The invention discloses an inflatable type water-stop internal expanding ring device for storing underground pipeline water seepage, and relates to the field of underground pipeline projects. The inflatable type water-stop internal expanding ring device comprises a steel ring (1), a steel ring (2), a steel ring (3), a steel ring (4), a steel ring (5), a steel ring (6), a movable bolt (6), a fixedbolt (7), an inflatable type rubber water-stop belt (8), a gas valve (9) and a valve (10). The inflatable type rubber water-stop belt is adopted between a steel sleeve ring and the inner wall of a pipeline for filling, has certain toughness, is not liable to damage, also can generate certain deformation, and can fill a gap between the steel sleeve ring and the inner wall of the pipeline better toachieve certain sealing effect. Meanwhile, the gas valve for the inflatable rubber water-stop belt is reserved on the steel sleeve ring for regulating gas pressure intensity of the inflatable belt inreal time. 本发明公开了种修复地下管道渗水的
