it's really expensive, some "micro-surgery" might pay out, i.e. you
dig/drill a negligibly small hole down to the pipe, let nanobots
remove 18 inches of material below the pipe; then the pipe is lowered
by 18" and the void above it, which has a volume of 100" x 18" x 30',
is filled through the little hole with that expensive material. If the
hole is thin enough, filling it should be cheap.
