Abstract

PURPOSE:To improve efficiency in flood control works by a method wherein water-impermeable fins are provided to the periphery of a bag that is filled with filling substances, and gaps produced between piled-up bags are reduced with the fins. CONSTITUTION:A bag 1 is made up with flexible, water-impermeable fins 5 provided successively on peripheral parts of a filling part of the bag that is filled with heavy substances such as earth and sand or environmental purification material. The filling part 4 is filled with the heavy substances that are put through an opening 2 of the bag 1, and the opening is closed with a binder 3 like a string. As a number of such bags are piled up on the bank of a river under the state of being interposed one another by weight and pressure of the filling parts 4, gaps produced between adjoining bags 1 are shut up with the fins 5, and leakage of water can be prevented therewith.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used to purify a water environment filled with a so-called sandbag filled with heavy materials such as soil and sand, or an environmental purification material such as a shell, which is used at the time of wind and flood damage. Related to the improvement of environmental purification material filled bags.

[0002]

2. Description of the Related Art Sandbags are widely used because they are easy to handle and simple in preparation for flooding and flooding of rivers due to typhoons and heavy rain. Sandbags are generally manufactured by filling a square bag made of hemp or polypropylene fiber with a heavy material such as soil or sand, but after filling the heavy material with a chamfered shape with rounded corners. Since it is not a perfect rectangular parallelepiped, when it is lined up or piled up in preparation for flood damage, a considerable gap is created in the part where adjacent sandbags that are adjacent to each other or overlap each other, and water leaks from that part. It reduces the cutoff rate of water.

In addition, the sandbags are simply piled up or lined up at the time of use and are not connected to each other by a binding means such as a string, so that the resistance to water pressure of water is small and the piled state is easy. It has a drawback that the parallel state is collapsed and the function as a protective wall is easily lost. In that case, if adjacent sandbags are connected using a binding means such as a string, resistance to water pressure will increase and the function as a protective wall will be enhanced, but sandbags stacked or lined up in case of a typhoon or other emergencies will be strengthened. It is extremely complicated and time-consuming to connect them one by one with a binding means such as a string, which is not practical and practically impossible.

On the other hand, the Applicant has filled a water-permeable bag made of net or the like with an environmental purification material such as shells and placed it in the water or bottom of rivers, lakes, dams, ponds, etc. We have been purifying the environment from the past, but in that case as well, since the corners of the bag filled with shells are rounded and chamfered, there is a considerable gap between the parts where adjacent bags are in contact with each other. Occurs, and water passes through the portion without undergoing purification treatment, resulting in a problem of reduction in purification rate.

[0005]

Therefore, an object of the present invention is to provide a sandbag filled with a heavy material such as soil, or a bag filled with an environmental purification material such as a shell, when they are stacked or lined up. A simple and convenient method to reduce the gap between adjacent bags or overlapping bags as much as possible to prevent water leakage from that part, or even if you do not use binding means such as strings It is to provide a measure by which overlapping bags can be firmly fixed to each other.

[0006]

As a result of repeated studies by the present inventor, a bag filled with a heavy material such as soil or an environmental purification material such as a shell is flexible at least partially around the filled portion. The present invention has been completed by finding that the above object can be achieved by providing a fin-like piece that is water-impermeable.

[0007] That is, the present invention is a bag for filling with soil, sand or other heavy material, or shell or other environmental purification material, for filling the heavy material or environmental purification material. Is a flexible and water-impermeable fin-shaped piece provided at least at a part of the periphery of the filling part. Further, the present invention provides a filling portion filled with soil, sand or other heavy material, shell or other environmental purification material, and a flexible and water-blocking property provided at least at a part of the periphery of the filling portion. Is a bag filled with a heavy material or an environmental purification material.

As will be apparent from the above, the present invention includes both bags before being filled with soil, sand or other heavy items, shells or other environmental cleaning materials, and bags after being filled therewith. It is a thing.

In the present invention, when the bag is filled with soil, sand or other heavy material, a so-called sandbag which is widely used for prevention of water damage can be obtained, and the bag has shells and other environmental purification materials. When filled with water, a water quality purification material is formed which is used by being placed in the water or the water bottom of a water quality environment such as rivers, lakes, dams, and ponds.

When the bag of the present invention is used as a sandbag,
As a bag, heavy materials such as soil and sand made of conventionally known materials for sandbags such as natural fibers such as hemp and cotton, polypropylene fibers, polyester fibers, polyamide fibers, acrylic fibers, synthetic fibers such as vinylon do not leak out. A product manufactured from such a cloth can be used, and the material thereof is not particularly limited. Also, as the heavy object to be filled in the bag, a conventionally known heavy object can be used in the production of soil, sand, gravel, or other sandbags, and the kind thereof is not particularly limited.

