A kind of protective cover for cable-stayed bridge cable and using method thereof

Abstract

The invention discloses a protective cover for a cable-stayed bridge cable and a method for using the same, and belongs to the technical field of bridge safety. A protective cover for a cable-stayed bridge cable includes a main protection mechanism, a sealing head mechanism and a cable. Both ends of the mechanism are provided with a sealing head mechanism. The main protection mechanism includes an outer protective cover. There are two symmetrical inner connection sleeves inside the outer protective cover. The inner wall of the outer protective cover is fixedly connected with a water injection pipe. A plurality of evenly distributed water injection holes are opened on the outer wall on the side away from the outer protective sheath. It can realize that the protective cover will not elongate with the force of the cable body when the cable is stretched, which can prevent the protective cover from working under stress, thereby making the protective cover not easy to damage and having a long service life, thereby preventing the cable from being corroded damage, and also reduces the cost of maintenance and replacement of the protective cover, and is easy to install and operate, and has a better protection effect on the cable.

Description

technical field [0001] The invention relates to the field of bridge safety, in particular to a protective cover for cable-stayed bridge cables and a method for using the same. Background technique [0002] Cable-stayed bridge, also known as cable-stayed bridge, is a bridge in which the main girder is directly pulled on the bridge tower by many cables. structural system. It can be regarded as a multi-span elastically supported continuous beam with cables instead of piers. It can reduce the bending moment in the beam body, reduce the height of the building, reduce the weight of the structure, and save materials. Cable-stayed bridges are mainly composed of towers, girders, and cables. [0003] Cables are important components of cable-stayed bridges. Long-term exposure to wind, rain, humidity, and polluted air can cause stress corrosion, fatigue corrosion, and metal corrosion, which makes the cables vulnerable to corrosion damage. In order to ensure the safety of the bridge, ...

AI Technical Summary

Problems solved by technology

[0004] Wrapping the protective cover on the surface of the cable is the most common protective measure for the cable. However, the cable protective cover in the prior art, when the cable is stretched, the protective cover will elongate with the force of the cable body, so that The protective sleeve works under stress for a long time, which leads to short service life and easy damage of the protective sleeve, which in turn easily leads to corrosion damage of the cable
