downward under its gravity. During this process, the connecting rotating plate rotates around the rotating seat, thereby driving the sliding plate to slide in the groove of the wide plate until the sliding plate stops moving when it comes into contact with one end of the groove. The movement of the mechanical structure decomposes and absorbs the gravitational impact of the tunnel boring machine. Compared with traditional rigid support, it can more effectively reduce the impact of the impact force on the main body of the tunnel boring machine and the entire station structure, reduce the damage to the internal precision components of the tunnel boring machine caused by excessive instantaneous impact force, protect the core structure of the equipment, and extend the service life of the equipment.

[0013] Optionally, a booster hydraulic cylinder is provided in the chute along its length, the booster hydraulic cylinder is connected to the buffer hydraulic cylinder, and the output end of the booster hydraulic cylinder is fixed to the side of the slider opposite to its direction of movement.

[0014] By adopting the above technical solution, when the main body of the tunnel boring machine is placed on the placement plate, the buffer hydraulic cylinder contracts under the action of gravity, and inputs hydraulic oil into the boost hydraulic cylinder connected to it. The potential energy generated by the downward pressure of the tunnel boring machine is converted into the hydraulic energy of the boost hydraulic cylinder, realizing the recovery and reuse of energy. This allows the boost hydraulic cylinder to push the slide plate, making the slide plate move more smoothly and reducing the possibility of jamming.

[0015] Optionally, a fixing plate is provided at the end of the skateboard away from the placement plate. The fixing plate is fixedly connected to the outer wall of the wide plate and the positioning plate to stabilize the skateboard. The translation drive component is located on the fixing plate.

[0016] By adopting the above technical solution, the fixed plate connects and fixes the slide plate, the wide plate and the locking plate, which enhances the stability of the slide plate and helps the translation drive to exert force stably during operation. The translation drive is installed on the fixed plate, making the entire drive structure layout compact and reasonable, easy to install and maintain, and improving the linkage of the structure.

[0017] Optionally, the long plate is slidably provided with a push plate along its length direction, the bottom surface of the push plate is provided with a plurality of sliding seats corresponding to the long plate, the placement plate is located on both sides of the push plate, and the top surface of the push plate is provided with an elastic pad for the shield machine body to be placed.

[0018] By adopting the above technical solution, the push plate and the long plate slide together, and the top surface of the push plate is provided with an elastic pad to provide additional support and buffer for the shield machine body. This helps to increase the friction between the push plate and the shield machine body, enabling them to move synchronously. In addition, it disperses the weight of the shield machine and reduces the pressure on the placement plate.

[0019] Optionally, the wide plate is inclined and provided with several auxiliary support plates to cooperate with the positioning plate to form a triangular stable structure, and the top surface of the positioning plate is provided with a sliding strip that abuts and is tangent to the outer wall of the shield machine body along its length.

[0020] By adopting the above technical solution, the auxiliary support plate on the wide plate and the positioning plate form a triangular stable structure, which greatly enhances the support strength and stability of the tunnel boring machine and helps the main body of the tunnel boring machine to move smoothly. The sliding strip on the top surface of the positioning plate can reduce the friction between the tunnel boring machine and the positioning plate, making the tunnel boring machine move more easily, reducing energy consumption and equipment wear, and extending its service life.

[0021] Optionally, the pad includes a plurality of long and short pads arranged in a crisscross pattern, and the long and short pads of the secondary pad are arranged more densely than the long and short pads of the primary pad.

[0022] By adopting the above technical solution, the long and short pads in the pad plate are arranged in a crisscross pattern, which can better distribute the weight of the tunnel boring machine and the underframe, and improve the load-bearing capacity and stability of the pad plate; in particular, the dense arrangement of the auxiliary pads can effectively support the lifting drive components, ensure that the tunnel boring machine is stable and reliable during the lifting process, reduce tilting or collapse caused by insufficient load-bearing capacity of the pad plate, and improve construction safety.

