Description

The present invention relates to a stuffing bag made of wire mesh.

Conventionally, packing bags made by filling stones inside are used to protect embankments and normal lines of roads. In addition, on the coastline, erosion due to the ebb and flow of tides and waves causes topographical deformation such as changes in the landscape of the coastline and reduction of sandy beaches. In order to suppress these, offshore breakwaters and breakwaters are constructed with packed bags to reduce the effects of the above-mentioned ebb and flow of tides and waves.

Conventionally, most stone-filled bags used for such purposes are made of chemical fibers (for example, Patent Document 1). This is because stone filling work can be done easily on site, and it is flexible and easy to follow the terrain when it is installed.

However, such chemical fibers deteriorate with the passage of time, and their scraps are washed away in rivers and seas. These scraps are called plastic pieces or microplastics and cause marine pollution. For example, the surface of plastic has fine irregularities, so it easily absorbs harmful chemical substances. As a result, toxic chemicals can build up in the bodies of marine animals that accidentally eat them, making them sick or dead. In addition, human consumption of these marine organisms may also affect the human body. In addition, chemical fiber bags have the disadvantage that they tend to deform when moved after being packed.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a stuffing bag that does not generate plastic fragments, microplastics, or the like.

In order to achieve the above object, the stuffing bag of the present invention is made of a wire mesh and includes a bag portion having an insertion portion into which a filling material can be inserted, a squeezing wire for tightening the insertion portion, and meshes of the wire mesh. and a reinforcing wire that is passed through the bag portion and formed around the side surface of the bag portion.

Moreover, it is preferable that the end portion of the insertion portion of the bag portion has a curled portion obtained by curling the upper end of the wire mesh for passing the squeezing wire.

Moreover, it is preferable that the reinforcing wire has a length of 95% or more and 105% or less of the maximum length around the bag portion.

Further, it is preferable that the reinforcing wire is arranged at a position where it can circulate around the filling material when the bag portion is filled with the filling material.

Moreover, the reinforcing wire may comprise a plurality of suspending wires for suspending the bag portion.

Further, the squeezing wire may be passed through the mesh of the curl portion or the end portion of the insertion portion of the bag portion.

Since the packing bag of the present invention is made of metal, even if it rusts and rots, it returns to the soil, thus preventing the problem of marine pollution such as microchips.

1 is a perspective view of a stuffing bag of the present invention; FIG. Fig. 3 is a perspective view of another pack according to the present invention; FIG. 3 is a perspective view showing a state in which the bag of the present invention is filled with stones;

A stuffed bag according to the present invention will be described with reference to FIG. The stuffed bag of the present invention, as shown in FIG. . Here, the filling material may be any material as long as it can be packed in a bag depending on the purpose of use.

The bag portion 1 is for holding a filling material such as a stone inserted from the insertion portion 11, and is formed in a bag shape by a wire mesh 12. As shown in FIG. As the bag part 1, for example, a sheet-like wire mesh 12 can be used that is joined together so as to form a round and cylindrical shape, the lower end of which is squeezed with a wire 5 or the like and fixed with a metal fitting or the like. . As the wire mesh 12, a conventionally known wire mesh such as a rhombic wire mesh or a tortoiseshell wire mesh can be used.

In addition, the mesh size of the wire mesh 12 is formed to a size that does not allow the inserted filling material to leak out. For example, when the filling material is a stone or a concrete mass, it is preferable to form it smaller than the stone or the concrete mass. Also, a large mesh size reduces the cost but reduces the strength, and a small mesh size increases the cost but increases the strength. Therefore, the size of the mesh may be appropriately determined depending on the purpose of use. Specifically, the size of one side of the wire mesh 12 can be determined within the range of 20 mm to 150 mm. Of course, the mesh size of the wire mesh 12 is not limited to this range.

Also, the wire used for the wire mesh 12 must have a thickness that is strong enough not to break when the stuffing material is stuffed into the bag portion 1 and lifted up. Specifically, the wire diameter of the wire mesh 12 can be appropriately determined within the range of 1.0 mm to 5.0 mm. Of course, the wire diameter is not limited to this range. Wires made of metal such as iron, stainless steel, aluminum, copper, or alloys thereof can be used. A wire rod coated with zinc plating or the like can also be used. Specifically, galvanized iron wire, stainless steel wire, aluminum alloy wire, zinc/aluminum alloy plated iron wire, aluminum-coated steel wire, copper wire, or the like may be used.

The insertion portion 11 is provided on the upper end side of the bag portion 1 and is an entrance for inserting a filling material or the like into the bag portion 1 . Any size may be used as long as the filling material can be inserted therein, but a wider one is preferable because it is easier to fill the filling material.

