Study on the Improvement of Pressure Dispersive Anchor Cable Structure by Pressure Relief Technology

This paper analyzes the structural protection technology under overload conditions, studies the new pressure relief anchorage technology that can meet the requirements without increasing the strength of the tensile components, and uses its continuous constant force output characteristics to improve the structure of the pressure-dispersive anchor cable. The structural principle of the pressure-relief pressure-dispersive anchor cable is proposed, which effectively overcomes the original structural defects of the pressure-dispersive anchor cable. After engineering application, it is proved that its structure is reasonable, anchoring is convenient, and the reliability of construction is greatly improved.
