Abstract

The invention relates to an inhaul cable structure capable of being filled with dry air and a realizing method thereof. The inhaul cable structure comprises a cable body (11). Two ends of the cable body (11) are respectively connected with an upper anchorage device and a lower anchorage device, at least two stainless steel air inlet tubes (9) are arranged on the upper portion of the cable body (11), and at least two stainless steel air outlet tubes (21) are arranged on the lower portion of the cable body (11). According to the inhaul cable structure capable of being filled with the dry air and the realizing method thereof, water in the inclined inhaul cable body can be drained when the dry air is filled in the stainless steel air inlet tubes, and therefore hazardous substances such as the water can not be retained in the inclined inhaul cable body easily, steel wire corrosion can be avoided, and use stability of an inclined inhaul cable is guaranteed; humidity sensors are arranged on end mouths of the stainless steel air outlet tubes, and therefore environmental conditions of steel wires in the inclined inhaul cable can be monitored through humidity changes after the dry air flows in the cable body, and safety of the inclined inhaul cable is improved.

Description

technical field [0001] The invention relates to a stay cable and belongs to the technical field of bridge engineering. Background technique [0002] The traditional stay cable structure is made by twisting multiple high-strength steel wires at a twisting angle of about 3°, then hot-extruding double-layer high-density polyethylene sheaths, installing anchors at both ends, and adopting a multi-layer sealing system Formed fully sealed stay cable structure. Due to the inevitable damage to the polyethylene sheath of the stay cable during the construction process, even if it is repaired in time, harmful substances such as moisture have entered the cable body and remain in the cable body, causing corrosion of the steel wire and causing the stay cable invalidated. In addition, during the long-term use of the stay cable, the environment inside the stay cable cannot be accurately grasped, which leaves a hidden danger to the safety of the stay cable.
