Description

Technical Field

[0001] This application relates to the field of tunnel construction technology, and in particular to a grouting device and tunnel boring equipment. Background Technology

[0002] During tunnel construction, after the tunnel boring machine detaches from the tunnel lining segments, an over-excavated gap will appear on the back of the segments because the excavation diameter is larger than the outer diameter of the segments. To avoid ground subsidence or collapse, the gaps need to be filled with grout after the segments are installed to ensure project quality and safety.

[0003] In existing technologies, grouting devices are typically used to fill the voids on the back of tunnel segments. These devices usually include a grouting pump, a grouting pipe, and a pressure monitoring device. The grouting pump provides the grout pressure, the grouting pipe delivers the grout into the voids for filling, and the pressure monitoring device monitors the grouting pressure and controls the amount of grout injected by the pump and pipe.

[0004] However, current grouting devices are prone to over-grouting or under-grouting, resulting in poor grouting effect. Summary of the Invention

[0005] This application provides a grouting device and tunnel excavation equipment to solve the problem that current grouting devices are prone to over-grouting or under-grouting, resulting in poor grouting effect.

[0006] To achieve the above objectives, the technical solution of this application is as follows:

The grouting device includes: an equipment platform extending axially along a track; a slewing mechanism movable along the extension direction of the equipment platform and rotatable relative to the equipment platform; a drilling mechanism disposed on the slewing mechanism and configured to perform drilling operations on the tunnel wall to form a grouting space; a grouting mechanism, at least a portion of which is disposed on the slewing mechanism for grouting within the grouting space; a geological monitoring device disposed on the slewing mechanism for monitoring gaps on the tunnel wall; and a control module disposed on the equipment platform and communicatively connected to the geological monitoring device, the slewing mechanism, the drilling mechanism, and the grouting mechanism, respectively. The control module controls the operation of the slewing mechanism, the drilling mechanism, and the grouting mechanism based on the monitoring results of the geological monitoring device.

[0008] In one possible implementation, the grouting device provided in this application includes a drilling mechanism comprising: a push rod, telescopically mounted on a rotary mechanism; a drill bit, detachably mounted on the push rod; and a first driving device, which is connected to the drill bit via the push rod to drive the drill bit to perform drilling operations.

[0009] In one possible implementation, the grouting device provided in this application includes: a liquid supply device disposed on an equipment platform; a grouting pipe, at least a portion of which is disposed on a rotary mechanism, for injecting grout into the grouting space; a liquid injection drive device disposed between the liquid supply device and the grouting pipe, for driving the grout in the liquid supply device to flow to the grouting pipe; and a telescopic support frame telescopically disposed on the rotary mechanism.

[0010] In one possible implementation, the grouting device provided in this application has a grouting nozzle at the end of the grouting pipe away from the liquid injection drive device.

[0011] In one possible implementation, the grouting device provided in this application includes a first liquid supply device and a second liquid supply device, wherein the first liquid supply device stores a first grout and the second liquid supply device stores a second grout; the grouting drive device includes a first grouting drive device and a second grouting drive device; the grouting mechanism further includes a mixing pipe having a first inlet, a second inlet and an outlet, wherein the first liquid supply device, the first grouting drive device and the first inlet are sequentially connected to form a first grouting branch; the second liquid supply device, the second grouting drive device and the second inlet are sequentially connected to form a second grouting branch; and the outlet is connected to the inlet of the grouting pipe.

[0012] In one possible implementation, the grouting device provided in this application has a one-way valve on the upstream side of at least one of the first inlet and the second inlet.

[0013] In one possible implementation, the grouting device provided in this application further includes: a first injection control console, disposed between the first injection drive device and the first inlet, the first injection control console being used to regulate the injection conditions of the first injection branch; and a second injection control console, disposed between the second injection drive device and the second inlet, the second injection control console being used to control the injection conditions of the second injection branch.

