A method of building an inland ship

Abstract

The invention provides a building method of an inland ship. The building method of the inland ship comprises the following steps that (1) a hull is divided into seven large parts including a stem portion, a stern portion, a front cabin wall, a rear cabin wall, a port side, a starboard side and a hull bottom; (2) an outer base plate at the hull bottom is built on a ship berth, but an inner base plate is not installed or welded, and other large parts are assembled and welded in workshops or machining platforms; (3) the front cabin wall and the rear cabin wall are hoisted on the outer base plate at the hull bottom, the port side and the starboard side are hoisted, then the internal structure of the hull bottom are welded, the inner base plate is hoisted and welded, and finally the stem portion and the stern portion are hoisted. The building method of the inland ship adopts a large part building method and has all the advantages of block assembly; compared with a segmentation ship berth building method, the building method of the inland ship has the advantages that the ship berth period is shortened, the range of aloft working is reduced, and the labor condition is improved; meanwhile, the building method of the inland ship has other advantages, except outfitting, of a unit construction method, overcomes the defect that according to the unit construction method, a plurality of circumferential weld joints exist, and is particularly applicable to the inland ships with long parallel midships.

Description

technical field [0001] The invention belongs to the field of ship building, and specifically provides a method for building an inland waterway ship. Background technique [0002] Existing ship construction methods include overall construction method, subsection construction method and general section construction method, etc. [0003] Integral construction (also known as bulk construction method) is a method in which the manufactured parts are directly transported to the berth for assembly and welded into the entire hull. It has the disadvantages of long occupation period of the berth, poor working conditions and high production cost. At present, only the shipyards with low lifting capacity still use the integral construction method to build ships. [0004] The segmented construction method is a method in which the parts are welded into various segments in the workshop or processing platform in advance, and the segments are hoisted to the berth for assembly and welded into...

AI Technical Summary

Problems solved by technology

[0007] The berth cycle of inland ships adopting the segmented construction method is still long, and the range of high-altitude operations is still relatively large; the general segment construction method has the disadvantages of large closed circular welds and prone to stress concentration, etc.
