Anchoring structure for foundation pit protection

The utility model discloses an anchoring structure for foundation pit protection. The anchoring structure comprises an anchoring strip and an anchoring head. The anchoring strip is formed by sequentially connecting a plurality of anchoring chain links; each anchoring chain link comprises an anchor cable and an anchor rod; the anchoring chain links are sequentially connected with the anchor rods through the anchor cables. The chain type anchor rod is ingenious in structural arrangement, the chain type anchoring body is ingeniously designed, the flexibility of an anchoring chain link anchor cable is adopted, meanwhile, the rigidity of the anchor rod is achieved, the anchor cable bears tensile force, the longitudinal anti-sliding force is improved, the anchor rod is beneficial to supplementing the rigidity and strength affected by drilling, and the foundation pit supporting effect of anchoring is improved in cooperation with grouting. An anchoring chain link is further specifically designed, rib thorns are arran
