| description | The invention relates to a weldable glue injection forming leaking stoppage hoop for leaking stoppage of a large-diameter steel pipe under pressure and a using method of the weldable glue injection forming leaking stoppage hoop. In order to overcome the defects in the prior art, the weldable glue injection forming leaking stoppage hoop for leaking stoppage under pressure of the large-diameter steel pipe comprises two arc-shaped hoop bodies, bolts and a sealing base plate, at least four arc-shaped inner protruding edges are arranged on the inner side face of at least one arc-shaped hoop body, and the two ends of the two arc-shaped inner protruding edges in the middle are connected through short longitudinal protrusions respectively. The two ends of the arc-shaped inner protruding edges on the two sides are connected through long longitudinal protrusions respectively, and the periphery of the sealing base plate is pressed on the outer wall of the pipeline to be plugged through the two arc-shaped inner protrudin |
