DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a river bank flood barrier forming a temporary dam, adapted to be raised in a short time, for example along a river in spate, to protect a flood-prone area.
BACKGROUND OF THE INVENTION
In times of flood, it can be known several hours in advance whether a river will overflow its banks and flood inhabited regions. The invention permits putting this time to good use to construct a temporary dam hereinafter called a flood barrier, whose infrastructure is already pre-established between the river bed and the flood-prone region.
SUMMARY OF THE INVENTION
More particularly, the invention relates thus to a river bank flood barrier for the prevention of floods, comprising at least one hole (16, 60) provided in the ground at the edge of a flood-prone region, and at least withdrawable portions of a dam (15, 62) installed in such holes, characterized in that it comprises a plurality of erectable pillars (15), each pillar being installed in such a hole, and sealed barriers (20) mounted and held between said pillars.
According to one embodiment, there is provided a plurality of erectable pillars, installed in holes provided in the ground at the edge of the flood-prone region and sealed removable barriers adapted to be installed between said pillars when the latter are raised from their respective holes, above the ground level.
As mentioned above, the construction can be built along a river but also along the sea to protect the land or a road, during high seas.
In the construction described above, each pillar comprises for example a metallic portion of H cross section forming a holding structure for two said barriers. Each barrier can be itself constituted by a stack of metallic beams and thick laths of elastomeric material. Preferably, each metallic beam has an H shaped profile and, on opposite sides of the central core of this beam, are built in a lath comprising a longitudinal groove and a lath comprising a longitudinal rib, said rib and said groove interfitting respectively into a groove and rib of two other laths incorporated in adjacent metallic beams. The sealed barrier can thus also be provided with a stack of such elements between two pillars, constituted of metallic beams and laths of elastomer material. These elements can be stored nearby or brought by truck at the time of construction of the flood barrier.
As a modification, the barriers installed between the erectable pillars can be disposed in trenches provided between the respective holes of the pillars.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will be better understood and other advantages of the latter will become more apparent in the light of the description which follows, given solely by way of example and with reference to the accompanying drawings, in which:
FIG. 1 is a fragmentary perspective view of a flood barrier according to the invention, shown at the time of use;
FIG. 2 is an exploded detailed perspective view of the principal elements of an erectable pillar;
FIG. 3 is an exploded detailed perspective view of a constituent element of a sealed barrier adapted to be mounted between two erectable pillars;
FIG. 4 is a detailed perspective view showing such elements about to be assembled; and
FIG. 5 is a view similar to FIG. 1, showing a modification.
DETAILED DESCRIPTION OF THE INVENTION
The flood barrier 11 according to a possible embodiment of the invention, constitutes a linear barrier which can extend over several hundreds of meters, even several kilometers, along a river 12 on the bank 13, to protect a flood-prone region, typically an inhabited region, in case of the river being highly in spate. The function of this flood barrier is hence to raise artificially the level of the bank to avoid the river overflowing its banks.
To do this, a retractable infrastructure is installed permanently along the bank, which is to say more generally along the edge of the flood-prone region. This infrastructure comprises a plurality of erectable pillars 15, disposed at regular intervals, insta
