Definitions
- the invention relates to a system for water infiltration of rainwater and cleaned, infiltration-compatible industrial water, by means of absorption, intermediate storage and reduced and time-delayed delivery of the water introduced into the water infiltration system, which is to be used in the municipal, commercial, industrial and private sectors.
- PCT / DE97 / 02621 discloses a multi-layer floor area for receiving, temporarily storing and reducing the amount of time that water is discharged into the floor area, the water being drained and throttled above a water-impermeable base seal in a granulate with a high proportion of pores.
- the filter gravel usually used does not allow the trenches to be used below traffic areas or buildings.
- the preferred installation areas for trenches are therefore in residential drainage z. B. below lawns, or in traffic area drainage directly next to the traffic area or, in rare cases, so deep under the base course of traffic areas that are lightly loaded that the load distribution for the trench appears to be acceptable.
- the invention has for its object to provide a rain and process water infiltration system for municipal, industrial, commercial and private applications by means of water absorption integrated in the system, its temporary storage and reduced and temporally extended delivery of the water introduced into the system that use within the traffic areas - Enables construction or under buildings and also allows infiltration of the resulting rainwater as far as possible even with hardly seepable soils.
- a material is required for the absorption, intermediate storage and drainage of the rainwater, which has as high a pore content as possible for the absorption and intermediate storage of the rainwater and which can also permanently absorb the required loads from the expected traffic or the building superstructure.
- the infiltration area must be enlarged to such an extent that complete or extensive rainwater infiltration can be achieved even in very poor soil conditions.
- the subject matter of the invention consists, among other things, of a ballast material that ensures the highest possible proportion of pores under a given load. Due to its secured long-term load and dimensional stability, this water-storing gravel material according to the invention can be used under all surfaces, such as, for. B. streets, parking lots, storage areas, sports facilities, gardens and buildings etc. can be used.
- ballast are known from the relevant regulations for road construction and are described in their physical properties such as load-bearing behavior, grain gradation (sieve line), etc., which, however, cannot fulfill the task related to the invention.
- ballast materials to be used in traffic area construction and derived therefrom which can also be used in building superstructure, are of particular importance for the infiltration system according to the invention.
- the proportion of pores in the storage jacket should be selected to be as large as possible depending on the prescribed load on the surface.
- ballast-forming material has an increased or as high as possible pore fraction in order to be able to absorb, store and derive rainwater or process water from this pore fraction.
- ballast According to the base materials on which the ballast is based, e.g. B. various slags, sandstone, limestone, greywacke, basalt, granite, demolition recycling, etc., result from the different rock properties (especially the strength values are decisive here) for the ballast according to the invention different grain compositions (sieve lines) resulting from the different grain diameters (Gravel rock of a diameter range) and their respective share in the total grain mixture (ready-to-install gravel) result and, depending on this, result in different pore proportions (cavity between the individual rock grains forming the gravel).
- the shape of the crushed stone plays an important role.
- Rounded rock such as B.
- the gravel used in trenches cannot form a bond with one another, since the smooth stone surfaces do not get caught and can therefore slide against one another under load, which forbids installation under paved surfaces.
- the shape of the broken rock also has a significant influence on the proportion of pores.
- crushed crushed stone has been used for many decades, the sieve line of which ranges from very small grains of a few thousandths of a millimeter to grains common today of around forty-five millimeters or occasionally larger.
- ballast must ensure that the storage body formed therewith flows properly and with as little resistance as possible.
- gravel grains should therefore be used which only start with a diameter of several millimeters.
- At least one other of the aforementioned parameters must be changed in order to ensure an optimally pore-rich ballast.
- ballast base material of the nearest quarry or other gravel source It is sensible to adapt the ballast generally over the grain size range and the sieve line arranged between the smallest and the largest grain, since the load capacity is mostly an unchangeable external specification and the rock values are unchangeably specified by the ballast base material of the nearest quarry or other gravel source.
- the dwell time of the water in the ballast base layer must be taken into account in the frost-related considerations, since a retention space without at least a restricted flow can also cause frost to break out if the retained water freezes from above and compensates for the volume is accordingly no longer possible in remaining cavities.
- frost-related considerations since a retention space without at least a restricted flow can also cause frost to break out if the retained water freezes from above and compensates for the volume is accordingly no longer possible in remaining cavities.
- the grain structure can be reinforced using binders such as cement, bitumen, adhesive or the like.
- the gusset is artificially widened in this way and its pressure load can be subjected to a higher load in accordance with the strength values of the binder, and the gravel grains are additionally connected to one another in a manner that prevents dislocation.
