The invention discloses a 
slurry pocket 
slurry-injecting anchorage rod with a 
control system and a using method and belongs to the technical fields of 
engineering construction and anchorage rod fixing. The 
slurry pocket slurry-injecting anchorage rod comprises a rod body part, a control part and a shell, the control part comprises a slurry injecting part and a slurry returning part which are connected in parallel and further comprises a 
control circuit part, and the slurry returning part comprises an adjusting structure. The 
control circuit part comprises a first 
bulb, a second 
bulb and a power source, a normally open switch is arranged above the first 
bulb, and the power source is connected with a normally open 
solenoid valve. The rod body part comprises a shell body, a main reinforcement, a slurry pocket and a pocket interior slurry-injecting 
pipe, a 
metal ball is arranged above a slurry returning opening, and the 
metal ball is connected with the normally open switch of the circuit part in parallel through an electric conducting 
metal bar. The slurry pocket slurry-injecting anchorage rod with the 
control system and the using method have the beneficial effects that the extraction-resisting capacity of the anchorage rod can be reinforced through control over the slurry-injecting shape, the slurry-injecting pressure can further be accurately controlled through the 
control system, and the technical problems that as for an ordinary slurry-injecting anchorage rod, the slurry 
backflow pressure is overlarge and slurry run-out and leaking are prone to occurring are solved; and theslurry pocket slurry-injecting anchorage rod has the advantages of being simple in structure, low in cost, rapid in mounting, capable of being reused and the like.
