What are the main flood prevention and emergency water blocking parts suitable for Water-Absorbent Expansion Bag

       The Water-Absorbent Expansion Bag belongs to the temporary water blocking and anti-seepage equipment for flood prevention and emergency. It relies on the characteristics of rapid expansion and molding of polymer water absorbing resin when encountering water, and has the advantages of quick deployment and no need to fill sand and gravel in advance. It is suitable for temporary water blocking, interception, anti-seepage and sealing in various emergencies such as rivers, lakes, reservoirs, embankments, urban and rural waterlogging, underground spaces, factory stations, etc. The main application parts are as follows:

       1. Urban underground space entrances and exits: entrances and exits of underground parking garages, underground shopping malls, subway entrances and exits, civil defense passages, and underground pipe gallery entrances and exits, used to temporarily block rainwater backflow and set up temporary water retaining cofferdams.

       2. Location for handling dangerous situations in embankments and river channels: Temporary sub embankments constructed to prevent overflow at the top of river embankments, embankments, lake embankments, and seawalls; Dike body seepage and local anti-seepage and pressure seepage on the water side; Temporary protection for small scouring areas at the foot of embankments and bank slopes; Temporary interception and blockage of river tributaries and ditches.

       3. Urban and rural low-lying areas: Low rise residential areas, old residential areas, low-lying road sections, culverts, and water accumulation points under overpasses, used to intercept incoming water, partition drainage, and control the spread of water accumulation.

       4. Protective parts of industrial and mining enterprises and important stations: At the entrance of key facilities such as substations, distribution rooms, water pump rooms, data rooms, material warehouses, hazardous chemical warehouses, water plant pump stations, etc., temporary water blocking lines should be constructed to prevent equipment damage caused by water ingress.

       5. Gate valves, pipelines, and hazardous areas in well chambers: drainage inspection wells, valve wells, cable wells, and water supply and drainage pipeline damage overflow points, used for wellhead containment and local interception of overflow; Temporary sealing and pressure seepage of water leakage around the embankment pipeline.

       6. Cofferdam and Temporary Diversion Engineering: Temporary cofferdams and partial plugging for small channels, fish ponds, reservoirs, and landscape water bodies; Temporary water blocking enclosure during sudden water influx in construction foundation pit.

       7. Other emergency rescue scenarios: Partial water blocking for secondary overflow risks caused by flash floods and mudslides; Water blocking and protective road on one side of the emergency road and material transfer channel; Emergency defense measures should be implemented in advance at flood prevention material pre positioning points.
