Background
The submarine pipeline is a pipeline for transporting oil, gas and chemical agents, and consists of a steel pipe, a heat insulation layer, a weight layer, a heating system and an anti-corrosion system, and is used for communicating an offshore platform, a single point and an onshore oil depot. After the submarine pipeline is put into operation, the submarine pipeline is not limited by water depth and terrain conditions, can continuously convey oil gas and has high efficiency. However, due to the difficulty of repair, the design needs to consider the nature of the transported object and reasonably select the orientation, specification and structure of the pipeline according to the weather, sea state, terrain, geology and other data around the pipeline to ensure safe use. The burying of the submarine pipeline needs to bury the pipeline three times the pipe diameter or 2m deep below the mud surface in order to prevent the sea current from scouring, ensure the stability of the pipeline, anchor the ship and damage the pipeline caused by fishing by a fishing boat. The common method is to use an underwater trencher riding on a pipe to wash away the soil under the pipe with high pressure water, to drop the soil into the trench by the weight of the pipe, and to use the high pressure water to wash the mud back to the landfill. Sometimes, the natural landfill is flushed by sea currents. However, the underwater submersible pipe sinking machine needs an underwater diver to operate, is high in labor cost, difficult to guarantee personal safety, low in construction efficiency and difficult to accurately embed the pipeline, and therefore a brand-new underwater submersible pipe sinking machine is needed to solve the problems.