[0023] Another objective of this application is to provide a construction method for a tunnel boring machine (TBM) to move, lift, and push through a station structure, employing the following technical solution:

[0024] S100: The main body of the tunnel boring machine is moved and placed on the placement plate and the push plate, while the outer side wall of the main body of the tunnel boring machine is tangent to the top surface of the positioning plate;

[0025] S200: Fix the fixing plate to the end of the slide away from the placement plate, and fix the fixing plate to the outer wall of the wide plate and the positioning plate and install the fixed translation drive component. Install the reaction support on the outer wall of the shield machine body corresponding to the translation drive component and fix it to the output end of the translation drive component. Install the lifting bracket and the lifting drive component.

[0026] S300: Start the translation drive. After the shield machine body moves along the length of the underframe, the translation drive stops after 80% of its stroke. Simultaneously start several lifting drives to lift the shield machine body and underframe. After checking the level of the lifting drives, start the translation drive to move the underframe along its length. The lifting drives retract their output ends and lower the shield machine body, and the underframe is placed on the ground.

[0027] S400: The loop step S300 continues.

[0028] By adopting the above technical solution, this construction method has a clear sequence of steps: first, the tunnel boring machine (TBM) is positioned; then, the drive components are installed and fixed; and finally, the TBM is pushed through the station by alternating translation and jacking. The construction process is clear and easy for construction personnel to understand and execute. The alternation of translation and jacking can effectively reduce the friction between the TBM and the ground, reduce the requirements for the ground, eliminate the need to lay steel plates, shorten the construction time, and improve the efficiency of passing through the station.

[0029] Optional, including:

[0030] S500: Simultaneously activate several jacking drive components to lift the main body of the tunnel boring machine along with the underframe, place the main pad under the underframe, and simultaneously retract the jacking drive components to place the underframe on the main pad; continue to retract the jacking drive components to lift them off the ground, place the auxiliary pad at the same height as the main pad under the jacking drive components, and control the jacking drive components to resist the auxiliary pad to maintain stability.

[0031] S600: Cyclic step S500 continuously lifts the main body of the tunnel boring machine.

[0032] By adopting the above technical solution, several jacking drive components are simultaneously activated to lift the main body of the tunnel boring machine (TBM) along with its underframe, ensuring uniform force distribution during the jacking process. During the placement of the main and auxiliary pads, the retraction of the jacking drive components is precisely controlled to ensure the underframe is stably placed on the pads, and the jacking drive components and auxiliary pads are stably in contact, providing a reliable guarantee for the safe lifting of the TBM and reducing safety risks during construction. The jacking height of the TBM is controlled by cyclically executing the S500 steps. This step-by-step, cyclical operation method allows for more precise adjustment of the TBM height, meeting the precise height requirements of different construction scenarios. It is suitable for projects with high construction precision requirements, improving the accuracy and quality of construction.

[0033] In summary, this application includes at least one of the following beneficial technical effects of the construction method for the tunnel boring machine (TBM) to move, lift, and push through the station structure:

[0034] 1. By setting the positioning plate tangent to the outer wall of the tunnel boring machine (TBM), precise positioning and guidance can be achieved, which helps to ensure the stable movement of the TBM during the movement process and improves the stability of the TBM when passing through the station. The alternating translation and jacking can effectively reduce the friction between the TBM and the ground, reduce the requirements for the ground, eliminate the need to lay steel plates, shorten the construction time, and improve the efficiency of passing through the station. At the same time, the height of the underframe can be adjusted by stacking the pads to adapt to the needs of different construction sites.

[0035] 2. When the main body of the tunnel boring machine is placed on the placement plate, the placement plate presses downward under its gravity. During this process, the connecting rotating plate rotates around the rotating seat, thereby driving the sliding plate to slide in the groove of the wide plate until the sliding plate stops moving when it comes into contact with one end of the groove. The movement of the mechanical structure decomposes and absorbs the gravitational impact of the tunnel boring machine. Compared with traditional rigid support, it can more effectively reduce the impact of the impact force on the main body of the tunnel boring machine and the entire station structure, reduce the damage to the internal precision components of the tunnel boring machine caused by excessive instantaneous impact force, protect the core structure of the equipment, and extend the service life of the equipment.

