Emergency dyke for flood protection comprises inflated tubes held down by layers of sheet material and weighted lines in sleeves

摘要

The dyke is made from a series of inflated tubes (1), each equipped with a layer of sheet material (2) to immobilise it and ensure a seal, with the end of the sheet material opposite the tube having a sleeve (3) containing a weighted line (4) such as a metal chain. The sleeve can be opened and closed by a sliding clasp fastener or Velcro (RTM) strips. In addition, a mesh layer (5) is extended between the sheet material and the top of the inflated tube to protect the latter from floating objects, and the main tube, which can be partially filled with water, contains an auxiliary tube (6) inside it in case it bursts.
