METHOD OF CONSTRUCTING SHIELD FOR PROTECTING RIVERBANK AND / OR BOTTOM}
[10] The present invention relates to a river bank and / or a bottom protective barrier film forming method, which prevents the river water from being lost in the river bank and / or the floor, and prevents the river bank from being collapsed due to weakening of the river bank. It relates to the order film forming method.
[11] Unlike the recent increase in the use of water, there are many disasters caused by water caused by flooding and the like. Accordingly, in order to prevent disasters while increasing the use of water, existing natural river banks and / or floors are maintained and artificially formed river banks and / or floors.
[12] Conventionally, there have been a gabion method, a concrete retaining wall method, and a continuous order wall forming method as a method for forming a river bank and / or a floor.
[13] The gabion method has been widely used in the past because it reduces the friction of river streams and / or the bottom of the river bank and prevents scour. However, when the river water penetrates the banks or the floor, the river banks may become soft and collapse. .
[14] The concrete retaining wall construction method was able to erect the dikes vertically and allow the streams to flow into the lower part of the stream as it flows quickly without penetrating or outflowing the bottom surface. However, grooves may occur in the retaining wall of the concrete by the hydration reaction. In this case, the stream water flows out through the grooves, and the outflowed river water may cause scour phenomena and outflow of the soil in the concrete retaining wall, thereby causing the river bank to collapse. . In addition, the calcium (Ca) component, which is an alkaline component generated in the hydration reaction of cement, is included in the river water, but the calcium (Ca) component has a problem of destroying the natural river ecosystem.
[15] The continuous order wall forming method is widely used in recent years, by forming a continuous order wall among the river banks to prevent the stream water from penetrating and outflow of the river banks, it is possible to prevent the river banks from collapsing. However, the continuous order wall forming method has a problem that can not prevent the river water penetrates underground through the river bottom. Therefore, the stream created by the continuous order wall forming method could be a dry stream without water in the stream at a low flow rate.
[16] Therefore, the above-described prior art could not increase the ordering capacity by preventing the flow of river water while reducing the risk of collapse of the dike.
[17] Accordingly, an object of the present invention is to apply a fiber solid plate having excellent durability and degree of ability to the river banks and / or the floor as described above to prevent the river banks and / or floor sedimentation due to friction of the streams. It is to provide an embankment and / or a bottom protective order film forming method.
[18] In addition, another object of the present invention is to provide a river embankment and / or a bottom protective barrier film forming method for preventing the river water to penetrate the river bank and / or the floor to be lost, and prevent the collapse of the river bank and / or the floor to prevent collapse. It is.

[2] Figure 2 is a second embodiment of the river bank and the bottom protective film forming method according to the present invention,
[3] Figure 3 is a third embodiment of the river bank and the bottom protective film forming method according to the present invention,

[5] Explanation of symbols on the main parts of the drawings
[6] 10: gravel 20: geotextile
[7] 22: geotextile tape 30: nozzle
[8] 40: mixed solution 50: fiber solid plate
[9] 60: impregnation container 70: river bank and floor
[19] The river bank and / or the bottom protective barrier film forming method according to the present invention includes a laying step of laying geotextiles on the surface of the river bank and / or the bottom; And a spraying step of spraying the solidified mixed solution including the ceramic solidifying agent on the surface of the geosynthetic fiber by a shotcrete method; and a solidifying step of allowing the solidified mixed solution sprayed in the spraying step to be solidified.
[20] Here, in order to ensure that the geosynthetic fiber is strongly attached to the slope of the river, after the laying step, it may further have a support step of installing a support means for fixing the geosynthetic fiber to the river bank and / or the bottom. In addition, the solidified mixed solution does not actually mix well when the ratio of the ceramic solidifying agent is 10% or less, and when the ratio of the ceramic solidifying agent is 80% or more, it is too thin to properly function as the solidified mixed liquid. Therefore, the solidified mixed solution is preferably characterized in that 10 to 80% by weight of ceramic solidifying agent and 20 to 90% by weight of water are mixed.
