Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a civil engineering sheet to be buried in soil for reinforcing soft ground, reinforcing roadbed, preventing excavation in rivers, revetment revetment, embankment reinforcement on land and coast, and for preventing drainage. Regarding

[0002]

2. Description of the Related Art For example, a civil engineering sheet such as a woven fabric, a knitted fabric, or a non-woven fabric is provided immediately below unrolled soil to be constructed on soft ground or below the embankment of a reclaimed land to reinforce or protect the ground Is being buried. However,
Since the width and length of the above sheet itself is restricted by the loom and product standards, etc., if the construction surface is large and a larger civil engineering sheet is needed, the width is tied at the factory by sewing, and a large size. It required a process of finishing. In addition, a large civil engineering sheet that is sewn is bulky even when folded, and thus requires a large space for storage.

The present invention has been made in order to solve the above-mentioned conventional problems, and not only does the connecting work for connecting the civil engineering sheets in a factory not necessary at the time of construction, but the weaving process and the connecting process are integrated. Therefore, it is an object of the present invention to provide a civil engineering sheet which can reduce the cost and further requires less space for storage.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a plurality of woven fabric sheets are joined together by alternately weaving the ears to form a single woven fabric structure or a multiple woven fabric structure to form a single sheet. The feature is to provide a civil engineering sheet.

[0005]

As described above, when the ears of a plurality of fabric sheets are alternately woven to form a single woven structure or a multiple woven structure, the woven process and the connecting process can be integrated. , More foldable and not bulky.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, 10 is a civil engineering sheet, and the civil engineering sheet 10 is a sheet 11 composed of four plain weaves,
It is formed by connecting 12, 13, and 14 in a folding screen shape or a zigzag shape.

That is, in FIG. 1, at the right end portion of the civil engineering sheet 10, the connecting end portion 20a of the first sheet 11 of the uppermost layer and the second sheet 12 of the second layer, and the third sheet 13 of the third layer and the uppermost sheet. The connecting ends 20c of the lower fourth sheet 14 are connected to each other by forming a single woven structure.

On the other hand, at the left end of the civil engineering work sheet 10,
The connecting ends 20b of the sheet 12 and the third sheet 13 are connected to each other by forming a single weave structure.

As shown in FIG. 2, the first sheet 11 and the second sheet 11
At the connecting end portion 20a of the sheet 12, the warp yarn 1 of the first sheet is
1a and 11b and warp threads 12a and 12b of the second sheet, warp threads 11a of the first sheet and warp threads 12a of the second sheet
DOO is, first on a sheet weft 1 _1, for the second sheet weft 2
Under _2, on the first sheet weft 1 _3, under the second sheet weft 2 _4, are woven so as to pass through the.., Warps 11b of the first sheet and the second sheet of warp 12b is, second under the seat weft 2 _1, the first top sheet weft 1 _2, under the second sheet weft 2 _3, on the first sheet weft 1 _4, ...
It is woven so as to pass through.

As shown in FIG. 3, the second sheet 12 and the third sheet 12
At the connecting end 20b of the sheet 13, the warp yarn 1 of the second sheet
2a, 12b and, of the third sheet warp threads 13a, 13b, the second sheet warp thread 12a and the third sheet warp thread 13a.
DOO is, 'on the third sheet weft 2 _2' second sheet weft 2 ₁ under, on the second sheet weft 2 ₃ ', under the third sheet weft 2 _4, a ... The warp threads 12b of the second sheet and the warp threads 13b of the third sheet are woven so that
Below the sheet weft 3 ₁ ′, above the second sheet weft 2 ₂ ′, below the third sheet weft 3 ₃ ′, below the second sheet weft 2
It is woven so that it passes through ₄ '...

As shown in FIG. 4, the third sheet 13 and the fourth sheet 13
At the connecting end portion 20c of the sheet 14, the warp yarn 1 of the third sheet
3a and 13b, and among the warp threads 14a and 14b of the fourth sheet, the warp thread 13a of the third sheet and the warp thread 14a of the fourth sheet.
Is the weft yarn 3 ₁ for the third sheet, and the weft yarn 4 for the fourth sheet
Under _2, third upper sheet weft 3 _3, under the fourth sheet weft 3 _4, is woven to pass ..., and warps 13b of the third sheet and the warp 14b of the fourth sheet, fourth under the seat weft 3 _1, 3 on the seat weft 3 _2, 4 under the seat weft 4 _3, on the third weft sheet 3 _4, ...
It is woven so as to pass through.

Then, as shown in FIG. 5, when the civil engineering work sheet 10 is expanded during construction, its width is quadrupled, and the connecting members 20a and 20c are on the upper side of the seat.
The connecting member 20b comes to be located below the seat.

As described above, in FIG. 1, at the right end portion (one end portion) of the civil engineering sheet 10, the connecting end portion 20a of the first sheet 11 and the second sheet 12, and the third sheet 13 and the fourth sheet 14 are connected. The connecting end portions 20c are connected to each other using a single woven structure, and the second sheet 1 is provided at the left end portion (the other end portion).
Since the connection end portions 20b of the second and third sheets 13 are connected to each other by using the single woven structure, during the construction, the first and second sheets 11 and 12, the second and third sheets 1
In addition to saving the labor of connecting the second and the third sheets 13 and the third and the fourth sheets 13 and 14 in series, it is easy to fold and is not bulky.

The connecting end portion 20a includes the upper and lower adjacent warps 11a, 11b, 12a, 12b and the weft 1.
It is woven into a single woven structure consisting of ₁ , 1 ₂ , 1 ₃ , ..., 2 ₁ , 2 ₂ , 2 ₃ ,. In this way, the weaving process and the connecting process can be integrated. The same applies to the other connection ends 20b and 20c.

Although the present invention has been described above, the present invention is not limited to the above description, and modifications and the like without departing from the scope of the invention are included in the present invention. is there.

That is, in the above description, the case where the connecting ends of four sheets are joined has been described.
It can also be applied when connecting more than three sheets or four sheets.

Further, in the present embodiment, the case where the single weave structure is used for the connection has been described, but in addition to the double weave structure, the multi-woven structure can be used for the connection.

[0018]

As described above, the present invention provides a sufficiently large civil engineering sheet by combining the ears of a plurality of fabric sheets by alternately weaving the ears to form a single weave structure or a multiple weave structure. Since it is possible to do so, it is possible to save the labor for connecting the sheet-like materials at the time of construction, and since it is easy to fold and is not bulky, it does not take up a space for storage and space can be saved.
