The utility model provides a plug for plugging a split bolt hole. The plug solves the technical problems that an existing split bolt hole plugging technology is complex, and efficiency is not high. The plug mainly comprises a plug cap and a plug body, the plug cap is of a disc-shaped structure, the plug body is arranged in the center of the plug cap, and an adhesive layer is further arranged on the plug cap. The plug body is a hollow cylinder or a solid cylinder and is made of water absorption expansion rubber, a chamfer or a fillet is machined at the end of the plug body, and the overall outer diameter of the plug body is larger than the inner diameter of a split bolt hole. By adding the adhesive layer and using the water swelling rubber, the plugging efficiency can be effectively improved, waste of a large amount of manpower and material resources is avoided, and the anti-leakage effect can be well achieved; through a two-layer waterproof structure, the sealing performance of plugging is improved, the servi