The flexible and water-impermeable fin-like piece provided around the filled portion filled with heavy material is a material capable of blocking water to the same extent as or more than the filled portion of heavy material. It is better to form from. Therefore, even if the fin-shaped piece is made of the same material as the filling portion of the heavy object, it is made of the same material as the filling portion, and the portion is impregnated or covered with rubber or resin to prevent water impermeability. The property may be improved, or a fin-shaped piece made of a water-impermeable material different from that of the filling part may be formed in advance and bonded to the filling part. In order to easily and economically manufacture a bag having fin-shaped pieces, the fin-shaped pieces are made of the same material as the filling part, and the fin-shaped pieces are further coated with rubber or resin if necessary. It is preferable to apply water impermeable treatment such as. In that case,
Cut the dough larger than the usual sandbag bag by the amount of the fin, and in order to form a filling part for filling heavy objects, cut the dough at the part inside the fin by the amount of the fin rather than the end. When sewn, a bag for sandbags of the present invention, which has a filling portion in the center and a fin-shaped piece around it, is manufactured with almost the same work procedure and required time as in the case of producing a normal bag for sandbags. can do.

When the bag of the present invention is used as an environmental purification material, the bag is formed from natural fibers such as hemp and cotton, polypropylene fibers, polyester fibers, polyamide fibers, acrylic fibers, synthetic fibers such as vinylon, etc. A water-permeable mesh, a woven fabric or the like can be used, and the material thereof is not particularly limited. Also, the environmental purification material to be filled in the bag is not limited to shells, but charcoal, activated carbon, and solid materials having an alkali content-releasing ability [eg, slag, coal ash, cement latance, red clay, plaster, calcium carbonate, etc. A binder (for example, resins, gums, a small amount of cement, etc.) granularly solidified, or other conventionally known environmental purification material can be used, and the type thereof is not particularly limited. In particular, when using shells as an environmental purification material, various kinds of contents such as oysters, scallops, clams, clams, clams, blue goats, crow shells, turban shells, and mill shells, which have been conventionally difficult to handle, are separated. Shells can be used.

Further, as a flexible and water-impermeable fin-like piece provided around a filling portion filled with an environmental purification material such as a shell, an eye which is more water-impermeable than the filling portion is used. It is preferable to use a stuffed woven cloth, a woven cloth covered with rubber or resin, or a plastic sheet.

When providing a flexible, water-impermeable fin-shaped piece around the filling portion filled with a heavy object or an environmental purification material, it may be provided at least at a part of the periphery of the filling portion. This includes a case where it is provided only on one side of the filling portion, a case where it is provided on two sides, a case where it is provided on three sides, and a case where it is provided on the entire circumference. In that case, the fin-like pieces may be continuous without any notches, or may be provided with notches at one place or at two or more places. Furthermore, the fin-shaped pieces provided around the filling portion may be a single piece, a double piece, or more pieces. Further, the shape and size of the fin-shaped piece are not particularly limited, and can be appropriately selected according to the application of the bag, the use condition, etc. with reference to the specific examples described below with reference to the drawings. However, if the length of the fin-like pieces (the length in the direction hanging from the filling part and the length in the direction parallel to the periphery of the filling part) is too short, gaps will be created when sandbags or environmental purification bags are stacked or lined up. Care must be taken because the shielding effect becomes smaller and the reinforcing effect becomes smaller.

Further, the capacity (dimension) of the filling portion for filling a heavy material such as soil in the bag and an environmental purification material such as a shell is not particularly limited, and can be appropriately selected according to the purpose of use or the purpose of use. it can. Further, the shape of the filling portion may be an appropriate shape such as a square shape, a circular shape (disk shape), an elliptical shape (elliptical disk shape), and a cylindrical shape.

In order to facilitate understanding of the content of the present invention, a detailed description will be given below with reference to the drawings, but the present invention is not limited thereto. Taking sandbags as an example, Fig. 1
Fig. 1 shows a conventional sandbag, Fig. 1 (a) is a bag 1 for sandbags before being filled with heavy objects such as soil and sand, and Fig. 1 (b) is a heavy object such as soil and sand. The sandbag A after filling the bag 2 through the opening 2 of the bag and closing the opening 2 with the tie 3 such as a string. In FIG. 1C, the sandbag A is piled up on the shore of a river or the like in preparation for water damage. The state (a view parallel to the river flow) is shown. Then, as shown in FIG. 1 (c), in the conventional sandbag A, the corners thereof are chamfered and rounded, so that the space P is formed in the adjacent portion and the overlapping portion of the sandbag A.
Is formed, water leaks from the part, and the water blocking property is deteriorated.

On the other hand, FIG. 2 is a diagram showing an example of the sandbag of the present invention, and FIG. 2A shows a sandbag bag 1, (b) before being filled with a heavy object such as soil or sand. ) Represents the sandbag B after filling a heavy object such as soil or sand from the opening 2 of the bag and closing the opening 2 with the binding tool 3 such as a string. In the sandbag B of the present invention,
As shown in FIGS. 2 (a) and 2 (b), flexible and water-impermeable fin-shaped pieces 5 are continuously provided on three sides of the filling portion 4 filled with heavy objects. Therefore, when piled up on the shore of a river, for example, as shown in (c) of FIG. 2 (a view seen from the direction crossing the river), the fin-shaped pieces 5 are adjacent to the upper or lower side, When the sandbag B on the right side or the left side is bent and sandwiched by using the weight and pressure of the filling portion 4 [in Fig. 2 (c), the length of the fin-like piece at the bottom of the filling portion 4 is increased. Then, every other sandbag B is sandwiched between them.] The fin-like piece 5 closes the void P generated in (c) of FIG. 1 described above to reduce water leakage from that portion. It is possible to improve the function as a protective wall.

