Description

Temporary quick plugging device for pipeline

Technical Field

The utility model relates to the technical field of pipeline engineering, in particular to a temporary quick pipeline plugging device.

Background

In the construction of rain sewage pipes in municipal works, a water shut-off test is required to check the tightness of the pipes. In the process of the water closing test, the plugging tightness of the pipeline is a necessary prerequisite for the success of the water closing test. When the municipal pipeline is inspected or repaired by adopting non-excavation in the running process, the pipeline also needs to be temporarily plugged.

Currently, the most common temporary plugging of pipelines is the repair using inflatable air bags or masonry concrete blocks.

The conventional plugging process of the inflatable air bag comprises the following steps: construction preparation → pipeline cleaning of the plugging section of the inflatable air bag → positioning of the inflatable air bag → inflation of the inflatable air bag → drainage detection of the plugging effect of the inflatable air bag. The conventional inflatable air bag plugging needs a long time for the air bag inflation process, and reworking is needed due to poor tightness effect after the spherical air bag plugging, so that a large amount of manpower, material resources and plugging time are consumed for temporary plugging; in addition, the air bag has a great potential safety hazard due to the overlong inflation time of the air bag because of the operation of the closed space.

The conventional plugging process of the masonry concrete block comprises the following steps: construction preparation → building concrete in the pipeline to block the pipeline → curing the concrete → carrying out a water-closing test after the concrete reaches the strength. The conventional concrete block plugging not only consumes more time, but also consumes a large amount of manpower and material resources, and the pipeline is extremely easy to damage in the concrete dismantling process after the water closing test is completed, so that secondary damage is caused; and the construction of the concrete blocks in a closed space is also carried out for too long time, so that great potential safety hazards exist.

And for different construction sections, the diameters of pipelines to be plugged are different, different plugging measures are set for pipelines with different diameters, the adaptability is low, and a large amount of manpower and material resources are consumed.

Therefore, it is necessary to provide a temporary rapid pipeline plugging device, which not only can improve plugging efficiency and removal efficiency, enhance plugging tightness, avoid reworking, and be safe and effective, but also can effectively adapt to pipelines with different diameters and sizes, thereby greatly improving adaptability.
