Description

Building method for a floating dock

The present invention relates to a method of drying a floating dock that allows the ship to be built at sea.

A floating dock is a steel box with a U-shaped cross section that has a number of tanks inside. The tank makes it possible to adjust the buoyancy of the aquaculture dock while the inflow and outflow of water (sea water) takes place via a pump controlled by a control system. Eventually, the amount of seawater filled in the tank determines the degree of flotation of the floating poison.

The characteristics of the above-mentioned floating type dock are to be installed in the place where dry dock is not suitable to enable the ship's construction work, and to avoid the troublesome work of transporting the large ships dried in the dry dock to the remote sea. Thus, it has advantages in shipbuilding field. In addition, in the case of a dry dock adjacent to the coast, civil engineering work should be carried out on a relatively weak ground, and the application of this technique would be difficult in a situation where a ship should be built in a short period of time due to the high technology of selectively blocking high-pressure seawater. Although difficult, the floating dock has the advantage of being able to dry ship quickly regardless of the place and time.

However, since the floating dock has to operate stably while balancing the ship when sinking or rising, the technology applied is not simple. In addition, a considerable manufacturing cost is required to dry the floating venom applied with this technique. This is due to the need to apply technical facilities to meet the demands of coordination of floating information on the floating dock, but most of all, the floating dock is sized large enough to hold the ship. This is because the production fee includes the fee for use of equipment necessary for securing a drying place and transporting and supporting the structure.

Conventionally, the floating dock is dried in a dry dock in which a large vessel is built, or a large barge (barge) constituting the floating dock is individually manufactured on the ground and then assembled or connected by floating on the sea using a marine crane. Was done. However, all of these conventional methods must be equipped with a dry dock, or the long-term use of the offshore crane in order to float and fix the large pants one by one, the excessive expense of the above-described manufacturing costs was inevitable burden.

Therefore, the producer dedicated to the production of aquaculture dock is trying to find a way to proceed more effectively and reduce the production cost while maintaining the conventional specifications of the cultured dock.

Accordingly, the present invention has been invented to solve the above problems, it is possible to proceed efficiently and economically to produce a floating dock that allows the ship to be built at sea, the dried docked dock is dried in a conventional manner It is a technical task to provide a method for drying an intact poison which is not deteriorated compared to the performance of the intact poison.

The present invention to achieve the above technical problem,

Arranging the floor block assembly such that the space faces the ground, transferring the unit blocks to the space, and then connecting the plurality of unit blocks at sea to manufacture the unit block assembly;

A fifth step in which the launching pants and the unit block assembly are separated from the sea by adjusting the buoyancy of the unit block assembly and the buoyancy of the launching bar so that the launching pants are partially submerged and the unit block assembly is floated;

A sixth step of adjusting the buoyancy of the launching pants to float; And

A seventh step of inserting a side wall block into the space to complete the second pants, and connecting and assembling the first pants formed of the unit block assembly in line with the second pants;

It is a method of drying the dried poison containing.

According to the present invention, it is possible to reduce the cost incurred by the use of the equipment by minimizing the use of expensive equipment required for drying the cultured poison, and it is applicable at sea without having to secure a separate poison for drying the cultured poison Since most of the farmed dock can be dried, the overall manufacturing cost for drying the farmed dock can be reduced.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 and 5 to 11 is a perspective view schematically showing the drying process by the buoyant poison drying method according to the present invention bar, will be described with reference to this.

1. In a buoyant poison drying method for drying by connecting the unit block 200, which is capable of supporting the sea, the first step of launching the bottom block (110, 110 ') constituting the unit block 200 ;

According to the present invention, a method of drying a cultured dock is to manufacture a unit block 200, which is a basic structure for manufacturing a farmed dock (FD; see FIG. 11), on the ground 10, and the completed unit block 200 is marine. It is launched using a crane 30 to float on the sea (20). (See Fig. 1 and 2) In this case, the unit block 200 is composed of a bottom block (110, 110 ') and side wall block 120 The launching through the crane 30, the bottom block (110, 110 ') is made preferentially.

On the other hand, since the marine crane 30 is a device that must pay a relatively high fee for use (including operating costs and management costs), all of the unit block 200 constituting the floating dock (FD) offshore 10 ( 20) can be unreasonably expensive. Therefore, in the method of drying the buoyant poison according to the present invention by manufacturing only the minimum floor blocks (110, 110 ') that is the basis of the buoyant poison (FD) in the ground (10) and then transported to the sea (20), It is possible to reduce the cost incurred by the use (rental) of the crane (30).

