The utility model provides a soil nailing anchor group structure used for remedying ballastless track end tip horizontal deformation hazards. The structure comprises a ballastless track end tip structure which comprises two tracks, a base plate, a friction plate, a small end tip and a large end tip, roadbed faces on the two sides of the small end tip and the large end tip are symmetrically provided with a plurality of grouting holes in the longitudinal direction of the tracks, seamless lining valve steel pipes and grouting bodies are arranged in the grouting holes, and the seamless lining valve steel pipes and the grouting bodies are matched to form the soil nailing anchor group structure. By means of the structure, grouting and reinforcement are carried out on an end tip area roadbed so as to remedy the horizontal deformation hazards of ballastless track end tips.
