Description

Technical Field

[0001] The utility model relates to the technical field of flood control sandbags, in particular to a new type of emergency flood control sandbag for flood control projects. Background Technique

[0002] In recent years, extreme weather has occurred frequently, and the flood disasters brought by heavy rainfall in cities have caused non-negligible losses to people's lives and property. There are many underground buildings in modern cities, and backflow is extremely likely to occur during heavy rainfall, threatening lives and property. Usually, flood control equipment such as sandbags is set at the entrances of underground buildings.

[0003] Existing sandbags are heavy and large in volume, troublesome to carry and occupy space. And the water-absorbing and swelling sandbags on the market usually contain superabsorbent resin inside. When the superabsorbent resin is stored daily, it is in a dry state and its weight is light, and it is easy to be washed away by floods when directly placed at the water blocking port, which is not conducive to people's use. Therefore, the technical personnel in this field provide a new type of emergency flood control sandbag for flood control projects to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to provide a new type of emergency flood control sandbag for flood control projects to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A new type of emergency flood control sandbag for flood control projects includes multiple groups of inner bags arranged side by side, and an outer bag is sleeved outside each group of inner bags. Superabsorbent resin is filled between the outer bag and the inner bag. The tops of multiple groups of inner bags are connected to the same filling bag, and the center of the top of the filling bag is connected with a sealing port.

[0006] Preferably: Multiple groups of retaining pieces are sewn on the outer ring of the top end of the sealing port, and the same binding rope slides through the inside of multiple groups of retaining pieces.

[0007] Preferably: Long strip-shaped support strips are sewn in the middle of both sides of the filling bag, and carrying straps are sewn on both groups of support strips.

[0008] Preferably: A first connecting band is provided between two adjacent outer bags, and the bottoms of multiple groups of outer bags and the first connecting band are connected to the same second connecting band.

[0009] Preferably: The outer bag is made of canvas material, and the inner bag is made of polypropylene plastic.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. In this utility model, multiple groups of inner bags and outer bags are arranged in parallel. The inside of the inner bag is used to fill heavy sand, and a light and water-absorbing superabsorbent resin is filled between the inner bag and the outer bag. The overall quality of the new emergency flood control sandbag is relatively light and convenient to carry. Moreover, there is a weight in the center, which can facilitate the initial blocking of floods. The new emergency flood control sandbag is also conducive to improving the actual sealing performance between each other, thereby enhancing the flood blocking effect.

[0012] 2. In this utility model, a filling bag is provided to connect multiple groups of inner bags, and a sealing opening for connecting a retaining piece and a binding rope is provided on the filling bag, which can facilitate the rapid filling and sealing of the inner bag. Further, a support bar and a carrying handle are provided, which can facilitate the reverse pulling of the support bars on both sides to expand the sealing opening, and also facilitate the staff to lift and carry the emergency flood control sandbag. By setting a first connecting band and a second connecting band, the connection strength between multiple groups of outer bags can be improved, and it is also conducive to stacking and placing the emergency flood control sandbags.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1 to 2, in the embodiment of the present utility model, a new type of emergency flood control sandbag for flood control projects includes multiple groups of inner bags 1 arranged side by side, and an outer bag 2 is sleeved outside each group of inner bags 1. A superabsorbent resin 3 is filled between the outer bag 2 and the inner bag 1. The tops of multiple groups of inner bags 1 are connected to the same filling bag 4. The center of the top of the filling bag 4 is connected to a sealing port 5. When the emergency flood control sandbag is in use, water-blocking sand is filled into the filling bag 4 and the multiple groups of inner bags 1 from the sealing port 5. After filling, the sealing port 5 is sealed. In actual application of the emergency flood control sandbag, the multiple groups of arranged outer bags 2 and inner bags 1 can improve the stacking tightness of multiple groups of emergency flood control sandbags. And a superabsorbent resin 3 is filled between the inner bag 1 and the outer bag 2, which can reduce the handling mass of the sandbag and further improve the water-blocking and plugging effect.

[0018] In one embodiment, multiple groups of retaining pieces 6 are sewn on the outer ring of the top end of the sealing port 5, and the same binding rope 7 slidably penetrates through the inside of the multiple groups of retaining pieces 6. After the sand inside the emergency flood control sandbag is filled, the binding rope 7 inside the multiple groups of retaining pieces 6 is pulled. The binding rope 7 can be used to quickly seal the sandbag conveniently. Further, strip-shaped support strips 8 arranged in parallel are sewn in the middle of both sides of the filling bag 4, which can conveniently expand the sealing port 5 to fill sand into the multiple groups of inner bags 1. The support strips 8 are made of materials such as hard nylon rope belts or plastics with good toughness. Handling straps 9 are sewn on both of the two support strips 8, which can conveniently pull the two support strips 8 in the opposite direction to expand the sealing port 5, and is convenient for the staff to lift and carry the emergency flood control sandbag.

[0019] Among them, a first connecting band 10 is provided between two adjacent outer bags 2. The bottoms of the multiple groups of outer bags 2 and the first connecting band 10 are connected to the same second connecting band 11, which can improve the connection strength between the multiple groups of outer bags 2 and is convenient for stacking and placing the emergency flood control sandbags. The outer bag 2 is made of canvas material, and the inner bag 1 is made of polypropylene plastic, which is convenient for improving the wear resistance of the emergency flood control sandbag, etc., and can reduce the overall manufacturing cost of the emergency flood control sandbag.

[0020] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
