Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a molded structure for industrial materials.

More specifically, the present invention relates to a molded structure in which a material such as powder, liquid, gas, or a mixture thereof is confined and enclosed in a fabric mold.

[Conventional technology]

BACKGROUND ART Conventionally, as a method for obtaining a molded product of earth and sand or concrete, a fabric formwork in which earth and sand or concrete is enclosed between two layers of fabric is known. However, the molded product obtained using this fabric form is not satisfactory in terms of strength, thickness, appearance quality, etc., and a number of problems remain.

That is, the unevenness is severe, the surface lacks flatness, the difference in maximum and minimum thickness is small, so the strength at the minimum thickness is weak, and the overall thickness is not uniform, resulting in uneven strength. Furthermore, there are problems such as deterioration of appearance quality. Note that in order to increase the strength of the minimum thickness portion, the maximum thickness portion becomes thicker than necessary, requiring a large amount of material, and increasing costs. Moreover, these molded products have a limit in thickness, and there are problems such as the inability to obtain a thick-layered molded product.

This cause is due to the fabric formwork.

In other words, conventionally known fabric formwork has been proposed in which upper and lower layers of fabric are partially connected at predetermined intervals both vertically and horizontally in order to regulate the thickness. are connected and fixed using connecting materials such as bolts and strings, and the vertical and horizontal installation spacing and connection length can be adjusted depending on the thickness. , it is difficult to adjust the thickness of the connecting material,
It tends to be of uneven thickness. In particular, when the knot is fixed using a string or the like, the knot stretches too much, making it difficult to set and make the thickness uniform.

In addition, the strength of the connecting and fixing portion is low, and it may break and cause uneven thickness, resulting in poor appearance. On the other hand, fabric car frames in which upper and lower two layers of fabric are connected at the same time using bonding threads at predetermined intervals both vertically and horizontally during the fabric manufacturing stage can only be obtained with an interlayer thickness of a maximum of a few feet, making it difficult to form high-thickness fabrics. Manufacturing was impossible.

Therefore, in order to obtain a thickly layered molded product, the distance between the connecting parts connecting the upper and lower layers must be increased both vertically and horizontally so that the planar direction of the mold is reduced (i.e., area shrinkage occurs) when filling the filler. By increasing the thickness in the vertical direction, that is, by making the base convex portion extremely thick compared to the thickness of the upper and lower connecting portions, the thickness was increased by an average value. This is because the shrinkage of the cloth formwork causes severe surface irregularities and uneven thickness, making it impossible to obtain a molded product with sufficient strength, shape, etc.

In order to solve these problems, Japanese Patent Publication No. 49-48206 is known. This is a woven fabric in which the alternating warp threads connecting the upper and lower layers are woven into the ground structure between the joints of each layer, and are lengthened appropriately so that they are longer than the ground warp threads. After growth, by separating the upper and lower layers,
The thickness is increased by moving an appropriate length in the ground weave in the thickness direction, but this is because the alternating warp threads that connect the layers slide on the ground weave, resulting in a uniform thickness at each connection point. cannot be set, and essentially only molded products with uneven thickness, uneven strength, and poor shape can be obtained.

In addition, even when increasing the thickness, there is a limit to the amount of weaving in an appropriate length within the interval between the connecting parts, making it difficult to obtain a molded product with the desired thickness.

Therefore, in order to increase the thickness, as in the past, the distance between the connecting parts in the vertical and horizontal directions (especially in the vertical direction) is expanded to increase the amount of appropriate length of alternating warp threads, but the The molded product may have uneven surfaces, non-uniform thickness, poor shape, uneven strength, etc. due to formwork shrinkage due to the expansion of the spacing between parts, and the fabric formwork is also not sufficiently easy to handle. I can not say.

[Problem that the invention seeks to solve]

The present invention has been completed through intensive research in view of the above problems.

That is, the object of the present invention is that the earth and sand or the inorganic hardened material
To provide a molded article structure which is confined and enclosed by a cloth formwork and has a high surface flatness, high dimensional uniformity, good appearance shape, and a thick layer. It is.

