Before the arrival of the flood season, Wuhan has assembled floodwalls around its city dikes.
The columns and the horizontal barriers are made from aluminum alloy capable of withstanding prolonged immersion in water as well as intense pressure.
The floodwalls have the advantages of easy assembly and disassembly.
The floodwalls can be dissembled when the water level is low.
