The present invention relates to a temporary barrier structure using buoyancy and self-weight and a new structure and reinforcement method using the same. More specifically, for the repair, reinforcement and partial new construction work under the condition that the hydraulic structure such as drainage lock and the bottom surface or side retaining wall continuously formed under the repair structure are continuously receiving water pressure by sea water or fresh water. When a water blocking process is required, temporary water blocking structures are installed to partially dry the box-shaped temporary water blocking structures on the hydraulic pressure side of the repair structure, and to enhance the safety of the installation and the efficiency of dismantling work. To prevent the hydraulic pressure acting on the hydraulic pressure surface from being transmitted to the surface of the hydraulic pressure, it does not threaten the structural safety of the repair structure. It is about a method of making and constructing a temporary temporary barrier structure. All.

Applicant of the present invention has already applied for a temporary clasp structure related to the present invention (Patent Application No. 71383, Utility Model Registration No. 308924).

The preliminary temporary cladding structure is applied to the order means such as the sheet pile method that is commonly used in order to ensure the required dry work (Dry Work) environment that is the most important problem in the repair work of repair structures such as drainage lock It is to solve the problems (delay of working air, inefficiency of workability, impossibility of recycling and increase of construction cost by using large equipment) in construction, and because there is always water pressure surface because it is in contact with seawater or fresh water Hydraulically or self-weighting the end of the hydraulic structure or the supporting structure formed on the hydraulic surface or the repair structure itself, while wrapping the portion of the hydraulic structure to be repaired and reinforced with a minimum size, so that it can be used for work such as repair of the structural structure. It is installed so as to be in contact with, by forming an index means at the end in duplicate The upper and lower parts are installed with reinforcement means for supporting the water pressure by seawater or fresh water and the separation prevention means for securing the safety of work by detachment of the temporary cladding structure. It was to use box-shaped cladding structures.

When the partial repair work is completed and the corresponding repair work is completed, the entire repair structure is lifted and mounted to a position for repairing other repair structures using a lifting device such as a small crane mounted on a barge. It can be said that the box structure, which is a steel structure with upper and lower sides, which is technically characterized by being able to complete a work such as a repair and efficiently performing work such as repair of the entire repair structure.

Specifically, in the case where the hydraulic pressure surface is vertically formed, such as the footnote 110, the door 120, the drainage lock 130, or the side retaining wall 140 of the drainage lock which is a repair structure as shown in FIG. When the vertical ends of the box structures 100a and 100b are brought into close contact with the hydraulic pressure surface, and the hydraulic pressure surface is formed horizontally, such as the bottom plate 150 of the drainage lock, the lower surface of the rectangular box structure 100c is horizontal. It can be divided into the case that the end is in close contact with the surface to be pressurized.

The temporary cladding structure uses a weight or a hydraulic pressure of the temporary cladding structure in order to closely contact the hydraulic structure portion in which the hydraulic surface exists. In the case of a drainage lock or a retaining wall in which the hydraulic surface is formed vertically The vertical end of the temporary cladding structure is brought into close contact with the vertical surface of the drainage barrier or the retaining wall by receiving hydraulic pressure (100a, 100b). It is technical feature that it is in close contact with).

At this time, in the temporary clasp structures (100a, 100b) that the vertical end is in close contact with the hydraulic structure by the applied hydraulic pressure, when the water depth is very large, the water pressure is forced to act on the temporary clam structure, the water pressure acting as a temporary clam As the structure is transmitted to the repair structure through the structure, excessive hydraulic pressure is transmitted to the repair structure (drainage lock, retaining wall), which may cause a problem of structural safety.

In the case of the temporary water barrier structure 100c in which the horizontal end is brought into close contact with the repair structure due to its own weight, if it is necessary to increase its own weight so as to counteract it in order to be less affected by the differences between tides and waves, it is necessary to temporarily increase the weight. Due to the large size of the watertight structure, the manufacturing cost is inevitably high, and in order to transport the temporary watertight structure with a large weight from the land to the sea, a tugboat is mounted on a barge using a large crane and tugs the barge to a predetermined position. The problem is that the installation and transportation work of the installation and transportation work, such as the capacity of the need to be increased, and the construction cost must be increased.

