Description

Technical Field

[0001] This invention relates to the field of tunnel boring machine (TBM) construction technology, and in particular to a TBM spoil disposal system and method. Background Technology

[0002] During tunnel boring machine (TBM) construction, a large amount of excavated soil is generated. This excavated soil needs to be disposed of in a timely manner to avoid environmental pollution and safety hazards. The conventional method for handling excavated soil in the current technology is to directly dump it at a waste disposal site. This method has low transportation efficiency, wastes manpower and resources, and the accumulation of excavated soil at waste disposal sites can easily cause pollution to the surrounding environment.

[0003] Existing research indicates that excavated soil can potentially be used as sand for backfill grouting. Backfill grouting refers to injecting grout behind the shield and segments to fill voids, control ground settlement, plug water, or reinforce the ground. Currently, the grouts used are generally cement-water glass double-liquid grout or cement mortar, which are expensive, and the production of cement and water glass causes significant environmental pollution. If excavated soil could be used for backfill grouting, it would save grouting materials, reduce the use of cement and other materials in the grout, save costs, and be environmentally friendly. It would also solve the drawbacks of traditional excavated soil treatment methods. However, excavated soil cannot be used directly for backfill grouting; it requires modification before use.

[0004] Therefore, there is an urgent need for a shield tunneling spoil disposal system and method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a shield tunneling excavation treatment system and method, which enables the treated excavation to meet the needs of backfill grouting, thereby disposing of the excavation inside the tunnel, reducing the time and resource waste caused by excavation turnover, and also reducing the use of cement and other materials during the grouting process, saving costs and protecting the environment.

[0006] To achieve this objective, the present invention adopts the following technical solution:

In the first position, the transport mechanism avoids the muck output end of the tunnel boring machine. In the second position, one end of the transport mechanism is located directly below the muck output end of the tunnel boring machine, and the other end is located above the muck disposal box. The transport mechanism can transport the muck output from the muck output end of the tunnel boring machine into the muck disposal box.

[0010] A detection unit is installed inside the waste disposal box, and the detection unit is used to detect the remaining amount of waste in the waste disposal box;

[0011] An adding unit is selectively connected to the waste disposal box, and the adding unit is used to add waste disposal agent into the waste disposal box;

[0014] Preferably, the transport mechanism further includes a first roller and a second roller arranged at intervals, the conveyor belt is wound around the first roller and the second roller, and the output end of the first drive member is connected to the first roller or the second roller.

[0015] Preferably, the shield tunneling muck disposal system further includes a mounting frame and a second driving component mounted on the mounting frame. The mounting frame is fixed to the muck disposal box, and the output end of the second driving component is connected to the transport mechanism for driving the transport mechanism to switch between the first position and the second position on the mounting frame.

[0016] Preferably, the transport mechanism further includes a first mounting plate and a second mounting plate, one end of the first roller and the second roller are rotatably connected to the first mounting plate, and the other end of the rollers are rotatably connected to the second mounting plate. The first driving member is fixed on the first mounting plate. The mounting frame is provided with a first guide rail and a second guide rail. The first guide rail and the second guide rail both extend along the transport direction of the conveyor belt. The first mounting plate is slidably connected to the first guide rail, and the second mounting plate is slidably connected to the second guide rail.

[0017] Preferably, a first rotating shaft is coaxially arranged on the first roller, and a second rotating shaft is coaxially arranged on the second roller. One end of the first rotating shaft is connected to the output end of the first driving member, and the other end is rotatably connected to the second mounting plate. One end of the second rotating shaft is rotatably connected to the first mounting plate, and the other end is rotatably connected to the second mounting plate.

[0018] Preferably, the output end of the second drive member is connected to a transmission gear, and a rack is provided on the second mounting plate along its extension direction, wherein the transmission gear meshes with the rack.

[0019] Preferably, the shield tunneling muck disposal system further includes a first connecting pipeline, one end of which is selectively connected to the muck disposal box, and the other end is connected to the synchronous grouting system of the shield machine.

[0020] Preferably, the shield tunneling muck treatment system further includes a second connecting pipeline, one end of which is selectively connected to the muck treatment box, and the other end is connected to the adding unit. A monitoring component is provided on the second connecting pipeline to monitor the amount of muck treatment agent used.