2. a second step of fabricating the floor blocks assembly (a) by assembling the launched floor blocks (110, 110 ');

When the bottom blocks 110 and 110 'are transported to and lifted by the offshore crane 30 by the offshore crane 30, the respective floor blocks 110 and 110' are connected to each other to form a huge plate-shaped bottom block assembly (a; pontoon) (see FIG. 3).

For reference, the unit block 200 according to the present invention is a plurality of dogs are connected in a line to form a huge floating dock (FD), for this purpose, the bottom block (110, 110 ') in direct contact with the water and the floor block ( It consists of side wall blocks 120 which are placed on both sides of the 110, 110 '. On the other hand, a plurality of tanks (not shown) are built in the bottom blocks 110 and 110 ', a pump (not shown) forcing the inflow and outflow of seawater into the tank, and a control system for controlling the pump (not shown) Is installed on the side wall block 120. Pants 100 having the above-described structure is a well-known fact in the art of the floating dock (FD), and thus detailed description of the structure and configuration of the pants 100 will be omitted.

Figure 4 is a partial side cross-sectional view schematically showing the connection of the pants used in the method of drying the poisonous poison according to the present invention, it will be described with reference to this.

Since the connection between the bottom block 110 and the bottom block 110 'requires the robustness and waterproofness of the connection portion, the connection portion is tightly coupled by welding. On the other hand, in order to accurately connect the neighboring floor blocks (110, 110 ') by placing the guide 115 in each connection of the floor blocks (110, 110'), even in the sea 20 floor blocks (110, 110) ') So that the connection between them can be made precisely. In the embodiment according to the present invention, the guide 115 is disposed on the upper portions 112 and 112 ′ of the floor blocks 110 and 110 ′ which are open to the sea 20.

On the other hand, the bottom block (110, 110 ') has a lower portion (111, 111') that is submerged while being disposed on the bottom of the upper (112, 112 '). The lower portions 111 and 111 'together with the upper portions 112 and 112' form a waterproof structure to increase the waterproofness of the neighboring bottom blocks 110 and 110 '.

An embodiment of the waterproof structure according to the present invention includes a packing member 113 and the protrusion 114. The packing member 113 is installed at the bottom 111 of the arbitrary bottom block 110, and correspondingly, the protrusion 114 is installed at the bottom 111 'of the other bottom block 110'. As a result, when the bottom blocks 110 and 110 ′ come into contact with each other, the protrusion 114 contacts the packing member 113 with pressure, as shown in FIG. ') And the entrance to the space surrounded by the upper (112, 112') can be blocked.

In the above-described manner and structure, the bottom block assembly (a) to which the bottom blocks 110 and 110 'are connected is floated on the sea 20 as shown in FIG.

3. A sidewall block 120 having a control system for controlling the buoyancy of the floorblock assembly (a) is placed side by side symmetrically along both edges of the floorblock assembly (a), wherein the top surface of the bottomblock assembly (a) is at one end. A third step in which the sidewall block 120 is placed only at the other end of the bottom block assembly a so as to form the space a1 open to the side;

Subsequently, the sidewall block 120 is installed at the edge of the bottom block assembly a to form the launching pants b. The side wall block 120 is to control the front and rear surfaces of the floating form dock (FD) to the shape of, the control to control the pump that can flow in and out of the seawater to the tank installed in the bottom block (110, 110 ') The system is built. In addition, an operation system for operating and operating equipment, such as a crane (not shown) installed in the completed floating form dock (FD), etc. is incorporated (see FIG. 5).

In this case, as shown in FIG. 6, the sidewall blocks 120 are symmetrically disposed along both edges of the bottom blocks 110 and 110 ′, so that the bottom block assembly a can rise horizontally without tilting. Make sure

Meanwhile, since the front and rear surfaces of the floating dock FD must have a 凹 shape, the completed docked dock FD should be provided with sidewall blocks 120 for each bottom block 110 and 110 ′. However, the method for drying the buoyant poison according to the present invention is to be able to dry the entire buoyant poison (FD) directly in the sea (20), the unit block further connected to the previously manufactured floor block assembly (a) A space a1 for accommodating the 200 should be secured. Therefore, in order to secure the space a1, the side wall block 120 is installed only in a part of the bottom block assembly a.

