Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing an artificial structure for soil conservation and filling a soil in a double-twisted metal net to grow a plant for soil conservation. The present invention relates to a mattress type sandbag lining structure.

[0002]

BACKGROUND OF THE INVENTION The use of barriers and other protective structures to prevent soil erosion caused by overflow or precipitation is well known. This structure is constructed using so-called mattress type sandbags, for example in the form of a rectangular container filled with gravel, crushed stone and other materials and fitted with a cover,
It consists of a double-knitted wire mesh panel galvanized or galvanized and resin coated, and this panel is joined using wire ties or wire stitches. This structure is corrosion resistant and mechanically resistant. As a method of assembling the above-mentioned structure, one well-known method has a function like an actual << mattress >>, and covers land of essentially different form over a wide area without a gap. It is to build and use a large and thin mattress sandbag. In the manufacturing factory, wire mesh is processed as a preparatory work, and the mattress is divided into small chamber groups by vertical partitions formed from the mesh of the bottom sheet.

Further, there is also known a method of directly constructing a plurality of lateral partitions known as a << rib >> structure, in which the bottom sheet is folded laterally to form a << mattress >>.
A horizontal fold is formed at the same height as, and the same fold is formed on the side wall on the long side and the end wall on the short side.

Wire stitches are used to connect the cover sheet, the side wall and the end wall, and the side surface of each rib obtained by bending the bottom sheet. Some of these stitches are attached during factory fabrication and some are attached at the time of assembly.

When the container container is filled with soil and used as a ballast, there are problems of retaining earth in the structure, and problems of preventing leaching and dispersion of earth. Attempts have been made to overcome the above problems by spreading a sheet of soil fibrous material under and around the sandbag, but the results have been disappointing.

SUMMARY OF THE INVENTION An object of the present invention is to fill a mattress sandbag with soil, and then hold the soil in each of the small chambers in the mattress to construct a protective wall for growing a kind of plant, and to embank it. To protect or compact.

When forming a layer having a thickness of about 15 to 30 cm, which is reinforced (by the metal mesh of the mattress) and has a protective ability and stability, the plant growth in the mattress sandbags is accelerated, resulting in an embankment and a steep slope. It is possible to obtain the unique effect of achieving the nature conservation effect of soil. The soil fiber material must cover the bottom surface, wall surfaces, end surfaces and partitions over the entire length of the inner holding surface of the mattress body and completely cover the interior of the compartment of the mattress. When the mattress before filling is installed on the ground, the soil synthetic covering material is fixed manually or automatically by wire stitching to the inner frame of the double-stranded metal mesh made of zinc plating or zinc plating and resin coating that forms the mattress sandbag. To do.

Wire stitch materials have the same properties as mattress wire mesh. After placing the mattress with soil, to prevent the soil from leaching before the plant grows,
A constituent or layer is needed to hold the fine-grained material. Soil composite materials were designed to meet this purpose. It is used to cover the entire upper surface of the mattress and is secured to the upper edge and partition surface of the group of chambers using wire stitches. The soil composite is first placed under the cover of the double stranded metal net and clamped to the upper edge of the mattress using wire stitches to cover the top of the sandbag. The present invention employs two types of modifications for practical use. One of them is
Wire stitches are used on the soil fiber cover inside the lining to attach panels that are connected and fastened to each individual chamber inside the mattress, that is, to the hexagonal structure of the honeycomb, and the other is to install the components beforehand at the time of manufacturing. It is a method to attach a sheet (single panel) continuously by using wire stitch at one end. However, in this case, the bottom surface of the mattress sandbag and the inner surfaces of the lateral side << ribs >> (partition) and the end wall of the sandbag structure have a continuous structure.
Pay particular attention to the attachment prior to filling, without soil fiber material forming pockets that would impair the perfect function of the invention.
Make sure that it is installed and fixed to the wire mesh of the sandbag.

As outlined, according to the present invention,
By constructing a mattress sandbag with an internal plant protection barrier, the purpose of accumulating and retaining soil in each single compartment or mattress box is achieved, and the growth of plants inside the sandbag itself can be promoted.

The soil fiber material of the panel is usually a fiber construction of woven or non-woven material, obtained using techniques relating to thermoplastics such as polyethylene, formed as individual panels or continuous sheets, inside the wire mesh of sandbags. Is connected to the wire with a wire stitch. Other objects and advantages of the invention will be described below with reference to the accompanying drawings.

EXAMPLE The mattress sandbag construction in FIG. 1 (the left sidewall is not shown in the figure) was obtained by a standard factory assembly method.

A hexagonal double-stranded metal net of galvanized or galvanized and plastic coating, extending from the bottom sheet 1 and having end walls 2, side walls 3 and partitions 4, is a typical box-like structure. It is illustrated as a thing.

Stability of the structure is maintained by galvanized and plastic coated wire stitches 10 mounted between the ribs and between the ribs and the side walls, and also between the side walls and the end walls.

In the field, the structure is covered with a soil fiber panel 5, which is completely glued to the wire mesh and the panel group is fixed to the wire mesh with wire stitches 6.

When all the small chambers in the mattress have been completely filled with the soil 7, the mattress is first covered with the soil composite material 8 to hold the fine grained material, and finally covered with the wire mesh cover 9, When placed on site, the mattress sandbags are covered.

Similar wire stitches 10 are used to secure the ribs or partition surfaces to secure the soil composite material to the side wall of the sandbag and the cover sheet to the side wall.

In FIG. 2, the inner surface of the sandbag is coated with a continuous sheet 5'of soil fiber which is attached to one end of the mattress by wire stitching in advance during the manufacturing process. In the case of coating at the site, the sheet is adhered to the surface, and further folded, and the ribs of the partition 11 are coated to cover the entire mat without any exposed portion.

Wire stitch 6'of continuous soil fiber sheet
The fixing is continued by, and strongly adheres to the inner surface to eliminate the generation of voids.

In the embodiment according to FIG. 1, the filling of the soil 7, the coating of the soil composite material 8 and the cover 9 and the joining by means of wire stitching follow.

The present invention described in the schematic drawings and the embodiments is applied to all other kinds of variation in shape, size, material, etc., which belong to the scope of the invention, and deviates from the protection scope of the claims. It is also possible to replace the detailed technical specifications with similar specifications.
