Compared with prior art, its advantage is the utility model:
1, the present invention has overcome prior art and exists wire digging line steadiness poor, causes application life short, makes cable stayed bridge have the technical problem of potential safety hazard, and the use value, steadiness and the safety that have improved wire digging line have also extended application life of bridge.
2, the utility model adopts inside and outside two restrictive coating, and the thickness of inner restrictive coating is 1cm-1.5cm, and the thickness of external sheath layer is 1cm-2cm, has increased the steadiness of wire digging line, thereby has increased the steadiness of bridge, has extended the application life of bridge.
3, the utility model adopts sheath and external sheath layer to be plastic layer, and plastics cost is low, and has certain anti-corrosion function, easy to use.
4, the utility model adopts seven wire-cores that are coated with inner restrictive coating to be twisted into the total core of steel wire, can further strengthen the steadiness of wire digging line; Adopt seven wire-cores that are coated with inner restrictive coating to be twisted into the total core of steel wire and be twisted into the total core of steel wire with the wire-core that adopts the six roots of sensation to be coated with inner restrictive coating and compare, structure is more firm, and steadiness is stronger.
5, to adopt described packing material be foam particle to the utility model, foam particle is a kind of its pliable and tough, light weight of novel environment friendly expanded material with high-strength buffering, shock resistance, high resilience, can be absorbed and be disperseed external impact by bending, reaches the effect of buffering; Foam particle cost is low, can with variations in temperature in wire digging line, regulate the temperature of wire digging line, can play effect cool in summer and warm in winter.
