APPLICATIONS IN HORIZONTAL HOLES / PIPES

The FLUTe liner mechanism described in Basic Eversion Process is especially well suited to installations that are long and tortuous and in any direction. The mechanism is used for carrying things into horizontal holes built beneath landfills.

Devices that can be carried beneath landfills include:

• moisture sensing logging tools,
• absorbers for collecting liquids,
• gas sampling tubing,
• radiation detectors, etc…

Other applications in angled holes are:

• mapping of vadose zone fractures with color reactive covers,
• Multi Level Sampling,
• pore gas sampling,
• sealing and supporting the borehole

An especially attractive method is the towing of sensors into remote passages where the hazard to human entry is large or otherwise prohibited. Robotic functions of several kinds have been effected including the towing and emplacement of heavy objects on the ground surface where the terrain might limit the use of vehicles.

Leak checking uses are especially attractive since a pair of liners can seal a pipe while an interval between them can be sampled or injected. This concept is patented and called a Progressive Packer.

Liners have even been used to emplace cure-in-place permanent liners in the cast iron pipes in the walls of the Smithsonian Museum of Natl. History in Washington DC. These were installed from the basement to nearly 100 ft. to the roof.

Because the liner installations do not require the aid of gravity, and the liners can be everted around corners, the uses are only limited by the imagination.

A relatively new application developed by FLUTe uses the everting liner to augment the drilling of horizontal holes for a variety of conditions and applications (LAHD system).
