Problems solved by technology

[0003] The traditional main cable protection method for suspension bridges is mainly the surface coating method of the main cable. The main cable is protected by painting paint, resin, liquid rubber and other materials on the surface of the main cable for physical isolation. The advantage of this method is that The construction and repair are simple and fast, but in the long-term use process, with the aging, cracking and falling off of the surface coating of the main cable, this method has gradually become unsuitable for the construction requirements of today's bridges, especially as the main cable The application of the internal dry air dehumidification method has higher and higher requirements for the sealing of the main cable

Embodiment

[0017] Embodiment: The protective layer (1) of the present invention adopts colorless transparent saturated polyolefin thermoplastic elastomer as the main material, which has a good isolation effect and can prevent external air and ultraviolet rays from aging the flexible main cable protective material. The skeleton layer (2) is a polyester fiberglass cloth with pores of 2-8mm, which provides strength for the flexible main cable protective material. The film layer (3) is made of modified ethylene propylene rubber, which has excellent weather resistance and elasticity, and can ensure that the wrapping tape moves with the main cable when the main cable is displaced, and at the same time ensures the sealing performance of the main cable.

[0018] The thickness of the protective layer is 0.3-1.0mm. The thickness of the skeleton layer is 0.1-0.3mm. The thickness of the film layer is 0.3-1.0mm. The protective material of the flexible main cable is designed to be white as a whole a...

Abstract

The invention discloses a flexible main cable protective material which is mainly composed of a protective layer (1), a framework layer (2) and a rubber sheet layer (3) and is wound on the surface ofa bridge main cable in a spiral winding mode. Hot-pressing vulcanization is conducted on the protective material through corresponding equipment, and the protective material is solidified on the surface of the main cable, and protects a main cable steel cable. The flexible main cable protective material has excellent isolation and protection effects, can effectively isolate corrosion of natural environments such as wind, frost, rain, snow, salt mist and acid atmosphere to the bridge main cable, has good flexibility, can adapt to the extension change of the main cable, and has a good isolationand protection effect.

Description

technical field [0001] The invention relates to the field of polymer materials, and relates to the anticorrosion protection of the main cable of a user suspension bridge. Background technique [0002] Suspension bridge, also known as suspension bridge, mainly bears the weight of the bridge road surface through steel cables suspended on the cable tower. Among them, the service life of the steel cable main cable is particularly critical, which is directly related to the service life of the suspension bridge. If it is not protected, there will be a possibility of endangering the personal safety of bridge passers-by. [0003] The traditional main cable protection method for suspension bridges is mainly the surface coating method of the main cable. The main cable is protected by painting paint, resin, liquid rubber and other materials on the surface of the main cable for physical isolation. The advantage of this method is that The construction and repair are simple and fast, but...
