As such, when the separator 120 is provided, dredged soil may be injected for each unit accommodating part 150 corresponding to one injection part 110.

And, the handle 170 is provided on the outer surface of the body portion 101.

The handle 170 is for moving the tube structure 100, it is configured in the form coupled to the body portion 101 along the longitudinal direction of the body portion 101.

The handle 170 may serve to be connected to a power unit such as another barge for movement.

Referring to the various forms of the method to proceed with the revetment and landfill construction that is constructed by using the temporary revetment tube structure configured as described above are as follows.

8 is a view showing a process for building a temporary draft by using the tube structure of the present invention.

As shown, the tube structure 100 is stored in a rolled form on the roller 220 of the barge 200 floating in the sea or lake to be buried, and the tube structure (where 100 may be installed in such a way that the roller 210 is released as much as the required length.

In addition, unlike the barge provided with the roller through the injection unit 110 of the installed tube structure 100, the dredged soil 10 at the bottom of the water is pumped using the barge 300 prepared separately from the pump 330 and the injection pipe. Injection into the inner receiving portion 150 of the tube structure 100 by using the (310).

At this time, the dredged soil 10 pumped by the pump 330 is used as the dredged soil under the water surface on the outside of the tube structure 100, that is, the opposite side of the coast.

In this case, the weight of the tube structure 100 is gradually increased, and when dredged soil is injected until the weight greater than buoyancy is applied, the tube structure 100 sinks to a bottom surface such as the sea and is fixed at a predetermined place. Will be able to maintain.

Meanwhile, in FIG. 8, the tube structure 100 is completely submerged under the surface of water, that is, a process of installing a tube structure forming a temporary relief in a deep sea.

Next, Figures 9 to 12 are attached to the sequence showing the process of constructing the relief using the tube structure.

First, FIG. 9 is a cross-sectional view showing three dredged soils 10, the tube structure 100 injected into the inner receiving portion 150 is installed on the floor under the water surface as shown in FIG.

At this time, the number of the tube structure 100 to be installed is not necessarily three, as shown, may be installed of the required number of course.

Next, as shown in FIGS. 10 and 11, the auxiliary fixture 180 is installed on the upper portion of the tube structure 100 installed as a temporary arc based on the bottom under the water surface.

Here, the auxiliary fixture 180 may be made of a tube structure of the same type as the tube structure 100 installed on the bottom.

In this case, as shown in FIGS. 10 and 11, the auxiliary fixture 180 may be installed to be in close contact between the tube structures 100 installed on the floor in a temporary arc. In other words, it will be possible to prevent dredged soil or water from flowing through both sides of the lake.

Then, after the geosynthetic sheet 220 to surround the tube structure 100 and the auxiliary fixture 180 at the same time, as shown in Figure 12, to the outside of the geosynthetic sheet 220 reinforcement structure ( 190 is installed.

Here, the reinforcing structure 190 may be selected soil, such as rock or gravel used when installing a conventional general revetment, it may be composed of two or more layers (191,192).

As described above, in the case of constructing the revetment using the temporary temporary relief tube structure 100 of the present invention, after installing the tube structure 100 at the place where the revetment is to be constructed during initial operation, the dredging soil 10 is injected into the surrounding area. Since the basic installation work is made, it is advantageous in terms of time and cost.

That is, when the foundation work for conventional reclamation, it is necessary to carry a separate member or foundation rock for the installation of the revetment in a separate place, and in the case of the sea, the foundation rock, etc. after installation by the algae was difficult to work, but the present invention In this case, the basic installation work is carried out in the city factory, and there is no problem of dredged soil, so the work efficiency becomes much more favorable.

In addition, since the auxiliary structure 180 or the reinforcement structure 190 is installed after installing the tube structure 100, which forms the basic installation member on the bottom, the construction work becomes easier in the overall revetment construction side.

Further, by using a tube-type auxiliary fixture 180 such as a tube structure to prevent dredged soil, algae, etc. to pass through both sides of the lake through the lake shore construction work becomes easier.