[0021] On the other hand, a method for handling tunnel boring machine (TBM) spoil is provided, employing the TBM spoil handling system described above, including the following steps:

[0022] S1. The detection unit detects the remaining amount of slag in the slag treatment box in real time and determines whether the remaining amount of slag is less than a preset value. If yes, then step S2 is executed; otherwise, step S3 is executed.

[0023] S2. Drive the transport mechanism to the second position so that the excavated soil output from the tunnel boring machine's excavation output end is transported to the excavated soil handling box by the transport mechanism;

[0024] S3. The transport mechanism remains in the first position or is driven back to the first position so that the transport mechanism avoids the muck output end of the tunnel boring machine;

[0025] S4. Start the crushing unit to crush the slag in the slag treatment box;

[0026] S5. Connect the adding unit to the slag treatment box, and add the slag treatment agent into the slag treatment box through the adding unit.

[0027] S6. Start the stirring unit to stir the slag and slag treatment agent in the slag treatment box to form a slurry.

[0028] S7. Connect the slag disposal box to the synchronous grouting system of the tunnel boring machine and carry out grouting operation.

[0029] Beneficial effects:

[0030] The shield tunneling excavation waste disposal system and method provided by this invention, when used on the construction site, uses a detection unit to monitor the remaining amount of excavated waste in the waste disposal box in real time. If the remaining amount is less than a preset value, the transport mechanism is driven to a second position, allowing the excavated waste from the output end to be transported into the waste disposal box until the remaining amount reaches the preset value. At this point, the transport mechanism is driven back to the first position, stopping the transport of excavated waste into the disposal box. Conversely, if the detection unit detects that the remaining amount is greater than or equal to the preset value, the transport mechanism remains in its current position (first position). When processing the excavated waste in the box, the crushing unit is first activated to break the waste into appropriately sized particles (e.g., particles smaller than 5mm). Then, the adding unit is connected to the waste disposal box, and a waste disposal agent is added. Finally, the mixing unit is activated to mix the crushed waste and the waste disposal agent to form a slurry. The addition of the waste disposal agent ensures that the physical and chemical properties of the slurry meet the requirements for backfill grouting. Finally, the slag disposal box is connected to the synchronous grouting system of the tunnel boring machine, so that the synchronous grouting system can extract the grout from the slag disposal box for use in the back wall grouting operation.

[0031] The shield tunneling muck disposal system and method provided by this invention allow for the treatment of muck for use in backfill grouting, saving grouting materials and reducing the use of cement and other materials, thus saving costs and protecting the environment. Simultaneously, the muck can be disposed of inside the tunnel without being dumped at a muck disposal site, reducing the time and resource waste associated with muck turnover. Furthermore, since the transport mechanism can switch between a first position and a second position, when the remaining muck in the muck disposal container meets a preset value, the transport mechanism can return to the first position, thus avoiding the muck output end and not affecting the normal discharge of muck.

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0046] See Figures 1-4 This embodiment provides a shield tunneling excavation waste disposal system, including a waste disposal box 1, a transportation mechanism 2, a detection unit, an addition unit, and a waste disposal mechanism. This system can process the excavation waste generated during the tunnel boring machine's excavation process, ensuring that the processed waste meets the requirements for backfill grouting. This allows for waste disposal within the tunnel, reducing the time and resource waste associated with waste disposal, while also reducing the use of cement and other materials during grouting, saving costs and protecting the environment.

[0047] The waste disposal box 1 can be selectively connected to the synchronous grouting system of the tunnel boring machine (TBM). A transport mechanism 2 is mounted on the waste disposal box 1 and can switch between a first position and a second position. In the first position, the transport mechanism 2 avoids the waste disposal end of the TBM. In the second position, one end of the transport mechanism 2 is directly below the waste disposal end of the TBM, and the other end is above the waste disposal box 1. The transport mechanism 2 can transport the waste disposal material output from the TBM's waste disposal end into the waste disposal box 1. A detection unit is installed inside the waste disposal box 1 to detect the remaining amount of waste disposal material. An adding unit is selectively connected to the waste disposal box 1 and is used to add waste disposal agent to the waste disposal box 1. A waste disposal mechanism is installed inside the waste disposal box 1 and includes a crushing unit and a mixing unit. The crushing unit is configured to crush the waste disposal material in the waste disposal box 1, and the mixing unit can mix the waste disposal material and waste disposal agent in the waste disposal box 1 to form a slurry.

[0048] Optionally, the slag handling mechanism is a mixer, which has a high-speed mode and a low-speed mode. The high-speed mode is used when crushing slag, and the low-speed mode is used when mixing slag. Furthermore, the mixer is connected to the control system of the tunnel boring machine so that the mixer can be remotely controlled through the control system.

