The present invention relates to a water sheet fiber sheet formwork for reinforcing the slope surface to prevent erosion or loss of soil on the slope filled with water, more specifically, the block formed by the fiber sheet formwork solves erosion and leakage at the same time Concrete or mortar must be filled throughout the fiber sheet formwork, and the load is spread evenly over the entire area when the lower and upper fibers contacting the slope are filled evenly over the entire area, and the upper fiber does not swell only in some areas. A vertical binder fiber is further provided to connect the lower fiber and the upper fiber in the vertical direction in the vertical direction, and the horizontal binder fiber is connected vertically and vertically in the transverse direction of the slope, and in particular, the lower fiber and the upper fiber are fabric or In weaving with knitted fabrics, fiber density It relates to a fiber sheet formwork which weaves a small and swelling fiber band and a fiber band with a large fiber density and alternately weaves a fiber band with a relatively small swelling degree.

In addition, the present invention, when the leak and erosion prevention block is cured in a special terrain with a lot of protrusions or curved portions, a cap is generated between the ground and the block, and after a long time, a fault due to cutting or breaking occurs due to gravity Therefore, the present invention relates to a water sheet fiber sheet formwork in which reinforcing members such as pipes, reinforcing wires or wires are installed between the lower fibers and the upper fibers in the longitudinal direction to increase the durability of the blocks.

Typically, the slopes are formed to prevent the loss of rivers or roads by wind or rain, and then the bulky stones are cut or processed to a suitable size to accumulate stones. Alternatively, by stacking concrete blocks of various types, the soil of the inclined surface is prevented from collapsing or being washed out in rainy weather.

However, to accumulate stones, the work takes a long time, and it is necessary to cut or process heavy stones, and to develop materials to secure the material, which can cause other environmental damage such as natural damage and scattering dust. In addition, there is a risk in safety accidents, and the cost of repair and maintenance of the masonry is high.

In addition, in order to stack the concrete block, such as the work takes a long time, as well as the engagement of the block must be accurate, but the engagement decreases over time, the maintenance cost due to the chain breakage of the revetment structure during heavy rain It takes a lot.

Therefore, the shoreline reinforcement of slopes using high-strength geotextiles is used for shorelines such as shorelines of various rivers, shorelines of agricultural drainage, slopes of roads or railways, slopes of dams or reservoirs, and banks of coastal or reclaimed land. .

The revetment method using a fiber band is a method of constructing a concrete reinforcement or revetment surface by injecting uncured concrete or mortar with a high pressure concrete pump between circular textile formwork made of high-strength geotextile. to be.

In the revetment method using a fiber band, the formwork is a permeable cloth, and the surplus mixed water of the flowable concrete or the mortar is discharged by the injection pressure of the pump to form a hardened body of concrete or mortar having a high hardening time and high density and high strength.

Such a construction can be easily installed on land as well as underwater, and formwork is a covering material, so that even in a complicated gradient, the surface can be closely adhered to the terrain to form a concrete or mortar mat with a uniform thickness.

Construction using this method is disclosed in Korean Patent Publication (Publication No. 10-0280958) and Japanese Patent Publication (JP-A-7-207669). The revetment method is to install the fabric prepared in accordance with the site topography in advance, and to inject concrete or mortar with a high-pressure pump to form a concrete or mortar mat of a wide area within a short time to the conventional site-cast concrete method or precast block method Compared with the quickness, stability, construction efficiency and economic efficiency, it has a remarkable working effect especially in underwater construction. In addition, the fiber band revetment method is widely used in the revetment construction because it is constructed with a large area as compared to other construction methods, because it is excellent in robustness and hardly any soiling is pushed out.

However, since the upper fabric and the lower fabric are simply connected by fixed yarns, there is a sufficient space for the concrete or mortar to be injected between the upper fabric and the lower fabric, but when the load is concentrated as the concrete or mortar expands There is a problem that the durability is weak to support this.

In addition, although the curved area is severe and the fiber band is closely adhered to the curved terrain depending on the site, the fracture surface may be generated due to the weight of the concrete or mortar due to the long time use after the concrete or the mortar is filled and cured. It can also be.

