Problems solved by technology

[0003] Generally speaking, the distance between one side of the ship and the inner wall of the dock should be at least 5m, but in actual situations, some docks are small in scale and cannot meet the requirement of more than 5m from the inner wall of the dock on one side of the ship, and some even have a distance of only 0.5m, which is fundamental. cannot meet the minimum requirements for shipbuilding

Embodiment

[0068] Please combine Figure 2 to Figure 10 As shown, taking the dock 100 with an effective width of 76m as an example, to build a pipe-sunk ship with a molded width of 75m in the dock 100, the specific steps are as follows:

[0069] S1, build the left ship section 1 and the right ship section 2 in the dock 100 close to the dock walls 101 on both sides, and the distances from the left ship section 1 and the right ship section 2 to the corresponding side dock walls 100 are S1≥5m ;

[0070] S2, seven rows of rails 4 are laid on the dock bottom 3 at the bottom of the left ship section 1 and the right ship section 2, and two sets of 400-ton hydraulic jacking trolleys 5 are respectively arranged on each row of rails 4. The capacity is 5600 tons (the theoretical weight of a single ship section is 4500 tons), and the hydraulic jacking trolley 5 is equipped with a load-sharing beam 6 and a wooden square 7 to contact the bottom of the left ship section 1 and the right ship section 2;...

Abstract

The invention discloses a construction method for a sunken ship with pipe joints in a restricted area. The sunken ship with pipe joints to be built is divided into three ship sections on the left side, the middle and the right side along the width direction of the ship; firstly , build the left side ship section and the right side ship section in the dock close to the dock walls on both sides respectively. The dock wall moves laterally; then, construct the middle ship section in the middle position area in the dock, after completion, assemble the middle ship section with the left side ship section and the right side ship section; finally , undocking the pipe joint sinking ship in which the left side ship section, the right side ship section, and the middle ship section have been assembled. The invention solves the problems existing in the prior art.

Description

technical field [0001] The invention relates to the field of ship building, in particular to a method for building a sunken ship with pipe joints in a restricted area. Background technique [0002] The existing sinking ship with pipe joints is to be built in the dock. During the construction, there must be enough space on both sides of the sinking ship for pipe joints to build ladders, platforms and accommodate construction equipment. Therefore, the pipe joints There needs to be enough construction distance between the two sides of the sunken ship and the inner wall of the dock. [0003] Generally speaking, the distance between one side of the ship and the inner wall of the dock should be at least 5m, but in actual situations, some docks are small in scale and cannot meet the requirement of more than 5m from one side of the ship to the inner wall of the dock, and some even have a distance of only 0.5m, which is fundamental. It cannot meet the minimum requirements for shipbu...