[0049] like Figure 1 As shown, a soil conveyor belt 100 is installed below the tunnel boring machine's outlet to receive and transport the excavated soil. The end of the soil conveyor belt 100 furthest from the tunnel boring machine's outlet is the aforementioned soil output end.

[0050] The shield tunneling excavation disposal system and method provided in this embodiment, when used on the construction site, uses a detection unit to monitor the remaining excavation volume in the excavation disposal box 1 in real time. If the remaining excavation volume in the excavation disposal box 1 is less than a preset value, the transport mechanism 2 is driven to the second position, so that the excavation from the excavation output end is transported to the excavation disposal box 1 by the transport mechanism 2 until the remaining excavation volume in the excavation disposal box 1 reaches the preset value. At this point, the transport mechanism 2 is driven back to the first position, stopping the transport of excavation into the excavation disposal box 1. Of course, if the detection unit detects that the remaining excavation volume in the excavation disposal box 1 is greater than or equal to the preset value, the transport mechanism 2 remains in the current position (first position). When processing the excavated soil in the excavation tank, the crushing unit is first activated to break the soil into particles of a suitable size (e.g., particles with a diameter of less than 5mm). Then, the adding unit is connected to the excavated soil processing tank 1, and an excavated soil treatment agent is added to the tank. Next, the mixing unit is activated to mix the crushed soil and the treatment agent to form a slurry. The addition of the treatment agent ensures that the physical and chemical properties of the slurry meet the requirements for backfill grouting. Finally, the excavated soil processing tank 1 is connected to the tunnel boring machine's synchronous grouting system, allowing the system to extract the slurry from the tank for backfill grouting operations.

[0051] The shield tunneling muck disposal system and method provided in this embodiment treat the muck, enabling it to be used for backfill grouting, saving grouting materials and reducing the use of cement and other materials, thus saving costs and protecting the environment. Simultaneously, the muck can be disposed of inside the tunnel without being dumped at a muck disposal site, reducing the time and resource waste associated with muck turnover. Furthermore, since the transport mechanism 2 can switch between a first position and a second position, when the remaining muck in the muck disposal box 1 meets a preset value, the transport mechanism 2 can return to the first position, thus avoiding the muck output end and not affecting the normal discharge of muck.

[0052] The shield tunneling muck disposal system provided in this embodiment has advantages such as integration and miniaturization. It does not affect the quality of the shield tunnel or the operation of the original shield machine during the muck disposal process.

[0053] See Figure 1 and Figure 2Optionally, the transport mechanism 2 includes a first drive unit 21 and a conveyor belt 22. The conveyor belt 22 carries the excavated soil discharged from the tunnel boring machine's (TBM) output end. The output end of the first drive unit 21 is connected to the conveyor belt 22 and drives the conveyor belt 22 to transport the excavated soil to the excavated soil handling box 1. When the transport mechanism 2 reaches the second position, the excavated soil from the TBM's output end falls onto the conveyor belt 22. At this time, after the first drive unit 21 is activated, the excavated soil on the conveyor belt 22 is continuously transported to the excavated soil handling box 1. The conveyor belt 22 has a simple structural design and can continuously transport excavated soil into the excavated soil handling box 1, operating efficiently. Optionally, the first drive unit 21 is a motor. Furthermore, the first drive unit is connected to the TBM's control system, allowing operators to remotely control the start and stop of the first drive unit through the control system.

[0054] Preferably, the transport mechanism 2 further includes a first roller 23 and a second roller 24 spaced apart, with a conveyor belt 22 wound around the first roller 23 and the second roller 24. The output end of the first drive member 21 is connected to the first roller 23 or the second roller 24. With this configuration, starting the first drive member 21 can drive the first roller 23 or the second roller 24 to rotate, thereby causing the conveyor belt 22 wound around the first roller 23 and the second roller 24 to perform a circular motion, so that the slag falling on the conveyor belt 22 can be transported to the slag handling box 1, making transportation convenient.

