Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline construction, and in particular relates to a pipeline interface butt-jointing auxiliary device for underground pipeline network construction. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, after the fluid is pressurized by a blower, compressor, pump and boiler, it flows from the high pressure part of the pipeline to the low pressure part. It can also be conveyed by the pressure of the fluid itself or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. During the pipeline construction process, multiple sections of pipelines need to be docked in sequence to form a complete pipeline network system. In the existing pipeline docking construction process, the docking angle needs to be manually adjusted so that multiple sections of pipelines can be coaxially connected. This process is complicated to operate and requires a lot of time to complete, resulting in low construction efficiency. After the docking is completed, the coaxiality between the pipes is low and needs to be adjusted twice. Therefore, a pipeline interface docking auxiliary device for underground pipeline network construction is needed to solve the above problems. Utility Model Content
