Description

[0001] Floating dock and method for manufacturing caisson using same [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating dock and a method of manufacturing a caisson using the same. More particularly, the present invention relates to a floating dock, , It is possible to reduce the air and cost due to the construction of the work stage, and in particular to prevent damage or breakage of the floating dock itself, thereby facilitating the operation of the floating dock, while also facilitating the operation of a large structure such as a cassette It is easy to construct and make the caisson directly from the dock, thus eliminating difficulties such as securing the existing site or transporting it separately, and ultimately reducing the manufacturing air of the caisson and reducing the cost, and the caisson And a manufacturing method thereof.

The known caisson is a (large) concrete structure made in the form of a box, which is generally used to build important facilities for harbors and bridge structures such as breakwaters, gravity walls and bridges.

Such a caisson is a precast reinforced concrete member and can withstand a strong earth pressure and is usually used on land because its quality is easy to manage and inexpensive fillers can be obtained.

On the other hand, such a caisson construction has a method of constructing a temporary dock, constructing a caisson, introducing seawater into a temporary dock, disassembling the water barrier, and launching the water barrier.

In this case, since the caisson is produced on the ground, it is possible to make a very large caisson, and it is advantageous that the caisson making function is minimized by enlarging the caisson and there is no need to construct a separate production site.

However, there is a problem that a large site equipped with a provisional dock should be premised, and it is affected by maritime conditions at the time of launching and transporting, and there is a problem that a separate equipment or considerable manpower and time are required for transportation.

The dock is divided into a dry dock and a floating dock. The floating dock is a maritime structure including a ballast tank in the dock. The floating dock sinks into the water, and when the water is discharged from the ballast tank, the floating dock floats in the sea.

However, another way of making a caisson is to make a caisson using a dry dock of a shipyard and launch it on the sea.

For example, when a caisson is manufactured from an empty dock of an existing shipyard, and the caisson is completed, the interior of the empty dock is opened and the gate is opened.

This method is advantageous in that it makes it possible to launch a large caisson as in the case of making a caisson in a temporary dock, minimizes the manufacturing function by enlarging the caisson, and does not need to construct a separate production site unlike the temporary dock.

However, there should be a large empty dock at the shipyard, a work space related to the production of caissons must be secured, and the maritime conditions of launching and transportation will be affected. In addition, Time is needed.

Meanwhile, in recent years, a method of manufacturing a caisson using a floating dock (FD) has been known. For example, a caisson is formed on the ground, and the caisson is transported using a floating dock.

In other words, the caisson is installed near the sea, and the caisson after the caisson is prepared is transported to the installation place by the floating dock.

But. The method of constructing the caisson from the ground and transporting it to the floating dock requires the establishment of a site for the caisson, the additional cost of constructing the additional facility, and the accessibility with the caisson installation site There is a problem that considerable time and cost are incurred in securing separate sites each time a caisson is manufactured.

In particular, since large caissons are considerable heavyweight in themselves, considerable time and sophistication is required to move and mount them in a floating dock, leading to construction costs and air delays.

Therefore, in recent years, a method has been known in which caissons are directly made on a floating dock prepared on the sea, and various problems described above, that is, various problems caused by temporary docking, empty docking of a shipbuilding ship, or manufacturing on the ground are solved.

That is, when a caisson is directly manufactured on a float-type dock in the sea, it is easy to move or launch to a desired place, and as a result, costs and air can be shortened.

For example, Korean Patent Laid-Open No. 10-2011-0134559 proposes a technique for manufacturing a caisson using a floating caisson production site.

That is, in the above-mentioned patent, when a floating structure (float type dock) floats in the sea when the caisson is manufactured, if the caisson is removed in order to eliminate the difficulty in manufacturing due to the wave or the like, We propose a technique to connect and fix.

However, in the case of the above-mentioned patent, the caisson is constructed on the deck of the floating type dock, that is, the deck of the view dock type dock. However, since the caisson is directly manufactured without a separate operation stage on the dock deck, The cost of maintenance and maintenance of the floating dock due to the construction of the caisson is considerably high and the floating dock can not be put into the construction or transportation of the dock immediately after completion of the production of the caisson, And the problem of costly damages arises.

That is, no technique has been proposed for constructing a separate work stage for protecting the dock when manufacturing a caisson in a conventional floating dock.

Therefore, in the related art, a separate work stage is constructed on the floating dock, and the work stage can be easily constructed in various forms, so that it is possible to reduce air and cost due to the construction of the work stage, It is possible to facilitate the operation of the floating dock while facilitating the construction of a large structure such as a cassette on a work stage and to make the caisson directly from the dock, There has been a demand for a floating dock capable of shortening the production air of the caisson and reducing the cost and a method of manufacturing a caisson using the dock.

