Description

BACKGROUND OF THE INVENTION
Field of the Invention
The invention relates to an element for receiving and storing water, also known as a storm box or drainage box, having lamellar side panels. In addition, the invention relates to a cleaning arrangement for cleaning such a box, and a method for cleaning such a box.
Description of the Related Art
Liquid receiving, storage and draining structures, also known as a storm box or drainage box, can be used for various purposes. Often, these structures are placed underground for temporarily storing and draining large amounts of water. The structure provides the possibility to collect and store large amounts of water, such as for instance occur as a result of heavy rain fall and the like.
The storage capacity thus obtained provides a temporary relief for the surface and underground, in such a way that flooding and erosion can be prevented or at least mitigated. The water collected in the structure may subsequently be released in a controlled manner, whereby a buffer function is obtained. The release may be carried out in several ways, such as discharge through a sewer, by means of infiltration into the underground etc.
Usually, such structures are built from a plurality of elements that are joined together. The elements used for building up the structure can be modular units which allow for flexibility in building to different sizes. They can include columns and panels which fit together to hold the columns together. The elements typically form a containment structure for receiving the water, having openings towards the surrounding underground, and being surrounded by a geosynthetic, such as a geotextile or a geomembrane, depending on either gradual release or retainment of the water in the structure.
When using the structures are used to gradually release the received water to the soil in which they are provided, a geotextile layer encloses the structure to prevent or limit the access of soil or other contaminants into the structures. However, even if limited, such contaminants can enter the structure with the received water. Soil, sand and other contaminants can gradually become a problem to the storage capacity and also for the flow through of the water. To prevent this problem, the structure can be cleaned with a jet tool and high pressurized water. However, as the openings in the elements to release the water to the surrounding underground are provided parallel to the geotextile, the jet of water that is used usually ruptures the geosynthetic and thereby takes away the functionality of the structure.
It would therefore be desirable to provide an improved structure for receiving and storing water that alleviated some or all of the above problems.
BRIEF SUMMARY OF THE INVENTION
For this purpose, a panel for a system for receiving and/or storing liquid is provided, wherein the panel defines a plane and has openings therein for through passage of the liquid, wherein the openings are defined by a plurality of lamellae, each lamella having a longitudinal direction and a width direction extending between first and second opposite longitudinal edges defining a plane of the lamella, wherein a first lamella is off set from a second lamella in a direction perpendicular to the plane of the lamellae, thereby forming the openings in the panel, and wherein the second longitudinal edge of the first lamella is at least aligned with the first longitudinal edge of the second lamella, such that the lamellae form a closed view in the direction perpendicular to a plane of the lamellae.
The panel is provided with openings for passage of liquid, which is especially important with storage structures that gradually release water to the surroundings. The openings are defined by the offset distance of each pair of lamellae. The second longitudinal edge of the first lamella is at least aligned with the first longitudinal edge of the second lamella, such that only in the direction perpendicular to the plane of the lamellae a distance between the lamellae is created. By forming the openings through the offset of the lamellae with respect to each other, the lamellae are used as shielding of the openings. In at least a perpendicular direction of the lamellae, the panel has a closed view, i.e. the lamellae completely shield the openings. In other directions, the panel may have an open view, i.e. the openings between the lamellae are at least partly visible. At least in the direction parallel to the plane of the lamella, the openings between the lamella are fully visible.
The lamellae can be oriented with respect to each other in several ways, for instance in a slanting way, wherein a first geometric normal of a first lamella and a second geometric normal of a second lamella are at an angle with each other, different from 0 degrees. Preferably, the lamellae are mutually parallel in the longitudinal direction, i.e. wherein the geometric normals of the lamellae are parallel to each other.
According to an embodiment, the first lamella partially overlaps with the second lamella, such that the second longitudinal edge of the first lamella is off set with the first longitudinal edge of the second lamella in the width direction, thereby forming openings between the first and second lamellae. When the first and second lamellae overlap, the range of angles with the perpendicular direction to the plane of the lamella in which the lamellae form a closed view is increased, such that over a larger range of angles of view, the lamellae shield the openings. It may even be so that for this embodiment, the lamellae form a closed view in a direction perpendicular to the panel.
In addition, the lamellae may be slantingly oriented with respect to the plane of the panel. As such, they form slanting lamellae, such as horizontal or vertical louvres.
