Permanent anchor rope used for side slope stabilization
A permanent and stable technology, applied in sheet pile walls, excavation, construction, etc., can solve problems such as loss of overall anti-corrosion function of cement slurry stones, hidden dangers of long-term safe operation of the project, and reduction of tension relaxation of cables, etc., so that it is not easy to crack , prevent the infiltration of groundwater, and maintain the effect of tension for a long time

[0027] Specific implementation plan
[0028] The cable 8 in this example uses an unbonded steel strand with a PE protective layer. There are six unbonded steel strand cables 8 and three sets of load-bearing components A1, A2, A3, and the lower ends of the six cables. Divide into three groups evenly, and fix them symmetrically on the bearing plates 2 of the three groups of load-bearing components (see Figure 1). The cables 8 pass through the centering frame 6 in parallel to keep the cables parallel and ensure that the cables are placed in parallel. Anchor hole center. The upper ends of the six unbonded steel strand cables are tensioned and fixed with the outer anchor head III, so that the cement paste stones of the inner anchor section I transfer the tensile force of the outer anchor head to the foundation in the form of compression. Because the cement paste stones have the characteristic that the compressive strength is much greater than the tensile strength, they will not produce...
