Abstract
A barrier forming a temporary dam that may be erected quickly alongside a river in spate to protect a flood-prone area. The barrier (11) mainly consists of extractable piles (15) fitted in holes in the ground, and removable water-tight members (20) that may be mounted between the piles once they have been drawn out of the respective holes. The water-tight members may be made of a stack of metal beams and thick bars.
Claims11
A barrier system extending along a longitudinal direction along an edge of a flood-prone region for the prevention of floods, comprising:
- a plurality of erectable pillars, each pillar having a lower portion;
- a plurality of holes provided in the ground at the edge of the flood-prone region;
- each pillar adapted to be installed in one of the holes;
- each hole being constituted by a substantially cylindrical vat having an internal wall, the lower portion of the corresponding pillar forming a piston fitted to the internal wall of said vat;
- means for injecting a fluid under pressure into said vat such that an assembly of said vat and said piston constitute a lifting jack for raising the corresponding erectable pillar;
- and
- a plurality of sealed members mounted and maintained between said pillars.
