EFFECTS OF THE INVENTION Since the method and the device of the present invention are configured as described above, as described in the section of the action, the excavated residual soil generated in the burial work such as water supply and sewerage on the road etc. is sequentially processed in steps Then, it selects coarse aggregate, fine aggregate, sand content, and mud from the discharged soil, and the coarse and fine aggregate is used as aggregate for concrete, and the sand content is buried pipe. If you use it as a sand cushion or barrier layer material, etc., and prepare the reclaimed soil by adding only the remaining mud to the stabilization treatment material such as quick lime and crushed concrete, if the mud amount is 40%,
By adding 20% and a few% of quick lime, 60% or more of the reclaimed soil can be obtained, and this reclaimed soil alone can be used to backfill the site.
In normal buried pipe work, there is a unique effect that the work can be completed without carrying out excavated soil and carrying in the buried soil.
