Abstract

The invention discloses a segmenting method for a cutter suction dredger. The method focuses on the structural characteristics and the installation requirements of the dredger, and divides a steel pile vehicle rail area, a bridge upper and lower hinge joint area, a main generator base and mud pump base area into one segment, and avoids a large annular joint. A stem steel pile vehicle slotted corner and track area, a stern structure slotted corner, a gantry bottom, and a deck large opening corner avoid the segment joint. Thus, during a construction process and after the construction, the accuracy requirement of the stem steel pile vehicle track, the accuracy requirements of bridge closure, the accuracy requirements of the bridge trunnions, the structural strength requirements of the mud pump base and the main generator base, and the strength requirements of the stem steel pile slotted area are satisfied.

Description

technical field [0001] The invention relates to the fields of marine dredging engineering equipment and large-scale ship construction, and more particularly relates to a segmentation method for a self-propelled cutter suction dredger. Background technique [0002] The advent of the segmented shipbuilding method was a milestone in the shipbuilding process. Since then, subdivision has become the basic method of ship construction. How to divide the hull sections will directly affect the entire construction process of the ship, and will have a significant impact on the construction period, construction quality and construction cost of the ship. Therefore, the division method of the hull section becomes the main factor in formulating the ship construction plan and construction policy. [0003] In the process of ship construction, it is necessary to carry out the design work of segment division at the technical preparation stage and the early stage of detailed design, and bring ...
