Definitions
- Typical for the construction of a dike is its trapezoidal cross-section.
- the dike body is usually made of compacted earth or building materials with a solid, well-rooted grass or a mixture of different earth and building materials.
- slope slopes should be 1: 3 or more shallow, which also brings with it advantages in terms of maintenance and necessary measures against tilled animals.
- the slopes usually have inclinations between 1: 2 to 1: 3, while on coasts, the slopes can be at least flatter on the lakeside.
- the height of the crest of the dykes is essentially based on the choice of the flood as an event with a certain likelihood of occurrence (recurrence in a certain period of time) relative to a certain water level. It is calculated from the high water level and the so-called freeboard (additional altitude for Windstau of the water, wave casserole on the embankment, if necessary influence of ice accumulation and a security surcharge). In the new construction, an additional surcharge for the setting of subsoil and dyke body added.
- the three-zone dyke cross-section has proved to be the ideal dyke structure with regard to stability in the event of long-lasting flooding:
- a permeable ground support with a water-side wedge of impermeable earth material which can be used to extend the flow path with a sealing wall (diaphragm wall, narrow wall, sheet piling) into the subsurface under the dike or in a deeper dense layer binds.
- a dyke is known, for example, from WO 00/34587.
- a water-impermeable barrier is provided, which extends along the dyke longitudinal direction and in height to below the dike crown. The barrier is positioned approximately midway between the two slopes.
- the barrier is constructed in several parts and has a water-impermeable membrane made of a synthetic material in the middle. Lateral the membrane is fixed in a bellows-like folded membrane section in a foundation.
- a dike decking for securing the slope is provided against ingress of water. This purpose is served by a multi-layer, water-impermeable membrane anchored in the slope.
- the protective wall has a surface, plate-shaped or cubic training, which has a portion of a water-impermeable building material.
- the building material of the protective wall is a combination of compacted, mineral aggregates and an organic adhesive. Mineral aggregates such as sand or gravel are abundant building materials in nature and can be procured locally in a simple and inexpensive way in large quantities. Mixed with an organic adhesive, the building material can be easily applied and processed in viscous consistency. By appropriate shaping, the protective wall can be made many times curved in many dimensions.
- the good flowability is of great importance for processing.
- the building material In the uncured state, the building material has a higher flowability (consistency class) than fresh concrete in most combinations.
- an adhesive that is curable under the influence of water.
- suitable adhesives are two-component epoxy resin, one-component polyurethane or two-component polyurethane adhesive.
- the granulation of the additives is preferably between 0.1 and 0.3 mm. Within this range there is still a good watertightness without the screening of the building materials would have to be limited too much.
- the permeability coefficient kf of the building material ideally amounts to a maximum of 5x10-10 m / s. If larger particle sizes are used, the water permeability increases.
- the protective wall is then suitable as an arrangement in the embankment area of a dike as a water floor and shore protection and helps to work against erosion in coastal and shore area, is slowed down and absorbed in the waves or the wave casserole.
- Favorable particle sizes of the additives are in this case preferably between 2 to 150 mm.
- the density of the protective wall which is higher than that of water and, if appropriate, can be increased and varied by adding steel. This effectively prevents floatation of the protective wall, especially in the surf area.
- Another advantage lies in the environmental compatibility of the building material.
- the building material has no toxic effect on molds and is considered microbially difficult to degrade. Nevertheless, substances that can be eluted from the protective wall can be well degraded, as material trials have shown. As washing tests prove, there is no chemical interaction between water and the constituents of the building material. Thus, the protective wall can even be used in dams and delimitations for drinking water reservoirs.
- the flooring according to the invention can be disposed of after its use phase in a soil or gravel washing system without adverse environmental effects. Alternatively, after comminution, reuse as granules is also possible.
- the wall thickness d w of the protective wall is smaller than the extension in height h w and length lw.
- mat-shaped protective walls can be produced on site with glued gravel, and then lowered into the water on a flowing pontoon to protect the water floor against erosion [harbors, sheet piling etc.].
- Protective walls with a maximum length of 40 m, a width of up to 25 m and a thickness of up to 50 cm could be prefabricated at the construction site.
- the object is achieved by the features of claim 12.
- the dike has a dike body with a substantially trapezoidal cross-section. Between the inner and outer embankment a dimensionally stable protective wall is provided, which extends in Deichlhacks- and height direction, wherein the protective wall is designed according to one of the embodiments described above.
- the protective wall acts as a seal.
- the seal reduces the leachate and contributes to the stability of the dike.
- Possible water-side surface seals as they are explained later to the alternative solution of the object of the invention according to the features of claim 15, and core gaskets (inner gaskets).
- the protective wall in the dike body runs vertically from the dike crown through the dike cross section and ideally binds into a dense soil layer underlying the dyke.
- the protective wall avoids an underflow of the dyke, which material movements and other erosion, which make the dyke more unstable, would result.
