Definitions
- the present invention relates to a caisson structure and a construction method, and more specifically, by introducing a new concept of an open cell and an intercell to a caisson, as compared to the conventional individual caisson structure, while reducing the number of walls to reduce the manufacturing cost to the construction method There is almost no difference, and it relates to a flexible caisson structure and its construction method which can interlock neighboring caissons into flexible sandstones, and each caisson can respond individually to uneven settlement of the ground.
- caisson is a structure that is essential to the construction of the port. For example, it is applied to important facilities of ports such as gravity barriers and breakwaters.
- caissons In the case of breakwaters, caissons must withstand the horizontal forces of the waves at their own weight. By the way, blue is not always constant, and the horizontal force of blue is concentrated frequently in one caisson. However, assuming that the horizontal force is concentrated, the caisson is designed to increase the weight of caisson, which leads to an increase in cost and deterioration of constructability. For example, the greater the load on the caisson, the higher the manufacturing cost, and the greater the scale of heavy equipment, such as cranes that can handle it.
- an interlocking section in which reinforcing bars are interwoven between two neighboring caissons is made, and this space is isolated from seawater, and concrete is poured to construct a caisson construction method in which the two neighboring caissons are integrally joined at the point where they meet each other. There is a bar.
- this construction method is not only difficult to construct itself, but after construction, the caissons are completely integrated by the concrete placed in the space where the two caissons face, so that the caissons on the ground where the unequal sedimentation occurs when the ground unequal sediment occurs It is not possible to sink naturally, and there is a high possibility that the stress caused by the failure of the caisson of such a very high load is concentrated in a specific area and the caisson is destroyed.
- the external force due to the waves continues to work for more than 30 to 50 years after the caisson is constructed, and during this period, If the interlocking part between neighboring caissons is not flexible and the interlocking part is deformed like a rigid body after a while, one caisson with the concentrated horizontal force is pushed backwards to transfer the load to both interlocked caissons. As the load is concentrated at one point of the interlocking site acting as a rigid body, there is a high possibility that the caisson will be broken.
- the caisson is not susceptible to blue waves because the caisson does not exert its design load until the filling material is filled inside the caisson. If an unexpected wave occurs before the filling of the caisson is completed, the caisson will be pushed by the waves and fall. Therefore, a method of preventing caisson from being destroyed during construction is required.
- the mound installed in the lower part of the interlocking caisson structures disclosed in the prior art only functions to support the caisson structure from the bottom and provide friction resistance, but such mound can also be interlocked if it can continuously contribute to the caisson interlocking structure. The effect could be even greater.
- the present invention has been made to solve the problems described above, it is possible to omit the walls of both ends of the caisson to reduce the number of walls and to make the wall thinner to reduce the overall construction cost, while the construction is good, the two neighboring
- the interlocking of the neighboring caissons can be flexibly interlocked, effectively resisting the blue waves and preventing damage to the interlocking sites in spite of the ground unevenness.
- the interlocking area remains flexible during the decades after construction, and the interlocking of the neighboring caissons before completing the filling of the caissons not only after construction but also during the construction process allows the harbor structures to be used during construction. Open cell can ensure high stability It aims to provide a Basin structures and construction methods.

- the dead stone filled in the space of the intercell 22 may be a standard corresponding to the dead stone of the mound.
- the dead stone filled in the intercell 22 space may be connected to the mound through an open lower portion of the intercell 22.
- a method for constructing the caisson structure the step of laying a foundation stone on the upper surface of the seabed to form a mound; Leveling the mound top surface; Forming an intercell 22 by arranging a plurality of caissons 10 in a lateral direction so that the open cells 13 face each other; And filling the filling material in the cell 12 of the caisson 10 is placed, the intercell 22 is filled with a stone of the standard corresponding to the basic stone, the interior of the intercell 22 is a mound foundation stone It provides a caisson construction method comprising the step of: to be kept in a flexible state connected with.

