Description

  The present invention is a bag material used for construction methods such as scouring prevention, erosion protection, glue covering, water control, etc. for prevention of scouring, erosion prevention, etc. on coasts, rivers, lakes, ponds, etc. More particularly, in particular, when a large number of bag materials are connected to each other, the present invention relates to a bag material that is extremely easy to connect and can avoid the displacement movement of the mouthpiece rope.

Conventionally, for the prevention of scouring and erosion prevention at coasts, rivers, lakes, ponds, etc., methods such as root consolidation, floor protection, glue covering, water control, etc. (hereinafter simply referred to as “root consolidation”). Various construction methods such as “construction method” are adopted.
In this root hardening method, a bag material (commonly known as “bottle unit”, “futon-don”) containing fillers (namely, filling materials) such as cobblestone, cracked stone, and crushed stone is used (Patent Document 1). reference). At the construction site, the bag material is filled with a certain amount of filling material and then lifted and laid at a position to be constructed.

When the bag material is lifted, the bag material has sufficient strength to withstand the load applied by filling materials such as crushed stones, cobblestones, and crushed stones at the bottom of the bag material.
By the way, the bag material can be laid and constructed in a wide area having a certain size by arranging a large number of the bag materials.
Further, in order to correspond to the flow velocity of the river, a large number of bags arranged in a line are connected to each other with a connecting rope to form a group and fixed in a stable state.

Specifically, a connection rope is connected to a suspension rope of bag material, or a method in which the connection rope is directly wound around a mouth portion of a closed bag material is used.
However, in the former method, it is necessary to connect the ropes of the suspension ropes so that they do not move and then connect them to the connection ropes, so that the connection structure becomes complicated and the knots of the suspension ropes can be unraveled extremely. Sometimes.
On the other hand, in the method of winding the connecting rope of the latter method around the mouth portion of the bag material, the mouth portion of the bag material is not stable and is not easily tied, and the connecting rope is easily displaced.
In any case, there is a problem that both methods require sufficient skill to work efficiently, and the work time is not efficient.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view schematically showing the bag material of the present invention (note that this shows a state where the filler W is not yet filled).
This bag material A has a mouth portion 11 opened upward and is slightly narrowed to form a bottom portion, which is a purse-like shape as a whole.
The bag material A includes a bag body 1 made of a knitted fabric, and a suspension rope 2 attached so as to pass through a stitch (mesh) S of the bag body 1.

The form of the knitted fabric used as the material of the bag body 1 is a Raschel knitted fabric knitted by, for example, a Raschel knitting machine, and has a large number of rectangular stitches S in a lattice shape.
As the knitting yarn for knitting the knitted fabric, synthetic fiber yarns such as polyester fiber yarns, polyamide fiber yarns and polyacrylic fiber yarns, or natural fiber yarns such as cotton yarn and hemp yarn may be used alone or in combination as appropriate. Used.

For example, as shown in FIG. 2, the bag body 1 is made of a double knitted fabric in which a central portion of a tubular knitted fabric is integrated to form a bottom portion 12, and one side is covered with the bottom portion 12 as a starting point. There is a method of forming the knitted fabric bag body 1.
The bag body 1 is filled with the filler from the mouth side, but the portion where the knitted fabric is integrated serves as the bottom portion 12 to function as a bag material.

Also, for example, as shown in FIG. 3, the bottom of the tubular knitted fabric is squeezed with a bottom-bound rope to form the bottom 12, and similarly, the bottom 12 is used as a starting point and one side is put back to form a double knitted fabric. There exists the method of forming by the method used as the bag main body 1.
Now, in the bag material of the present invention, the suspension rope 2 is inserted into the stitch S of the mouth portion of the bag body 1 and the end portions are tied to form an endless shape. It can be pulled out and can be lifted by hooking the part.
The bag body 1 includes a retaining ring 4 in the vicinity of the lower portion of the suspension rope 2, and a mouth-drawing rope 3 can be attached to the retaining ring 4.

The retaining ring 4 may be directly attached to the knitted fabric of the bag main body 1, but can be tied to the knitted fabric of the bag main body 1 through the mouth-drawing rope 3 as will be described later.
Here, as the retaining ring 4, it is sufficient if it can withstand sufficient strength when the bag materials are connected to each other,
Loops such as metal rings, fiber rope rings, and plastic rings are used.
Here, in the case of a fiber rope ring, for example, a ring diameter of about a dozen centimeters cm and a thickness (diameter) of about a dozen mm are employed.

