Double Shield TBM's Electrical and Mechanical Systems: The Evolution from Automation to Intelligence
In terms of mechanical systems, the Double Shield TBM relies on a precise propulsion system and rotating cutter head, continuously overcoming technical bottlenecks to achieve more efficient tunneling. In the past, the operation of tunnel boring machines, including propulsion and cutter head movements, relied heavily on manual adjustments and control. However, with the integration of electrical and mechanical systems, the TBM now operates with fully automated and precise functions. The propulsion system of the hard rock tunnel boring machine-double shield TBM uses intelligent algorithms to calculate the optimal advancement path and cutting force, automatically adjusting the cutter head’s rotation speed and cutting pressure to handle varying rock hardness and structures. The introduction of this automated control system not only improves the speed of construction but also significantly enhances operational precision and stability, especially in hard rock or complex geological conditions.
With further advancements in intelligent technology, the electrical and mechanical systems of the Double Shield TBM are evolving toward more intelligent operations. The machine can now automatically adjust its working mode based on geological changes, optimizing itself for more efficient operation. This process is supported by advanced sensor technology and data acquisition systems, which can monitor a wide range of parameters during tunnel excavation, such as geological pressure, machine operational status, and advancement speed. Data analysis systems then process and optimize this information. The inclusion of intelligent systems has not only enhanced the automation level of the TBM but also enabled the machine to respond more flexibly to complex tunneling environments, thereby ensuring the safety and efficiency of tunnel construction.

How to Troubleshoot and Maintain Double Shield TBM
Common failures in Double Shield TBMs usually occur in the propulsion system, electrical control system, and cutting components. For propulsion system failures, operators can assess the condition of the hydraulic system and propulsion motor to identify the issue. Common faults, such as problems with the hydraulic pump or valves, may result in insufficient or abnormal thrust. In such cases, a thorough inspection and maintenance of the hydraulic system are required to ensure the hydraulic oil quality and pressure stability. Failures in the electrical control system typically manifest as signal loss or sensor malfunctions. In these cases, checking the cable connections, sensor functionality, and control panel alarms usually helps quickly identify and resolve the problem. For cutter head maintenance and troubleshooting, operators need to regularly check the wear condition of the cutter tools and the distribution of cutting forces, and replace or adjust the cutter head when necessary. Our Hard Rock Tunnel Boring Machine – Double Shield TBM, with its efficient and automated design, makes troubleshooting and maintenance more precise and efficient, reducing equipment downtime and improving construction continuity and stability.
In actual maintenance operations, in addition to regular inspections and upkeep, the availability of spare parts and on-site technical support is also critical. The design of the Double Shield TBM takes on-site maintenance convenience into account, with many key components such as electrical control modules, hydraulic pumps, and cutter tools being easily replaceable or repairable, reducing downtime during repairs.
