| الوصف: | Objective In view of the constant changes of shield tail clearance during shield or tunnel boring machine excavation process, to ensure construction safety, it is necessary to measure shield tail clearance in real-time. Addressing the shortcomings of non-contact shield tail clearance measurement devices, such as poor environmental adaptability, low accuracy, and high cost, the development and implementation of a contact-type, as in mechanical shield tail clearance measurement device is carried out. Method Angle measurement is conducted using a magneto-sensitive angle sensor, and mathematical calculations are then applied to convert the angle values into distance values and obtain corresponding shield tail clearance values, thereby achieving real-time measurement of the shield tail clearance. Result & Conclusion This device undergoes testing and application in engineering sites, demonstrating satisfactory performance. The mechanical shield tail clearance measurement device enables continuous real-time measurement of the shield tail clearance, with measurement data storable locally and accessible remotely, providing high measurement efficiency. Mechanical measurement does not require complex data processing, resulting in relatively high measurement accuracy, controllable within one millimeter. The cost of this device is low, approximately one-fifth of the non-contact measurement device cost, contributing to cost control efforts. |
