1. The water-absorbing material of the five-star water-absorbing expansion bag is a polymer chemical substance, which can rapidly expand 80 to 100 times after absorbing water.

2. A 420-gram water-absorbing expansion bag can swell to 18 to 20 kilograms after being immersed in water for 3 to 5 minutes.

3. After expansion, the water-absorbing expansion bag can withstand a pressure of 150 kilograms.

▁▄▆Water-Absorbing Expansion Bag---Application Areas:

1. Used for flood control, emergency rescue, plugging leaks and overflow protection of dikes, temporary heightening of flood control dikes, construction of temporary waterproof enclosures, seepage and landslide prevention for reservoirs and river embankments, slope protection against erosion, engineering flow interception, and blocking of underground ditches and tunnels;

2. Used for draining water from warehouses, courtyards, ditches, ponds, and flooded farmland.

3. Used in flood-prone factories, tunnels, underground parking lots, subways, and other areas as a measure to prevent water ingress.

4. Used for absorbing and removing water from積水 areas in road construction, bridge building at construction sites, competition venues, etc.

5. Used in mining, oil and gas field extraction, and other industrial enterprises that require rapid water removal, etc.

▁▄▆Water-Absorbing Expansion Bag----Features

① Before use, the expansion bag for flood control and emergency rescue is small in volume, lightweight, and easy to store and transport. Compared with traditional methods, it can greatly reduce manpower and save valuable time during emergencies.   

② The expansion bag for flood control and emergency rescue is an environmentally friendly product, being non-toxic, odorless, and pollution-free during use.   

③ After flood discharge, it does not cause sand and silt accumulation, eliminating the need for additional manpower and resources for cleanup. It can be reused, better protecting the environment and natural resources.    

▁▄▆Water-Absorbing Expansion Bag---Uses:

(1) Preventing embankment landslides: When an embankment is affected by seepage and begins to slide, timely intervention is crucial to prevent a collapse. Specific usage method: Stack water-absorbing expansion bags in multiple layers in a "pin" shape at the lower part of the sliding embankment to quickly halt further sliding, allowing time to fill and repair the collapsed slope.

(2) Raising embankments: Based on flood forecasts, if flood levels are expected to exceed design levels or even the embankment itself, use water-absorbing expansion bags to urgently build a small levee on the water-facing side of the embankment crest before the flood arrives to prevent overflow. Specific usage method: After the water-absorbing expansion bags have absorbed water and expanded, stack them in staggered layers and compact them tightly. To prevent interlayer leakage, add loose soil between layers. Using plastic film in conjunction can improve seepage prevention.

(3) Wave dissipation and erosion prevention: When floodwaters are rapid and water levels are rising continuously, they exert tremendous pressure on flood control embankments. Due to their flexibility, securely tied and stacked water-absorbing bags along the embankment can buffer the impact of floodwaters, achieving the goal of embankment protection and emergency rescue. Specific usage method: Lay the water-absorbing expansion bags flat, tie both ends to stakes on the embankment, and directly cast them onto the water surface. After expansion, the bags, having buoyancy, can rise and fall with the waves, effectively dissipating wave energy.

(4) Seepage pressure relief through water storage: Seepage is a common emergency in embankments. If the seepage point is small, timely blocking can prevent it from expanding. When the head difference between the water and land sides is small, use soil bags to urgently construct a larger cofferdam around the seepage point to store water and apply counter-pressure. Specific usage method: Using the land side of the embankment as a fixed edge, stack expanded water-absorbing expansion bags in multiple layers in a "pin" shape to form a sandbag wall, creating a rectangular water storage tank on the other side of the embankment. Then fill the tank with water to suppress seepage through hydraulic pressure. To prevent leakage, add a layer of plastic film on the inner side of the water-absorbing expansion bags.

▁▄▆Water-Absorbing Expansion Bag---Product Storage:

Store in a dry place within a warehouse, protected from moisture and dampness. Do not tear the packaging before use. The shelf life can reach 3 to 5 years. Keep it ready for use during normal times and deploy it anywhere during flood season for emergencies.
