AI Technical Summary
Existing sealing materials for the ends of anchor cable corrugated pipes are difficult to effectively resist stray currents and are easily affected by environmental factors, leading to a decline in sealing performance. They also have high requirements for construction processes, are prone to gaps, and cannot meet the high requirements for sealing effect.
A composite sealing system consisting of a sealing plug and a knob sleeve is adopted. The sealing is achieved through mechanical interlocking and colloidal sealing, combined with threaded connection and fasteners. A standardized installation positioning benchmark is established to adapt to different specifications of steel strands and grouting pipes.
It achieves the blocking of stray currents and long-term waterproofing, improves sealing performance and construction efficiency, solves the limitations of traditional sealing structures, and ensures the electromagnetic protection and waterproofing effect of anchor cables.
