DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a fabric form for slope protection vegetation.

[0002]

2. Description of the Related Art As is well known, a slope form protection fabric form is superior in terms of workability and economical efficiency to a river revetment work or a mountain slope protection work, as compared with a conventional concrete form work form. , Already has many construction records. Usually, such a cloth mold is a sheet-like body composed of a cylindrical two-layer cloth part and a one-layer cloth part partially connecting the two-layer cloth part, and the periphery thereof is made of a fluid such as concrete or mortar. It is closed so that the body can be poured.

Conventionally, a cloth mold has been laid on a slope at a slope protection work site, and fluid mortar or concrete or the like is communicated from an injection port provided in a tubular double-layered cloth portion above a sheet-like body. It was poured into a cylindrical two-layer cloth part and solidified to form a legal frame. In this fluid injection process, the one-layer cloth portion of the cloth mold, the filling pressure of mortar and the like, the weight of the filling material, and the stress generated by the expansion due to the injection of the mortar and the like of the two-layer cloth portion, etc., It functions so as to maintain each double-layered cloth portion in the sheet-like body at a desired position and in a desired shape, and to arrange a state in which a fluid is injected and dispersed in each double-layered cloth portion to form a uniform legal frame. . Therefore, after the mortar or the like injected into the two-layer cloth is solidified and the form of the cloth mold is fixed, most of the one-layer cloth which fulfills the above function becomes unnecessary and is cut off with a knife or scissors. The opening obtained by resection was used for vegetation base.

[0004] The work of cutting off the single-layer cloth portion at the construction site of the cloth formwork is a work on a slope, requires a great deal of labor, and is a difficult work involving danger. In addition, it is not easy to cut the opening so that the opening obtained by cutting has a uniform shape over the entire surface of the sheet-shaped body. There was a problem that it was easily damaged.

SUMMARY OF THE INVENTION An object of the present invention is to provide a fabric mold capable of solving the above-mentioned problems of the conventional fabric mold. That is, an object of the present invention is to provide a sloped vegetation cloth mold which is excellent in workability and economy, is excellent in form uniformity of a stake frame, and can exhibit an excellent aesthetic appearance as a vegetation base.

[0006]

Means for Solving the Problems In order to achieve the object of the present invention, the present inventors have repeatedly studied focusing on the function of a single-layer cloth portion of a cloth mold, and have made trial production and trial production of a cloth mold. As a result of repeating the evaluation by the construction test of the frame, the present invention was completed. That is, the present invention provides: A sheet-like body comprising a cylindrical two-layer cloth part and a one-layer cloth part having an opening by partially connecting the two-layer cloth part, the periphery of which is closed. 1. A fabric form for slope vegetation, characterized by formation of a wearing tissue. 2. A fabric mold for slope vegetation, wherein the heat-fused tissue at the inner peripheral edge of the opening according to the above item 1 is a tissue formed by irradiation with a carbon dioxide gas laser beam. 3. The fabric mold for slope vegetation according to the above 1 or 2, wherein the opening is formed in a shape similar to the shape of the outer peripheral edge of the one-layer cloth. A step of weaving a sheet-like body having a single weaving part that partially connects the double weaving part to the double weaving part so that an identification band is formed at the center of the single weaving part, and reading the position of the identification band on the sheet-like body By coupling with a step of cutting most of the single-woven portion from the sheet-like body with a carbon dioxide laser cutting machine equipped with a means capable of indicating a cutting range based on it,
A sloped-vegetable cloth formwork, characterized in that the single-woven portion has an opening and a sheet-like body having a heat-sealing structure formed on an inner peripheral edge of the opening.

Hereinafter, the present invention will be described in more detail. The cloth formwork according to the present invention is a sheet-like body comprising a tubular two-layered cloth part and a single-layered cloth part partially connecting the two-layered cloth part. The cylindrical two-layer cloth portion may be formed into a cylindrical shape at the time of manufacturing a sheet using a two-layer cloth, or may be formed into a cylindrical shape by post-processing. In other words, the tubular portion of the two-layered fabric portion is formed by forming a desired portion of the two-layered fabric into a single-layered fabric by suturing, bonding, fusing, etc., and forming a desired closed space between the two-layered fabrics. May be achieved by

In the present invention, a sheet-like body in which a tubular two-layer fabric portion and a single-layer fabric portion are integrally woven and knitted on a weaving / knitting machine is preferred. Among these, the sheet-like body in which the cylindrical double weaving part and the single weaving part are integrally formed by the loom, because the form uniformity of the lawn frame when used as a cloth mold for slope vegetation is more excellent, Particularly preferred. The fabric forming the fabric frame according to the present invention may be selected from a woven fabric, a knitted fabric, and a non-woven fabric according to the condition of the slope, and may be used. However, a particularly preferred fabric in the present invention is a woven fabric having a double woven portion and a single woven portion integrally woven.

