Description

TECHNICAL FIELD

[0002] The currently commonly used dredging boat mainly includes two kinds of cutter suction and rake suction, and both of the two kinds of dredging boats need to be equipped with a dredging pipeline during operation. The dredging pipeline is used to cooperate with a mud pump and high-pressure water flow to break underwater silt, sandstone and other sediments to form a mud mixture, which is then transported to a designated area (such as a reclamation area or a mud treatment facility) through the pipeline.

[0003] A dredging wear-resistant pipeline for dredging boat is disclosed in Chinese Patent No. CN222513222U, which includes mounting flanges arranged at both ends of an HDPE dredging pipe.