[0055] Optionally, the shield tunneling muck disposal system also includes a mounting frame and a second drive unit 3 mounted on the mounting frame. The mounting frame is fixed to the muck disposal box 1. (See reference...) Figure 1 The output end of the second drive component 3 is connected to the transport mechanism 2 via a transmission connection, used to drive the transport mechanism 2 to switch between a first position and a second position on the mounting frame. The mounting frame provides stable support for the second drive component 3, and simultaneously supports the transport mechanism 2, facilitating the adjustment of the transport mechanism 2's position by the second drive component 3. The second drive component 3 enables automated adjustment of the transport mechanism 2's position; it can drive the transport mechanism 2 to switch between the first and second positions on the mounting frame, making adjustment convenient. Optionally, the second drive component 3 is a motor. Furthermore, the second drive component 3 is connected to the tunnel boring machine's control system, allowing operators to remotely control the start and stop of the second drive component 3 through the control system.

[0056] In other embodiments, the mounting frame may also be independent of the waste disposal box 1, with the two designed separately, and the mounting frame supported on the side of the waste disposal box 1.

[0057] Optionally, the transport mechanism 2 further includes a first mounting plate 25 and a second mounting plate 26. One end of each of the first roller 23 and the second roller 24 is rotatably connected to the first mounting plate 25, and the other end is rotatably connected to the second mounting plate 26. A first driving member 21 is fixed to the first mounting plate 25. A first guide rail and a second guide rail are provided on the mounting frame. Both the first and second guide rails extend along the transmission direction of the conveyor belt 22. The first mounting plate 25 is slidably connected to the first guide rail, and the second mounting plate 26 is slidably connected to the second guide rail. The first roller 23 and the second roller 24 are connected as a whole by the first mounting plate 25 and the second mounting plate 26, making the transport mechanism 2 stable and compact. The first and second guide rails provide guidance for the transport mechanism 2. By driving the transport mechanism 2 to slide along the first and second guide rails through the second driving member 3, the position of the transport mechanism 2 can be adjusted. At the same time, the first and second guide rails also provide stable support for the transport mechanism 2, ensuring the stability of the connection between the transport mechanism 2 and the mounting frame.

[0058] For example, a first groove is provided on the first guide rail, and a second groove is provided on the second guide rail. Both the first and second grooves extend along the transmission direction of the conveyor belt 22. A first mounting plate 25 is inserted into and slidably engages with the first groove, and a second mounting plate 26 is inserted into and slidably engages with the second groove, thereby achieving a sliding connection between the first mounting plate 25 and the first guide rail, and between the second mounting plate 26 and the second guide rail. Furthermore, the first and second grooves also limit the sliding stroke of the transport mechanism 2, preventing it from detaching from the mounting frame and ensuring the stable operation of the processing system.

[0059] Optionally, a first rotating shaft is coaxially mounted on the first roller 23, and a second rotating shaft is coaxially mounted on the second roller 24. One end of the first rotating shaft is connected to the output end of the first driving member 21, and the other end is rotatably connected to the second mounting plate 26. One end of the second rotating shaft is rotatably connected to the first mounting plate 25, and the other end is rotatably connected to the second mounting plate 26. Further, one end of the first rotating shaft passes through the first mounting plate 25 and is connected to the output end of the first driving member 21. Since the first roller 23 and the second roller 24 cannot be directly rotatably connected to the first mounting plate 25 and the second mounting plate 26, the first rotating shaft and the second rotating shaft are provided, enabling the first roller 23 to be rotatably connected to the first mounting plate 25 and the second mounting plate 26 through the first rotating shaft, and enabling the second roller 24 to be rotatably connected to the first mounting plate 25 and the second mounting plate 26 through the second rotating shaft. The conveyor belt 22 is then wound around the first roller 23 and the second roller 24. The first roller 23 is driven to rotate by the first driving member 21, thereby driving the conveyor belt 22 to make a circular motion, so that the slag falling on the conveyor belt 22 can be transported to the slag disposal box 1 through the conveyor belt 22, which is convenient for transportation.

[0060] In another alternative embodiment, one end of the second rotating shaft may pass through the first mounting plate 25 and be connected to the output end of the first driving member 21, while the other end is rotatably connected to the second mounting plate 26. Correspondingly, one end of the first rotating shaft is rotatably connected to the first mounting plate 25, and the other end is rotatably connected to the second mounting plate 26.

[0061] See Figure 1 , Figure 2 and Figure 4 Furthermore, the output end of the second drive unit 3 is connected to a transmission gear, and a rack 261 is provided on the second mounting plate 26 along its extension direction, with the transmission gear meshing with the rack 261. This arrangement enables the second drive unit 3 and the transport mechanism 2 to achieve a transmission connection through the meshing of the transmission gear and rack 261. When the second drive unit 3 is activated, the circular motion of the transmission gear is converted into the linear reciprocating motion of the rack 261, thereby driving the transport mechanism 2 to slide along the first and second guide rails, thus driving the transport mechanism 2 to switch between the first and second positions on the mounting frame, resulting in high transmission efficiency.

