发明目的——提高封堵质量。孔内灌注器全貌见附图。它包括:有径向孔2的外壳1、钻头3、螺旋式翼片4(其螺线方向与钻头旋转方向相反),弹性圆锥形封隔件5.弹性圆锥形封隔件的下部表面呈突棱状,它装在外壳上,与外壳之间形成空腔6.空腔与外壳轴向孔7连通。钻头3的下部是装有堵塞材料9的容器8,它们用夹板11和螺钉12固定在外壳1的轴向孔10里。 The purpose of the invention - to improve the quality of closure. Hole perfusion picture see the attached drawings. It comprises a housing 1 with radial holes 2, a drill bit 3, a helical wing 4 with a helical direction opposite to the direction of bit rotation, a resilient conical packing 5. The lower surface of the flexible conical packing is Protrusions, which are mounted on the housing, form a cavity 6 with the housing. The cavity communicates with the axial bore 7 of the housing. The lower part of the drill bit 3 is a container 8 containing a plugging material 9 which is fixed in an axial bore 10 of the housing 1 by means of a clamp 11 and screws 12.