[0036] 3. The push plate slides with the long plate, and the top surface of the push plate is equipped with an elastic pad to provide additional support and cushioning for the shield machine body. This helps to increase the friction between the push plate and the shield machine body, enabling them to move synchronously. In addition, it disperses the weight of the shield machine and reduces the pressure on the placement plate. Attached Figure Description

The base frame 1, as the fundamental load-bearing component of the entire structure, consists of several long plates 11 arranged along the length of the TBM body 2. Several wide plates 12 are spaced apart on the top surface of the long plates 11 along the width of the base frame 1. Both the long plates 11 and the wide plates 12 are made of metal, and the wide plates 12 are welded to the long plates 11 to form a stable grid structure, enhancing the load-bearing capacity of the base frame 1.

[0047] Reference Figure 1 , Figure 2 The base frame 1 has positioning plates 3 installed on both sides of the shield machine body 2 along its length. The positioning plates 3 are fixed to the long plate 11 by welding and are inclined. The inclination angle is designed according to the outer contour of the shield machine body 2 and is tangent to the outer wall of the shield machine body 2, serving to limit and guide movement. The wide plate 12 is inclined with several auxiliary support plates 31, the specific number of which is not limited. The auxiliary support plates 31 are connected to the wide plate 12 and the positioning plates 3 by welding, forming a triangular stable structure with the positioning plates 3 to enhance the support stability of the shield machine body 2. The top surface of the positioning plate 3 is provided with a sliding strip 32 along its length, which abuts against and is tangent to the outer wall of the shield machine body 2. The sliding strip 32 is fixed to the top surface of the positioning plate 3 by bolts. The sliding strip 32 is made of polished wear-resistant metal material, which can reduce the friction when the shield machine body 2 moves.

[0048] Reference Figure 1 , Figure 2 At least one set of translation drive components 4 are symmetrically arranged on both sides of the shield machine body 2 on the base frame 1. In this embodiment, two sets of four are preferred. The translation drive components 4 are hydraulic jacks. The two sets of translation drive components 4 are arranged in opposite directions but are driven synchronously through a hydraulic control system. That is, when one set of translation drive components 4 extends, the other set of translation drive components 4 assists in retraction, and the driving directions are the same. A fixing plate 41 is provided at the end of the slide plate 65 away from the placement plate 62. The fixing plate 41 is connected to the slide plate 65 by welding. At the same time, the fixing plate 41 is fixedly connected to the wide plate 12 and the outer wall of the positioning plate 3 by welding to further stabilize the slide plate 65. The translation drive components 4 are fixedly installed on the fixing plate 41 by bolts.

[0049] Reference Figure 1 , Figure 2The outer wall of the shield machine body 2 is provided with several reaction supports 21 corresponding to the translation drive component 4. The reaction supports 21 are fixed to the outer wall of the shield machine body 2 by welding. The reaction supports 21 are fixed to the output end of the translation drive component 4 by bolts. The outer wall of the shield machine body 2 is provided with several lifting brackets 22 along the width direction of the base frame 1. The lifting brackets 22 are fixed to the outer wall of the shield machine body 2 by welding. The base frame 1 is provided with several lifting drive components 23 corresponding to the lifting brackets 22 on both sides. The lifting drive components 23 are also hydraulic jacks. Their output ends are fixed to the bottom surface of the lifting brackets 22 by bolts.

[0050] Reference Figure 2 , Figure 3 Several layers of pads 5 are provided under the base frame 1. The pads 5 are used to adjust the height of the base frame 1 and enhance stability. The pads 5 include a main pad 51 located directly below the base frame 1 and auxiliary pads 52 located on both sides of the main pad 51 corresponding to the lifting drive component 23. The pads 5 include several long pads 53 and short pads 54 arranged in a crisscross pattern. The long pads 53 and short pads 54 are fixed to the pads 5 by welding to form a grid-like support structure. The long pads 53 and short pads 54 of the auxiliary pads 52 are arranged more densely than the long pads 53 and short pads 54 of the main pads 51 to meet the load-bearing requirements of the lifting drive component 23.