[0014] In one possible implementation, the grouting device provided in this application has a platform with a moving track extending along the axial direction of the tunnel; the rotary mechanism includes: a rotary table, which is movable along the moving track and rotatable relative to the platform; a rotary drive device, which is connected to the rotary table to drive the rotary table to rotate; and a translation drive device, which is located on the platform and connected to the rotary table to drive the rotary table to move along the moving track.

[0015] In one possible implementation, the grouting device provided in this application includes a rotary table comprising a first section and a second section distributed sequentially along the tunnel axis, the first section being located on the side of the second section facing the equipment platform; a drilling mechanism being located on the second section; and an observation platform being provided on the first section for observing the grouting status.

[0016] On the other hand, this application provides a tunnel boring machine including the above-mentioned grouting device.

[0017] The grouting device and tunnel boring equipment provided in this application include a rotary mechanism that is movable along the extension direction of the equipment platform and rotatable relative to the platform. The rotary mechanism houses a drilling mechanism and a grouting mechanism, enabling full coverage of any point on the tunnel lining segments. When the geological monitoring device detects a gap between the tunnel lining segment and the tunnel wall, the location signal requiring drilling and grouting is transmitted to the rotary and drilling mechanisms via a control module. The rotary mechanism then moves the drilling mechanism to the gap to perform drilling operations. Subsequently, the rotary mechanism moves the grouting mechanism to the drilling location to perform grouting operations. During the grouting process, the grouting mechanism automatically controls the grouting operation based on the grouting pressure. Simultaneously, the geological monitoring device monitors and analyzes the gap in real time. Once the gap is detected as filled with grout, the control module stops the grouting operation. Therefore, by setting up a geological monitoring device and a control module, the location of the gap and whether grouting at the gap is complete can be accurately determined, avoiding over-grouting or under-grouting and improving the grouting effect.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the preferred embodiments of this application will be described in more detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0049] It should be noted that in the description of the embodiments of this application, the terms "upper", "lower", "inner", "outer" and other terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description, and do not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0050] Furthermore, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0051] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0052] During tunnel construction, after the tunnel boring machine detaches from the tunnel lining segments, an over-excavated gap will appear on the back of the segments because the excavation diameter is larger than the outer diameter of the segments. To avoid ground subsidence or collapse, the gaps need to be filled with grout after the segments are installed to ensure project quality and safety.

[0053] In existing technologies, grouting devices are typically used to fill the voids on the back of tunnel segments. These devices usually include a grouting pump, a grouting pipe, and a pressure monitoring device. The grouting pump provides the grout pressure, the grouting pipe delivers the grout into the voids for filling, and the pressure monitoring device monitors the grouting pressure and controls the amount of grout injected by the pump and pipe.

[0054] However, current grouting devices cannot determine whether grouting is needed based on the stratum. At the same time, the accuracy of judging whether the voids have been filled by only monitoring the grouting pressure with pressure monitoring devices is low, which can easily lead to over-grouting or under-grouting, resulting in poor grouting effect.

[0055] In view of this, the grouting device and tunnel boring equipment provided in this application include a rotary mechanism that is movable along the extension direction of the equipment platform and rotatable relative to the equipment platform. The rotary mechanism is equipped with a drilling mechanism and a grouting mechanism. Through the rotary mechanism, the drilling mechanism and the grouting mechanism can achieve full coverage of any point on the tunnel segment. When the geological monitoring device detects a gap between the tunnel segment and the tunnel wall, the location signal for the required drilling and grouting is transmitted to the rotary mechanism and the drilling mechanism via the control module. The rotary mechanism drives the drilling mechanism to move to the gap to perform drilling operations. Then, the rotary mechanism drives the grouting mechanism to move to the drilling location to perform grouting operations. During the grouting operation, the grouting mechanism can automatically control the grouting operation according to the grouting pressure. Simultaneously, the geological monitoring device monitors and analyzes the gap in real time. When the gap is detected as completely filled with grout, the control module can control the grouting mechanism to stop the grouting operation. Therefore, by setting up a geological monitoring device and a control module, the gap location and whether the gap has been completely filled with grout can be accurately determined, avoiding over-grouting or under-grouting, thus improving the grouting effect.