- the open-pore structure of the ballast according to the invention also leads to the likewise important ability of the water to be introduced and discharged into and out of the ballast.
- ballast according to the invention can also be used ideally for infiltration systems such as trenches, pipe trenches and the like, since in combination it can directly fulfill the task of the base course according to the invention and can thus contribute to considerable savings in the production of infiltration systems.
- the invention-related gravel in areas with z. B. very infiltrating soil conditions such. B. be a trough and below a traffic area
- the rainwater accumulation, z. B. by means of a drainage system absorb, distribute and infiltrate towards the subsoil as a new embodiment of a trench or pipe trench that can withstand high surface loads.
- the necessary civil engineering work and the need for building land can thus be significantly reduced, since the infiltration would be integrated into the already area-intensive traffic area structure (e.g. streets, paths, squares, storage areas, carport, garages, terraces, under buildings, etc.), which accordingly, nature-identical, large infiltration areas possible.
- the ballast should be installed as flat and broad as possible to prevent unnecessary excavation to create the largest possible infiltration.
- the material of the storage jacket will, in accordance with the previous explanations, in most applications in the course of road construction measures be crushed stone, fine split, broken gravel or another bulk material.
- the installation as close as possible to the surface also has the further important advantage that the prescribed groundwater distance can be maintained even with high groundwater levels.
- the road or square structure and its road surface can be designed as desired in all of the infiltration systems according to the invention, since the infiltration system according to the invention, depending on the infiltration possibilities of the soil in question, as a rule only requires a smaller amount of space, as it does for the planned traffic areas is provided anyway. It goes without saying that the small amount of space and installation effort required for the subject matter of the invention also permit subsequent, problem-free installation in existing traffic areas. Subsequent installation is particularly recommended when refurbishing base courses, as ramshackle rainwater canals can also be replaced in one operation.
- ballast storage In most applications, it will not be sufficient to only install the ballast storage in order to achieve a quick and even rain or process water distribution. Rather, it will be the rule that there is a combination of the ballast storage with a drainage pipe (remotely comparable to a pipe trench) or drainage pipe system.
- the drainage pipes can within z. B. consist of several connected, largely parallel drainage pipes, ring lines or a central pipe with one- or two-sided drainage pipe branch.
- the drainage pipes are usually arranged somewhat above the trench bottom in the filter gravel.
- the drainage pipes are placed directly on the geotextile on the ground and then completely covered over with the storable ballast. Due to the deep arrangement in the pipe trench, it is ensured that if the sediments are flushed out, the deepest storage ballast areas can also be covered by the cleaning. Such cleaning is not possible with the known tubular trenches.
- a planum optimally prepared for the introduction of water by means of flow technology simplifies the simple and precise laying of the drainage pipes, which can only be achieved to a limited extent with pipe trenches, since the drainage pipes of a pipe trench applied to the hardly compressible layers of filter gravel can only be laid straight to a limited extent.
- the infiltration system When installing in descending or ascending terrain, the infiltration system must be created from several submerged infiltration areas, which can also be interconnected, due to the horizontal distribution of the discharged water. As a rule, it will be sufficient for a partial area composite to connect the drainage pipes or drainage pipe systems by means of at least one overflow and / or throttle shaft. If the soil infiltration values are extremely poor, an emergency overflow into downstream systems such as e.g. B. rainwater retention basins, storage canals, canals, ditches, streams and rivers, etc. are unavoidable.
- the combination of a small drainage pipe and surrounding storage body made of void-rich material can also have a positive influence on the water distribution within the infiltration system.
- ballast in particular, it should be noted that the water flowing through does not cause a negative redistribution of grain within the storage jacket. If this is to be expected, the storage jacket material can be secured against grain redistribution with a binding agent that binds the grains together.
- the ballast reservoir which forms the supporting layer of the traffic area, in order to be temporarily stored there and to be seeped away over a large area over the raw subgrade. If the inflow of water diminishes, the raw planum is first drained by infiltration through the raw planum and only at the end the somewhat deeper pipe trenches.
- the infiltration system, drainage pipe and ballast storage can also be placed on an almost equally high ground level if this seems sensible to fulfill the infiltration and load absorption. This can e.g. This can be the case under buildings, for example, since the drainage pipes arranged underneath a floor slab made of proven concrete are generally not exposed to impermissible loads.
- Corresponding computer programs in particular enable the user of the invention to plan and manufacture an infiltration system according to the invention which is to be adapted precisely to the expected rain events as well as to the soil parameters and the space-related installation requirements.