- FIG. 2 is a perspective view of a caisson as an embodiment according to the present invention
- Figure 3 is a perspective view of the caisson of FIG.
- the conventional caisson 90 illustrated in FIG. 1 forms a cell 92 of 4 * 3 in width and length, and for this purpose, sidewalls extending in the left and right directions on the drawing are spaced apart from each other in front and back, and In the drawing, the sidewalls extending in the front-rear direction are arranged to be spaced apart from each other five side by side.
- These conventional caissons 90 are aligned to the left and right, and then placed, and then the filling block is installed in the cell 92, the upper block is installed.
- the caisson according to the present invention is provided with a cell 12 of the width * length 3 * 3, the width * length 1/2 * 3 Open cells 22 are provided at both ends thereof, and the same number and volume of cells as the conventional caisson 90 are provided, while the side walls extending in the left and right directions on the drawing are spaced apart from each other in front and rear four side by side. And, the side wall extending in the front-rear direction on the drawing is a form in which four side by side spaced apart. That is, the number of side walls is reduced by one compared with the conventional caisson.
- the length of the front and rear members when the length of the front and rear members is about 0.5 to 3 m, the length of the two front and rear members facing each other corresponds to twice the length of the front and rear members, so that one cell is completely covered by the two front and rear members. It is possible to form an intercell.
- the front and rear members when the front and rear members are configured in the form of a cell (see FIG. 13), the length of the cell corresponding to the front and rear members may be set to about 6 m or less corresponding to the length of the closed cell 12.
- the intercell has the meaning of one intact cell and functions as a cell. Therefore, the intercell forms a joint on the faces facing each other between caissons, and blocks this portion to prevent water from flowing through the caisson gaps. It is clearly distinguished from the structure.
- the intercell functions as a cell for preventing the weight of the caisson and the rolling, and does not function to suppress the rapid flow of water into the gap between the caissons. Rather, the intercell does not block the flow of water because the interior of the stone is filled as described later.
- the wall 11 at both ends of the conventional caisson 90 as shown in Figure 1 is formed relatively thicker than the wall formed in the middle. Because the wall formed in the middle is filled with both cells 92 based on the wall, the load applied to both sides of the wall is the same, but the walls at both ends of the caisson are filled with the filler material on one side and on the other side. Because is in contact with sea water, the load on both sides of the wall is different. Therefore, looking at the conventional caisson it can be seen that the wall 11 of both ends is formed relatively thicker than the wall formed in the middle.
- the walls 11 at both ends of the caisson 10 may not be thicker than the walls formed in the middle.
- the both end walls of the caisson are also filled with the filling material in the cell 12 on one side and the filling material in the intercell 22 on the other side, so that the load applied to both sides of the wall is substantially reduced. It is worth noting that they become the same. Therefore, according to the features of the present invention, not only the side wall is reduced by one more than the conventional technology, but also the thickness of the side walls formed on both sides can be made relatively thinner than the conventional, thereby saving material as a whole. The cost of making caissons can be significantly reduced.
- the unit structure caisson 10 is a form in which the cell 12 is formed in the hollow portion as shown. Each cell 12 is defined by its walls 11 in volume. The bottom of the caisson is blocked so that the filling material does not flow down when the filling material in the cell 12.
- Both front and rear ends of the caisson are formed with front and rear members 14 protruding in both directions.
- the front and rear member 14 is a form in which the walls 11 defining the front and rear of the caisson are further extended to both sides, respectively. In this way, the space between the front and rear members defined by the front and rear members 14 on both sides of the caisson are open to each other, i.e., open shape, and in the description of the present invention, the open cell 13 This is called.
- the open cell 13 of the caisson is open like the other cells 12 in the open form. This is a natural structure to fill the filling material in the form of a dead stone in the space of the inter-cell 22 to be described later generated by the open cell (13).
- the open cell 13 of the caisson of the present invention is also open bottom.
- the lower part of the open cell 13 is not only completely open, but also partially open depending on various factors such as securing the strength of the caisson.