FIG. 4 is a diagram schematically illustrating a specific example of attachment of the retaining ring 4 to the bag body. In (A), the retaining ring 4 is a metal ring, and is inserted through the knitted fabric of the bag body.
In (B), the retaining ring 4 is formed of a fiber fabric (for example, a knitted fabric or a rope), and this is also inserted through the stitch of the knitted fabric of the bag body.

FIG. 5 is a diagram schematically illustrating another specific example of attachment of the retaining ring 4 to the bag body.
In (A), the retaining ring 4 is a metal ring, which is attached to the bag body via the mouthpiece rope 3.
In this case, the retaining ring 4 is attached to the bag body 1 by inserting the mouthpiece rope 3 into the stitch and then binding the retaining ring 4 together.
In (B), the retaining ring 4 is formed of a fiber fabric (for example, a knitted fabric or a rope), and this is also attached to the bag body via the mouthpiece rope 3.
Also in this case, the retaining ring 4 is attached to the bag body 1 by inserting the mouthpiece rope 3 into the stitch and then binding the retaining ring 4 together.

FIG. 6 is a diagram schematically illustrating another specific example of attachment of the retaining ring 4 to the bag body.
Only a part of the knitted fabric is shown for convenience.
First, as shown in FIG. 6 (A), the ropes are attached so as to be entangled and the ends are connected to form a loop-shaped retaining ring 4.
In the drawing, the rope is shown as an example in which one stitch S is inserted and entangled.
In this state, as shown in FIG. 6B, when both ends of the looped rope are pulled, a pair of hook portions 4A is formed.
As shown in FIG. 6C, a pair of hooks 4A is formed by pulling the central part of the looped rope.
What is necessary is just to insert the aperture-rope rope 3 and the connection rope 5 which are mentioned later in these hook parts 4A.

FIG. 7 is a view for schematically explaining still another specific example of attachment of the retaining ring 4 to the bag body (in this case, the knitted fabric is shown as an example having a honeycomb stitch).
FIGS. 7A and 7B are examples in which the retaining ring 4 is attached to the knitted fabric of the bag body using the base rope 6.
In FIG. 7A, the base rope 6 is attached so as to be entangled with the knitted fabric, and the retaining ring 4 is attached so as to pick up only the base rope 6.
For example, the base rope 6 is shown as an example in which one stitch S is inserted and entangled.
The base rope 6 is U-shaped and has a free end.

In FIG. 7B, the base rope 6 is attached so as to be entangled with the knitted fabric, and the retaining ring 4 is attached so as to pick up both the base rope 6 and the knitted fabric.
In these cases, if a knitted fabric having a stitch of about 25 mm is used as the knitted fabric, and a polyester rope having a diameter of about 10 mm is used as the base rope 6, a bag having a retaining ring 4 (for example, a thickness of 12 mm and a ring diameter of 15 cm). The attachment strength to the main body is extremely large.

In FIG. 7C, the retaining ring 4 is attached by being inserted through a gap formed in the knitted structure of the knitted fabric.
In the knitted fabric, when the knitted structure H is knitted, the knitted fabric can be knitted so as to form a diamond-shaped or honeycomb-shaped stitch.
In this example, the knitting structure H is further knitted so as to form a gap H1, and the retaining ring 4 is inserted and attached to the gap S1.

Here, an operation method of charging the filler W into the bag material A will be described.
FIG. 8 is a view for explaining a method of filling the bag material A with a filler W such as cobblestone, crushed stone, or gravel using the mold K. FIG.
The bag material A is packed using a circular formwork K. First, the bag body 1 is held along the inner wall of the formwork K.
In this case, the mouth portion 11 of the bag material A is held along the upper edge of the formwork K.