[0062] Furthermore, a gearbox is connected to the output end of the second drive component 3. The gearbox is fixed on the mounting frame, and the transmission gear is located inside the gearbox. The gearbox connects the second drive component 3 to the mounting frame, enabling the second drive component 3 to stably drive the transport mechanism 2 to move on the mounting frame.

[0063] Optionally, the shield tunneling excavation disposal system also includes a first connecting pipeline, one end of which is selectively connected to the excavation disposal box 1, and the other end is connected to the synchronous grouting system of the shield machine. Further, a control valve is installed on the first connecting pipeline to control the on / off state of the pipeline. After excavation disposal is completed, the first control valve is opened to connect the synchronous grouting system to the excavation disposal box 1, and then the synchronous grouting system is driven to extract grout from the excavation disposal box 1 for backfill grouting. Optionally, the first control valve is a solenoid valve, which is communicatively connected to the shield machine's control system, allowing operators to remotely control the on / off state of the first connecting pipeline.

[0064] Optionally, the tunnel boring machine (TBM) spoil disposal system also includes a second connecting pipeline. One end of the second connecting pipeline is selectively connected to the spoil disposal box 1, and the other end is connected to the addition unit. A monitoring component is installed on the second connecting pipeline to monitor the amount of spoil disposal agent used. The monitoring component can monitor the amount of spoil disposal agent used, so that the spoil disposal agent flowing into the spoil disposal box 1 can meet the mixing ratio requirements for forming grouting material.

[0065] Optionally, the monitoring components include a flow meter and a pressure gauge. The flow meter monitors the flow rate of the muck treatment agent, and the pressure gauge monitors the pressure of the muck treatment agent, thereby accurately monitoring the dosage of the muck treatment agent. Furthermore, the monitoring components are connected to the control system of the tunnel boring machine, enabling the data monitored by the components to be fed back to the operator in real time through the control system, allowing the operator to control the dosage of the muck treatment agent.

[0066] Furthermore, the shield tunneling excavation treatment system also includes a third drive unit. The input end of the third drive unit is connected to the adding unit, and one end of the second connecting pipe is connected to the output end of the third drive unit. When the second connecting pipe is connected to the excavation treatment tank 1, the third drive unit is activated to deliver excavation treatment agent into the excavation treatment tank 1. For example, the adding unit is a storage tank, and the excavation treatment agent is stored in the storage tank. The third drive unit is a booster pump. Even further, the third drive unit is connected to the control system of the shield tunneling machine.

[0067] Optionally, a second control valve is installed on the second connecting pipeline to control the on / off state of the second connecting pipeline, which is convenient for control. Optionally, the second control valve is also a solenoid valve, which is communicatively connected to the control system of the tunnel boring machine, so that the operator can remotely control the on / off state of the second connecting pipeline.

[0068] Optionally, the slag treatment agent is a mixture of various components in a certain proportion. Multiple addition units are provided, and the various components of the slag treatment agent are added one-to-one into the slag treatment tank 1 through these multiple addition units. This ensures that the addition of each component does not interfere with each other, and facilitates control over the amount of each component to meet the proportion requirements. In this embodiment, the slag treatment agent is a mixture of a polymer aqueous solution and bentonite slurry in a certain proportion.

[0069] Optionally, the detection unit is connected to the control system of the tunnel boring machine to provide real-time feedback on the remaining amount of excavated soil in the excavated soil handling box 1, enabling operators to monitor it in real time. Optionally, the detection unit is a pressure sensor, which can monitor the quality of the excavated soil in the excavated soil handling box 1 in real time, thus facilitating monitoring.

[0070] In another alternative embodiment, the detection unit can also be a camera, which transmits the image of the slag disposal box 1 to the control system in real time, so that the operator can judge the remaining amount of slag based on the image.

[0071] It should be noted that, due to the varying quality of soil layers within the tunnel, this embodiment only selects gravelly soil, sandy soil, and workable silty soil with a particle size of less than 5mm for recycling, in order to save processing costs and improve the efficiency of spoil disposal. That is, during the tunnel boring machine's excavation process, operators observe and determine whether the excavated soil layers meet the above requirements. If the requirements are met, the tunnel boring machine spoil disposal system provided in this embodiment is activated for recycling.

