JP3093245U - Rapid swelling sandbag - Google Patents

Abstract

(57) [abstract] (with correction) [Problem] The outer bag has water absorption and is hard to corrode, and the water absorbing agent can be returned to the original state after the moisture is evaporated.
Provide a sandbag that can be stored compactly. SOLUTION: Polypropylene fibers resistant to corrosion are used, and natural pulp fibers are interwoven to maintain water absorbency, thereby forming sandbags having water absorbency and oil absorbency. The sandbag is filled with a water-absorbing polymer having a high swelling rate in order to quickly expand with water and prevent water from entering. [Effect] Using a sandbag that has both water absorption and oil absorption, the swelling rate is high, and the sandbag is completed in about 3 minutes. Therefore, it is adaptable to the prevention of flooding in basements and underground malls in the event of an emergency, and before swelling. Due to small volume and weight, high space efficiency,
Suitable for emergency such as convenience of transportation, transportation, storage, etc.
Equipment for disaster prevention.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention is mainly applied to flooding of rivers due to heavy rainfall, flooding due to collapse of dikes, etc. Rapid inundation of basements and critical equipment and facilities due to rapid inundation of It Prevent serious accidents related to human life and protect socially important facilities and equipment It is a device for earthworks for.

[0002]

[Prior art]

  Conventional sandbags are made of polypropylene or hemp sacks filled with earth and sand, and are heavily used. The outer bag, which has been used for a long time after use, cannot be reused due to corrosion, and the weight of the sandbag is reduced. It was too big and I had a hard time handling it. In addition, it is difficult to store, so make a sandbag each time a disaster occurs It was difficult to use, and after use, it was actually discarded or left behind. Much more For example, if you want to respond quickly in an emergency It was impossible. In addition, the sandbags after use can be reduced and stored compactly for reuse. It was impossible to do.

[0003]

[Problems to be solved by the device]

  Conventional sandbags are concentrated in heavy rain, and underpasses, basements, and grounds caused by rapid flooding The inundation of sewage iron, etc. could not be dealt with and the serious accident could not be prevented.

[0004]   In consideration of such problems, the present invention is a result of repeated devising to prevent a serious disaster in an emergency. , Is solved by the method described below. That is, the outer bag is water absorbent , Made of a material that does not easily corrode, and the water absorbing agent should be returned to its original state after the water has evaporated. It can be stored compactly and can be reused to prevent another serious accident. You can

[0005]

[Means for solving the problem]

  In order to achieve the above desired purpose, first, polypropylene Fibers are used, and natural pulp fibers are interwoven to maintain water absorption. Make sandbags with oiliness.

[0006]   In addition, the absorbent material is woven in a loop shape into the water absorbent and oil absorbent fiber material. It is even better to use a stretchable cloth.

[0007]   The water-absorbing polymer in the sandbag is a bag to prevent sudden water ingress. In order to prevent the infiltration of water by swollen quickly by water and swelling and the sandbags pile up without gaps Encloses a water-absorbing polymer having a high expansion rate in a bag.

[0008]   In addition, when water invades, the sand is also enclosed to prevent the sandbag from floating, so Prevent floating.

[0009]   In addition, the side of the bag can be opened and closed so that you can quickly change the absorbent and change the composition. I will To prevent the opening / closing part on the side of the bag from tearing due to expansion of the swelling material inside, Seal with a chuck.

[0010]   After use, dry the sandbags containing water without exposing them to rain or water and let them dry thoroughly. When the product is reduced, fold it up and store it for repeated use. In addition, the composition of the water absorbing agent If you need to change it, just remove the magic chuck on the side and replace it.

[0011]

[Embodiment of device]

  An embodiment of the present invention will be described with reference to the drawings. A in the figure relates to the present invention This is a sandbag, and this sandbag A has an exterior formed in a predetermined size as shown in FIG. A bag 1 and a water absorbing agent (contents) 2 enclosed in the outer bag 1 are provided.

[0012]   In addition, in order to remove, replace, readjust, change composition, etc. Is equipped with. The inlet / outlet is a magic chuck that does not easily tear. .

[0013]   The outer bag is sewn from oil-absorbing and water-absorbing materials. The oil and water absorbing material is polypro Oil-absorbent synthetic fibers such as pyrene and natural pulp fibers, cotton yarn, rayon, soft cloth, jute It is recommended to use an elastic cloth knitted with water absorbing fibers such as.

[0014]   It is preferable that the water absorbent body 2 absorbs water to form a gel polymer and has a high swelling rate. The threshold is preferred. The water-absorbent polymer may vary slightly depending on the water quality, water temperature, etc. used. However, about 500 g of water absorber absorbs 22 liters of water. Exactly 3 minutes Sandbags will be completed.

[0015]

[Effect of device]

  The present invention is quick adaptability, high space efficiency, convenience of transportation, transportation, storage, etc., Reusable economy, resource saving, ecology, eco-friendly, just in case of emergency It is a disaster prevention equipment that is suitable for use. Also, transportation, installation, construction, storage, replacement, etc. It is very convenient, convenient and reduces labor, cost and expenses.   Therefore, the practical value of implementing the present invention is enormous.
