Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a hoisting structure using a frame and geosynthetics,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a revetment structure, and more particularly, to a revetment structure for constructing a billet by filling soil, sand, or dredged soil with a frame and a geotextile in a marine site, and a construction method thereof.

Conventionally, in order to install a harbor and a seawall for a harbor, for example, after a basic levee is formed by dropping stones, a rock stone of the size of a rock stone is formed on the sea side surface, And built a seawall.

As described above, since the stones located at the center of the embankment are used as stones having a large diameter, large water holes are formed between the stones and the stones due to the movement of water in the outer and lower water sides, There is a problem going on. In this case, if the flow velocity is not cut off, the dredged soil to be dumped at the inside of the reef is lost. In order to prevent the dredging, the filter seats and the filter mat with a small diameter are installed in order to install the filter seals. There is a problem that the waste of the material is large and the construction period is lengthened, the construction cost is increased, and the constructed product is scraped and the revetment is lost.

In other words, conventionally, in order to form a revetment bank, stones are loaded on a barge or by a dump truck, and then moved to a sea position and then applied to a predetermined position by an excavator or the like in a design standard or a gradient , There is a problem that the stones are not only dropped to the correct position due to the flow rate during the discharge but are also lost.

In addition, the cost of purchasing stones is high, and a large amount of stones are used, which increases the construction cost. Also, there is a problem that the environment is destroyed by supplying stones through the quarrying of the stones.

In addition, there is a problem that the workability is lowered because complicated operations such as dropping of stones, dropping of the clay on the sea side, gravel on the side of the landfill, mats and soil construction are required.

Also, as the soil and the like on the landfill are lost, the stability of the site is weak, the settlement of the site is also induced, and the marine is polluted.

In order to solve such a problem, Patent Document 1 (Registered Patent No. 10-1084674) is known.

Patent Document 1 discloses a method of constructing a breakwater by stacking a tube structure, a subsidiary structure, and a reinforcing structure to solve the problems caused by specular lamination such as stones, but the dredged soil is injected into the tube structure in the construction site, Since the tubular structure is a single space, the injection of the dredged soil takes a long time and the dredged soil can not be injected far from the injection site. In addition, since the tube structure and other auxiliary structures are used, the operation is troublesome and the coupling force between the tube structure and the auxiliary structure is weak, so that there is a problem in that a reliable revetment structure can not be constructed.

Patent Document 2 (Patent Registration No. 10-1268235) is an improvement of the problem of Patent Document 1, and it is an object of the present invention to solve the problems described in Patent Document 1, in which the central portion of a rectangular parallelepiped having a flat top surface, A shore pocket of a geosynthetic fiber material made of a trapezoid by two inclined portions; Wherein the central portion of the revetment pocket is formed of at least one of a longitudinal body and a transverse body inside the central body, the body being open at the top of the revetment pocket, and a clay bag made of a filler material filled in the inside of the revetment pocket, A partition wall for partitioning the inside of the central body into a plurality of fill portions, and a roof which is sealed after the filler is filled in the center body, the first and second inclined portions of the waterproof pocket include a triangular- And at least one injection head for injecting the filling material into the sloped portion body, wherein the sloped portion body is partitioned into a plurality of filling portions by being spaced apart from each other at regular intervals, , And a filler material (for example, , Sand, dredged soil, etc.), and then the soil pouch is manufactured to construct the revetment facilities. Thus, the filling material can be quickly filled and all the spaces can be uniformly filled. Therefore, it is possible to construct a solid revetment facility, It is possible to shorten the air and reduce the construction cost by constructing the trapezoidal revetment facilities by simultaneously injecting the filler material into the space, but since the pockets are made of geotextile, the self-supporting property is weak, It is difficult to manufacture a structure of the above-mentioned structure, and the manufacturing and construction workability is poor due to these reasons.

As shown in FIG. 1, the frame structure according to the present invention and the revetment structure using geosynthetic fibers have a three-dimensional frame 100; A mat (200) installed in the frame (100) to form a space for filling the filler; And a filling material 300 filled in a space formed to be shielded from the outside by the frame 100 and the mat 200.

As shown in FIGS. 1 and 2, the frame 100 is required to maintain its shape without being deformed when the filler 300 is filled as a skeleton of the revetment structure, and the use of various materials such as reinforcing bars, bamboo, steel bars, This is possible.

The frame 100 is composed of a bottom 110 and first and second wall parts 120 and 130 and the first and second wall parts 120 and 130 are inclined to be gathered with respect to the bottom part 110, It is formed in the form of a trapezoid, which is to show the same structure as the existing hull structure (levee). On the other hand, although the frame 100 may be made of a plate material without holes and used without the mat 200, it is preferable that the frame 100 is of a lattice type in which the longitudinal member and the transverse member cross each other in consideration of transportation and manufacturing.

The bottom portion of the frame 100 does not sink at the edge portion and the support portion 111 is formed to maintain a stable installation state even if the bottom surface is submerged.

The support part 111 protrudes from the edge of the bottom part 110 more than the first and second wall parts 120 and 130. That is, the first and second wall parts 120 and 130 extend from the edge of the bottom part 110 inward And connecting them to the spacing.

The support portion 111 may have various configurations such as a lattice type (mesa).

