Description

[0001] MODULAR REVETMENT STRUCTURE AND CONSTRUCTION METHOD [0002]

The present invention relates to a modular hoist structure and a method of construction thereof. More specifically, the present invention relates to a modular boating structure for constructing a boating structure by using a caisson, and dividing the caisson into a bottom plate, a middle plate, and an upper level module,

Caisson used in large port construction or shore protection construction is a large box type structure, and its weight is generally from several hundred tons to several thousand tons.

Therefore, the caisson is made in advance in the caisson manufacturing site, and the caisson is carried by the buoyant by using a bogie to carry the caisson to the launching spot, And the buoyancy is installed through the process of towing to the place where the boat is placed and putting it in place.

FIG. 1A shows a conventional caisson launching method using a conventional buoyant barge.

That is, after the caisson 10 having the buoyancy brackets attached thereto is moved from the caisson manufacturing site to the platforms provided in the launching platform 30, the platform 10 is moved to the caisson 10 ).

Next, water is filled into the buoyancy barge 50 formed by the both-end vertical portions so that the launching caisson 10 is positioned inside, and the buoyancy bracket of the caisson is towed to the place where the caisson is located, As shown in FIG.

Next, the caisson is floated in the buoyancy barge with the buoyancy generated by emptying the water filled in the buoyancy barge 50,

The buoyancy barge integrated with the final caisson is towed to a predetermined position and then the straight line of the buoyancy bar is filled with water so that the caisson 10 is separated from the buoyancy barge 50 and seated.

Therefore, it is advantageous to use the buoyancy of the caisson, which is a large box-type structure, but economical efficiency can not help because the buoyancy barge (50) needs to be separately provided.

A method of floating a caisson by a crane mounted on a barge at sea without using a buoyancy barge (50) is also disclosed.

In other words, in order to construct a marine hull structure to be used for marine landfill or breakwater, several large caissons manufactured on land are loaded on a barge and a simple crane is mounted in the longitudinal direction from the sea .

At this time, the conventional marine hull structure is designed so that only the caissons that are overloaded (actuated) and transferred (overheated) when a typhoon or a tsuno that exceeds the design load are prevented from connecting (interlocking) .

This design concept has the advantage of replacing only the specific block where problems (activity or conduction) occurred during the reinforcement of the caisson maintenance.

However, since the caissons of the revetment structure lengthened in the longitudinal direction are not connected to each other, that is, the interlocking effect does not occur and the adjacent caissons act separately,

In case of typhoon or tsunami, the maritime rescue structures were not able to effectively resist wave loads and were easily pushed or turned.

In addition, since each caisson must support the wave load only by the force of gravity, each caisson member constituting the revetment structure must be heavy to secure a sufficient weight, and therefore, it is necessary to use a large- Which is a major factor for increasing the cost of marine construction.

As shown in FIG. 1B, FIG. 1C, FIG. 1D and FIG. 1E, the concept of a variety of interlocking revetment structures of cable type, key block type, concavo-convex type, and filler type has been proposed in order to solve the problems of the conventional marine revetment structure.

The conventional large caisson is physically coupled in the longitudinal direction so that the interlocking effect due to the coupling is not large.

Also, in these conventional methods, since the existing large caisson is applied as it is, it is necessary to use a large-sized marine crane, so that the marine construction cost has not been greatly improved.

Korean Patent Laid-Open No. 10-2015-0144981 (title of invention: offshore plant module system and method for installing offshore plant module in coastal waters) Korean Utility Model Registration No. 20-0357965 (Title of the invention: caisson provided with supporting means)

Accordingly, the present invention can be applied to a case in which the above-mentioned conventional caisson is divided and manufactured in a modular manner, mounted on a divided barge line, and assembled and mounted using a smaller capacity crane at a position where the caisson is to be installed, And to provide a modular hoist structure and a construction method thereof.

In addition, the assembled and mounted caissons can interlock with each other to ensure sufficient longitudinal stiffness in the longitudinal direction (longitudinal direction) and vertical direction, thereby minimizing the longitudinal movement and providing a safer modular hull structure and its construction The present invention has been made in view of the above problems.

Further, the above-mentioned assembled and mounted caisson does not mount the large caisson itself, minimizing construction equipment, and providing a modular revetment structure having excellent workability and workability, and a method of constructing the same.

As a result, the bottom plate module 110, the intermediate module 120, and the top plate module 130 are interlocked with each other in the longitudinal direction to be integrated with each other, and are integrally assembled and assembled together in the vertical direction.

3C, when the modular boom structure 100 is assembled and mounted on the bottom plate module 110, the intermediate module 120, and the topsoil module 130, The middle plate 120, and the top plate module 130 can be easily assembled and fixed while serving as a fixing point for the bottom plate module 110, the intermediate module 120, and the top plate module 130, as a guide structure.

The columnar key block 140 is configured to include a bottom plate 141, an inner wall 142, and both outer walls 143, for example, as a retaining wall structure.

The bottom plate 141 is a plate-shaped member extending in the transverse direction, and an inner wall 142 in the form of a vertical plate spaced longitudinally from each other is formed on the top surface of the bottom plate 141

And the outer wall 143 formed on the upper surface of the bottom plate as a vertical plate-like member extending in the longitudinal direction on the vertical back surface of the inner wall 142.

The inner wall 142 is spaced longitudinally from one another on one side of the outer wall 143 so that the ends of the modular revetment structure 100 assembled and fixed on both ends are inserted and fixed. As the length of the revetment structure 100 becomes longer, it serves as a guide structure while complementing longitudinal connection rigidity with a structure serving as a fixed point in the middle.

In other words, since the ends of the modular hull structure 100 are supported by the pillar-shaped key block 140, the modular hull structure 100 can be more stable as a fixing point and serves as a guide member.

In this case, the meaning of the column shape is the shape corresponding to the entire height of the modular boating structure 100 and can be said to be constructed as an intermediate pillar member.