- the computer programs allow an exact determination of the size or storage volume of the required ballast storage depending on the infiltration area resulting from the soil values.
- ballast tank is sufficient. If the infiltration values are low, the ballast storage and the infiltration area must be increased accordingly. There is thus a correlation between the amount of water that has to be stored temporarily and the infiltration capacity of the soil and possibly other drainage devices.
- the object of the invention can generally be dispensed with if the infiltration values of the soil underneath the trough are better than that of the busy soil zone of the trough. However, this is very rarely the case.
- the storage body is to be protected against dirt penetrating from outside, which would restrict the storage volume, with a covering or layer of preferably pressure- and filter-stable geotextiles or materials that can perform this task equally well.
- a water-impermeable separating layer should be provided in the edge area of the infiltration system, or of infiltration sub-areas, where a lateral discharge of the temporarily stored water is rated as critical, in order to protect adjacent layers of normal ballast or uncontrolled outflow of rain or process water into lower-lying infiltration sub-areas. So that it is ensured that the infiltration or water discharge can only take place vertically through the rough subgrade.
- the edge area can be provided with a separating layer made of preferably foils or fabric sheets with sealing compounds (bentonite sheets) or materials that perform this task equally well can such.
- the cladding materials of the ballast store create yet another advantage. If the construction project on cohesive soils such. B. Loam erected, a geotextile supports the dimensional stability of the cohesive subsoil to a considerable extent and thus secures traffic areas or building foundations against subsequent subsidence. Geotextiles also prevent the penetration of layers of soil that have been wet due to frost due to frost due to frost-prone subsoil, so that a high safety reserve is made possible in frost prevention.
- the water flowing into the water pipe can come from all possible systems.
- But canals, drainage ditches and infiltration systems can also be done with the line, e.g. B. in the event of overcrowding in the area of the emergency drain.
- heating systems can e.g. B. can be integrated as electrical, hot water or hot air lines in the infiltration system or operated externally via the drainage pipe with blown warm air.
- Preventive protection against freeze-thaw changes for the percolation system according to the invention which are installed within the area at risk of frost can also be achieved in that Devices are installed in the area of the inlet which close the line in the event of frost in order to prevent the inflow of water into the ballast tank, which may be at risk of frost.
- the disadvantage would be that in this case the water (usually only the relatively small amounts of condensation) would run off above ground, which is not very welcome by the municipalities.
- this problem generally affects all infiltration systems, in particular those that are supposed to release their rain or condensation water to the subsoil via open trough systems and is not specific to this invention.
- the infiltration system according to the invention also fulfills its positive purpose in ecological water treatment, since the open-pore ballast storage forms an excellent space for the settlement of pollutant-consuming microorganisms.
- the possibility of microorganism cleaning can be further intensified if pollutant-specific microorganisms are supplied to the infiltration system via the drainage pipe or pipe system and additionally supplied with fresh air blown in.
- the temperature gradient in the ballast layer itself ensures a low convection flow of air between the ballast grains, which can support a well-functioning micro-organic cleaning.
- the contaminated infiltration section can be closed when a damage occurs and can be excluded from the infiltration network for the time of cleaning, so that the damage is limited to a small area.
- the drainage pipe or the drainage pipes within the loaded ballast store can be equipped with an inlay hose to seal the drainage openings until the surrounding ballast store has been restored to a harmless state.
- FIG. 1 shows a cross section through a paved traffic area with adjacent trough infiltration
- Fig. 2 shows a cross section through a paved traffic area with adjacent trough / pipe infiltration
- FIG. 3 shows a cross section through a paved traffic area with a single-pipe area infiltration
- FIG. 4 shows a longitudinal section through a paved traffic area with a cascade-shaped area infiltration system
- Fig. 5 is a grain structure from a void-rich gravel with a graded screen line
- Fig. 6 provide the ballast from Fig. 5 with a load-bearing binder
- the infiltration system (10) shown in Figure 1 consists of a water-cleaning trough (34), in the passage of which the water is largely freed of pollutants. Below this is the primary infiltration area (36) of the infiltration system (10), which had to be designed very flat due to the high groundwater level.
- the infiltration system (10) is expanded with an additional ballast reservoir (37) lying on the raw planum (44) directly below the conventional ballast base layer (24).
- the flat ballast storage structure (36, 37) requires a correspondingly large base area (20) on the formation (44), which is used for additional infiltration (37) in heavy rainfall, so that there is no need to drain rainwater into downstream drainage systems.
