AI Technical Summary

Technical Problem

The secondary grouting of the existing anchor cable structure has limited effect on improving the integrity of the land and the pull-out resistance of the anchor cable body, and it is difficult to meet the higher requirements of the project construction.

Method used

Three grouting anchor cables are used, including the first grouting pipe, the second grouting pipe and the third grouting pipe. Through normal pressure grouting, the first high-pressure grouting and the second high-pressure grouting, the friction and adhesion between the anchor cables and the solid soil are enhanced.

Benefits of technology

Through three grouting, the integrity of the land and the resistance to pulling of the anchor cable body are significantly improved, the construction quality is improved, and the engineering construction needs can be better met with higher requirements.

Abstract

The utility model provides a three-time grouting anchor cable, and belongs to the technical field of supporting construction. The three-time grouting anchor cable comprises an anchor cable body, a first grouting pipe, a second grouting pipe and a third grouting pipe. The anchor cable body is of a steel strand structure. The first grouting pipe extends into the bottom of the grouting hole from the orifice of the grouting hole and is used for normal-pressure grouting; the second grouting pipe extends into the middle section of the anchoring section of the anchor cable body from the orifice of the grouting hole and is used for primary high-pressure grouting; according to the three-time grouting anchor cable, three-time grouting is carried out through the three-time grouting anchor cable, so that it is guaranteed that grout flows into gaps better, the friction force between the anchor cable and surrounding fixed soil is increased, and the integrality of the land and the pulling resistance of the anchor cable body are more effectively improved.