Technical Solution [10] In order to achieve the above-mentioned object, the present invention provides a dock comprising: a dock main body; And a work stage provided with a height on the dock main body portion,
The work stage includes a plurality of rail members provided on the dock main body portion, a plurality of column elements assembled to the rail member, And a work stage bottom plate mounted on the column element,
And a second rail member provided on the work stage bottom plate to assemble the column element.

Further, the embodiments of the present invention are provided to more fully explain the present invention to those skilled in the art. (The shape and size of elements in the drawings may be exaggerated for clarity.)

First, the present invention relates to making a caisson using a floating dock.

For example, a conventional floating dock for making a caisson used in the manufacture of a caisson in Korea is only about 70 m in length. Therefore, the function of a caisson that can be made in a unit floating dock is a very limited problem.

However, in a large floating dock (FD), for example, ships such as LNG carriers, container carriers, or Ro-Ro carriers are being dried.

Therefore, in the case of the present invention, instead of using a small floating dock, it is preferable to increase the function when a caisson is manufactured in a large floating dock having a length of about 200 m or more for ship drying-repairing.

That is, in the case of the present invention, caissons are manufactured directly from a large floating dock, and a separate operation stage is constructed on the floating dock as described in detail below, so that the floating dock itself is not damaged or damaged I will not.

In the case of the floating dock of the present invention having such a work stage, dock breakage or the like is prevented by the work stage, and the work stage itself is adjusted to have a height difference appropriate for the caisson manufacturing, , Seawater can be circulated to the lower part of the work stage, and problems such as blue can be solved.

Of course, it is needless to say that the floating dock and the working stage of the present invention, which will be described in detail below, are not necessarily limited to a large floating dock for ship drying / repair.

That is, the work stage of the present invention, which will be described in detail below, has no problem in its construction and use, regardless of the size of the floating dock.

There is also no problem in connecting the small floating docks to increase the length of the dock and to construct the work stage of the present invention.

Accordingly, the floating dock according to the present invention and a method for manufacturing a caisson using the same will be described in detail below.

First, the floating dock 1 of the present invention, shown and described in FIGS. 1 to 10, basically includes the work stages 100, 200, and 300 of the first to third embodiments.

For example, Figures 1 and 2 illustrate a floating dock including the work stage 100 of the first embodiment, and Figures 3-7 illustrate the work stage 200 of the second embodiment and variants thereof And finally a floating dock including the work stage 300 of the third embodiment is shown in FIGS. 8-10. FIG.

On the other hand, the floating dock 1 of the present invention including the work stages 100, 200, and 300 of the first through third embodiments of FIGS. 1, 2, and 3, 4, It may be provided in a structure in which the upper end portion 50 is assembled between the vertical wall portion 30 and the vertical wall portion vertically mounted on the dock main body portion 10 floating on the sea surface.

A crane 70 'and an office structure 52 may be mounted on the upper portion 50.

The upper part 50 may be provided with a driving facility 70 for an anchor 72 to prevent floating dock from flowing on the sea surface in the course of making a caisson (not shown) in the floating dock have.

Of course, although not shown in the drawings, the basic structure (main body portion, vertical wall portion, and upper end portion) of the floating dock of the present invention can be changed.

In the floating dock of the present invention, at least the main body 10 may be provided with ballast tanks (not shown) for controlling flooding and floating of the dock.

Therefore, when the caisson is manufactured in the floating dock 1 of the present invention, the dock can be submerged and the launch of the caisson can be immediately realized in the field.

Although not specifically shown in the drawings, the floating dock 1 of the present invention is preferably a large floating dock for drying and repairing a ship having a length of 200 m or more as described above, Shown and described as a single dock.

Of course, there is no problem in connecting small docks to provide a large floating dock such as the float dock of the present invention.

Hereinafter, the operation stages 100, 200, and 300 of the first to third embodiments of the floating dock 1 according to the present invention will be described.

However, in the following description of this embodiment, the operation stages of the first to third embodiments will be briefly described as the first to third operation stages 100, 200, and 300. FIG.

1 and 2, a view oil feed type dock 1 according to the present invention includes a dock main body 10 and a first operation stage provided with a height on the dock main body 10, (100).

The first work stage 100 of the present invention includes a plurality of column elements 110 provided on the dock main body portion 10 and a work stage bottom plate 130 That is, as a steel plate structure.