[0056] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0057] On the one hand, see Figures 1 to 6 This application provides a grouting device 10 for tunnel boring equipment. The grouting device 10 includes: an equipment platform 100 extending axially along a track; a slewing mechanism 200 movable along the extension direction of the equipment platform 100 and rotatable relative to the equipment platform 100; a drilling mechanism 300 disposed on the slewing mechanism 200 and configured to perform drilling operations on the tunnel wall to form a grouting space; and a grouting mechanism 400, at least a portion of which has a structure... A rotary mechanism 200 is installed to inject grout into the grouting space; a geological monitoring device 500 is installed on the rotary mechanism 200 and is used to monitor the gaps on the tunnel wall; a control module is installed on the equipment platform 100 and is communicatively connected to the geological monitoring device 500, the rotary mechanism 200, the drilling mechanism 300, and the grouting mechanism 400 respectively. The control module controls the operation of the rotary mechanism 200, the drilling mechanism 300, and the grouting mechanism 400 according to the monitoring results of the geological monitoring device 500.

[0058] In this application, the equipment platform 100 serves as the foundation of the entire grouting device 10. The equipment platform 100 extends along the track axis, providing stable support to other structures within the grouting device 10, thus ensuring the continuity and stability of the grouting device 10 during tunnel excavation.

[0059] It should be noted that the rotary mechanism 200 is movable along the extension direction of the equipment platform 100 and can rotate relative to the equipment platform 100, thus expanding the coverage area of ​​drilling and grouting operations. By setting up the rotary mechanism 200, drilling and grouting operations can be accurately directed to any point on each ring of tunnel segments. Compared to manually dragging the grouting device, this improves the accuracy of aligning the grouting point, while also increasing construction precision and efficiency. Furthermore, the mobility of the rotary mechanism 200 facilitates rapid adjustments during tunnel excavation to cope with complex and changing geological conditions.

[0060] It is understandable that the rotary mechanism 200 is equipped with a drilling mechanism 300. The movement and rotation of the rotary mechanism 200 drive the drilling mechanism 300 to move and rotate, so that the drilling mechanism 300 is precisely aligned with the drilling point. Then, through the drilling operation of the drilling mechanism 300, a grouting space is formed on the tunnel wall.

[0061] Furthermore, the rotary mechanism 200 is also equipped with a grouting mechanism 400. When the drilling mechanism 300 completes the drilling operation, the rotary mechanism 200, through its own movement and rotation, drives the grouting mechanism 400 to move and rotate, so that the grouting mechanism 400 is precisely aligned with the borehole, and then grout is injected into the borehole to fill the gap between the tunnel segments and the tunnel wall. In this way, through the cooperation between the rotary mechanism 200, the drilling mechanism 300, and the grouting mechanism 400, drilling and grouting operations are efficiently achieved.

[0062] In practice, to ensure the accuracy of drilling and grouting operations, a geological monitoring device 500 and a control module (not shown in the figure) are installed on the rotary mechanism 200. During tunnel excavation, the geological monitoring device 500 monitors the geological conditions in real time. When the geological monitoring device 500 detects a gap between the tunnel lining segments and the tunnel wall, the location signal for drilling and grouting is transmitted to the rotary mechanism 200 and the drilling mechanism 300 via the control module. Then, the drilling mechanism 300, driven by the rotary mechanism 200, precisely moves to the drilling location to perform the drilling operation. After the drilling operation is completed, the rotary mechanism 200... The grouting mechanism 400 moves to the borehole to perform grouting operations. During the grouting operation, the grouting mechanism 400 can automatically control the grouting operation according to the grouting pressure. At the same time, the geological monitoring device 500 monitors and analyzes the gaps in real time. When the gap is detected to be filled by grouting, the grouting mechanism 400 can be controlled to stop the grouting operation through the control module to ensure the grouting effect. Thus, by setting up the geological monitoring device 500 and the control module, the influence of the grouting volume on the segment posture can be better controlled, the disturbance of the grouting operation to the strata can be reduced, the grouting effect can be improved, and adverse construction hazards such as roof collapse caused by grouting can be avoided.

