The invention discloses a closed tube seam anchor rod body and relates to an anchor rod body of a tube seam anchor rod device of geotechnical engineering support. The closed tube seam anchor rod body aims at overcoming the defects of the great effect on anchor force and the failure of anchor rods caused by the fact that the prior longitudinal slotted steel tube rod tube seam anchor rod anchor force is low, the slotted steel tube radial low rigidity elastic deformation restricts the improving of the tube seam anchor rod anchor force and when engineering service time in roadways and the like are long and water sprays, the inner walls of the tube seam anchor rod longitudinal slotted steel tube rod bodies are exposed in the spray water completely and can be corroded easily. The closed tube seam anchor rod body comprises a section local concave hollow high-strength thin-wall steel tube, a seal plate and a retaining ring. An inner groove is formed along the longitudinal direction of the total length. The seal plate is connected and fixed with an inner end opening of the section local concave hollow high-strength thin-wall steel tube, and the retaining ring is connected and fixed with an outer end opening of the section local concave hollow high-strength thin-wall steel tube. Compared with prior tube seam anchor rods, the closed tube seam anchor rod body has the advantages that the anchor force is improved apparently, the anchor force is large, the rock reinforcement effect is good, and the effect on the anchor rod anchor force by exposure of tube seam anchor rod body inner walls in the spray water is prevented.