Alternatively, the lamellae may be oriented parallel to the plane of the panel and the lamella form a closed view in a direction perpendicular to the panel.
The panel may have a first set of edges and a second set of edges that are mutually perpendicular to each other. The lamellae may be oriented parallel to an edge or to the first set of edges of the panel. In that case, the lamellae may be perpendicular to the second set of edges of the panel. As such, the longitudinal direction of the lamella are parallel to the edge or to the first set of edges of the panel. Alternatively, the lamellae may be oriented at an angle different from 0 or 90 degrees with the edge or the first set of edges of the panel. As such, the longitudinal direction of the lamella is slantingly oriented with respect to the edge of the panel.
The panel as described above is in particular suitable for water storage systems, including systems for attenuation of water. Attenuation consists of the temporary storage of surface water in the water storage system below ground level. The stored water is then gradually released in a controlled manner into the soil or into a combined drainage system or watercourse, subsequently effectively reducing the risk of flooding. As such, the panel is particularly suitable for use in an underground system for receiving and/or storing liquid.
The invention additionally relates to an element for use in an underground system for receiving and/or storing liquid, comprising at least one of a base panel and a top panel, and at least one side wall panel extending substantially perpendicular to the base panel and/or top panel, each panel defining a plane, wherein at least one of the base panel, top panel and side wall panel have openings therein for through passage of the liquid, wherein the openings are defined by a plurality of lamellae, each lamella having a longitudinal direction and a width direction extending between first and second opposite longitudinal edges defining a plane of the lamella, wherein a first lamella is off set from a second lamella in a direction perpendicular to the plane of the lamellae, thereby forming the openings in the panel, and wherein the second longitudinal edge of the first lamella is at least aligned with the first longitudinal edge of the second lamella, such that the lamellae form a closed view in the direction perpendicular to a plane of the lamellae. Preferably, at least one of the base panel, top panel and side wall panel is a panel as described above.
According to an embodiment, the longitudinal direction of the lamellae of a first panel is parallel or perpendicular to the plane of an adjacent second panel. The lamellae of adjacent panels may have a parallel or perpendicular orientation to the plane of the respective adjacent panels, the adjacent panels being either parallel or perpendicularly oriented with respect to each other,
The element may comprise a through-going channel having a longitudinal axis, which channel continuously extends from one end of the element to an opposite end of the element, wherein the lamellae extend along the through-going channel. The through-going channel extends within the element, either between two opposite side wall panels or between the top and base panels, or a combination thereof
The invention furthermore relates to a water storage system comprising at least one panel as described previously or an assembly of at least two elements as described above, and a geosynthetic that blocks the passage of soil material, the geosynthetic enveloping the at least one panel or assembly, wherein the lamellae at least partially support the geosynthetic.
In order to be able to store the water in the water storage system having elements with openings in it, the openings are covered with a geosynthetic to be able to keep the water at least temporarily inside the storage system and to keep out unwanted contamination. Geosynthetics are synthetic products usually used in civil engineering.
They are generally polymeric products including eight main product categories: geotextiles, geogrids, geonets, geomembranes, geosynthetic clay liners, geofoams, geocells and geocomposites. Their polymeric nature makes them suitable for use in the ground where high levels of durability are required. They can also be used in exposed applications.
The geosynthetic covers the panel or the assembly preferably at an outside of the panel or the assembly. The geosynthetic may be either supported by the longitudinal edges of the lamellae or by (a part of) the full width of the lamellae, depending on the orientation of the lamellae with respect to the plane of the panel.
Preferably, the system is an underground water storage system. Such an underground water system is placed at a certain depth under ground level and is covered with at least a layer of soil at its top. The geosynthetic is then used both for keeping the water at least temporarily in the storage system, and for preventing soil or other contaminants to enter the system from the surroundings.
The geosynthetic may have a relatively high water permeability that allows the passage of water, such as a geotextile, and wherein the openings between the lamellae for the passage allow liquid to flow into and/or out of the system via the water permeable geosynthetic. Geosynthetics having a relatively high water permeability, such as geotextiles, allow the water to be gradually released from the storage system to the surrounding soil. The water is then allowed to return to underground water courses instead of to the sewerage, thereby preventing a dry-out of the surrounding soil.
