Abstract

PURPOSE: To raise the passing rote of the secondary sereening, reduce the loss due to the drop from a material conveyor and thus improve the yield rote by applying a soil-quality improving agnet dividedly to stages after the 1st screening and after 2nd screening, in the praoving method for the quality of the edcavated earth having viscosity.
CONSTITUTION: To the excavated earth(a) whose quality is to be improved left after coarse alien substances being removed through the primary screening 1 is supplied addingly a fixed quantity of improving agent (b) by the primary supplying device 15 for a fixed quantity of earth-quality improving agent. After that, the primary crushing and mixing by a crusher 5 are performed and the excavated earth is turned to be the excavated earth (a1) whose viscosity is turned lower than the excavated earth (a) to which the primary treatment is applied. Next, the excavated earth (a1) being conveyed to the secondary screening 9 by a conveyor 7, excavated (a1) having earth passed through the secondary screening q is made to have a fixed thickness on a belffeeder 11 by an exessive earth removing machine 12. To the excavated earth (a1 thus made to have the fixed thickness is added a fixed quantity of improving agent (b2) by the secondary supplying devcice 16 for a fixed quantity of the earthquality improving agent, and, the secondary crushing and mixing being performed by another crusher 19, thus the excavated earth is turned to be the improved earth (c).
