An anti-corrosion anchor rod for anchor support

Abstract

The invention relates to an anchorage supporting anticorrosion anchor rod which mainly structurally comprises plastic-package threaded steel anchor rod bodies, a plastic anchor head, a plastic-package hexagonal connecting sleeve, a plastic-package grouting stop tapered plug, a plastic-package steel base plate, a plastic-package steel plate protection pad, a plastic-package hexagonal nut, a screw hole, a tapered portion and a threaded plastic-package layer. The anchorage supporting anticorrosion anchor rod has the advantages that the anchorage supporting anticorrosion anchor rod aims to overcome the shortcoming that an existing anchorage supporting anchor rod can be corroded easily, various portions and components of the anchor rod are coated by high-polymer plastic materials, the anchor head is directly made of high-polymer plastic materials, accordingly, the anticorrosion anchor rod is advanced and reasonable in structural design, a good anticorrosion effect can be realized after the various portions and the various components of the anchor rod are packaged by plastics, corrosion due to water, acid, alkali and salt substances can be prevented, the anchor rod can be protected in the full-length direction, is anti-collision and is easy to operate, the service life of the anticorrosion anchor rod can be prolonged by 15 times as compared with the prior art, and the anchorage supporting anticorrosion anchor rod can be used under various rock and soil layer conditions and is perfect.

Description

technical field [0001] The invention relates to an anti-corrosion bolt used for anchoring and supporting, and belongs to the technical field of geotechnical engineering anchoring and supporting equipment and components. Background technique [0002] As a supporting component of geotechnical engineering, anchors are widely used in construction, mining, foundation pits, roadways and slope projects. The tight combination between the rock and soil mass stabilizes the rock and soil mass and improves the overall stability of the rock and soil mass. [0003] Because the bolt body is in the rock and soil, especially when it is set in the corrosive stratum, it is greatly affected by water seepage and humidity, which increases the corrosion of the steel bolt and accelerates the corrosion rate of the bolt, which seriously affects the bolt. service life, and even endanger production and construction safety. [0004] The current technical measures for anti-corrosion of anchor rods are ...

Problems solved by technology

[0003] Because the bolt body is in the rock and soil, especially when it is set in the corrosive formation, it is greatly affected by water seepage and humidity, which increases the corrosion of the steel bolt and accelerates the corrosion rate of the bolt, which seriously affects the bolt. service life, and even endanger production and construction safety

[0004] The current technical measures for anti-corrosion of anchors are isolation and insulation, such as using corrosion-resistant steel, galvanizing the anchors, coating with epoxy resin, or installing casings on the anchors, but these technical measures do not Ideal, but the anti-corrosion effect is not good, and there are still many defects. The price of corrosion-resistant low-alloy steel is more expensive, and the galvanized layer and other coatings will reduce the bond strength between the anchor rod and the mortar body; Rods are easy to fall off during transportation and installation. The elongation coefficient of these coatings is small, and cracks are prone to occur during use, and the anti-corrosion function is lost; the construction of anti-corrosion sleeves is complicated, and the joints are easy to seep into corrosive liquids and are susceptible to corrosion