[0063] See Figure 1 and Figure 2 In this embodiment of the application, the drilling mechanism 300 includes: a push rod 310, which is telescopically mounted on the rotary mechanism 200; a drill bit 320, which is detachably mounted on the push rod 310; and a first driving device 330, which is connected to the drill bit 320 via the push rod 310 to drive the drill bit 320 to perform drilling operations.

[0064] It should be noted that the push rod 310 is designed to be telescopic, with its fixed end securely mounted on the rotary mechanism 200. This allows the telescopic end of the push rod 310 to be flexibly and precisely adjusted according to the actual distance from the tunnel wall and the required drilling depth. By precisely controlling the telescopic length of the push rod 310, it can be ensured that the drill bit 320 accurately reaches the drilling point, thus ensuring the smooth progress of subsequent drilling operations.

[0065] Furthermore, the drill bit 320, connected to the push rod 310, is the direct tool for drilling operations. The drill bit 320 features a detachable design, facilitating its replacement and maintenance, and allowing the drilling mechanism 300 to flexibly select different specifications of drill bits 320 according to varying geological conditions and drilling requirements. Specifically, the drill bit 320 can be an anchor drilling rig, a pneumatic drill, etc., but this embodiment does not impose any limitations.

[0066] To drive the drill bit 320 for efficient drilling operations, the drilling mechanism 300 is also equipped with a first drive device 330. The first drive device 330 is connected to the push rod 310 for transmission, thereby transmitting power to the drill bit 320.

[0067] In practice, the geological monitoring device 500 monitors the geological conditions in real time. If a gap is detected, the geological monitoring device 500 locates the gap and transmits an alarm signal to the drilling mechanism 300 and the rotary mechanism 200 through the control module. After receiving the signal, the drilling mechanism 300 moves to the gap position (i.e., the drilling point) driven by the rotary mechanism 200. During the drilling operation, the first drive device 330 drives the push rod 310 to extend and drives the drill bit 320 to perform the drilling operation.

[0068] It is understood that the first drive device 330 can automatically adjust its output power and rotation speed according to changes in parameters such as drilling depth and formation hardness to ensure that the drill bit 320 can successfully complete the drilling operation. Specifically, the first drive device 330 can use a power source such as an electric motor or a hydraulic motor to drive the extension and retraction of the push rod 310 and the high-speed rotation of the drill bit 320; this embodiment does not impose any limitations on this.

[0069] See Figure 2 In this embodiment, the grouting mechanism 400 includes: a liquid supply device 410 disposed on the equipment platform 100; a grouting pipe 420, at least a portion of which is disposed on the rotary mechanism 200, for injecting grout into the grouting space; a liquid injection drive device 430 disposed between the liquid supply device 410 and the grouting pipe 420, for driving the grout in the liquid supply device 410 to flow to the grouting pipe 420; and a telescopic support frame 480 telescopically disposed on the rotary mechanism 200.

[0070] The liquid supply device 410 is installed on the equipment platform 100. The liquid supply device 410 is used to store and prepare the grout required for grouting, ensuring the quality and stability of the grout supply. The liquid supply device 410 may be equipped with a stirring mechanism to maintain the uniformity of the grout and avoid sedimentation, stratification or coagulation of the grout, thereby ensuring the consistency and reliability of the grouting effect.

[0071] Furthermore, the grouting pipe 420 serves as a grout transfer pipe, and at least a portion of the grouting pipe 420 is arranged within the rotary mechanism 200. This allows the grouting operation to be flexibly adjusted with the movement of the rotary mechanism 200, achieving full coverage of complex grouting spaces.