- the closed cell 12 of the caisson 10 is filled with a filler, and the lower part of the closed cell 12 is blocked, so that the filler filled with the closed cell serves as the weight of the caisson.
- the open cell 13 of the present invention has an open bottom. According to the caisson structure, since the part of the intercell 22 formed by the open cell 13 is formed by removing the member part constituting the bottom surface of the caisson, the reinforcement and the concrete material can be saved as much as the corresponding part. .
- the caisson 10 is installed on the mound installed on the sea bottom, and as described above, when the lower part of the open cell 13 is opened, the inner space of the open cell 13 is in communication with the mound.
- a plurality of shear keys 18 protruding outwardly to the side of the caisson are further formed between the front and rear surface members 14 respectively formed at the front and rear ends of both sides of the caisson.
- the shear key 18 may protrude outward by the same length as the front and rear member 14, or may protrude from the wall at a rate smaller than the protruding length of the front and rear member 14 as shown.
- the shear key 18 may have a shape protruding from the wall 11 in a trapezoidal shape as shown.
- the filling material in the shape of a sandstone is the front-rear member 14. Since all of the load is completely transmitted to the front and rear members 14, there is a risk of high load.
- the shear key 18 may have a frictional force with respect to the side surface of the wall due to the serpentine-shaped filler, so that the load is applied to the side and the shear key of the wall 11.
- the shear key 18 distributes and supports the load when the sandstone filled in the intercell 22 part by the external force is intensively applied to any one of the caissons.
- the shear key 18 is a configuration having no meaning in the case of a rigid body, rather than a flexible dead stone, which is filled in the intercell 22. Because, as described above, since the rigid body concentrates the load at one point of the wall of the caisson during the interlocking process, even if the shear key 18 is formed, the phenomenon that the load is concentrated at any one point is changed. Because there is no.
- the front and rear members 14 described above can be seen in a form in which the front and rear walls of the caisson 10 further extended to both sides, the shear key 18 described above is the caisson
- the wall 11 extending in the lateral direction to form the cell 12 of 10 can be seen to extend further to both sides.
- the caisson manufacturing method of the present invention is not so different from the conventional caisson manufacturing method. That is, the caisson of the present invention is not different from the conventional caisson in the manufacturing process as well as the construction method to be described later. Rather, it can be said that the cost of materials is less as compared to the conventional caisson in that one side wall formed in the front and rear directions and the bottom portion of the open cell are reduced.
- the haunch 15 is formed to reinforce the front and rear members. Since the front and rear members 14 are similar to the cantilever mechanically, the haunches 15 are formed at the inner edges of the wall 11 and the front and rear members 14 where stress is expected to concentrate. Forming the haunch 15 here has a special meaning when compared to the prior art. For example, when two caisson sections facing each other are integrally formed into a concrete block as in the prior art (Japanese Patent Laid-Open Publication No.
- the interlocking portion is integrally formed with the caisson. Therefore, there is no reason to use the haunch (15) as the present invention, but when the filling material in the form of a flexible sandstone form as in the present invention in the open cell (strictly inter-cell to be described later) portion to keep the filler in a flexible state, When two neighboring caissons receive different magnitudes of force in the front and rear directions, and the two caissons try to move relative to each other in the front and rear directions, the filling material in the shape of the sandstone distributes the load on the inner surface of the front and rear members 14, In order to prevent breakage of the front and rear member 14 having the cantilever shape, the haunch 15 has a great meaning in engineering.
- the front and rear members 14 and the shear keys 18 described above share the reinforcing bar arranged in the horizontally extending form with the caisson wall 11 or in the vertical direction in that the caisson wall is extended. Reinforcing bar reinforcement disposed in an extended form can be shared with the upper block 40 to be described later. Therefore, the front and rear face member 14 and the shear key 18 are integrally formed with the caisson wall in the horizontal direction, and integrally formed with the upper block 40 in the vertical direction, so that the strength thereof can be sufficiently ensured.