[Means for solving problems]

The object of the present invention is to provide a fabric mold formed from a multilayer fabric having a joining thread for joining layers, and at least one of the multilayer fabrics.
A molded structure consisting of a filled layer of earth and sand or a hardened inorganic material filled between two layers, the surface of which is provided with predetermined joint points vertically and horizontally to form a large number of convex parts, This is achieved by a molded article structure using a fabric mold, characterized in that the shape of the convex portions and the distance relationship between the joining points satisfy the following conditions.

qζ Bottom margin The molded product structure of the present invention is one in which a material is enclosed in a fabric mold made of at least two upper and lower layers of fabric and integrally molded, and the enclosed material is a fabric and a fabric. It has a molded structure whose shape is maintained uniformly by the restraint of the upper and lower joining threads between the layers, and is a thick layered product with a thickness of up to 1000 fl.

Hereinafter, the structure of the molded article structure of the present invention will be explained based on the drawings. FIG. 1 is a plan view of the molded structure, in which (a) shows the bonding points of the upper and lower layer fabrics in a regular arrangement, and (b) shows the bonding points of the upper and lower layer fabrics in a staggered arrangement. Fig. 2 is a model diagram for showing flatness, and Fig. 3 is an overall view of the XX cross section of Fig. 1 (a).These figures are examples of the molded structure of the present invention. It is a schematic diagram for explaining.

As shown in FIG. 4, the molded structure of the present invention comprises an upper layer cloth 1
A material 10 is constrained and enclosed in a fabric mold made of a large number of joining threads 6 for joining the lower layer cloth 1' and the upper and lower layer cloths 1, 1'. Point 2.2'
It is molded integrally with a fabric formwork in a shape that expands outward from the base point.

In the present invention, this molded structure has a surface flatness (
Z) but tanoo z≦ta! It satisfies 125°.

In Figures 1 and 2, P is AB, CD and AC,
For BD, h is the thickness calculated at the maximum point 0 of the convex portion with reference to the horizontal line of AB, CD, AC, or BD. Although FIG. 2 is a model diagram showing an example in one direction for calculating flatness (Z), this condition must be satisfied in both directions, that is, AB or CD and AC or BD.

Since the angle θ shown in Fig. 2, that is, the ratio of h to P, is extremely small, the molded structure in this recess has excellent appearance quality with extremely flat surface unevenness, and is strong. It will also be stable. Furthermore, the molded product structure has almost the same dimensions as the initial size of the fabric formwork, that is, before filling with the material 10, with almost no shrinkage of the fabric formwork.

Since Z=tanQ' becomes ho, the molded structure has ideal flatness, but the fabric fJ! When using a formwork, fabric elongation, fabric formwork deformation, etc. occur to some extent, so this is not practical. In addition, at Z(ta++25°), h becomes extremely dog-like, so the surface is highly uneven and flat.

This cannot be said to be preferable because it lacks strength and appearance quality, and furthermore, the fabric formwork is greatly deformed. This means that the shrinkage of the fabric formwork before and after material encapsulation is large, that is, the initial distance between adjacent bonding points of the fabric formwork before material encapsulation (Pa) is compared to the distance between adjacent bonding points after material encapsulation (P). When 2 becomes small, the molded product expands outward by an amount commensurate with the dimensional change, and the substantial thickness increases and P decreases. In addition, even when there is no contraction of the fabric formwork (i.e., p, = p), if the fabric elongation is a dog, the amount corresponding to the fabric elongation will expand outward, even if there is no change in real P. Since h increases, 2 becomes extremely sharp, and the molded product becomes more uneven.

Furthermore, the configuration of the present invention has the advantage that the ratio of the thickness to the distance between adjacent junction points (
α) satisfies α=1 to 20, and the dimensional uniformity (β) within one molded structure satisfies β=0.8 to 1.2. In addition, the value of T is after enclosing material 10,
Immediately, the measurement is carried out by inserting a hard wire, etc. However, if the material 10 is solidified or hardened, the thickness measured from the outside at the point O of the maximum convexity where the material 10 expands is determined by h as shown in Fig. 2.
The value obtained by subtracting twice the measured value shall be adopted. αn, α
is the distance P between each adjacent junction point, as shown in FIG.

/n. still.

The α value T/P is calculated not only based on the distance between adjacent junction points in one direction, but also in both the vertical and horizontal directions, and each must satisfy the above conditions.

The molded structure in this range has a thickness T that is equal to or greater than the distance between adjacent joint points, that is, the thickness T is large regardless of the distance P between adjacent joint points.
This results in a nearly flat molded structure with little outward expansion and extremely small surface irregularities. Furthermore, since the dimensional uniformity within one molded structure is within a certain range, the overall surface flatness, thickness, dimensional stability of the distance between adjacent joints, shape stability, and strength stability are sufficiently maintained. This results in a molded structure that satisfies the following.