- Such a sealed dam can be made with steeper angles of slope, which can reduce the dike cross section, which is an additional advantage in limited spatial conditions.
- an asymmetrical positioning of the protective wall is possible with an offset to one of the two slopes, wherein the water-side positioning further reduces erosion in the waterside embankment.
- Protective walls can also be retrofitted into existing dike structures and represent a simple and economical method for upgrading or repairing dykes.
- the dike has a raised dike body with a water- and landside embankment, whereby the embankment on the water side forms an embossed body.
- resistant protective wall is upstream.
- the protective wall is designed according to one of the embodiments explained above.
- Favorable angles of inclination ⁇ of the protective wall with respect to the water surface are between 15 and 90 degrees, wherein the angle of inclination ⁇ may be different from the angle of repose ⁇ if, for example, the protective wall is offset from the embankment, is designed separately.
- this can be secured by an additional base in the dike area, the embankment and / or in the ground.
- the dyke according to the invention has the advantage that when positioned close to the shore or on the coast and in dykes with deep lying narrow foreland an effective slope protection is given.
- a closed, dense and strongly rooted sod provides for dikes i.d.R. a sufficient and economical slope protection against flow and wave attack.
- flotsam for example also tree trunks, in the winter possibly drifting ice floes and ice accumulation. This also applies to frequently recurring high and long-lasting water levels.
- a further seal against underflow and leakage can be achieved by extending the protective wall from the dike body to the ground.
- the invention enables the construction of steep slopes (steeper than 1: 3), as it protects the dike body from damage when designed as a planar fuse.
- a heavy and water-permeable protective wall is required as an (open) revetment for reasons of stability.
- the water permeability of the protective wall can be determined. If the protective wall is designed to be permeable to water, as for the above insert wall, then grain sizes for the mineral aggregates of about 2 mm above will have to be used. For a water-impermeable protective wall, the grain size is correspondingly lower.
- a dike with a protective wall which extends into the dike body takes place in the following process steps: Introduction of a dike crown or embankment in the depth of the dyke body extending trench with extension in the longitudinal direction of the dike, • expire the trench with a protective wall of a building material of mineral aggregates and an organic adhesive, compaction of the building material and curing of the building material.
- the gravel is applied in layers up to a height of 300 mm and then bonded with an organic adhesive.
- FIG. 2 shows a schematic cross section of a dyke with a protective wall extending into the dyke body
- FIG. 3 shows a schematic cross section of a dyke with a protective wall placed on the slope
- FIG. 4 a cross section of a dike with a patch on a pedestal
- Fig. 1 shows the typical trapezoidal cross section of a dike.
- the dike body 1 builds above the ground 2.
- the so-called dyke storage the dyke body 1 runs on the water side and on the land side in tongue-shaped berms 3.
- dike crown 4 of the dike body 1 closes upwards from. It is usually inclined or dished for drainage towards the water. It is, if not passable, protected with turf against erosion (erosion).
- Land-based berms 3 increase the stability and usually carry the dyke defense route, which is used for dike maintenance and disaster floods of dike defense.
- the dyke defense paths must therefore permit speedy, safe traffic in terms of routing, dimensions and attachment in the event of a disaster, and be able to absorb the burden of heavy vehicles and equipment.
- FIG. 2 a first embodiment of the invention is shown in FIG. 2, in which the trapezoidal dike body 1 has a vertical protective wall 5 for its sealing against erosion.
- the substantially flat, plate-shaped protective wall 5 extends in the longitudinal direction of the dike and in its height from the ground 2 to the dike crown 4. About one fifth of the height of the protective wall 5 extends into the ground 2. With its crown-side end closes the protective wall 5 flush with the dike crown 4 and could serve as part of a dike not shown.
- the protective wall 5 also extends beyond the dike crown 4.
- the protective wall 5 is composed of a plurality of adjacent wall elements. Obviously, the wall thickness dw of the protective wall 5 is significantly smaller than the extent in height hw and length
- the building material of the protective wall 5 is a combination of sand and an organic adhesive. Mineral aggregates such as sand.
- the grain size is between 0.1 to 0.3 mm, so the protective wall is practically waterproof, thus preventing a wetting or flushing of the dam body.
- FIG. 4 A second embodiment of a dyke can be seen in FIG.
- the protective wall 5 is inclined at an inclination angle ⁇ to the ground 2 level and applied to the water-side slope 6.
- the inclination angle ⁇ is equal to the slope angle ß.
- the height hw of the protective wall 5 barely exceeds the rated flood level.
- the protective wall extends to below the low water level in order to avoid erosion even at low water levels and to enable secure anchoring.
- An embodiment with respect to the second embodiment of improved stability of the böschungs paragraphen protective wall 5 is shown with the third embodiment in Fig. 4.
- Fig. 4 is an anchored in the water-side slope 6 base 7 for fixing the protective wall 5 against drifting or sagging at Unter Hughes.
