Abstract
Abstract According to this invention, when the area to be treated is accessible, the procedure involves breaking up the soil to be treated by a continuous, forward-moving mixing process down to a chosen depth. A first vertical section of a determined width is followed, with simultaneous forward injection of the reagent. This is continued until the first section has been completed, at which time a second lateral section is begun in the same way. This second section will be exactly adjacent to the first one, which will be in the process of hardening, and the following sections will be completed in the same way until the entire area to be treated has been mixed to the desired depth.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
117 words
A method for on-site treatment of mud and silt by a mixing process with simultaneous injection of a reagent for the purposes of stabilization and solidification, the method comprising breaking up of a first vertical section of a given width of the soil by a continuous forward-moving mixing process down to a given depth while simultaneously injecting said reagent forwardly into said soil until said first section is completed, initiating treatment of a second adjacent section in the same manner and disposed adjacent said first section while said first section is in the process of hardening, and completing subsequent sections in the same manner until the entire area to be treated is mixed to the desired depth.
Claim 2
Independent Claim
117 words
A method for on-site treatment of mud and silt by a mixing process with simultaneous injection of a reagent for the purposes of stabilization and solidification, the method comprising breaking up of a first vertical section of a given width of the soil by a continuous forward-moving mixing process down to a given depth while simultaneously injecting said reagent forwardly into said soil until said first section is completed, initiating treatment of a second adjacent section in the same manner and disposed adjacent said first section while said first section is in the process of hardening, and completing subsequent sections in the same manner until the entire area to be treated is mixed to the desired depth.
Claim 3
Independent Claim
194 words
A method for on-site treatment of mud and silt wherein the work site is relatively inaccessible by a mixing process with simultaneous injection of a reagent for the purposes of stabilization and solidification, the method comprising breaking up of a first vertical section of a given width of the soil by a continuous forward-moving mixing process down to a given depth from the banks of solid ground around said soil, beginning said first section on a plane which is inclined in the direction of the forward progress of the mixing, forcing the layers of mixed soil upward in said inclined plane, mixing the lower rear layers at the same time as the upper front layers, continuing the forward progress of the mixing action combined with injection of reagent until said first section extends around the outer edge of the area to be solidified in a complete circle, beginning a second section adjacent to the inner side of said first section and continuing until said second section is enclosed by said first section, and completing the following sections in a similar manner until the entire area has been treated, the central section being completed last.
Claim 4
Independent Claim
194 words
A method for on-site treatment of mud and silt wherein the work site is relatively inaccessible by a mixing process with simultaneous injection of a reagent for the purposes of stabilization and solidification, the method comprising breaking up of a first vertical section of a given width of the soil by a continuous forward-moving mixing process down to a given depth from the banks of solid ground around said soil, beginning said first section on a plane which is inclined in the direction of the forward progress of the mixing, forcing the layers of mixed soil upward in said inclined plane, mixing the lower rear layers at the same time as the upper front layers, continuing the forward progress of the mixing action combined with injection of reagent until said first section extends around the outer edge of the area to be solidified in a complete circle, beginning a second section adjacent to the inner side of said first section and continuing until said second section is enclosed by said first section, and completing the following sections in a similar manner until the entire area has been treated, the central section being completed last.
Claim 5
Dependent Claim
135 words