[0072] A grouting drive device 430 is installed between the grouting supply device 410 and the grouting pipe 420. The grouting drive device 430, through its internal power conversion mechanism, pushes the grout in the grouting supply device 410 towards the grouting pipe 420 at a stable and controllable flow rate. The grouting drive device 430 can employ a pumping principle, utilizing mechanical or hydraulic energy as a power source to ensure that the grout maintains sufficient pressure and flow rate during transmission to meet the needs of the grouting operation.

[0073] See Figure 1 and Figure 5 In this embodiment of the application, a grouting nozzle 440 is also provided at the end of the grouting pipe 420 that is away from the liquid injection drive device 430.

[0074] In practice, to facilitate grouting operations, the grouting pipe 420 is connected to a grouting nozzle 440. This allows for more controllable grouting results as the grout flows out of the grouting pipe 420 and into the grouting space. Simultaneously, the grouting mechanism 400 also incorporates a telescopic support frame 480 to guide the grouting nozzle 440 to the grouting port for grouting operations, thereby improving the grouting accuracy of the nozzle 440.

[0075] During the grouting operation, the grouting nozzle 440 ensures that the grout is ejected at appropriate pressure and flow rate, and evenly and stably covers the grouting space. This improves the density and uniformity of the grout, thereby enhancing the grouting effect.

[0076] In addition, the grouting nozzle 440 is easy to maintain and replace. During prolonged use or in special circumstances, workers can easily inspect and replace the grouting nozzle 440 to ensure the continuous stability and reliability of the grouting operation.

[0077] See Figure 1 and Figure 3 In this embodiment, the liquid supply device 410 includes a first liquid supply device 411 and a second liquid supply device 412. The first liquid supply device 411 stores a first slurry, and the second liquid supply device 412 stores a second slurry. The liquid injection drive device 430 includes a first liquid injection drive device 431 and a second liquid injection drive device 432. The grouting mechanism 400 also includes a mixing pipe 450, which has a first inlet, a second inlet, and an outlet. The first liquid supply device 411, the first liquid injection drive device 431, and the first inlet are sequentially connected to form a first liquid injection branch. The second liquid supply device 412, the second liquid injection drive device 432, and the second inlet are sequentially connected to form a second liquid injection branch. The outlet is connected to the inlet of the grouting pipe 420.

[0078] In this application, the liquid supply device 410 is divided into a first liquid supply device 411 and a second liquid supply device 412. The first liquid supply device 411 and the second liquid supply device 412 are independent liquid supply units that store first slurry and second slurry with different properties or compositions. In this way, the grouting operation can flexibly select or mix the first slurry and the second slurry according to the specific engineering requirements, thereby achieving a better grouting effect.

[0079] To ensure the smooth flow of the first and second slurries to the grouting pipe 420, the slurry driving device 430 is also configured as a first slurry driving device 431 and a second slurry driving device 432. The first slurry driving device 431 and the second slurry driving device 432 are respectively responsible for providing power to the slurries in the first slurry supply device 411 and the second slurry supply device 412, ensuring that the first and second slurries can be delivered into the grouting pipe 420 at a predetermined flow rate and pressure.

[0080] Furthermore, to achieve the mixing of the first and second slurries, the grouting mechanism 400 also includes a mixing pipe 450. The mixing pipe 450 has a first inlet, a second inlet, and an outlet, corresponding to the connection point of the first and second injection branches and the inlet of the grouting pipe 420, respectively. The first injection branch is formed by sequentially connecting the first supply device 411, the first injection drive device 431, and the first inlet of the mixing pipe 450, ensuring that the first slurry can smoothly enter the mixing pipe 450. Similarly, the second injection branch is formed by sequentially connecting the second supply device 412, the second injection drive device 432, and the second inlet of the mixing pipe 450, allowing the second slurry to also smoothly enter the mixing pipe.