It should be noted that outside the above range, that is, α, the thickness is smaller than the distance P between adjacent junctions (conversely speaking, the distance P between adjacent junctions is larger than the thickness T), so the degree of outward expansion is This is not preferable because the molded structure has a large surface roughness. Also, α>20 is for the distance P between adjacent junction points,
Since the thickness T becomes too thick, the molded product cannot be formed into a stable structure due to poor shape.

In addition, when β < 0.8 or β > 1.2, the distance P between adjacent joint points causes dimensional non-uniformity of the thickness T, resulting in a molded product structure that is stable in terms of overall dimensional uniformity, shape, strength, etc. I can't connect with my body.

Furthermore, in the molded structure of the present invention, the dimensional relationship and area of the convex portion in the vertical and horizontal directions are PW'' (0.8 to 1.2).
-PF and pw-PF = 100 to 100,00
It satisfies 0m2.

The molded structure in this range has approximately the same distance between adjacent joint points in the vertical and horizontal directions, so it has a nearly square shape, so the external shape is extremely uniform and good. Furthermore, by regulating the distances between adjacent joints vertically and horizontally, a stable and well-balanced molded structure can be obtained.

In addition, outside the above range, that is, PW < 0.8 PF or P
W) At 1.2PF, the vertical and horizontal distances between adjacent joint points are in a υ rectangular state with large differences, resulting in an extremely non-uniform appearance and poor appearance. Moreover, the thickness cannot be balanced in the vertical and horizontal directions, and the strength is also biased in one direction, making it impossible to obtain a desirable molded structure. Also, PvV-
In PF (]OO-, the distance between adjacent bonding points is too narrow and the number of bonding threads increases, making it difficult to fill with material and obtain the desired molded structure.PW-PF
>] OO,000IllII+2 has a vertical and horizontal distance between adjacent joints that is too large, so it expands outward and has a very uneven surface, resulting in an A molded structure, which is not dimensionally stable. It is no longer possible to obtain a molded structure with a high temperature.

The molded article structure made of the cloth formwork of the present invention configured as described above has a uniform thickness and strength with a flatness with little unevenness as a whole, and has a good external shape. This results in an unprecedented molded structure with a thick layer.

Note that the molded structure of the present invention has a substantially uniform thickness throughout;
Although it is a molded product having a shape, a single filter point may be partially installed as a drainage hole, and the material 1 provided to improve the filling property of the material 10.
A hose guide for zero charging may be installed, and
A single wall may be installed to reduce the pressure resistance of the fabric formwork, and the contents thereof are not strictly limited.

Further, the material 10 used in the present invention is not limited to earth and sand, concrete, etc., but may be powder, liquid, gas, etc., and the configuration of the fabric formwork may be changed depending on the purpose of use, contents, etc. The molded structure of the present invention can be obtained by making changes.

In addition, the fabric form used for the molded product structure of the present invention has a predetermined joint in a plurality of joints between a joining thread that joins layers at predetermined intervals vertically and horizontally, and a thread that intersects with the joining thread. By physical external force, thermal or chemical treatment,
A multilayer of a predetermined size, made of yarn that can be released from the joint with the joining thread without substantially damaging the joining thread, and in which the joining thread and the fabric are partially or fully fixed. The periphery of the cloth is closed, and a plurality of injection ports for filling the material are provided. Therefore, the cloth used may be a woven fabric or a knitted fabric, and the number of layers may be two layers, three layers, etc.

Hereinafter, an example in which a multilayer fabric is used in the fabric form used in the present invention will be described in detail.

The fabric form used in the present invention is made of a multilayered fabric having joining warps that partially join the layers at predetermined intervals vertically and horizontally.

The joining warp yarns are alternately woven into the upper and lower layer cloth based on a predetermined plan, and intersect with the weft yarns in each layer to form a plurality of joints. The interlacing of the warp and weft for joining at the joint section is such that one or more wefts intersect with I! However, there are various types of textures, and there are no particular limitations.

In the margin text below, a joint refers to a part where the joining warp and weft intersect, or are organized, and release refers to the part where the joining warp and weft intertwine, or unravel, the weft that forms the joint. The reed, that is, the joining warp and weft intersect e
(Organization) and become loose.

Also, the release of the joint by physical external force refers to powder and granular materials.

Breaking of the weft due to the filling pressure or filling load when filling with liquid, gas, or a mixture thereof, or breaking the cotton thread using a jig means pulling out the cotton thread, and releasing the joint by chemical treatment Degradation of the weft by liquid or steam means to dissolve and destroy it.