In addition, according to the fiber band, even if it is suitable in a lakeside structure where water is constantly filled, such as a reservoir or solder, it is possible to waste resources by filling concrete or mortar in the whole fiber band unnecessarily in a place where water is relatively small. Therefore, when trees or the like are to be planted between the fiber bands according to the deformation of the terrain conditions, they cannot be used interchangeably.

Accordingly, the present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to form a erosion prevention block for water barriers, such as river banks, weaving fiber sheet formwork filled with concrete or mortar In this case, the density of the fiber is formed discontinuously and repeatedly to provide a water sheet formwork for strengthening the durability of the fiber.

Another object of the present invention is to fill in between the binder fiber itself connecting the lower fiber and the upper fiber in contact with the inclined surface in a zigzag form or by arranging the lower fiber and the upper fiber itself in a staggered manner. It is to provide a water sheet fiber sheet formwork that effectively distributes the load of the resulting moldings.

Another object of the present invention is a water sheet fiber sheet formwork having a separate reinforcing member to prevent a single layer is generated by the cap between the ground and the water leakage and erosion prevention block is installed on a special terrain with high protrusions or curved portions To provide.

It further includes a reinforcing member interposed between the lower fiber and the upper fiber in the transverse or longitudinal direction to increase the tensile strength against the break in the longitudinal direction of the water leakage erosion block.

The lower and upper fibers are discontinuously woven with fibers of different densities.

The degree of swelling by the moldings filled between the lower density and the upper fibers is less than the amount of swelling by the moldings filled between the lower density and the upper fibers.

The fibers are composed of woven fabrics, the high density fibers are woven into a plain weave intersecting the weft yarn and the warp one by one, and the low density fibers are the woven or twill weaving where the weft and warp intersect two or more.

The fiber is composed of a knitted fabric, and the high density fiber has a higher density of the nose where the V-shaped nose and the semi-circular nose intersect and are less elastic than the low density fiber.

The binder fiber is a longitudinal binder fiber extending in the inclined direction of the inclined surface, and connects the lower fiber and the upper fiber of the large fiber band.

The longitudinal binder fibers intersect in an X-shape by connecting the high density fibers of the upper fibers and the high density fibers of the neighboring lower fibers in the repeatedly formed high density fibers and the low density fibers.

The lower fiber and the upper fiber are disposed to be offset so that the high density fiber of the lower fiber and the low density fiber of the upper fiber are mutually matched, and the longitudinal binder fiber connects between the high density fiber of the lower fiber and the high density fiber of the upper fiber, Intersect in the form of an X.

The binder fiber further includes a horizontal binder fiber extending perpendicularly to the vertical binder fiber, and the lower fiber and the upper fiber are formed with cross bars having a constant thickness by the horizontal binder fiber in the horizontal direction.

The reinforcing member is provided between the lower fiber and the upper fiber of the low density fiber.

The reinforcing member is any one selected from pipe, rebar, wire or rope.

A fiber sheet formwork for filling a concrete or mortar molding material to reinforce a slope and curing a leak erosion prevention block for preventing leakage, wherein the lower fiber is in contact with the slope and the lower fiber corresponds to the upper portion of the lower fiber. And a plurality of filter portions interconnecting the lower fibers and the upper fibers so as to be in contact with each other, the upper fibers filling the molding material between the lower fibers, and not filling the molding material when the molding materials are filled, and in the longitudinal direction of the leak erosion prevention block. It includes a reinforcing member interposed between the lower fiber and the upper fiber in the longitudinal direction to increase the tensile strength against fracture.

The filter unit is a water-permeable fabric or knitted fabric that prevents leakage and erosion of the soil but can pass freely.

The reinforcing member is a rebar or wire that can be bent to suit a variety of block shapes.

According to the water sheet fiber sheet formwork according to the present invention having such a configuration there is an advantage that the molding of the immersion and erosion prevention block is easy, and the durability is increased.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the method for installing the erosion protector using the water film fiber sheet formwork according to the present invention having the configuration as described above in detail.

