Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering operations, and particularly relates to a non-entry well plugging airbag structure. Background Art

[0002] In urban construction, during the inspection, detection, and pipeline repair operations of pipelines in rainwater wells or sewage wells, construction workers usually use plugging airbags to temporarily plug the operating pipe sections in rainwater wells or sewage wells. The plugging airbag is an ideal tool for the inspection, detection, pipeline repair, and silt treatment of pipelines in rainwater wells or sewage wells.

[0003] The working principle of the plugging airbag is that a pipeline plugging airbag made of excellent rubber is inflated. When the gas pressure in the water blocking airbag reaches the specified requirement, the water blocking airbag fills the entire pipeline cross-section, thereby temporarily plugging the pipe section.

[0004] The existing plugging airbag structure mainly consists of an airbag, an air pipe, and an air pump. One end of the air pipe is connected to the airbag, and the other end of the air pipe is connected to the air pump. The plugging operation of the existing plugging airbag is usually carried out by workers entering the well, placing the plugging airbag into the pipeline of the rainwater well or sewage well, and then the air pump conveys gas into the air pipe to inflate the airbag to complete the plugging operation.

[0005] The existing plugging airbag structure has the following deficiencies: the existing plugging airbag structure requires workers to enter a confined space for plugging, which is difficult to operate manually. Workers entering a confined space for operation is too dangerous and there are safety hazards. The labor cost required is also high, the operation efficiency is low, and the construction requirements for workers are high.

[0006] Currently, some manufacturers also fix a support rod on the plugging airbag and use the support rod to insert the plugging airbag into the pipeline of the rainwater well or drainage well. Although it can achieve the purpose of not requiring workers to enter the well, this plugging airbag structure also has some deficiencies:

[0007] 1) The support rod is fixedly connected to the plugging airbag, which is not convenient for adjusting the angle of the plugging airbag and cannot quickly move the plugging airbag into the pipeline to be plugged, resulting in low operation efficiency.

[0008] 2) The length of the existing support rod is fixed and cannot be adjusted, so it cannot adapt to the pipeline plugging of rainwater wells or sewage wells with different depths, and has a narrow practical range and poor flexibility. Content of the Utility Model