In this configuration, the above-mentioned interlacing (texture) is canceled by the above-mentioned physical external force, S-type or chemical treatment on the weft, and these canceling means, seen from the weft side, break or melt the weft. , melting or drawing.

In other words, the breaking method is to use a weak yarn with low tenacity as the weft yarn and cause it to break due to external force1. (using the spreading force that separates the layers by inserting a jig or by the filling pressure of the material).

In addition, the melting method uses a low melting point dissolvable thread as the suture thread, which is melted and destroyed by heat. For example, low-melting fibers such as polyolefin, polyvinyl chloride, and polyvinylidene chloride are used and are melted and destroyed by heating.

As for the dissolving method, a highly soluble dissolving yarn is used as the weft yarn, and the weft is dissolved and destroyed by liquid or steam. For example, polyvinyl alcohol, polyacrylic, cellulose fibers, etc. are used to dissolve and destroy them in water.

In addition, as for the pulling method, the weft is made to have a weaving structure such as a floating structure or a ring structure, so that pulling out by external force is completely eliminated.

For example, by using bundled fiber yarns such as monofilament or twisted yarn with good lubricity, and creating a floating weave structure between the joints in the width direction, it can be hooked by hand or using a mechanical hook method. Remove it and it will disappear.

In this configuration, by releasing the joint, the joining warp released from the joint is provided to the adjacent joining warp by sliding from itself or through the joint of the layer opposite to the released layer. , or a combination of the above, it becomes possible to separate the upper and lower parts to a desired distance.

The thickness between the separated upper and lower layers must be at least twice the initial (at the time of weaving) upper and lower layer thickness. By selecting, initial (h, time of completion)
It is possible to obtain a desired thickness several times to several tens of times or even hundreds of times.

The fabric formwork used in the present invention can maximize the thickness between the upper and lower layers separated by release even if the initial (at the time of weaving) thickness between the upper and lower layers is small; The larger the thickness between the upper and lower layers (at the time of weaving), the easier the release action is, the easier it is to increase the thickness, and the better the quality can be obtained.

Therefore, the thickness between the upper and lower layers of the initial M (at the time of weaving) is at least 3
m, preferably 10 mg or more. If the thickness is less than 3m, the weft yarns are often removed to make the layer thicker, and as it is difficult to remove the weft yarns, the fabric after removal becomes poor, making it difficult to obtain a satisfactory product and quality. Can not.

In addition, in this configuration, when the joint is released or used as a third product after release, the joining warp slides over the entire length direction of the fabric formwork (lengthwise direction of the first product),
Since thickness unevenness occurs between layers, in order to prevent this, the coefficient of friction between the joining warp and the fabric is improved to prevent the joining warp from sliding.

As a measure to prevent slipping, the joining warp is a yarn with unevenness such as a different-shaped yarn, a different denier yarn, a twisted yarn, or a yarn whose surface is covered with fluff, and in some cases, a treated yarn such as a resin-treated yarn or a rubber-treated yarn is used. One theory is to increase the yarn density of the ground warp on both sides of the joining warp, or to use yarns having the same form as the joining warp. Alternatively, the yarn density of the ground weft at the joint of the non-released part is increased, or a yarn having the same form as the joining warp is used. Alternatively, the joining warp and the ground weft can be made into a plain weave structure at the joint of the non-released part, or the joining warp and the ground thread can be bonded with resin, rubber, adhesive tape, etc.
Alternatively, by fusing, fixing with seams, etc.), the slippage of the joining warp threads is reduced or eliminated, and any material may be used as long as it can achieve this purpose. It is not limited to.

The fabric formwork used in the present invention having the above configuration is as follows:
At the weaving stage, at the stage of an intermediate product finished to a certain size, or at the stage of manufacturing a blank product during filling, the interlacing (Mi starvation) at the joint is canceled and the layer [I star] is removed.
ll can be separated to a desired distance. The stage at which the release is to be released may be appropriately selected depending on the intended use, content, use, etc. of the cloth formwork, and is not particularly limited.

In addition, the fiber used for this fabric formwork is cotton.

Natural fibers such as linen and wool, metal, glass, inorganic fibers such as carbon fibers, cellulose, regenerated fibers such as tongue and lace fibers, cellulose, polyamide, and polyester.

Polyolefin, polyurethane, polystyrene.

