The utility model discloses a high -speed, large -traffic accuse system that flows of moving water karst pipeline of shutoff starches the pad through setting up in the ending of mouth of a river top of gushing of treating the shutoff for ending the thick liquid and covering totally and gush the mouth of a river and gush the water pressure in order to bear, make whole karst pipelines come water todischarge through the leading water pipe, adjusting valve is the velocity of flow with control delivery port water yield and in moving water karst pipeline. The near pass keyhole of the issue of adjusting the distance is given first place to with aggregate and the alternative slip casting of single biliquid, forms and only starches the protective screen together to the thick liquid that dams remote end, the issue of adjusting the distance pass keyhole far away adopts single -fluid and double -liquid grouting to give first place to, is beneficial to the diffusion, the utility model discloses the adjustment is high -speed, huge current buret says and gushes the water flow rate at the mouth of a river, along with gushing reducing of mouth of a river water yield, assemble in moving water karstpipeline under water volume invariant's the circumstances that the water velocity reduces gradually in the karst pipeline, and the porous segmented grouting of rethread has increased the interior shutoff thick liquid retention rate of pipeline to realize the successful shutoff of karst pipeline.