[0081] Inside the mixing pipe 450, the first and second slurries are thoroughly mixed during flow to form the desired mixed slurry. Subsequently, the mixed slurry is fed into the grouting pipe 420 through the outlet of the mixing pipe 450, and then injected into the gap via the grouting nozzle 440, ultimately completing the grouting operation. This allows for flexible selection and mixing of the slurry, improving the efficiency and accuracy of the grouting operation.

[0082] It should be noted that the fixed end of the telescopic support frame 480 is fixedly connected to the rotary mechanism 200, and the telescopic end is connected to the mixing liquid pipe 450. The telescopic support frame 480 drives the mixing liquid pipe 450 to extend or retract from the rotary mechanism 200 through the extension and retraction of the telescopic end, thereby driving the grouting nozzle 440 to reach the grouting port for grouting operation.

[0083] After the grouting operation is completed, the telescopic support frame 480 begins to retract so that the grouting nozzle 440 leaves the grouting port. At this time, the rotary mechanism 200 drives the drilling mechanism 300 to move to this position, and then the drill bit 320 is replaced with a plug to seal the grouting port. At the same time, the grouting mechanism 400 (e.g., the grouting pipe 420) can be cleaned to avoid pipe blockage.

[0084] In this embodiment of the application, a one-way valve is provided on the upstream side of at least one of the first inlet and the second inlet.

[0085] Understandably, a one-way valve (not shown in the figure) is used to prevent backflow of the grout. During grouting operations, the first grouting drive device 431 and the second grouting drive device 432 drive the first and second grouts to flow into the mixing pipe 450, respectively. For the first inlet, if a one-way valve is provided upstream, when the first grouting drive device 431 stops working, the one-way valve will prevent the first grout from flowing back from the mixing pipe 450 to the first supply device 411, thereby protecting the stability and safety of the first grouting branch. Similarly, for the second inlet, if a one-way valve is provided upstream, when the second grouting drive device 432 stops working, the one-way valve will prevent the second grout from flowing back from the mixing pipe 450 to the second supply device 412, thereby protecting the stability and safety of the second grouting branch.

[0086] It should be noted that, in actual operation, the need to install check valves on the upstream side of the first and second inlets can be selected based on the properties or composition of the first and second slurries. This embodiment does not impose any restrictions on this.

[0087] See Figure 1 and Figure 3 In this embodiment of the application, the grouting mechanism 400 further includes: a first injection control console 460, disposed between the first injection drive device 431 and the first inlet, the first injection control console 460 being used to regulate the injection conditions of the first injection branch; and a second injection control console 470, disposed between the second injection drive device 432 and the second inlet, the second injection control console 470 being used to control the injection conditions of the second injection branch.

[0088] The first injection control console 460 is positioned between the first injection drive device 431 and the first inlet, ensuring that it can directly and effectively finely control the injection conditions of the first injection branch. The first injection control console 460 can monitor parameters such as the pressure, flow rate, and component ratio of the first grout in real time, and automatically adjust the output power and speed of the first injection drive device 431 based on a preset grouting plan or real-time feedback data, thereby achieving precise control of the injection conditions of the first injection branch. This improves the efficiency of the grouting operation and ensures the stability and consistency of the grouting quality.

[0089] Similarly, the second injection control console 470 is also arranged between the second injection drive device 432 and the second inlet, ensuring that the second injection control console 470 can directly and effectively finely control the injection conditions of the second injection branch. The second injection control console 470 can monitor parameters such as the pressure, flow rate, and component ratio of the second grout in real time, and automatically adjust the output power and speed of the second injection drive device 432 according to the preset grouting plan or real-time feedback data, thereby achieving precise control of the injection conditions of the second injection branch. This improves the efficiency of grouting operations and ensures the stability and consistency of grouting quality. Through the coordinated work of the first injection control console 460 and the second injection control console 470, the grouting mechanism 400 can simultaneously manage and optimize the operation of the two injection branches, achieving comprehensive control of the grouting process.