Next, in this state, a filler W such as crushed stone is introduced into the bag material A from above (see FIG. 8A).
After feeding a predetermined amount of the filler W, six portions of the suspension rope 2 inserted through the stitches S of the bag material A are lifted by hooks (not shown) [see FIG. 8B].
In this case, the operation of the hook is performed using a crane or the like, and the bottom of the bag body A is lifted to the extent that it slightly floats from the ground to eliminate sagging of the knitted fabric of the bag body.
Since the mouth portion 11 of the bag A is narrowed down by the suspension rope 2 and reduced by the lifting of the hook, the vicinity of the lower portion is narrowed down by using the mouth rope 3 (see FIG. 8C). ].
In this case, the mouth portion 11 is closed by winding the mouth portion rope 3 around the mouth portion 11 of the bag material A. At that time, the mouth portion rope 3 is wound while being inserted into the retaining ring 4. Do times.
Since the mouthpiece rope 3 is passed through the retaining ring 4, the whole bundle of the mouthpiece ropes 3 does not move along the bag material A.

When the retaining ring 4 is already inserted through the stitch S of the bag material A as in the case of FIGS. 4A and 4B, a mouthpiece rope 3 prepared separately is taken out and used. It becomes.
As described above, when the filler W such as crushed stone is introduced into the bag material A, the bag material A is lifted, separated from the mold K, and moved to a necessary place (see FIG. 9).

  By the way, when the mouth portion 11 of the bag material A is wound and closed using the mouthpiece rope 3, particularly when the retaining ring 4 is attached via the mouthpiece rope 3, that is, the above-described FIG. In the case of (B) and (B), it is not necessary to use the mouthpiece rope 3 prepared separately, and the mouthpiece 11 of the bag A is closed using the mouthpiece rope 3 attached together with the retaining ring 4 as it is. It is good and efficient.

Since the squeezing rope 3 is wound around the mouth part 11 while passing through the retaining ring 4, the mouth squeezing rope 3 is held and fixed as a bundle by the retaining ring 4 even after the mouth part 11 is closed and moved up and down. There is nothing to do.
In addition, since the mouth squeeze rope is not attached through the knitted fabric of the bag body as in the prior art, when the opening of the bag body is squeezed, the bag body and the mouth squeeze rope are not rubbed and scratched. It is avoided that it is attached.
And there is no hassle of pulling out the mouth-drawing rope from the stitches as before.
In addition, since the squeezing rope is not inserted around the bag body, the minimum length of the squeezing rope may be sufficient.
Incidentally, troublesome insertion of a mouth-drawing rope is not required even during production, which is efficient.
Now, a large number of bag materials A filled with the filler W are arranged and laid in a certain area of the construction site, but are connected as a group using the following connecting ropes so as not to move with each other. It will be.

FIG. 10 schematically shows a group of the bag materials A that are arranged and laid.
In this example, the connecting rope 5 is arranged by a plurality of connecting ropes 5Y in the vertical direction and a plurality of connecting ropes 5X in the horizontal direction.
The mouth portion 11 of the bag material A is located just near the intersection of the connecting ropes in the vertical and horizontal directions.
By connecting the bag material A to the connecting rope 5, the bag material A is connected as a whole as a group, and it is avoided that the bag materials A are individually displaced.

FIG. 11 is a diagram schematically showing a state in which the mouth portion 11 of the bag material A is held and fixed via the retaining ring 4 and the connecting ropes 5Y and 5X.
In FIG. 11A, the retaining ring 4 is disposed at the intersection of the connecting ropes 5.
FIG. 11 (B) is an example in which the connecting rope 5 is entangled with the retaining ring 4 and stopped.
FIG. 11C is an example in which another tie rope piece 51 is tied to the connecting rope 5.

Although the present invention has been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that various other modifications can be made without departing from the essence thereof.
For example, in the above-described embodiment, the bag material A is a double knitted fabric covered with a tubular knitted fabric. However, the bag material is formed of a single knitted fabric that does not perform such covering. Of course, A can also be adopted.

Moreover, although the case where the vertical connecting rope 5Y and the horizontal connecting rope 5X are used to restrain the large number of bags A as a group, such vertical and horizontal connecting ropes 5Y and 5X are shown. As shown in FIG. 12, a plurality of bag materials A can be connected by the connecting rope 5 via the retaining ring 4.
In this case, since the bag material A at the position required by the connecting rope 5 can be sequentially connected, it can also be applied to the bag material A when they are not arranged in an orderly manner.

  The present invention relates to a bag material A that is very easy to connect and avoids displacement movement of the mouth-drawing rope 3 when a large number of bag materials A are connected to each other. The present invention can be applied to various methods such as construction methods, floor protection works, glue covering works, and water control works, and the fields of use are wide.