As a result, the floor blocks 110 and 110 ′, in which the side wall blocks 120 are not installed, secure open spaces a1 that are not limited in the horizontal direction on the upper surface, so that the unit block 200 of the launching pants b is installed. It can be seated on space a1.

For reference, in order to install the side wall blocks 120 on the bottom blocks 110 and 110 ′, the land crane 40 may be used as shown in FIG. 5. Here, the land crane 40 is significantly lower than the offshore crane 30, so the cost of installing the side wall block 120 can be reduced.

4. Place the bottom block assembly a so that the space a1 faces the ground 10, transfer the unit block 200 to the space a1, and connect the plurality of unit blocks 200 at sea. A fourth step of manufacturing a unit block assembly (c, c ');

The launching pants b thus manufactured are arranged such that the space a1 faces the ground 10 as shown in FIG. 6. At this time, the protruding height of the floor blocks 110 and 110 ′ floating on the sea 20 is the same as the height difference between the ground 10 and the sea 20 so that the top surface of the ground 10 and the space a1 is the same. Place it on a similar height line.

When the launching pants b are arranged as shown in FIG. 6, a rail (not shown) is installed to transfer the unit block 200 to the space a1. As described above, the rail is used to transfer the unit block 200 to the space a1 of the launching pants b so that the rail installed on the space a1 and the rail installed on the ground 10 are connected to each other. .

As a result, the unit blocks 200 manufactured on the ground 10 are moved along the rails and transferred into the space a1 of the launching pants b. In this manner, the unit blocks 200 are arranged in a row. As shown in FIG. 7, the unit block 200 is manufactured by connecting the unit blocks 200 on the space a1.

On the other hand, the mechanical connection between the unit block 200 and the telecommunication connection work is carried out in the space (a1), it is possible to obtain the same effect as performing the work on the ground (10), the launching pants (b) production For the purpose of supporting the bottom block (110, 110 ') in the offshore 20 other than the offshore crane 30 is not used, so the manufacturing cost can be significantly reduced.

5. The launching pants (b) are partially submerged and the unit block assemblies (c, c ') are floated so that the buoyancy of the unit block assemblies (c, c') and the buoyancy of the launching pants (b) are adjusted so that the launching pants ( b) a fifth step of separating the unit block assembly (c, c ') from the sea;

Subsequently, when the connection operation of the unit block 200 is completed and the unit block assembly (c, c ') is manufactured, it is separated from the launching pants (b) and floated on the sea 20, the launching pants separated in this way (b) and the unit block assembly (c, c ') in a row. To this end, the launching pants (b) and the unit block assemblies (c, c ') must be separated from each other, which submerges the launching pants (b) to a certain depth, and the unit block assemblies (c, c') are relatively floating. Possible (see Figure 8).

In more detail, when the launching pants (b) are submerged while the unit block assemblies (c, c ') are provided in the space (a1), the unit block assemblies (c, c') are lowered together with the sea ( 20) is in contact with the water surface. At this time, by operating the pump in the side wall block of the unit block 200 constituting the unit block assembly (c, c ') to flow air into the tank provided in the unit block 200, unit block assembly (c, c') The buoyancy is formed in the launching pants (b) even if the deep diving unit block assembly (c, c ') is not submerged any more to maintain a constant degree of floating.

6. a sixth step of adjusting the buoyancy of the launching pants (b) to rise;

The launching pants (b) and the unit block assemblies (c, c ') separated vertically by the buoyancy difference are moved to a traction line (not shown), and the partially submerged launching pants (b) are adjusted to adjust the buoyancy. Let's do it.

7. Insert the side wall block 120 into the space a1 to complete the second pants B, and connect the first pants A composed of the unit block assemblies c and c 'with the second pants B. A seventh step of assembling and assembling in a row;

The first pants A composed of the unit block assemblies c and c 'and the second pants B formed by installing the sidewall blocks 120 on the launching pants b are arranged in a row. 11)

Two or more unit block assemblies (c, c ') are connected in a row to form a first pants (A) corresponding to the second pants (B), the first and second pants (A, B) thus completed is It is again lined up to form a floating poison (FD).

In this case, as the unit block assemblies (c, c ') are manufactured as many times as the fourth to sixth steps are repeated, the scale of the first pants (A) may be increased.

Thus completed first pants (A) and second pants (B) by applying the connection structure (see Fig. 4) between the above-described floor blocks (110, 110 '), can achieve a tight and high waterproof rate fastening have.