[0009] The sheet-like body of the present invention forms a bag-like body whose periphery is closed, and is provided with an injection port in an arbitrary upper two-layer cloth part, between the two-layer cloth parts communicating at the slope protection site. Is formed so that a fluid filler such as mortar or concrete can be injected into the voids, and the injected filler such as mortar solidifies and can be used as a legal framework.

The one-layer fabric portion of the fabric mold according to the present invention partially connects the two-layer fabric portions to be formed into a legal frame, and after the legal frame is formed, the legal frame has regularity and exhibits an aesthetic appearance. The arrangement on the sheet is not particularly limited. The shape of the outer periphery of the single-layer cloth portion is not particularly limited in the present invention, and any shape such as a circular shape, a square shape, a hexagonal shape, and an octagonal shape may be used.

However, when a fluid such as mortar is injected into the cloth mold according to the present invention, the dispersibility of the mortar or the like into the gaps of the two-layer cloth and the uniformity of the shape of the obtained method frame are more excellent. Thus, in the present invention, a cloth mold in which the outer peripheral edge of the single-layer cloth is circular or hexagonal is particularly preferably used. The one-layer fabric portion of the fabric mold according to the present invention has an opening, and a heat-sealing structure is formed on an inner peripheral edge thereof.
The opening is formed by cutting most of the single-layer cloth portion from a sheet having a two-layer cloth portion and a single-layer cloth portion or a sheet having a cylindrical double-layer cloth portion and a single-layer cloth portion. Although the heat-fused tissue of the present invention may be formed in a step after cutting most of the cloth portion, it is more preferable to form the heat-bonded structure at the same time as cutting.

[0012] The heat-fused structure in the present invention comprises a heat-sealed portion obtained by heating thermoplastic polymer fibers constituting the inner peripheral edge of the opening to a temperature equal to or higher than the melting point thereof and heat-sealing at least between adjacent fibers. . In the present invention, it is particularly preferable that the heat-fused portion is formed over the entire inner peripheral edge of the opening. The heat-fused tissue according to the present invention can also be formed by cutting most of the sheet-like body single-layer cloth portion with scissors, a knife, or the like, and then partially heating the inner peripheral edge of the obtained opening. . However, when cutting with scissors or the like, at the time of cutting or after cutting, the fiber structure forming the opening tends to be disturbed such as fraying and deformation, and it may be difficult to form a desired heat-sealed structure after cutting. . Therefore, in the present invention, it is particularly preferable that the one-layer cloth portion is cut off in a non-contact manner by irradiation with a carbon dioxide gas laser beam, and the heat-sealed portion is formed simultaneously with the cutting.

The opening of the single-layer cloth portion of the cloth mold according to the present invention is preferably formed in a shape similar to the shape of the outer peripheral edge of the single-layer cloth portion. This is because, when the opening thus obtained is used as a vegetation base of the stake, the excellent aesthetic appearance can be achieved. The fabric mold of the present invention is made of a thermoplastic synthetic fiber, and specifically, a polyester fiber, a polyamide fiber, an acrylic fiber, a polyvinyl fiber, or the like can be used.

When the fabric form according to the present invention is obtained by weaving, a sheet having a double woven portion and a single woven portion partially connecting the double woven portion may be obtained by a conventionally known weaving method. The loom used at this time is not particularly limited, and may be a dobby device, a tappet device, or the like. However, in order to achieve the object of the present invention, using a jacquard device, a sheet having a double weave and a single weave or a sheet having a cylindrical double weave and a single weave are integrally formed. Weaving is particularly preferred. In addition, weft insertion during weaving may be done with rapier,
Other shuttle looms may be used.

In order to obtain the fabric mold of the present invention more economically, it is more preferable to perform the weaving in the weaving step so that the identification band is formed substantially at the center of the single weaving portion. By providing the identification band, it is possible to perform the opening forming step by cutting off the single woven portion following the weaving step almost automatically and more efficiently. The identification band in the present invention may be formed so as to be distinguishable from other portions of the single-woven portion. Preferably used in the present invention, during weaving, using a colored yarn different in color from other warps and wefts for some warps and wefts, the colored yarns do not appear in the surface texture of the double-woven portion. The weaving is performed so that the colored yarn appears on the back fabric and that the colored yarns of the warp and the weft intersect at a preferably central portion of the single woven portion to form an identification band at an intersection. One or two colored yarns may be used.

