Abstract
The invention discloses a pre-stressed anchor cable with long service life. The pre-stressed anchor cable with the long service life comprises a pre-stressed anchor cable body, a hardness layer, an anti-aging layer, an electric insulation layer and a wear-resistant layer, wherein the wear-resistant layer is located on the top of the electric insulation layer, the electric insulation layer is located on the top of the anti-aging layer, the anti-aging layer is located on the top of the hardness layer, and the hardness layer is located on the top of the pre-stressed anchor cable body. According to the pre-stressed anchor cable with the long service life, through cooperation of the hardness layer, the anti-aging layer, the electric insulation layer, the wear-resistant layer, polyacrylamide, polyvinyl chloride, polyurethane, phenolic resin, polytetrafluoroethylene, polyvinyl alcohol, polyurethane acrylic resin and nano silicon dioxide, the problem that an existing pre-stressed anchor cableis short in service life is solved, the service life of the existing pre-stressed anchor cable is prolonged, therefore, the using cost of the pre-stressed anchor cable is reduced, use is convenient for a user, the practicability of the pre-stressed anchor cable is improved, and the pre-stressed anchor cable is suitable for being used and popularized.
Description
technical field [0001] The invention relates to the technical field of prestressed anchor cables, in particular to a prestressed anchor cable with long service life. Background technique [0002] By drilling through the weak rock formation or sliding surface, one end (bolt rod) is anchored in the hard rock formation (called the inner anchor head), and then the other free end (called the outer anchor head) is stretched, thereby exerting force on the rock formation. The pressure is used to anchor the unstable rock mass. This method is called prestressed anchor cable, or anchor cable for short. [0003] With the development of science and technology, prestressed anchor cables are used more and more widely, but the existing prestressed anchor cables have a short service life, which increases the cost of using prestressed anchor cables, so it is not convenient for users to use. Reduced utility of prestressed anchor cables. Contents of the invention [0004] (1) Solved technic...