[21] In addition, the river bank and / or bottom protective water film forming method according to the present invention, the impregnation step of impregnating the geosynthetic fiber into an impregnation container containing a solidified mixed solution; A laying step of laying the ground fiber impregnated with the solidified mixed solution which has undergone the impregnation step on the surface of the river bank and / or the bottom; And a solidifying step of allowing the solidified mixed solution of the geosynthetic fiber impregnated with the solidified mixed solution placed in the laying step to be solidified.
[22] Here, the support step of installing the support means for fixing the geotechnical fiber to the river bank and / or the bottom, after the laying step, so that the geosynthetic fiber to a strong attachment to the slope of the river; And supporting means for applying the surface of the support means with a mixed solution. In addition, the solidified mixed solution does not actually mix well when the ratio of the ceramic solidifying agent is 10% or less, and when the ratio of the ceramic solidifying agent is 80% or more, it is too thin to properly function as the solidified mixed liquid. Therefore, the solidified mixed solution is preferably characterized in that 10 to 80% by weight of the ceramic hardener and 20 to 90% by weight of water are mixed.
[23] On the other hand, the protective barrier film produced by the river bank and / or the bottom protective barrier film forming method is semi-permanent, even if the raw material is exposed to the natural environment for a long time as an inorganic adhesive, it is semi-permanent, and also the river bank and / or bottom protective barrier film Is not released from the water and works well up to the riverbed. In addition, since the raw material of the protective barrier film is an inorganic system, even if some components of the protective barrier film is mixed with water, it can be said to be an environmentally friendly method that is harmless to the natural ecosystem.
[24] Nonwoven fabrics are also preferred as geotextiles for use in laying riverbanks and / or bottoms. Here, the nonwoven fabric is soft, and impregnated with a ceramic hardener in the nonwoven fabric has high strength and durability of 300 kgf / cm 2 or more higher than that of concrete. Therefore, the river banks and / or the floor protection barriers prevent the river banks and / or the floor breakage due to water current contact, and the river banks have a small permeability of less than 1 × 10 ^-8 cm / sec. And / or inhibit penetration into the floor. In addition, river banks and / or floor protection linings do not change in the natural environment even with ultraviolet rays, and do not deteriorate. If necessary, a variety of colors can be realized by adding a pigment, which is eco-friendly and simple to construct. I will say.
[25] Hereinafter, the configuration and operation of the present invention in detail.
[26] In general, the construction of river banks and / or floors has a gabion method or concrete retaining wall construction method used to stabilize the bottom of the river banks. However, since the scour phenomenon occurs in the river bank and / or the bottom constructed by the above method, and the soil is leaked, the river bank is easily broken and collapsed.
[27] In order to prevent the outflow of soil by the scour phenomenon, the nonwoven fabric which is a geotextile is used as a reinforcement in a soft ground or a scour area.
[28] Cement, meanwhile, has been used for a long time in the civil engineering field and is an excellent material with much verification for its material. By the way, the cement has a strong alkali component (pH 12 ~ 13) and the particle size of the cement is larger than the fiber spacing of geotextiles.
[29] Therefore, cement cannot penetrate into the nonwoven fabric which is a geotextile, and cement and geotextile cannot be used together because the alkaline component of the cement degrades the nonwoven fabric.
[30] The fiber solidifying plate is a ceramic solidifying agent mixed with water, and the mixed ceramic solidifying agent is solidified after impregnating a long fiber nonwoven fabric which is a geotextile. The ceramic hardener is present here as fine powder.
[31] The fiber-solidified plate thus manufactured is highly durable and has a very low coefficient of permeability.
[32] In addition, the method of forming a protective barrier film made of a fiber solidified plate on the river bank and / or the bottom, the fiber solidified plate prepared in a predetermined standard in advance in the river bank and / or the entire floor, and the non-woven fabric in advance to the river bank and And / or installed on the floor and then sprayed with the ceramic solidifying agent by shotcrete. As described above, the protective membrane formed of the fiber solidification plate according to the present invention is easily installed on the river bank and / or the bottom.
