METHODS FOR IN-PLACE TREATMENT, SLUDGE AND SLUDGE, FOR STABILIZATION AND SOLIDIFICATION, AND DEVICES FOR THEIR IMPLEMENTATION

摘要

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.
