Definitions

  • the invention relates tc a self closing flood barrier and a method for protecting a hinterland against floods by means of such a self closing flood barrier.
  • Self closing flood barriers are known in which a dam wall is forced upwards out of a chamber whenever the chamber fills up with water.
  • a flood barrier may be installed in for example a dike at a river side.
  • the flood barrier automatically rises in the event of a flood, thereby protecting the hinterland.
  • moveable flood barriers also referred to as moveable dams, offer the advantage that they constitute a dam only then when it is really necessary. In a normal situation, the dam is underground and invisible for the environment.
  • a moveable dam may comprise a vertical retaining wall which at its lowest side provided with a buoyant body housed in the chamber.
  • the buoyant body forces the retaining wall out of the chamber through an opening at the top of the chamber.
  • the buoyant body may also function as a blocking element in order to limit the upward movement of the retaining wall. In that case the buoyant body will be thicker than the upper opening of the chamber and is thereby prohibited to leave the chamber.
  • Publication EP 1950352 A2 discloses a flood barrier having a rectangular support block at one side of the chamber mounted to one of the chamber walls.
  • a buoyant body comprises a slightly inclined, nearly vertical, side surface which will result in the dam wall moving to the hinterland side of the flood barrier in case of flooding.
  • the buoyant body further comprises an extension at the bottom which abuts to the bottom of the rectangular support block in case of flooding. Due to the specific structure of the flood barrier, the retaining wall and the buoyant body will act as a lever wherein the water pressing against the water side of the retaining wall will try to tilt the floatable part.
  • the maximum pressure between the floatable part and the chamber occurs near the top of the chamber at the hinterland side, and between the support block and the buoyant body at the water side.
  • a contact surface is very small.
  • the flood barrier will be unstable in case of variable water pressure at the top of the retaining wall due to waves.
  • the contact surfaces are subject to wear due to high and variable pressures.
  • GB-A-2.369.387 discloses a movable flood barrier according to the preamble of claim 1.
  • the known movable flood barrier comprises a buoyant barrier member which is raised by allowing it to float on the flooding liquid.
  • the barrier member is located in a floatation chamber which is filled by the rising flood liquid when the liquid reached a predetermined danger level.
  • This barrier is a symmetrically constructed barrier in which the closure between the buoyant barrier member and the chamber is determined by the upward force of the flooding liquid on the buoyant barrier member.
  • the construction therefore requires a relatively large Buoyant member providing upward force with a large building depth below the surface as the floatation force has to be provided by a floating volume below the surface when the buoyant barrier member is in de raised, protecting position.
  • JP2000345537 discloses a barrier that raises upon flooding water based upon a fixation by means of a side guiding rail 22.
  • the upper fixation is only achieved by a point pressure on the sliding member 12 to stop an opposing stop 23 and having opposing point seals leaving a vulnerable construction that also provides substantially no resistance against forces imposed by the flooding water.
  • the dam wall member In case water enters the chamber, the dam wall member will rise so that eventually the inclined surface of the blocking element is forced against the inclined. surface of the support block. This will result in a sideward movement until the dam wall member abuts against the hinterland side wall of the chamber. In the closed state, the dam wall member has two contact surfaces, which results in reduced pressures as compared to the barrier of the state of the art. This will result in less wear and more stability of the total barrier.
  • the dam wall member By using only one support block, the dam wall member will be forced against the hinterland side wall resulting in an improved sealing of the dam wall member. Also the usage of only one support block is cheaper than having two support blocks. Furthermore, the usage of one support block will be favourable when having to maintain or repair the flood barrier.
  • the dam wall member comprises a substantially flat surface facing said hinterland side wall for abutment against said hinterland side wall.
  • the flat surface is favourable because it makes the closed barrier more stable.
  • the flood barrier comprises a sealing member arranged on said substantially flat surface near a lower outer end of said dam wall member to avoid said water from flowing between said dam wall member and said hinterland side wall.
  • a sealing member will improve sealing of the flood barrier and thereby preventing water from the water side flowing to the hinterland side through the flood barrier in case of a flood.
  • a reduced water pressure at the hinterland side of the wall member is realised and no tilting of the dam wall member occurs which would otherwise move away the dam wall member from the chamber wall at its lower portion.
  • the sealing member comprises rubber or the like.
  • the inclined surface of said support block and said inclined surface of said blocking element make, at least in use, an angle with the vertical, said angle having a value between 30°-60°, and preferably equal to about 45°.
  • the support block is removably arranged on said water side wall.
  • the support block may comprise a bottom which is connectable to said water side wall of said chamber by way of connecting means.
  • the support block may further comprise a lockable entrance which provides access to the connecting means.
  • a maintenance team can have access to the connecting means in a very simple and effective way.
  • the entrance can be opened after which one can disconnect the connecting means and can remove the support block.
  • the inclined surface of blocking element transfers to a less or non-inclined surface which is, at least in said closed state, distant from said water side wall of said chamber. In this way clamping of the dam wall member is minimized.
  • the blocking element, the forcing element and said retaining wall are one integrated part. This results in easy manufacturing and assembly.
  • the chamber of the self closing flood barrier may be arranged to be installed under the ground or partly under the ground, depending on the purpose.
  • the chamber is substantially arranged under the ground and connected through a water inlet/outlet with a service pit.
  • the flood barrier comprises a lid for closing an opening of said chamber, wherein said lid is fixed to an upper outer end off said dam wall member.
  • This lid may also function as an additional extension of the flood barrier in case of a flood because it will prevent waves from creeping over the outer top edge of the dam wall member.
  • the lid will function as a breakwater.