- the watertight side separating layers (38) made of bentonite sheets attached on both sides prevent rainwater from penetrating into the conventional road structure even in heavy rain events (24, 29).
- the overlaps (17) of the separating layers (38) are to be designed so far that, due to the hydraulic pressure arising in the infiltration system (10), there are no underflows and the associated unwanted water outflows.
- FIG. 2 shows an infiltration system (10) comparable to FIG. 1, in which the infiltration possibilities of the existing soil (35) are assumed to be even worse than in FIG. 1.
- a drainage pipe (13) is installed directly under the trough (34) inside the ballast reservoir (36,37) to pass on water that cannot seep in due to the soil conditions. Before the infiltration system (10) is flooded, the excess rainwater is sent to a downstream drainage system (e.g. a channel). Since the drainage pipe (13) was arranged below a trough (34), which must not be driven on due to its infiltration function, the minimum overlap between the drainage pipe apex of the drainage pipe (13) and the trough surface did not have to be observed.
- the raw planum production (44) of the primary infiltration space (36), which also serves as drainage pipe bedding (43), could be arranged so high that the prescribed groundwater distance between the raw planum (44) of the infiltration system (10) and the maximum groundwater level was maintained could be.
- the drainage pipe (13) can be dispensed with if the extended infiltration area (37) is extended so far below the road body (24, 29) that an overflow for excess rainwater that may be generated is superfluous via the additionally obtained infiltration area becomes.
- FIG. 3 shows in its street cross section a direct discharge of street wastewater and house drainage (47) (not shown), without a water-cleaning trough passage, via a street-accompanying trough channel (40) and correspondingly arranged processes (26) (not shown) and discharges (51 ) (not shown) on a drainage pipe (13) that was installed in a pipe trench (42) with a sufficient depth to create the required covering height. Due to the higher pressure load on the drainage pipe (13) due to the volume of traffic, it was laid in accordance with regulations on a pipe bedding (43) made of sand. In this example, the pipe trench (42) only forms a small proportion of the ballast storage and the infiltration area (20).
- the ballast reservoir in the pipe trench (42) is filled very soon and the rainwater then distributes itself to the right and left depending on the slope situation when it reaches the top of the pipe trench, thereby increasing the infiltration area (20) and reaching the watertight one Separating layers (38) continue to rise over a large area in the ballast store (14).
- the drainage pipe (13) which introduces and distributes rainwater is connected at its deep end to an overflow (27) into a subsequent drainage system (not shown) for the discharge (50) of rainwater amounts not provided.
- FIG. 4 shows a longitudinal section through two seepage subareas (12) arranged in a cascade arrangement below a road (21) with a steep longitudinal gradient.
- the infiltration partial surface (12) arranged above on the left in FIG. 4 draws its rainwater via a drain with wet sludge trap (26), from where the water after sediment separation via a sewer pipe (50) as a feed line (51) in the drainage pipe (13) the infiltration partial surface (12) ends.
- Another rainwater inlet is via the house connection (47) shown.
- the drainage pipe (13) is parallel to the roadway (21), or rough planum of the road (49), which also represents the infiltration surface (49), at a depth which corresponds to the prescribed coverage height. Due to the steep gradient, this means that the inflowing rainwater flows to the end of the drainage pipe (62) and only after the subsequent watertight separation layer (19) made of bentonite sheets does the water accumulate in the ballast reservoir (14). Since the void-rich ballast store (14) does not provide any appreciable flow resistance to the inflowing water, the rising water is distributed quickly and almost without back pressure in the infiltration area (12). A large storage volume (14) is required for the lower partial infiltration area (12), in FIG.
- FIG. 5 shows storage ballast material (14, 36, 37), consists of compacted gravel grains (53) of different diameters in the area of the sieve line 8/32 mm, which can be used very well, with its sieve line to create a maximum pore space (54) on small particles less than 8 mm is completely dispensed with.
- the enormous areas of the comm boundaries (55) offer an ideal floor for a microorganical cleaning film.
- the ballast (14,53,54,56) is evenly filled with accumulated rainwater (57).
- FIG. 6 shows the same grain structure (53, 54, 56) as in FIG. 5, with the difference that in order to increase the load-bearing capacity, the ballast (14) was poured over with an aqueous cement which concentrated in accordance with the surface tension of the liquid cement has settled on the gussets (60).
- the entire gravel grain (53, 56) outside the gusset (60) is only thinly coated by the binder (59).
- a further base layer consolidation takes place through the additional incorporation of the free gravel grains (56) in the composite.
