Abstract
Abstract Dry lawn construction wherein the internal space formed by the lateral vegetation mats (28, 30) is self-ballasted with a self-supporting substrate (12) which is rendered stable by checking or compaction and used as a nutrient medium for growing plants from the vegetation mats. The supports and auxiliary technical constructions are thus simplified. Furthermore, it is possible to set the plant bearing wall even in locations which are extremely arid since the substrate and the vegetal growth form a self-maintaining system.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
132 words
A static, vertically extending plant growth and noise abatement structure which is taller than it is wide, the structure including: at least two spaced-apart, static, generally A-shaped support means; anchor means for said static support means; a plurality of flexible support means interconnecting parallel legs of said static support means; flexible vegetative mat means adpressed against the inside surfaces of said flexible support means to define two generally upwardly extending sides; and a structurally stable, self-supporting non-phytotoxic substrate mixture contained between said sides, said mixture including at least one porous aggregate material, at least one filler material, at least one hygroscopic material, and at least one binding material, whereby the structure may be installed by compacting the substrate mixture between said sides to serve as a medium for plants to be grown.
Claim 2
Dependent Claim
132 words
A static, vertically extending plant growth and noise abatement structure which is taller than it is wide, the structure including: at least two spaced-apart, static, generally A-shaped support means; anchor means for said static support means; a plurality of flexible support means interconnecting parallel legs of said static support means; flexible vegetative mat means adpressed against the inside surfaces of said flexible support means to define two generally upwardly extending sides; and a structurally stable, self-supporting non-phytotoxic substrate mixture contained between said sides, said mixture including at least one porous aggregate material, at least one filler material, at least one hygroscopic material, and at least one binding material, whereby the structure may be installed by compacting the substrate mixture between said sides to serve as a medium for plants to be grown.
Claim 3
Dependent Claim
19 words
The structure as defined in claim 1, wherein said substrate mixture includes a nutrient medium for said plant growth.
Claim 4
Dependent Claim
21 words
The structure as defined in claim 1, wherein the sides of said structure taper upwardly and inwardly toward the center thereof.
Claim 5
Dependent Claim
53 words
The structure as defined in claim 1, wherein said substrate mixture includes 30% by volume 0-45 mm oolite and dolomite gravel, 20% by volume 0-65 mm. lava or slag, 5% by volume clay, 20% by volume soluble loam B- or C-stratum, 15% by volume bark humus, and 10% by volume modified trass-lime mortar.
Claim 6
Dependent Claim
20 words
The structure as defined in claim 1, wherein said static, generally A-shaped support means are formed of synthetic resin concrete.
Claim 7
Dependent Claim
21 words
The structure as defined in claim 1, wherein said substrate mixture includes lava, sand, a swelling clay, lime gravel and basalt.
Claim 8
Dependent Claim
23 words
The structure as defined in claim 6, wherein the lava and lime gravel components of said substrate mixture are coated with bark humus.
Claim 9
Dependent Claim
24 words
The structure as defined in claim 1, wherein said flexible support means comprises a plurality of parallel ropes stretched between said static support means.
Claim 10
Dependent Claim
26 words
The structure as defined in claim 8, wherein said flexible vegetative mat means have outwardly directed buckling between adjacent ropes thereby enlarging the surface of structure.
Claim 11
Dependent Claim
17 words
The structure as defined in claim 1, wherein said at least one hygroscopic material includes modified mortar.
Claim 12
Dependent Claim
21 words
The structure as defined in claim 10, wherein said modified mortar is a modified trass-lime mortar with bentonite as an aggregate.
Claim 13
Dependent Claim
24 words
The structure as defined in claim 11, wherein the amount of modified trass-lime mortar in said substrate is from 8 to 10% by volume.
Claim 14
Dependent Claim
32 words
The structure as defined in claim 12, wherein said modified trass-lime mortar is blended in the dry state with about 10% by volume betonite meal and about 5% by volume Portland cement.
Claim 15
Dependent Claim
17 words
The structure as defined in claim 12, wherein said substrate includes about 15% by volume bark humus.
