Definitions
- Embankment device Description According to a first aspect, the present invention relates to an embankment device, in particular an artificial, height-adjustable embankment device.
- Embankment devices of the artificial, height-adjustable type are known in several variants and serve to repel water threatening to flow in an undesirable direction or into an undesirable area.
- Fixed embankments exist, such as dikes and quay walls. This type of embankment is present in a permanently visible manner.
- the present invention relates to embankments that are height-adjustable depending on circumstances. That is to say, temporary embankments that can be activated when desired and (semi)permanent embankments that can be elevated in situations with relatively high water levels.
- Known height-adjustable embankment devices comprise floats floating on a water surface, at least when the water to be repelled is at the level of the respective float, stackable sandbags or undeformable, block-shaped, stackable modules, posts erected at regularly-spaced intervals of several meters, between which baffles can be pulled-up and panels displaceable on guides in horizontal direction, which can be slid from a dikewall like a coupure in case of flooding into an opening, such as a traffic opening, in the dikewall.
- Known embankment devices each have their own disadvantages, such as laboriousness (stacking sandbags or modules), sensitivity to unintended damage or intended sabotage (terror), weakening of a dikewall (slideable panels are slid out of the dikewall) and/or permanent visibility (posts between which baffles are pulled-up).
- the present invention seeks to provide, according to the first aspect, a solid, relatively little laborious embankment device that, at least to a large degree, that can be concealed from the view when the embankment device is as such not in use.
- an embankment device comprising an elongated housing, received in the ground, near and at least substantially parallel to a waterline, with four sidewalls and a bottom, wherein an elongated wall is received being displaceable upwards and downwards between an inoperational state and an operational state and a powered lifting device arranged for displacing the elongated wall upwards and downwards in the elongated housing.
- the ground a natural or artificial upper layer of the local earth surface is meant, such as a dike, a paved quay wall or a part of a riverbed flooded during high tide or permanently flooded.
- the embankment device according to the present invention thus can also be provided under water permanently, to be used as an effective embankment only at specific moments/specific periods.
- a material can be chosen with a suitable combination of the properties coefficient of expansion, cube compressive strength, pH-value and waterproofing, as a result of which the water-repellent elongated wall of the embankment device upon use forms an obstruction being solid and relatively little susceptible to damage for water to be repelled. This is discussed in this document hereafter.
- the possibility is provided to displace the embankment device quickly between a (low) inoperational state and a (high) operational state.
- the embankment device can be received in the ground in such a way that the upper plane thereof (substantially) coincides with the plane of the surrounding ground.
- the upper surface of the elongated wall can be adapted to the structure of the environment, such as a (continuous) pavement pattern.
- the elongated wall can extend until above the surrounding ground surface in the lowered state to form a (semi)permanent wall, such as at seat height.
- the housing is received in the ground by means of a foundation of the housing, wherein the sidewalls or optionally the bottom extend wholly or partly above the ground.
- the device can optionally be reinforced with buttresses or the like on a side of the embankment device turned towards the hinterland.
- the four sidewalls can be designed as a single, composite sidewall, defining a rectangle.
- the elongated housing and the elongated wall are produced from the same material, or at least materials having similar properties, in particular with similar coefficients of expansion. Because the embankment device can be exposed to relatively large temperature differences throughout the year, it is advantageous if the elongated wall and the elongated housing are arranged in similar relationship with respect to each other under different weather conditions. It should be clear that the risk of the elongated wall being jammed in the elongated housing, and thus not or hardly being able to move with respect to the elongated housing, is to be minimized.
- a (too) large distance between the elongated housing and the elongated wall increases the chances of contaminations depositing between the elongated housing and the elongated wall, which can also hinder the displacement of the elongated wall in the elongated housing of the embankment device and in the worst case even block.
- the elongated wall is produced from a material with a coefficient of expansion of at most 0,5 x 10 "6 m/m K "1 at 20 degrees C, further preferably at most 1 ,0 x 10 "6 m/m K "1 at 20 degrees C and even further preferably at most 5,0 x 10 "6 m/m K "1 at 20 degrees C.
- a single elongated wall of an embankment device according to the invention can extend over more than ten of meters and in such a situation "action" (expansion-compression) of the embankment device as a result of temperature differences is to be minimized as much as possible.
- the wall is produced from concrete, preferably high-strength concrete and preferably reinforced concrete.
- Concrete not only has a relatively low coefficient of expansion (the linear coefficient of expansion of concrete at 20°C is 2 x 10 "6 m/m K "1 ).
- Concrete has a high cube compressive strength (> 5 N mm “2 , high-strength concrete > 40 N mm "2 ) without deformation occurring, which is important for being capable of withstanding water pressure without deformation of the elongated wall. Concrete is also relatively robust and therefore the chances of intended or unintended damage thereof are relatively small.