An object of the present invention is to provide a transport means that can cover the entire repair structure without installing a water block structure such as a conventional sheet pile, easy and fast temporary water block structure for only the repair structure portion to be transported after installation By providing a means to carry out the work on the entire repair structure by providing a temporary block structure that can improve the workability of the repair structure installation work and shorten the working air, but does not threaten the structural safety of the repair structure, It is to provide a temporary barrier structure using buoyancy and self-weight, which is easy to install and dismantle, and a new construction and repair method using the same.

Another object of the present invention is to provide a temporary block structure using buoyancy and self-weight, and a repair structure new construction and repair method using the same, which is easy to install at the end of the temporary block structure in contact with the repair structure and is provided with a recycling means.

 Another object of the present invention is reusable, temporary block structure using buoyancy and self-weight, including the internal reinforcement means for properly supporting the hydraulic pressure and the escape prevention means to ensure safety and the construction and repair of new structures using the same It is to provide a method.

The present invention, in order to solve the above technical problem, because it is in contact with the sea water or fresh water, so as to be able to be used in the operation, such as repair of the repair structure in which the water pressure surface exists, to minimize the portion of the repair structure to be established and repaired It is installed so that the end is in contact with the water pressure surface while wrapping in size, the water pressure acting on the repair structure is transmitted to resist the water pressure by its own weight so as not to threaten the structural safety of the repair structure, the size of the temporary clamshell structure The water can accommodate water in the temporary cladding structure to facilitate the dismantling and transport of the temporary cladding structure by allowing the self weight to be increased and controlling the size of the self weight arbitrarily small without increasing the weight. Temporary water barrier structure when forming a receiving space to fill water in the receiving space The self-weight of the water is increased, and when the water is discharged, the buoyancy is generated in the temporary water cladding structure to reduce the self-weight of the temporary water cladding structure, thereby making it easy to install and dismantle the temporary water cladding structure. do.

Hereinafter, with reference to the accompanying drawings the most preferred embodiment that can be easily carried out by those of ordinary skill in the art in detail with reference to the accompanying drawings, the construction and repair method of the temporary cladding structure and repair structure using the same Explain separately.

<Temporary Clapboard Structure>

In the temporary water cladding structure installed so that the end portion is in contact with the temporary water cladding structure in which the water pressure surface of the present invention is formed, the water receiving space is formed to receive buoyancy in a state in which the water is not filled. In the filled state, it is a structure assembly formed to resist water pressure acting by its own weight including the weight of water. A description with reference to FIG. 2 is as follows.

Repair structure 100 having a water pressure surface is usually installed at the point where fresh water and sea water meet, and installed between the door 120 is installed on the lower end 110 is the drainage lock 130 is moved up and down , And the retaining wall 140 constituting both sides of the repair structure in succession with the drainage lock and the bottom plate 150 continuously formed at the lower portion of the drainage lock, the door and the vowel, will be described in detail.

The drainage lock 130 is installed between the door 120 as shown in Figure 2 and moved up and down along the door by a separate lifting device having a function of opening and closing the structure of the repair structure, submerged in seawater The part is subjected to water pressure according to the depth, so that the blood pressure side always exists. The pressure-receiving surface corresponds to a portion where the ends of the temporary water barrier structure 200 to be described later are in close contact with each other.

The retaining wall 140 is constructed at a predetermined height on both sides of the repair structure in succession with the drainage lock 130 to support a ground such as soil on the rear surface of the retaining wall. There is always a water pressure surface under constant water pressure, and it is also a target structure that needs to be repaired if the concrete covering constituting the surface is damaged.

The door 120 has a function of supporting the drainage lock 130 as a concrete columnar structure. In particular, the area that is in contact with seawater is subjected to continuous loads (water pressure due to blue) due to waves, etc., so that there is a great possibility of damage in concrete coating, and the lower part submerged in seawater also has a lot of room to be scoured by blue, so it has an elliptical cross section. The column 110 is separately installed to distribute the load due to the wave, so that the door is not in direct contact with the sea water, and it is common to have a scour reinforcement means such as a separate support portion (a kind of haunting portion) at the lower end. Furthermore, since the nunju formed on the door is almost submerged in the seawater, the locked part is always subjected to water pressure, and thus the water pressure surface always exists, and in the case of a damaged nunju, repair work is required to belong to the object structure.

The column 110 is formed in an elliptical cross section at the bottom of the door 120 is installed with a predetermined height.

Since the bottom plate 150 is a concrete plate having a predetermined thickness in succession with the lower part of the door and the door, it is always submerged in seawater, so that the upper surface (surface) is always subjected to hydraulic pressure, so that the water pressure surface always exists. In the case of damaged floorboards, repair work is required and the water barrier belongs to the target structure.

