Introduction
Yalei Yang is a notable inventor based in Shijiazhuang, China, recognized for his contributions to tunnel boring technology. He holds two patents that focus on improving the efficiency and safety of tunnel boring machines (TBMs). His innovative methods have the potential to significantly enhance the performance of TBMs in various geological conditions.
Latest Patents
Yalei Yang's latest patents include a method for identifying the vibration magnitude of a TBM main beam using geological feature parameters and tunneling feature parameters. This method involves collecting vibration signals and tunneling parameters through in-situ tests, establishing a multivariate regression prediction model, and verifying the model under different surrounding rock conditions. The average relative error of prediction is maintained at 12% or less, providing a quantitative relation between the vibration features of the main beam and the TBM's feature parameters.
Another significant patent is a method for real-time strength estimation, grading, and early warning of rock mass during TBM tunneling. This method establishes a general relation model of equivalent strength of the TBM boring rock mass and applies it to real-time boring construction. It allows for the estimation of an integrity coefficient of the rock mass and provides grading and early warning based on established standards.
