Recently, the landslide adaptive anchoring system developed by the Institute of Exploration Technology of the China Geological Survey was granted invention patent authorization by the National Intellectual Property Administration (Patent No.: 201410192892.X).
The system consists of boreholes, anchor cables, casings, and bonding materials. Based on the tension-type anchor cable, it uses high-strength low-relaxation steel strands, with anchoring sections set in the sliding bed and sliding mass and a free section at the sliding surface, utilizing the residual sliding force of the landslide to achieve bidirectional anchoring between the sliding bed and the sliding mass. It eliminates the tensioning and locking procedures of conventional anchoring construction and reduces structures such as long free sections and anchor piers for deep landslide anchoring. It features a simple construction method, fast construction speed, and low cost, providing a rapid, economical, and effective reinforcement treatment technical method for deep landslide control.
