Abstract

A vertical manhole apparatus for use in a waste facility to provide access to one or more leachate collection pipe access points. The vertical manhole is stabilized using stabilizing features extending out from a vertical pipe of the vertical manhole apparatus.

First claim

What is claimed is:

1 . A vertical manhole apparatus for providing access to one or more leachate collection pipe access points, the apparatus comprising:
a plurality of pipe segments joined together vertically above a foundation in a landfill wherein the plurality of pipe segments form a vertical pipe and wherein a first pipe segment includes a first aperture of the first pipe segment extending through a wall of the first pipe segment; a first cable extending through the first aperture of the first pipe segment; a first deadman anchor connected to a first end of the first cable and located in a first mass of waste in the landfill; and a tension control system wherein a second end of the first cable is connected to the tension control system and wherein the tension control system controls the tension of the first cable by increasing or decreasing the tension of the first cable between the tension control system and the first deadman anchor.

2 . The vertical manhole apparatus of claim 1 further comprising:
at least three apertures extending through the wall of the first pipe segment, the at least three apertures comprising the first aperture of the first pipe segment, a second aperture of the first pipe segment, and a third aperture of the first pipe segment;
a second deadman anchor;
a second cable extending through the second aperture of the first pipe segment wherein a first end of the second cable is connected to the second deadman anchor which is located in a second mass of waste in the landfill and wherein a second end of the second cable is connected to the tension control system;
a third deadman anchor;
a third cable extending through the third aperture of the first pipe segment wherein a first end of the third cable is connected to the third deadman anchor which is located in a third mass of waste in the landfill and wherein a second end of the third cable is connected to the tension control system; and
the tension control system for controlling the tension of the second cable by increasing or decreasing the tension between the second deadman anchor and the tension control system and for controlling the tension of the third cable by increasing or decreasing the tension between the third deadman anchor and the tension control system.

3 . The vertical manhole apparatus of claim 1 further comprising a protective sleeve surrounding at least a portion of the first cable.

4 . The vertical manhole of claim 3 wherein the protective sleeve further comprises a first protective sleeve member and a second protective sleeve member wherein the first protective sleeve member is narrower that the second protective sleeve member such that the first protective sleeve member is configured to slide at least partially inside of the second protective sleeve member.

5 . The vertical manhole apparatus of claim 2 wherein the first aperture of the first pipe segment, the second aperture of the first pipe segment, and the third aperture of the first pipe segment are separated from one another along the wall of the first pipe segment by approximately 120 degrees.

6 . The vertical manhole apparatus of claim 2 further comprising a cleanout riser pipe extending adjacent to the vertical pipe from a cleanout riser pipe access point to a collection pipe access point proximate a leachate collection pipe.

7 . The vertical manhole apparatus of claim 2 further comprising:
a first cable roller attached adjacent to the first aperture of the first pipe segment wherein the first cable roller is provided to allow the first cable to roll or slide easily along the first cable roller as the tension of the first cable is controlled by the tension control system;
a second cable roller attached adjacent to the second aperture of the first pipe segment wherein the second cable roller is provided to allow the second cable to roll or slide easily along the second cable roller as the tension of the second cable is controlled by the tension control system; and
a third cable roller attached adjacent to the third aperture of the first pipe segment wherein the third cable roller is provided to allow the third cable to roll or slide easily along the third cable roller as the tension of the third cable is controlled by the tension control system.

8 . The vertical manhole apparatus of claim 2 wherein the tension control system comprises a cable winch.

9 . The vertical manhole apparatus of claim 2 wherein the tension control system comprises a first cable winch connected to the first cable, a second cable winch connected to the second cable, and a third cable winch connected to the third cable.

10 . The vertical manhole apparatus of claim 2 further comprising:
the plurality of pipe segments further comprising a second pipe segment which includes at least one aperture extending through the wall of the second pipe segment, the at least one aperture including a first aperture of the second pipe segment;
a fourth deadman anchor;
a fourth cable extending through the first aperture of the second pipe segment wherein a first end of the fourth cable is connected to the fourth deadman anchor which is located in a fourth mass of waste in the landfill and wherein a second end of the fourth cable is connected to the tension control system; and
the tension control system for controlling the tension of the fourth cable by increasing or decreasing the tension between the fourth deadman anchor and the tension control system.

11 . The vertical manhole apparatus of claim 8 further comprising:
the second pipe segment further comprising at least three apertures extending through the wall of the second pipe segment, the at least three apertures including the first aperture of the second pipe segment, a second aperture of the second pipe segment, and a third aperture of the second pipe segment;
a fifth deadman anchor;
a fifth cable extending through the second aperture of the second pipe segment wherein a first end of the fifth cable is connected to the fifth deadman anchor which is located in a fifth mass of waste in the landfill and wherein a second end of the fifth cable is connected to the tension control system;
a sixth deadman anchor;
a sixth cable extending through the third aperture of the second pipe segment wherein a first end of the sixth cable is connected to the sixth deadman anchor which is located in a sixth mass of waste in the landfill and wherein a second end of the sixth cable is connected to the tension control system;
the tension control system for controlling the tension of the fifth cable by increasing or decreasing the tension between the fifth deadman anchor and the tension control system and for controlling the tension of the sixth cable by increasing or decreasing the tension between the sixth deadman anchor and the tension control system.

12 . The vertical manhole apparatus of claim 10 wherein the first aperture of the first pipe segment is offset from the first aperture of the second pipe segment by approximately 60 degrees.

13 . A vertical manhole apparatus for providing access to one or more leachate collection pipe access points, the apparatus comprising:
a plurality of first pipe segments joined together vertically above a foundation in a landfill including a first pipe first segment wherein the plurality of first pipe segments form a first vertical pipe; a cleanout riser pipe extending inside the first vertical pipe from a cleanout riser pipe access point to a collection pipe access point proximate a leachate collection pipe; and a first stabilizer engaged with the first pipe first segment and extending from the first pipe first segment o
