Description

Flood control special bag

technical field

The utility model relates to a flood control equipment, more specifically, the utility model relates to a special bag for flood control.

Background technique

my country is a country with many lakes and rivers. Every year in summer and autumn, due to the continuous rain, the snow on the mountains melts, and the mountain torrents, many rivers converge, which often brings serious damage to the lives and property of the people along the banks of the river. Losses, especially the southern provinces and cities suffered the most. The woven sandbags used in flood fighting and rescue are single and dispersed, and they are easy to be washed away when building embankments to fight against floods; and ordinary woven bags often have problems such as open edges and tearing due to their low strength; It is smooth and brings a lot of inconvenience to the construction workers. In addition, these single-structure bags are usually more prone to loss than conventional flood control filling materials such as sand, soil, and yellow sand installed inside Shusong, and the handling strength is extremely high.

Utility model content

In order to solve the above-mentioned technical problems existing in the prior art, the purpose of the utility model is to provide a special bag for flood control. The woven bag of the utility model is light in weight and small in size, and is convenient for stacking, storage and transportation;

In order to solve the above-mentioned technical problems and realize the above-mentioned purpose, the technical scheme of the utility model is as follows:

A special bag for flood control, including an inner bag and an outer bag, wherein the outer bag is a flexible net bag, and the inner bag is a sealed plastic bag, and the plastic bag is filled with granular water-absorbing resin.

Wherein, the flexible mesh bag includes a mesh enclosure and a mesh bottom made of metal wires, a nylon rope is threaded along the edge at the top of the mesh enclosure, and the inner bag is arranged at the bottom of the flexible mesh bag .

Compared with the prior art, the utility model has the following beneficial effects:

The special bag for flood control of the present utility model utilizes the characteristic of superabsorbent resin that expands with water, and can be put into flood control and emergency rescue quickly when a flood occurs; and the woven bag of the present utility model is light in weight and small in size, and is convenient for stacking, storage and transportation; When in use, just put a small amount of stones into the flexible mesh bag and tie a rope into the water. Under the action of the stone's own weight, it can cling to the bottom of the dam or the edge of the embankment to prevent it from being washed away by water. The water absorption function is to control the water with water, and the weight of the water-absorbing bag rapidly expands to dozens of times after being immersed in water, so that it can be used for project closure in flood control, prevention of erosion, prevention of collapse, and wave protection.

Description of drawings

Fig. 1 is the structural representation of the special bag for flood control of the present utility model.

Detailed ways

As shown in Figure 1, the special flood control bag of the present utility model includes an inner bag 10 and an outer bag 20, wherein the outer bag 20 is a flexible mesh bag, and the flexible mesh bag includes a net made of wire Surround 22 and net bottom 24, have the nylon rope 26 that wears along the edge at the top of described net surround 22, and described inner bag 10 is arranged on the bottom of flexible mesh bag; Described inner bag 10 is the plastic bag of sealing , the plastic bag is equipped with granular water-absorbent resin 12, which can expand to dozens of times its original size in a few minutes after being exposed to water. Generally, the inner bag is filled with 1000-2000g of super-absorbent resin. The plastic inner bag described in the utility model has good airtightness, and will not absorb water and get damp during storage and transportation; when in use, just put a small amount of stones into the flexible mesh bag, tie a rope and throw it into the water, and the weight of the stone will Under the action, it can cling to the bottom of the dam or the edge of the embankment to prevent it from being washed away by water, and then use the water absorption effect of the super absorbent resin to control the water with water. It is used for closing projects in flood control, preventing erosion, preventing collapse, and blocking waves. The special flood control bag of the utility model can prevent the special flood control bag filled with granular water-absorbing resin from being washed away by flood or water flow by filling stones.

Although the specific embodiment has described the technical solution of the utility model in detail through the examples, those of ordinary skill in the art should understand that equivalent replacement or equivalent transformation forms can be adopted without departing from the disclosed scope of the utility model. implement. Therefore, the protection scope of the utility model is not limited to the above-mentioned embodiments, as long as there is no implementation that deviates from the essence of the utility model, it should be understood that it falls within the protection scope required by the utility model.
