Application scope of water-absorbent expansion bags
(1) Preventing dam landslides When the embankment is affected by water seepage and causes a landslide, if it is not stopped in time, there is a risk of the embankment collapsing. The specific method of use is to use water-absorbent expansion bags and stack them in multiple layers in the lower part of the embankment to prevent the dam soil from continuing to slide in a short time. At the same time, it can speed up the time to fill the soil and repair the collapsed embankment.
(2) Raise the dam. According to the water condition forecast, the flood level will exceed the design flood level and may even exceed the dam. Before the flood comes, use absorbent expansion bags to repair the sub-bank on the water side of the top of the embankment to prevent overflow. . Specific usage method of absorbent expansion bag: After the absorbent bag is inflated, it is layered and compacted. In order to avoid leakage between layers, loose soil should be added between layers. If it can be used with plastic film, the anti-seepage effect will be better.
(3) Wave suppression and anti-scouring. When the flood is too rapid and the water level continues to rise, it will cause huge pressure on the flood control dam. Since the absorbent expansion bags have a certain degree of flexibility, the absorbent bags must be firmly stacked beside the embankment. It can buffer the impact of floods on the embankment, thereby serving the purpose of embankment rescue. The specific method of use is to spread the absorbent expansion bag flat, tie both ends of the bag to the embankment stakes with ropes, and throw it directly on the water. After the absorbent expansion bag is inflated, because the absorbent bag has a certain buoyancy, it can rise and fall with the waves. Play a role in eliminating waves.
(4) Piping water storage and back pressure Piping is a danger that often occurs in dams. When the piping mouth is small, seize the time to block it to prevent the area from expanding. When the water head difference between the front and back is small, earth bags can be used at the water inlet to repair a larger area of wells and store water for back pressure. The specific method of use is to use the backwater side of the dam as a fixed side, stack the expanded water-absorbent expansion bags in a multi-layered shape to form a sandbag wall, and surround a rectangular water tank on the other side of the dam, and then put it into the tank. Inject water to suppress pipe backflow through water pressure. To prevent leakage, a layer of plastic film should be added to the inside of the absorbent expansion bag.
The disadvantages of traditional sand and soil bags are that a large amount of sand, gravel and soil must be prepared before use, which cannot be stored in cities and plain areas with high river beds. It takes a lot of time and manpower to fill, and also requires a lot of manpower and material resources to transport. Solid waste needs to be cleaned up after use, which consumes a lot of manpower and material resources and pollutes the environment.
International Trends in Water-Absorbent Expansion Bags Water-absorbent expansion bags have long been widely used in flood-prone Europe, the United States, Japan, Taiwan and other places. Its actual efficacy has been widely recognized by governments at all levels and the public, confirming that this bag is a simple and efficient flood prevention product that can quickly block water. The appearance specifications of this product, each gross weight, after water absorption, water absorption time in minutes. (If customers require special specifications, they can be customized according to actual needs). The absorbent expansion bag products are stored in a dry place in the warehouse, moisture-proof and moisture-proof. It is strictly forbidden to tear the packaging before use. The storage period can be up to ~ years. It can be prepared but not used in normal times, and it can be used as an emergency anywhere during floods.
Three major advantages of the five-star flood control emergency water-absorbent expansion bag
, environmental protection
The water-absorbent expansion bag is filled with a new type of polymer nano-water-absorbing material, which is non-toxic, odorless, non-polluting, and absorbs water Before swelling, it is a very small particulate matter. After absorbing water, it becomes a water-containing material about the size of a black bean. It is clean and pollution-free. After the polymer water-absorbing material is used, it can be used for agricultural water conservation and drought resistance. Therefore, the material in the bag can be dumped on the spot after a flood. In farmland, it can be completely decomposed in the soil. It is the first choice product that is green and environmentally friendly and kills two birds with one stone. The outer bag is made of pure linen and cotton, and the hemp rope can become stronger and more wear-resistant when exposed to water.
Complying with international trends
This kind of water-absorbing and expanding sandbags have long been widely used in flood-prone Europe, the United States, Japan, Taiwan and other places, and its actual efficacy has long been widely recognized by governments at all levels and the public.
Easy to transport
A large amount of sand, gravel and soil need to be prepared before use, or it can be tied to a fixed location. It is recommended not to use it in cities and plain areas with high river beds. The process of use does not look like Ordinary flood control sandbags require a lot of time and manpower to fill and transport. After use, there is no need to spend a lot of manpower and material resources to deal with sand and soil, and it does not pollute the environment.
Precautions for water-absorbent expansion bags
Usage method 1. Take out the water-absorbent expansion bag from the plastic sealed bag. 2. Soak the absorbent expansion bag evenly in water. After a few minutes, the absorbent bag will fully expand and can be directly used to block water and heighten the dam. 3. If it is used to remove water and prevent leakage, you can directly place the absorbent bag where water accumulates. The absorbent bag will automatically absorb the accumulated water and prevent it from seeping in. 4. If it is used for cutting, the absorbent bag can be put into the leak. The absorbent expansion bag can seal the leak after absorbing water.
Disposal method 1. After use, it can be left in place to dry naturally and then disposed of as waste. 2. Bury the absorbent bag underground, and the bag will degrade naturally. Storage method: Since water-absorbent expansion bags are easy to absorb water and swell, unused expansion bags should be returned to the plastic bag for sealed storage and placed in a moisture-proof and dry place to avoid moisture affecting the effect.
Hebei Five Star [water-absorbent expansion bag
, it has the following significant featuresbr/> ⑴. Hebei Five Star/Flood Control/Expansion Bag has the following significant features
. Hebei Five Star/Flood Control/Expansion Bags can be ordered as required
. Hebei Five-Star Flood Control/Expansion Bag can quickly turn the floodwater into solid material in the bag when it encounters water. When the water is solidified, it expands and squeezes horizontally, effectively preventing leakage at the joint.
． Hebei Five Star/Flood Prevention/Expansion Bags use water to keep out water and meet emergency flood prevention needs.
． Hebei Five Star/Flood Control/Expansion Bag The expanded material in the bag is water, which does not require excavation and transportation of soil, sand and gravel, saving a lot of manpower, materials and transportation, which is beneficial to environmental protection and ecology, and its advantages are particularly highlighted in places where there is a lack of sand and gravel soil sources. .
, Hebei Five Star/Flood Control/Expansion Bag operates quickly, with high efficiency and speed. It can provide quick rescue in the critical moment of emergency flood control.
． Hebei Five Star/Flood Control/Expansion Bag Flood Control requires no equipment, no complicated technology, and is easy to operate.
Comparing Hebei Five Star/Flood Control/Expansion Bags with flood control bags filled with sediment, the investment in manpower and material resources is significantly reduced. One bag has multiple uses. It can block water, prevent seepage and prevent waves, and can effectively protect embankments.