[33] Here, in the case of laying the fabrication plate prepared in advance on the river bank and / or the bottom, the sides of the fiber solidification plate and the fiber solidification plate is not attached, but after cutting the nonwoven fabric and impregnated in the ceramic solidified mixed solution to make a geotextile tape Attaching the geotextile tape between the sides of the solidified nonwoven fabric plate and the solidified nonwoven fabric plate. At this time, the part attached to the geotextile tape will exhibit the same performance as the solidified nonwoven fabric plate after drying.
[34] In addition, river banks and / or bottom protective barriers are not broken and oxidized even when anchors or nails are used to fix non-woven fabrics such as fiber solid plates or geotextiles. Does not occur. In addition, since the fiber-fixed plate and the nonwoven fabric have flexibility, it is easy to paste, cut, and the like. Therefore, the riverbank and / or the bottom protective barrier film according to the present invention are easy to install in the field.
[35] Ceramic hardener has a low permeability coefficient and 10 times higher tensile and flexural strength than concrete's permeability, tensile strength and flexural strength. In particular, ceramic hardeners are not damaged by impacts at 7 × 10 ^-6 per inch at low temperatures, and there is little damage due to underwater loads when ceramic hardeners are installed in water. Hardly ever.
[36] In addition, the fiber-reinforced plate produced using the nonwoven fabric is not damaged at flexural strength of more than 180N / cm, it is possible to cut, anchoring at the time of continuous joint construction in the field. In addition, even if a portion of the fibrous plate is broken at the time of installation, if the nonwoven fabric is impregnated with the solidified mixed solution and then the nonwoven fabric is adhered to the broken portion of the fibrous plate, the broken portion of the fibrous plate is repaired.
[37] River banks and / or floor protection barriers form river banks and / or floor protection barriers that provide superior water resistance and durability, while preventing river water from entering river banks and / or floors, and by river banks and / or floors. To prevent scour from occurring.
[38] The present invention will be described in detail through the following examples. However, these examples are for illustrative purposes only and the present invention is not limited thereto.

Then, the connection between the adjacent fiber solidified plate 50 and the fiber solidified plate 50 is covered with a civil fiber tape 22, and the solidified mixed solution 40 is sprayed from the nozzle 30 used for the shotcrete method. The tape 22 is impregnated with the solidified mixed liquid 40.
[42] Then, after a certain time (about 30 minutes of the solidified mixed solution is solidified), the fiber fixing plate 50 is integrated by the geosynthetic tape 22 to form a protective shielding film, wherein the protective shielding film is formed Lay gravel (10) on the bottom of the river.
[43] On the other hand, a support means such as an anchor (not shown) can be used for a specific portion of the fiber solid plate 50. When the support means covers the geosynthetic fiber tape and sprays the solidified mixed solution 40 to solidify, the support means are not rusted or corroded so that the fiber solid plate 50 and the river embankment and the bottom bank ( 70) makes the connection between them stronger.
[44] Example 2
[45] Figure 2 is a second embodiment of the river bank and the floor protection method according to the present invention. First, instead of covering the geotextile tape 22 and spraying the solidified mixed solution 40, the geotextile tape 22 impregnated in the solidified mixed solution in advance is formed of the adjacent fiber solidified plate 50 and the fiber solidified plate 50. It is the same as Example 1 except that it covers the connection part.
[46] The fibrous solid plate 50 may be manufactured to interlock with each other, and the river bank and the floor 70 may be replaced with an architectural structure such as a building. In other words, it can be constructed in buildings.
[47] Example 3
[48] Figure 3 is an embodiment 3 of the river embankment and floor protection method according to the present invention.
[49] Referring to Figure 3, first, the geotextile 20 is laid on the surface of the river bank and the bottom 70. At this time, the geosynthetic fibers 20 are laid so as to be in close contact with each other, and may be laid so as to overlap each other slightly.
[50] Then, the solidified mixed solution 40 is sprayed on the top of the laid geotextile 20 by the shotcrete method.
[51] After that, when a predetermined time (about 30 minutes of the solidified mixed solution is solidified) has elapsed, a protective liner made of the fiber solidified plate 50 is formed on the river bank and the bottom 70.
[52] Then, the gravel 10 is placed on the bottom of the protective barrier film.