[0090] In practice, a thrust sensor can be installed on the push rod 310. When the thrust sensor detects that drilling is complete, it sends a completion signal to the first injection control console 460 and the second injection control console 470. At this time, the first drive device 330 drives the push rod 310 to retract and transmits the completion signal to the rotary mechanism 200. The rotary mechanism 200 moves the grouting pipe 420 to the grouting point (the point where drilling is completed). Then, the telescopic support frame 480 moves the grouting nozzle 440 to the grouting port. After that, the first injection control console 460 and the second injection control console 470 are started to begin the grouting operation.

[0091] After the grouting operation begins, the first injection drive device 431 and the second injection drive device 432 mix the first grout and the second grout according to the actual needs, and then carry out the grouting operation. At the same time, the first injection control console 460 and the second injection control console 470 start to monitor the grouting parameters (such as grouting pressure, flow rate, etc.) in real time. The first grout and the second grout flow through the first injection branch and the second injection branch respectively and are fully mixed. The mixed grout is injected into the grouting point through the grouting nozzle 440. When the first injection control console 460 and the second injection control console 470 detect that the grouting pressure reaches the warning pressure, the rotation speed of the first injection drive device 431 and the second injection drive device 432 will be reduced and adjusted until the grouting pressure reaches the preset pressure, which means that the grouting operation is completed. During this process, the geological monitoring device 500 monitors the geological conditions in real time. The first injection control console 460 and the second injection control console 470 use the geological signals fed back by the geological monitoring device 500 as reference signals. That is, if the grouting pressure has not reached the preset pressure, but the geological signal fed back by the geological monitoring device 500 has reached the maximum saturation value, it means that the gap has been grouted. The first injection control console 460 and the second injection control console 470 then need to control the first injection drive device 431 and the second injection drive device 432 to gradually stop the grouting operation. Thus, through the real-time monitoring of the geological monitoring device 500, the grouting mechanism 400 can be assisted to complete the grouting operation smoothly, effectively improving the injection effect and reducing the stratum disturbance caused by grouting.

[0092] See Figure 1 and Figure 4 In this embodiment, the equipment platform 100 is provided with a moving track 110 extending along the axial direction of the tunnel; the rotary mechanism 200 includes: a rotary table 210, which is movable along the moving track 110 and rotatable relative to the equipment platform 100; a rotary drive device 220, which is connected to the rotary table 210 to drive the rotary table 210 to rotate; and a translation drive device 230, which is located on the equipment platform 100 and connected to the rotary table 210 to drive the rotary table 210 to move along the moving track 110.

[0093] In some embodiments, the equipment platform 100 is provided with a moving track 110 extending along the tunnel axis. The moving track 110 is used for the rotary mechanism 200 to move along the moving track, so that the rotary mechanism 200 drives the drilling mechanism 300 or the grouting mechanism 400 to move.

[0094] Furthermore, to enable the rotary mechanism 200 to drive the drilling mechanism 300 or the grouting mechanism 400 to rotate, the rotary mechanism 200 is equipped with a rotary table 210. The rotary table 210 can slide flexibly on the moving track 110 and rotate relative to the equipment platform 100 (for example, rotate 180° clockwise or 180° counterclockwise). In this way, the grouting device 10 can cope with the complex and ever-changing construction environment inside the tunnel, enabling the drilling mechanism 300 and the grouting mechanism 400 to reach any point for drilling and grouting operations.

[0095] To enable the rotary table 210 to rotate, the rotary mechanism 200 is equipped with a rotary drive device 220. The rotary drive device 220 is connected to the rotary table 210 through an efficient transmission mechanism. When a control command is received, the rotary drive device 220 can quickly and accurately drive the rotary table 210 to rotate clockwise or counterclockwise to meet the operating requirements of different angles.

