Abstract:
A breach filling apparatus for plugging a hole in a structure, said breach filling apparatus comprising:an air supply assembly for supplying pressurized air; a converting assembly for converting air pressure to lineal movement, the converting assembly being connected to the air supply assembly; a component storage assembly for storing fluid components of a foaming material therein and expelling the components upon lineal movement by the converting assembly, the component storage assembly having an outlet for outputting the components stored in the component storage assembly; an outlet conduit in fluid communication with the outlet of the component storage assembly for receiving the components outputted from the component storage assembly; a plugging assembly for plugging a hole through a wall structure, the plugging assembly comprising: an inflatable flexible bladder having an interior space for receiving the fluid components and expanding in size from a collapsed condition to an expanded condition, the flexible bladder having an outer wall defining the interior space; and a mixing tube in fluid communication with the outlet conduit and extending into the interior space of the flexible bladder for expelling the components into the interior space of the flexible bladder, the mixing tube having a plurality of apertures therein for dispensing the components from the mixing tube into the interior space of the flexible bladder; wherein the flexible bladder has a first portion, a second portion and a linking portion extending between and linking the first and second portions, the first and second portions generally having a disc shape with substantially planar inner and outer faces when the flexible bladder is in the expanded condition, the linking portion extending between the inner faces of the first and second portions.
