The external force that continues to propagate the pipe after the expansion of the pipeline curve
The length of the supporting pipe section in the pipeline
The pipeline cannot expand or contract freely in the axial direction due to the constraints of fixed supports or friction between the pipe and the soil. In pipeline design, it can be considered as a constrained pipeline. The pipeline with negligible axial constraint force can be considered as a constrained pipeline. In pipeline design,Can be inferred as unrestrained pipeline consideration

Definition or description
A method for laying submarine pipelines using a reel-in vessel. First, a certain length of pre-rolled pipe is continuously wound on the reel on land and installed on the fixed frame of the pipe reeling vessel. After the reel-laying vessel arrives at the site, the pipe is unwound from the reel, straightened, and laid to the seabed through the tensioner and the stern inclined slideway. In order to reduce the bending stress during pipeline laying, a mechanical clamping device that can keep the pipe in a tensile state is installed at the pipe laying slideway. The rigid or hinged inclined frame installed at the bottom of the pipe laying vessel is used to support the welded pipe and gradually lower the pipe to the seabed. It is a large-diameter fixed pipe pre-installed on the platform for laying risers. During construction, the riser is pulled from the "type pipe" to the designated position by winch equipment. According to the requirements of submarine pipeline burial, the buried pipe trench is excavated on the seabed. The operation of excavating the buried pipe trench on the seabed is carried out. The towing device that rides on the bottom pipeline by magnetic force sprays high-pressure water or high-pressure gas to flush sand and mud from the bottom of the pipeline to form a groove, and the flushed sand and mud are sucked away by suction. After the pipe sinks into the groove, the mud can be discharged through the movement of the current or waves. The construction method of filling the mud and sand beside the pipe trench to bury the pipe in the trench
The construction method of injecting a large amount of water into the soil around the pipe and using the vibration of the pipe burying machine to hydrate the soil, reduce the soil density and sink the pipe into the sand
The construction method of using mechanical equipment to reversely trench the seabed"Not recommended synonyms
The method of towing the seabed trenching mold by an engineering ship to remove the seabed mold from the trench

definition or description
rigid disc for testing pipe bending when the pipe is put into the trench and the trench is covered with sand.Usually placed in the pipe section after the connection point between the pipeline and the seabed. When laying submarine pipelines by the pipe dragging method, it is a special part used to pull the pipeline. It is connected to the end of the towed pipeline and has an eyelet for tying the towing cable, so that the pipeline is firmly connected to the cable and the traction is transmitted to the pipeline. The pipeline is fixed to the seabed by a pot rod or a rotating rod to resist the effects of waves, tides and buoyancy, and maintain the stability of the pipeline on the seabed. During the offshore construction of the pipeline, if the construction has to be interrupted due to changes in the ocean atmosphere, the pipeline can be released to the seabed in time. During the operation, the pipeline is plugged and placed on the seabed and tied with a buoy so that it can be easily found and recovered during the next operation. The recovery of the pipeline abandoned on the seabed after the pipe is abandoned is not recommended.
