The invention discloses a mounting structure of a rotary compensator for pipelines on a large-area water domain and a construction method thereof, and relates to the technical field of pipeline construction. The mounting structure of the rotary compensator comprises two pile support platforms; concrete supports are separately fixed to the pile support platforms; a main heat supply pipeline and twoauxiliary heat supply pipes are arranged on the concrete supports; a first support upright column is fixed to the main heat supply pipeline; two pairs of second support upright posts are fixed to theconcrete support; a longitudinally-horizontal steel wire rope and a transversely-horizontal steel wire rope are separately connected between the top ends of the two pairs of second support upright posts; the rotary compensator is welded fixedly to one end of a first elbow; a plurality of suspending lugs are fixed to the first elbow and a second elbow; a plurality of reversible chains are suspended at the top end of the first support upright post; a plurality of reversible chains are suspended on the transversely-horizontal steel wire rope positioned between the second support upright posts; and suspension operations of the first elbow and the second elbow are sequentially carried out through the reversible chains. According to the mounting structure of the rotary compensator for the pipelines on the large-area water domain disclosed by the invention, a suspension operation of the rotary compensator for the pipelines can be quickly carried out, so that the construction is simple and convenient, the operability is strong and the security is high.
Description
technical field [0001] The invention relates to the technical field of pipeline construction, in particular to an installation structure and a construction method for a pipeline rotary compensator on a large-area water area. Background technique [0002] During the use of municipal heating pipelines, when the temperature of the medium transported by the pipeline is different, or when the transmission is stopped for inspection and repair, the metal pipeline will be stretched and deformed due to the large temperature, which will damage the pipeline or pipeline accessories. Therefore, during the construction of municipal heating pipelines, compensation devices will be installed in sections of the pipeline to coordinate deformation, and rotary compensators are often used for rotating devices. The conventional installation method of the rotary compensator is: use a 25t truck crane to hoist the rotary compensator directly to the designated position for welding; however, when the p...