[53] On the other hand, in order to reinforce the connection between the fibrous plate 50 and the river bank and the bottom 70, a support means such as an anchor (not shown) may be used for a specific portion of the laid geotextile 20. In this case, after the geotextile 20 is laid, support means are provided. Thereafter, the solidified mixed solution 40 is also sprayed on the geotextile 20 and the support means to solidify. Thereby, the support means are not rusted or corroded, which makes the connection between the fiber solid plate 50 and the river bank and the bottom 70 stronger.
[54] Example 4
[55] Figure 4 is an embodiment 4 of the river embankment and floor protection method according to the present invention.
[56] Referring to Figure 4, first, in the impregnation container 60 containing the solidified mixed solution 40, the geosynthetic fiber 20 is impregnated in the solidified mixed solution 40, the civil fiber 20 impregnated in the solidified mixed solution 40 ) Is installed on the surface of the river bank and the bottom 70. The geotextiles 20 impregnated in the solidified mixed solution 40 are laid so as to be in close contact with each other if possible.
[57] After that, when a predetermined time (about 30 minutes of the solidified mixed solution is solidified) has elapsed, a protective liner made of the fiber solidified plate 50 is formed on the river bank and the bottom 70.
[58] When a vibrator (not shown) is installed in the impregnation cylinder 60, a protective liner made of a fiber-fixed plate 50 having a higher strength when solidified is formed.
[59] Then, the gravel 10 is placed on the bottom of the protective barrier film.
[60] On the other hand, in order to reinforce the connection between the fibrous plate 50 and the river bank and the bottom 70, a support means such as an anchor (not shown) may be used for a specific portion of the laid geotextile 20.
[61] At this time, in the case where the fiber solid plate 50 is fixed to the support means after the fiber solid plate 50 is installed, the solidified mixed solution in the upper region of the support means to prevent the upper region of the support means from rusting or corroding. Impregnation 40). In addition, when the fiber solid plate 50 is installed and at the same time the fiber solid plate 50 is fixed to the support means, the upper region of the support means is naturally impregnated with the solidified admixture 40 so that the upper region of the support means is rusted or Corrosion is prevented.
[62] On the other hand, in Examples 1 to 4, the solidified mixed solution 40 was used in which 50% by weight of ceramic hardener and 50% by weight of water were mixed. The ratio of the ceramic hardener and the water may be changed depending on the site conditions, the strength of the fiber solid plate 50, the required permeability coefficient, and the like.
[63] In Examples 1 to 4, the protective barrier film is formed on the river bank and the bottom, but may be formed only on one of the river bank and the river bottom.
[64] In Example 1 to Example 4, the protective shield membrane is installed by connecting the one side and the bottom of the river bank, it can be installed with both sides of the river bank and the bottom connected.
[65] Since the protective shielding film can be implemented in any color, it is possible to improve the landscaping property by implementing a color suitable for river banks and / or floors.
[66] After installing the protective barrier, the gravel was placed on the bottom of the river embankment, but in addition to the gravel, gabions, etc., can be applied to the protection method conventionally used, and gravel and gabion can also be placed on the side of the river embankment. have.
[67] In the present invention, in place of existing river banks and / or floor stabilization and ordering work, non-woven fabrics are used as a matrix, and a solidified admixture mixed with a ceramic solidifying agent (modeling powder) in water is sprayed by shotcrete to protect against excellent durability and durability. The method of forming the water repellent film on the river bank and / or the bottom has various effects that are superior to the prior art.
[68] (1) The construction can be freely maintained in any river bank and / or floor form, and the ground and protective barriers can penetrate into the lower river bank and / or the bottom soil as well as the nonwoven fabric with sprayed solidified mixed solution. Integrated construction further enhances durability.
[69] (2) The protective shielding film combines the flexibility of nonwoven fabric with the specificity of ceramic hardener, so it is excellent in strength, durability, water permeability, freeze-melting resistance and chemical resistance, and it is non-flammable, stable to fire, color can be implemented and landscaping is possible. outstanding.
[70] (3) The construction method is simpler and more economical than the existing construction method, and the protection barrier can prevent the flow loss of river water by the impermeable layer and prevent the river bank and / or the floor collapse due to the river bank and / or the ground penetration. .
