Landslide horizontal drain hole drilling tool and construction method
The invention discloses a landslide horizontal drain hole drilling tool and a construction method, the drilling tool is composed of a self-falling drill bit, a retaining wall drill rod and a traction rope, and the construction method is characterized in that after the self-falling drill bit and the retaining wall drill rod are adopted to drill and form a hole, the self-falling drill bit is separated from the retaining wall drill rod, and a processed drain pipe is installed in the hole along the retaining wall drill rod; and then the retaining wall drill rod is withdrawn. The construction method comprises the steps of fixed point measurement, drilling tool machining, drilling machine in-place, drilling and hole forming, muck cleaning, drill bit disengaging, water drain pipe installation, retaining wall drill rod withdrawing and water drain pipe plugging. The problem that the horizontal drainage hole cannot be installed in place due to hole collapse or deflection under the long-distance or soft stratum condition is solved, and the water drainage effect of the horizontal drainage hole in disaster prevention and control is improved.
本发明公开了一种滑坡水平泄水孔钻具及施工方法，所述的钻具由自脱落钻头、护壁钻杆及牵引绳组成，其特点是采取自脱落钻头和护壁钻杆钻进成孔后，使自脱落钻头与护壁钻杆脱离，将加工好的泄水管沿着护壁钻杆安装到孔内，然后再退出护壁钻杆。所述施工方法步骤：测量定点→钻具加工→钻机就位→钻进成孔→清理渣土→钻头脱离→泄水管安装→退出护壁钻杆→封堵泄水管完成。本发明解决了水平泄水孔在长距离或软弱地层条件下因塌孔或偏斜原因无法将泄水管安装到位的难题，提高了水平泄水孔在灾害防治中的排泄水成效。