In particular, in the case of the column 110, door 120, retaining wall 140 and the bottom plate 150 may be seen as a structure in which the hydraulic pressure surface is present, it can also be seen as a target structure to be repaired or newly established. have. This is because the column, door, retaining wall and bottom plate are always in contact with the seawater and damaged by the waves, etc., so they belong to the object to be repaired. In the case of the column 110, door 120, retaining wall 140 and the bottom plate 150, if the concrete coating is damaged by waves caused by sea water, repair it, or to form a new structure on the damaged site Since it is essential to the work process of pouring and curing, a dry work environment is needed. The means for enabling such dry work is a temporary water barrier structure 200 that functions as a degree means.

A schematic installation of the structure of the temporary barrier structure 200 is also shown in FIG. 2.

That is, the temporary clam structure 200 is installed so that the end is in contact with the drainage lock 130 in which the water pressure surface exists, as shown in Figure 2, the inside of the object structure of the clam, such as the column 110 installed on the door 120 It is installed while wrapping at a predetermined interval from the box-shaped temporary clasp structure having a c-shaped cross-section opening and closing the upper and lower (200a, specific example 1 below),

It is installed so that the end is in contact with the retaining wall 140, which is the target surface of the water blocking structure, as shown in Figure 2, wrapped at a predetermined interval, the box shape having a c-shaped cross-section, the upper and lower sides are opened and closed. Temporary cladding structure 200b (hereinafter, Example 2),

It is also immersed in sea water, the end surface is installed to contact the bottom plate 150, which has a water pressure surface and is also a target structure of the water barrier, is installed while wrapping at a predetermined interval, the top and bottom of the rectangular box tube shape The temporary clasp structure 200c, it may be divided into specific examples 3 below.

Since the temporary cladding structures of Embodiments 1 and 2 have a hydraulic pressure surface formed in a vertical plane, the box-shaped temporary cladding structure having a c-shaped cross section so that the end surface of the temporary cladding structure in contact therewith may also be formed in a vertical plane (200a). , 200b),

Since the temporary cladding structure of Embodiment 3 has a hydraulic pressure surface formed in a horizontal plane, there is a difference in that a rectangular box-shaped temporary cladding structure 200c is used so that the end face of the temporary water cladding structure which is in contact with it may also be formed in a horizontal plane. .

Hereinafter, specific examples 1, 2 and 3 of the temporary water barrier structures 200a, 200b, and 200c will be described in detail with reference to FIG. 3.

<Temporary Water Block Structure 200a: Specific Example 1>

The temporary water barrier structure 200a of the first embodiment is a box structure having an overall shape having a c-shaped cross-section and having an upper and lower portions as shown in FIGS. 2 and 3a and formed of a double wall and having a water receiving space 250a therein. A steel frame assembly having a basic skeleton of the outer wall body 210a formed of both side plates 211a and the front plate assembly 212a formed therein, and an indexing means 220a formed at an end of the outer wall body in contact with a drainage lock having a hydraulic pressure surface. Is formed to be in close contact with the drainage lock, reinforcing member (230a) for supporting the water pressure applied by the sea water inside the outer wall body; And a separation prevention means 240a which functions to prevent the box structure installed in close contact with the water pressure surface due to the change of the sea water level, and is described with reference to FIGS. 3A to 3F.

FIG. 3A illustrates a perspective view of a state excluding a plate member enclosing the inside and the outside of the assembly to clearly show the configuration of each assembly constituting the basic skeleton of the temporary clam structure 200a. The outer wall body 210a of the temporary clasp structure 200a may have a structure in which both side plate assemblies 211a and the front plate assembly 212a are coupled to each other by bolts in a state where the flange 213a is coupled to each other. This shows only a case consisting of three assemblies due to manufacturing convenience, ease of transportation and the need for recycling, etc., the assembly of various sizes and shapes may be coupled to each other by bolts or other connecting means, if necessary. If the size is small, the whole may be produced integrally.

Each assembly 211a, 212a has a double wall structure. As a result, a space is formed in the wall, which is referred to as a water receiving space 250a in the present invention. The water receiving space is filled with water, the filled water is accommodated by the plate member surrounding the water receiving space.

