Description

Corrugated steel plate wall {CORRUGATED STEEL WALL}

The present invention relates to a wall, and more particularly, to a corrugated steel plate wall constructed as a retaining wall using a corrugated steel plate.

When extending a road adjacent to a mountainous area or constructing a tunnel crossing a mountainous area, a cut surface is formed on the side of the expanded road or the crossed tunnel. In the cut surface, also called road cut-off site, a rock fall prevention fence or concrete retaining wall is installed at the inclined lower part.

As such retaining walls, reinforced concrete retaining walls or block-type reinforced earth retaining walls are mainly used.

The reinforced concrete retaining wall is a rigid structure in which the retaining wall sphere is integrated, and directly resists the earth pressure with the structure's own weight and the weight of the soil on the upper part of the foundation.

These reinforced concrete retaining walls have disadvantages in that the installation and dismantling of the formwork and the rebar assembly process are essential, so the construction cost is high and it takes a lot of time. In addition, as the height of the retaining wall increases, the width of the foundation increases, the burden of construction cost increases, and the appearance of the retaining wall is determined by the formwork, so there is a limit in realizing various appearances.

On the other hand, the block-type reinforced soil retaining wall is a type that withstands earth pressure by its own weight by reinforcing the backing soil to be filled.

The block-type reinforcing earth retaining wall is a type of gravity-type retaining wall that resists the earth pressure of the rear surface by its own weight by arranging reinforcing materials such as the geogrid 20 at appropriate intervals and filling the soil to form reinforcing soil.

Since the block-type reinforcing earth retaining wall has a structure that resists the back earth pressure by the self-weight of the reinforcing soil, the higher the height of the retaining wall, the greater the self-weight, thereby increasing stability. On the other hand, the front block 10 may use a product of the same standard regardless of the height. Therefore, the higher the height of the retaining wall, the more economical it is compared to the reinforced concrete retaining wall, and the more excellent the appearance after construction is completed, the higher the proportion of use in recent years.

However, since this conventional block-type reinforced earth retaining wall has a structure in which the front block 10 is laminated to form the retaining wall, partial deformation of the retaining wall is easy to occur, and when the front block 10 is laminated, the retaining wall is formed in a curved shape. It is difficult to form, and since the front block 10 is made of a concrete material, there is a problem that the surface of the wall can be easily damaged by an external force.

The present invention was derived to solve the above problems, and allows the wall to be deformed into various shapes including curves according to the user's request, and allows the worker to quickly and easily construct it, while minimizing the width of the digging. The purpose is not only to reduce the construction cost by doing this, but also to present a corrugated steel plate wall that can actively replace the microscopic and unpredictable ground fluctuations that can damage or destroy the concrete wall.

In order to solve the above problems, the present invention is a corrugated steel plate wall that serves as a retaining wall by being constructed along the edge of a slope or slope on which soil is laminated to resist earth pressure and prevent soil collapse, and to have an internal space. an outer wall comprising a plurality of corrugated steel plates spaced apart from each other and arranged to face each other, one side of which is in contact with earth and sand to support the slope or slope, and the plate surface is repeatedly curved; a filler filling the inner space and reinforcing the rigidity of the outer wall; a support part having one end fixed to one side of the outer wall in contact with the earth and sand to support the outer wall against the earth pressure formed due to the earth and sand; It presents a corrugated steel plate wall, characterized in that it includes.

Here, the filling material performs the layer compaction operation after filling the inner space with a certain amount of embankment, and repeats the process of performing the floor compaction operation after refilling the predetermined amount of embankment to complete the filling of the inner space. can make it happen

In addition, when the slope or the slope is formed by embankment filling the soil, the support portion may be composed of a plurality of grids having one end fixed to the outer wall and the other end arranged to extend inside the soil.

In addition, when the slope or slope is formed by cutting the soil, the support portion includes a plurality of grids having one end fixed to the outer wall and the other end fixed to the rock wall existing inside the soil through the interior of the soil; It may consist of a fixing member fixed to the other end of the grid and inserted into the rock wall.

In addition, the fixing member may be composed of any one of anchoring, nail nail, earth anchor.

In addition, a plurality of grids may be installed to be spaced apart from each other by a predetermined interval along the height direction of the outer wall, and the distance between the grids may be gradually shortened toward the lower side in the height direction of the outer wall.

In order to solve the above problems, the present invention provides a first step of forming an internal space between the corrugated steel sheet and the corrugated steel sheet by installing two rows of corrugated steel sheets along the edge of a slope or slope on which soil is stacked; a second step of performing compaction work after filling into the inner space; a third step of repeating the filling and compacting operations until the inner space is filled with more than a certain amount of soil; a fourth step of connecting a grid to one side of the corrugated steel sheet when the internal space is filled with more than a certain amount of soil during the third step process so that the grid is extended and arranged into the stacked soil; We present a corrugated steel plate wall construction method, characterized in that it includes.

