[Technical field to which the invention belongs]

 The present invention relates to a soil mass storage bag used for civil engineering work for storing earth mass, etc. for sandbags at river renovation and construction sites.

[0002]

[Problems to be solved by conventional techniques and devices]

 2. Description of the Related Art As a conventional earthen mass storage bag for civil engineering, for example, a bag formed of a synthetic resin sheet in a bag shape is provided. Generally, the bag for accommodating the earthen lump or the like is configured so that the mouth of a vinyl sheet serving as the bag body can be freely expanded and contracted, and the mouth can be closed after accommodating the earthen lump or the like. The inner volume of the bag body is 500 to 2000 liters.

[0003] The above-mentioned conventional storage bag for soil masses or the like accommodates earth masses, stones and other members in a bag body, and is used by being arranged at a predetermined position in a civil engineering work site such as a river construction. It is used to prevent intrusion of water, etc. However, the above-mentioned conventional lump storage bag is left outdoors during the construction period of 3 months or 6 months with the lump stored therein, so that the bag body is exposed to ultraviolet rays, dust, and other external factors for a long time. This causes the vinyl sheet to deteriorate. For this reason, when the above-mentioned once-used clay luggage storage bag is used for another construction, if the lump is again stored in the storage luggage, the vinyl sheet is damaged due to insufficient strength and cannot be used. There was a problem.

[0004] In order to address the above problem, a method of covering a storage bag containing a clump of earth with a separately prepared protective sheet has been adopted in some cases. However, using such a separately prepared protective sheet can prevent the storage bag from being deteriorated by ultraviolet rays or other factors, but after storing the earthen lumps and the like, the protective sheet is further placed on the above vinyl sheet. Since the protective sheet is transported to the construction site in a covered state, there is a drawback that the protective sheet is displaced or comes off.

[0005] In addition, when removing the luggage storage bag, it is necessary to remove the protection sheet covering the lump storage bag and then move the storage bag. The handling was troublesome, and the sheets had to be stored and stored separately, which was extremely inconvenient, and was a cause of high complaints from construction workers. Therefore, the purpose of the present invention is to provide an earthenware bag for civil engineering work that can effectively prevent ultraviolet ray deterioration of the earthenware bag used for civil engineering work and is easy to handle.

[0006]

[Means for Solving the Problems and Effects of the Invention]

 In order to achieve the above object, the earthen mass storage bag of the present invention is provided with a protective cover for covering at least the periphery of the bag for housing the earthen mass and the like, and the protective cover and the upper side of the bag are integrated. It is characterized in that the protective cover is formed so that almost the entirety of the protective cover can be folded on the upper side of the bag. In this configuration, the storage bag is placed on the top of the bag and then lowered from the top to cover the outer periphery of the bag. Can be easily covered.

[0007] For this reason, when the protective cover is applied after storing the clod, the protective cover can be easily applied to the correct position without worrying about a displacement or the like. Also, when winding up the protective cover, the storage bag can be easily exposed by lifting the protective cover upward from the lower side of the bag. At this time, the protective cover can be folded down and temporarily stored on the upper side of the bag, and work can be performed without considering the storage location of the removed protective cover as in the past. Can be.

Note that the state in which the protective cover can be folded on the upper side of the bag means a state in which the protective cover is rolled up, folded, stored in a bag, or tied with a cord-like member. According to a second aspect of the present invention, there is provided an earthenware luggage storage bag provided with a protective cover for covering at least a periphery of a bag for accommodating a lump or the like, and integrating the protective cover with the bottom side of the bag. And the protective cover is formed so as to be able to be folded almost at the bottom of the bag.

[0009] In the earthen lump storage bag for civil engineering work having this configuration, the protective cover is integrally provided on the bottom side of the bag body. Can be applied at the same time, and workability can be improved. Further, since the protective cover is provided so as to be foldable, the cover can be suitably stored without using the cover.

[Embodiment of the invention]

 Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a state in which the clod storage bag of the present invention stores a lump or the like, and FIG. 2 is a perspective view showing a state in which a protective cover is folded. The earthen luggage storage bag 1 for civil engineering is provided with a storage bag 10 for storing the earthen lump, and a protective cover 20 integrally provided at an opening of the storage bag 10. The storage bag body 10 is formed of a synthetic resin material such as polypropylene or polyethylene in a bag shape, and satisfies a size and strength capable of accommodating a block of 500 kg to 2000 kg in consideration of portability and the like. It is. The shape of the bag can be appropriately selected from a cylindrical shape, a dice shape, a barrel shape, and the like, and an opening portion 10a as an input port for soil chunks or the like is provided at an upper portion. Further, the storage bag body 10 is provided with a lifting belt 12 and has a length extending from the bottom of the bag body 10 to the upper side of the bag body 10 through the side surface 10b to store the earth mass and the like. It is configured to be able to be lifted in a state where it is set. The belt 12 can be lifted by using a forklift or the like in a state in which the earth mass or the like is accommodated, and FIG. 2 shows a suspended state.