As shown in Figure 1 and 2, the fiber sheet 100 of the present invention, the lower fiber 110, a predetermined width and width, abutting the inclined surface and woven into a woven or knitted fabric, and corresponds to the lower fiber 110 And an upper fiber 120 that is woven from the same or similar material as the lower fiber 110. Accordingly, the fiber sheet 100 forms a block by filling the concrete or mortar other molding 130 between the lower fiber 110 and the upper fiber 120.

At this time, when the concrete or mortar other molding 130 is injected between the lower fiber 110 and the upper fiber 120, one side in the curing process of filling the concrete or mortar with the lower fiber 110 of the fiber sheet 100 As the concrete or mortar is concentrated and the load is concentrated and the upper fiber 120 is swollen, it is necessary to adjust the height between the lower fiber 110 and the upper fiber 120 to distribute the load as a whole and form a flat block. have.

Therefore, in the embodiment of the present invention by discontinuously weaving fibers of different or regular density to the lower fiber 110 and the upper fiber 120 to increase the degree of expansion by concrete or mortar in relatively large fibers and small fibers Differently, the molding 130 regulates the height so as not to bulge only on one side, by means of connecting the lower fiber 110 and the upper fiber 120 using a relatively dense fiber.

The fibers are repeatedly extended from low density fibers having a normal fiber density and relatively high density fibers, and in the low density fiber bands 112 and 122, concrete or mortar other moldings 130 are greatly inflated, and high density fibers In the stages 114 and 124, it can be seen that the concrete or mortar and other moldings 130 are inflated smaller than the low density fibers.

The fiber sheet 100 is composed of a woven or knitted fabric. In the case of forming the fabric, the fabric is generally composed of a plurality of tissues by a method of intersecting the weft yarn and the warp yarn. For example, the high-density fiber is composed of a plain weave in which the weft yarn and the warp cloth cross one by one. It can be composed of twill intersecting two by two or vertical figure intersecting more. Alternatively, in the case of forming a knitted fabric, the knitted fabric consists of a wale corresponding to the top and bottom of the V-shaped nose, a semi-circular nose to the left and a right, and a course corresponding to the weft of the fabric. The nose is formed, for example, high density fibers mold the nose tightly, flat and stretchless, and low density fibers can loosely, convex and stretch the nose.

As illustrated in FIG. 2, the vertical binder fibers 140 may be further provided in single or plural (not shown) to vertically connect the high density fibers of the lower fibers 110 and the upper fibers 120 vertically. In addition, as shown in Figure 3, while connecting the high-density fibers of the lower fiber 110 and the upper fiber 120 up and down, it can be configured to cross the binder fiber 140 in the X-shape, not shown Although not, a plurality of intersecting binder fibers 140 may be formed. In addition, as shown in FIG. 4, the lower fiber 110 and the upper fiber 120 are formed such that the high density fiber band 114 of the lower fiber 110 and the low density fiber band 122 of the upper fiber 120 correspond to each other. When displaced, the binder fiber 140 connecting the high density fiber band 114 of the lower fiber 110 and the high density fiber band 124 of the upper fiber 120 naturally crosses in an X shape.

Meanwhile, as shown in FIG. 5, the fiber sheet 100 of the present invention repeatedly forms long and high density fibers and low density fibers in the longitudinal direction, which is the inclined direction of the slope, as described above, and at the same time, the lower fibers 110 in the horizontal direction. And horizontal binder fiber 150 may be further installed to connect the upper fiber 120. Therefore, it can be seen that the crosspiece 152 is formed in the horizontal direction, and the unevenness is formed in the horizontal direction by the crosspiece 152.

In addition, in the embodiment of the present invention, as shown in Figure 7, when the filling and curing of the concrete sheet or mortar other molding 130 to the fiber sheet 100 in a special topographical conditions, to some extent the fiber sheet 100 and the molding Since the 130 is flexible, it is not limited to the topographical conditions, but in the topographical conditions with many protrusions or curved portions, a large space is generated between the ground and the fiber sheet 100, and after curing, it is cut or broken by the gravity of the block. There is a concern, it is further provided with a reinforcing member 160 to solve the shortcomings caused by the incision surface and the fracture surface, causing a large accident.