Polyvinyl chloride, polyvinylidene chloride, polyacrylic,
There are synthetic fibers such as polyvinyl alcohol-based fibers, and the fiber forms include long fiber yarns, spun yarns, and round cross-section yarns, as well as regular circular cross-section yarns and irregular cross-section yarns.

There are foamed yarns, connosed yarns, L-date yarns, etc., and there are various fiber diameters.There are no particular restrictions on the use, and these fibers can be used alone or in combination, and they can also be processed through physical processing, chemical processing, etc. These conditions may be selected as appropriate depending on the purpose of use, content of use, use, etc. of the cloth formwork.

Further, in this structure, the paper structure, weave form, etc. are not particularly limited; for example, the structure is plain weave.

It may be a twill weave, a satin weave, or a variation thereof, and the number of layers may be two, three, four, etc. structure entirely or partially. It is legal to use the present invention alone or in combination with other bonding methods (partial bonding between layers, maintaining spacing, or covering both layers). Often, the configuration contents of these conditions are appropriately selected depending on the purpose of use, content of use, use, etc.

The fabric form used in the present invention is made by sewing or otherwise closing the periphery of the multilayer fabric having the above structure, and providing a plurality of injection ports for filling material on the surface to a predetermined size. .

In addition, this fabric formwork can be made by polymerizing and integrating other fabrics, knitted fabrics, non-woven fabrics, nets, etc., or by attaching other parts, or by undergoing physical processing, chemical processing, etc. to improve handling. It can be used to improve product functions, etc., and there are no particular limitations on its use. These conditions may be appropriately selected and adopted depending on the purpose of use, the content of use, etc.

Figure 4 is a cross-sectional view of the structure of the cloth formwork before the mineral layer, and Figure 5 is a plan view of FIG. 4, and FIG. 6 is a cross-sectional view of the structure of the fabric formwork after the mineral layer has been formed.

In FIG. 4, the joining warp threads 6' are alternately woven through the upper and lower layer fabrics 1.1' to have an initial (at the time of weaving) thickness t. That is, the joining warp 6' partially intersects with the weft of each layer 1.1', and on the upper layer fabric 1 side, 2 m = 2

Margin below 〔Example〕 Examples of the present invention will be described below.

Example 1 Two-layer fabric in which the initial thickness between the upper and lower layers was set to 20 mm (the ground warp and ground weft of each layer were Ny840d x 22 pieces/I
In n), joining warps (Ny 30,000 denier twisted chrysanthemums) are arranged in the upper and lower layers to join the lower layers at intervals of 100W in the width direction, and release joints are provided at intervals of 100 gourds in the length direction, and the joints are For the weft, rayon spun yarn 20/2s is used for one joining warp, three each for the upper and lower layers, and the joining warp and rayon spun yarn are crossed 6 times in the upper and lower layers to form 7 loops.
Repeatedly, a two-layer fabric with the same structure as shown in Figures 3 and 4 was created with the Sfi width on both sides of the joining warp at a high density (Ny840dX40 threads/in), and the periphery of the fabric was sewn. A fabric formwork (width 2 m x length 5 m) with an injection port attached to the surface was laid on the slope, and after fixing with anchors, fluid concrete with a water/cement ratio of 65% was poured using a pump. As a result of filling the rayon yarn while cutting it under pressure of about 1 atmosphere, a concrete molded structure with a uniform thickness, few irregularities, and a good shape was obtained as shown in Table 1.

Example 2 Two-layer fabric in which the initial thickness between the upper and lower layers was set in the order of 30 (the ground warp and ground weft of each layer were PP 1000 dX20 pieces/1
n), bonding warp threads (PET 50,000 denier twisted yarn) for bonding the interlayers at intervals of 180 m in the width direction are arranged in the upper and lower layers, and release joints are provided at intervals of 180 m in the length direction, and the joints are For the weft, paper plates (approximately 2ooa) are used for one joining warp, 7 each for the upper and lower layers, and the joining warp and paper thread are interlaced 14 times at the top and bottom of 4" and looped 15 times. Repeatedly, the 10mm width on both sides of the warp for joining is made by combining different types of ground warps with high density (cotton yarn 7/2 s'X 25$7'I
After making a two-layer fabric according to item n), immersing the fabric in water, inserting a holding tool into the fabric and cutting the paper string to release the release joint, the surrounding area is closed by sewing. , and a fabric formwork (width 2 m x length 5 m) with an injection port attached to the surface,
A chain block was set up on a leveled gently sloped surface, and fluid soil with a water/soil ratio of 50 cm was pumped and filled from the injection port, resulting in unevenness with a uniform thickness as shown in Table 1. A molded structure that forms artificial soil with a good shape and a small amount of dirt was obtained.

