The invention discloses a leaking stoppage device for bored pile construction and a bored pile construction method, and relates to the technical field of bored piles.The leaking stoppage device for bored pile construction comprises a top pile casing located at the position of a pile hole and a leaking stoppage head hoisted at the position of the pile hole, and a steel rope is arranged on the leaking stoppage head; the leaking stoppage head penetrates through the top pile casing through the steel rope and sinks to the leaking point position in the pile hole; the plugging head comprises a fixed sleeve and a movable sleeve, the movable sleeve is fixedly connected with the bottom of the steel rope, the fixed sleeve is provided with a fixing piece used for fixing the sunken fixed sleeve to the inner wall of a pile hole, an external expansion rod capable of being expanded and bent is arranged between the fixed sleeve and the movable sleeve, and the external expansion rod is arranged around the central axis of the fixed sleeve at equal angles. And a water swelling strip is arranged on the outer surface of the external expansion rod. According to the invention, a corresponding shape can be expanded according to the change of the water leakage position, so that the water leakage gap can be better fit and filled.

    本发明公开了一种钻孔桩施工用的堵漏装置及钻孔桩施工方法,涉及钻孔桩的技术领域,其中钻孔桩施工用的堵漏装置,包括位于桩孔桩孔位置处的顶部护筒和吊装于桩孔漏处的堵漏头,堵漏头上设有钢绳,通过钢绳将堵漏头穿过顶部护筒,并下沉至桩孔内的漏点位置处;堵漏头包括固定套筒和移动套筒,移动套筒与钢绳的底部固定连接,固定套筒上设有用于将下沉的固定套筒固定在桩孔内壁上的固定件,固定套筒和移动套筒之间设置有可外扩弯折的外扩杆,连接围绕固定套筒的中心轴线等角度设置,外扩杆的外表面设置有遇水膨胀止水条。本发明具有根据漏水位置的变化展开相应形状,从而更加贴合和填充导致漏水缝隙的作用。
