The invention provides a non-displacement type two-island building method in a ship dock, which specifically comprises the following steps:
s1, before the ship is docked and carried, according to the construction progress of each position section of the ship body, a first total section 1 in the bow direction and a second total section 2 in the stern direction of the ship body are selected as carrying starting total sections, and a third total section 3 and a fourth total section 4 of a midship of the ship body are selected as embedding total sections.
The first total section 1, the second total section 2 and the third total section 3 are all total sections positioned at the bottom of the ship body, and the fourth total section 4 is a ship body broadside total section.
And S2, respectively hoisting the first total section 1 and the second total section 2 to the corresponding peninsulas, and keeping a set length of the embedding space 7 between the first total section and the second total section.
Since the following first total section and the second total section are mounted and hoisted with other total sections, and the mounting period is long, which may be maintained for 1-2 months, and due to the influence of weather temperature and the influence of mounting and assembling precision and electric welding deformation and shrinkage during the mounting of the total sections, the butt joint surface of the first total section 1 and the second total section 2 may have a certain deformation, as shown in fig. 4, that is, the embedding space 7 between the first total section 1 and the second total section 2 is changed from a theoretical rectangular embedding space to a V-shaped embedding space, so that in order to ensure that the embedding total sections (the third total section and the fourth total section) can be smoothly mounted in the embedding space, the length of the embedding space 7 between the first total section and the second total section should be 15mm longer than the theoretical distance.
S3, according to a carrying construction drawing, taking a first main section 1 and a second main section 2 as carrying starting points, carrying and hoisting other sections of a ship bow and a ship stern respectively with the first main section 1 and the second main section 2 in the same space coordinate system according to a carrying sequence diffused from the starting points to the periphery to form a head island ship body and a tail island ship body, namely, carrying the main sections which are adjacent to the first main section and are positioned around the first main section (upper, lower, left, right, front, rear and upper) on the head island first, and carrying the rest main sections of the ship bow; similarly, the tail island is firstly provided with the block which is adjacent to the second block and is positioned around the second block (upper, lower, left, right, front, rear and upper), and then is provided with the rest block of the stern part of the ship body.
Preferably, the carrying assembly of the other stem sections of the hull bow and the first stem section and the carrying assembly of the other subsections of the hull stern and the second stem section are constructed synchronously, and the central line of the head island and the tail island is controlled within +/-5 mm.
When the first main section 1 and other main sections of the ship bow are carried and assembled, the main sections positioned at any two or more directions around the first main section can carry and operate with the first main section 1 at the same time. During specific carrying operation, a total station is required to be used for monitoring the butt joint precision of a butt joint surface, namely a plurality of monitoring points are selected on the butt joint surface of a first main section, the same number of monitoring points are correspondingly selected on the butt joint surface of a to-be-butted main section (which means segments needing to be carried around the first main section), then the to-be-butted main section and the first main section are drawn together, in the drawing process, the total station is used for detecting three-dimensional coordinates of the monitoring points, so that the butt joint precision between the to-be-butted main section and the first main section is judged, the welding construction sequence of a butt joint is adjusted according to a monitoring result, the butt joint deviation of the butt joint surface is not more than 10mm, and the synchronization deviation of a port and a starboard is controlled within +/-5 mm. When butt seam welding is performed, a weld seam in the height direction is welded first, and then a weld seam in the front-back direction is welded.
The monitoring points on the segments or the block are selected at the locations of their strong structures, such as the intersection between the main deck and the outer plate, the intersection between the inner longitudinal wall and the main deck, the intersection between the deck plate and the inner and outer shells, etc.

According to the total assembly and carrying plan of the total section of a certain container ship, before the ship is docked for carrying, partial compartment sections of the middle section of the cargo hold of the container ship cannot be manufactured according to the original plan, and when the ship needs to be supplied later than the original plan for carrying out subsequent carrying, the container ship can be built by adopting the non-displacement two-island building method in the ship dock.
As shown in fig. 1, according to the construction progress of each position section of the ship body, a first total section HZ03C positioned at the bow part of the ship body and a second total section CZ01P positioned at the stern part of the ship body are used as embarkation starting total sections, a third total section CZ04PS is used as a bottom embedment total section, and a fourth total section HZ12P/S is used as a broadside embedment total section;
arranging a first total section HZ03C on a head island and a second total section CZ01P on a tail island, wherein a certain distance is kept between HZ03C and CZ 01P;
then, the first total section HZ03C is used as a carrying starting total section, and other total sections of the bow of the ship body and the first total section HZ03C are carried out total assembly in the head island to form a head island ship body; taking the second total section CZ01P as a carrying starting total section, and carrying out total assembly and carrying on other total sections of the stern part of the ship body and the second total section CZ01P on the tail island to form a tail island ship body;
the total assembly carrying of the first total section and the total assembly carrying of the second total section have to be controlled in the same coordinate system, and the first total section and the second total section can be carried and constructed synchronously.
After the first total section and the second total section are assembled and carried, an embedding space between the first island hull and the tail island hull is changed into a V shape.
And then, connecting the third total section CZ04PS between the head island hull and the tail island hull by inlaying and hoisting, as shown in FIG. 2, after the third total section CZ04PS is installed, connecting the fourth total section HZ12P/S between the head island hull and the tail island hull by inlaying and hoisting, as shown in FIG. 3, thereby penetrating the head island hull and the tail island hull into a whole ship.