Next, with reference to the accompanying Figures 13 to 17 will be described another process of building a revetment using the tube structure of the present invention.

First, as shown in FIG. 13, a proper number of tube structures 100 are installed at an arbitrary distance away from the shoreline, and then, as shown in FIG. 14, dredged soils below the surface of the tube structures 100 forming a temporary revetment ( 10) is filled in the space to be buried between the tube structures 100 and the shoreline using a pump 330, barge 300 and the injection pipe 310.

FIG. 15 shows that the dredged soil is filled between the tube structures 100 and the coastline forming the temporary relief through the above process.

Then, as shown in Figures 16 and 17 attached, using the geosynthetic sheet 220 to cover the outside of the temporary relief consisting of the tube structure 100 after the reinforcing structure portion 190 to the outside of the required number of layers Install to achieve (191,192).

Here, the geosynthetic sheet 220, the dredged soil 10, etc. buried between the tube structure 100 forming a temporary relief to prevent the counting to the outside, the installation of the reinforcement structure 190 and the like installed on the top Serves to facilitate.

Next, FIGS. 18 to 20 are views for illustrating a method of refilling the tube structure while moving the temporary structure.

That is, the tube structure 100 is installed at a predetermined distance away from the shoreline (S10), and the dredged soil 10 is injected into the tube structure 100 (S20).

Then, after filling the dredged soil 10 through the pumping operation between the tube structure 100 and the shoreline (S30), the tube structure 100 is moved again to a predetermined position and the tube structure from the previous buried position The landfill construction is made in such a way as to fill in between (100) (S50).

In this case, when the tube structure 100 is moved to a place where the next temporary revetment is installed, the dredged soil 10 which has been injected into the inner receiving portion may be discharged to the outside (S40). Alternatively, other carriers may be used to move even when the dredged soil is filled.

This process is repeatedly performed until all of the predetermined landfill area is reclaimed (S60).

And, although not shown, in the case of the temporary shore is finally installed on the outermost from the shoreline, as shown in Figures 12 and 17 attached, geosynthetic sheet 220, auxiliary fixture 180 or reinforcement structure It may be desirable to use 190 to construct a finished reinforcement with enhanced durability.

21 to 24 are cross-sectional views sequentially illustrating a process of constructing a levee using a tube in the soft ground, and FIG. 25 is a flowchart illustrating a process of constructing a levee using a tube in the soft ground.

21 to 25, the soft ground displays the excavation position of the soft ground in advance (S100). That is, as shown in Figure 21, the position (a to h) and the like to be excavated for each predetermined section is displayed above the ground.

Then, as shown in Figure 22, after the step of excavating the displayed soft ground (S200), the tube 100 is laid on the excavated soft ground (S300).

At this time, it goes without saying that the step of injecting dredged soil into the laid tube (100) (S400).

In this case, as shown in FIG. 23, the ground remaining between the installed tubes may be excavated by a predetermined height (hereinafter, also referred to as "plan") (S500).

Next, a step (S600) of constructing a dike using the tube in which the dredged soil is injected is performed, which is the same as in the above-described embodiment, and thus a detailed description thereof will be omitted.

In this way, when the dike is constructed on the soft ground, the dike can be constructed while preventing the soil from collapsing along the incline that occurs during the excavation of the soft ground. This brings the advantage of not having to carry out the transfer operation.

As described above, the preferred embodiments of the present invention have been described, and the fact that the present invention can be embodied in other specific forms in addition to the above-described embodiments without departing from the spirit or scope thereof has ordinary skill in the art. It is obvious to them.

Therefore, the above-described embodiments should be regarded as illustrative rather than restrictive, and thus, the present invention is not limited to the above description and may be modified within the scope of the appended claims and their equivalents.

For example, in the city and description, but shown and described mainly in the process of reclamation work on the basis of the sea, that is, the seashore, of course, the application of the present invention can be applied to other rivers, lakes, or waterproofing.
