(57) [Summary] [PROBLEMS] To provide a sandbag capable of being stably stacked at a predetermined location such as a civil engineering construction site or a disaster area. SOLUTION: A sandbag which is packed in a bag at a predetermined place, such as a civil engineering construction site or a disaster area, and is piled up in a large number. A member 3 is provided.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sandbag for stacking a large number of pieces at a predetermined location at a construction site or a disaster area to prevent inflow of earth and sand or water into a non-working area at a low place.

[0002]

[Prior art]

 Sandbags are generally formed by sewing a woven fabric made of natural fibers such as hemp or synthetic fibers such as nylon or polypropylene into a bag shape. They were used in an inflated state, and were usually piled up at specified locations such as civil engineering construction sites and disaster areas to prevent water and sediment from flowing into non-work areas in low places.

[0003]

[Problems to be solved by the invention]

 However, in the conventional sandbags, the soil is packed in bags sewn with the above-mentioned fibers, and a large number of the sandbags are piled up as they are. Therefore, in use, the bags are joined only by contact between the fiber surfaces. There was a concern that the bonds between them were weak and piled up in an unstable state, and the sandbags piled up at predetermined locations collapsed and could not sufficiently play the role of preventing the inflow of water and sediment.

An object of the present invention is to provide a sandbag capable of being stably stacked at a predetermined location such as a civil engineering construction site or a disaster area.

[0005]

[Means for Solving the Problems]

 The present invention is directed to a sandbag that is packed in a bag at a predetermined location such as a civil engineering construction site or a disaster area, and is piled up in a large number. Is provided.

Here, the non-slip member is a material having a large frictional resistance that does not easily shift when the sandbags piled up at a predetermined location such as a civil engineering construction site or a disaster area come into contact with each other. It is sufficient if it is formed.Specifically, using a roll device or the like, the melted rubber is hung in a strip shape and fixed on one side of linen in a stitch shape, or a rubber The strip may be fixed to the entire sandbag. Examples of the material of the non-slip member include synthetic rubbers, natural rubbers, and silicon, and any material that has a large frictional resistance at the time of contact with another bag or the non-slip member is particularly limited. Not a thing.

With this configuration, for example, even when a large number of sandbags are piled up to the outflow-side height at a civil engineering construction site, a disaster area, etc., in addition to the slip member provided on each sandbag bag, Due to the contact with the sandbags, the frictional resistance of the contacting parts between the sandbags increases, and even if a large number of sandbags are stacked, the sandbags are not easily displaced, so that the formation of the sandbags becomes strong and the installation state is stabilized.

[0008]

[Embodiment of the invention]

 One embodiment of the sandbag of the present invention will be described in detail below. First, a general use state of the sandbag 1 will be described. In general, the sandbag 1 is provided in a non-working area in a lowland where water or sand is expected to flow out of a highland as shown in FIG. By stacking a large number of the sandbags 1 until the height is the same as the height of the place 13, the inflow of water and earth and sand into the non-working area in the lowland is prevented.

[0009] In the production of the sandbag 1, first, using a roll device (not shown), the dissolved liquid synthetic rubber is dripped in a belt shape on one side of one linen cloth. Furthermore, the belt-shaped synthetic rubber is sequentially welded to one side of the linen so as to form a stitch. As a result, a non-slip member 3 made of synthetic rubber is provided on a part of the linen cloth, and after the non-slip member 3 is cooled and solidified, the linen cloth 2 is sewn in a bag shape with one side opened. The bag 2 is folded outwardly along the periphery of the opening 5 of the bag 2 to provide the bag 9, and the string 8 is passed through the bag 9, thereby forming the sandbag 1 of the present invention.

When the sandbag 1 manufactured in the above procedure is used at a civil engineering construction site, the bag 2 is filled with about eight minutes of soil inside the bag 2, and the opening 5 is closed with a cord 8. Thus, the sandbag 1 is actually used at the civil engineering construction site.

Here, the non-slip member 3 may be formed by welding a linen cloth into a bag shape, and then forming the non-slip member 3 from the linen cloth in addition to welding synthetic rubber in a mesh shape as in the above embodiment. The formed bag body 2 may be formed by fixing a granular mass of rubber to the whole of the formed bag body 2. Even if formed in this way, the frictional resistance when the sandbag bags 1 come into contact with each other increases, thereby increasing the number of bags. Even when a number of sandbags 1 are stacked, the sandbags formed with stability are not easily collapsed.

[0012]

[Effect of the invention]

 According to the present invention, since the non-slip member is provided on the outer surface side of the sandbag, the sandbag formed by stacking the sandbags is stably installed by the interposition of the non-slip member provided on each sandbag. The upper and lower sandbags are connected to each other to prevent water and sediment from flowing into the low-level non-working area, ensuring that water and sediment do not flow down. Can be prevented.
