Description
Technical Field
The invention relates to the technical field of ship manufacturing, in particular to a ship water channel structure arrangement method and a ship.
Background
For ships with higher stability requirements, a stabilizing water tank and a system or a device for traversing water immersion are usually arranged, and side tanks on the left side and the right side are required to be communicated, so that water channel communication is arranged between the two side tanks. The water channel is an interlayer between two layers of platform decks, and in order to ensure the firmness of the water channel, a structure with enough strength is arranged in the interlayer of the platform decks, and the arrangement method mainly comprises two methods. One is that rib plates and stringers are arranged in a crisscross manner, and a large number of large-size openings are arranged on the stringers so as to ensure the area and speed of water flow left and right; and the other is that a first rib plate is closely arranged at each rib position, and the rib plates are provided with flat steel, flat-bulb steel and other support materials for reinforcing the rib plates.
Both arrangement methods can meet the requirement of water flow penetration of a water channel, but longitudinal stringers or support materials exist, so that water flow is blocked to a certain extent, the water flow is not smooth enough, the efficiency is low, and the energy loss of a device system is increased to a certain extent. The first arrangement method is that the steel material consumption is relatively high due to the arrangement of the stringers, the welding of the stringers and the deck of the water channel platform is increased, and more time is required to calculate the balance so as to ensure that the open area is enough. The second approach does not provide stringers, meaning that the span of the rib plate can be large. If the rib plate structure is too weak, the rib plate needs to be thickened besides the support material. When the upright posts are required to be arranged on the deck of the water channel platform, the risk of stress concentration exists. If necessary, an additional reinforcing structure is required to be arranged on the outer side of the water channel, so that materials are wasted, and the arrangement space outside the water channel is occupied.
Accordingly, there is a need for a ship waterway structure arrangement method and a ship to solve the above problems.