The water receiving space (250a) is when the temporary clam structure is installed in close contact with the index means 240a on the water pressure surface in the present invention, when the water is filled by the weight of the water and the weight of the temporary clam structure itself, etc. And it is a means to resist when the external force by the hydraulic pressure acts on the temporary cladding structure, it is possible to prevent the phenomenon that the external force is transmitted to the pressure-receiving surface through the temporary clasp structure. If the external force is transmitted to the water pressure surface to act as a temporary blocking object structure containing the water pressure surface, that is, serves to prevent structural destruction by impact, such as drainage barrier, retaining wall.

In addition, when the water filled in the water receiving space (250a) is discharged to the outside through an underwater pump, etc., the temporary water cladding structure receives buoyancy in the water by the water receiving space, the buoyancy is eventually in the water of the temporary water cladding structure Since it plays a role of reducing self-weight, it is possible to reduce the capacity or size of transport equipment such as barges, cranes and towboats when it is necessary to separate and transport them from the hydraulic pressure surface such as drainage locks, etc. do.

In order to secure more self-weight secured by the temporary cladding structure composed of each assembly, water is added to the water receiving space 250a and at the same time, a heavy material such as concrete blocks is added to the lower ends between the vertical support members forming the water receiving space. In addition, the self-weight of the temporary cladding structure can be more secured.

3B illustrates a state in which water is filled in the water receiving space 250a and a weight 251a by a concrete block may be formed in the water receiving space by the sectional view taken along the line D-D in FIG. 3A. The level of the filled water may be determined in consideration of the height, buoyancy, etc. of the temporary cladding structure, and as the plate member 204a is formed as shown in FIG. 3d, a hole having a predetermined size is formed in the plate member so that the water is filled from the bottom into the water receiving space. It is also possible to fill the water in the upper portion of the water receiving space with a pump without forming a separate hole.

FIG. 3C illustrates a plan view of the temporary clasp structure 200a in which the assemblies 211a and 212a are coupled, and the hydraulic structure 100 having the hydraulic pressure surface in the state where the water stop means 220a is formed at both ends thereof. It is installed in close contact with the drainage lock 130, and the water film is installed to wrap around it with a predetermined distance from the footnote 110 formed on the door 120, which is the target structure, and functions as a degree means.

3D illustrates a cross-sectional view of the plate member 204a, the vertical support member 205a, the horizontal support member 206a, and the inclined support member 207a, which commonly form the outer wall body 210a. The members constitute each of the side plate assembly 201a and the front plate assembly 202a of FIG. 3A.

A plurality of horizontal support members 206a are connected vertically between two vertical support members 205a, and the inclined support members 207a support both vertical support members diagonally. Both vertical support members have plate members 204a formed on the outer surface thereof, so that when water is filled in the water receiving space 250a formed between the two vertical support members, water flows out to the outside by the plate members. Is accepted.

The material of the plate member, the horizontal and vertical support member and the inclined support member, the installation interval, and whether or not the support member is installed may be determined by the size of the water pressure according to the level of water filled in the water receiving space, the level of seawater outside the outer wall, the size of the structure to be covered with water, It changes according to design criteria according to working environment (wave strength, tidal difference, etc.). At this time, the size of the water receiving space should be able to ensure at least the size of the temporary water barrier structure (200a) floating in the water by buoyancy.

The water discharge means 220a is seawater from the inside of the box structure when both ends of the side plate assembly 211a and the lower end portions of the front plate assembly 212a are in close contact with the drainage door or the bottom plate where the hydraulic surface is present as shown in FIG. 3C. It has a function to prevent the inflow, and as shown in Figs. 3c and 3d includes the water supply means 1 formed on the entire vertical end surface of both side plate assembly and the water supply means 2 formed on the entire horizontal end surface of the front plate assembly.

The index means 1 may be a bar-shaped index member 1 221a having elasticity and an air tube 222a installed between the index member 1 as a rubber material, as shown in FIG. 3C. When the surface is made of I-shaped steel, the bar-shaped index member 1 (221a) is inserted into the I-section steel, and the air tube 222a is inserted between both index members 1, and then the water is filled in the air tube so that the tube is the index member. Press to 1 In general, a sealing agent is applied to the interface between the end face of the side plate assembly and the pressure-receiving surface by using a wooden board as an index means 1, which is very poor in construction and difficult to secure quality. The workability is very good, and the water efficiency is very high because the water leak is required to be indexed as necessary. Furthermore, by using the elastic bar-shaped index member 1, there is also an advantage that the external force such as water pressure acting on the temporary water barrier structure can be buffered to some extent.

