Problems solved by technology

In the past, the protection method of the anchorage part was generally to put the anchorage into the cable guide, fill part of the sealing material in the cable guide for protection, and then add a waterproof cover to the guide mouth, etc. Due to the constant vibration of the body and the aging of the sealing material, these protective measures will be partially ineffective.

Abstract

The invention relates to the field of inhaul cables of a cable-stayed bridge, in particular to a fully sealed inhaul cable and a utilization method thereof. The fully sealed inhaul cable comprises an anchorage (2), a nut (3), a connecting cylinder (4), a cable body (5), an embedded cable conduit (6), sealant (7) and a damper (8). The fully sealed inhaul cable is characterized by further comprising an anchorage protecting cover (1), quick couplings (11), air outlet plugs (12), an anchor bearing plate (61), a protecting inner container (9) and a thermal-shrinkage protecting tube (10), wherein the embedded cable conduit (6) and the cable body (5) are hooped by the protecting inner container (9), and the protecting inner container (9), the embedded cable conduit (6) and the cable body (5) are hooped by the thermal-shrinkage protecting tube (10). The utilization method of the fully sealed inhaul cable includes filling dry air or inactive gas into the anchorage protecting cover (1) via an air blower. The fully sealed inhaul cable is simple in structure, good in sealing, long in service life and wide in application range.

Description

technical field [0001] The invention relates to the field of cables used for cable-stayed bridges, in particular to a fully sealed cable and a method for using the same. Background technique [0002] The cable is the upper structure of the cable-stayed bridge, and is the most important force-bearing part of the cable-stayed bridge, bearing the weight of the bridge deck. The safety of the cables is related to the safe operation of the bridge, as well as the safety of pedestrians and vehicles on the bridge. The cable is composed of an anchor and a cable body. The cable body is generally composed of high-strength galvanized steel wire and a polyethylene sheath. The polyethylene sheath protects the steel wire from corrosion. The anchors are located at both ends of the cable body. Judging from the current anti-corrosion status of bridge cables, generally speaking, in the entire cable system, the anchorage parts are relatively easy to be corroded because they are exposed to the a...
