Abstract: A barrier panel system and a method of installing the barrier panel system is provided. The barrier panel system includes a barrier panel having a top and a bottom. The panel includes at least one channel extending from the top to the bottom of the barrier panel. A removable jet assembly unit can be connected to the panel within the channel. The removable jet assembly unit includes at least one cutter tool pipe which is connected to a jet head and at least one vacuum manifold. The jet head at the bottom of the cutter tool pipe delivers and directs the pressurized stream to transform the ground material into a form which is easily removable by a vacuum connected to the vacuum manifold. As the vacuum removes the ground matter, an opening is formed in the ground allowing the panel to sink. The barrier panel also includes interlocking features on the sides allowing them to be easily attached to one another horizontally to form an interconnected barrier wall system.