Alternatively, the geosynthetic has a relatively low water permeability, for instance a geomembrane or a foil, such that water is kept within the system. In other cases, it is desired that the stored water is transported to the sewerage system or other disposal means instead of releasing it to the surrounding soil. In such cases, a geosynthetic with a relatively low water permeability is used to cover or enclose the panel or assembly.
In an embodiment, the water storage system comprises an assembly of at least two elements as described above, wherein the elements are stacked upon and/or adjacent to each other and the geosynthetic envelopes the assembly.
Preferably, the water storage system comprises box-shaped elements defined by mutually perpendicular flat outer planes having a length direction and a width direction, wherein at least one side wall panel coincides with the length direction and the width direction of a flat outer plane, orienting the length direction of the lamellae along one of the length direction and the width direction of said flat outer plane, wherein the width direction of the lamellae is oriented at an acute angle with respect to the other of the longitudinal direction and the width direction of said flat outer plane.
Moreover, the invention relates to a combination of an element for use in an underground system for receiving and storing liquid as described previously or a water storage system as described above, and a jet tool for cleaning the inside of the element, the jet tool being receivable within the element or the system and having a longitudinal direction which is oriented parallel to a travelling direction of the jet tool within the element or the system, said jet tool having at least one jet nozzle, the jet axis of which is oriented at an angle with respect to the longitudinal direction of the jet tool, in such a way that upon receiving the jet tool within the element or the system, the jet axis of the jet nozzle of the jet tool is oriented in a transverse direction with respect to the plane of the lamellae.
The lamellae of the panels used in the element or in the system form a shield for the geosynthetic against the jet of the jet tool, as the lamellae form a closed view in the direction perpendicular to the plane of the lamellae. The shielding of the lamellae prevents the geotextile to rupture under the force of the jet from the jet tool.
The invention also relates to a method for cleaning an underground water storage system comprising an assembly of elements stacked upon and/or adjacent to each other, said assembly being covered with a geosynthetic, which blocks the passage of soil material, the assembly comprising at least one element having at least one panel defining at least part of the outer contour of the element, the panel having a plurality of lamellae, each lamella having a longitudinal direction and a width direction extending between first and second opposite longitudinal edges defining a plane of the lamella, in which assembly corridors are defined that continuously extend through adjacent elements for passing a jet tool for cleaning the inside of the assembly, said jet tool having at least one jet nozzle, the method comprising:
- introducing the jet tool into the corridor of the assembly;
- orienting the axis of each jet nozzle in a transverse direction with respect to the plane of the lamellae,
- providing a fluid jet from the jet nozzle, such that the jet nozzle impinges the lamellae thereby shielding the geosynthetic from the fluid jet.
The lamellae of the panels used in the element or in the system form a shield for the geosynthetic against the jet of the jet tool, as the lamellae form a closed view in the direction perpendicular to the plane of the lamellae. As the fluid jet is oriented in that direction, the jet impinges the lamellae and not the geosynthetic. The shielding of the lamellae prevents the geotextile to rupture under the force of the jet from the jet tool.
The lamellae may be off-set from each other in a direction perpendicular to the plane of the lamella, thereby forming openings between each other, and wherein a second longitudinal edge of a first lamella is at least aligned with a first longitudinal edge of a second lamella, such that the lamellae form a closed view in the direction perpendicular to a plane of the lamellae, wherein the step of providing a fluid jet from the jet nozzle comprises removing soil or other contaminant from an opening between any two lamellae, such that after cleaning of the underground water system, water is allowed to pass through these openings.
The jet tool is used to clean the system from clogging contaminants. Such contaminants, including soil, may block the openings between the lamellae, thereby blocking any passage of the water through these openings. Especially when a geotextile is used in the system for gradually releasing water to the surrounding soil, such blocking severely hampers the functionality of the water storage system. The jet is then used to remove the soil or other contaminants from the openings between the lamellae, without rupturing the geotextile, such that water is again allowed to pass through.
The lamellae may be shaped as a plate or a strip, each having at least one main surface, the main surfaces of the lamellae being parallel to each other and oriented in a slanting fashion, the method comprising orienting the axis of the jet nozzle transversely, preferably perpendicularly, with respect to said main surfaces of the lamellae.
In case that the lamellae are slantingly oriented with respect to the plane of the panel, the axis of the jet nozzle, and as such the fluid jet, is oriented such that the axis of the jet nozzle is in a transverse direction to the main plane of the lamellae.