The reinforcing member 160 is installed to extend the fiber sheet 100 in the longitudinal direction or the horizontal direction, it is possible to use a pipe or reinforcement or a wire, rope or the like with excellent durability. The reinforcing member 160 passes through the fiber sheet 100 in the longitudinal direction, but as shown in FIG. 6, the lower fiber 110 and the upper fiber (lower density fiber bands 112 and 122) of which sufficient space is secured as much as possible. Although it is preferable to pass between the 120, as shown in Figure 7, when the longitudinal binder fibers 140 are installed so as to cross each other, the lower fibers 110 and the upper fibers (high density fiber bands 114, 124) It is preferred to install between 120).

In another embodiment of the present invention, the water barrier fiber sheet 200 does not always reach a constant level of water, such as agricultural waterways, reservoirs, or river banks, and is installed in a variable condition according to seasons and precipitation, and thus the entire slope No need to fill with concrete or mortar.

Therefore, as shown in FIGS. 8 and 9, the fiber sheet 200 includes a plurality of filter parts 212 and 222 connected at one side to the lower fiber 210 and the upper fiber 220 at one side, and the lower portion of the fiber sheet 200. In the area where the fiber 210 and the upper fiber 220 are joined by the filter parts 212 and 222, the concrete or mortar other molding 230 is not filled, but only in the remaining areas except for the filter parts 212 and 222. As a form of honeycomb and other various forms of blocks.

In this case, the filter parts 212 and 222 are woven into a woven or knitted fabric, so that the water can pass freely, but the leakage and erosion of the earth and sand laid on the bottom of the block can be prevented, and the filter parts 212 and 222 can be prevented. It is possible to minimize the specific gravity of the molding in the block. In addition, when the water level is not high due to changes in the environment, the filter may be cut to fill the sac on the filter parts 212 and 222 and to plant trees and the like.

In this case, a reinforcing member 260 such as a pipe, reinforcing wire or a wire may be installed between the lower fiber 210 and the upper fiber 220 except for the filter parts 212 and 222 to strengthen the durability of the block in preparation for breaking of the block. Can be. In another embodiment of the present invention, as the reinforcing member 260, it is preferable to use reinforcing bars or wires to be suitable for various shapes of the blocks while having a diameter smaller than that of the pipes.

As described above, the present invention facilitates the molding by dispersing the load of the molding as a whole in forming the block over the entire inclined surface when water is filled in the inclined surface such as a reservoir or a levee river, and further provided with a reinforcing member. It can be seen that the technical idea of the configuration to enhance the durability of the block. Within the scope of the basic technical idea of the present invention, many other modifications will be possible to those skilled in the art.

As described above, according to the configuration of the present invention, the following effects can be expected.

First, when weaving the fiber sheet into a fabric or knit fabric, the durability of the fiber sheet is increased by repeatedly molding two kinds of fabrics or knit fabrics having different densities, and a block space is used to prevent flooding, such as a river bank. It is suitable for the case of integrally molding without any effect, and it is expected to have an effect of enhancing consumer convenience.

Second, the binder connecting the lower fiber and the upper fiber is vertically zigzag connected in the longitudinal direction of the inclined surface and vertically connected in the transverse direction of the inclined surface to distribute the load of the molding material filled therebetween evenly throughout the fiber sheet. The effect of improving the efficiency is expected.

Third, by further providing a reinforcing member between the blocks, when the block is not in close contact with the ground, there is no fear that a fault occurs due to the load, and the effect of significantly reducing the defective rate is expected.

Fourth, even when the filter sheet is formed in the middle of the fiber sheet to form an empty space in the block, by leaving the filter sheet without cutting the filter sheet, the water is allowed to pass through the slope where water is intermittently flooded. It can be prevented, so it is expected that the effect that can be modified according to the site conditions.