  • a second aspect of the invention relates to a method for protecting a hinterland against floods by means of a self closing flood barrier as described above, the method comprising:
  • Figure 1 shows an embodiment of a flood barrier according to the invention as applied in a dike 1.
  • Figure 1 shows the flood barrier in a resting state in which nearby water such as a river 10 has a normal water level.
  • the flood barrier comprises a chamber 3 having a water side wall 20 and a hinterland side wall 21.
  • the chamber 3 also comprises a bottom 22 which connects the two sidewalls 20, 21 respectively.
  • the walls 20, 21 may be constructed out of sheet steel or any other suitable construction known to the skilled person, such as concrete.
  • a retaining wall 4 is present which is supported at its lowest side by a buoyant body 5.
  • the retaining wall 4 comprises polyester. This material reinforcement may be filled with foam as a sandwich construction and is very strong and also very light.
  • the flood barrier also comprises a lid 6 fixed to the top of the retaining wall 4.
  • the retaining wall 4 together with the buoyant body 5 is also referred to as dam wall member.
  • the buoyant body 5 consists of two, preferably integrated, parts 5a, 5b and actually functions as both a forcing element for causing an upward movement of the dam wall member, and as a blocking element for limiting the upward movement.
  • the flood barrier comprises a support block 7 removably connected to the water side wall 20 by means of a connecting means 15.
  • the connecting means comprise bolts 15.
  • the support block 7 comprises an entrance 14 which is closed by way of a cover 23.
  • the position at which the support block 7 is mounted to the side wall 20 is adjustable. In this way, the opening of the chamber 3 can be adjusted to a desired dimension.
  • the flood barrier further comprises a service pit 9 which is connected to the chamber 3 by way of a water inlet/outlet 24.
  • the water inlet 24 is connected to a vertical pipe 12 in the service pit.
  • the water inlet/outlet 24 comprises a valve 13 that is opened in a case the chamber 3 is emptied. In that situation the water inlet/outlet functions as a water outlet 24.
  • the service pit 9 is connected through a channel 11 to the water side of the dike 1 as shown in figure 1 .
  • the flood barrier is practically invisible under normal water level conditions. On top, the lid 6 locks in the entrenchment space under normal conditions.
  • FIG 2 shows the self closing flood barrier of Figure 1 in a flood situation wherein a flood is present resulting in a high water level of the river 10.
  • the pipe and the water inlet 24 fill with water resulting in a water stream towards the chamber 3.
  • the water in chamber 3 will force the retaining wall 4 to move up because the retaining wall 4 together with the buoyant body 5 are floatable on water.
  • the dam wall member will move upwards until the buoyant body 5 is forced at its upper side against the angled wall 17 of the support block 7. This will not only limit the upward movement of the dam wall 4 but will also force the dam wall 4 against the hinterland side wall 21 of chamber 3.
  • a closing seal 8 will lock the barrier waterproof. Now the water can rise further without flooding the protected area, i.e. the hinterland.
  • the flood barrier functions completely automatically without the need for controlled water inlet.
  • the service pit 9 also acts as a kind of water filter. Dirt and mud coming from the river side will deposit at the bottom of the service pit and will not reach the chamber 3.
  • the sealing member 8 is arranged on or at the flat side of the dam wall member, and preferable at the lower end of the dam wall member.
  • Figure 2 it can be seen that the sealing member 8 seals off the space between the dam wall member and the hinterland side wall 21.
  • the pressure between the hinterland side wall 21 and the dam wall member 4,5 is far less than the pressure between the water side wall 20 and the dam wall member 4,5. This pressure difference will result in a force that prevents a lever mechanism as mentioned in EP 1950352 A2 .
  • the chamber 3 is drained through outlet 24 with one way check valves 13 or by means of a pump (not shown).
  • the dam wall member returns to its resting position within the chamber.
  • the lid 6 on top of the dam wall 4 then closes to prevent the inflow of waste or debris.
  • Figure 1 is shown that the dam wall member does not rest on a floor of the chamber 3. This results in a space in which mud and the like may deposit. Such deposition will effectively raise the floor of the chamber 3 but this raising will not affect the resting position of the dam wall member.
  • the lid will always close the opening of the chamber 3, even when dirt is present at the bottom of the chamber 3.
  • the lid will be presses downwards and will thus be closed due to the gravity forces.
  • the lid 6 is arranged to support traffic and may be part of a road surface, or a pavement.
  • Typical values for the height of the retaining wall 4 are 50 cm, 100 cm, 150 cm, 200 cm or 250 cm. However higher flood barriers are possible.
  • the flood barrier comprises one or more seals 26,27, see Figure 2 , for preventing dirt or waste like waif wood, from flowing into the chamber at the upper entrance when the water level is falling.
  • FIG. 3 schematically shows a cross section the chamber according to an embodiment.
  • the support block 7 is mounted at the inner side of the chamber wall 20.
  • the inclined surface 17 of the support block 7 has an angle ⁇ with the vertical, which is preferably between 30-60°, and more preferably about 45°.
  • Preferably the same angle ⁇ is used for the inclination of the surface 16 on the buoyant body 5.
  • FIG 4 shows an embodiment in which the flood barrier comprises two ground load plates 41,42 mounted on top of the side wall 20,21. These plates will reduce the pressure at the outside of the chamber walls so that the risk of the deformation of the chamber is decreased. Particular in situations wherein heavy traffic passes across the flood barrier, the plates 41,42 will be advantageous.
  • the invention may be practiced otherwise than as described.
  • the invention may also be used to provide a door for a garage or for closing/protecting any other entrance of a building. It may even be conceivable to provide water basins the walls of which are formed by the flood barrier described above.
