Abstract

The invention provides a prestressed anchor cable structure and a one-time grouting construction method of a prestressed anchor cable. The prestressed anchor cable structure comprises an anchor cablehole formed in a soil layer; the anchor cable hole is internally provided with an anchor cable and a grouting pipe, wherein the grouting pipe and the anchor cable are arranged at an interval, and thetail part of the anchor cable protrudes from the anchor cable hole; the anchor cable is a wire harness composed of a plurality of steel strands; a plurality of steel pipes arranged at intervals and side by side are arranged in a section of an anchoring section, the steel pipes are coaxially arranged, the steel strands are arranged along the outer wall of the steel pipes so that the steel strands can be isolated one another, and first fastening ring for fastening the steel strands to the steel pipes are arranged on the peripheries of the steel strands; and the steel strands between every two steel pipes are subjected to bundling independently and the peripheries are fastened by second fastening rings. The grouting pipe and the anchor cable exist independently of each other, so that the anchor cable is buried in slurry conveniently during the subsequent grouting, and the problem that grout needs to be supplemented due to shrinkage of the slurry due to the fact that the grouting pipe is damaged and the grouting pipe is buried in the slurry is solved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a prestressed anchor cable structure and a prestressed anchor cable one-time grouting construction method. Background technique [0002] In general, high slopes in areas with complex geological conditions should be supported by the method of "prestressed anchor cables + lattice beams" to ensure the stability of high roadbed slopes. After the prestressed anchor cable is installed, it needs to be grouted through the pre-buried grouting pipe. The grouting is made of cement mortar. The construction mix ratio is determined after the test comparison. The actual grouting amount is generally greater than the theoretical grouting amount, or The anchorage vent hole is no longer vented and the grout at the hole overflows the thick grout as the standard for the end of grouting. If the grouting is not enough at one time or settlement occurs after grouting, grouting should be added u...