[0072] In another optional embodiment, the tunnel boring machine (TBM) spoil disposal system may further include a spoil buffer box. Since the required soil layer generally does not penetrate the entire construction process, a spoil buffer box can be set up to buffer the spoil. When the remaining spoil in the spoil disposal box 1 reaches a preset value, the spoil is transported to the spoil buffer box for later use via the transport mechanism 2. Furthermore, a power unit is installed on the spoil buffer box. The spoil buffer box is selectively connected to the spoil disposal box 1. When the TBM is constructing in a tunnel section that does not meet the soil layer requirements and the slurry in the spoil disposal box 1 is insufficient, the spoil buffer box is connected to the spoil disposal box 1, and the power unit transports spoil into the spoil disposal box 1, thereby meeting the material requirements for spoil disposal.

[0073] like Figure 5 As shown, this embodiment also provides a method for handling tunnel boring machine (TBM) spoil, which uses the TBM spoil handling system described above and includes the following steps:

[0074] S1. The detection unit detects the remaining amount of slag in the slag disposal box 1 in real time and determines whether the remaining amount of slag is less than the preset value. If yes, then step S2 is executed; otherwise, step S3 is executed.

[0075] S2. Drive the transport mechanism 2 to the second position so that the excavated soil output from the tunnel boring machine's excavation output end is transported to the excavated soil handling box 1 through the transport mechanism 2;

[0076] S3, the transport mechanism 2 remains in the first position or is driven back to the first position so that the transport mechanism 2 avoids the muck output end of the tunnel boring machine;

[0077] S4. Start the crushing unit to crush the slag and soil in the slag and soil treatment box 1;

[0078] S5. Connect the adding unit to the slag treatment box 1, and add slag treatment agent into the slag treatment box 1 through the adding unit;

[0079] S6. Start the mixing unit to mix the slag and slag treatment agent in the slag treatment box 1 to form a slurry;

[0080] S7. Connect the slag disposal box 1 to the synchronous grouting system of the tunnel boring machine and carry out grouting operations.

[0081] In step S1, the detection unit detects the remaining amount of slag in the slag disposal box 1 in real time and transmits it synchronously to the control system of the tunnel boring machine so that the operator can determine whether it is necessary to transport slag into the slag disposal box 1 based on the remaining amount.

[0082] In step S2, the second drive unit 3 is remotely activated through the control system of the tunnel boring machine to move the transport mechanism 2 to the second position along the first guide rail and the second guide rail. Then, the first drive unit 21 is remotely activated to drive the conveyor belt 22 so that the excavated soil output from the excavated soil output end of the tunnel boring machine is transported to the excavated soil handling box 1 through the conveyor belt 22.

[0083] In step S3, if the detection unit detects that the remaining amount of excavated soil in the excavated soil handling box 1 is less than a preset value, the control system of the tunnel boring machine remotely starts the second drive component to drive the transport mechanism 2 to the second position. Then, the first drive component 21 is started to drive the conveyor belt 22 to rotate, so that the excavated soil at the excavated soil output end is transported to the excavated soil handling box 1 through the transport mechanism 2 until the remaining amount of excavated soil in the excavated soil handling box 1 reaches the preset value. At this time, the first drive component 21 is turned off to stop transporting excavated soil into the excavated soil handling box, and the second drive component 3 is started again to drive the transport mechanism 2 back to the first position. If the detection unit detects that the remaining amount of excavated soil in the excavated soil handling box 1 is greater than or equal to the preset value, the transport mechanism 2 remains in the current position (first position).

[0084] In step S4, the agitator is started and adjusted to high-speed mode through the control system of the tunnel boring machine to crush the slag into particles with a diameter of less than 5mm.

[0085] In step S5, the second control valve is remotely opened through the control system of the tunnel boring machine to connect the adding unit with the slag treatment box 1, and the third drive unit is remotely activated to deliver slag treatment agent into the slag treatment box 1. At the same time, the amount of slag treatment agent is monitored through the monitoring component.

[0086] In step S6, the agitator is adjusted to a low-speed mode by the control system of the tunnel boring machine to mix the slag and slag treatment agent to form a slurry. The operator judges whether the slurry meets the grouting requirements by checking the state of the slurry. If the requirements are met, the agitator is remotely turned off by the control system of the tunnel boring machine to stop mixing.
