Abstract
Abstract An object of the invention is rapid fabrication of sealed tracks for trash-dump construction to assure reliable protection even on slopes. The invention proposes a protective element 1,15,21,33 in the shape of a shallow container with essentially constant height that receives a filling of sand 10,36 or a sand-like bulk material and which spans its space in such a way that a plurality of such can be laid as a gapless compound into a protective layer.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
79 words
A method of sealing trash-dump bottoms, comprising the steps of: a) depositing a sealed protective layer over the surface of the bottom of a trash-dump; b) providing a plurality of protective elements, each element constructed as a flat container of substantially constant height and each container filled with granular bulk material; and c) laying the elements in gapless arrangement by overlapping a portion of each element with an adjacent element over the sealed layer for protecting the sealed layer.
Claim 2
Independent Claim
79 words
A method of sealing trash-dump bottoms, comprising the steps of: a) depositing a sealed protective layer over the surface of the bottom of a trash-dump; b) providing a plurality of protective elements, each element constructed as a flat container of substantially constant height and each container filled with granular bulk material; and c) laying the elements in gapless arrangement by overlapping a portion of each element with an adjacent element over the sealed layer for protecting the sealed layer.
Claim 3
Dependent Claim
23 words
The method of claim 1, including the step of: a) filling each container with sand or a sand-like material as the bulk material.
Claim 4
Dependent Claim
25 words
The method of claim 2, including the step of: a) forming each container as a closed sack having peripheral walls formed from a textile material.
Claim 5
Dependent Claim
32 words
The method of claim 3, including the step of: a) providing each sack with a plurality of spacers therein so that opposite surfaces thereof are no more than a selected distance apart.
Claim 6
Dependent Claim
28 words
The method of claim 3, including the step of: a) selecting the textile material forming the peripheral walls from materials impermeable to the bulk material filling each sack.
Claim 7
Dependent Claim
21 words
The method of claim 5, including the step of: a) providing textile for the walls having a stabilizing coating applied thereto.
Claim 8
Dependent Claim
22 words
The method of claim 1, including the stem of: a) providing each flat container as a trough having upwardly projecting side rims.
Claim 9
Dependent Claim
17 words
The method of claim 7, including the step of: a) closing each trough along the top thereof.
Claim 10
Dependent Claim
21 words
The method of claim 7, including the step of: a) providing each trough with dividing walls extending along the interior thereof.
Claim 11
Dependent Claim
27 words
The method of claim 1, including the step of: a) applying a geotextile layer onto the protective elements after they have been laid along the sealed layer.
Claim 12
Dependent Claim
38 words
The method of claim 1, including the step of: a) causing a portion of each protective element to be overlaid upon a portion of the immediately adjacent protective element for therewith providing a gapless connection between the elements.
Claim 13
Dependent Claim
25 words
The method of claim 2, including the step of: a) filling each container with sand having a grain size of no more than 3 millimeters.
Claim 14
Independent Claim
96 words
A method of sealing trash-dump bottoms, comprising the steps of: a) depositing a sealed protective layer over the entire surface of the bottom of a trash-dump; b) providing a plurality of protective elements, each element formed from fabric and constructed as a flat container of substantially constant height and each container filled with a granular bulk material; and c) laying the protective elements in gapless arrangement by overlapping adjacent portions of the protective elements so that the protective elements are in juxtaposition to and over the entirety of the sealed layer for protecting the sealed layer.
Claim 15
Independent Claim
96 words
A method of sealing trash-dump bottoms, comprising the steps of: a) depositing a sealed protective layer over the entire surface of the bottom of a trash-dump; b) providing a plurality of protective elements, each element formed from fabric and constructed as a flat container of substantially constant height and each container filled with a granular bulk material; and c) laying the protective elements in gapless arrangement by overlapping adjacent portions of the protective elements so that the protective elements are in juxtaposition to and over the entirety of the sealed layer for protecting the sealed layer.
Claim 16
Dependent Claim
23 words
The method of claim 13, including the step of: a) filling each container with sand or a sand-like material as the bulk material.
Claim 17
Dependent Claim
25 words
The method of claim 14, including the step of: a) filling each container with sand having a grain size of no more than three millimeters.
Claim 18
Dependent Claim
29 words
The method of claim 13, including the step of: a) applying a geotextile layer onto the protective elements after the protective elements have been laid over the sealed layer.
Claim 19
Dependent Claim
29 words
The method of claim 13, including the step of: a) selecting the fabric from which the protective elements are formed from those fabrics having a stabilizing coating applied thereto.
Claim 20
Dependent Claim
27 words
The method of claim 1, including the step of: a) forming each element with strips projecting laterally therefrom for providing the overlap portion for the adjacent element.
Claim 21
Dependent Claim
27 words
The method of claim 13, including the step of: a) forming each element with strips projecting laterally therefrom for providing the overlap portion for the adjacent element.