In addition, although the bottom plate is not divided into different reference numerals in the drawings, it may be a structure in which unit steel plates having a thickness are firmly connected to each other through welding, iron joining, or the like.

1 and 2, the column element 110 of the present invention may be a pipe structure having an appropriate strength, and such a pipe structure may be formed on the deck 12 of the dock main body portion 10 And the lower end may be provided by welding.

Alternatively, although not specifically shown in Figs. 1 and 2, if the column element has a separate flange or supporting plate (see the supporting plates 232 and 272 in Fig. 5) or the like, the bolts, ). ≪ / RTI >

The bottom plates 130 having a thickness to be covered by the upper end of the column element are welded to the pipe structure of the column element or welded to each other by using bolts, It can be firmly fixed.

In this case, although not separately shown in the drawing, it is possible to provide the work stage bottom plate 130 having a height difference by making the height of the column elements different in the first work stage 100 of the present invention. In this case, It will be possible to use variously.

1, a structure 500 for manufacturing a structure, for example, a mold structure 510 for manufacturing a caisson, may be installed on the bottom plate 130 of the first operation stage 100 have.

The mold structure 510 of the facility may be firmly fixed to the bottom plate 130 of the first operation stage 100 by the fixing structure 530 or the like.

That is, in the case of the first working stage 100 of the present invention and the second working stage 200 described in detail with reference to FIGS. 3 to 7, since the lower space of the bottom plates 130 and 250 is formed, The connection and fixing operation of the fixing structure 530 for supporting the formwork structure 510 can be facilitated and diversified.

For example, even if welding is performed on the bottom plate, the replacement of only the portion is easier than the deck 12 of the dock in the case of the working stage of the present invention, so that the docking of the installation facility 50, such as a caisson, .

Accordingly, as shown in FIGS. 1 and 2, when the concrete structure 510 of the facility 500 is filled with concrete and cured, a caisson (not shown) of a desired shape can be constructed.

Of course, the main body portion 10 and the vertical wall portion 30 of the floating dock, such as concrete / remicon supplying equipment, associated storage tanks, oil, pneumatic system, And the like.

However, the floating dock of the present invention floats on the sea surface adjacent to the coast to exclude the dock transportation of existing caissons, and there is no problem in that equipment such as electric cables are connected to the floating dock from the ground to make a caisson .

Therefore, since the floating dock 1 of the present invention includes the first work stage 100 as well as the second and third work stages 200 and 300 which will be described in detail next, Or block can partially cover the deck 12 and the vertical wall portion 30 of the dock main body portion 10 so that damage or breakage of the dock main body portion or the vertical wall portion can be effectively prevented when the caisson is manufactured.

And, since the height of the bottom plate of the work stages can be easily adjusted by using the height difference of the column elements or blocks, it is advantageous over the deck 12 of the existing dock without height difference in terms of the space utilization of the work stage.

In the case of the first working stage 100 shown in FIGS. 1 and 2, the dimensions of the column element 110 and the bottom plate 130 are determined according to the size of the caisson, that is, the total load of the caisson (Strength) and spacing in consideration of the above-mentioned requirements.

The bottom plate 130 may have a double iron plate structure and may have a plurality of connection hardware or bolt holes for constructing the mold structures 510 of the facility 500 although not shown in detail in the drawing.

Therefore, the view oil type dock 1 of the present invention can construct the bottom plate 130 of the work stage 100 having a height on the deck 12 instead of the deck 12 of the flat dock body portion 10 It is possible to provide a considerable work convenience, such as a change in the bottom plate, formation of a height difference, arrangement of other related apparatuses, and so on.

As shown in FIGS. 1 and 2, since a space is formed in the first work stage 100 by the height of the column elements 110, and thus seawater flows through this space, So that the flow of the dock does not occur.

3 through 7 illustrate a second work stage 200 according to the present invention.

3 and 4, the second work stage 200 of the present invention includes a plurality of rail members 210 provided on the dock body portion 10, A plurality of column elements 230 assembled at a suitable location while being mounted on the column elements 230, and a work stage bottom plate 250 constructed on the column elements 230.

Further preferably, the second rail member 270 is assembled to the bottom of the work stage bottom plate 250 while moving the upper end of the column element 230.

3 and 4, the second work stage 200 of the present invention is constructed such that the rail members 210 and 270 are connected to the deck 12 of the dock body portion 10 and the work stage bottom plate 250, Which are spaced apart from each other at the bottom of the rail elements, so that the column elements 230 can be conveniently located at desired points as they move between the rail elements.