Here, when a rock wall exists inside the slope or slope, the fixing member may penetrate the inside of the rock wall, and the end of the grid may be fixed to the end of the fixing member.

The present invention has the effect of enabling the wall to be deformed into various shapes including curves according to the user's request, enabling the worker to construct it quickly and easily, and reducing the construction cost by minimizing the excavation width. .

And, there is an effect that can actively replace the microscopic and unpredictable ground fluctuations that can damage or destroy the concrete wall.

As shown in these drawings, the corrugated steel plate wall according to the present invention is a corrugated steel plate wall that serves as a retaining wall by being constructed along the edge of a slope or slope where soil is laminated to resist earth pressure and prevent soil collapse. As an outer wall made of a plurality of corrugated steel plates 101 spaced apart from each other and disposed to face each other at a predetermined distance to have an inner space 110, one side is in contact with soil to support the slope or slope, and the plate surface is repeatedly curved. (100) and; a filler 200 filled in the inner space 110 and reinforcing the rigidity of the outer wall 100; a support part 300 having one end fixed to one side of the outer wall in contact with the soil and sand to support the outer wall 100 against the earth pressure formed due to the soil; consists of including.

The outer wall 100 is composed of a plurality of corrugated steel plates 101, and the corrugated steel plate 101 has a large load-bearing capacity because the load and reaction force are uniformly distributed over the entire plate surface of the corrugated steel plate 101 due to the corrugation.

There is an advantage that these corrugated steel plates 101 are overlapped in multiple layers or used as a plate by connecting them to each other by a method such as bolting, or can be used as a pipe by giving a curvature to the corrugated steel plates and connecting them to each other.

In addition, the structure made of the corrugated steel sheet 101 has the advantage of being economical and easier to transport and assemble than other rigid structures.

The inner space 110 between the corrugated steel sheet 101 and the corrugated steel sheet 101 disposed to face each other is filled with a filler 200 such as sand, soil, or gravel, so that the outer wall 100 is composed of the corrugated steel sheet 101 It is desirable to increase the rigidity and bearing capacity of the

Since the corrugated steel plate wall according to the present invention forms the wall itself with the corrugated steel plate 101 as described above, the wall can be deformed into various shapes including curves according to the user's request, and the operator can construct it quickly and easily. It also has the effect of reducing the construction cost by minimizing the width of the excavation.

The filler 200 is filled in the inner space 110 between the corrugated steel plate 101 and the corrugated steel plate 101 and serves to reinforce the rigidity of the outer wall 100, and the filler 200 is sand, soil or It is preferable to be formed of a material having various diameters, such as gravel, to minimize voids when filling the inner space 110 .

And, in order to effectively minimize the voids between materials such as sand, soil, or gravel constituting the filler 200, the filler 200 is partially filled in the inner space 110, and then the compaction operation is performed and a certain amount is filled again. It is more effective to repeatedly perform the process of compacting after doing so to fill the internal space 110 .

By providing a rainwater flow path 210 by forming a groove of a certain depth on the upper surface of the outer wall 100 filled with the filler 200 completely, rainwater can be collected in the rainwater flow path 210 side to effectively drain the rainwater. It is preferable to prevent the corrugated steel sheet 101 from being spread outward by the filler 200 filled in the inner space 110 by flowing into the inside of the filler 200 filled in the outer wall 100 . do.

The support part 300 has one end fixed to one side of the outer wall in contact with the soil and sand, and serves to support the outer wall 100 against the earth pressure formed due to the soil and soil.

As shown in FIG. 2, when the slope or sloped area is formed by filling with soil, one end is fixed to the outer wall 100 and the other end is arranged to extend inside the soil. It may be composed of a plurality of grids 310 .

As shown in FIG. 3, when the slope or slope is formed by cutting of soil, one end of the support part 300 is fixed to the outer wall 100 and the other end passes through the interior of the soil and is present inside the soil. It may be composed of a plurality of grids 310 fixed to the rock wall 1 and a fixing member 320 fixed to the other end of the grid 310 and inserted into the rock wall 1 .

As described above, in the case of the support part 300 shown in FIG. 2, since there is no rock wall because it is simply a retaining wall in which soil is stacked, the support part 300 shown in FIG. 3 in order to improve the bearing capacity of the grid 310. The length of the grid 310 should be formed to be relatively longer than in the case of , and there is an advantage in that there is no need to penetrate the rock wall 1 with a separate fixing member 320 instead.