Example 3 A two-i fabric in which the initial thickness between the upper and lower layers was set to 20-2 (the ground warp and ground weft of each layer were Ny420dX50'2;/
In), joining warps (Ny2500d) for joining the upper and lower layers are arranged in the upper and lower layers at intervals of 60 m in the length direction, and release joints are provided at intervals of 60 m in the length direction.
The joint is made by using two water-soluble vinylon yarns (100 d) as wefts for one joining warp, two for each layer above and below, and crossing the joining warp and water-soluble vinylon yarn four times in the upper and lower layers. A two-layer fabric is made by repeating it in a loop shape five times, and the front and back sides of the fabric are coated with rubber.The periphery is then sealed with rubber glue, and an injection port is attached to the end to make it airtight. A flexible fabric formwork (width 1.5 m x length 10 m) was placed on a flat surface, water was pumped through the injection port, and the aqueous vinylon solution was dissolved and sealed at approximately 0.25 atm. As a result, as shown in Table 1, a water body molded structure having a uniform thickness and a good shape with few irregularities was obtained.

Example 4 Two-layer fabric with the initial thickness between the upper and lower layers set to 20Im (the ground warp and ground weft of each layer are Ny840dx28 pieces/1n
), joining warp threads (Ny840d) for joining the upper and lower layers are arranged in the upper and lower layers at intervals of 20+m in the width direction, and joints for group division are provided in a staggered manner at intervals of 20m in the length direction (Fig. 1
In the same form as in (B)), the joining part uses two acetate threads (50 denier) as wefts for one joining warp, two each for the upper and lower layers, and connects the joining warp and acetate thread to the upper A two-layer fabric is made by interlacing four times in the lower layer and repeating it five times in a loop shape. After applying rubber coating to the front and back sides of the fabric, the periphery is glued and closed with rubber glue. Press air into an airtight fabric mold (width 1.5 m x length 10 m) with an injection port attached through the injection port, and seal the air at 0.5 atm while cutting the acetate thread. As a result, as shown in Table 1, a 58M air-integrated molded structure with a uniform thickness and a good shape with few irregularities was obtained.

Comparative Example 1 In the configuration of Example 1, the joining warp was not prevented from sliding, and both sides of the joining warp were made with the same ground density (Ny840d).
As a result, as shown in Table 1, as shown in Table 1, a molded structure with severe unevenness, uneven thickness, and defective shape was obtained.

Comparative Example 2 In the configuration of Example 1, the joining warp yarns were arranged at 50W intervals in the width direction, release joints were provided at every 200W intervals in the length direction, and the other parts were the same and the concrete IJ-t was enclosed in the same manner. As a result, as shown in Table 1, a molded structure with severe unevenness, uneven thickness, and defective shape was obtained.

Comparative Example 3 In the configuration of Example 1, the joining warp is 400+ in the width direction.
As shown in Table 1, as shown in Table 1, as shown in Table 1, the concrete was placed in a shape with severe unevenness and uneven thickness, with joints placed at intervals of 400 m in the length direction, and with concrete encapsulation in the same manner. This resulted in a defective molded structure.

Comparative Example 4 Two-layer fabric with the initial thickness between the upper and lower layers set to 20+Ia (
The ground warp and ground weft of each layer are N)'840dX22/
In), joining warps (Ny 10,000 denier) for joining the upper and lower layers are arranged in the upper and lower layers at intervals of 50 meters in the width direction, and are provided at intervals of 200 meters in the length direction, and the joining warps are 80 in the center within the geological structure between longitudinal joints.
■A two-layer fabric with a length 1.5 times the length of the ground warp threads is created in a loop shape, the fabric is closed by sewing, and an injection port is attached to the surface of the fabric mold. A frame (width 2m x length 5m) is laid on the slope and fixed with anchors, then fluid concrete with a water/cement ratio of 65g is pumped at a pressure of approximately 1 atm to form a loop within the ground structure. As a result of filling the molded structure while sliding the joining warp yarns retained therein in the thickness direction, as shown in Table 1, a molded structure with severe unevenness and an uneven overall thickness was obtained.

〔Effect of the invention〕

The molded article structure using the cloth formwork of the present invention has the following characteristics due to the configuration described above.

(1) The surface has excellent flatness and a good external shape.

(2) Since the thickness is uniform throughout, the strength is stable.
