Danger removing and strengthening seepage control method for barrier lake natural rock-fill dam

The invention belongs to the technical field of seepage control in hydraulic engineering, and particularly relates to a danger removing and strengthening seepage control method for a barrier lake natural rock-fill dam. The method comprises the steps of pouring a concrete cap weight layer of the rock-fill dam; installing a borehole orifice-pipe; performing boring construction; and performing grouting construction. According to the danger removing and strengthening seepage control method for the barrier lake natural rock-fill dam, consistence of grouting slurry is adjusted at any time during thegrouting construction, so that a better seepage control effect can be achieved and stability is improved; the pipe fixation problem is solved by an employed small diameter boring and grouting technology; and construction cost is effectively reduced by the employed grouting slurry material. 本发属于属于水利工程防渗技术领域，尤其涉及一种堰塞湖天然堆石坝除险加固防渗方法，步骤包括：浇筑堆石坝的砼盖重层；设置孔口管；钻孔施工；灌浆施工；本发明所述堰塞湖天然堆石坝除险加固防渗方法，在灌浆施工过程中随时调整灌浆浆液的稠度，能够达到更好的防渗效果并提高稳定性，采