The protective cover 20 is formed so as to cover at least the side surface 10 b of the storage bag 10, and if the storage bag 10 has a cylindrical cross section, the protection cover 20 is larger than the storage bag 10. The cover is easily formed by forming it as a cylindrical body having a size larger than one, and the protective bag 20 covers the storage bag 10 in a state where the earthen lumps and the like are stored, so that direct sunlight and the like on the storage bag 10 can be protected. Can be shut off. The material of the protective cover 20 may be formed of polypropylene, polyethylene, vinyl chloride, a composite material selected and laminated thereof, or a material such as rubber, cotton, hemp, or the like. Various materials can be used as long as they can cut harmful rays such as ultraviolet rays contained in sunlight and can withstand long-term outdoor use.

The protective cover 20 has one end of the cylindrical body sewn so as to be integral with the upper end of the side portion 10 b of the bag body 10. It can be folded from the end side and put together at the top of the bag body 10. As shown in FIG. 1, when the protective bag 20 is covered with the protective cover 20, the protective cover 20 is extended. By simply moving, the side surface 10b of the storage bag body 10 can be easily covered.

As shown in FIG. 1B, the protective cover 20 is formed at the lower end thereof with a string-like member passing through a peripheral edge of the end so as to be able to open and close in a so-called purse-like shape. After insertion, the protective cover 20 can be tied up so as not to peel off. The protective cover 20 is lowered from the mouth 20a so as to cover the side 10b of the bag 10 when in use, and is folded over the side 10b of the storage bag 10 when not in use. Can be done. The folded state refers to a state in which the protective cover 20 is rolled up, folded, housed in a bag, or tied up with a string-like member.

In the state before use, the earthen luggage storage bag 1 for civil engineering folds the protective cover 20 at the mouth side of the storage bag 10 to be integrated with the storage bag 10, and then folds the whole. By doing so, the storage bag 10 and the protective cover 20 can be stored integrally and compactly. Then, the mouth 10a of the storage bag 10 is opened to put the earthen lump or the like into the storage bag 10, and after the earthen lump or the like is thrown in, the mouth 10a is tied up with a string-shaped member. Then, the storage bag body 10 containing the earth mass or the like is lifted via the belt 12 and placed on a predetermined construction site or the like. Thereafter, the protective cover 20 is placed so as to cover the entire side surface 10 b of the storage bag body 10. While extending and covering, the lower part of the protective cover 20 is closed so that the protective cover 20 does not float due to wind or the like.

As a result, at least the entire side portion 10b of the storage bag 10 is covered by the protective cover 20, so that the sunlight is blocked, deterioration from ultraviolet rays is prevented, and dust and other external factors are also prevented. This can also prevent deterioration due to Therefore, the earthen luggage storage bag 1 for civil engineering can be prevented from deteriorating due to ultraviolet rays and other factors even if it is left outdoors for a long period of time. However, the use of the clay luggage storage bag 1 of the present invention makes it possible to use it repeatedly, which is effective in reducing costs by reusing it and reducing waste. We can provide eco-friendly products.

In the above embodiment, the opening 10a of the storage bag body 10 is not covered with the protective cover 20 because the opening is not applied to the inside of the bag 10 by the earth mass or the like, but the protective cover 20 is extended. Alternatively, the mouth 10a of the storage bag 10 may be covered. As another embodiment of the present invention, as shown in FIG. 3, the earthen luggage storage bag 2 for civil engineering has a protective cover 20 integrally attached to the bottom of the side surface 10b of the storage bag body 10.

In the storage bag 2, the storage bag 10 has the same configuration as that of the above-described embodiment, and the protective cover 20 is attached to an appropriate means such as sewing on the bottom side of the side surface 10 b of the storage bag 10. It is more integrated. The protective cover 20 is configured to be stored in a state where it is folded down at the lower side. The storage bag 2 can be lifted together with the storage bag 10 with the expansion of the bag 10 in response to the input of the earth mass or the like, so that the protection cover 20 can be easily covered. Can be done.
