FR2844284A1 - Movable, inflatable dyke for preventing flooding in military or civil applications, includes flexible or semi-rigid structure that can be filled with water to establish a fixed anti-flood mass that utilizes weight of water - Google Patents

Abstract

The dyke includes a flexible or semi-rigid structure that can be filled with water to establish a fixed anti-flood mass, utilizing the weight of the water itself. The dyke includes two or more pockets that can be separately or simultaneously filled using pumps, with the first filled pocket acting as a stabilizer and a primary anchorage. An Independent claim is included for utilization of the above movable dyke.

Description

  Mobile inflatable water installation, anti-flooding, mobile dike.

  The invention is in the field of civil or military engineering of inflatable and foldable water installations and tires For the moment the only solution against floods is the stacking of tens of thousands of sandbags or the construction of dikes with random texture and quality. The main characterization of the invention is the principle of filling a structure of flexible or semi-rigid material with water to establish a fixed anti-flooding mass.

  using the weight of water and mobile water storage facility.

  The invention is characterized by the fact of using a giant envelope from a few meters long to a few hundred meters or even kilometers, flexible which is filled with water, and which by its shape acquires such adhesion to the ground that it constitutes a dyke which can very easily be used in all kinds of circumstances. This giant pocket is characterized by the fact that it can be cleaned and then folded

  1 5 in the container from which it came out.

  The invention is also characterized by the fact that it can consist of two or more bags which can be filled simultaneously or not, the first filled bag acting as a stabilizer and the primordial anchoring element. An example

characterized on plate no.

  The invention is also characterized in that it contains internal elements which are tensioners in order to guide the inflation of the pockets and in particular of the pocket

  main and give its final shape to the swollen tube.

  The invention is also characterized by the possibility of inflating the second bag with air for the case where it is desired to establish a rapid barrier around a site to be protected against an escaped wild animal or around a site to be protected. The invention is also characterized by the fact that it can be used against a major risk such as the consequences of an earthquake on a dam, by limiting the risks

  flooding by installing these dikes across the riverbed.

  The invention is also characterized by the fact that it will be constructed with flexible materials which can be combined with rigid materials, for its construction, the principles of the construction of car tires will greatly assist in the

realization of the invention.

  The invention is also characterized by the use of drawings of adhesion to the ground (Figure no. 12) 3 5 The invention is characterized by the fact that it will contain airlocks allowing humans or robots to enter the inside of the canvas inflated to air, to clean it (Figure 13) The invention can also be characterized by the affixing or the integration of modest masses to better seal the edge of the flap of attack invention is characterized by the fact that several mobile dikes can be installed against each other in perfect juxtaposition, and thereby reinforce the mass and grip effect against a water wave or a tidal wave ( figure n014) The invention is characterized by the possibility of superimposing a movable dike on two others already installed on the ground to increase the working height (figure 15) Presentation of the figures and drawings

  Figure 14: Juxtaposition of mobile dikes Figure 15: Superposition Figures 16 and -17-extension and angles for mobile dike - fig.16: the minimum juxtaposition length must be three to five times the width of the mobile dike

  Fig. 17: a crossing pocket comes to nest in a hole in the previous dike.

  We inflate it first, the other structures come to overlap with the inflation around.

  Operation: (fig. 1 to 7 and 15 to 17) the mobile dyke will be deposited by the appropriate means of transport at the place where it is to be used, 4x4 truck, helicopter or other and 35 we will inflate water by means of pumps both pockets simultaneously., Like the grip pocket is much less bulky it will be quickly filled and by its dynamics, it will place all the elements of the dam in good place, the other large mass pocket will then be finished filling, and we can then complete the

  juxtaposed dike, then the superimposed dike if necessary.

  When the water arrives it passes over the foreground, crosses the ballast and begins to

  lean on the structure all the more as the water rises.

  This makes it possible to transform the rise in water into an ally to retain it.

  The pumping required to fill it contributes to lowering the price level

  neighbors waiting for the flood wave.

  For dismantling, wait for the end of the flood and empty the water from the tubes in

  accelerating their emptying by air pressure.

  If the filling water was loaded (dirty), workers or a robot could enter the mobile dyke to clean it under pressure and with pumps. Their removal is done in the same way as their placement. The invention can be used against a major risk such as the consequences of an earthquake on a dam, by limiting the risks of flooding by installing these dikes across the river bed.

  In addition, these installations make it possible to store water in large quantities in places where water is scarce while constituting hilly reservoirs which are very useful in many third world countries in semi-arid or Mediterranean climate. It is obvious that this invention is intended for industrial construction to prevent or assist in the context of public security in the event of natural disasters including: floods and fires etc. Page 4
