Borehole casing water outlet reinforcing device and method
The invention relates to a borehole casing water outlet reinforcing device and method. In order to overcome the defects in the prior art, the borehole casing water outlet reinforcing device disclosed by the invention comprises a grouting pipe; a plurality of grouting holes are formed in the side wall of the middle section of the grouting pipe; and the borehole casing water outlet reinforcing device is characterized in that a drainage pipe is further arranged in the grouting pipe in a penetrating mode; the upper and lower grouting end ports and the drainage pipe are respectively sealed through taper-pipe-shaped or circular-ring-shaped sealing plates; the upper portion of the grouting pipe is fixedly connected with two outer protruding rings; an expandable sealing sleeve is arranged between the two outer protruding rings; the axis of the grouting pipe coincides with the axis of the drainage pipe; the grouting pipe and the drainage pipe are both divided into a plurality of sections; and the adjacent upper and lower sections are respectively in threaded connection through sealing pipes. The invention further relates to a corresponding borehole water outlet reinforcing method. The borehole casing water outlet reinforcing device is simple in structure, convenient to use and suitable for carrying out rapid grouting reinforcement and plugging on a water inrush borehole.
本发明涉及一种钻孔套管出水加固装置及方法。为克服现有技术缺陷，本发明钻孔套管出水加固装置包括注浆管，该注浆管中段侧壁上开有多个注浆孔，其特征在于：所述注浆管内部还穿设有一引流管，所述注浆上下端口与引流管之间分别通过一个锥管形或圆环形封板封闭，所述注浆管上部固连有两个外凸环，两个外凸环之间设有可膨胀密封套，注浆管轴心线和引流管轴心线重合，二者均分成多节，相邻的上下两节分别通过密封管螺纹连接。本发明还涉及相应钻孔出水加固方法。本钻孔套管出水加固装置结构简单，使用方便，适合对突水钻孔进行快速注浆加固和封堵。
