Pre-stressed anchor cable for foundation pit supporting
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.
本发明公开了一种用于基坑支护的预应力锚索，所述预应力锚索包括：自由段和锚固段，所述自由段和锚固段设置于钻孔内；所述自由段和锚固段上分别等间距的设有若干架线环；且，位于锚固段上的各架线环的间距小于所述自由段上的各架线环的间距。本发明最终在柔性的预应力锚索之间形成连续的刚性固定支撑。刚性内支撑，支撑锚孔内壁，保护注浆管，保证注浆后预应力锚索整体成形质量。并且，该架线环结构简单，稳定可靠，可操作性强；施工方法操作简单，制作速度快；可进行标准化制作，节约人工，提高质量；施工安全，文明作业。安装简单、工作效率高。