- an embankment device is primarily used when there is a real risk of undesirable flooding, sometimes with severe consequences for the hinterland, the risk of the embankment device being damaged in such a way that water is still allowed to pass through, needs to be minimized.
- an embankment device could be an interesting target for malevolent people.
- Concrete offers a relatively large degree of protection against these things. Another advantage of concrete is that it does not or hardly deform when it is submitted to large forces, such as water pressure of the water to be repelled. Concrete is not or hardly degraded by water, for instance by corrosion or degrading of the material. Moreover, concrete is very maintenance friendly. Concrete further provides the possibility of adjusting the upper surface of the wall, such that the upper surface can be integrated in the surroundings as desired.
- the concrete wall can be incorporated in the streetscape, in case it extends somewhat above the surrounding surface, as a more or less natural building element, for instance as a bank or traffic measure.
- Another advantage of concrete is that, in case of a relatively large impact, it has a tendency to crumble, while other materials often have the tendency to stay intact.
- the risk of a whole elongated wall being dislocated is relatively low with concrete. Local damage in many cases leads to a smaller flooding risk than a full length of an elongated wall being pushed out of the housing.
- the concrete made of conceivable suitable materials can be produced in an environmentally friendly manner and is recyclable.
- the elongated wall preferably produced from concrete, has a thickness of at least 15 cm, more preferably of at least 20 cm.
- the elongated wall can provide a large resistance against pressure when repelling water.
- the thickness of the concrete is somewhat related to the length of the elongated wall, the material the wall is produced from and the optional presence of reinforcing element, such as reinforcement in concrete.
- the minimum height of the elongated wall of course is dependent on the application and a to-be-expected highest level of the water to be repelled.
- the elongated wall preferably has a height of at least 20 cm, more preferably 25 cm and even more preferably at least 40 cm.
- the embankment device is suitable for, at least in the Netherlands, usual minimum heights (25 cm respectively 50 cm) for an embankment device.
- the minimum length of the embankment device is dependent on the application.
- the length of the elongated wall is at least 2 m for being able to efficiently provide a long embankment device.
- the length of the wall corresponds to the distance along which the opening in the vertical construction is to be sealed.
- the embankment device can be constructed a little larger than opening to be sealed and be received on one or both ends in the vertical construction in which the opening is present.
- the amount of embankment devices to be arranged will be inversely proportionate to the length of these devices. It should be clear that the longer the elongated wall, the lower the amount of lifting devices, controls and the like is required.
- the elongated housing and the elongated wall each have a horizontal cross-sectional surface being constant along at least substantially the whole height of the elongated housing respectively the wall, wherein between the outer circumference of the elongated wall and the inner circumference of the elongated housing a space is provided that enables the elongated wall to be displaced upwards and downwards without direct contact with the elongated housing.
- a space is provided that enables the elongated wall to be displaced upwards and downwards without direct contact with the elongated housing.
- the guiding means can be guiding means having a relatively low friction, such as rolls provided on the outside of the elongated wall, and extending slightly outwardly, such that they abut to the inside of the elongated housing and roll over the inside of the housing during the upwards and downwards displacement of the elongated wall in the housing.
- the guiding means can also be provided on the inside of the elongated housing to abut against and roll over the outside of the elongated wall.
- the guiding means can contribute towards minimizing the risk of undesirable tilting of the wall.
- Other guiding means such as rails are also conceivable.
- the guiding means preferably comprise adjusting means arranged for adjusting the guiding means in dependence of the mutual distance between the elongated housing and the elongated wall.
- adjusting means arranged for adjusting the guiding means in dependence of the mutual distance between the elongated housing and the elongated wall.
- a sealing member is provided, providing a seal between the inside of the elongated housing and the outside of the elongated wall at least in the inoperational state or in an operational state.
- a seal between the elongated wall and the elongated housing prevents undesirable material from entering between the elongated housing and the elongated wall and hindering, or even block, a movement of the elongated wall with respect to the elongated housing that is as friction-free as possible.
- a seal optionally can prevent water from undesirably entering between the elongated wall and the elongated housing. Also water present between the elongated wall and the elongated housing could cause decreasing performance of the elongated wall, for instance when there is a chance of this water freezing.
- the sealing member is adjustable between an operational state, wherein it provides the aforementioned seal, and an inoperational state, wherein the sealing member enables a relatively friction-free displacement of the elongated wall with respect to the elongated housing, possibly at the expense of a proper seal.
- This provides the possibility of achieving a decent protection against contamination between the elongated wall and the elongated housing on the one hand and to realize a displacement of the elongated wall with respect to the elongated housing that is as friction-free as possible on the other hand.
- An example of such an adjustable sealing member is an inflatable seal, for instance in the form of an airtight flexible tube provided with an inlet and an outlet valve, wherethrough air can be allowed to enter under pressure or air can be released.
