Definitions

  • the invention relates to a paving element manufactured from water-permeable material.
  • Such paving elements are, for instance, known from Dutch patent application NL-A-9301143.
  • the paving elements described therein are provided with an upper water-permeable layer and a lower watertight layer.
  • the known paving elements are particularly intended for paving large surfaces, such as streets, sidewalks, squares and the like. They have the advantage that the water is not left on the upper surface of the paving element but directly sinks into the paving element, until it reaches the watertight layer.
  • This watertight layer is preferably somewhat inclined, so that the water within the paving elements flows in a specific direction, preferably to a drain. The drains carry the water to the sewer.
  • DE-A-40 22 568 discloses a fully water-permeable paving element.
  • a wadi is an area which in case of heavy rainfall is allowed to flood so as to form a kind of buffer for the excess rainwater. In periods of drought these wadis serve as buffer for keeping up the groundwater level.
  • Dewatering installations for streets in the form of drains are known from practice.
  • the inlet openings of these drains are situated near the longitudinal edges of the street in the so-called upright course of the street.
  • the drains are provided with a first discharge possibility by infiltration from the drain to the ground.
  • the excess water can be carried via an overflow to a rainwater pipe.
  • the rainwater pipe which carries the water for instance to a pond, ditch, wadi or the like, can no longer cope with the water, the water is discharged to the sewer by means of a second overflow.
  • a drawback of this known construction is that infiltration of rainwater into the ground takes place only at the drain. Consequently, a relatively small infiltration area is available.
  • Another drawback of the known installation is the cost price of the specifically designed drain and the pertaining rainwater pipes with overflow possibilities to the sewer pipes.
  • the known construction is so expensive that it is not yet frequently used in practice.
  • the street must be broken up to install the rainwater pipes and the different overflow provisions. This involves considerable cost and additionally causes a lot of traffic trouble.
  • the invention has for its object to provide a water-permeable paving element, so that the water can penetrate into the underground, which also has the possibility of discharging the excess rainwater in case of very heavy rainfall, without requiring the above expensive construction.
  • the invention therefore provides a paving element manufactured from water-permeable material, a pipe section provided with at least one inlet opening being included in the paving element, the pipe section being connectable to a first water discharge system, and the at least one inlet opening being provided in the paving element.
  • the water permeability of the material from which the paving element is manufactured naturally offers some resistance to the permeation of water.
  • the extent of this resistance depends on the amount of open space in the material. In case of much open space the resistance will be low, while in case of a small open space the resistance is higher.
  • the amount of open space in the material depends, inter alia, on the size of the particles from which the material is built up.
  • the pipe sections must be connected to a water discharge system.
  • a water discharge system may, for instance, lead to a pond, a ditch, a wadi, an infiltration pit or such a water reservoir.
  • the water discharge system may also be connected to the sewer.
  • an overflow pipe is connected to the pipe section, a part of the overflow pipe extending above the level of the inlet openings, and the overflow pipe being connectable to a second water discharge system.
  • an overflow pipe is connected to the pipe section, it becomes possible to discharge the rainwater in three ways.
  • the rainwater will penetrate into the underground via the permeable material of the paving element.
  • the first water discharge system can lead the water, for instance, to a ditch, a pond, a wadi and/or an infiltration pit.
  • the rainwater remains available for use at a later time, during a period of drought, for irrigating the land, or in the case of wadis or infiltration pits, for gradual uptake in the underground.
  • This second water discharge system may, for instance, be formed by the sewer.
  • the paving element may be provided with a first pipe section having first inlet openings and a second pipe section having second inlet openings, the first inlet openings being situated at another level between a lower side and an upper side of the paving element than the second inlet openings, the first pipe section being connectable to a first water discharge system, and the second pipe section being connectable to a second water discharge system.
  • the dimensions of the paving element are such that it can be placed in the position of the upright course of a street.
  • Such paving elements can simply be fitted in with existing infrastructure without requiring the removal of the road surface. Consequently, only very few infrastructural operations are necessary, which considerably limits the required investments.
  • the paving elements can be laid in series with the end faces against each other, at the same time a connection being effected between the pipe sections of the successive paving elements, so that a pipe is formed.
  • the successive paving elements are somewhat inclined, so that the water in the pipe formed by the successive pipe sections automatically flows in a specific direction.
