Protective wall, dyke and method of producing a dyke

Abstract

The protective wall ( 5 ) has a flat, tabular or cubic configuration which has a section of a water-impermeable building material. The building material of the protective wall is a compound of compacted, mineral aggregates and an organic adhesive. Mineral aggregates such as sand or gravel are building materials which occur in plentiful amounts in nature and can be acquired simply and inexpensively in large quantities on-site. Mixed with an organic adhesive, the building material has a viscous consistency and can be produced and processed easily. By means of appropriate shaping, the protective wall can be configured in a variety of dimensions, frequently curved. The protective wall is suitable for sealing dykes to protect them against erosion in coastal or liquid-side high-water protection.

       6 . The protective wall as claimed in  claim 1  wherein the adhesive is an adhesive that can be cured under the effect of water. 
   
   
       7 . The protective wall as claimed in  claim 1  wherein the adhesive is one of a two-component epoxy resin adhesive, a single-component polyurethane adhesive, and a two-component polyurethane adhesive. 
   
   
       8 . The protective wall as claimed in  claim 1  wherein the permeability coefficient k f  of the construction material is at most 5×10 −10  m/s. 
   
   
       9 . The protective wall as claimed in  claim 1  wherein the density of the protective wall is greater than that of water. 
   
   
       10 . The protective wall as claimed in  claim 1  wherein the protective wall has an addition of steel. 
   
   
       11 . The protective wall as claimed in  claim 1  wherein the wall thickness d w  of the protective wall is smaller than the wall's extent in height h w  and length l w . 
   
   
       12 . A dyke, in particular for river and sea dykes, comprising a dyke body which essentially has a trapezoidal cross section, the dyke having a dimensionally stable protective wall formed between an inner slope and an outer slope and extending in the dyke longitudinal and vertical directions; wherein the dyke has a protective wall designed according to  claim 1 . 
   
   
       13 . The dyke as claimed in  claim 12 , wherein the protective wall extends right under the dyke body into a foundation. 
   
   
       14 . The dyke as claimed in  claim 12  wherein the protective wall extends right into one of a dyke crown and ends at one of the inner slope and the outer slope. 
   
   
       15 . A dyke, in particular for river and sea dykes, comprising a made-up dyke body and a slope on the water side and land side; and a dimensionally stable protective wall being situated in front of the water-side slope; wherein the dyke has a protective wall designed according to  claim 1 . 
   
   
       16 . The dyke as claimed in  claim 15 , wherein the protective wall rests on the slope. 
   
   
       17 . The dyke as claimed in  claim 15  wherein the protective wall has an angle of inclination α of 15 to 90 degrees relative to the water surface. 
   
   
       18 . The dyke as claimed in  claim 17 , wherein the angle of inclination α is equal to a slope angle β. 
   
   
       19 . The dyke as claimed in  claim 12  wherein the dyke has a base which is anchored in at least one of the slope a foundation and carries the protective wall. 
   
   
       20 . The dyke as claimed in  claim 12  wherein the protective wall extends from the dyke body into a foundation. 
   
   
       21 . The dyke as claimed in  claim 12  wherein the dyke has a plurality of wall elements which adjoin one another in the dyke longitudinal direction. 
   
   
       22 . The dyke as claimed in  claim 12  wherein the dyke has a plurality of wall elements staggered in a depth direction of the dyke. 
   
   
       23 . The dyke as claimed in  claim 22 , wherein the wall elements staggered in the depth direction have wall heights differing from one another. 
   
   
       24 . A method of producing a dyke as claimed in  claim 12  comprising:
 incorporating a trench which extends from one of a dyke crown and the slope into a depth of the dyke body and in a longitudinal direction of the dyke;   filling the trench with a protective wall made of a construction material consisting of mineral aggregates and an organic adhesive;   compacting the construction material; and   curing the construction material.   
   
   
       25 . The dyke as claimed in  claim 15 , wherein the protective wall projects at least partly into the slope.
