Description

Technical Field

[0001] The utility model relates to the technical field of pipeline butt jointing, in particular to a butt jointing structure for buried pipelines. Background Art

[0002] With the continuous development of the pipeline installation industry, the pipeline buried support has also been continuously developed. In the process of pipeline burial, people first need to lay the pipeline buried support, use the pipeline buried support to support the pipeline, and use the pipeline buried support to assist the installation of the pipeline.

[0003] During the later stage of operation, pipes are often broken, resulting in waste of water resources or sewage leakage. Therefore, we need to add a bracket to increase the shear resistance of the pipe when burying it.

An elastic band is provided between each adjacent connecting rod, and a fixed cavity for installing the pipe is formed between the elastic band and the two bearings at the upper end. The pipe is set between the arc concave surfaces of the two bearings, and the bottom is wrapped and supported by the elastic band. The utility model can realize the buried support of the pipe, better assemble the pipe, so that when it is squeezed and sheared later, the pipe can have sufficient retreat ability, and the bearing is effectively prevented from shearing, better protecting the pipe. The spring in the plug rod absorbs the shearing and squeezing force during shearing, and the entire device is stretched. This movable retreat structure can greatly increase the safety of the pipe after burial and reduce the risk of shearing later.

After that, after the user clamps the upper fixing shell 303 and the lower fixing shell 301, the upper fixing plate 304 and the lower fixing plate 302 are fastened by the limit screw 5. Then, the user connects the tapered end of the guide tube 405 to the external pipeline. When the connection is tightened, the tapered part is deformed under pressure, filling the interface gap and enhancing the sealing. Then, the sealing ring 406 is in close contact with the pipeline surface to form a uniform seal, effectively preventing medium leakage. Finally, after the pipeline docking work is completed, if disassembly is required, follow the reverse steps.