  • sand collecting pits may be provided every so many meters between two successive paving elements, so that sand particles included in the water-permeable material can migrate to the sand collecting pits through the water-permeable material of the paving element.
  • the invention also relates to a street provided with a series of paving elements according to the invention, the pipe formed by the interconnected pipe sections of the series of paving elements lying with the end faces against each other being connected to a water discharge system or, when the pipe sections of the paving elements are connected to an overflow pipe, or when the paving elements are provided with first and second pipe sections, being connected to a first and a second water discharge system.
  • DE-A-44 28 482 discloses a paving element provided with an internal pipe section or at least a throughbore for discharging excess water to a water discharge system.
  • this known paving element is not manufactured from water-permeable material. Via passage openings between two successive paving elements water can flow into the underground, and in case of a large water supply water can be discharged via the throughbore in the paving element to the water discharge system. It may be clear that such passage openings can be easily clogged, so that discharge of rainwater to the underground or the throughbore is fully prevented.
  • the exemplary embodiment shown in Fig. 1 shows a cross-sectional view of a paving element B manufactured from water-permeable material 1.
  • the water-permeable material 1 may, for instance, be polymer concrete having an open structure.
  • Included in the paving element B is a pipe section 2 provided with a number of inlet openings 3.
  • the paving element B shown in the present exemplary embodiment has a form suitable for being placed in the upright course of a street 8. The successive paving elements B then come to lie with the end faces against each other, with the different pipe sections 2 of the successive paving elements B being interconnected. There is thus formed a pipe connectable to a water discharge pipe system.
  • a water discharge system is a pipe system, such as for instance the sewer, or a pipe system leading to a pond, a wadi, an infiltration pit or a ditch.
  • a water discharge system may also be formed by a basement box, which is a reservoir through which the water can slowly infiltrate into the ground.
  • the water discharge system may also be formed by a perforated pipe driven deeply into the ground, so that the water can infiltrate into the ground via this pipe.
  • Fig. 1 diagrammatically shows a basement box 6, although not to scale with respect to the paving element B.
  • Connected to the pipe section 2 is an overflow pipe 4.
  • a part of the overflow pipe 4 extends above the level of the inlet openings 3.
  • the overflow pipe 4 is connectable to a second water discharge pipe system.
  • the second water discharge pipe system may, for instance, be formed by the sewer.
  • the paving element B of the present exemplary embodiment is provided at the upper side with a filter layer 5, which prevents the water-permeable material 1 of the paving element from being clogged with street garbage.
  • the filter layer 5 can, for instance, be built up from polymer concrete having a granular size less than 3 mm.
  • the granular size of the water-permeable material 1 may, for instance, range between 4 and 10 mm.
  • Fig. 2 is a cross-sectional view of a street 8 provided on both sides with paving elements B according to the invention. It should be noted that the ratio between the width of the street 8 and the size of the paving elements B in the present drawing is not in agreement with reality.
  • the width of the paving elements B shown in Fig. 2 is such that they can be positioned in the upright course of the street 8. Clearly visible are the water-permeable material 1, the filter layer 5 and the cross section of the pipe 2.
  • the street surface is somewhat inclined, so that the rainwater falling on the street 8 flows to the paving elements B.
  • Fig. 3 is a cross-sectional view of a paving element B positioned in the upright course of a street.
  • the cross section of Fig. 3 is taken at a drain or gully 7.
  • the overflow pipe 4 of the paving element B opens into the drain 7.
  • Fig. 4 shows a variant of the street 8 of Fig. 3, a sidewalk 9 being arranged along the street 8. Positioned in the sidewalk 9 as well as in the street 8 is a series of paving elements B' and B, respectively.
  • the pipe 2' of the paving element B' situated at the sidewalk 9 opens into another water discharge system than the pipe 2 of the paving element B located in the upright course of the street 8. Only in case of very heavy rainfall such that the overflows 4' and 4 become active, the excess water from the sidewalk 9 and the street 8, respectively, will be discharged into the drain 7.
  • Fig. 5 is a cross-sectional view taken on the line V-V from Figs. 7 and 8.
  • Fig. 6 is a cross-sectional view taken on the line VI-VI from Figs. 7 and 8.