In the present invention, the position of the identification band in the sheet is read, and most of the single-woven portion is cut off by a carbon dioxide laser cutting machine provided with means capable of indicating a cutting range based on the position. A particularly preferred fabric mold according to the present invention, which is a sheet-like body having an opening in a single-woven portion and having a heat-fused structure formed on the inner peripheral edge thereof, can be obtained.

In the fabric mold according to the present invention, an opening is provided in the single-layer cloth portion without substantially disturbing the structure of the single-layer cloth portion formed after fabric production, and the fiber structure of the single-layer cloth portion is highly maintained. In this state, at least the adjacent fibers are fused and solidified to form a heat-welded structure on the inner peripheral edge of the opening. Therefore, when used as a sloped fabric form, a single layer of the fabric is cut off. The same function as or more than the above-described function of the single-layer cloth portion in the non-cloth mold can be exhibited. That is, when the fabric mold of the present invention is laid on the slope and fluid mortar or the like is injected from the injection port provided in the two-layer cloth portion, the mortar or the like is almost uniformly applied to each of the two-layer cloth portions. It is possible to disperse and inject into the fabric, and it is unlikely that an undesired positional change of the two-layer fabric portion occurs.Although it is a sheet-like body having an opening portion in the single-woven fabric portion, it is connected by the single-woven fabric portion. It is difficult to recognize that the two-layer cloth portions are deformed due to twisting or the like, and has excellent workability. Therefore, the form frame is extremely excellent in form uniformity, and a uniform opening can be easily formed, so that a cloth mold that can exhibit an excellent aesthetic appearance as a vegetation base can be obtained.

The use of the fabric form according to the present invention eliminates the need for a conventional work of cutting off the fabric portion at the work site, thus making it possible to carry out the slope protection work safely, promptly and at low cost.

840 denier / 1 of the same type as the weft, using this single twisted yarn
Using a 40 filament non-twist yarn, weaving was performed with a Jacquard machine to obtain a sheet having a double woven portion and a single woven portion and having a weave width of 150 cm. The loom was operated at 330 times / min, and the weft was inserted in a rapier manner.

As a woven fabric, a circular single woven portion having a diameter of 80 mm is arranged at a distance between peripheral edges of 190 mm in the width direction of the sheet, and at a distance of 55 mm in the length direction of the sheet.
A sheet-like body in which the next row of single-woven portions was staggered was obtained. In addition, two black colored yarns, two each for the warp and the weft, were woven at the center of each single weaving part so as to form an identification band at right angles.
The density of the obtained woven fabric was a warp density of 21 threads / inch and a weft density of 23 threads / inch. Then, the woven sheet was cut into a carbon dioxide laser cutting machine (ML1516) manufactured by Mitsubishi Electric Corporation.
FC, oscillator output 800 W), the cutting range of the single weave portion is determined based on the position of the black identification band, and the laser is formed so that an opening having a diameter of 60 mm and the same center as the single weave portion is formed in each single weave portion. Cutting was performed to form a heat-welded portion in which fibers adjacent to the inner peripheral edge of the opening of the single-woven portion were fused and solidified. The thickness of the end of the fused portion is increased compared to the periphery,
This indicated that adjacent fibers were fused, coalesced, and solidified. A sheet having a width of 450 cm and a length of 700 cm was sewn with a sewing machine to obtain a sheet having a width of 150 cm. An injection port was provided in the two-layer woven portion above the sheet-like body to obtain a fabric mold according to the present invention.

The obtained mold was laid on a slope having a slope of 35 °, and mortar of 1: 2 was injected from the injection port with a hose using a pump truck. The injected mortar was almost uniformly injected into each of the double-woven portions, and the casting was able to be completed with almost no offset from the lower part of the mold to the upper part. After the mortar was solidified, the legal frame formed in each of the two-layer woven portions also had an extremely uniform shape.

Further, the single weave portion opening has the same shape,
It was in a state where it could be expected to exhibit an excellent beauty as a vegetation base.

[0024]

Comparative Example 1 The cloth mold of this comparative example was obtained in exactly the same manner as in Example 1 except that the single woven portion of the obtained sheet was cut with scissors without using a carbon dioxide laser cutting machine. I got the frame. Further, mortar was poured and poured into the cloth mold of the present comparative example under exactly the same conditions as in Example 1.

When the mortar is injected, in the mold of the present comparative example, the boundary yarn between the double woven portion and the single woven portion is frayed, the double woven structure is disturbed, and the mortar leaks in the two-layer woven portion at 10 or more places. confirmed. In addition, the shape of the opening of each double-woven portion and each single-woven portion after mortar injection was also uneven,
It has been confirmed that the cloth mold that can achieve the object of the present invention cannot be used.
