[ background of the invention ]
In a thermal pipeline system, special sections such as pipelines in cities and towns, roads and railways are mostly laid in an underground manner due to the limitation of external conditions. The factors such as comprehensive economy, construction difficulty and the like, and the corrugated compensator is mostly used for compensating the thermal expansion of the buried thermal power pipeline. At present, a universal corrugated compensator for a buried pipe is fixed by using a screw rod when leaving a factory, and is a transportation pull rod, so that the compensator is ensured not to deform and the pre-deflection amount is not changed in the transportation and installation processes. After the expansion joint is installed, the screw rod is removed according to requirements or the bolt is loosened according to the expansion amount. However, in the actual use process, because the user is unclear about the function of the screw for fixing the expansion joint, the screw is not removed according to the requirement in most cases, or the bolt on the bolt rod is forgotten to be loosened, and hidden troubles are left for the later safe operation of the pipeline.