  • Fig. 7 is a cross-sectional view taken on the line VII-VII from Fig. 5, and
  • Fig. 8 is a cross-sectional view taken on the line VIII-VIII from Fig. 6.
  • the exemplary embodiment B2 shown in these figures is manufactured from water-permeable material 11. At an upper side the paving element B2 is provided with a filter layer 12.
  • the filter layer 12 is also water-permeable but has a finer granular structure than the water-permeable material 11 so as to prevent clogging of the water-permeable material 11 with street garbage.
  • the paving element B2 of this exemplary embodiment is provided with a first pipe section 13 having first inlet openings 14.
  • the paving element B2 further contains a second pipe section 15 having second inlet openings 16.
  • the first pipe section 13 is connectable to a first water discharge system such as, for instance, a basement box, an infiltration pit or a pipe system leading to a pond, a ditch or a wadi.
  • the second pipe section 15 is connectable to a second water discharge system which is, for instance, formed by the sewer.
  • the first inlet openings 14 are situated at a lower level within the paving element B2 than the second inlet openings 16.
  • the pipe sections 2, 13, 15 are provided at one end with a socket 2a, 13a, 15a in which the other end of the corresponding pipe section of an adjacent paving element B, B2 can be fittingly received.
  • the paving elements B, B2 may be provided at one end face thereof with a tongue and at the other end face thereof with a mating groove, so that mutual displacement of paving elements B, B2 lying with the end faces against each other is prevented.
  • the operation of the paving elements shown is as follows: when it is raining gently and there is therefore a moderate supply of water, the water from the street 8 or the sidewalk 9 will flow to the paving elements B or B2. As a result of the water permeability of the filter layer 5 or 12 and the water-permeable material 1 or 11, the water will be able to penetrate into the underground via the paving elements B, B2. The underground takes up the water, so that desiccation or a drop in the groundwater level is inhibited. Because paving elements permeating water to the underground are arranged over substantially the entire length of the street, no concentration of pollution takes place. The self-cleaning action of the soil can therefore be optimally utilized.
  • both exemplary embodiments B, B2 provide the possibility of discharging the excess water to a second water discharge system.
  • this possibility is created by connecting an overflow pipe 4 to the pipe 2.
  • the overflow pipe 4 can open into a drain, so that the excess water can be discharge via the drain and the sewer system connected thereto.
  • This second pipe section is provided with inlet openings 16 which, however, are situated at a higher level in the paving element B2 than the first inlet openings 14. Only when the water level within the paving element B2 has risen to the level of the second inlet openings 16, the second pipe section 15 will be filled with excess water which can be carried to a second water discharge system.
  • a closing layer may be arranged at the bottom and, if required, at the sides of the paving element B, so that the paving element essentially forms a kind of gutter.
  • a closing layer may, for instance, be formed by a film or by a layer of very fine-granular polymer concrete.
  • the water permeability of the materials 1 or 11 can then be used to carry water in the longitudinal direction of the paving element to a collecting point, such as, for instance, a basement box or an infiltration pit.
  • the inlet openings 3, 14, 16 are formed by inlet openings of pipe stubs perpendicular to the pipe sections 2, 13, 15, it is also possible that the inlet openings are formed by throughbores in the walls of the pipe sections 2, 13, 15. It is even possible that the pipe section is formed by a throughbore in the water-permeable material, only the lower side of the throughbore being made watertight, for instance by means of a coating, so that a kind of gutter is formed in the paving element. The inlet opening is then formed by the still water-permeable upper side of the throughbore. The upper edge of the watertight lower side of the throughbore then forms the boundary of the inlet opening.
  • a paving element B which is not provided with an overflow pipe 4 or a second pipe section 15 for discharging excess water to a second water discharge system, but which is provided with a single pipe section for discharging water to a first water discharge system, also falls within the scope of the present invention.
  • the paving element according to the invention is further eminently suited for use in a water-permeable road surface which is provided at the lower side with a closing layer. In such a road surface the water falling thereon will flow via the closing layer to the paving element where it can penetrate into the paving element via a side wall of the paving element.
  • the application possibilities are not limited to streets but also comprise squares, promenades and the like. Furthermore, installation in the middle of the street, instead of at the upright course, is within the bounds of possibility.
