## Abstract

Auger cleaned inaccessible floor systems to maximize operational capacity of inaccessible floors. The auger cleaned inaccessible floor system includes a floor having at least one channel beneath the lowest point of the floor extending horizontally at least half the length of the longest dimension of the floor and adapted for receiving an auger cleaner, at least one gate complex that provides fluid communication between the channel and at least one box and further provides access to the floor for the auger cleaner, and at least one box to deliver the auger cleaner to the channel and adapted for equalizing pressure when the inaccessible floor is under water to deliver an auger cleaner for cleaning. Thus, the auger cleaned inaccessible floor system allows cleaning of the inaccessible floor while the inaccessible floor system is in operation increasing the yield from the inaccessible floor system.

## Claims

### Claim 1

An auger cleaned inaccessible floor system for cleaning waste from the inaccessible floor, comprising:
a floor, the floor including
at least one longitudinal channel beneath the lowest point of the floor and extending at least half a longest dimension of the floor, the channel in fluid communication with the floor and configured to receive an auger cleaner;
at least one box in fluid communication with the channel having a box interior volume,
the at least one box including
a lid, where the lid is removably attached to the box;
a rail attached in the box interior volume for fixing a boom, the boom attaching and directing movement of the auger cleaner;
a waste discharge pipe in fluid communication with the boom for disposal of waste;
at least one gate complex separating the box from the channel, the gate complex including
a gate; and
a gate controller to move the gate complex to an open position and a closed position, wherein
in the open position the gate complex provides
fluid communication between the channel and the box and
the auger cleaner with access to the channel of the floor from the box, and
in the closed position the gate complex hinders fluid communication between the channel and the box.

### Claim 2 (depends on 1)

The system of claim 1, further comprising
the auger cleaner adapted for longitudinal movement in the channel to remove waste from the channel, the auger cleaner including
an auger that spins perpendicular to the channel transporting waste toward an eddy sludge pump of the auger cleaner;
the eddy sludge pump in fluid communication with the auger and configured to pump the waste to a waste transfer component of the boom; wherein
the auger cleaner is removably attached to the boom, and
the auger cleaner is in fluid communication with a waste transfer component of the boom;
the boom being multi-segmented and configured to extend and retract horizontally to move the auger cleaner longitudinally in the channel, the boom including
the waste transfer component that transfers waste from the auger cleaner to the waste disposal pipe, wherein
the boom is removably attached to the rail of the box, and
the waste transfer component and the waste disposal pipe are in fluid communication; and
a hydraulic circuit to power the auger cleaner and the boom, wherein
the auger cleaner is in fluid communication with the hydraulic circuit, and
the boom is in fluid communication with the hydraulic circuit.

### Claim 3 (depends on 1)

The system of claim 1, wherein
the at least one channel is half the length of the longest dimension of the floor; and
the floor is circular in shape, the floor further including
a sloped segment sloped in a conical manner toward the at least one channel;
a first sloped quadrant sloped toward the at least one channel and the at least one gate complex;
a second sloped quadrant sloped toward the at least one channel and the at least one gate complex, wherein
the sloped segment, the first sloped quadrant, and the second sloped quadrant are formed as a single unit.

### Claim 4 (depends on 3)

The system of claim 3, wherein
the slope of the sloped segment, the first sloped quadrant, and the second sloped quadrant is from 8 to 12 percent (length to height).

### Claim 5 (depends on 1)

The system of claim 1, further comprising
one channel the length of the longest dimension of the floor;
the floor is rectangular in shape and sloped inward toward the channel;
two gate complexes; and
two boxes, wherein
the two gate complexes provide
fluid communication between each end of channel and the two boxes and
the auger cleaner with access to the channel of the floor from the two boxes.

### Claim 6 (depends on 1)

The system of claim 1, further comprising
one channel the length of the longest dimension of the floor;
the floor is rectangular in shape and sloped inward toward the one channel;
a false floor configured to allow waste to pass through to the floor; and
a plurality of slats, wherein
the slats extend upward from the floor to support the false floor;
two gate complexes; and
two boxes, wherein
the two gate complexes provide
fluid communication between each end of channel and the two boxes and
the auger cleaner with access to the channel of the floor from the two boxes.

### Claim 7 (depends on 1)

The system of claim 1, further comprising
two channels extending the length of the of the longest dimension of the floor, wherein
the two channels are on opposite sides of a shortest longest dimension of the floor;
the floor is rectangular in shape and sloped along substantially a center of the shortest dimension of the floor downward toward the two channels;
four gate complexes;
and four boxes, wherein
the four gate complexes provide
fluid communication between each end of the two channels corresponding to the four boxes, and
the auger cleaner with access to the two channels from the four boxes.

### Claim 8 (depends on 7)

The system of claim 7, wherein
the slope of the floor is from 2 to 4 percent (length to height).