As shown in FIG. 3D, the water repellent material 2 (223a) is inserted into the I-beam beam forming the lower end portion of the front plate assembly, as shown in FIG. Will be.

The reinforcement member 230a is a reinforcement means for securing rigidity of the box structure which can be additionally installed to resist external force due to water pressure for the safety of the temporary cladding structure itself composed of the outer wall as shown in FIG. 3C. 3E to 3F illustrate specific examples.

FIG. 3E is an example of a reinforcing member installed on the portion 110 of the temporary clam structure (AA section of FIG. 3A), and is installed across the upper portion of the column between the vertical support members 205a constituting the outer wall 210a. The upper reinforcing member 231a, the lower reinforcing member 232a installed by the jack between the circumference 110 and the vertical support member 205a, and the inclined reinforcing member formed between both side plate members and the front plate member of FIG. 233a). Each reinforcing member may be installed in a plurality of up and down depending on the size, water pressure, etc. of the temporary cladding structure. Thus, in addition to the rigidity secured by the outer wall body by each reinforcing member, it is possible to additionally support the hydraulic pressure.

Each of the reinforcing members may use a-shaped or c-shaped steel, and the hydraulic jack 234a is installed at the end of the lower reinforcing member installed on the circumference 110 so as to be opposite to the load due to the hydraulic pressure transmitted by the lower reinforcing member. By applying a load, the hydraulic pressure acting on the plate member and the supporting member is composed of a simple complementary load action instead of a cantilever load action, so that it functions more effectively as a reinforcement member for hydraulic pressure support by seawater.

Since the installation of the upper reinforcing member does not interfere with the upper portion of the column, the upper reinforcing member 231a may be installed between the vertical support members 205a using I-shaped steel, etc. In FIG. 3E, two upper and lower sides are installed. However, the installation status and the number of installation can be changed.

Figure 3f is an example of the reinforcing member installed on the portion of the door 120 (temporal section BB of Figure 3c) of the temporary clasp structure, in particular, the reinforcing member 235a using the hydraulic jack 234a in the door 120, It shows the state positioned downward.

The escape preventing means 240a is a case in which the temporary cladding structure may be separated from the drainage lock due to a change in the magnitude of the water pressure acting on the temporary cladding structure when the temporary cladding structure changes in the seawater level according to the tidal water. By referring to the means for fixing the temporary cladding structure to the rim and door by using the chain block 241a and the wire 242a will be described with reference to Figures 4a to 4d.

Figure 4a is a schematic installation diagram of the separation preventing means including the chain block and the wire, the wire 241a and the chain block 242a (upper part) and the door (installed on the upper end of the door 120 and the temporary cladding structure ( 120, it can be seen that the wire 241a and the chain block 242a (lower) to be installed at the lower end and the temporary cladding structure may be installed, respectively.

In addition, as shown in FIG. 4B, a support plate 244a fixed by a chemical anchor 243a is installed at an upper portion of the drainage lock, and one end of the wire 241a having a chain block 242a formed therein is connected to the support plate. The ends may be connected to the lifting rings of the outer wall of the temporary cladding structure to prevent the temporary cladding structure from being separated. In addition, a support plate is installed on both sides of the lower end of the door by a chemical anchor, and one end of the wire is formed by connecting a chain block in the middle of the support plate, and the other end is temporarily connected to a horizontal support member or a vertical support member in a diagonal direction. It is possible to prevent the detachment of the structure.

In addition, a means for increasing the self-weight of the temporary cladding structure may be used as a release preventing means for preventing the positional deviation from the drainage lock of the temporary cladding structure. That is, as shown in FIG. By increasing the weight of the temporary cladding structure by increasing the weight of the temporary cladding structure by additional loading load, it is also possible to prevent the positional change of the temporary cladding structure due to the fluctuation of the seawater level, which is to be symmetrical with respect to the center of gravity of the box structure. It is desirable to install. The total weight of the heavy weight and the installation position may be changed depending on the size of the box structure and the water level of the seawater.

The upper part of the temporary clasp structure further includes a lifting means formed with a lifting ring or a lifting hole so that the temporary clasp structure can be easily moved and installed by a crane mounted on a barge when the temporary clasp structure is installed and dismantled, as shown in FIG. 4B. At least two or more units should be installed on top of the clapper structure.