Further, at this time, the sandbags B arranged and piled up on each other are firmly sandwiched and fixed in the fin-shaped pieces 5 by the weight and pressure of the adjacent sandbags B, so that, for example, they are piled up. Even when a high water pressure is applied to a specific part of the sandbag, the sandbag in that part does not easily collapse and is fixedly supported by another adjacent sandbag, and the strength of the entire protective wall increases.

FIG. 2 shows a sandbag in which fin-shaped pieces are provided on three sides of the filling portion. However, the fin-shaped pieces do not necessarily have to be provided on the three sides. It suffices to provide it on at least a part of the periphery of the portion. For example, in the case of a rectangular bag, even if it is provided only on the bottom portion as shown in FIG. 3 (a), it is shown in FIG. 3 (b). As shown in FIG. 3 (c), or only on one side as shown in FIG. 3 (c), or as shown in FIG. 3 (d) at the bottom portion and one side. It may be provided only in. In the bag shown in FIGS. 3B and 3D, the width and / or length of the two fin-shaped pieces provided on both sides or one side and the bottom are the same as each other. Or different, and in some cases the shape may be different.

2 and 3, the opening of the bag is closed by a binding means such as a string. However, as shown in FIG. 4, the bag is filled with a heavy object such as soil. When the opening is later closed by sewing or the like, it is possible to obtain a sandbag in which the fin-shaped piece is formed on the entire circumference of the filling portion, which has the fin-shaped piece in the portion having the opening. Further, as described above, the shape of the filling portion is not limited to the square shape, and the fin-like piece 5 may be provided on the filling portion, for example, as a columnar shape as shown in FIG. 5 or other shapes. Further, the fin-shaped piece is not necessarily rectangular, and may have another shape as shown in FIG. 6, for example. Also, fin-shaped pieces 5
For example, as shown in FIG.
May be provided at an appropriate position to facilitate bending of the fin-shaped piece 5.

Generally, providing fin-like pieces on three or more sides of the filling portion for filling heavy objects can reduce the gap between the sandbags when the sandbags are stacked or lined up.
Moreover, the sandbags adjacent to each other can be more firmly fixed by sandwiching the fin-like pieces, which is preferable.

In forming the protective wall by stacking or arranging the sandbags of the present invention having fin-shaped pieces on the shore of a river or the like, the stacking and arranging methods are not particularly limited, and are suitable for each situation. The method can be adopted, and the method of handling the fin-shaped pieces (bending, placement, etc.) at that time is not limited to the method of (c) of FIG. 2 described above. It can be appropriately selected depending on the size (length), shape, position of the fin-shaped piece with respect to the filling portion, and the like. For example, in the sandbag B in which the fin-shaped piece 5 having the notch 6 as shown in FIG.
Place the fin-like piece on the bottom of the
The fin-like piece of the upper part (filling mouth) of the filling part 4 is sandwiched between the sandbags stacked on top, and the fin-shaped piece of one side of the filling part 4 is sandwiched between the sandbag below and the other side. The fins on the sides may be sandwiched between the sandbags stacked on top, or another method may be employed.

On the other hand, when an environmental purifying material such as a shell is filled, the shape of the filling portion, the capacity, the method of providing the fin-like piece, the size, the shape, etc. are set in each situation as in the sandbag described above. It can be selected as appropriate. When the environmental purification material-filled bag of the present invention having fin-shaped pieces is used, the water passing through the gap between the stacked or arranged bags is impermeable to the fin-shaped pieces. Since it is blocked by and passes through the filling portion filled with the environmental purification material, the purification efficiency of water can be further improved.

[0024]

When the bag (sandbag) of the present invention filled with a heavy material such as soil or the bag of the present invention filled with an environmental purification material such as a shell is used, those bags are stacked or lined up. When used as a bag, it is possible to reduce or eliminate a gap between adjacent bags or overlapping bags, and as a result, it is possible to reduce or prevent water leakage from the gap.
The function as a waterproof wall can be further enhanced, or the function as an environmental purification material can be further enhanced.

When the bag (sandbag) of the present invention filled with a heavy material such as soil or the bag of the present invention filled with an environmental purifying material such as a shell is used, adjacent or stacked bags are arranged. Since the fin-shaped pieces are sandwiched by the weight and pressure between them, the fins are firmly fixed and held to each other, so that the stacking or arranging structure can be kept stronger compared to the conventional one, and water pressure etc. Can have a higher protective effect. Moreover, the bag (sandbag) of the present invention filled with a heavy material such as soil or the bag of the present invention filled with an environmental purifying material such as a shell does not require a binding means such as a string to be provided, By simply stacking or arranging them in consideration of the arrangement method, the above-mentioned strong barrier action can be exhibited, and it is extremely simple and easy to handle.