The support portion 111 provides a space for stably stacking the clay stone 1 and the clay stone 1 is supported on one or more sides of the first and second wall portions 120 and 130 And are piled on the slope.

The bottom part 110 is in the form of a rectangular frame as viewed in plan and the first and second wall parts 120 and 130 are installed on the bottom part 110 in mutually opposed directions (two long sides) And the remaining two portions of the bottom portion 110 without the two wall portions 120 and 130 are connected to a flexible wire (wire rope, chain, etc.) 140.

The bottom portion 110 and the first and second bottom portions 120 and 130 are not flexible due to the characteristics of the material and can support the reef structure in which the filler material 300 is filled. Nevertheless, It is possible to minimize the volume and to be installed at a height suitable for the site conditions.

The wire 140 is wired in the lateral direction to connect the first and second wall portions 120 and 130 and to be connected to the bottom portion 110 and the first and second wall portions 120 and 130 It is possible to do. The wire 140 is wired in various directions such as an oblique direction as well as a longitudinal direction and a transverse direction.

The first and second wall portions 120 and 130 are connected to the bottom portion 110 so that the bottom portion 110 can be folded (angle adjustable). For example, the bottom portion 110 and the first and second wall portions 120 and 130 are connected by wires A method of connecting with a knot, and a method of connecting with a hinge.

The wire 140 is preferably a flexible but non-stretchable material so that the first and second wall portions 120 and 130 can be unfolded only within the length of the wire 140.

The frame 100 having such a structure can be filled with the filler material 300 through the upper opening of the frame.

The upper cover 150 may be assembled to the upper opening of the frame 100. The top plate cover 150 is preferably of a lattice type and includes other materials that are equivalent in function to prevent the filling material 300 from being released to the outside, and the periphery of the top and second covers 120, .

The revetment structure can be provided with a walkway when the revetment structure is connected to the land by forming a packing layer on the top plate lid 150 with the upper part flat by the top plate lid 150. At this time, .

4 shows another example of the frame 100. The frame 100 includes first and second corner portions 100-1 and 100-2 which are respectively assembled on both sides of the bottom plate portion 100-1 and the bottom plate portion 100-1. 2, 100-3).

The first and second corner portions 100-2 and 100-3 are formed by a bottom connected to both sides of the bottom plate 110-1 and an inclined portion connected to a bottom end of the bottom of the bottom.

It is preferable that the bottoms of the bottom plate portion 110-1 and the first and second corner portions 100-2 and 100-3 are connected to each other via wires or clamps. And connects the first and second corner portions 100-2 and 100-3.

The mat 200 is used as a geosynthetic fiber in a prefabricated product in which the filler 300 is not released to the outside, and is fixed while being fixed to the inside of the frame 100 while enclosing the outside of the frame 100.

The filler material 300 may be earth, sand, dredged sand, sandstone, or the like.

Although the mat 200 can provide one space, there is a risk of leakage of all the fillers 300 when a local tear or the like occurs. In order to solve this, there are two pieces of the mat 200 as shown in FIGS. 5A and 5B The above space can be partitioned.

The method of forming two or more spaces may include forming at least one partition 210 in the mat 200. The barrier ribs 210 are both vertically and horizontally movable and may be of a lattice type, although not shown in the drawings.

When the mat 200 is installed inside the frame 100, the partition wall 210 can be formed in advance on the mat 200. When the mat 200 is installed outside the frame 100, Can be installed on the frame 100 and then the barrier ribs 210 can be installed later, and other barrier ribs are formed on the frame 100 by other methods.

The construction method of the revetment structure using frame and geosynthetic fiber is as follows.

1. Assembly of frame and mat.

The frame 100, the mat 200, and the filler 300 are loaded on a ship and conveyed to the construction site of the revetment structure.

Since the first and second wall portions 120 and 130 are folded in a folded state, that is, the first and second wall portions 120 and 130 are small in volume, the frame 100 is easily transported without causing interference with surrounding obstacles. The filler material 300 can only be used to dump a small amount of material (such as an amount of the assembly of the frame 100 and the mat 200 to be submerged in the water) since the site material 300 can be dredged.

After reaching the construction site, a mat (200) is installed on the frame (100) to produce an assembly of a frame and a mat.

Of course, it is also possible to assemble the frame 100 and the mat 200 and then transport them to the construction site.

2. Assembly of frame and mat assembly underwater.

After arriving at the construction site, the assembly of the frame and the mat is launched into the sea, and in this state, the filler material 300 is filled into the space of the frame and the assembly of the mat.

When the filling material 300 is filled, the assembly of the frame and the mat slowly sinks into the water while the load increases, and when the assembly of the frame and the mat sinks on the sea floor, the filling of the filling material 300 is stopped.

3. Filling.

Filler 300 is filled into the remaining space of the frame and mat assembly.

Filling of the filler material 300 can be performed by pumping the material up to a predetermined height, and then filling the filler material 300 by using the equipment of the loader.

When the first and second wall portions 120 and 130 are folded, the first and second wall portions 120 and 130 are naturally raised when the filler 300 is filled.

After completion of filling, the construction of the hull structure is completed, and the clay stone (1) is additionally installed to construct the covering layer.
