Delivery methods and processes for encapsulating waste in situ

Abstract

A system for depositing material includes: an elongate rotatable casing for placement into a substrate material; a non-rotatable conveyance pipe having a segment within the casing; a rotary union in the casing coupled to the segment; a rotatable conveyance pipe in the casing below the rotary union and coupled to the segment via the rotary union; an outlet pipe having a first end flexibly coupled to the rotatable conveyance pipe; a chute hingedly connected to and rotatable with the casing and configured to open and close. The casing is rotated as material is pumped into the conveyance pipe or a section of rotatable conveyance pipe attached to the segment by a pipe swivel joint. The material flows from the conveyance pipe and into the rotatable conveyance pipe through the rotary union, from the conveyance pipe into the outlet pipe, and from the outlet pipe onto or into the substrate material.
