Background

Transportation considerations are particularly relevant when constructing large infrastructures in tidal flat areas (typically including water-land intersections such as lakes, rivers and offshore). The construction environment of the beach area is mainly characterized in that: the bearing capacity of the foundation is low, and water are alternately generated. Because the offshore beach area is submerged by seawater during flood tide and exposed out of the sea during ebb tide, a common transport ship is difficult to enter the beach for operation due to deep draft, and a small ship with shallow draft cannot meet the construction requirement due to low efficiency; if the trestle is built, the problems of overhigh investment cost, overlong construction period and the like exist. However, the existing intertidal transport equipment developed internationally, such as air cushion transport vehicles, hovercraft and the like, are not suitable for carrying the transport work of offshore intertidal wind power plant construction and installation materials due to the factors of small load, large power consumption, high cost and the like.
