Crushed zone anti-blocking plug, slurry stopping system for preventing out-hole slurry returning and slurry stopping method
The invention discloses a crushed zone anti-blocking plug and a slurry stopping system for preventing out-hole slurry returning. The slurry stopping system comprises a slurry stopping rubber barrel, adrilling device, a slurry injection channel, a barrel protection device, a slurry injection pipe and a water injection pipe. The barrel protection device is arranged at the upper end of the slurry stopping rubber barrel. The slurry injection channel is arranged in the slurry stopping rubber barrel, the slurry injection channel penetrates through an inner cavity of the whole slurry stopping rubberbarrel and extends to the outside of the lower end of the slurry stopping rubber barrel. The slurry injection pipe communicates with the slurry injection channel. The water injection pipe communicates with the slurry stopping rubber barrel. According to the slurry stopping system, an underground slurry soil stone body horizontal baffle can be formed near the depth of the slurry injection channel,the problems that under the condition that the stratum is crushed, slurry returns out of a ground surface hole, and the barrel wall of the slurry stopping rubber barrel and a crushed rock wall are inpoor contact are solved, upper end falling stone is prevented from blocking a slurry injection hole through a semi-rigid protection barrel, and the problem that a slurry stopping plug is hard to recycle is solved.
本发明公开了一种破碎带防堵塞、防孔外返浆的止浆系统。该止浆系统包括止浆胶筒、钻孔装置、注浆通道、注浆装置、护筒装置、注浆管以及注水管。所述止浆胶筒的上端设置有护筒装置。所述止浆胶筒的内部设置有注浆通道，所述注浆通道贯穿整个止浆胶筒的内腔并伸出至止浆胶筒下端的外部。所述注浆管与注浆通道相连通。所述注水管与止浆胶筒相连通。本发明提供的止浆系统，可在注浆通道所在深度附近形成一地下浆土结石体水平挡板，解决了在地层破碎的情况下地表孔外返浆以及止浆胶筒筒壁与破碎岩壁接触不良的问题，并通过半刚性护筒防止上端落石堵塞注浆孔，解决了止浆塞回收困难的问题。