[0096] Meanwhile, to ensure that the rotary table 210 can move smoothly along the moving track 110, a translation drive device 230 is also installed on the equipment platform 100. The translation drive device 230 is also connected to the rotary table 210 through an efficient transmission mechanism. The translation drive device 230 can precisely control the rotary table 210 to move forward, backward, or stop on the moving track 110 according to the operation requirements, thereby achieving precise adjustment of the operation position.

[0097] See Figure 1 and Figure 4 In this embodiment of the application, the rotary table 210 includes a first section 211 and a second section 212 distributed sequentially along the tunnel axis. The first section 211 is located on the side of the second section 212 facing the equipment platform 100. The drilling mechanism 300 is located on the second section 212. An observation platform 213 is provided on the first section 211 for observing the grouting status.

[0098] It should be noted that the first segment 211 can serve as the fixed end of the rotary table 210 and be fixedly connected to the translation drive device 230. Through the sliding of the translation drive device 230 on the moving track 110, the first segment 211 can slide relative to the moving track 110, thereby causing the rotary table 210 to drive the drilling mechanism 300 and the grouting mechanism 400 to slide. Furthermore, an observation platform 213 is provided above the first segment 211 to allow workers to directly observe the grouting operation process. Through the observation platform 213, workers can monitor the grouting status, including the grouting speed, pressure, flow rate, and distribution of the grouting material, thereby ensuring the quality and safety of the grouting operation.

[0099] In this way, the combined use of the rotary mechanism 200, the drilling mechanism 300 and the grouting mechanism 400 replaces the previous manual drilling and grouting process. The staff only needs to monitor and control the grouting device 10 to realize the drilling and grouting operations, which improves construction efficiency, reduces labor costs and saves construction time.

[0100] Furthermore, the second section 212 can serve as the rotating end of the rotary table 210, rotating relative to the equipment platform 100 under the drive of the rotary drive device 220. Both the drilling mechanism 300 and the grouting mechanism 400 are mounted on the second section 212. Through the rotation of the second section 212 and the sliding of the second section 212 relative to the moving track 110 driven by the first section 211, the accuracy of the drilling position, the smooth progress of the drilling process, and the successful execution of the grouting operation are ensured.

[0101] It is understood that the rotary mechanism 200 can also be a rotary robotic arm, crank rocker, etc., with the purpose of enabling the drilling mechanism 300 and the grouting mechanism 400 to move at any point. This embodiment does not impose any restrictions on this.

[0102] On the other hand, this application provides a tunnel boring machine, including the grouting device 10 provided in any of the above embodiments.

[0103] The grouting device 10 has been described in detail in the above embodiments and will not be repeated here.

[0104] In summary, the grouting device and tunnel boring equipment provided in this application include a grouting device 10 comprising a rotary mechanism 200 movable along the extension direction of the equipment platform 100 and rotatable relative to the equipment platform 100. The rotary mechanism 200 is equipped with a drilling mechanism 300 and a grouting mechanism 400. Through the rotary mechanism 200, the drilling mechanism 300 and the grouting mechanism 400 can achieve full coverage of any point on the tunnel lining segments. When the geological monitoring device 500 detects a gap between the tunnel lining segment and the tunnel wall, it transmits the location signal requiring drilling and grouting to the rotary mechanism 200 and the drilling mechanism 300 via the control module. The rotary mechanism 200 then drives the drilling mechanism 300 to move to the gap to perform drilling operations. Then, the rotary mechanism 200 drives the grouting mechanism 400 to move to the borehole for grouting. During the grouting process, the grouting mechanism 400 can automatically control the grouting operation according to the grouting pressure. At the same time, the geological monitoring device 500 monitors and analyzes the gap in real time. When the gap is detected to be filled by grouting, the grouting mechanism 400 can be stopped by the control module. Thus, by setting up the geological monitoring device 500 and the control module, the gap position can be accurately determined, as well as whether the gap has been filled by grouting, avoiding over-grouting or under-grouting, and improving the grouting effect.

[0105] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
