[Function] A large amount of construction surplus soil carried in is dispersed into a large number of primary sorters 3 and is put into the hopper. Large lumps are sorted out and removed by a vibrating screen installed thereunder. After being separated into fine particles and passed through a crusher installed below the crusher to be crushed into fine particles, the solidified material adding device 8 is loaded into the container 6 and transferred along the transfer line 7. As a result, an amount of solidified material corresponding to the amount of loaded earth and sand is automatically added.

[0007] The added solidified material is automatically stirred and mixed into the earth and sand by the twin-screw paddle mounted on the container 6 while the container 6 is being transported. By reversing, it is discharged and transferred to the carry-out devices 10 and 11 and carried out.

Accordingly, a series of operations from the loading of the residual soil to the improvement treatment and the removal of the residual soil are automated, and a large amount of the residual soil can be efficiently processed at a low cost for various purposes (backfilling, subgrade, backfill, backfilling, etc.). Road, river embankment, residential land development, landfill, etc.)
Can be used effectively.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A number of primary sorters 3 for dispersing and feeding a large amount of construction waste brought in from a carry-in entrance 2 are provided in a covered soil disposal center 1, and each primary sorter 3 is put in. The remaining soil is received by a hopper, and large lumps such as concrete shells and wood chips are sorted out and removed by a vibrating screen installed underneath, and the earth and sand that has passed through the screen is subjected to a magnetic separator to remove iron debris, and further below. Through a crusher installed in a crusher to break it into fine particles of 1 cm or less.

The large lumps and iron scraps sorted by the primary sorting device 3 are discharged to the large lumps storage 5 by the belt conveyor 4, and the fine and crushed earth and sand is placed on the lower side such as a minecart. The paper is discharged and loaded in the transfer container 6.

The container 6 is a stirrer for stirring the earth and sand loaded thereon, for example, a biaxial paddle (two stirring shafts with stirring blades rotating in opposite directions) and the weight of the earth and sand, and a signal of the measured value is sent. A transmitting weighing device is provided at the bottom, and is automatically moved by a traction device such as a circulating drive wire installed along the transfer line 7 (the weighing device is installed on the transfer line 7 and is placed on the transfer line 7). The amount of loaded earth and sand may be calculated by measuring the passing container 6).

In the middle of the container transfer line 7, upon receiving a signal indicating the weight of the earth and sand loaded on the container 6, a solidifying material such as ordinary Portland cement in an amount commensurate with the quality (water content, etc.) of the earth and sand and the weight of the earth and sand is loaded. A solidifying material adding device 8 for discharging into the inside is installed, and the solidifying material automatically added in a predetermined amount is automatically stirred into the earth and sand by the twin-screw paddle mounted on the container 6 while the container 6 is being transferred. Mixed.

At the end of the container transfer line 7, there is provided a reversing machine 9 for automatically lifting the container 6 having moved to this position with a rotating arm or the like and reversing the container 6 by about 180 ° so that the opening is downward, Below the reversing part, there is provided an unloading device for the treated soil which has been improved with a solidifying material so as to cross the reversing portion, for example, a unloading capsule 11 which can be freely moved by a linear motor, air pressure, or the like in a tubular running path 10. A loaded device or the like is installed, and the treated soil discharged by inverting the container 5 is automatically stopped at this position and put into the standby carrying-out capsule 11 to an appropriate place outside the residual soil processing center 1. It is designed to be transported.

It is to be noted that a transporting vehicle such as various conveyors and dump trucks can be employed as an apparatus for unloading the treated soil.
