The structural type of the mud pit of the trailing suction hopper dredger mainly depends on the type of a deck and the type of the bottom, and common types of the deck of the mud pit are mainly divided into a conventional single deck type with the coaming of the mud pit and a full-through deck type without the coaming of the mud pit; the common bottom types of the mud tanks are divided into single-row mud gates (V-shaped mud tanks) and double-row mud gates (W-shaped mud tanks) according to different mud gate arrangements. The full-open deck type freeboard is rich, is more suitable for remote operation, and is large in deck area and convenient for equipment arrangement; the single-row mud door has the advantages of simple structure, less mud doors, low cost, convenient maintenance, less bottom member reduction, and more benefit to the total strength and transverse strength of the ship body. The advantages make the mud cabin structure type of the full-open deck and the single-row mud door widely adopted. In order to support equipment such as a drag head harrow pipe, a walking crane and the like which are placed on the full-pass deck, a top side triangular cabin is required to be arranged below the full-pass deck, and compared with a box-type keel of a double-row mud door, the bottom side triangular cabin of the single-row mud door occupies larger space, and part of cabin capacity is lost.
The volume of the existing mud cabin type of the single-row mud door is naturally smaller than that of the mud cabin type of the double-row mud door. In the current mud cabin type of a single-row mud door, watertight bulkheads of a top side triangular cabin and a bottom side triangular cabin are usually flat plates, the cross sections of the watertight bulkheads are straight lines, the watertight bulkheads are changed into outwards concave plates with radians, and the cross sections of the watertight bulkheads are curved lines, so that the volume of the mud cabin can be increased.
