Prestressed anchoring agent rapid filling device

A prestressed anchoring agent quick filling device relates to the technical field of constructional engineering and comprises a foundation pipe, an end and a piston rod piece, the piston rod piece comprises a rod body, a piston arranged at the front end of the rod body and a handle arranged at the rear end of the rod body, and the front portion of the rod body and the piston are inserted into the foundation pipe. The piston is arranged in the base pipe, the piston is tightly matched with the inner surface of the base pipe and moves back and forth under the pushing of the rod body, the end head is in threaded connection with the front end of the base pipe, a plurality of extrusion holes are formed in the front end of the end head, and the extrusion holes are uniformly distributed in the front end face of the end head. By means of the assembly type structure, the requirement for filling anchor rod holes of various depths with anchoring agents can be met, and the filling efficiency of the anchoring agents is imp
