1. Anchor cable production

  Anchor cable while drilling at the scene prepared within the the anchoring segment using corrugated shape, tension segment using the straight-line shape. Feed length of steel strand the anchor cable design length, the anchor head height, the sum of the the jack length of the tool anchor and anchor work thickness and tension operating margin. Under normal circumstances, the strand truncated margin of 50mm. Smooth cut good strand on the job stand, measure out within the anchoring segment and anchor design length, respectively, to make the mark; including anchoring section within wear in isolation bracket, spacing 60 - 100cm between the two pairs of brackets fastened solid ring one; tensioned section per meter tie a tightening ring, plastic tube wear sets within butter; Finally, the guide on the the anchor cable end caps cap.

2. Drilling, cable, grouting the same time

  Connection took over the drill pipe, drill, Slurry Wall, grouting drilling synchronized, the completion of the free end of the the thick grout precession after.

  3 on waist beam

  Using the I-beam connected to the anchor cable.

  4. Tension

  Be mud solidification, two days after the tension.

  5 external protection

  Plugging after grouting, leaving 50mm strand, starting from the anchorage amount, the remaining part of the amputated cement mortar protective layer is not less than 50mm, in its thickness of the external cladding. Xi'an University of Science and Technology Professor Hui hte specializes in bolt and cable technology, there are a number of invention patents. 2009 invention of the self-drilling anchor cable drilling grouting installation time to complete the construction of a new patented technology 2-5 times faster than traditional anchor construction speed, construction costs by 20%.