At this time, at the time of actual construction, the first rail member 210 is installed on the dock deck 12, the column members 230 are easily moved along the rail members, and the bottom plate 250 is seated thereon It is also possible to join by welding or by bolting.

Alternatively, the work stage bottom plate 250 may be pre-loaded with the second rail members 270 at a lower level and provided on the dock 250 on the dock to facilitate the movement of the column element 250 It is also possible.

Alternatively, it may be possible to construct the work stage 200 by associating a bottom plate on some column elements and then arranging the column elements along the rail elements.

Accordingly, in the case of the second work stage 200 including the rail member of the present invention, various forms of construction can be provided.

That is, the rail members 210 and 270 integrally join (join) the deck 12 of the dock main body 10 and the bottom plate 250 of the second work stage 200 at appropriate intervals in the direction of the dock length, It is possible to enhance the structural strength of the work stage and, above all, to facilitate the construction of the column elements, as compared with the construction of the bottom plate with only the column elements as shown in Figs.

Of course, as shown in FIGS. 3 and 4, the seawater can flow into the space formed at the bottom of the bottom plate 250 due to the height of the column elements 230.

That is, in the second working stage 200 of the present invention, the rail members 210 are arranged at suitable intervals on the deck 12 of the dock main body 10 and fixed with welding W, bolts B, When the column element is assembled to the rail member at a desired position while the column element 230, that is, the pipe structure or the like, is simply moved along the rail member 210, the installation of the column elements is completed. Work will also be easy.

Next, like the ratio shown in Fig. The lower end portion and the upper end portion of the column element 230 are received and supported by the rail member 210 on the deck 12 side of the dock main body portion 10 and the second rail member 270 on the bottom side of the bottom plate 250 And may further include a support plate 232.

At this time, the rail members 210 and 270 may further include flanges 232 and 272, which are supported by support plates 232 integrally or welded to the lower and upper ends of the column elements.

Accordingly, when the pillar element 230 is pulled from one side of the rail members 210 and 270 due to the upper and lower support plates 232, the pillar element 230 can be moved along the rail member of the pillar element, Will make the structure more robust.

As a result, since the second operation stage 200 of the present invention is easy to install the column elements, when the caisson manufactured by the large floating dock 1 for shipbuilding-repairing is more than 200 meters, In order to support the working stage, a considerable number of column elements are required, although schematically shown in the figure, so that in the case of the second working stage 200 of the present invention, the rail members 210, And can be a rigid structure fixed with an area on the plate, thereby reinforcing the strength of the entire work stage.

5, the rail members 210 and 270 are welded (W) to the deck 12 of the dock main body 10, or jointed hardware 214 (see FIG. 5) provided integrally or welded on one side 274 may be fastened to the deck 12 (steel plate) or the bottom plate 250 of the dock main body to provide a rail member.

In this case, for ease of understanding, various assembly forms of the rail member are shown in FIG. 5 in one drawing.

A bolt B passing through the flange 212 of the rail member 210 fixed to the deck 12 of the dock main body portion 10 is fastened to the support plate 232 of the pillar element 230, Can be achieved.

Alternatively, the bolt B is passed through the flange of the rail member and the support plate of the column element 230, and the bolt B is fastened to the deck 12 and the bottom plate 250 of the dock main body portion 10, It is also possible to assemble.

5, when the bolt B passing through the bracket 274 of the upper rail member 270 passes through the bottom plate 250 and is fastened as a nut, A fixture 550 to which a fixture structure 530 (wire or the like) connected to the construction equipment 500 for forming a caisson, that is, the mold structure 510 shown in FIG. 1, may be coupled and used.

Therefore, as shown in FIGS. 3 to 5, when the bolts passing through the rail member and the bottom plate of the present invention are appropriately used, the caisson construction through connection with the facility will be facilitated.

6 and 7 show another modified example of the second work stage of the present invention using the rail member. For example, the rail member 210 and the bottom plate side are provided on the deck side of the dock main body portion 10, The elongated holes 214 and 274 are formed in the second rail member 270 of the flange 212 and the flange 212 of FIG. To adjust.

Accordingly, when the support plate is rectangular, the column member 230 is moved along the rail member such that the narrow surface is the front surface, and when the long holes 214 and 274 formed in the rail members 210 and 270 are positioned, The column element 230 is rotated by about 90 degrees, and at this time, the rectangular column element support plate 232 can be inserted into the slot of the rail member and fixed in position.