- reinforcing portions 19 may be formed at lower ends of the front and rear sides of the caisson.
- the reinforcement may be formed to protrude transversely to the lower end of the front wall and the rear wall, such as ribs.
- FIGS. 4 to 8 are views showing a method for constructing a harbor structure using a caisson according to the present invention in order
- Figure 9 is a view showing the form of the configuration for interlocking the caisson structure according to the present invention.
- the caisson yard will be selected to the nearest land that can be accessed by the caisson mounting work, and the land work will be carried out.
- the land works consist of floor stop work, rebar assembly, formwork assembly, and concrete placement, followed by caisson production on the yard.
- the movement of the caisson may be applied to the method of forming a claw in the caisson and fastening it to the hook of the marine crane, and the like, in addition to the various known methods can be applied.
- the specification of the foundation stone laid to install the mound can be based on the standard specification, which is currently 0.015 ⁇ 0.03 m 3 / EA in the domestic standard.
- the caisson is supported and towed to the sea site.
- the neighboring caisson is neighbored to mount the caisson again on its side, and at this time, the caisson and the caisson are attached to the caisson to prevent damage from contact with each other, so that the neighboring caisson 1 It prevents damage when the car is in contact and removes tires when precision is mounted.
- the intercells 22 are formed by two open cells 13 facing each other of two neighboring caissons. That is, the space partitioned by the front and rear members 14 of the two neighboring caissons and the sides of the caissons functions as a 'cell'. Intercell 22 means that two neighboring caissons must function to function as a cell. Since the intercell 22 is also defined by its front and rear members, its volume can be filled therein. Considering that the gap error between two caissons is 10 cm to 20 cm according to the current standard specification, the gap between front and rear members of two neighboring caissons may also have a gap error of 10 cm to 20 cm.
- the filling material 30 is filled in the closed cell 12 inside the caisson, and the filling material is also filled in the intercell 22 as well.
- the filling material 30 to be filled in the closed cell 12 may use natural sand or slag generated from steel smelting, etc., and a sand stone including bottom ash generated from a thermal power plant.
- the slag generated in steel smelting or the like is not preferable as a filling material to be filled in the intercell 22. Because slag reacts with water and expands, neighboring slags harden and solidify together, eventually deforming as a rigid body.
- the filling material to be filled in the intercell 22 it is preferable to use a filling material that maintains a permanently flexible state, such as natural sandstone.
- the filling material to be filled in the intercell 22 is sufficient to be a filling material in the form of a stone that can maintain a flexible state continuously over time without breaking well.
- the filling material filling the intercell 22 portion may be an interlocking sandstone 32 that maintains a permanently flexible state.
- the interlocking seat is larger than 10 cm ⁇ 20 cm, which is the distance between the front and rear members of the two caissons, and is prevented from leaking out through the gap in the intercell 22, but when the interlocking action occurs because it is not too large.
- the load is sufficiently distributed.
- the filling material (30) in the shape of the sandstone to be filled in the intercell 22 does not have a diameter larger than the gap between the two front and rear members 14, if the tighter interference between the filled seats are made It is also worth noting that much of the spill can be prevented.
- the dead stones filled in the intercell 22 must resist the displacement of two neighboring caissons in different directions in the front and rear directions, it is preferable that the dead stones interfering closely with each other unlike the dead stones filled in the normal cell 12.
- a compaction process may be performed on the filling material 30 in the form of a serpentine filled in the intercell 22.
- the diameters of all the sandstones filled in the intercell 22 are larger than the gap between two neighboring front and rear members 14. It would be desirable to construct.
- This interlocking structure when a large external force is applied to a particular caisson, and the load is applied to the interlocking site, the load is not concentrated by the sandstones and acts as a definite distribution load. The possibility of breakage can be greatly reduced.
- the interlocking seat 32 filled in the intercell 22 is in direct contact with the mound.
- the size of the sandstone laid in the mound is larger than the gap between the front and rear members of the intercell 22, and as will be described later, the load may be sufficiently distributed when the interlocking action occurs.
