It was loaded on a truck bed of about 10 tons, loaded with a predetermined amount of soil, and then transported to a disposal site for disposal.

[0003]

In the above-mentioned conventional processing method, there is a problem that the truck becomes in a waiting time while loading the soil on the bed of the truck, and the operating efficiency of the truck is lowered. In addition, if it is not possible to secure a place to store the excavated soil, the excavation work cannot be performed until the truck arrives.On the other hand, the truck must move after loading the excavated soil. However, because the progress of excavation work affects the time, it was not possible to select a time zone with good road conditions for transportation. Furthermore, in this type of civil engineering work, excavation may be carried out deep into the ground, and since trucks cannot directly enter such deep-drilling sites, the excavated earth excavated deep into the ground Have to be loaded onto a truck bed using a heavy equipment such as a crane, or transferred to a truck bed using a separate lift device, etc. was there. Further, in the conventional truck transportation, there is a possibility that the soil discharged on the bed becomes dust during transportation and pollutes the road or the houses near the road. And the biggest problem is that when using a conventional truck with a loading capacity of 7 tons or 10 tons, there is a limit to the actual loading capacity, and the transportation cost is relatively large in the soil disposal process. As a result, it has been an obstacle to cost reduction in soil disposal.