The detachment preventing means is installed inside and outside the structure and has a function of supplementing the water pressure by seawater or fresh water. Therefore, the installation status, the number, the material and the shape thereof are structural members that support the load. It can be changed by the enemy.

<Temporary Water Block Structure 200b: Specific Example 2>

As the temporary clam structure of the present invention, the temporary clam structure of Embodiments 1 to 3 described above may be used. That is, in the case of the target structure of the water barrier such as the column 110, a temporary water barrier structure having a C-shaped cross section of the specific example 1 is produced in advance in a field or a yard near the field, and in the case of the target structure of the water barrier such as the retaining wall 140. Temporary cladding structure of 2 is prepared in advance, in the case of the bottom plate 150 to produce a temporary clasp structure of the specific example 3.

Since temporary lifting structures of the embodiments 1 to 3 are each formed with lifting means at the upper end, the crane mounted on the barge is first used to closely install the manufactured box structure to the hydraulic pressure surface of the drainage lock, the bottom plate or the retaining wall. Use it to move the temporary cladding structure onto the barge and tow the barge to the final installation position. At this time, it is preferable that the bottom plate, etc., of the position to be finally installed be selected from the bottom so that it does not tilt in either direction when installing the temporary clam structure by mobilizing the diver.

The temporary temporary cladding structure is installed in such a way as to be connected to the lifting means formed in the temporary cladding structure by using a lifting device such as a crane mounted on a barge to the drainage lock which is the final installation position. At this time, since the water receiving space of the temporary clam structure is not filled with water, it is possible to install easily by using buoyancy in a part of which is submerged in water.

Once the temporary cladding structure is installed, the internal seawater can be pumped out to form the interior of the box structure into a dry working environment. At this time, it is checked whether there is seawater penetrating into the temporary cladding structure by an index means installed at the end of the temporary cladding structure. In the present invention, since the index means 1 and the index means 2 are provided in duplicate, a perfect index is possible.

If the temporary cladding structures of Embodiments 1, 2 and 3 are in close contact with the drainage lock, the bottom plate or the retaining wall, reinforcing means and detachment preventing means may be additionally installed inside the temporary clasp structure. Furthermore, when the wave is heavy, it is possible to prevent the deviation of the position of the temporary cladding structure by installing a heavy load over the temporary cladding structure to increase the weight of the temporary cladding structure. Temporary cladding structures 200a, 200b, and 200c mounted at predetermined positions fill water (sea water) in the formed water receiving space. As a result, the self weight of the temporary clam structure becomes large, and waves and water pressure acting on the temporary clam structure are not transmitted to the temporary clam object structure, such as a drainage lock.

As a result, the worker can repair the damaged column and retaining wall by using work aids such as a circular ladder and a work plate separately installed on the temporary cladding structure, and install a new structure if necessary.

When the repair of the temporary cladding structure is completed, dismantle the necessary reinforcement means, additionally installed weights or escape prevention means, and discharge the water filled in the water receiving space to the outside to reduce the weight of the temporary cladding structure. do. In other words, the buckle buried in the water is buoyancy is generated as much as the weight of the water corresponding to the water receiving space, because the self-weight of the temporary clam structure is reduced by that much.

In order to move to another position, using barge's lifting device, it is connected to lifting means of temporary clam structure and lifted up, and then moved directly to another position or loaded on barge, and then moving barge to a predetermined position and then temporarily It is installed in such a way as to mount the water barrier structure, and the operation of refilling water in the water receiving space is repeated.

This makes it possible to continuously repair the entire object structure, such as scaffolds, bottom plates and retaining walls.

At this time, if you make the minimum temporary cladding structure to fit the working air and adjust the number of installations and the number of movements, you can install the temporary cladding structure with minimum production cost. The box structure can be reused, so it is very economical.

Installation and dismantling of the temporary clamshell structure of the present invention can be determined in consideration of various site conditions, such as a combination of tugboat, barge and the like.

Temporary cladding structure of the present invention is made to the minimum size possible to work while supporting the water pressure as much as possible without threatening structural safety to the object structure, and by the effective reinforcement means is installed by the additional reinforcement means and separation prevention means The worker can work safely in the area, and the buoyancy and self-weight are installed so as to partially wrap around the target structure, so that it is possible to produce an economical temporary clam structure, which can be transported from the field to the sea or at sea More economical means of transportation can be used, enabling economical water barrier work, allowing workers to repair or build repair structures quickly, and move them to the desired location when the work is completed, and recycle. To make temporary barriers faster I can finish it.