- the size of the interlocking sandstone filled in the intercell 22 is 0.015 ⁇ 0.03 m 3 / EA, it can be confirmed that the standard stones act as an apparent distribution load while being intertwined well without being damaged.
- the specification over 0.03 m 3 / EA is not larger than 10 cm to 20 cm, which is the tolerance for the gap between caissons.
- the filling material has a specification of 0.05 m 3 / EA or more, the interlocking stone breakage starts to occur due to the concentrated load between the stones, which may cause the outflow of the filling material.
- the interlocking sandstone is less than 0.001 m 3 / EA, the outflow is caused when the load is given rather than intertwined with each other.
- the specifications of the mound and the interlocking stone correspond to each other (for example, the specification of the interlocking stone to ensure that the interlocking action is properly performed with 0.015 to 0.03 m 3 / EA, which is the standard for the basic stone described above) 0.01 to 0.05 m 3 / EA correspond to each other), as shown in FIG.
- the back filling material 50 is installed on the rear of the caisson, and the upper block 40 is installed as shown in FIG. 8 to complete the construction of the port structure. That is, after filling the filling material 30 in the stationary caisson 10 can be installed on the upper end of the caisson, it can be filled with the back filling material 50 in the sand according to the construction purpose of the caisson.
- FIGS. 10 to 12 are views showing in sequence another method for constructing a port structure using a caisson according to the present invention. It takes considerable time to arrange a plurality of caissons side by side with offshore structures and to fill all of the filler material therein. Since the caisson weight is not as large as originally designed before the stuffing material is filled in the inside of the caisson, if the unexpected blue intensively acts on any one caisson, the caisson will be pushed over.
- the interlocking may be performed between neighboring caissons immediately by filling 25 to 50% of the cell 12, which is the caisson internal space, with a certain amount of self-weight.
- the cell 12 which is the caisson internal space
- the interlocking may be performed between neighboring caissons immediately by filling 25 to 50% of the cell 12, which is the caisson internal space, with a certain amount of self-weight.
- about 30% of the interior space of the caisson is filled with a filling material, and then interlocking work between neighboring caissons is performed.
- this interlocking operation is not special, and is completed by filling the filling material in the form of a sandstone as shown in FIG. 11 in the intercell 22 formed by two neighboring caissons.
- Conventional interlocking work is difficult or time-consuming, such as performing underwater or moving large interlocking members to the offshore site, or sealing the pouring space and pouring concrete after draining the seawater. This caused the increase of the cost.
- the interlocking method of the present invention can be executed immediately with the same operation as filling the filling material in the cell 12 without carrying heavy loads or submerging in water, thereby saving both cost and time.
- the present invention has the advantage that the time of construction can be selected regardless of the weather conditions.
- a work of filling the filling material in the individual caisson 12 may be performed as shown in FIG. 12.
- the caisson of the present invention is not necessarily to be constructed in this order.
- the filling material 30 in the form of a serpentine may be filled in the intercell 22.
- FIG. 13 is a view showing another embodiment of a caisson according to the present invention.
- the caisson shown in FIG. 13 and the caisson of FIG. 2 in addition to installing a simple front and rear member in front and rear of a position where the open cell is disposed to define the open cell 13 (see FIG. 2), it can be seen that the cell 12 can be further formed at the position. This not only increases the weight of the caisson itself, but also defines the front and rear of the open cell as well as forming one or more cells, without the need for special thickening of the front and rear members or forming the haunch 15.
- Figure 14 is a perspective view showing a process of installing a sand stone leak prevention cap in the caisson according to the present invention
- Figure 15 is a plan view of the caisson installed a seat stone leak prevention cap of FIG.
- the interlocking sandstone 32 is positioned so that the front and rear members 14 of two adjacent caissons 10 are adjacent to each other. Is unlikely to leak between Therefore, the separate configuration for preventing the outflow of the interlocking dead stone 32 is not required as described above.