Preferably, the method comprises advancing the jet tool along the corridor while providing a fluid jet.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
Figure 1 shows a perspective view of an element 100 for an underground system for receiving and/or storing liquid according to the invention. The element 100 comprises a base panel 101, a top panel 102, and side wall panels 110 extending substantially perpendicular to the base panel 101 and the top panel 102. Each panel 101, 102, 110 defines a plane. All panels 101, 102, 110 have openings 103, 111 therein for through passage of the liquid. The side wall panels 110 have openings 111 that are defined by a plurality of lamellae 112 that have a slanting orientation with respect to the plane of the panel, i.e. the lamellae and the plane of the panel enclose an angle different from 0 degrees.
The element 100 has a longitudinal direction X, a width direction Y and a height direction Z. In the longitudinal direction X, the element 100 comprises two side panels 110 to cover the whole longitudinal side. In the width direction Y, the element 100 is provided with one side panel 110 to cover the transverse side.
Figure 2 shows an interior of the element 100 of fig. 1, having a number of side panels 110 removed. The interior of the element shows that the side panels 110 are used to cover the sides of the element, and that the top panel 102 is supported on the base panel 101 by columns 104 and arched parts 105 extending from one column 104 to another column 104. The columns 104 are attached to the base panel 101 to form a stable structure.
Building an assembly from multiple elements 100 includes placing on top of a first element 100 having a base panel 101 and a first top panel 102, a second top panel 102 on top of the first top panel 102, thereby forming a second element. The first top panel 102 then functions as a base panel for the second element. Both the first and second top panels are supported by columns 104 and arched parts 105. The circular shaped openings 103.1 shows the location where the next set of columns 104 should be placed on the top panel 102 of the first element 100.
The assembly can also be built with elements next to each other, either in the Xor the Y-direction. In such a case, a first and a second base panel 101 are laid adjacent and connected to each other in the same plane, and a first and second top panel 102 are placed on top of these base panels in a similar manner as shown in figures 1 and 2, including that the top panels 102 are adjacent and connected to each other. Each top panel 102 is supported by a set of columns 104 and arched portions 105.
Figure 3 shows a side view of the element 100 from fig. 1 and 2, showing the side panels 110 according to the invention along the longitudinal side of the element 100. Each panel is provided with openings 111 defined by each lamellae pair. The lamellae are arranged such, that in a direction perpendicular to the plane of the panel 110, the panel 110 has a closed view. Each lamella 113 has a longitudinal direction L and a width direction W extending between first and second opposite longitudinal edges 116, 117 defining a plane of the lamella, see also fig. 6 and 7. A first lamella 113.1 is off set from a second lamella 113.2 in a direction perpendicular to the plane of the lamellae, thereby forming the openings 111 in the side wall panel 110, shown in fig. 6. The second longitudinal edge 117 of the first lamella 113.1 is at least aligned with the first longitudinal edge 116 of the second lamella 113.2, such that the lamellae form a closed view in the direction perpendicular to a plane of the lamellae.
The panel 110 comprises side support parts 115 on opposite sides of the panel, the support parts 115 extending from a lower portion to a higher portion of the panel
110. In between the support parts 115, a plurality of support flanges 114 extend from one support part 115 to another support part 115. The plurality of support flanges is distributed along a height of the support parts, the support flanges being spaced apart from each other. The spaces of the panels 110 limited by the support parts 115 and the support flanges 114 are provided with the lamellae 113 that extend between the support flanges 114 in parallel to the support parts 115. Figure 3 clearly shows the closed view formed by the lamellae in a direction perpendicular to the plane of the panel in addition to the closed view in a direction perpendicular to the plane of the lamellae. This is due to the overlapping of the lamellae in their width direction W, as shown in figure 6.
Figure 4 shows a perspective view of a panel 110 according to the invention in which the openings 111 between the lamellae is partly visible due to the rotation with respect to both the direction perpendicular to the plane of the panel and the direction perpendicular to the plane of the lamellae.
Figure 5 shows a cross section of the panel of fig. 4 along line V-V in fig. 4. The lamellae are shown to have a slanted orientation with respect to the plane of the panel 110, i.e. each lamella and the plane of the panel enclose an angle different from 0 degrees. As shown, the first longitudinal edge 116 of the first lamella 113.1 overlaps in the width direction W with the second longitudinal edge 117 of the second lamella 113.2, while the first and second lamellae 113.1, 113.2 are off set from each other over a distance D in a direction perpendicular to the plane of the lamellae. As such the panel 110 has a closed view in both the direction perpendicular to the plane of the panel and the direction perpendicular to the plane of the lamellae.