6 and 7, the support plate 232 of the column element 230 moves along the inner space of the rail members 210 and 270 and reaches the position of the slots 214 and 274 Since the lower column element is rotated by 90 degrees and the support plate is inserted into the elongated hole of the rail member, there is no need to grasp the assembling position of the column element separately and the supporting plate is inserted into the slot. It will be solid.

6 and 7, the bolts B are fastened between the support plate 232 and the rail members 210 and 270, and the rail members are welded or bolted with separate brackets, Can be fixed to deck or bottom plate.

When the bolts B passing through the support plate and the rail member are fastened to the deck 12 and the bottom plate 250 of the dock body part, Can be completed.

5 to 7, 'W' represents a welded portion. As described above, in FIGS. 5 to 7, the fastening structure of the bolt is shown differently so that the assembling structure is easily understood.

If the arrangement of the long holes of the rail member is made appropriate, the position of the long holes becomes the assembling position of the column elements, so that the construction of the column elements will be convenient.

For example, when the number of column elements is determined according to the manufacturing standard of the case, the number and position of the slots may be adjusted in the rail member.

8-10 illustrate a third work stage 300 according to the present invention.

8 to 9, in the third working stage 300 of the present invention, the box-shaped unit blocks 310 are assembled with each other on the deck 12 of the dock main body portion 10 And is provided as a block assembling type work stage to be mounted and fixed.

For example, as shown in FIGS. 8 and 9, the unit blocks 310 of the present invention may be provided on the dock body portion 10 with suitable heat. Particularly, when one unit block of the present invention is placed on the deck of the dock main body part, the following unit block is closely assembled to the preceding unit block and the next unit block 310 You can assemble it.

10, in the case of the block assembly type work stage 300 of the present invention, the unit block 310 includes an assembling groove portion 330 into which the assembling protrusion of the adjacent unit block is inserted, And the assembling protrusion 320 inserted in the assembling groove is provided in a predetermined pattern.

The assembling protrusion 310 can be assembled to the deck 12 of the dock main body part in Fig. 9 using a crane (70 ' in Figs. 1 and 3) provided in the floating dock 1, The rear unit blocks 310 are sequentially placed in correspondence with the positions of the assembling protrusions 320 and the assembling recesses 330. When the assembling protrusions 310 are mounted on the dock main body 310 10 on the deck.

At this time. Preferably, the third work stage 300 of the present invention does not use column elements such as the first and second work stages, so that the unit blocks 310 are provided with seawater And a seawater passage 350 through which the water passes.

However, it goes without saying that the penetration direction of the seawater passage opening 350 is adjusted in advance so as to communicate with each other in the longitudinal direction of the dock when the unit blocks are assembled as shown in FIG.

Meanwhile, the unit blocks 310 of the third operation stage of the present invention may be provided with steel plates formed in the form of a box on the basis of beams, sections, etc., and the assembly projections 320 may be provided by welding And can be integrally provided.

9, the unit block 310 may be provided as a suitable row on the deck 12 of the dock main body 10, but the unit block X adjacent to the vertical wall portion 30 may be provided as a unit block, And the center side unit blocks may be provided with staggered projecting portions 310 in a staggered manner on both sides of the central unit side blocks, and adjacent unit blocks on the adjacent vertical wall side may be provided on only one side, The unit blocks 320 may be prepared in advance and arranged in a combination fashion.

Preferably, as shown in FIG. 9, the assembling protrusion 320 of the unit block 310 and the assembling groove 330 are disposed to be shifted from each other.

Therefore, since the third work stage 300 of the present invention shown in FIGS. 8 and 9 is constructed as a blocked work stage, the first and second work stages 100 and 200 of the present invention On the other hand, there is a portion for preparing unit blocks in advance, but since it is possible to construct the work stage on the deck of the actual floating dock more quickly, if the blocks are prepared in advance, It may be more advantageous to construct a third work stage.

9, in the case of the third work stage 300 constructed by combining the unit blocks 310, the elastic force of the unit block is applied between the vertical wall 30 and the adjacent unit block, It is also preferable to interpose an elastic plate 370 for preventing the flow of the fluid.

Although not shown in the drawings, the unit blocks may be fixed on the deck 12 of the dock main body part 10 by means of bolts through welding or welding.

As shown in FIG. 10, the unit block 310 may be provided with the assembling protrusion 320 and the assembling recess 330 in four directions. Therefore, the unit blocks are structured so as to be very firmly blocked.

Therefore, in the case of using the floating dock of the present invention described so far, the caisson curing facilities (first to third working stages 100, 200 and 300) of the present invention provided in the floating dock 1 500), and a method of fabricating a caisson using the floating dock, which is a step of curing the caisson using the facility 500.
