Adopt multiple steel strands of corresponding tonnage to form flexible cables.
Steel strands are coated with anti-rust grease, single strand wrapped with polyethylene, and the whole bundle wrapped with polyethylene pipe to form three-layer anti-corrosion anchor cable.
Both ends of steel strands are integrally pressed and anchored by anchoring pipes, then external threads are processed on anchoring pipes and locked with nuts, featuring good elasticity and high safety.
2. Spring
Conical spring is adopted to bear large displacement caused by earthquake.
Steel strand relaxation can be absorbed by the spring.