[0051] Reference Figure 4 A push plate 7 is slidably mounted on the long plate 11 along its length. Several sliding blocks 71 are correspondingly mounted on the bottom surface of the push plate 7. The sliding blocks 71 and the push plate 7 are an integral structure. The sliding blocks 71 and the long plate 11 are slidably engaged to allow the push plate 7 to slide on the long plate 11. Placement plates 62 are located on both sides of the push plate 7. Elastic pads 72, made of rubber, are mounted on the top surface of the push plate 7 and fixed to the top surface of the push plate 7 with countersunk bolts, providing cushioning and anti-slip properties for the shield machine body 2 to be placed on.

[0052] Reference Figure 5 , Figure 6 The top surface of the wide plate 12 is provided with several buffer grooves 121, which are groove structures formed by milling on the top surface of the wide plate 12. A buffer pressure cylinder 6 is installed inside the buffer groove 121, and the buffer pressure cylinder 6 is fixedly installed at the bottom of the buffer groove 121 by bolts, with its output end vertically upward. Simultaneously, a buffer elastic element 61 is also provided inside the buffer groove 121. The buffer elastic element 61 is preferably a compression spring, which is sleeved on the outside of the cylinder of the buffer pressure cylinder 6, with one end welded to the bottom of the buffer groove 121 and the other end welded and fixed to the bottom surface of the placement plate 62. The placement plate 62 is fixedly installed at the output end of the several buffer pressure cylinders 6, and the placement plate 62 is welded to the output end of the buffer pressure cylinder 6, for directly supporting the shield machine body 2.

[0053] Reference Figure 5 , Figure 6A rotating seat 63 is provided on the bottom surface of the placement plate 62 within the interval of the wide plates 12. The rotating seat 63 is fixedly installed on the bottom surface of the placement plate 62 by bolts and has a bearing inside. The connecting rotating plate 64 is rotatably connected to the rotating seat 63 through the bearing, allowing the connecting rotating plate 64 to rotate freely around the central axis of the rotating seat 63. A sliding plate 65 is rotatably provided at the end of the connecting rotating plate 64 away from the rotating seat 63, and slides 65 are located within the interval of the wide plates 12. The sliding plate 65 is rotatably connected to the connecting rotating plate 64 by a pin, and sliders 651 are provided on both sides of the sliding plate 65. The sliders 651 and the sliding plate 65 are integral structures. The wide plate 12 has grooves 122 on both sides of the sliding plate 65. The grooves 122 are grooves machined into the side of the wide plate 12.

[0054] Reference Figure 5 , Figure 6 A booster hydraulic cylinder 1221 is installed along the length of the slide groove 122. The booster hydraulic cylinder 1221 is fixedly installed at one end of the slide groove 122 by bolts, and the booster hydraulic cylinder 1221 is connected to the buffer hydraulic cylinder 6 through a hydraulic pipeline to realize the linkage control of the hydraulic system. The slider 651 abuts against one end of the slide groove 122, and the output end of the booster hydraulic cylinder 1221 is fixed to the side of the slider 651 opposite to its direction of movement by welding. When the shield machine body 2 is placed on the placement plate 62, the buffer hydraulic cylinder 6 absorbs the gravity of the shield machine body 2 during the return stroke and causes the booster hydraulic cylinder 1221 to push the slide plate 65 to slide in the slide groove 122 through the oil circuit.

[0055] The implementation principle of this application embodiment is as follows:

[0056] In actual use, during the translation process, the shield machine body 2 is first moved onto the placement plate 62 and the push plate 7, and the positioning is completed using the limiting and guiding function of the positioning plate 3. At this time, the sliders 651 on both sides of the sliding plate 65 abut against one end of the sliding groove 122 of the wide plate 12, and the booster hydraulic cylinder 1221 is connected to the buffer hydraulic cylinder 6 to buffer the pressure of the shield machine body 2. The translation drive 4 is started, and its output end pushes the reaction support 21, thereby driving the shield machine body 2 to move along the length direction of the base frame 1. It stops when it reaches 80% of the stroke of the translation drive 4. Then, the lifting drive 23 is started simultaneously, and its output end lifts the shield machine body 2 along with the base frame 1. The translation drive 4 is started again. At this time, since the base frame 1 has been lifted, the friction with the ground is reduced, and the translation drive 4 drives the base frame 1 to move. After the machine is moved into position, the lifting drive component 23 retracts, lowering the shield machine body 2 and placing the base frame 1 stably on the ground, completing one translation operation. By continuously repeating this process, the shield machine body 2 can be continuously translated. There is no need to lay steel plates, which shortens the construction time and improves the efficiency of passing through stations.

[0057] During the lifting process, several lifting drive components 23 are activated simultaneously, their output ends extending to lift the main body 2 of the tunnel boring machine (TBM) along with the underframe 1. Once the underframe 1 is lifted to a certain height, a main pad 51 is placed below it, providing initial support and adjusting its height. Subsequently, the lifting drive components 23 retract, allowing the underframe 1 to rest stably on the main pad 51. The lifting drive components 23 continue to retract until their output ends are off the ground. At this point, a secondary pad 52 of the same height as the main pad 51 is placed below the lifting drive components 23, controlling the lifting drive components 23 to abut against the secondary pad 52 to ensure stable support for the entire structure. By continuously repeating the above operation, the number of pad layers 5 is gradually increased, achieving continuous lifting of the main body 2 of the TBM until the required height is reached.

[0060] S100: The shield machine body 2 is transported and placed on the placement plate 62 and the push plate 7 by hoisting equipment. During the placement process, ensure that the outer wall of the shield machine body 2 is tangent to the top surface of the positioning plate 3, and use the positioning plate 3 to perform preliminary positioning of the shield machine body 2.

[0061] S200: Fix the fixing plate 41 to the end of the slide plate 65 away from the placement plate 62 by welding. At the same time, fix the fixing plate 41 to the outer wall of the wide plate 12 and the positioning plate 3 to enhance the stability of the slide plate 65. Then install and fix the translation drive component 4. Install the reaction support 21 on the outer wall of the shield machine body 2 corresponding to the translation drive component 4 and fix it to the output end of the translation drive component 4 by bolts. At the same time, install the lifting bracket 22 and the lifting drive component 23 to complete the connection and assembly of the translation and lifting structure.

[0062] S300: Start the translation drive 4. The shield machine body 2 moves along the length of the base frame 1 under the push of the translation drive 4. When it has traveled to 80% of the stroke of the translation drive 4, the translation drive 4 stops. Simultaneously start several lifting drive 23. The output end of the lifting drive 23 extends to lift the shield machine body 2 and the base frame 1. Check the level of the lifting drive 23 with tools such as a level. After ensuring that the shield machine body 2 is in a horizontal position, start the translation drive 4 again to move the base frame 1 along its length. After moving into position, the lifting drive 23 retracts its output end and lowers the shield machine body 2, so that the base frame 1 is placed stably on the ground.

[0063] S400: Repeat step S300 continuously to achieve continuous translation of the main body 2 of the tunnel boring machine.

[0064] Reference Figure 1 , Figure 2 When the tunnel boring machine needs to be lifted:

[0065] S500: Simultaneously activate several lifting drive components 23. The output ends of the lifting drive components 23 extend to lift the shield machine body 2 along with the base frame 1. After the base frame 1 is lifted to a certain height, place the main pad 51 under the base frame 1. After the main pad 51 is in place, the lifting drive components 23 retract synchronously, so that the base frame 1 is placed stably on the main pad 51. Continue to retract the lifting drive components 23 until the output ends of the lifting drive components 23 are off the ground. Place the auxiliary pad 52 at the same height as the main pad 51 under the lifting drive components 23, and control the lifting drive components 23 to abut against the auxiliary pad 52 to ensure the stable support of the entire structure.

[0066] S600: Repeat step S500 continuously to raise the main body 2 of the tunnel boring machine to the required height. The implementation principle of Embodiment 2 of this application is the same as that of Embodiment 1.
