[0002] During the operation of a tunnel, due to factors such as changes in geological conditions, structural aging, groundwater erosion, and heavy traffic, the structure may be damaged or deformed, affecting the safety and stability of the tunnel. In order to deal with these problems, the reinforcement methods during the operation of the tunnel include grouting reinforcement, anchor reinforcement, lining reinforcement and other technologies. These methods are aimed at improving the bearing capacity of the tunnel, extending the service life of the tunnel, and ensuring operational safety.

[0003] However, the above traditional method is a passive rigid bearing method, which cannot repair the existing tunnel convergence and misalignment defects, and has problems such as low construction efficiency, limited reinforcement effect, and great interference with operations. This is where this application needs to focus on improvement. Summary of the invention

Each hydraulic support rod has a built-in servo support head and a displacement sensor. The support force of the hydraulic support rod is adjusted according to the instructions of the central control unit. The integrated frame structure adopts modular design, which is convenient for quick assembly and disassembly during the grouting reinforcement process; During the grouting reinforcement and maintenance process during the tunnel operation period, the servo intelligent monitoring unit monitors the uplift and fall of the tunnel structure and the convergence status of the segments in real time, and transmits the data to the central control unit; the central control unit analyzes the real-time stress conditions of the tunnel through the built-in algorithm, and performs real-time support and force through the adaptive servo support unit, so as to achieve coordination of stress and deformation of the shield tunnel structure under the combined action of external loads.

[0009] The adaptive servo support unit adopts a multi-point support design. Each servo support rod independently adjusts the support force according to the specific stress conditions of the tunnel, ensuring uniform stress on all parts of the inner wall of the tunnel, effectively coping with the misalignment phenomenon that may be caused by local stress concentration problems, and improving the overall stability of the tunnel structure.

[0015] The assembly and disassembly integrated frame structure is located outside the vehicle and equipment limits, allowing the tunnel to be reinforced and repaired while the railway is operating normally, thereby reducing interference with railway operations and improving construction flexibility and efficiency.

[0016] The present invention also provides an assembled shield tunnel adaptive reinforcement and repair servo support system, and a construction method in the reinforcement process during the tunnel operation period, comprising the following steps: Step S1, deployment of an adaptive servo support unit; According to the reinforcement requirements during the tunnel operation period, the layout and quantity of the adaptive servo support units are determined, and the adaptive servo support units are quickly deployed on the inner wall of the tunnel using the assembly and disassembly integrated frame structure to form a temporary support frame; the servo intelligent monitoring unit is used to comprehensively monitor the tunnel structure status, including displacement and pressure data, and to monitor the accuracy and integrity of the data in real time; Step S2, grouting reinforcement of the inner wall of the tunnel; After the adaptive servo support unit is installed, grouting is performed in the grouting holes reserved in the support system according to the predetermined grouting reinforcement plan. During the grouting reinforcement process, the central control unit receives and analyzes the monitoring data, predicts the tunnel deformation trend through the decision algorithm module, and generates servo support force adjustment instructions based on this. The instructions are transmitted to the adaptive servo support unit through the communication interface, and the support force is automatically adjusted to achieve instant reinforcement of the tunnel structure. Step S3, dismantling the adaptive servo support unit; After the tunnel grouting reinforcement is completed, according to the tunnel reinforcement effect and the need for long-term safety and stability, the modular structure of the assembled and disassembled integrated frame structure is used to remove the temporary components that are no longer needed and retain the necessary permanent supports, ensuring that the tunnel can quickly return to normal operation after grouting reinforcement, while also providing long-term stability and safety guarantees for the tunnel; Step S4, continuous analysis and maintenance of monitoring data; After the tunnel grouting reinforcement is completed, the servo intelligent monitoring unit will continue to be used to monitor the tunnel structure status for a long time. The central control unit will regularly analyze the monitoring data, evaluate the stability of the tunnel structure, and adjust the adaptive servo support unit according to demand to achieve long-term health monitoring and maintenance of the tunnel.

[0017] The present invention further provides a computer system comprising a memory, a processor and a computer program stored in the memory, wherein the processor executes the computer program to implement the steps of a construction method of an assembled shield tunnel adaptive reinforcement and repair servo support system during the tunnel operation period.

[0018] The present invention adopts a combination of assembled steel structure segments and servo support systems, and cooperates with external grouting of shield tunnels to form an adaptive reinforcement and repair servo support system, construction method and computer system, wherein the adaptive servo support unit actively applies axial force and force deformation monitoring to adapt to the additional load and deformation generated by external loads and grouting reinforcement in operation, accelerate the repair process, improve the repair quality, and repair the misalignment and other repair processes that cannot be achieved by traditional technology. At the same time, the introduction of assembled segments provides reaction force for the servo support, and the assembly and disassembly are convenient to improve the construction efficiency.