Figure 6 shows a cross section of another embodiment of the panel according to the invention. The lamellae are shown to have a slanted orientation with respect to the plane of the panel 110, i.e. each lamella and the plane of the panel enclose an angle different from 0 degrees. As shown in fig. 6, the first longitudinal edge 116 of the first lamella 113.1 is in alignment with the second longitudinal edge 117 of the second lamella 113.2 in a direction perpendicular to the plane of the lamellae, while the first and second lamellae 113.1, 113.2 are off set from each other over a distance D in a direction perpendicular to the plane of the lamellae. As such the panel 110 has a closed view in at least the direction perpendicular to the plane of the lamellae.
Figure 7 shows a cross section of another embodiment of the panel according to the invention. The lamellae are shown to have a slanted orientation with respect to the plane of the panel 110, i.e. each lamella and the plane of the panel enclose an angle different from 0 degrees. As shown in fig. 7, the first longitudinal edge 116 of the first lamella 113.1 is in alignment with the second longitudinal edge 117 of the second lamella 113.2 in a direction perpendicular to the plane of the panel, while the first and second lamellae 113.1, 113.2 are off set from each other over a distance D in a direction perpendicular to the plane of the lamellae. As such the panel 110 has a closed view in both the direction perpendicular to the plane of the lamellae and the direction perpendicular to the plane of the panel.
Figure 8 shows a cross section of a further embodiment of the panel according to the invention. The lamellae are shown to have a parallel orientation with respect to the plane of the panel 110, i.e. each lamella extends in parallel to the plane of the panel. As shown in fig. 8, the first longitudinal edge 116 of the first lamella 113.1 is in alignment with the second longitudinal edge 117 of the second lamella 113.2, while the first and second lamellae 113.1, 113.2 are off set from each other over a distance D in a direction perpendicular to both the plane of the lamellae and the plane of the panel. As such the panel 110 has a closed view in both the direction perpendicular to the plane of the panel and the direction perpendicular to the plane of the lamellae.
Figure 9a shows a cross section of the element according to claim 1 and showing in combination the element 100 and the jet tool 120 according to the invention. The jet tool 120 comprises a tool head 124 that is connected to a hose or conduit 123 through which water or another fluid is transported to the tool head 124. The tool head 124 has at least one jet nozzle 122, in this case a plurality of nozzles 122, through which a water jet 121 is forced. The tool head 124 and the conduit 123 are aligned with a longitudinal axis T of the jet tool 120. The water jet 121 and the longitudinal axis T of the jet tool 120 enclose an angle a, such that the water jet 121 impinges on the lamella 113 instead of going through the openings 111 between the lamellae 112, 113, see figure 9b. As a result, the water jet 121 does not impinge or damage a geosynthetic (not shown) enclosing the element.
The jet tool 120 is inserted into the element 100 via opening 103 in the side wall panel 110, the opening 103 and an interior of the element 100 forming a corridor of the element, or multiple elements, forming a water storage system (not shown) with the geosynthetic (not shown). Before inserting the jet tool into the element 100, the axis of each jet nozzle 122 is oriented in a transverse direction with respect to the plane of the lamellae 113. However, with a suitable technique or tool, the orienting can be done after insertion as well.
The water jet 123 is provided from the jet nozzle 122 such that the water jet 123 is at angle a with the longitudinal axis L of the jet tool and impinges the lamellae thereby shielding the geosynthetic from the fluid jet.
The lamellae 112, 113 of the panels 110 form a shield for the geosynthetic (not shown) against the water jet 123 from the jet tool 120, as the lamellae form a closed view in the direction perpendicular to the plane of the lamellae. As the fluid jet is oriented in that direction, the jet impinges the lamellae and not the geosynthetic. The shielding of the lamellae prevents the geotextile to rupture under the force of the jet from the jet tool.
The fluid jet from the jet nozzle removes soil or other contaminant from the openings 111 between any two lamellae 113, such that after cleaning of the underground water system of which the element 100 is part, water again is allowed to pass through these openings 111.
While the invention has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
