In which scenarios are Water-Absorbent Expansion Bag suitable for use

       The Water-Absorbent Expansion Bag belongs to a new type of emergency flood prevention material. The bag is filled with high molecular weight water absorbing resin, which quickly absorbs water and expands within a few minutes after contact with water. It transforms from a lightweight dry bag to a compact waterproof bag, without the need to fill it with sand in advance. It is easy to transport and deploy quickly. Compared with traditional sand sandbags, it eliminates the heavy process of loading and transporting sand, and is widely used in flood control and rescue, building waterproofing, pipeline emergency and other scenarios.

1、 Flood prevention, flood control and emergency rescue scenes

      1. Temporary sealing of riverbanks and embankments: When there is a risk of piping, seepage, or seepage in the embankment, quickly stack water absorbing expansion bags to construct a water retaining embankment, seal the seepage channel, and prevent the danger from expanding.

      2. Urban waterlogging water retaining: the entrances and exits of underground garages, subways, underground shopping malls, and power distribution rooms are quickly arranged before the arrival of rainstorm in flood season to prevent rainwater from flowing back.

      3. Emergency sealing of reservoirs and culverts: Temporary water blocking around small reservoirs and gates, and short-term construction of simple flood control cofferdams.

      4. Flood prevention at the entrance of residential areas, factories, and warehouses: Quickly build water barriers at the entrance of residential areas, factories, and warehouses to prevent rainwater from flowing into the interior.

2、 Emergency scenarios for waterproofing in construction projects

      1. Temporary sealing of foundation pit seepage: In case of seepage or water inflow in the foundation pit of a construction site, expansion bags should be used to enclose and control the seepage, and to protect the stability of the foundation pit slope.

      2. Emergency repair of basement seepage: sudden seepage of basement walls and floors, temporary water blocking and drainage, creating a dry working environment for maintenance and construction.

      3. Pipeline construction cofferdam: For water supply and drainage, sewage pipeline repair operations, temporary water enclosure, and isolation of accumulated water in the work area.

3、 Emergency repair of municipal and pipeline networks

      1. Water and sewage pipeline burst: The pipeline network suddenly bursts, and expansion bags are quickly stacked to block the accumulated water, reduce the scope of flooding, and protect surrounding equipment and road surfaces.

      2. Waterproof of cable trenches and communication wells: When water enters cable wells and communication inspection wells, stacked expansion bags block the water flow from continuing to enter, protecting power and communication equipment from being soaked in water and avoiding short circuit faults.

4、 Protection of factory buildings, warehouses, and computer rooms

      1. Material Warehouse Water Barrier: Water barriers are installed at the entrances of raw material warehouses and finished product warehouses to prevent flooding and rainwater from soaking goods.

      2. Waterproof of distribution room and server room: Power cabinets and data rooms are key waterproof areas. During the flood season, expansion bags are used as the first line of defense to prevent equipment damage caused by water ingress.

5、 Other emergency scenarios

      1. Emergency flood prevention for tunnels and pipe galleries: Comprehensive pipe galleries and emergency water blocking at tunnel entrances and exits.

      2. Family emergency reserve: low rise residential buildings and residents on the first floor are used as simple flood control materials to deal with short-term rainstorm water accumulation.
