AI Technical Summary
In existing technologies, prestressed anchor cables have poor directional tracking performance during the extraction process, which can easily lead to anchor cable breakage, especially when they are tilted, and there is a lack of effective guiding devices.
A movable frame structure is adopted, combining longitudinal, transverse and inclined frames. The anchor cable is connected by jacks and steel strands. The anchor cable is directionally tracked by gradually drilling through large-diameter and small-diameter casings, with the radial constraint of guide blocks and guide grooves.
It improves the directional tracking effect of anchor cable extraction, ensures that the steel casing is drilled along the anchor cable axis, reduces deviation, and enhances the adjustability and safety of construction.
