On the other hand, a ship construction method using the above-described floating floating dock (A) will be described.

Ship construction method using the expandable floating dock according to the present invention, the first step (S1) for forming a waterway (W) for the dock arrangement on the coast adjacent to land and sea; Disposing the expandable floating dock (A) in the waterway (W) (S2); Connecting the one end of the fixing means (7) to the expansion part (5) and fixing the other end to the land (S3); 4 steps (S4) of drying the vessel in the expandable floating dock (A); When the ship construction is completed, each step of moving the parts to the expansion unit (5) and the flat portion (2) to place only the dried vessel (B) 5 step (S5); Injecting water into the tank 4 to submerge the main body so that the dried vessel B is suspended in sea water (S6); A seventh step (S7) of launching the dried vessel (B); It is configured to include an eight step (S8) for discharging the water of the tank (4) to cause the floating floating dock (A) to rise.

Step 1 (S1)

Land and sea are dug inland for dock placement on the adjacent shore, forming a waterway (W).

That is, the waterway (W) is wide in the area adjacent to the sea, the width of the portion connected to the inland is formed narrow, when viewed from above is formed in a substantially "凸" shape.

In addition, a second rail R2 is formed on land so as to be connected to the first rail R1 formed on the flat plate 2.

In addition, a fourth rail R4 is formed on land so as to be connected to the third rail R3 of the extension 5.

Step 2 (S2)

The expandable floating dock A is disposed inside the waterway W.

Step 3 (S3)

The rod or connecting bar, which is one end of the fixing means 7, is connected to the expansion part 5, and the body or motor, which is the other end, is fixed to the land.

That is, the fixed structure 76 is installed on both lands of the waterway W, and after the body or motor is mounted on the fixed structure 76, the rod or the connecting bar is connected to the expansion part 5 to expand the floating type. The flow of the dock A can be prevented.

Here, the rod or connecting bar of the fixing means 7 is preferably detachably coupled to the ring formed on the outer side of the extension 5.

Step 4 (S4)

The vessel is built in the expandable floating dock (A).

That is, the ship parts are transported by land or sea, loaded on the expansion part 5, and transported using the crane 200 to carry out assembly of the ship in the flat plate part 2.

Step 5 (S5)

When the ship construction is completed, each part in the flat plate portion 2 is transferred to the expansion portion 5 again by using the crane 200, and only the dried ship B remains on the flat plate portion 2.

In addition, the one end of the fixing means 7 is fixed to the land, and the other end is coupled to the expansion portion 5 further comprises the step of fixing the expandable floating dock (A).

In addition, by installing a rail on the upper surface of the expansion portion 5, by connecting with the rail of the land, another crane moves the rail to the expansion portion 5 while moving and carrying out the assembly of parts in parallel Include.

Therefore, another crane can be moved on the rail, which further improves the efficiency of conveying and assembling the parts.

The crane is preferably a gantry crane, but is not necessarily limited thereto, and may be variously applied to an overhead crane, a jib crane, and a crab crane.

Step 6 (S6)

Water is injected into the tank 4 to submerge the expandable floating dock A so that the dried vessel B is launched in seawater.

In other words, it is not necessary to completely submerge the expandable floating dock (A), only submerged enough that the vessel (B) of the plate portion 2 can be floated by buoyancy.

In particular, before submerging the expandable floating dock (A), the various parts are transferred to the expansion part 5 in advance.

Therefore, when the floating floating dock (A) is submerged, since the expansion portion 5 is fixed by the fixing means (7), there is no change in its height, so that it is substantially raised along the guide rod (6). It is located above the water surface to prevent the inundation of various components.

In addition, since the support force is exerted on both sides by the fixing means 7, the floating floating dock A can be balanced without being shaken.

On the other hand, it is also possible to release the fixed means (7) and move the floating floating dock (A) to the sea and then submerged to launch the ship (B) immediately.

Step 7 (S7)

The launched vessel B is moved. In other words, the launched ship (B) is a state of completion of the drying is driven by its own power or towed by an external tugboat to be dragged to the outside of the waterway and moved to the sea.

Step 8 (S8)

The water in the tank 4 is discharged to allow the floating floating dock A to float.

Therefore, the flat plate portion 2 may be in a state of no water by being raised above the water surface, and other ship parts may be directly loaded on the expansion portion 5 so that the construction work of another vessel may be performed immediately.

In particular, the greatest advantage that can be obtained by the present invention is that the crane is landed by using the first to fourth rails R1 to R4 after the floating floating dock A enters the waterway W and approaches the land. And while moving the expansion part 5 is to enable the assembly and transport work of the parts to improve the work efficiency.

In addition, in some cases, it is possible to work in a state of landing on the land by using the wheel 56 of the expansion unit 5, so that the ship can be directly dried in the floating floating dock (A) by applying the land drying method In addition, when the drying is completed, it is also possible to take advantage of the dock drying method for moving the expanded floating dock (A) to the waterway (W) and submerging the ship (B) to launch.

In addition, since the crane can enter from the land through the first to fourth rails (R1 to R4) to the inside of the expandable floating dock (A), the construction of the next ship can be performed much faster, thereby improving work efficiency. It is.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that the claims fall within the scope of the claims.
