The anchor cable structure is generally composed of three parts: the amplitude anchor head, the anchor cable body and the outer anchor head. The inner anchor head is also called anchor section or anchor root. It is the foundation for anchor cable to provide prestress in the rock body. According to its structure, it is divided into mechanical type and cemented type. The cemented type is divided into mortar cement and resin cement. Two types, mortar type is divided into two grouting and primary grouting. The outer anchor head is also called the outer anchor section, which is the part where the anchor cable provides tensile tonnage and locking. Its types include anchor plug type, threaded type, reinforced concrete cylindrical anchor pier type, pier head anchor type and steel frame type, etc.; The anchor cable body is a component that connects the inner and outer anchor heads, and is also the bearer of tensile force. The anchor cable body is tensioned to provide prestress. The anchor cable body is composed of high-strength steel bars, steel strands or threaded steel bars.
