Abstract
Abstract A method for increasing the capacity of a garbage dump to allow additional garbage to be dumped therein, in which a depth packing device, such as a vibrator or ram, is lowered from the surface of the dump down to a predetermined depth to form a hole surrounded by compacted garbage; additional garbage is then placed in the hole and additionally compacted by the same depth packing device used to form the hole. If a vibrator is used, the additional garbage is dispensed from the vibrator tip as the vibrator is withdrawn from the hole so that a compacted column of garbage is formed. A ram device comprising a pipe having a removable closure at the lower end may also be used. As the pipe is withdrawn from the hole, additional garbage is placed through it and out through the lower closure; the additional garbage is compacted with a weight guided through the pipe.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
139 words
A method for gaining garbage dump space by means of sequentially compacting areas of a garbage-containing dump mass; said method comprising the following steps: a) forming a hole suitable for receiving additional garbage in the dump mass by introducing a depth packing device selected from the group consisting of a depth vibrator which imparts vibration energy, and a ram device which imparts impact energy, into the dump mass to a planned depth, starting from the dump surface, said depth packing device exerting said energy on the garbage of the dump mass to displace it and to precompact it surrounding the hole, b) placing additional garbage into the hole, and c) packing and compacting the additional garbage in the region of the hole by means of said energy exerted by the same depth packing device used for forming the hole.
Claim 2
Independent Claim
139 words
A method for gaining garbage dump space by means of sequentially compacting areas of a garbage-containing dump mass; said method comprising the following steps: a) forming a hole suitable for receiving additional garbage in the dump mass by introducing a depth packing device selected from the group consisting of a depth vibrator which imparts vibration energy, and a ram device which imparts impact energy, into the dump mass to a planned depth, starting from the dump surface, said depth packing device exerting said energy on the garbage of the dump mass to displace it and to precompact it surrounding the hole, b) placing additional garbage into the hole, and c) packing and compacting the additional garbage in the region of the hole by means of said energy exerted by the same depth packing device used for forming the hole.
Claim 3
Dependent Claim
15 words
The method according to claim 1, wherein said depth packing device is a depth vibrator.
Claim 4
Dependent Claim
84 words
The method according to claim 2, which comprises the following steps: a) introducing a depth vibrator, comprising at its lower end a vibrator tip, into the dump to the planned depth, starting from the dump surface, said depth vibrator displacing and precompacting the garbage it encounters, and b) withdrawing the vibrator and simultaneously packing garbage from bottom to top of said hole by introducing additional garbage substantially at the region of the vibrator tip so that a compacted column of packed garbage is formed.
Claim 5
Dependent Claim
14 words
The method according claim 1, wherein said depth packing device is a ram device.
Claim 6
Dependent Claim
110 words
The method according to claim 4, which comprises the following steps: a) introducing a ram device comprising a pipe having removable closure means at a lower end of said pipe into the dump to the planned depth, starting from the dump surface, said ram device displacing and precompacting the garbage that it encounters, b) introducing additional garbage substantially at the region of said lower end of the pipe, withdrawing the pipe in sections, with the lower end of the pipe being open, and c) compacting and packing the additional garbage by means of a drop weight guided in the pipe, so that a compacted column of packed garbage is formed.
Claim 7
Dependent Claim
21 words
The method according to claim 5, wherein instead of the drop weight, a static weight guided in the pipe is used.
Claim 8
Dependent Claim
23 words
The method according to claim 3 or 5, wherein garbage packing is carried out continuously while the depth packing device is being withdrawn.
Claim 9
Dependent Claim
24 words
The method according to claim 3 or 5, wherein garbage packing is carried out in stages, while the depth packing device is being withdrawn.
Claim 10
Dependent Claim
33 words
The method according to claim 1, wherein the steps of introducing the depth packing device and packing additional garbage are repeated at a horizontal distance from the holes packed with garbage previously formed.
Claim 11
Dependent Claim
18 words
The method according to claim 9, wherein the holes packed with garbage are formed offset to one another.
Claim 12
Dependent Claim
32 words
The method according to claim 1, wherein introduction of the depth packing device is accompanied by addition of a flushing medium selected from the group consisting of a gas and a liquid.
Claim 13
Dependent Claim
29 words
The method according to claim 11, wherein the addition of the flushing medium is reduced or terminated after the final depth of the depth packing device has been reached.
Claim 14
Dependent Claim
19 words
The method according to claim 1, wherein the steps (b) and (c) are carried out one after the other.
Claim 15
Dependent Claim
24 words
The method according claim 1, wherein the additional garbage is added via an annular space between the depth packing device and the hole wall.
Claim 16
Dependent Claim
27 words
The method according to claim 1, wherein the additional garbage is added via a material line guided at the outside or inside of the depth packing device.
Claim 17
Dependent Claim
29 words
The method according to claim 1, wherein the additional garbage is treated before being added by at least one of shredding to a desired size and compressing into pieces.
Claim 18
Dependent Claim
45 words
The method according to claim 1, wherein during garbage packing, the area is made inert by adding a flushing medium which provides an inert environment, with the flushing medium simultaneously acting as the transport medium for the ingoing flow of additional garbage to be packed.
Claim 19
Dependent Claim
37 words
The method according to claim 1, wherein the additional garbage to be added is treated by a treatment selected from biological and chemical treatments, to accelerate the biological decomposition of the pollutants contained in the dump mass.
