Method for placing large-weight hull in dock during construction and high-bearing anti-settling docking block

Abstract

The invention relates to a method for placing a large-weight hull in a dock during construction. The method comprises the following steps: calculating the stress conditions of different supporting points at the bottom of the hull, and setting different docking block supporting modes according to different stress magnitudes and the self-bearing capacity of the dock, so that the weight of the hull is uniformly distributed at the bottom of the dock. The utility model further relates to a high-bearing anti-settling docking block which structurally comprises a base, a supporting round block and a steel docking block, the base is a large-contact-surface base structure made of reinforced concrete, and angle steel is fixed on frames at four corners of the large-contact-surface base structure. According to the method and the special docking block, the bottom of the dock is effectively prevented from settling while the weight of the ship is borne, the method ensures that a ship engine room area building base line is kept horizontal, and guarantees ship building benchmark and precision.

Description

technical field [0001] The invention relates to shipbuilding, in particular to a method for placing docks in a dock during construction of a large-weight ship and a special high-load anti-settling dock. Background technique [0002] Due to the rise of container shipping, due to cost considerations, ship construction tends to be large-scale, and the overall tonnage of the ship itself is also increasing. These large ships include container ships, bulk carriers and other ship types. The construction of these ships often requires corresponding docks. Matching, but the shipyard has a limited number, and generally builds various types of ships. [0003] During the construction of large ships, some types of ships will cause the weight of the stern engine room area to be particularly heavy. At the linear contraction of the stern of the ship, the weight of the ship is all concentrated on a row of docks on the centerline of the hull at the bottom of the hull. Often puts a lot of pres...

Problems solved by technology

In practice, this row of dock piers will cause the bottom of the dock to settle during the actual construction, and the wooden pads will produce vertical deformation, resulting in an out-of-tolerance deviation of the ship's construction baseline, and the hull construction benchmark cannot be guaranteed
