As shown in fig. 1, an auxiliary device for plugging a pipeline comprises a circular rubber sheet 5, a flow guide pipe and a filter screen 6. Before carrying out the shutoff of 1 shutoff of mouth of a row of pipeline, clear up row 1 shutoff section of mouth, the barrier is eradicateed, then, filter screen 6 is inside this pipeline shutoff auxiliary device pushes into row mouth 1 towards the pipeline direction. When the rubber pipe is pushed in, the upper end of the round rubber 5 can be deeper than the lower end, an acute included angle is formed between the round rubber 5 and the cross section of the discharge port 1, and the plane where the round rubber is located and the cross section of the discharge port are inclined, so that the contact area between the round rubber 5 and water flow in the pipe can be increased, and the bearing capacity of the round rubber 5 is increased. The diameter of the circular rubber 5 is 1CM slightly larger than that of the row port 1, so that the circular rubber 5 can be in interference fit with the row port 1 to temporarily block the row port 1, and the blocking position is 150CM away from the row port.

Inside the row of mouth 1 of circular rubber shutoff, filter screen 6 sets up the front end at the honeycomb duct, filters sewage, prevents later stage pipe blockage. The mesh size of the filter screen 6 is 1CM × 1CM, and the diameter is 5CM smaller than the diameter of the discharge port 1.

Furthermore, the diameter of the filter screen 6 is 2CM smaller than that of the discharge port 1.

Preferably, the diameter of the filter screen 6 is 1CM smaller than that of the discharge port 1.

The filter screen 6 is connected with a flow guide pipe through a connecting rod, and the flow guide pipe penetrates through the round rubber sheet 5 and extends out of the discharge port 1. The honeycomb duct includes honeycomb duct 2 and honeycomb duct 3 down, goes up honeycomb duct 2 and honeycomb duct 3 down and passes from the upper end and the lower extreme of circular rubber 5 respectively to stretch out row mouth 1. The part of the diversion pipe extending out of the discharge port 1 is provided with ball valves (4, 4 '), and the ball valves (4, 4') control the water flow of diversion. Wherein, the size of the honeycomb duct can be adjusted according to the water flow in the pipeline to be plugged. The front end face and the rear end face of the flow guide pipe are oblique planes, and water in the pipeline flows out of the discharge port 1 through the flow guide pipe. Through the guide and discharge of the guide pipe, the impact of water flow in the pipeline on the circular rubber 5 can be reduced, the circular rubber 5 can stably plug the pipeline, and the mortar plugging position is ensured to be clean and not to be washed by the water flow.

This device is only as the auxiliary device of pipeline shutoff, can not block up the pipeline for a long time, so in case the installation back of accomplishing the device, need carry out the first shutoff of mortar as early as possible, the thickness of a shutoff layer 7 is 20CM, treats a shutoff layer 7 and consolidates the back, carries out the shutoff for the second time, and the thickness of secondary shutoff layer 8 is 20CM, reserves 10CM and cuts off the headspace of honeycomb duct as the later stage.

After the merging of the discharge port 1 and the treatment of the sewage discharge port 1 are finished, the lower guide pipe 3 is used as a slurry inlet pipe, the upper guide pipe 2 is used as a slurry outlet pipe, mortar is poured into the pipeline for plugging by adopting an intermittent grouting method until the concentration of the mortar flowing out of the upper guide pipe 2 is consistent with that of the poured mortar, ball valves (4 and 4') of the upper guide pipe 2 and the lower guide pipe 3 are closed, the guide pipe extending out of the discharge port 1 is cut off after the mortar in the guide pipe is condensed for 7 days, the plugging is carried out for the third time, the thickness of a plugging layer is 10CM, and the surface coating treatment is carried out to ensure the smoothness of the appearance.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
