The invention relates to the technical field of slope anchoring devices, in particular to a seismic resistant modular anchoring device. The seismic resistant modular anchoring device includes anchoring rod bodies, the anchoring rod bodies are of hollow structures, the anchoring rod bodies include anchoring sections and free sections, the free sections are provided with a plurality of impedance elements, latex films sleeve the anchoring rod bodies among the adjacent impedance elements, elastic sealing spaces for holding grouting bodies are arranged among the latex films and the anchoring rod bodies, and the anchoring rod bodies sleeving with the latex films are provided with reserved holes for communicating with the internal parts of the anchoring rod bodies and the elastic sealing spaces.According to the seismic resistant modular anchoring device of the technical scheme, in the free section, the latex films are used for forming the wrapped grouting bodies, the splitting action in thegrouting process is limited to avoid affecting the integrity of surrounding rock and earth masses, the rubber impedance elements are preset among the grouting bodies in the free sections as shock absorbers, in an instantaneous strong earthquake, the energy dissipation capacity during asynergic movement among anchoring rods-the grouting bodies-the impedance elements is improved, and then the overall seismic resistant performance is improved.