The squeezing wire 2 is for squeezing the insertion portion 11 . After filling the bag part 1 with the filling material and squeezing the insertion part 11, the insertion part 11 is fixed so as not to open. Any material may be used for the squeezing wire 2 as long as it can squeeze the insertion portion 11. For example, a metal such as iron or copper can be used. Also, it is possible to use a material other than metal as the drawing wire 2 as long as it is a material that does not turn into microplastics or the like and returns to nature. The length of the wire 2 for throttling should be longer than the circumference of the insertion portion 11 (the length of the upper end of the wire netting 12) and the size enough to close the insertion portion 11. The thickness of the squeezing wire 2 should be strong enough not to break when the insertion portion 11 is squeezed. As shown in FIG. 1, the squeezing wire 2 may be formed by bending the wire on the upper end side of the wire mesh 12 of the bag portion 1 into a curled portion 13 and passing through the curled portion 13, or as shown in FIG. It may be passed through the mesh at the end of the insertion portion 11 of the bag portion 1 .

In addition, the bag portion 1 is used to reinforce the wire mesh 12 when stuffing the inner stuffing material or when suspending the bag portion 1 filled with the filling material, or when suspending it with a suspending wire 4 described later. It is preferable to have a reinforcing wire 3 for dispersing the force applied to. The reinforcing wire is passed through the wire netting 12 and formed around the side surface of the bag portion 1 . Although not shown, it is also possible to prepare a plurality of reinforcing wires and arrange them at a plurality of locations.

The length of the reinforcing wire 3 is preferably 85% or more and 115% or less, preferably 90% or more and 110% or less, more preferably 95% or more of the maximum length around the bag portion 1. 105% or less is better. Any material may be used for the reinforcing wire as long as it has strength enough to reinforce the wire netting 12. For example, a metal similar to the wire material used for the wire netting 12 described above may be used. It is also possible to use a reinforcing wire other than metal as long as it is a material that does not turn into microplastics and returns to nature.

Further, the vertical position of the reinforcing wire 3 with respect to the bag portion 1 is preferably such that when the bag portion 1 is filled with the filling material, it can be horizontally circulated around the portion filled with the filling material. good. This is because the bag portion 1 is not squeezed by the reinforcing wire 3 when the bag portion 1 is suspended through the reinforcing wire 3 in the portion where the filling material is packed, and the wire mesh 12 is not squeezed. This is because the deformation of the can be suppressed. Specifically, assuming that the distance from the lower end to the upper end of the bag portion 1 that is not filled with the filling material is H, the reinforcing wire 3 is arranged between H/4 and H/2 from the lower end of the bag portion 1. Just do it. For example, the reinforcing wire 3 can be arranged at a position H/3 from the lower end of the bag portion 1 .

Further, as shown in FIG. 2, the reinforcing wire 3 is preferably provided with a plurality of, preferably three or more, suspending wires 4 for suspending the bag portion 1 . The lifting wire 4 is for lifting the stuffed bag after filling the stuffed bag with the filling material. The reason why the suspension wire 4 is attached to the reinforcing wire 3 is that if it is attached directly to the wire mesh, the wire mesh will be deformed. The suspending wires 4 are arranged at a plurality of locations on the reinforcing wire 3, and are preferably arranged at equal intervals in order to evenly distribute the force to the reinforcing wire. The material of the hanging wire 4 may be any material as long as it has the strength to support the weight of the stuffing material stuffed in the stuffing bag. You can use things. It is also possible to use a reinforcing wire other than metal as long as it is a material that does not turn into microplastics and returns to nature. Furthermore, when the suspension wire 4 is removed after the stuffed bag is installed in a predetermined place, it is also possible to use other reinforcing wires. The length of the suspension wire 4 may be of any length as long as it can be lifted by a crane or the like, and for example, a length of 3 m can be used.

Next, an example of the method for manufacturing the stuffed bag of the present invention will be described. First, the upper end and lower end of the wire mesh 12 manufactured to the necessary dimensions are rounded (curled) to form curled portions 13 . The wire mesh 12 is joined together at its sides so as to form a round and cylindrical shape. Also, the drawing wire 2 is passed through the curled portion 13 at the upper end, and the wire 5 is passed through the curled portion at the lower end. The squeezing wires 2 and the wires 5 may be passed through the meshes on the upper end side and the lower end side of the wire mesh 12, respectively. In this case, the above-described curling of the upper and lower ends is unnecessary. Next, the wire 5 at the lower end is squeezed to a size that prevents the filling material from spilling out, and the wire 5 is fixed with a metal fitting or the like so that the lower end does not open.

When the bag part 1 is stuffed with the filling material, the reinforcing wire 3 is passed through the mesh of the wire mesh 12 at a position where it can go around the part filled with the filling material so as to be substantially horizontal. Fix both ends of 3 with metal fittings. Also, after the reinforcing wire 3 is formed in the bag portion 1, a plurality of suspending wires 4 are fixed to the reinforcing wire 3 with metal fittings or the like. The suspension wires 4 are preferably fixed to the reinforcing wires 3 at equal intervals.

The metal packing bag thus formed can be constructed in the same manner as the conventional chemical fiber packing bag. In addition, compared with packing bags made of chemical fibers, there is no inferiority in terms of flexibility, cost, construction period, etc. In addition, if an aluminum-zinc alloy plated wire or the like is used as the wire material of the wire mesh 12 used in the packing bag, rust will not occur for a long time, and even if the shape of the wire material is finally lost, the stuffing material will remain in that position. No problem to settle in. In addition, even if the metal wire itself rusts and rots, it returns to the soil, so it does not cause marine pollution problems such as microchips.
