Zusammenfassung: | The invention discloses a horizontal wire-line coring in-drill-hole water burst blocking device which comprises an annular main body, blades and an elastic reset part, the multiple blades are sequentially hinged to the side wall of one side of the main body in the circumferential direction, the multiple blades are sequentially connected on one side of the main body in a petal shape, and when the blocking device is in a closed state, the elastic reset part is arranged on one side of the main body. The multiple blades abut against one another in sequence to form a closed structure. And an elastic reset part is arranged between the blade and the main body. According to the invention, through the plurality of petal-shaped blades which are sequentially connected and arranged on one side of the main body and the elastic reset part, the blades are opened and automatically reset and closed, so that gushing water in a drill hole is flexibly blocked, and the gushing water is prevented from rushing out of a drill rod wh |
