Inflating plug for plugging grouting hole

The utility model relates to an inflating plug for plugging a grouting hole, which comprises a plug body consisting of a base and a conical inflating channel, the base is in a hollow hemisphere shape,the circular section of the base is connected with the large end of the conical inflation channel, and an inflation hole is formed in the small end of the conical inflation channel. A conical antiskid sleeve is connected to the outer wall of the middle part, and the small end of the conical antiskid sleeve is provided with an inflation cavity communicated with the interior of the conical inflation channel, so that the inflation cavity is inflated and deflated through the conical inflation channel; protruding stripes are arranged on the outer surface of the base and used together with the inflated conical anti-skid sleeve, and the inflation plug can be prevented from sliding out to the maximum extent. The inflation plug is low in manufacturing cost and good in plugging effect, the inflatable conical anti-skid slee
