Latest Patents

Longfei Li holds a patent for a "Test system and method for anchoring performance of full-size rock mass anchor bolt under combined load." This patent describes a test system designed to evaluate the anchoring performance of a full-size rock mass anchor bolt subjected to various loads. The system includes a primary frame, a co-directional pull-twist loading mechanism, and a vertical shear loading mechanism. The primary frame consists of a dual-parallel horizontal reaction frame and a vertical reaction frame. The co-directional pull-twist loading mechanism performs synchronous pull and twist loading for the anchored rock mass, while the vertical shear loading mechanism applies either a static load or simulates dynamic load disturbances. This innovative design allows for separate loading, enhancing the accuracy of performance assessments.