- At least one water supply device being provided in the elongated housing, wherethrough water can be allowed to enter the elongated housing, it is possible to (periodically) fill the space between the elongated wall and the elongated housing with water in order to keep out or remove floating pollution from the respective space. Therein, it is possible to supply water into the space, such that an upward flow in the space is created, which can take pollution from the space outside.
- the at least one water supply device is provided with a nozzle, with which water under pressure can be sprayed into the elongated housing.
- a nozzle with which water under pressure can be sprayed into the elongated housing.
- the amount of nozzles can be adjusted to the length of the elongated wall to provide sufficient cleaning capacity. Pollution thus released, as discussed above, can be removed from the space between the elongated wall and the elongated housing with the upward flow of the water.
- the elongated housing on its inside and/or the elongated wall on its outside is provided with a coating of anti-freeze.
- Anti-freeze coating can be provided in the form of a surface that is water-repellent to such a degree that water can no longer deposit on the coating.
- the coating can have a relatively high coefficient of expansion, at least in the temperature range of +3 to -20 °C, that ice optionally depositing on the coating dislodges from the coating due to expansion and/or compression of the coating.
- a suitable material for such a coating is high-density polyethylene (HDPE).
- the powered lifting device comprises cylinders extending parallel to the sidewalls of the elongated housing, which cylinders are supported at the bottom side by the elongated housing and at the topside of which the elongated wall is supported.
- the lifting device is multi-powered. That is to say, that two or more powered devices are available to the lifting device, such as hydraulic, electric and/or mechanical. This increases the reliability of operation of the embankment device. Failure of the embankment device at times when the embankment device is to be operational can have disastrous consequences and with multiple drives one drive can be used when another drive fails.
- the elongated wall is composed of wall elements aligned with respect to each other, it is possible to provide a relatively large housing, wherein the separate wall elements, preferably with the ends abutting or sealed with respect to each other with sealing members, can be received in a single elongated housing.
- the elongated housing is substantially static, while the elongated wall is dynamic and for that reason there is a wish to construct the elongated wall as a composed wall.
- the elongated wall is displaceable out of the housing up to at maximum 2/3, preferably at maximum 1/2 of its height, the elongated wall is secured against tilting even in the most elevated state.
- the embankment device is arranged for being able to withstand pressure exerted by repelled water, that is to say without further support from one or more reinforcing elements provided at the end of the elongated wall.
- structures that (are to) support the embankment device in an operational state are permanently, visibly present. This is often undesirable. Because of the embankment device according to the invention not requiring such a structure, the embankment device as a whole can remain more or less invisible in the inoperational state.
- an elevation member is provided, produced from a material different from, and/or having a reduced thickness with respect to, the elongated wall.
- the elongated wall itself can exert an amplifying effect on the elevation member, for example because the elevation member extends into the topside of the elongated wall.
- the elevation member can be constructed to have less strength than the elongated wall, because the pressure exerted by repelled water thereon is lower than the pressure exerted at the same moment on the elongated wall, situated lower than, and thus further below, the water surface.
- the elongated housing extends, not parallel to, but perpendicular to a waterline for providing an embankment device comprising an elongated housing with four sidewalls and a bottom, received in the ground, in a waterway and at least substantially perpendicular to a waterline of the waterway, wherein an elongated wall is received, displaceable upwards and downwards in the elongated housing between an inoperational state and an operational state, and a powered lifting device arranged for displacing the elongated wall upwards and downwards in the elongated housing.
- the inoperational state the elongated wall is wholly situated below the water level.
- the topside of the elongated wall is situated above the waterline and the elongated wall closes off the waterway.
- the present invention provides a composed embankment device comprising two or more embankment devices according to the first aspect of the present invention, being positioned mutually aligned.
- a relatively long, for instance kilometers long embankment device can be constructed in parts.
- the present invention relates to an assembly of an elongated housing with four sidewalls and a bottom, wherein an elongated wall is received, displaceable between an inoperational state and an operational state, and a powered lifting device arranged for displacing the concrete wall, arranged for being received in the ground, to be used as embankment device, upwards and downwards in the elongated housing.
- a powered lifting device arranged for displacing the concrete wall, arranged for being received in the ground, to be used as embankment device, upwards and downwards in the elongated housing.
- the present invention relates to a method for providing an embanking elevation of a surface, comprising arranging one or more embankment devices in the ground, according to the third aspect of the invention.
- the embankment devices can be arranged in the ground in a countersunk or partially countersunk manner. I n the first case, they can be arranged in such a way as to be concealed from the view. In the second case, they provide a permanent elevation, possibly an embankment device, which can be elevated in case of flooding risk.
- the embankment device can optionally be used as a permanent embankment device during low tide.
