Example Embodiment

[0026] Example 1:

[0027] refer to figure 1 and 2 As shown, the present invention discloses a prestressed anchor cable for foundation pit support, the prestressed anchor index comprising: free segment 400 and anchor solid section 500, the free segment 400 and anchor deposition 500 is disposed on drilling 300. The end of the prestressed anchor cable is provided with an anchor 107 and a support 102 that is engaged in the outside of the support 102.

[0028] A plurality of wiring ring 103 are provided with respect to the free segment 400 and the anchoring section 500, respectively. And the spacing of each of the wired ring 103 on the anchoring section 500 is smaller than the spacing of each of the wire ring 103 on the free segment 400.

[0029] The problem of tighsing the hole 300 is more likely to occur, and the present invention is made of a more intensive wiring ring 103 in the anchoring section 500, thereby completing the support of the fixation of the anchor cable and the structur

Abstract

The invention discloses a pre-stressed anchor cable for foundation pit supporting, which comprises a free section and an anchoring section, and the free section and the anchoring section are arranged in a drill hole; the free section and the anchoring section are respectively provided with a plurality of stringing rings at equal intervals; and the distance between every two stringing rings on the anchoring section is smaller than that between every two stringing rings on the free section. The continuous rigid fixed support is finally formed between the flexible pre-stressed anchor cables. And a rigid inner support is used for supporting the inner wall of the anchor hole, protecting the grouting pipe and ensuring the integral forming quality of the pre-stressed anchor cable after grouting. Moreover, the stringing ring is simple in structure, stable, reliable and high in operability; the construction method is simple to operate and high in manufacturing speed; standardized manufacturing can be carried out, labor is saved, and quality is improved; construction is safe, and operation is civilized. Installation is simple, and working efficiency is high.
