Description

Technical Field

[0001] The utility model relates to the technical field of connection construction, in particular to a construction device for connecting sewage pipelines in suspension without stopping water supply. Background Technique

[0002] In the construction of new sewage pipelines, the connection between the new pipeline and the operating pipeline is a relatively common situation in the pipeline construction process. In the prior art, a patent document with the publication number CN115162489A discloses a construction method for connecting new and old sewage pipes without stopping water supply, which relates to the technical field of new and old sewage pipes. It includes the following steps: S1. Open an operation well and a strengthening well at the existing pipeline and jack the new pipeline into the operation well; S2. Pour concrete slurry between the operation well and the strengthening well; S3. Lift the cutting device into the operation well by a small crane, fix the cutting device to the new pipeline, and then cut the existing pipeline through the cutting device to form a connection port; when cutting, the upstream well needs to pump water with all its strength to lower the water level in the existing pipeline; after cutting, lift the cutting device out of the operation well; S4. Fix the connecting pipe to the existing pipeline through the surrounding component and connect the connecting pipe to the connection port, and then connect the new pipeline to the connecting pipe, so as to realize the connection of the new pipeline and the existing pipeline. This application has the effect that the connection port formed by cutting can be accurately aligned with the new pipeline.
