Embodiment Construction

[0018] The present patent will be further described below in conjunction with the accompanying drawings.

[0019] like figure 1 As shown, a single-layer corrugated pipe and a resin material are used to achieve a double-layered anti-corrosion anchor cable structure, which includes an anchoring section 100 , a free section 200 and an anchor head 300 .

[0020] The anchoring section 100 includes a guide cap 101, an external slurry feeding pipe 102 of the anchoring section (the end does not exceed the guide cap 101), a spacer 103, an anchoring section centering support 104, a steel strand 105 for peeling off the PE sleeve and removing grease, and a belt Corrugated plastic casing 107 with anti-corrosion function, external slurry return pipe 108 in the anchoring section, resin injection pipe 109 in the anchoring section, resin return pipe 110 in the anchoring section, and the end of the corrugated pipe in the anchoring section and the guide cap 101 are effectively passed through the...

Abstract

The invention provides an anchor cable structure which adopts a single-layer corrugated pipe and a resin material to realize double-layer anti-corrosion. A corrugated plastic sleeve is arranged on the periphery of the steel strand of the anchoring section; and a resin injection pipe inside the anchoring section is arranged in the anchoring section. And the internal resin return pipe, the external grout feeding pipe and the external grout returning pipe of the anchoring section, the corrugated plastic casing of the anchoring section and the wall of the anchor cable hole are filled with grouting solidified body, and the corrugated plastic casing of the anchoring section is filled with resin. The solidified body is filled. The invention adopts a single-layer plastic corrugated pipe and a resin solidified body to perform double-layer anti-corrosion on the anchoring section of the anchor cable, and adopts a smooth plastic sleeve and a PE sleeve to perform double-layer anti-corrosion on the free section, which provides an effective method for supporting underground caverns. , Anchor cable structure with simpler structure and stronger anti-corrosion ability.

Description

technical field [0001] The invention relates to an anchor cable structure which adopts a single-layer corrugated pipe and a resin material to realize double-layer anti-corrosion, and is mainly suitable for the engineering of stratum reinforcement and allowing proper deformation of the stratum. Background technique [0002] The anchor cable is a rod-shaped component that mainly bears tension. It fixes the steel strand or high-strength steel wire in the deep stable formation through drilling, and generates prestress through tension on the surface of the reinforced body, so as to achieve the The purpose of reinforcement is to stabilize and limit its deformation. The anchor cable consists of anchors, prestressed steel strands or high-strength steel wires and accessories. According to the type of steel strand, it is divided into bonded type and non-bonded type. With the development of anchoring technology, the requirements for the reliability and durability of anchor cables are...
