Embodiment Construction
[0032] The following is attached Figure 1-2 The present invention is described in further detail.
[0033] The embodiment of the present invention discloses a municipal drainage pipeline grouting expansion type air bag sealing structure and its construction method, refer to figure 1 , a municipal drainage pipeline grouting inflatable airbag sealing structure includes a grouting airbag 3, a container 6, a conveying device 5 and two traction devices.
[0034] The container 6 is used to store the expansion slurry, and the container 6 is connected to the slurry-filled air bag 3 through a delivery device 5 . The conveying device 5 includes a slurry pump 51 , a slurry return pump 53 and a hose 52 , and the two ends of the hose 52 are respectively connected to the slurry delivery pump 51 and the slurry return pump 53 . The slurry pump 51 is connected with the container 6, the two ends of the slurry filling air bag 3 are fixed with plugs 31, the slurry return pump 53 is detachably ...

The invention discloses a municipal drainage pipeline grouting expansion type air bag plugging structure and a construction method thereof. The municipal drainage pipeline grouting expansion type air bag plugging structure comprises a slurry filling air bag, a container used for storing expansion slurry, a conveying device and two traction devices, and the two traction devices are connected to the two ends of the slurry filling air bag correspondingly; the two traction devices are used for moving the slurry filling air bag into a pipeline; the container is connected with the slurry filling air bag through the conveying device; when the slurry filling air bag moves into the pipeline, the conveying device conveys the expansion slurry from the container to the slurry filling air bag until the slurry filling air bag completely blocks the pipeline; and when the slurry filling air bag is moved out of the pipeline, the conveying device pumps the expansion slurry back into the container from the slurry filling air bag. The municipal drainage pipeline grouting expansion type air bag plugging structure and the construction method thereof has the effect that the problem that the air bag slides relative to the pipeline under water flow impact is solved.
Description
technical field [0001] The invention relates to the technical field of pipeline repair, in particular to a municipal drainage pipeline grouting expansion type air bag sealing structure and a construction method thereof. Background technique [0002] With the rapid development of cities, the scale of underground pipeline construction continues to expand. The connection between new pipelines and existing pipelines, the closed water test of new pipelines, and the repair and inspection of trenchless pipelines all involve the sealing of upstream and downstream pipelines. A blocking device is used to block the upstream and downstream rainwater and sewage to form a water-less and water-free working environment. [0003] In related technologies, the airbag sealing method is widely used. The airbag is sent into the pipeline, and the gas is filled into the airbag with an inflator to inflate the airbag until the airbag completely seals the pipeline, thereby achieving the purpose of wat...