And, in the case of the support part 300 shown in FIG. 3, since it is a cut retaining wall formed by cutting the pre-stacked earth and sand, there is a rock wall inside the grid 310 than in the case of the support part 300 shown in FIG. The length can be formed relatively short, but instead, a separate fixing member 320 is inserted into the rock wall 1 and the end of the grid 310 is connected with the fixing member 320 to form the support part 300, so the support part ( 300) has the advantage of being able to increase the bearing capacity.

Here, the fixing member 320 is connected to the end of the grid 310 and can have any shape as long as it is a means capable of fixing the end of the grid 310, and in the case of the corrugated steel plate wall according to the present invention, the fixing member 320 ) may be composed of any one of anchoring, soil nail, and earth anchor.

In addition, the outer wall 100 may be inclined or disposed perpendicular to the ground, and the length of the grid 310 may be the same.

In addition, as shown in FIGS. 2 and 3 , a plurality of grids 310 are installed to be spaced apart from each other at regular intervals along the height direction of the outer wall 100 , and the grid 310 goes downward along the height direction of the outer wall 100 . It is preferable that the separation distance between the 310 is gradually shortened.

This is because the soil acts as a larger load toward the plate surface of the outer wall 100 by gravity as it goes down the stacked soil, so that even if a large load acts, the outer wall 100 stably supports the soil. This is so that the grid 310 is installed.

However, in the case where the width of the soil is stacked to become narrower toward the upper side, the separation distance between the grids 310 is not gradually shortened because the earth pressure does not increase significantly toward the lower side along the height direction of the outer wall 100. can also be formed.

As shown in Figure 4, a fastening hole is formed through the plate surface of the corrugated steel plate 101, the bolt 120 is installed to protrude through the fastening hole, and the nut 130 in the protruding part of the bolt 120. is fastened, the bolt 120 is fixed to the plate surface of the corrugated steel sheet, the eye nut 140 having a circular ring is fastened to the end of the bolt 120, and the end of the grid 310 is fixed to the eye nut 140 It is effective to be

By fastening the bolt 120 and the nut 130 to the area where the corrugated steel plate 101 overlaps each other, the fastening force between the corrugated steel plate 101 and the neighboring corrugated steel plate 101 can be improved, and the eye nut ( Since 140 is fastened to the end of the bolt 120 and the grid 310 is fastened to the eye nut 140 and installed, there is an effect that the grid 310 can be easily and quickly constructed.

In addition, the bolt 120 is preferably fastened to the protrusion of the corrugated steel sheet 101 which protrudes toward the inclined or inclined surface and the corrugated steel sheet 101 overlaps with the adjacent corrugated steel sheet.

As the bolt 120 is fastened to the protrusion of the corrugated steel sheet 101, the grid 310 is connected to the protrusion of the corrugated steel sheet 101 by the nut 130 to support the corrugated steel sheet 101 as a result. It has the effect of effectively preventing the deformation of the corrugated steel sheet 101 from occurring due to the earth pressure due to the load of the corrugated steel plate 101, thereby increasing the bearing capacity.

It is more stable to connect the grid 310 to the protrusions of the corrugated steel sheet 101 because the tensile strength at the protrusions among the protrusions and depressions is greater than the compressive strength at the concavities in the bending of the corrugated steel sheet 101. Because it can support the soil with

The construction method of the corrugated steel plate wall according to an embodiment of the present invention having such a configuration is as follows.

First, the corrugated steel sheet 101 is installed in two rows along the edge of the slope or the slope on which the soil is stacked to form the inner space 110 between the corrugated steel sheet 101 and the corrugated steel sheet 101 .

Then, the compaction operation is performed after the soil is filled into the inner space 110 between the corrugated steel sheet 101 and the corrugated steel sheet 101, and this operation is performed until the inner space 110 is filled with more than a certain amount of soil. It is effective to reinforce the bearing capacity of the entire plate surface of the corrugated steel sheet 101 by repeatedly performing the filling and compaction operations.

And, when a certain amount of soil or more is filled in the internal space 110 during the process of repeatedly performing the above process, the grid 310 is connected to one side of the corrugated steel sheet 101 and the grid 310 is inserted into the stacked soil. It should be carried out so that it can be extended and placed.

After the installation of the grid 310 at a certain height is completed, the soil is filled again on the upper surface and the compaction operation is performed, the grid 310 is installed again, and the process of performing the compaction operation after filling the soil on the upper surface It is effective to repeatedly proceed so that the soil is completely filled in the internal space (110).

Here, when the rock wall 1 is present inside the slope or slope, the fixing member 320 is allowed to penetrate into the inside of the rock wall 1, and the end of the grid 310 is the fixing member 320. It is preferable to improve the bearing capacity of the corrugated steel sheet 101 by being fixed to the end.

As described above, the fixing member 320 is connected to the end of the grid 310 and can have any shape as long as it is a means capable of fixing the end of the grid 310, and is fixed in the case of the corrugated steel sheet wall according to the present invention.
